用于压缩机的排气管组件、壳体组件、压缩机和制冷装置Discharge pipe assemblies, housing assemblies, compressors and refrigeration units for compressors

技术领域technical field

本发明涉及压缩机技术领域，尤其是涉及一种用于压缩机的排气管组件、壳体组件、压缩机和制冷装置。The present invention relates to the technical field of compressors, and in particular, to an exhaust pipe assembly, a casing assembly, a compressor and a refrigeration device for a compressor.

背景技术Background technique

在目前普遍使用的制冷装置中，压缩机从上一回运行后停机到可以再次启动时，压缩机的吸气侧与排气侧的压力差必须要达到某个要求的范围内才可以重新启动，特别是对于滚动转子式压缩机来说，该压力差必须达到一个较小的数值例如1kgf/cm2以内，否则将无法启动再次启动压缩机，从而无法实现快速启动功能。In the currently commonly used refrigeration device, when the compressor is stopped after the last operation and can be restarted, the pressure difference between the suction side and the exhaust side of the compressor must reach a certain required range before restarting. , especially for rolling rotor compressors, the pressure difference must reach a small value such as within 1kgf/cm2, otherwise it will not be able to start the compressor again, so that the fast start function cannot be achieved.

同时，压缩机停机后，在部分条件下，系统中的冷媒会通过排气管进入压缩机内部，使压缩机内冷媒发生沉积，从而使压缩机底部油池溶解过多冷媒导致润滑油粘度下降，当压缩机再次启动时，压缩机内部的润滑油粘度下降可能导致异常磨损，降低了压缩机的可靠性。At the same time, after the compressor is stopped, under some conditions, the refrigerant in the system will enter the compressor through the exhaust pipe, causing the refrigerant in the compressor to deposit, so that the oil pool at the bottom of the compressor dissolves too much refrigerant and causes the viscosity of the lubricating oil to drop. , When the compressor starts again, the viscosity of the lubricating oil inside the compressor decreases, which may cause abnormal wear and reduce the reliability of the compressor.

下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能理解为对本发明的限制。The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, only used to explain the present invention, and should not be construed as a limitation of the present invention.

下面参考附图描述根据本发明实施例的用于压缩机1000的排气管组件100。其中，排气管组件100可以设置在压缩机1000的壳体30上。Theexhaust pipe assembly 100 for thecompressor 1000 according to the embodiment of the present invention will be described below with reference to the accompanying drawings. Wherein, theexhaust pipe assembly 100 may be provided on the casing 30 of thecompressor 1000 .

根据本发明第一方面实施例的用于压缩机1000的排气管组件100，包括：排气管20和单向阀10。Theexhaust pipe assembly 100 for thecompressor 1000 according to the embodiment of the first aspect of the present invention includes: an exhaust pipe 20 and a one-way valve 10 .

具体地，参照图1和图2，排气管20内限定出排气通道20a，排气通道20a具有进气口22a和出气口21a。例如，在图1和图2的示例中，进气口22a形成在排气通道20a的下端，出气口21a形成在排气通道20a的上端。在压缩机1000运行时，压缩机1000可以通过排气管20向外排气。Specifically, referring to FIGS. 1 and 2 , anexhaust passage 20a is defined in the exhaust pipe 20, and theexhaust passage 20a has anair inlet 22a and anair outlet 21a. For example, in the example of FIGS. 1 and 2 , theair inlet 22a is formed at the lower end of theexhaust passage 20a, and theair outlet 21a is formed at the upper end of theexhaust passage 20a. When thecompressor 1000 is operating, thecompressor 1000 may discharge air to the outside through the discharge pipe 20 .

在本发明的描述中，需要理解的是，术语“中心”、“厚度”、“上”、“下”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。In the description of the present invention, it should be understood that the orientations or positional relationships indicated by the terms "center", "thickness", "upper", "lower", "inner", "outer", etc. are based on those shown in the accompanying drawings The orientation or positional relationship is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

单向阀10设在排气通道20a内，单向阀10在从进气口22a到出气口21a的方向上单向导通。The one-way valve 10 is provided in theexhaust passage 20a, and the one-way valve 10 conducts one-way conduction in the direction from theair inlet 22a to theair outlet 21a.

