先導(dao)活塞(sai)式蒸汽減壓閥(fa)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(xing)先導活塞(sai)式蒸汽減壓(ya)閥(fa)(fa)由(you)主(zhu)(zhu)閥(fa)(fa)和導閥(fa)(fa)兩(liang)部分(fen)組(zu)(zu)成。主(zhu)(zhu)閥(fa)(fa)主(zhu)(zhu)要(yao)(yao)由(you)閥(fa)(fa)座、主(zhu)(zhu)閥(fa)(fa)盤、活塞(sai)、彈(dan)(dan)簧等零件組(zu)(zu)成。導閥(fa)(fa)主(zhu)(zhu)要(yao)(yao)由(you)閥(fa)(fa)座、閥(fa)(fa)瓣、膜片、彈(dan)(dan)簧、調節(jie)彈(dan)(dan)簧等零件組(zu)(zu)成。本產品在普通(tong)減壓(ya)閥(fa)(fa)基(ji)礎上作了很大改(gai)進，加(jia)大了活塞(sai)面積(ji)，改(gai)變(bian)了節(jie)流(liu)(liu)結(jie)構與密封形式，加(jia)大了過(guo)流(liu)(liu)面積(ji)等等，從而(er)在提(ti)高靈(ling)敏(min)度、流(liu)(liu)量、壽命(ming)等方面大大改(gai)善(shan)了性能。主(zhu)(zhu)要(yao)(yao)用(yong)于蒸汽管(guan)路(lu)，適用(yong)于流(liu)(liu)量大流(liu)(liu)量變(bian)化(hua)大，進口壓(ya)力變(bian)化(hua)大的蒸汽管(guan)路(lu)。
