4、阀门的开启和关闭由电动装置来控制，电动装置分别配有专用电机，减速器、转矩控制机构、现场操作机构、手、电动切换机构，除就地操作外还可进行远距离操作。

Working principle of imported high pressure gate valve:
1. It adopts pressure self tightening sealing structure, elastic ram and welded branch pipes at both ends.
2. The sealing surface of the valve seat is made of cobalt base cemented carbide by plasma spray welding, with good wear resistance and abrasion resistance.
The sealing surface of the disc is hardened and nitrided.
3. The surface of the valve stem is treated by corrosion resistance nitriding, which has good corrosion resistance and scratch resistance.
4. The opening and closing of the valve is controlled by the electric device. The electric device is equipped with special motor, reducer, torque control mechanism, on-site operation mechanism, manual and electric switching mechanism. In addition to local operation, it can also carry out remote operation.
                                                                               

进口高压闸阀产品简介：

德国洛克《DE LOCKE》进口高压闸阀也称电站专用阀门，主要适用于火力电站各种系统的管路上，切断或接通管路介质。电站阀门与其他阀门产品相比的特点是高温高压，独特的自密封设计，压力越高，密封越可靠。由于性能技术特性、工况的特殊使产品也形成了其他产品所替代不了的特点。本类阀门在管道中一般应当水平安装。   

Introduction of imported high pressure gate valve products:
German Locke "de Locke" imported high pressure gate valve, also known as power station special valve, is mainly used for cutting off or connecting pipeline medium in various systems of thermal power station. Compared with other valve products, power station valve features high temperature and high pressure, unique self sealing design. The higher the pressure, the more reliable the seal. Due to the special performance, technical characteristics and working conditions, the product has formed the characteristics that can not be replaced by other products. This kind of valve should be installed horizontally in the pipeline.
