[0002] Pipe valves are devices used to control, adjust, and distribute fluid flow, direction, and parameters in pipeline systems. These devices play a vital role in pipeline systems. By controlling the opening and closing of valves, the flow, pressure, and direction of fluids in pipelines are adjusted to achieve control and normal operation of pipeline systems. The working principle of pipe valves is mainly to control the flow of media through the movement of valve cores or valve plates. When the orifice on the valve core or valve plate is aligned with the pipeline axis, the valve is in an open state, and the medium can pass through the valve channel smoothly. When the valve core or valve plate rotates or moves, and the orifice deviates from the pipeline axis, the valve is in a closed state, and the medium cannot pass through the valve channel. Pipe valves are composed of a valve body and fixed pipes on both sides. During installation, the fixed pipe and the end of the movable pipe need to be welded for use, but the following defects still exist:
