The application provides a pipeline cleaning system, as shown in fig. 1 and 2, fig. 1 is a schematic diagram of an internal structure of the pipeline cleaning system provided by the embodiment of the application, fig. 2 is a schematic diagram of an internal structure of a box 1 in fig. 1, and the pipeline cleaning system comprises a pipe cleaner 100, wherein the pipe cleaner 100 is used for cleaning impurities in a pipeline. The pipeline can be a crude oil pipeline, a natural gas pipeline and the like. The present application is illustratively described in terms of cleaning impurities in crude oil pipelines with a pig 100.
Specifically, the pig 100 is disposed in a pipeline (e.g., a crude oil pipeline), and the pig 100 is in sealing contact with an inner wall surface of the pipeline, so that as crude oil is continuously extracted, the crude oil is introduced into the pipeline after being processed (e.g., dehydrated, desalted, etc.) and transported through the pipeline, and as the processed crude oil continuously enters the pipeline, the pressure of a medium on one side of the pig 100 (i.e., a rear side of the pig 100 when moving) is gradually increased, and when a pressure difference across the pig 100 is sufficient to drive the pig 100 to move, the pig 100 is moved under the pushing of the medium.
The pig 100 has opposite first and second ends, the first end being forward of the second end during movement of the pig 100 within the tube.
The pig 100 comprises a support tube 202 and a tank 1. The case 1 is connected to the support pipe 202.
The axial direction of the support tube 202 coincides with the moving direction of the pig 100 (X direction shown in fig. 1), and the casing 1 is connected inside the support tube 202 and closes off one end opening of the support tube 202.
The pig 100 also includes a cleaning element 201. The cleaning member 201 surrounds the support tube 202 for cleaning impurities in the pipe.
Specifically, the cleaning element 201 is able to seal the gap between the support tube 202 and the pipeline during movement of the pig 100 within the pipeline.
The number of the cleaning members 201 may be one or more, for example, two, three, four, or the like.
Illustratively, the support tube 202 may have a cross-sectional shape that is circular, triangular, square, etc.
Through the above arrangement, in the process of moving the pig 100 in the pipeline, since the box 1 seals an opening at one end of the support pipe 202, the cleaning member 201 can seal a gap between the support pipe 202 and the pipeline, so that the pig 100 can seal the pipeline, and the pig 100 can move under the pressure difference between the mediums at the front and rear sides.
Thus, as the pig 100 moves within the pipeline, the cleaning element 201 contacts the pipeline, thereby removing impurities adhering to the pipeline from the pipeline (e.g., wax and other impurities adhering to the pipeline can be removed when the pig 100 moves within a crude oil pipeline, and water, oil, and other impurities within the pipeline can be removed when the pig 100 moves within a natural gas pipeline), thereby achieving the cleaning function of the pig 100 on the pipeline.
Illustratively, the clearance member 201 may be an abutment plate, an abutment block, or the like.
Illustratively, the cleaning member 201 may be made of rubber, silicone, or the like. The clearance piece 201 and the pipeline can be in interference fit, so that the pressure between the clearance piece 201 and the pipeline is increased, and the sealing effect of the clearance piece 201 on the clearance between the supporting piece and the pipeline and the cleaning effect on impurities on the pipeline are improved. And, the material of cleaing away piece 201 is rubber, silica gel etc. can also avoid cleaing away piece 201 and cause the damage to the pipeline, extension pipeline's life.
In some examples, as shown in fig. 1 and 2, the case 1 is located at a first end of the support tube 202 along an axial direction of the support tube 202, and partially extends out of the support tube 202, and the case 1 is provided with a connection flange 12, and the connection flange 12 is connected to an end face of the first end of the support tube 202.
In some embodiments, as shown in fig. 1 and 2, the pipe cleaning system further comprises a differential pressure sensor 3 and a processor.
The differential pressure sensor 3 is arranged on the pipe cleaner 100, and the differential pressure sensor 3 is used for detecting the pressure difference of the medium in the pipeline on the front side and the rear side of the pipe cleaner 100 in the process of moving the pipe cleaner 100 in the pipeline.
The processor is connected to the differential pressure sensor 3 and is configured to:
The pressure difference detected by the differential pressure sensor 3 is received.
If the number of times of the large change of the pressure difference at the same position of the pipeline is larger than or equal to the first preset number of times, judging that the position of the pipeline is deformed. The large change of the pressure difference means that the value of the pressure difference increased or decreased in the first preset time is greater than or equal to the first preset value.
