先導活塞式(shi)蒸汽減壓(ya)閥技術說明(ming)：

Y43H-25 型先導活塞式蒸汽減壓閥：法蘭連接形式、活塞式結構形式，閥座密封面材料為 Cr13 系不銹鋼，公稱壓力 PN25，閥體材料為 WCB 的蒸汽減壓閥。
Y43H-25 型先導活(huo)(huo)(huo)塞式蒸汽(qi)減壓閥(fa)(fa)由主(zhu)閥(fa)(fa)和導閥(fa)(fa)兩部分(fen)組(zu)成。主(zhu)閥(fa)(fa)主(zhu)要(yao)由閥(fa)(fa)座、主(zhu)閥(fa)(fa)盤(pan)、活(huo)(huo)(huo)塞、彈簧(huang)等(deng)(deng)(deng)零(ling)件組(zu)成。導閥(fa)(fa)主(zhu)要(yao)由閥(fa)(fa)座、閥(fa)(fa)瓣、膜片(pian)、彈簧(huang)、調節(jie)彈簧(huang)等(deng)(deng)(deng)零(ling)件組(zu)成。本(ben)產品在(zai)普通減壓閥(fa)(fa)基(ji)礎上作了(le)(le)很(hen)大改(gai)進，加大了(le)(le)活(huo)(huo)(huo)塞面積(ji)(ji)，改(gai)變了(le)(le)節(jie)流(liu)結(jie)構與密封形式，加大了(le)(le)過流(liu)面積(ji)(ji)等(deng)(deng)(deng)等(deng)(deng)(deng)，從而在(zai)提(ti)高靈敏度、流(liu)量(liang)、壽(shou)命等(deng)(deng)(deng)方面大大改(gai)善了(le)(le)性(xing)能。主(zhu)要(yao)用于(yu)蒸汽(qi)管路(lu)，適(shi)用于(yu)流(liu)量(liang)大流(liu)量(liang)變化大，進口壓力變化大的蒸汽(qi)管路(lu)。
