The invention relates to a hydraulic sealed steel gate. It includes steel gate and gate frame. The steel gate is placed in the gate slot inside the gate frame. A plurality of hydraulic jacks are arranged between the steel gate and the gate frame horizontally. A one-way diverter valve is arranged inside the steel gate. The one-way diverter valve is connected with the hydraulic jack. The one-way diverter valve is connected with the high-pressure electric oil pump. A double p-type rubber is arranged between the steel gate and the gate frame. The piston rod of the hydraulic jack is connected with the The gate frame is in contact with each other. The two sides of the water face of the steel gate are respectively provided with holes. A spring seat is installed in the holes. The spring seat is provided with an extension rod. The extension rod is fixed with a pressing plate located in the spring seat. Between the pressing plate and the spring seat is provided with a spring sheathed on the extension rod. The lower end of the extension rod passes through the bottom of the spring seat and is connected with an adjusting nut. The front end of the extension rod is connected with a roller through a pin shaft. The steel gate The back water surface is provided with L-type rubber which fits and seals with the gate frame. The invention has the advantages of simple structure, good waterstop effect, bidirectional waterstop and long service life.

一种液压密封式钢闸门
本专利技术涉及一种钢闸门，尤其涉及一种液压密封式钢闸门。
技术介绍
目前，国内市政、环保、电力、排水、污水处理、泵站、渠道排灌等工程的进、出水口，通常采用安装铸铁闸门来达到止水的目的，现有的钢闸门的结构包括闸门框、闸门和止水橡胶，由于长时间的开启和关闭，会导致止水橡胶磨损严重，使得钢闸门与闸门框之间的间隙越来越大，导致止水效果差，影响了钢闸门的正常工作性能，容易造成安全事故。
技术实现思路
针对上述缺陷，本专利技术的目的在于提供一种结构简单，止水效果好，可实现双向止水，减少止水橡胶磨损的一种液压密封式钢闸门。为此本专利技术所采用的技术方案是：包括钢闸门和闸门框，所述钢闸门放置在闸门框内侧的闸门槽内，钢闸门与闸门框之间横向设有多个液压千斤顶，所述钢闸门内部设有单向分流阀，单向分流阀通过若干高压软管与液压千斤顶连接，单向分流阀通过管路连接有高压电动油泵，钢闸门迎水面两侧与闸门框之间分别设有双P型橡胶，液压千斤顶位于双P型橡胶背面，液压千斤顶的活塞杆贯穿钢闸门背水面与闸门框...