It should be noted that, the first preset time refers to a time required for the pig 100 to move a certain distance, for example, a time for the pig 100 to move 0.1m is 0.1S, and the first preset time may be set to 0.1S, and a value of increasing or decreasing a pressure difference during the pipeline moving 0.1m is determined. The speed of the pressure difference increase or decrease when the pipe cleaning moves for a certain distance can be judged according to the magnitude of the value of the pressure difference increase or decrease in the first preset time, and the speed of the pressure difference increase is too high, so that the condition that the pipeline is abnormal is indicated.
The first preset value refers to a value that the pressure difference between the front side and the rear side of the pig 100 exceeds a normal fluctuation range (for example, 0-0.05 MPa) in the moving process, and is greater than the pressure difference between the front side and the rear side of the pig 100 when the pig 100 moves normally at the same position, and when the pressure difference between the front side and the rear side of the pig 100 is greater than the first preset value, it is indicated that the pressure difference changes greatly when the pig 100 moves to the position, and the pressure difference exceeds the normal fluctuation range, so that it is determined that impurities are accumulated in the pig or the pipe wall deforms.
Through the above arrangement, when the pig 100 moves to a certain position of the pipeline in the process of cleaning the pipeline for the first time, the pressure difference between the front side and the rear side of the pig 100 is greatly increased or reduced, which means that the resistance of the pig 100 at the position is greatly increased or reduced, that is, impurities exist at the position in the pipeline or the pipe wall is deformed at the position.
If the number of times of the large change in the pressure difference at the same position of the pipeline is greater than or equal to the first preset number of times, that is, the resistance applied to the pipeline pig 100 when moving to the position in the process of cleaning the pipeline later is still greatly increased or reduced, it indicates that the pipeline at the position is deformed, and the pipe wall of the pipeline is concave inwards or convex outwards, so that the inner diameter of the pipeline at the position is reduced or increased.
Specifically, taking the example that the pig 100 normally passes through the same location 3 times to remove the impurities at the location, the number of times the pig 100 passes through the same location is greater than or equal to 4 times (beyond the normal number), for example, 4 times, 5 times, 6 times, etc. (i.e., the first preset number of times may be 4 times, 5 times, 6 times, etc.), but when the pig 100 moves to the location, the pressure difference of the pig 100 still changes greatly, which means that the pressure difference caused by the impurities does not change greatly, but the pipe deforms.
In this way, whether the pipeline is deformed or not can be judged by detecting the pressure difference of the front side and the rear side of the pipe cleaner 100 through the pressure difference sensor 3, so that staff can clean the pipeline or maintain the pipeline according to specific conditions in subsequent work, and safe and efficient operation of the medium during pipeline transmission can be ensured.
It can be understood that in the above case, if the pressure difference at the same position of the pipe is greatly increased, it means that the pipe wall of the pipe is depressed inward, and if the pressure difference at the same position of the pipe is greatly reduced, it means that the pipe wall of the pipe is raised outward.
In some embodiments, the processor is further configured to:
if the number of times of the large change of the pressure difference at the same position of the pipeline is larger than or equal to 1 and smaller than a first preset number of times, the position of the pipeline is judged to be easy to accumulate impurities, wherein the first preset number of times is larger than 1.
Through the above arrangement, when the number of times of the large change of the pressure difference at the same position of the pipeline is greater than or equal to 1, it is indicated that the pressure difference between the front side and the rear side of the pig 100 is greatly increased or decreased when the pig 100 moves to the same position of the pipeline in the process of cleaning the pipeline for the first time, and it is indicated that the resistance to which the pig 100 is subjected is greatly increased or decreased, that is, impurities exist in the pipeline or deformation occurs in the pipe wall.
When the number of times of the large variation of the pressure difference at the same position of the pipe is smaller than the first preset number of times, it is explained that the resistance to which the pig 100 is moved to the position during the subsequent cleaning of the pipe gradually decreases, and the impurity is present at the position of the pipe and is gradually removed.
Specifically, taking the example that the pig 100 can normally pass through the same position for 3 times to remove the impurity at the position, the number of times that the pig 100 passes through the same position is less than 4 times (i.e. the number of times accords with the normal number), for example, 1 time, 2 times, 3 times, when the pig 100 moves to the position, the pressure difference of the pig 100 will not change greatly, which means that the pressure difference caused by the impurity changes greatly, and as the number of times that the pig 100 cleans the impurity increases, the impurity will gradually decrease, the pressure difference change will also gradually decrease, and after 1 time, 2 times or 3 times, the pressure difference will return to the normal range (i.e. the value of the pressure difference increases or decreases within the first preset time by a first preset value), which means that the impurity has been cleaned.
