The copper-inlaid cast iron square gate is a hydraulic engineering device that combines a cast iron main body with copper sealing elements, primarily used for flow interception, water level regulation, and medium control. It features high strength and corrosion resistance.
Structural Composition
It consists of a gate frame, gate leaf, guide rails, sealing strips, transmission screw rod, and wedge adjustment mechanism. The gate frame and leaf are made of gray cast iron or ductile iron, with guide rails fixed by stainless steel bolts. The sealing surface is inlaid with copper alloy or rubber strips, achieving planar contact sealing through precision machining.
Core Functions
?Bidirectional Pressure Resistance?: Forward pressure resistance of 10 meters water head, reverse pressure resistance of 10 meters water head;
?Sealing Performance?: Sealing gap ≤0.1mm, forward leakage ≤0.7L/m·min, reverse leakage ≤1.25L/m·min;
?Corrosion Resistance?: Suitable for environments from -20°C to 120°C, applicable to media such as sewage and seawater;
?Installation Method?: Supports embedded steel plate or bolt fixation, compatible with manual, electric, or hydraulic hoists.
Application Scenarios
Widely used in municipal water supply and drainage, flood control and drought relief, hydraulic hubs, industrial pipelines, and wastewater treatment, particularly suitable for concealed installation scenarios (such as scenic areas and road infrastructure).
