Hydraulic Cast Iron Sluice Gate is a heavy-duty vertical lifting sluice gate integrated with hydraulic driving system,mainly made of high-strength gray cast iron and ductile iron.It is specially applied for large-flow,high-water-head water flow interception,opening,closing and flow regulation in water conservancy,municipal sewage and industrial pipeline projects.

Structure&Materials

The overall body consists of gate frame,gate leaf,sealing parts,lifting mechanism and hydraulic power unit.

The gate body is cast from premium HT250 gray cast iron or ductile iron with dense casting structure,strong compressive resistance and excellent deformation resistance.Inlaid bronze sealing strips are adopted for metal hard seal,and optional EPDM soft rubber seal is available for ultra-low leakage requirement.

All transmission shafts and connecting components are made of stainless steel with high corrosion resistance.The whole surface is coated with heavy-duty anti-corrosion epoxy resin coating,which can resist long-term erosion of sewage,silt and corrosive water quality.

Built-in self-tightening wedge structure ensures tight closing on both sides of water pressure.

Features

Hydraulic Automatic Operation

Driven by hydraulic cylinder and hydraulic station,it realizes stable lifting,large driving force,smooth opening and closing,and no jamming under heavy water pressure.Supports automatic control,remote operation,interlock linkage and intelligent system integration.

High Sealing Performance

Bidirectional pressure bearing and bidirectional sealing design,minimal water leakage,stable sealing effect under high water head.

Superior Durability

Solid cast iron structure has outstanding wear resistance,pressure resistance and corrosion resistance,with long service life over 30 years.

Large Adaptable Flow Range

Suitable for large-section channels,large water volume working conditions which manual gate is hard to operate.

Low Maintenance

Compact overall structure,few vulnerable parts,stable hydraulic system,simple daily maintenance and low operation cost.
