Pressure-resistant pipeline for water supply and drainage

The pressure-resistant pipeline for water supply and drainage comprises a first pipe body, a second pipe body and a filtering mechanism, a connecting piece is installed on the left side of the outer wall of the first pipe body, a connecting piece is installed on the right side of the outer wall of the second pipe body, and the left end of the first pipe body and the right end of the second pipe body are connected through the connecting piece; the filtering mechanism comprises a filtering plate; and the filtering plate is fixedly sleeved in the inner cavity of the sleeve plate. By rotating two groups of rotating blocks, the rotating blocks rotate to drive a limiting screw rod to rotate, and the limiting screw rod vertically moves downwards along a threaded hole under the screw-thread fit of the threaded hole, so that the limiting screw rod drives an arc-shaped clamping plate to vertically move downwards through a fixed block, and the arc-shaped clamping plate is matched with a groove plate to clamp a first pip
