DMZ673XPneumatic concealed rod knife gate valve

DMZ673XThe valve body of the pneumatic concealed rod knife shaped gate valve is a flat plate structure connected to the pipeline clamp. The gate plate adopts a single gate plate, with one side sealed with the valve seat of the valve body, and the back side in wedge-shaped contact with the other side of the valve body. The sealing surface is opposite to the flow direction of the medium. The wedge-shaped contact structure is equipped with wedge-shaped compression blocks on the back of the sealing surface, and an adjusting top wire is provided at the corresponding compression block on the other side of the valve body.

This utility model has the advantages of a short valve body structure length, light weight, a valve seat sealing surface that can be protected from medium erosion, uniform pressure on the sealing surface, tight fit, the ability to scrape away dust particles, tar, and other debris on the valve seat sealing surface during the closing process, and convenient drainage. Suitable for use in gas pipelines containing dust or tar.
