The function of the pressure sensor 70 is that when gas leaks, the internal pressure of the gas leakage collection chamber 50 will change accordingly, and the pressure sensor 70 is used for detection.

[0037] In the present utility model, the other end of the first inner pipe fitting 310 and the valve body 20 are of an integral structure.

[0038] In the present utility model, a sealing ring is sleeved on the outer wall of the outer pipe fitting. The sealing ring is arranged at the connection between the second outer tube 420 and the first outer pipe fitting 320. The inner wall of the sealing ring is threadedly connected to the outer wall of the second outer tube 420 and the outer wall of the first outer pipe fitting 320.
