礦井(jing)專(zhuan)用高性能減壓(ya)閥技術說明：

本(ben)系列(lie)減(jian)壓(ya)閥(fa)(fa)是根據礦(kuang)井條件(jian)而設計(ji)的(de)專用減(jian)壓(ya)閥(fa)(fa)。本(ben)閥(fa)(fa)由主閥(fa)(fa)、導(dao)閥(fa)(fa)、壓(ya)力(li)表(biao)、針型(xing)閥(fa)(fa)等(deng)幾部分組成(cheng)，主閥(fa)(fa)主要(yao)(yao)由閥(fa)(fa)座、閥(fa)(fa)瓣、活塞(sai)(sai)、缸套、彈(dan)簧(huang)等(deng)零件(jian)組成(cheng)。導(dao)閥(fa)(fa)主要(yao)(yao)由閥(fa)(fa)座、閥(fa)(fa)瓣、膜片、彈(dan)簧(huang)、調節彈(dan)簧(huang)等(deng)件(jian)組成(cheng)。本(ben)產品在普通減(jian)壓(ya)閥(fa)(fa)基礎上作了很大(da)(da)改(gai)(gai)進(jin)，加大(da)(da)了活塞(sai)(sai)面(mian)(mian)(mian)積，改(gai)(gai)變了節流(liu)結構(gou)，改(gai)(gai)變可密(mi)封形(xing)式，加大(da)(da)了過流(liu)面(mian)(mian)(mian)積等(deng)等(deng)，從而在提高靈(ling)敏(min)度、流(liu)量、壽命等(deng)方面(mian)(mian)(mian)大(da)(da)大(da)(da)改(gai)(gai)善了性能。