由此，在压缩机1000工作时，单向阀10导通，排气管20的进气口22a和出气口21a连通，换热介质(例如冷媒等)经排气管20排至压缩机1000外，实现制冷装置的正常循环。在压缩机1000停止工作时，单向阀10断开，排气管20的进气口22a和出气口21a不再连通，此时，排气管20内的换热介质无法进入压缩机1000内部，利于压缩机1000快速地实现压力平衡，满足快速重启的要求。同时，可以避免压缩机1000内的冷媒发生沉积，从而可以避免压缩机1000底部油池溶解过多冷媒导致的润滑油粘度下降，进而可以在压缩机1000再次启动时，避免压缩机1000内部的润滑油粘度下降可能导致的异常磨损，提高了压缩机1000的可靠性。Therefore, when thecompressor 1000 is operating, thecheck valve 10 is turned on, theair inlet 22a and theair outlet 21a of the exhaust pipe 20 are connected, and the heat exchange medium (eg, refrigerant, etc.) is discharged to thecompressor 1000 through the exhaust pipe 20 In addition, the normal circulation of the refrigeration device is realized. When thecompressor 1000 stops working, the one-way valve 10 is disconnected, and theair inlet 22a and theair outlet 21a of the exhaust pipe 20 are no longer connected. At this time, the heat exchange medium in the exhaust pipe 20 cannot enter the interior of thecompressor 1000. , which is beneficial for thecompressor 1000 to quickly achieve pressure balance and meet the requirements of rapid restart. At the same time, the deposition of the refrigerant in thecompressor 1000 can be avoided, so that the viscosity of the lubricating oil caused by too much refrigerant being dissolved in the oil pool at the bottom of thecompressor 1000 can be avoided, and the lubrication inside thecompressor 1000 can be avoided when thecompressor 1000 is restarted. Abnormal wear that may result from a drop in oil viscosity increases the reliability of thecompressor 1000 .

根据本发明实施例的用于压缩机1000的排气管组件100，通过在排气管20内设置单向阀10，使单向阀10从进气口22a到出气口21a单向导通，由此，在压缩机1000处于工作状态时，换热介质能够正常循环，且在压缩机1000停止工作后，排气管20内的换热介质不会逆流，有利于压缩机1000快速地实现压力平衡，满足快速重启的要求。同时，可以避免压缩机1000内的冷媒发生沉积，避免异常磨损，有利于提高压缩机1000的可靠性。此外，还可以减小热量损失，提高制冷装置的运行效率。According to theexhaust pipe assembly 100 for thecompressor 1000 according to the embodiment of the present invention, by arranging the one-way valve 10 in the exhaust pipe 20, the one-way valve 10 is unidirectionally conducted from theair inlet 22a to theair outlet 21a. Therefore, when thecompressor 1000 is in the working state, the heat exchange medium can circulate normally, and after thecompressor 1000 stops working, the heat exchange medium in the exhaust pipe 20 will not flow backward, which is beneficial for thecompressor 1000 to quickly achieve pressure balance , to meet the requirements of fast restart. At the same time, deposition of the refrigerant in thecompressor 1000 can be avoided, abnormal wear can be avoided, and the reliability of thecompressor 1000 can be improved.

In this way, the connection of thefirst pipe section 21 and thesecond pipe section 22 can be easily realized, which makes the assembly of theexhaust pipe assembly 100 easier and easier to install and use.

根据本发明的一些实施例，第二管段22的内壁上设有朝向第二管段22的外壁凹入的凹槽22b，单向阀10固定在凹槽22b内。可选地，凹槽22b可以形成为环形。由此，可以将单向阀10方便且牢靠地安装在第二管段22内，降低了单向阀10的装配难度，提高了安装效率。According to some embodiments of the present invention, the inner wall of thesecond pipe section 22 is provided with agroove 22b concave toward the outer wall of thesecond pipe section 22, and the one-way valve 10 is fixed in thegroove 22b. Alternatively, thegroove 22b may be formed in a ring shape. Therefore, the one-way valve 10 can be conveniently and securely installed in thesecond pipe section 22, which reduces the assembly difficulty of the one-way valve 10 and improves the installation efficiency.

