The steel gate of hydropower station is widely used in water supply, water diversion and flood control engineering construction. The pressure of the steel gate of steel dam irrigation factory is 0.1MPa on the gate frame, 0.02MPa on the gate frame, the leakage is not more than 1.25L/min.m, the opening and closing time is 5-10min. It is wall-attached or flange-type installation. 1. It is mainly composed of hoist, cast iron gate (door frame, gate plate, gate rod) wedge tightening device, sealing seat, lifting lug and other components. There are copper inlays on the sealing surface to ensure the sealing and durability. After long-term wear and tear, steel dam irrigation steel gate manufacturers can ensure normal work by wedge-shaped block height. Steel dam irrigation gate manufacturer has reasonable structure, good sealing, installation, regulation, use, easy maintenance, reliable performance and other characteristics.
