[0023] Please refer to Figure 1 and Figure 2 , the pressure relief mechanism 8 includes a gasket 81. The gasket 81 is slidably connected inside the valve body 1. The gasket 81 is annular and made of rubber. By designing the gasket 81, the air inlet 2 can be blocked. A connecting block 82 is fixedly connected to the top of the gasket 81. The connecting block 82 is slidably connected to the valve body 1. A connecting rod 83 is fixedly connected to the top of the connecting block 82. A spring 84 is arranged outside the connecting rod 83. One end of the spring 84 is fixedly connected to the slider 85, and the other end of the spring 84 is fixedly connected to the connecting block 82. By designing the spring 84, the acting force of the spring 84 can act on the slider 85 and the connecting block 82. The slider 85 is slidably sleeved outside the connecting rod 83. A through groove 86 is opened inside the slider 85, and the connecting rod 83 is slidably connected inside the through groove 86. By designing the through groove 86, the connecting rod 83 can slide inside the slider 85. The slider 85 is slidably connected to the valve body 1. A flow channel 88 is opened inside the valve body 1, and the flow channel 88 is communicated with the air outlet 6. By designing the pressure relief mechanism 8, the pipeline can be depressurized after connection.

[0024] Please refer to Figure 1 and Figure 3 and Figure 4 , the exhaust mechanism 9 includes a connecting sleeve 91. The connecting sleeve 91 is slidably connected inside the connecting shell 4.

The outer surface of the valve body 1 is provided with external threads, and the external threads of the valve body 1 are in threaded fit with the internal threads of the wall-mounted pressure reducer for pipeline system connection. When the internal pressure of the pipeline is too high, it will enter the air inlet 2 and push the sealing gasket 81 to separate from the air inlet 2. Subsequently, the gas pushes the connecting block 82 to move. The connecting block 82 drives the connecting rod 83 to slide along the slider 85, and the connecting block 82 compresses the spring 84.

By different displacement amounts of the slider 85, the compression amount of the compression spring 84 can be adjusted, and the pressure setting amount of the safety valve can be flexibly adjusted according to requirements.

[0027] When it is necessary to disassemble the connection sleeve 91, directly rotate the joint 5. The joint 5 rotates relative to the connection disc 96. At the same time, the joint 5 performs a threaded movement. The joint 5 will slide inside the connection shell 4, so that the joint 5 is separated from the connection shell 4, and the connection sleeve 91 can be taken out from the inside of the connection shell 4. It can be freely assembled according to actual needs and is convenient to use.