在本发明的一些实施例中，第二管段22包括彼此相连的主体段221和连接段222，其中，连接段222设在主体段221的上方。连接段222与第一管段21相连，单向阀10设在主体段221内，主体段221的横截面积大于连接段222的横截面积。由此，可以进一步地降低单向阀10的装配难度，提高安装效率。In some embodiments of the present invention, thesecond pipe section 22 includes amain section 221 and a connectingsection 222 that are connected to each other, wherein the connectingsection 222 is provided above themain section 221 . The connectingsection 222 is connected to thefirst pipe section 21 , the one-way valve 10 is arranged in themain section 221 , and the cross-sectional area of themain section 221 is larger than that of the connectingsection 222 . Therefore, the assembly difficulty of thecheck valve 10 can be further reduced, and the installation efficiency can be improved.

根据本发明的一些实施例，单向阀10包括：阀座1、限位器2、阀芯3和弹性元件4。其中，阀座1与排气管20的内壁相连，且阀座1将排气通道20a分隔为第一通道201和第二通道202，第一通道201与进气口22a连通，第二通道202与出气口21a连通，阀座1上设有贯通的入口11。参照图4-图9，入口11形成为在阀座1的厚度方向上贯穿阀座1的贯通口。According to some embodiments of the present invention, the one-way valve 10 includes: avalve seat 1 , alimiter 2 , avalve core 3 and anelastic element 4 . Thevalve seat 1 is connected to the inner wall of the exhaust pipe 20, and thevalve seat 1 divides theexhaust passage 20a into afirst passage 201 and asecond passage 202. Thefirst passage 201 communicates with theair inlet 22a, and thesecond passage 202 In communication with theair outlet 21a, thevalve seat 1 is provided with a throughinlet 11. 4 to 9 , theinlet 11 is formed as a through port penetrating thevalve seat 1 in the thickness direction of thevalve seat 1 .

限位器2与阀座1相连，限位器2与阀座1之间限定出阀腔2a，入口11与阀腔2a连通，限位器2上设有与阀腔2a连通的出口21。阀芯3设在阀腔2a内且在第一位置和第二位置之间可移动，其中，在第一位置时，阀芯3关闭入口11。在第二位置时，阀芯3打开入口11以使第一通道201与第二通道202连通，且在第二位置时，阀芯3与限位器2止抵配合。在第二位置时，由于阀芯3与限位器2止抵配合，从而可以通过限位器2限制阀芯3继续运动。弹性元件4连接在阀芯3和限位器2之间以常驱动阀芯3关闭入口11。Thelimiter 2 is connected with thevalve seat 1, avalve cavity 2a is defined between thelimiter 2 and thevalve seat 1, theinlet 11 is communicated with thevalve cavity 2a, and thelimiter 2 is provided with anoutlet 21 which communicates with thevalve cavity 2a. Thevalve core 3 is provided in thevalve cavity 2a and is movable between a first position and a second position, wherein thevalve core 3 closes theinlet 11 in the first position. In the second position, thevalve core 3 opens theinlet 11 so that thefirst channel 201 and thesecond channel 202 communicate with each other, and in the second position, thevalve core 3 is abutted against thelimiter 2 . In the second position, thevalve core 3 can be restricted from continuing to move by thestopper 2 because thevalve core 3 is abutted against thelimiter 2 . Theelastic element 4 is connected between thevalve core 3 and thelimiter 2 to constantly drive thevalve core 3 to close theinlet 11 .

其中，在第一位置时，阀芯3关闭入口11，此时阀芯3的入口11和出口21不连通，从而第一通道201和第二通道202不连通，此时，换热介质无法从排气管20的进气口22a流向出气口21a。在第二位置时，阀芯3打开入口11，阀芯3的入口11和出口21连通，从而第一通道201和第二通道202连通，此时，换热介质可以从排气管20的进气口22a流向出气口21a。Among them, in the first position, thevalve core 3 closes theinlet 11, at this time theinlet 11 and theoutlet 21 of thevalve core 3 are not connected, so thefirst channel 201 and thesecond channel 202 are not connected, at this time, the heat exchange medium cannot flow from theThe air inlet 22a of the exhaust pipe 20 flows to theair outlet 21a. In the second position, thevalve core 3 opens theinlet 11, and theinlet 11 and theoutlet 21 of thevalve core 3 are connected, so that thefirst channel 201 and thesecond channel 202 are connected. Theair port 22a flows toward theair outlet 21a.

