The Working Principle Of Cast Iron Gate Valve

Cast iron gates are water retaining elements that directly bear water pressure. The gate frame is the supporting member around the gate plate and is also the chute for the up and down movement of the gate plate. The outer part of the chute is set in the second phase concrete of the gate pier and bottom of the gate, which transfers the water pressure borne by the gate plate evenly to the gate pier and bottom of the gate chamber.

The water-bearing surface around the gate frame and the water-backing surface around the gate frame are smooth and straight after mechanical processing, so that the combined surface, the water stop surface, and the movement chute are combined into one.

When the gate is opened and closed under the action of the opening and closing machine, the tightening ramp and frame chute ensure the longitudinal and transverse running trajectory of the gate. Under the dual action of water pressure and the tight closing tilt iron, the gate plate is ensured to run smoothly. The gate plate and frame chute are tightly fitted so that water is effectively stopped.
