Plane steel gate is a kind of hydraulic product widely used in water conservancy and electric power engineering. It plays a role of interception flow in engineering, so as to facilitate the normal operation of subsequent equipment or other work. The steel gate produced by our company has a plane sliding block type steel gate, and the plane wheel type steel has been used. The gate manufactured by our company can be used in conjunction with the sluice groove to achieve the advantages of easy switching, good sealing performance, less than 0.03 knows/seconds of water seepage per meter length, easy installation and use, good water-proof performance and strong anti-corrosion performance. 1. Planar slider type steel gate: The gate is composed of gate blade frame, rubber water seal, locking beam, slider and so on. The gate has no lock beams at the left and right ends except for sealing water. When it needs to be repaired, the gate is supported on the groove. The slider is made of oily nylon, which is corrosion resistant and has friction coefficient of one third of steel.