由此，在该排气管组件100应用于制冷装置时，在制冷装置停止工作时，压缩机1000停机，阀芯3下部与阀芯3上部的气体压差力小于弹性元件4的弹力，此时阀芯3在弹性元件4的弹性压力作用下移动至第一位置以关闭入口11，排气通道20a的第一通道201和第二通道202互不连通，排气管20内的换热介质无法流向压缩机1000内部，由此，有利于压缩机1000快速地实现压力平衡，满足快速重启的要求。同时，可以避免压缩机1000内的冷媒发生沉积，避免异常磨损，有利于提高压缩机1000的可靠性。Therefore, when theexhaust pipe assembly 100 is applied to a refrigeration device, when the refrigeration device stops working, thecompressor 1000 is stopped, and the gas pressure differential force between the lower part of thevalve core 3 and the upper part of thevalve core 3 is smaller than the elastic force of theelastic element 4, so this When thevalve core 3 moves to the first position under the elastic pressure of theelastic element 4 to close theinlet 11, thefirst channel 201 and thesecond channel 202 of theexhaust channel 20a are not communicated with each other, and the heat exchange medium in the exhaust pipe 20 It cannot flow into the interior of thecompressor 1000 , thus, it is beneficial for thecompressor 1000 to quickly achieve pressure balance and meet the requirement for rapid restart. At the same time, deposition of the refrigerant in thecompressor 1000 can be avoided, abnormal wear can be avoided, and the reliability of thecompressor 1000 can be improved.

在压缩机1000工作时，阀芯3下端的气体压力较大，当阀芯3下部与阀芯3上部的气体压差力大于弹性元件4的弹力(忽略阀芯3及弹性元件4的重力)时，弹性元件4被压缩，第二通道202内的压力推动阀芯3移动至第二位置以打开阀座1上的入口11，且在第二位置时阀芯3与限位器2止抵配合以限制阀芯3继续朝向远离入口11的方向移动，起到对阀芯3的限位作用，第一通道201和第二通道202连通，进入排气通道20a内的换热介质通过阀座1上的入口11流向出气口21a，从排气管20排出，使换热介质能够正常循环，进而使得制冷装置可以正常工作。When thecompressor 1000 is working, the gas pressure at the lower end of thevalve core 3 is relatively large. When the gas pressure difference between the lower part of thevalve core 3 and the upper part of thevalve core 3 is greater than the elastic force of the elastic element 4 (ignoring the gravity of thevalve core 3 and the elastic element 4) When theelastic element 4 is compressed, the pressure in thesecond passage 202 pushes thevalve core 3 to move to the second position to open theinlet 11 on thevalve seat 1, and thevalve core 3 stops against thelimiter 2 in the second position Thefirst channel 201 is communicated with thesecond channel 202, and the heat exchange medium entering theexhaust channel 20a passes through the valve seat. Theinlet 11 on the 1 flows to theair outlet 21a, and is discharged from the exhaust pipe 20, so that the heat exchange medium can circulate normally, so that the refrigeration device can work normally.

同时，由于本申请中的单向阀10通过弹性元件4驱动阀芯3运动，属于全机械式控制，结构简单，体积小且稳定性和可靠性高。At the same time, because the one-way valve 10 in the present application drives thevalve core 3 to move through theelastic element 4, it is fully mechanically controlled, with a simple structure, small size, and high stability and reliability.

根据本发明的一些实施例，阀芯3包括：阀块31和阀片32，弹性元件4套设在阀块31外。可选地，弹性元件4可以为弹簧。阀片32设在阀块31的邻近阀座1一端(例如，图5中的下端)，在第一位置时，阀片32关闭入口11，在第二位置时，阀片32打开入口11。由此，通过将阀芯3设置成包括阀块31和阀片32的结构，使得阀芯3的结构简单，且方便阀芯3打开和关闭入口11。According to some embodiments of the present invention, thevalve core 3 includes: avalve block 31 and avalve plate 32 , and theelastic element 4 is sleeved outside thevalve block 31 . Alternatively, theelastic element 4 may be a spring. Thevalve plate 32 is provided at one end of thevalve block 31 adjacent to the valve seat 1 (eg, the lower end in FIG. 5 ). Therefore, by arranging thevalve core 3 into a structure including thevalve block 31 and thevalve sheet 32 , the structure of thevalve core 3 is simple, and it is convenient for thevalve core 3 to open and close theinlet 11 .

