Pipelines are usually used to transport media in industrial or civil infrastructure, where the pipeline is regulated due to changes in pressure or temperature. In order to adjust the flow, an adjustment mechanism, especially a ball valve, is used in the pipeline to ensure the best work. conditions and the safety of the environment. Ball valves usually use a sphere with a circular passage as the opening and closing element, and the sphere realizes the opening and closing action with the rotation of the valve body. The opening and closing part of the ball valve is a ball with a through hole, which rotates around the axis perpendicular to the channel, so as to achieve the purpose of opening and closing the channel.
