進口先導活塞式氣體減壓閥德國洛克各種參數(shù)以及說明

一、進口先導活塞式氣體減壓閥描述：

德國LOCKE洛克進口先導活塞式氣體減壓閥由主閥和導閥兩部分組成。主閥主要由閥座、主閥盤、活塞、彈簧等零件組成。導閥主要由閥座、閥瓣、膜片、彈簧、調(diào)節(jié)彈簧等零件組成。通過調(diào)節(jié)調(diào)節(jié)彈簧壓力設定出口壓力、利用膜片傳感出口壓力變化，通過導閥啟閉驅(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。

本減壓閥主要用于氣體管路，如空氣、氮氣、氧氣、氫氣、液化氣、天然氣等氣體。

The pilot piston type gas pressure reducing valve imported from Locke lock, Germany is composed of main valve and pilot valve. The main valve is mainly composed of valve seat, main valve disc, piston, spring and other parts. The pilot valve is mainly composed of valve seat, disc, diaphragm, spring, regulating spring and other parts. Through adjusting and adjusting the spring pressure to set the outlet pressure, using the diaphragm to sense the outlet pressure change, and through the pilot valve to open and close the driving piston to adjust the size of the flow area of the throttle part of the main valve, the pressure reducing and stabilizing function is realized.

The pressure reducing valve is mainly used for gas pipeline, such as air, nitrogen, oxygen, hydrogen, liquefied gas, natural gas and other gases.
