Background

The gate valve is a valve plate of opening and closing member, the moving direction of the valve plate is perpendicular to the fluid direction, the gate valve can only be fully opened and fully closed, and can not be adjusted and throttled. The gate valve is sealed by the contact of the valve seat and the valve plate, and a sealing surface is usually subjected to surfacing welding of metal materials to increase the wear resistance, such as 1Cr13, STL6, stainless steel and the like. The valve plate has rigidity valve plate and elasticity valve plate, according to the difference of valve plate, and the gate valve divide into rigidity gate valve and elasticity gate valve.

When the gate valve is closed, the sealing surface can be sealed only by medium pressure, namely, the sealing surface of the valve plate is pressed to the valve seat on the other side by the medium pressure to ensure the sealing of the sealing surface, namely, the self-sealing is realized. Most gate valves are forcedly sealed, namely, when the valves are closed, the valve plate is forced to press the valve seat by external force so as to ensure the sealing performance of a sealing surface.
