Description

Technical Field

[0001] This utility model relates to the field of safety valves, and in particular to a leak-proof safety valve assembly. Background Technology

[0002] Leak-proof safety valves are core safety devices in gas transmission systems. Through active monitoring, intelligent control, and rapid response, they prevent accidents such as explosions, poisoning, and fires caused by gas leaks.

[0003] Leak-proof safety valves utilize detection sensors installed on the side of the pipeline to sense and detect abnormal conditions. Since the valve body is usually made of steel, it has a certain degree of pressure and impact resistance. However, the detection sensor is directly installed on one side of the leak-proof safety valve through the pipeline. This increases the probability of the detection sensor being impacted or squeezed, especially outdoors. Consequently, when the detection sensor is impacted or squeezed, the pipeline connecting the detection sensor and the leak-proof safety valve may bend, deform, or even be damaged, thus reducing the lifespan of the detection sensor and presenting a certain defect.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1: This utility model provides the following... Figures 1-2 The leak-proof safety valve assembly shown includes a safety valve body 1, a detection sensor 2, a protective housing 3, a positioning plate 4, and a fixing component. The detection sensor 2 is fixedly installed on one side of the safety valve body 1 via a connecting pipe. The detection sensor 2 detects abnormal conditions of the safety valve body 1 through the connecting pipe, which is prior art and will not be described in detail here. The protective housing 3 is symmetrically arranged on one side of the safety valve body 1. The protective housing 3 is used to shield and protect the detection sensor 2. That is, two protective housings 3 are symmetrically fitted onto the outside of the detection sensor 2, and a groove corresponding to the connecting pipe is opened on one side of the bottom of the protective housing 3. Thus, the two protective housings 3 will not obstruct the pipe through which the detection sensor 2 is connected during installation. One end of the positioning plate 4 is fixedly connected to the safety valve body 1. The positioning plate 4 is snapped into the inside of the protective housing 3. That is, two positioning plates 4 are snapped into the top and bottom of the inner cavity of the protective housing 3, which can limit the movement of the protective housing 3. The fixing component is set on the protective housing 3. The fixing component is used to lock and limit the positioning plate 4 and the protective housing 3, thereby ensuring the stability of the installation of the protective housing 3.

[0016] Furthermore, the fixing component includes a fixing bolt 51, which is installed on the side of the protective housing 3. A threaded hole is provided on one side of the positioning plate 4. The outer wall of the fixing bolt 51 is threadedly connected to the inner cavity of the threaded hole. The fixing bolt 51 can ensure the stability of the installation of the protective housing 3. The protective housing 3 can be disassembled by removing the fixing bolt 51. The fixing bolt 51 is used to fix the protective housing 3, which can ensure the stability of the installation of the protective housing 3.

[0017] Example 2: Unlike Example 1, as follows... Figure 3As shown, the fixing component includes a fixing block 52, a positioning hole, a locking block 53, and a locking hole. The fixing block 52 is fixedly connected to the inside of the protective housing 3. The positioning hole is opened on one side of the positioning plate 4. The outer wall of the fixing block 52 is slidably engaged with the inner cavity of the positioning hole. The locking block 53 is located on the side of the positioning plate 4 away from the protective housing 3. The locking block 53 is opened on the side of the fixing block 52. The outer side of the locking block 53 is slidably engaged with the inner cavity of the locking hole. The locking block 53 engages and locks the fixing block 52, which can ensure the stability of the connection between the protective housing 3 and the positioning plate 4. The locking and limiting of the protective housing 3 by using the locking block 53 and the fixing block 52 can improve the convenience of disassembling the protective housing 3.

[0018] Furthermore, the fixing assembly also includes a connector 54 and a button 55. The connector 54 is slidably disposed on the side of the inner cavity of the protective housing 3. One side of the locking block 53 is fixedly connected to the connector 54. The button 55 is fixedly connected to the middle of one side of the connector 54. One side of the protective housing 3 has a hole corresponding to the button 55, that is, the button 55 is slidably sleeved inside the hole. By squeezing the button 55, the connector 54 can cause the locking block 53 to separate from the fixing block 52, thereby releasing the locking state of the protective housing 3, so that the protective housing 3 can be directly slid off.

[0019] Furthermore, the fixing assembly also includes a fixing plate 56, a guide rod 58, and a limiting spring 57. The fixing plate 56 is fixedly connected to the inside of the protective housing 3. The ends of the guide rod 58 are fixedly connected to the fixing plate 56 and the protective housing 3 respectively. The outer wall of the guide rod 58 is slidably inserted into the connector 54. The guide rod 58 can ensure the stability of the connector 54 sliding inside the protective housing 3. The limiting spring 57 is slidably sleeved on the outside of the guide rod 58. The limiting spring 57 is located between the fixing plate 56 and the connector 54. The limiting spring 57 can give the connector 54 an elastic compressive force towards the fixing block 52, so that the connector 54 drives the locking block 53 to be in a stable snap-fit ​​state with the fixing block 52, thereby ensuring the stability of the installation of the protective housing 3.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
