進口先導(dǎo)活塞式氣體減壓閥德國洛克型號齊全

減壓閥的安裝和維護應(yīng)注意以下事項： 

1、減壓閥為了操作和維護方便，該閥一般直立安裝在水平管道上。

2、減壓閥安裝時應(yīng)注意使管路中介質(zhì)的流向與閥休上所示箭頭的方向一致。

減壓閥為了防止閥后壓力超壓，應(yīng)在離閥出口不少于4M處安裝一個安全閥。

進口先導(dǎo)活塞式氣體減壓閥產(chǎn)品簡介：

進口先導(dǎo)活塞式氣體減壓閥屬于先導(dǎo)活塞式減壓閥。由主閥和導(dǎo)閥兩部分組成。主閥主要由閥座、主閥盤、活塞、缸套、彈簧等零件組成。導(dǎo)閥主要由閥座、閥瓣、膜片、彈簧、調(diào)節(jié)彈簧等零件組成。通過調(diào)節(jié)彈簧壓力設(shè)定出口壓力，利用膜片傳感出口壓力變化，通過導(dǎo)閥啟閉驅(qū)動活塞調(diào)節(jié)主閥節(jié)流部位過流面積的大小，實現(xiàn)減壓穩(wěn)壓功能。

Import pilot piston type gas pressure reducing valve belongs to the pilot piston type pressure reducing valve. By the main valve and pilot valve composed of two parts. The main valve mainly by the valve seat, the main valve plate, piston, cylinder liner, springs and other parts. Pilot valve is mainly composed of valve seat, valve disc, diaphragm, spring, adjusting spring and other parts. By adjusting the spring pressure to set the outlet pressure, the diaphragm pressure sensor is used to adjust the flow area of the throttle part of the main valve through the pilot valve opening and closing to drive the piston.
