Description

Technical Field

[0001] The utility model relates to the technical field of gate valves, in particular to a fast-closing gate valve. Background Art

[0002] The gate valve is a gate plate that opens and closes. 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 is welded with metal materials to increase wear resistance. There are rigid gate plates and elastic gate plates. Depending on the gate plates, gate valves are divided into rigid gate valves and elastic gate valves. Traditional gate valves adjust the flow rate through threads, but cannot achieve the effect of quickly closing the valve. For this reason, we propose a fast-closing gate valve. Utility Model Content
