[0002] A gate valve is a closing member, a gate plate. The moving direction of the gate plate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted and throttled. The gate valve is sealed by the contact between the valve seat and the gate plate. Usually, the sealing surface is surfacing welded with metal materials to increase wear resistance. The existing gate valve has a complex structure and is relatively laborious to control the lifting of the gate plate. Based on this, it is necessary to provide a gate valve that can improve the stability of adjusting the lifting of the gate plate and thus improve the convenience of use. In addition, the existing gate valve structure is inconvenient to disassemble, so it is necessary to provide a gate valve with a simple structure and convenient disassembly.