Therefore, the distribution position of impurities in the pipeline can be judged by detecting the pressure difference of the front side and the rear side of the pipe cleaner 100 through the pressure difference sensor, so that a worker can clean the pipeline or maintain the pipeline according to specific conditions in subsequent work, and the safe and efficient operation of the medium during the transmission through the pipeline is further ensured.
It should be noted that, in the process of cleaning impurities in a pipeline, when the number of times of great change of the pressure difference at the same position of the pipeline is greater, the impurities at the position are more difficult to clean, and the cleaning of the impurities at the position can be completed only by requiring more times of work of the pipe cleaner.
In some embodiments, as shown in fig. 1 and2, the pipe cleaning system further comprises a pressure sensor 2, the pressure sensor 2 being provided to the pig 100. The pressure sensor 2 is used to detect the pressure of the medium in the pipeline during the movement of the pig 100 in the pipeline.
The processor is connected to the pressure sensor 2 and is further configured to receive the pressure detected by the pressure sensor 2.
If the number of times of the large change of the pressure difference at the same position of the pipeline is larger than or equal to the first preset number of times and the number of times of the large change of the pressure is larger than or equal to the second preset number of times, judging that the position of the pipeline is deformed. The large change of the pressure means that the value of the pressure increased or decreased in the second preset time is greater than or equal to the second preset value.
The second preset time refers to a time required for the pig 100 to move a certain distance, for example, a time for the pig 100 to move 0.1m is 0.1S, and the second preset time may be set to 0.1S, which is a value for determining an increase or decrease in pressure during the pipe moving 0.1 m. The speed of pressure increase or decrease when the pipe cleaning moves for a certain distance can be judged according to the magnitude of the pressure increase or decrease value in the first preset time, and the speed of pressure increase is too high, so that the condition that the pipeline is abnormal is indicated.
The second preset value refers to a value that the pressure of the medium in the pipeline exceeds a normal fluctuation range (for example, 1.6MPa-12 MPa) in the moving process of the pipe cleaner 100, the second preset value is larger than the pressure of the medium when the pipe cleaner 100 moves normally at the same position, and when the pressure is larger than the first preset value, the pressure change is larger when the pipe cleaner 100 moves to the position, and the pressure exceeds the normal fluctuation range of the pressure of the medium in the pipeline, so that the situation that impurities are accumulated in the position or the pipe wall is deformed is determined.
The medium flowing in the pipe is from the high pressure side to the low pressure side, so that the pressure of the medium in the pipe gradually decreases as the medium flowing distance increases.
When the pressure of the medium in the pipe detected by the pressure sensor 2 is greatly increased or decreased, it is described that the accumulated medium or the pipe wall in the pipe is deformed, so that the cross-sectional area of the medium in the pipe is changed when the medium flows, and the pressure of the medium in the pipe is changed.
By the arrangement, on the basis that the number of times of the large change of the pressure difference at the same position of the pipeline is larger than or equal to the first preset number of times, if the pressure sensor 2 detects that the number of times of the large change of the pressure of the medium in the pipeline is larger than or equal to the second preset number of times, the deformation at the position of the pipeline is indicated.
Specifically, taking the example that the pig 100 normally passes through the same location 3 times to remove the impurities therein, the number of times the pig 100 passes through the same location is greater than or equal to 4 times (beyond the normal number), for example, 4 times, 5 times, 6 times, etc. (i.e., the second preset times may be 4 times, 5 times, 6 times, etc.), but the pressure of the medium therein still changes greatly, which means that the pressure is not changed greatly due to the impurities therein, but the pipe is deformed.
Therefore, compared with the method that whether the pipeline is deformed or not is judged only by the differential pressure sensor 3, when the differential pressure sensor 3 and the pressure sensor 2 are matched to jointly judge whether the pipeline is deformed or not, the error of the judgment result caused by the error of the data of the differential pressure sensor 3 can be avoided, so that the accuracy of judging whether the pipeline is deformed or not is improved, and a worker can know whether the pipeline is deformed or not more accurately, so that the safe and efficient operation of a medium in the process of pipeline transmission is ensured.
