Several sets of bolt and nut assemblies 5 are provided. The top sealing device 3 is installed on top of the bottom sealing device 3. The bottom sealing device 2 and the top sealing device 3 are fixed together by several sets of bolt and nut assemblies 5. The hydrogen detection sensor 4 is installed on top of the top sealing device 3, with its bottom detection end located inside the top sealing device 3.

The top sealing device 3 includes a top sealing box 10 and a top connecting gasket 11. The top sealing box 10 has a rectangular structure, with its interior and bottom being interconnected. The top connecting gasket 11 has a rectangular structure, and a set of top connecting gaskets 11 are provided. The top connecting gasket 11 and the top sealing box 10 are smoothly transitioned and integrally formed. The set of top connecting gaskets 11 are located at the bottom left and bottom right of the top sealing box 10.

Pipe embedding grooves 8 are provided at both the bottom front and bottom rear of the top sealing box 10. During use, the operator...

[0024] The bottom sealing box 6 has two sets of guide block embedding grooves 17 arranged symmetrically on the top. The guide block embedding grooves 17 are rectangular in shape and are designed to facilitate the insertion of guide blocks 15.

[0025] The top sealing box 10 has a set of symmetrically distributed guide blocks 15 at its bottom. The guide blocks 15 are rectangular in shape and have guide gaskets 16 on their surfaces. The guide gaskets 16 are made of rubber. The top sealing box 10 has an instrument detection end mounting port 12 at its top center.

After fixing, the bottom sealing box 6 and the top sealing box 10 can be fixed at the joint of a set of pipes. In this way, the pipe joint is located in the cavity formed by the bottom sealing box 6 and the top sealing box 10.
