They have conducted a lot of research and engineering investment, and adopted a combination of multiple extraction methods to manage mine gas. In the coal mine gas extraction system, orifice flow meters are mostly used for manual detection of extraction flow. Since the extracted gas in the extraction connecting pipe is mostly in a "steam-water" state, especially when the gas is extracted to the ground, due to the temperature difference between the underground and the ground, the gas in the connecting pipe is easy to condense into water when it encounters cold, resulting in poor water flow.

Through the cooperation of the water-absorbing sponge 19, the fixing ring 23 and the filter hole 24, it is convenient to absorb and squeeze out the residual water on the inner wall of the connecting pipe 22; the outer side of the rubber ring 20 is fixedly connected with the first limit block 17, and the outer side of the first limit block 17 is fixedly connected with the second limit block 18, which plays a guiding role for the rubber ring 20; the outer side of the guide rod 16 is provided with a first guide groove 15 adapted to the first limit block 17, and the inner wall side of the first guide groove 15 is provided with a second guide groove 21 adapted to the second limit block 18, which plays a guiding and limiting role for the rubber ring 20; both ends of the traction rope 7 are penetrated by the flow meter body 4, one end of the traction rope 7 is fixedly connected with the first fixing block 6, and the end of the traction rope 7 away from the first fixing block 6 is fixedly connected with the second fixing block 8, which is convenient for resetting the rubber ring 20.

[0024] In this embodiment, a pair of first fixed blocks 6 are dragged, and the first fixed block 6 drives the rubber ring 20 and the water-absorbing sponge 19 to slide along the inner wall of the connecting pipe 22 through the traction rope 7. The rubber ring 20 drives the first limiting block 17 and the second limiting block 18 to slide along the first guide groove 15 and the second guide groove 21. The residual water on the inner wall of the connecting pipe 22 is absorbed by the water-absorbing sponge 19.

The gas flow through the pipeline 1 can be displayed by the display device 5. When the extracted gas in the pipeline 1 is mostly in a "steam-water" state, the gas in the pipeline 1 is easy to condense water when it is cold, and the water flows through the flow meter body 4, causing water to flow poorly. The push block 10 is dragged to drive the movable rod 11 and the movable plug 12 to move away from the internal threaded pipe 14.