在本发明的一些实施例中，阀片32形成为平板状或片状。由此，可以减小单向阀10的整体体积，减小单向阀10的占用空间，便于单向阀10的安装使用。In some embodiments of the present invention, thevalve plate 32 is formed in the shape of a flat plate or a sheet. Therefore, the overall volume of the one-way valve 10 can be reduced, the occupied space of the one-way valve 10 can be reduced, and the installation and use of the one-way valve 10 can be facilitated.

可选地，阀片32的形状可以与入口11的形状相适配。例如，当入口11形成为圆形孔时，阀片32可以形成为圆形。结构简单，加工方便，且便于实现阀片32对入口11的密封。Optionally, the shape of thevalve plate 32 may be adapted to the shape of theinlet 11 . For example, when theinlet 11 is formed as a circular hole, thevalve plate 32 may be formed in a circular shape. The structure is simple, the processing is convenient, and the sealing of thevalve plate 32 to theinlet 11 is facilitated.

根据本发明的一些实施例，阀座1上设有凸起部12，凸起部12环绕在入口11的外周，在第一位置时，阀片32与凸起部12止抵配合以形成面面密封或线线密封。这样，可保证阀片32与阀座1具有较大的接触面积，使得二者有效密封，防止换热介质逆流。According to some embodiments of the present invention, thevalve seat 1 is provided with a raisedportion 12, and the raisedportion 12 surrounds the outer circumference of theinlet 11. In the first position, thevalve plate 32 is abutted against the raisedportion 12 to form a surface Face seal or line seal. In this way, it can be ensured that thevalve plate 32 and thevalve seat 1 have a larger contact area, so that the two are effectively sealed and the heat exchange medium is prevented from flowing back.

例如，在本发明的一些实施例中，参照图9和图10，凸起部12的外周面形成为弧形面，此时凸起部12与阀片32之间形成线线密封。具体地，当凸起部12形成为圆环形时，凸起部12与阀片32之间的配合处形成为圆形。For example, in some embodiments of the present invention, referring to FIG. 9 and FIG. 10 , the outer peripheral surface of theconvex portion 12 is formed as an arc surface, and a line seal is formed between theconvex portion 12 and thevalve plate 32 at this time. Specifically, when the protrudingportion 12 is formed in a circular shape, the fitting between the protrudingportion 12 and thevalve plate 32 is formed in a circular shape.

又如，在本发明的另一些实施例中，参照图11，凸起部12的外周面包括平坦面，且平坦面与阀片32止抵接触。此时凸起部12与阀片32之间形成面面密封。可选地，平坦面的宽度B满足：0.1mm≤B≤0.8mm。例如，B可以进一步满足：B＝0.1mm、B＝0.2mm、B＝0.3mm、B＝0.4mm、B＝0.5mm、B＝0.6mm、B＝0.7mm、B＝0.8mm等。由此，可以提高阀片32与阀座1的密封效果。For another example, in other embodiments of the present invention, referring to FIG. 11 , the outer peripheral surface of the protrudingportion 12 includes a flat surface, and the flat surface is in abutting contact with thevalve plate 32 . At this time, a surface-to-surface seal is formed between theconvex portion 12 and thevalve plate 32 . Optionally, the width B of the flat surface satisfies: 0.1mm≤B≤0.8mm. For example, B may further satisfy: B=0.1 mm, B=0.2 mm, B=0.3 mm, B=0.4 mm, B=0.5 mm, B=0.6 mm, B=0.7 mm, B=0.8 mm, and the like. Thereby, the sealing effect between thevalve plate 32 and thevalve seat 1 can be improved.

可以理解的是，平坦面的宽度为平坦面的外端与内端之间的间距。例如，当平坦面形成为环形面时，平坦面的宽度为平坦面的外径与内径之差。It can be understood that the width of the flat surface is the distance between the outer end and the inner end of the flat surface. For example, when the flat surface is formed as an annular surface, the width of the flat surface is the difference between the outer diameter and the inner diameter of the flat surface.

