[0002] A gate valve is a gate plate of an opening and closing component. The movement direction of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed by the contact between the valve seat and the gate plate. Usually, the sealing surface will be welded with metal materials to increase wear resistance, such as cladding 1Cr13, STL6, stainless steel, etc. The gate plate has a rigid gate plate and an elastic gate plate. Depending on the gate plate, the gate valve is divided into a rigid gate valve and an elastic gate valve. The gate valve has the advantages of simple structure, small flow resistance, and good sealing. It is widely used in industrial fields, especially in pipeline systems.
