More specifically, the straight pipe 1 is connected to the gas pipeline through the connecting flange 2. Under normal conditions, the gas is transported through the curved pipe 4 through the diversion effect of the circulation switching component 8, and the gas flow can be detected through the flow meter body 7. When the flow meter body 7 needs to be disassembled and replaced, the circulation switching component 8 is used to control the gas from entering the curved pipe 4, and then the manual adjustment component 6 is used to control the operation of the docking component 5 to release the limit on the curved pipe 4. The curved pipe 4 is pulled backward, and the curved pipe 4 and the flow meter body 7 can be disassembled, thereby facilitating the disassembly and replacement of the flow meter body 7. During the disassembly process, the circulation switching component 8 is used to enable the gas to flow along the inside of the straight pipe 1 without affecting the normal gas transportation.

[0025] The docking assembly 5 includes a fixing sleeve 501, and the fixing sleeve 501 is fixedly installed on the surface of the docking pipe 3, and the end of the bent pipe 4 is movably plugged into the inner wall of the fixing sleeve 501. The surface of the fixing sleeve 501 is slidably connected with a connecting rod 502, and the end of the connecting rod 502 is fixedly connected with a pin 503. The surface of the bent pipe 4 is fixedly connected with a positioning sleeve 504, and the surface of the positioning sleeve 504 is provided with a groove, and the inner wall of the groove is movably plugged into the end of the pin 503.