根据本发明的一些实施例，凸起部12与阀片32的配合处与阀片32的外端之间的最小距离d满足：d≥0.5mm。例如，d可以进一步满足：d＝0.6mm、d＝0.7mm、d＝0.8mm等。由此，可以提高阀片32与阀座1的密封效果。According to some embodiments of the present invention, the minimum distance d between the fitting position of the protrudingportion 12 and thevalve plate 32 and the outer end of thevalve plate 32 satisfies: d≧0.5mm. For example, d may further satisfy: d=0.6mm, d=0.7mm, d=0.8mm, and the like. Thereby, the sealing effect between thevalve plate 32 and thevalve seat 1 can be improved.

根据本发明的一些实施例，阀片32通过螺钉5或铆钉6与阀块31相连。例如，在图5和图6的示例中，阀片32通过螺钉5与阀块31相连。在图7的示例中，阀片32通过铆钉6与阀块31相连。结构简单，且连接可靠。According to some embodiments of the present invention, thevalve plate 32 is connected to thevalve block 31 by means ofscrews 5 or rivets 6 . For example, in the example of FIG. 5 and FIG. 6 , thevalve plate 32 is connected to thevalve block 31 through thescrew 5 . In the example of FIG. 7 , thevalve plate 32 is connected to thevalve block 31 by therivet 6 . The structure is simple and the connection is reliable.

具体地，参照图12，阀片32上形成有贯通的安装孔321，螺钉5或铆钉6可以穿过安装孔321与阀片32连接。Specifically, referring to FIG. 12 , a through mountinghole 321 is formed on thevalve plate 32 , and thescrew 5 or therivet 6 can be connected to thevalve plate 32 through the mountinghole 321 .

根据本发明的一些实施例，阀块31包括彼此相连的安装段311和导向段312，弹性元件4套设在安装段311上，限位器2上设有导向孔22，导向段312适于伸入导向孔22内与导向孔22配合，安装段311的横截面大于导向孔22的横截面。由此，阀芯3在移动过程中，通过导向段312与导向孔22配合，可以对阀芯3进行导向，减小阀芯3移动过程中的摇摆及窜动，降低气体流动损失。同时，由于安装段311的横截面大于导向孔22的横截面，在阀芯3移动至第二位置时，安装段311可以与限位器2的内壁面止抵配合以限制阀芯3继续移动。According to some embodiments of the present invention, thevalve block 31 includes aninstallation section 311 and aguide section 312 connected to each other, theelastic element 4 is sleeved on theinstallation section 311, thelimiter 2 is provided with aguide hole 22, and theguide section 312 is suitable for Protruding into theguide hole 22 to cooperate with theguide hole 22 , the cross section of the mountingsection 311 is larger than the cross section of theguide hole 22 . Therefore, during the movement of thevalve core 3, theguide section 312 cooperates with theguide hole 22 to guide thevalve core 3, thereby reducing the swaying and turbulence of thevalve core 3 during the movement process, and reducing the gas flow loss. At the same time, since the cross section of theinstallation section 311 is larger than the cross section of theguide hole 22 , when thevalve core 3 moves to the second position, theinstallation section 311 can abut against the inner wall surface of thestopper 2 to limit thevalve core 3 to continue to move. .

可选地，在阀芯3位于第一位置时，导向段312的上端伸出导向孔22，由此，可以保证导向效果。Optionally, when thevalve core 3 is in the first position, the upper end of theguide section 312 protrudes out of theguide hole 22 , so that the guiding effect can be ensured.

根据本发明的一些实施例，导向孔22与导向段312之间的配合间隙H₁满足：0.1mm≤H₁≤0.5mm。可以理解的是，当导向孔22与导向段312之间的配合间隙过小时，导向段312进入导向孔22时容易卡死，从而引起单向阀10失效，若导向孔22与导向段312之间的配合间隙过大，则导向作用不明显，导向处进入限位孔时摇摆及窜动明显，一方面会引起异常噪音，另一方面气体流动损失较大。在导向孔22与导向段312之间的配合间隙H₁满足：0.1mm≤H₁≤0.5mm时，导向作用最优且不会引起单向阀10动作时的异常噪音。According to some embodiments of the present invention, the fitting clearance H₁ between theguide hole 22 and theguide segment 312 satisfies: 0.1 mm≦H₁ ≦0.5 mm. It can be understood that when the fitting clearance between theguide hole 22 and theguide section 312 is too small, theguide section 312 is likely to be stuck when entering theguide hole 22, thereby causing thecheck valve 10 to fail. If the matching gap between them is too large, the guiding effect will not be obvious, and the swing and swaying will be obvious when the guide enters the limit hole. On the one hand, it will cause abnormal noise, and on the other hand, the gas flow loss will be large. When the fitting clearance H₁ between theguide hole 22 and theguide segment 312 satisfies: 0.1 mm≤H₁ ≤0.5 mm, the guiding effect is optimal and the abnormal noise when thecheck valve 10 is actuated will not be caused.

