The clamping member 10 is provided with semi-arc openings 100 in three directions, and two clamping members 10 are symmetrically arranged to form a clamping assembly 1 in the form of a "tee". A plurality of first through holes 110 are arranged on the clamping member 10 around the semi-arc opening 100. Two sealing gaskets 2 are respectively arranged on the sides of the clamping member 10 close to each other, and the sealing gasket 2 is arranged around the edge of the clamping member 10. A second through hole 200 is arranged on the sealing gasket 2 corresponding to the position of the first through hole 110. The bolt 3 penetrates the first through hole 110 and the second through hole 200 to fix the two clamping members 10 in position, and the two ends of the natural gas pipeline are connected to two ports of the connecting tee 4, one end of the connecting pipe 5 is connected to one port of the connecting tee 4, and the diaphragm pressure gauge 6 is connected to the connecting pipe 5. When the natural gas pipeline leakage position is detected, the natural gas is turned off, the pipeline position is cut off, the two ends of the natural gas pipeline are installed into the connecting tee 4, and the connecting pipe 5 is connected to the other port of the connecting tee 4. One end of the connecting pipe 5 is connected to the diaphragm pressure gauge 6. Two clamps 10 are wrapped outside the connecting tee 4.

The gasket 7 is used to better connect the bolt 3 to the clamping part 10. When the two clamping parts 10 are close to each other, the bolt 3 and the gasket 7 make the two clamping parts 10 better sealed and connected at the leakage point of the natural gas pipeline.

[0032] In this embodiment, the clamping member 10 is preferably a metal structure, and a color coating having a warning function is applied on the surface of the metal clamping member 10 to prompt the operator to observe the position.
