As shown in fig. 1, the present embodiment provides a gas pipeline pressure detector with an alarm structure, which comprises a gas pressure detector main body 1, wherein a detector interface 11 of the gas pressure detector main body 1 is connected with a detection container 13 through a first connecting pipeline 12, an input interface 131 of the detection container 13 is connected with a connecting interface 15 through a second connecting pipeline 17, and the connecting interface 15 is used for being connected with the gas pipeline interface;
The detection container 13 is internally provided with a detection device, the surface of the detection container 13 is provided with an alarm device 18, and the alarm device 18 is in signal connection with the detection device.
During detection, the gas in the gas pipeline enters the detection container 13 and the gas pressure detector main body 1 through the second connecting pipeline 17 through the connecting interface 15 and is detected by the gas pressure detector main body 1 and the detection device in the detection container 13, the gas pressure value is displayed by the gas pressure detector main body 1, the detection device in the detection container 13 can recheck the detection result of the gas pressure detector main body 1, the detection reliability of the detector is ensured, the threshold value of the alarm device 18 is further preset, and when the detected pressure exceeds the preset threshold value, the indication function is generated through the alarm device 18, so that the warning effect is achieved.
As shown in fig. 2, the detection device includes a gas pressure sensor 133 fixed inside the detection container 13, a protective housing 134 is covered outside the gas pressure sensor 133, and a probe of the gas pressure sensor 133 penetrates through the protective housing 134 and extends into a cavity of the detection container 13. The first connection pipe 12 is connected to the output port 132 of the detection container 13, and the air pressure sensor 133 detects the air pressure in the detection container 13 and sends an alarm signal to the alarm device 18 when the air pressure exceeds a threshold value.
Optionally, the alarm device 18 includes an indicator light, a buzzer, and a display. In this embodiment, the alarm device 18 is an indicator lamp, and when the detected result of the air pressure sensor 133 exceeds the threshold value, the air pressure sensor 133 flashes to alert the operator, and the buzzer can be used to generate an audible alarm.
Further, the first connecting pipe 12 and the second connecting pipe 17 are respectively provided with a second manual valve 16 and a first manual valve 14, and when the second manual valve 16 and the first manual valve 14 are in a closed state, the detection container 13 forms a closed container. Meanwhile, the second manual valve 16 can be closed when the gas pressure detector main body 1 is not needed to detect or in the subsequent ignition process, so that the gas pressure detector main body 1 is prevented from being damaged, but in this way, a small amount of gas overflows.
