進(jìn)口高壓閘閥工作原理：

1、采用壓力自緊式密封結(jié)構(gòu)，彈性閘板，兩端支管為焊接連。

2、閥座密封面采用鈷基硬質(zhì)合金等離子噴焊而成，耐磨、抗擦傷性能好。

閥瓣密封面經(jīng)硬化氮化處理。

3、閥桿表面經(jīng)抗蝕性氮化處理，有良好的抗腐蝕和抗擦傷性。

4、閥門的開啟和關(guān)閉由電動裝置來控制，電動裝置分別配有專用電機(jī)，減速器、轉(zhuǎn)矩控制機(jī)構(gòu)、現(xiàn)場操作機(jī)構(gòu)、手、電動切換機(jī)構(gòu)，除就地操作外還可進(jìn)行遠(yuǎn)距離操作。

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.
                                                                               

進(jìn)口高壓閘閥產(chǎn)品簡介：

德國洛克《DE LOCKE》進(jìn)口高壓閘閥也稱電站專用閥門，主要適用于火力電站各種系統(tǒng)的管路上，切斷或接通管路介質(zhì)。電站閥門與其他閥門產(chǎn)品相比的特點(diǎn)是高溫高壓，獨(dú)特的自密封設(shè)計(jì)，壓力越高，密封越可靠。由于性能技術(shù)特性、工況的特殊使產(chǎn)品也形成了其他產(chǎn)品所替代不了的特點(diǎn)。本類閥門在管道中一般應(yīng)當(dāng)水平安裝。   

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.
