立体钢闸门是水利、电力工程普遍使用的一种水工产品。在工程中起到阻拦水流的作用，以利于后续设备或其他任务的正常运转。本公司消费的钢闸门有立体滑块式钢闸门，立体定轮式钢曾用名。本公司消费的闸门与闸槽配合运用，能到达开关自若、密封功能好，每米长度的渗水量不超越0.03知/秒该闸门具装置运用方便，止水功能好，防腐功能强等优点。
1、立体滑块式钢闸门：该闸门由门叶框架、橡胶水封、锁定梁、滑块等组成。该闸门除了密封止水外，左右两端没有锁定梁，当须检修时，将闸门支撑在闸槽上，滑块采用含油尼龙，即耐腐蚀且磨擦系数爲钢制的三分之一。

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.
