Cast iron rotating door cover

Cast iron swing gate covers are hydraulic mechanical devices primarily used for flow control and water level regulation in hydraulic engineering, featuring bidirectional rotation capability. The following is a detailed introduction:
Structure and Material
‌Material‌: Made of gray cast iron or ductile iron, offering strong wear resistance and corrosion resistance. ‌
Components‌: Includes gate frame, gate plate, guide rails, sealing strips, and other parts. Some models use bronze or stainless steel materials to enhance sealing performance. ‌
Drive Methods
Optional manual, electric, or pneumatic drives, used in conjunction with hoists, supporting remote control or automated operation. ‌
Specifications and Applicable Scenarios
‌Specifications‌: Common sizes range from DN200 to DN400 (e.g., 200/300/400 series), with maximum dimensions up to DN3000×3000mm. ‌
Applications‌: Widely used in hydraulic engineering such as rivers, reservoirs, urban water supply and drainage, and wastewater treatment, for regulating flow, controlling water levels, or diverting and combining flows. ‌
Features
Sealing Performance‌: Utilizes a wedge-shaped pressure block design, allowing adjustable sealing surfaces to ensure long-term stable water retention. ‌
Durability‌: Features an integrally cast structure, long service life, and low maintenance costs.
