Concealed stem copper-inlaid cast iron square gate

The concealed stem copper-inlaid cast iron square gate is a type of gate used in hydraulic engineering for intercepting flow and regulating water levels. The main body is made of cast iron, with sealing surfaces inlaid with copper alloy or rubber, featuring corrosion resistance and high pressure-bearing capacity.
Structural Features
Material: The gate frame and gate leaf are made of gray cast iron or ductile iron, with sealing surfaces inlaid with copper alloy or rubber, achieving planar contact sealing after precision machining.
Design: The external arc-shaped structure ensures uniform stress distribution, with guide rail lengths ranging from 1/2 to 1/3 of the gate height to enhance stability.
Sealing: The sealing gap is adjusted via a wedge device, with forward leakage ≤0.7 L/m·min and reverse leakage ≤1.25 L/m·min.
