钢制闸门主要材料为不锈钢或碳钢碰涂环氧树脂涂料，橡胶软密封，具有重量轻，操作灵活，防腐蚀，不生锈，安装维修方便，密封可靠等功能，广泛应用于自来水厂、污水厂、排灌、排涝、石油、化工、冶金、环保、电力、塘堰、河流等工程，作为截止、调节流量和控制水位之用。渠道闸门产品特点：重量轻:约为普通闸门的1/3重量。耐腐蚀:耐酸碱及耐大部分腐蚀性化学品及污水、海水等。密封性好:采用橡胶软密封，密封效果好力矩小:由于闸板重量轻，且闸板与道轨板之间摩擦阻力小，故操作力矩小。寿命长:闸板与导轨之间装有防锁死结构使密封面磨损非常小。维修方便:若经多年使用后出现泄漏现象，只需将闸板吊起，调换门框上橡胶密封圈即可，省时省力，维修成本低。手动操作:采用螺杆式启闭操作，操作方便、轻巧、可靠。

The main material of steel gate is stainless steel or carbon steel coated with epoxy resin, rubber soft sealing, light weight, flexible operation, anti-corrosion, rust-free, easy installation and maintenance, sealing reliable and other functions, widely used in water works, sewage plants, drainage and irrigation, drainage, petroleum, chemical, metallurgy, environmental protection, electricity, chemical, chemical, etc. The works such as pond and river are used as cut-off, regulating flow and controlling water level. Channel gate product features: light weight: about 1/3 weight of common gate. Corrosion resistance: acid and alkali resistant and resistant to most corrosive chemicals and sewage, sea water and so on. Good sealing: rubber soft sealing, good sealing torque is small: because the weight of the gate is light, and the friction resistance between the gate and the rail plate is small, so the operating torque is small. Long life: there is an anti lock structure between the gate and the guide rail to make the sealing surface wear very little. Maintenance is convenient: if leakage occurs after many years of use, just lifting the gate and replacing the rubber sealing ring on the door frame can save time and labor, low maintenance cost. Manual operation: screw opening and closing operation is convenient, light and reliable. Electric operation: electric control device, accurate positioning, light operation, easy to achieve automatic control and remote control.
