Description

Technical Field

[0001] The utility model relates to the technical field of gate valves, in particular to an anti-collision 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. According to the difference in the gate plates, gate valves are divided into rigid gate valves and elastic gate valves.

[0003] However, the existing gate valves are generally exposed to the outside. When the gate valve is hit by an external object, the collision object will directly contact the gate valve, which can easily cause damage to the gate valve. At the same time, after the gate valve is installed, it is difficult to improve the humidity of the environment in which the gate valve is located. When the humidity of the environment in which the gate valve is located is too high, it is easy for the surface of the gate valve to rust and damage, which affects the service life of the gate valve to a certain extent. For this reason, we propose an anti-collision gate valve. Utility Model Content
