At present, the valve body on the market has a concave spherical surface on the side of the valve body, and the combination of the sealing ring and the side surface of the valve body is a convex spherical surface, and the sealing ring is placed inside the valve body to be lined with the spherical surface. However, in the sewage treatment, food and beverage processing, and pipeline transportation systems of chemical enterprises, such gate valves need to transport fluid media of different natures, which contain various substances that are easy to precipitate and particles that are easy to wear on the gates, so they are used. When the valve is closed, the ram is easily blocked by accumulated particulate matter and the ram is always in a worn state. Most of the gate valves in the prior art are manual gate valves, which require manual manual rotation of the hand wheel, which is time consuming and laborious, and reduces production efficiency.
