The gate valve utilizes the deformation compensation effect of the overall sealing of the gate plate to achieve good sealing effect, overcoming the phenomena of poor sealing, water leakage, and rust in general gate valves. It can be widely used as a regulating or intercepting device on fluid pipelines such as tap water, sewage, construction, power, petrochemical, pharmaceutical, food, shipbuilding, metallurgical energy systems, etc.
The threaded gate valve is a widely used valve, and its popularity is due to the small friction between the sealing surfaces during the opening and closing process, its durability, small opening height, easy manufacturing, and convenient maintenance. It is not only suitable for medium and low pressure, but also for high pressure. Its closing principle is to rely on the pressure of the valve stem to tightly fit the sealing surface of the valve disc and the sealing surface of the valve seat, preventing the flow of medium.
