礦井(jing)專用高性能減(jian)壓閥技(ji)術(shu)說明：

本系(xi)列減(jian)(jian)壓(ya)閥(fa)是根據(ju)礦井條件而設計的專用減(jian)(jian)壓(ya)閥(fa)。本閥(fa)由(you)主(zhu)(zhu)閥(fa)、導閥(fa)、壓(ya)力表、針型(xing)閥(fa)等(deng)(deng)幾部分組成(cheng)，主(zhu)(zhu)閥(fa)主(zhu)(zhu)要由(you)閥(fa)座、閥(fa)瓣(ban)、活塞、缸套、彈(dan)簧等(deng)(deng)零(ling)件組成(cheng)。導閥(fa)主(zhu)(zhu)要由(you)閥(fa)座、閥(fa)瓣(ban)、膜片(pian)、彈(dan)簧、調節彈(dan)簧等(deng)(deng)件組成(cheng)。本產品在(zai)普(pu)通(tong)減(jian)(jian)壓(ya)閥(fa)基礎上作(zuo)了(le)很大(da)(da)改(gai)進(jin)，加(jia)大(da)(da)了(le)活塞面積(ji)，改(gai)變(bian)了(le)節流(liu)結構，改(gai)變(bian)可密封形式，加(jia)大(da)(da)了(le)過流(liu)面積(ji)等(deng)(deng)等(deng)(deng)，從而在(zai)提高靈敏度(du)、流(liu)量、壽(shou)命等(deng)(deng)方面大(da)(da)大(da)(da)改(gai)善了(le)性能。