In some embodiments, if the number of times the pressure difference at the same position of the pipe varies greatly is greater than or equal to 1 and less than the first preset number of times, and the number of times the pressure varies greatly is greater than or equal to 1 and less than the second preset number of times, then it is determined that the position of the pipe is prone to accumulation of impurities.
By the above arrangement, when the number of times of the large variation of the pressure difference at the same position of the pipe is greater than or equal to 1 and less than the first preset number of times, it is explained that the pressure difference sensor 3 judges that the pipe is likely to accumulate the impurity at the position, and on this basis, when the number of times of the large variation of the pressure is greater than or equal to 1 and less than the second preset number of times, it can be determined that the impurity is likely to accumulate at the position of the pipe.
Therefore, compared with the method that whether the impurity is easily accumulated at a certain position in the pipeline is judged only by the differential pressure sensor 3, when the differential pressure sensor 3 and the pressure sensor 2 are matched to judge whether the impurity is easily accumulated at the same position of the pipeline, the error of the judging result caused by the error of the data of the differential pressure sensor 3 can be avoided, so that the accuracy of judging whether the impurity is easily accumulated at the same position of the pipeline is improved, and a worker can more accurately know whether the impurity is easily accumulated at the same position of the pipeline, so that the safe and efficient operation of a medium during the transmission through the pipeline is ensured.
On this basis, in some embodiments, as shown in fig. 1 and 2, the pipe cleaning system further comprises a temperature sensor 4, provided to the pig 100, the temperature sensor 4 being adapted to detect the temperature of the medium in the pipe.
The processor is connected to the temperature sensor 4 and is configured to:
The temperature detected by the temperature sensor 4 is received.
If the temperature of the medium at a certain position of the pipeline is less than or equal to the preset temperature, judging that the heat preservation layer at the position of the pipeline is broken.
It can be understood that as the medium flows in the pipeline, the temperature of the medium gradually decreases, and the process of decreasing the temperature of the medium is a continuous process, if the temperature of the medium at a certain position of the pipeline is greatly decreased, the heat loss speed of the medium at the position is too high.
The preset temperature refers to a temperature of the medium at a certain position of the pipe (e.g., 20 °, 30 °, 40 °, etc.) under normal conditions.
Through the arrangement, whether the temperature of the medium is normal or not can be judged through the temperature detected by the temperature sensor 4, if the temperature of the medium at a certain position of the pipeline is smaller than the preset temperature at the position, the heat loss at the position of the pipeline is too fast, namely the heat preservation layer of the pipeline is damaged, and the pipeline cannot be effectively preserved.
Therefore, staff can acquire the damage condition of the heat insulation layer of the pipeline through the temperature sensor 4, so that whether the heat insulation layer of the pipeline needs to be replaced or maintained is selected, and safe and efficient operation of the medium during transmission through the pipeline is further ensured.
Wherein, the heat preservation of pipeline can be the heat preservation rock wool, glass cotton, aerogel etc. of parcel on the periphery wall of pipeline.
During the movement of the pig 100 in the pipeline, the support tube 202 will rotate about its own axis relative to the pipeline, due to the pressure difference between the media on the front and rear sides and the friction of the cleaning element 201 against the inner wall of the pipeline.
In some embodiments, the pipe cleaning system further includes a gesture sensor provided to the pig 100 for detecting the angular velocity at which the support pipe 202 rotates about its own axis relative to the pipe.
The processor is coupled to the attitude sensor and is further configured to:
the angular velocity detected by the attitude sensor is received.
If the rotation speed is smaller than or equal to the preset angular speed at the same position of the pipeline and the number of times of large change of the pressure difference is larger than or equal to the first preset number of times, judging that the position of the pipeline is deformed.
It should be noted that the preset angular velocity refers to an angular velocity (for example, 1r/min, 2r/min, etc.) at which the pig 100 is normally at a certain position of the pipe, and the support pipe 202 rotates around its own axis relative to the pipe.
Through the above arrangement, on the basis that the number of times of the large variation of the pressure difference at the same position of the pipe is greater than or equal to the first preset number of times, if the attitude sensor detects that the angular velocity of the support pipe 202 rotating around the axis of the attitude sensor relative to the pipe is less than or equal to the preset angular velocity, it is indicated that the deformation occurs at the position of the pipe.
