hydraulic operated knife gate valve

The hydraulic knife gate valve structure includes a valve body, a gate and a U-shaped sealing strip, When the valve is closed, the gate moves downward, and the bottom edge of the gate contacts with the sealing strip, thus compressing the sealing strip into the groove to realize the sealing of the valve body and the gate; When the hydraulic knife gate valve is opened, the gate moves up, the bottom edge of the gate is separated from the sealing strip, and the sealing strip springs up and is flat with the groove, which can prevent the medium sediment from accumulating in the groove of the valve body, which is not easy to be blocked and has no residue, and the pipeline cleaning is convenient, so as to effectively improve the sealing effect of the knife gate valve and prevent leakage when the valve is closed. The hydraulic knife gate valve has longer service life and simpler maintenance. The sealing surface of flange is inlaid with O-ring without additional flange gasket. The installation is simple and convenient, the friction coefficient is small, and the opening and closing are flexible.
