進(jìn)口可調(diào)式高壓減壓閥(德國(guó)OLES奧萊斯閥門)
【進(jìn)口可調(diào)式高壓減壓閥】結(jié)構(gòu)特點(diǎn):
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)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(dòng)活塞調(diào)節(jié)主閥節(jié)流部位過流面積的大小,實(shí)現(xiàn)減壓穩(wěn)壓功能。本產(chǎn)品主要用于蒸汽管路,起減壓穩(wěn)壓作用。
The pressure relief valve belongs to the pilot piston type pressure relief valve. It consists of main valve and pilot valve. The main valve is mainly composed of seat, main disc, piston, cylinder liner, spring and other parts. The guide valve is mainly composed of seat, disc, diaphragm, spring, adjusting spring and other parts. The outlet pressure is set by adjusting the spring pressure, the diaphragm is used to sense the outlet pressure change, and the pilot valve is used to open and close the driving piston to adjust the size of the throttle area of the main valve so as to realize the function of reducing pressure and stabilizing pressure. This product is mainly used in steam pipeline, which can reduce pressure and stabilize pressure.
