礦井專用高性能減壓閥技術說(shuo)明：

本系列減(jian)壓(ya)(ya)閥(fa)(fa)(fa)(fa)是根據礦井條件(jian)(jian)而設計的(de)專用減(jian)壓(ya)(ya)閥(fa)(fa)(fa)(fa)。本閥(fa)(fa)(fa)(fa)由主閥(fa)(fa)(fa)(fa)、導(dao)(dao)閥(fa)(fa)(fa)(fa)、壓(ya)(ya)力表(biao)、針型閥(fa)(fa)(fa)(fa)等(deng)幾部分(fen)組(zu)成(cheng)，主閥(fa)(fa)(fa)(fa)主要由閥(fa)(fa)(fa)(fa)座、閥(fa)(fa)(fa)(fa)瓣、活塞(sai)、缸套、彈簧等(deng)零(ling)件(jian)(jian)組(zu)成(cheng)。導(dao)(dao)閥(fa)(fa)(fa)(fa)主要由閥(fa)(fa)(fa)(fa)座、閥(fa)(fa)(fa)(fa)瓣、膜片、彈簧、調節彈簧等(deng)件(jian)(jian)組(zu)成(cheng)。本產(chan)品在(zai)普通減(jian)壓(ya)(ya)閥(fa)(fa)(fa)(fa)基礎上作(zuo)了(le)很大(da)(da)改進，加大(da)(da)了(le)活塞(sai)面(mian)(mian)積，改變(bian)(bian)了(le)節流(liu)結構，改變(bian)(bian)可(ke)密封形式，加大(da)(da)了(le)過流(liu)面(mian)(mian)積等(deng)等(deng)，從而在(zai)提高(gao)靈(ling)敏度(du)、流(liu)量、壽命(ming)等(deng)方面(mian)(mian)大(da)(da)大(da)(da)改善了(le)性能。