Specifically, when the pig 100 is affected by impurities or deformation of the pipe during movement, the resistance to movement of the pig 100 increases, thereby limiting rotation of the support tube 202 about its own axis, and when the angular velocity of rotation of the support tube 202 about its own axis relative to the pipe is less than or equal to the angular velocity of rotation of the support tube 202 about its own axis relative to the pipe under normal conditions, this indicates that impurities or deformation are present at that location of the pipe.
Therefore, compared with the method that whether the pipeline is deformed or not is judged only by the differential pressure sensor 3, when the differential pressure sensor 3 and the gesture sensor are matched to judge whether the pipeline is deformed or not, the error of the judgment result caused by the error of the data of the differential pressure sensor 3 can be avoided, so that the accuracy of judging whether the pipeline is deformed or not is improved, and a worker can know whether the pipeline is deformed or not more accurately, so that the safe and efficient operation of a medium during the transmission of the pipeline is ensured.
In some embodiments, if the number of times the pressure difference at the same position of the pipe varies greatly is greater than or equal to 1 and less than the first preset number of times, and the angular velocity at which the support pipe 202 rotates about its own axis relative to the pipe is greater than the preset angular velocity, then it is determined that the position of the pipe is prone to accumulation of impurities.
Through above-mentioned setting, compare in only judging through differential pressure sensor 3 whether a certain position in the pipeline piles up impurity easily, through differential pressure sensor 3 and attitude sensor's cooperation, can improve the accuracy of judging whether pipeline identity position piles up impurity easily to make the staff know whether pipeline identity position piles up impurity easily that can be more accurate, in order to guarantee the safe and efficient operation when the medium passes through pipeline transmission.
In some embodiments, the pipe cleaning system further comprises a memory electrically connected to the differential pressure sensor 3 for storing the pressure difference detected by the differential pressure sensor 3.
In this way, the pressure difference detected by the differential pressure sensor 3 can be stored through the memory, so that after the pipe cleaner 100 moves out of the pipeline, a worker can conveniently obtain the pressure difference detected by the differential pressure sensor 3, and then the processor is used for processing the pressure difference detected by the differential pressure sensor 3 to judge whether the pipeline is deformed. This allows the processor (e.g., cell phone, computer, etc.) to be located outside of the pipeline, thereby simplifying the construction of the pig 100. The pressure difference detected by the differential pressure sensor 3 can be stored, so that the subsequent use of the pressure difference detected by the differential pressure sensor 3 is facilitated.
In other embodiments, a processor (e.g., a CPU) may be disposed on the circuit board, and a worker may directly obtain data processed by the processor (i.e., determine whether the same position of the pipeline is deformed or is prone to accumulating impurities).
In some examples, as shown in FIG. 1, the pig 100 also includes a tracker 30 disposed within the support tube 202 for detecting the position of the pig 100.
Illustratively, the differential pressure sensor 3, the pressure sensor 2 and the temperature sensor 4 are disposed within the support tube such that the differential pressure sensor 3, the pressure sensor 2 and the temperature sensor 4 can directly contact the medium, thereby causing the differential pressure sensor 3 to detect a pressure difference, causing the pressure sensor 2 to detect a pressure, and causing the temperature sensor 4 to detect a temperature.
Illustratively, as shown in fig. 1 and 2, a differential pressure sensor 3, a pressure sensor 2 and a temperature sensor 4 are provided in the case 1.
In this way, the case 1 can provide protection for the differential pressure sensor 3, the pressure sensor 2, and the temperature sensor 4 from damage to the differential pressure sensor 3, the pressure sensor 2, and the temperature sensor 4 due to immersion in a medium.
In some embodiments, as shown in fig. 2, the case 1 is provided with a plurality of mounting holes 11.
The differential pressure sensor 3 includes a first body 31, a first detecting end 32, and a second detecting end 33, and the first detecting end 32 and the second detecting end 33 extend out of the case 1 through one of the mounting holes 11, respectively.
The pressure sensor 2 comprises a second body 22 and a third detection end 21, the third detection end 21 protruding out of the housing 1 through a mounting hole 11.
With the above arrangement, the first detection end 32, the second detection end 33 and the third detection end 21 can each extend out of the casing 1 through the mounting hole 11, so that the differential pressure sensor 3 can detect the pressure difference of the medium on opposite sides of the pig 100. And the pressure sensor 2 is enabled to detect the pressure of the medium on one side of the pig 100 in the direction of movement of the pig 100, thereby enabling a worker to acquire the distribution of impurities in the pipe and to determine whether the pipe is deformed.
