YK43XF氣體減壓閥概述：
YK43XF氣體減壓閥主要由主閥和導(dǎo)閥兩大部件組成。適用于工作溫度低于80℃的空氣、液化氣、氧氣等氣體管路上。使用時(shí)旋轉(zhuǎn)調(diào)節(jié)螺桿，頂開導(dǎo)閥盤，介質(zhì)由閥前導(dǎo)管通過導(dǎo)閥腔進(jìn)入主閥上蓋，促使介質(zhì)壓力推動(dòng)活塞，使主閥盤開啟，介質(zhì)流向閥后，同時(shí)由閥后壓力進(jìn)入導(dǎo)閥直接傳遞并作用于膜片下方與膜片上方壓力保持*佳平衡狀態(tài)，達(dá)到減壓目的。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、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。 氣體減壓閥主要用于氣體管路，如空氣減壓閥、氮?dú)鉁p壓閥、氧氣減壓閥、氫氣減壓閥、液化氣減壓閥、天然氣減壓閥等氣體。