根据本发明的一些实施例，弹性元件4与安装段311过盈配合。例如，弹性元件4与安装段311之间的配合间隙H2满足：0＜H2≤0.4mm。在本发明的一些实施中，安装段311的外径为内径为D1，弹性元件4的安装内径为D2，H2＝D1-D2。由此，可保证弹性元件4与安装段311的过盈配合，利于弹性元件4的安装的同时，减小弹性元件4的变形。According to some embodiments of the present invention, theelastic element 4 is in an interference fit with the mountingsection 311 . For example, the fitting gap H2 between theelastic element 4 and the mountingsection 311 satisfies: 0<H2≤0.4mm. In some implementations of the present invention, the outer diameter of theinstallation section 311 is the inner diameter D1, the installation inner diameter of theelastic element 4 is D2, and H2=D1-D2. In this way, the interference fit between theelastic element 4 and the mountingsection 311 can be ensured, which facilitates the installation of theelastic element 4 and reduces the deformation of theelastic element 4 .

根据本发明的一些实施例，导向段312的外周面包括两个沿导向段312的轴向延伸平面313，两个平面313相对于导向段312的中心轴线对称。由此，在装配过程中，有利于螺钉5的固定拧紧。According to some embodiments of the present invention, the outer peripheral surface of theguide section 312 includes two axially extendingplanes 313 along theguide section 312 , and the twoplanes 313 are symmetrical with respect to the central axis of theguide section 312 . Therefore, during the assembly process, the fixing and tightening of thescrew 5 is facilitated.

根据本发明的一些实施例，限位器2包括：限位板23、侧板24和安装板25。侧板24连接在限位板23的外周，安装板25设在侧板24上，且安装板25适于与阀座1相连。结构简单，加工方便。According to some embodiments of the present invention, thestopper 2 includes: astopper plate 23 , aside plate 24 and a mountingplate 25 . Theside plate 24 is connected to the outer periphery of the limitingplate 23 , the mountingplate 25 is provided on theside plate 24 , and the mountingplate 25 is suitable for being connected with thevalve seat 1 .

That is to say, the limitingplate 23 is provided with one ormore outlets 21 . Theoutlet 21 may be formed as a circular hole, a waist-shaped hole or a special-shaped hole. In the description of the present invention, "plurality" means two or more. Thereby, the vortex formed by the airflow in therestrictor 2 can be reduced, thereby reducing the flow loss.

根据本发明的一些实施例，侧板24上设有至少一个出口21。也就是说，侧板24上设有一个或者多个出口21。由此，在限位板23及侧板24上均设置有出口21，能明显减小气流在限位器2内形成的漩涡，从而减小流动损失。According to some embodiments of the present invention, theside plate 24 is provided with at least oneoutlet 21 . That is, theside plate 24 is provided with one ormore outlets 21 . Therefore, theoutlet 21 is provided on both the limitingplate 23 and theside plate 24, which can significantly reduce the vortex formed by the airflow in the limitingdevice 2, thereby reducing the flow loss.

可选地，在本发明的一些实施例中，限位板23上设有三个出口21，侧板24上设有三个出口21。其中，限位板23上的三个出口21在导向孔22的周向上间隔开设置，侧板24上的三个出口21在侧板24的周向上间隔设置。由此，可以明显减小气流在限位器2内形成的漩涡，从而减小流动损失。Optionally, in some embodiments of the present invention, the limitingplate 23 is provided with threeoutlets 21 , and theside plate 24 is provided with threeoutlets 21 . The threeoutlets 21 on the limitingplate 23 are arranged at intervals in the circumferential direction of theguide hole 22 , and the threeoutlets 21 on theside plate 24 are arranged at intervals in the circumferential direction of theside plate 24 . In this way, the vortex formed by the airflow in therestrictor 2 can be significantly reduced, thereby reducing the flow loss.
