YK43F/X氣體減壓閥結(jié)構(gòu)特點(diǎn)和用處

本減壓閥屬于先導(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、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)品主要用于氣體管路，如空氣、氮?dú)狻⒀鯕狻錃狻⒁夯瘹狻⑻烊粴獾葰怏w。
