Problems solved by technology
[0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, and backflow prevention; when the valve used in the pressure pipeline is switched on and off, it generally needs to be realized by manual operation. However, when the valve is opened and closed, it needs to overcome The pipeline pressure and liquid surface pressure in the pipeline on both sides of the valve require a large torque. At the same time, when the valve is in the open or closed state for a long time, the fluid in the pipeline adheres to the valve plate, making it difficult for the valve stem to rotate when it rotates. The critical friction force when the rod just rotates and the residual stress left when the valve is fully opened or fully closed all increase the difficulty of opening and closing the valve, which may cause the valve to not be closed or opened in time; in order to solve the above problems, the present invention consists of This produces