In some embodiments, as shown in fig. 2, the box 1 comprises a first side wall 15 and a second side wall 16 arranged opposite each other in the direction of movement of the pig 100, the first side wall 15 and the second side wall 16 each being provided with a mounting hole 11.
Wherein the first detecting end 32 of the differential pressure sensor 3 extends out of the box 1 through a mounting hole 11 on the first side wall 15, and the second detecting end 33 extends out of the box 1 through a mounting hole 11 on the second side wall 16, so as to ensure that the differential pressure sensor 3 can detect the pressure difference of the medium on two opposite sides of the pipe cleaner 100.
In some examples, the temperature sensor 4 includes a third body 42 and a fourth sensing end 41, the fourth sensing end 41 protruding out of the case 1 through one of the mounting holes 11 to sense the temperature of the medium.
In some embodiments, as shown in FIG. 2, the temperature sensor 4 and the pressure sensor 2 are located on the same side of the differential pressure sensor 3 in the radial direction of the support tube 202. And the temperature sensor 4 and the pressure sensor 2 are arranged in sequence along the axial direction of the support pipe 202.
Through the arrangement, compared with the pressure sensor 2 or the temperature sensor 4 being located at one side of the differential pressure sensor 3 in the axial direction of the support tube 202, when the pressure sensor 2 and the temperature sensor 4 are located at one side of the differential pressure sensor 3 in the radial direction of the support tube 202, the pressure sensor 2, the temperature sensor 4 and the differential pressure sensor 3 can be prevented from occupying larger space in the axial direction of the support tube 202, and meanwhile, the temperature sensor 4 and the pressure sensor 2 are sequentially arranged along the axial direction of the support tube 202, so that the pressure sensor 2, the temperature sensor 4 and the differential pressure sensor 3 can be prevented from occupying larger space in the radial direction of the support tube 202, the integration level of the pressure sensor 2, the temperature sensor 4 and the differential pressure sensor 3 is improved, and the space arrangement of the pressure sensor 2, the temperature sensor 4 and the differential pressure sensor 3 is facilitated.
It can be understood that in the above case, when the pressure sensor 2, the temperature sensor 4, and the differential pressure sensor 3 are all provided in the case, the case 1 can be prevented from being oversized in the axial direction of the support pipe 202 or in the radial direction of the support pipe 202, thereby facilitating the spatial arrangement of the case 1.
In some embodiments, the pig 100 further includes a circuit board 5, with the memory being provided to the circuit board 5. The pressure sensor 2, the temperature sensor 4 and the differential pressure sensor 3 are all connected with a circuit board to store the pressure detected by the pressure sensor 2, the pressure difference detected by the differential pressure sensor 3 and the temperature detected by the temperature sensor 4 in a memory.
With the above arrangement, the pressure detected by the pressure sensor 2, the pressure difference detected by the differential pressure sensor 3, and the temperature detected by the temperature sensor 4 can be transmitted to the memory through the circuit board 5, and then stored in the memory to save the pressure detected by the pressure sensor 2, the pressure difference detected by the differential pressure sensor 3, and the temperature detected by the temperature sensor 4.
In some embodiments, as shown in fig. 2, the thickness direction of the circuit board 5 is perpendicular to the axial direction of the support tube 202, and the pressure sensor 2, the temperature sensor 4, and the differential pressure sensor 3 are all one side in the thickness direction of the circuit board 5.
Through the above-mentioned setting, compare in the thickness direction of circuit board 5 and the axial unanimity of stay tube 202, the thickness direction of circuit board 5 is perpendicular to the axial of stay tube 202, when pressure sensor 2, temperature sensor 4 and differential pressure sensor 3 are equal one side in the thickness direction of circuit board 5, along the thickness direction of circuit board, the space that circuit board 5, differential pressure sensor 3, pressure sensor 2 and temperature sensor 4 occupy is less, so can improve circuit board 5, differential pressure sensor 3, pressure sensor 2 and temperature sensor 4's integrated level, make things convenient for the space setting of circuit board 5, differential pressure sensor 3, pressure sensor 2 and temperature sensor 4.
In some examples, as shown in fig. 2, the circuit board 5 is disposed within the case 1, such that protection of the circuit board 5 can be provided by the case 1.
The foregoing is merely illustrative embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily think about variations or substitutions within the technical scope of the present application, and the application should be covered. Therefore, the protection scope of the application is subject to the protection scope of the claims.
