先導活塞(sai)式(shi)蒸汽減壓閥技術說明：

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(dao)活(huo)塞式(shi)蒸汽減壓(ya)閥(fa)(fa)由(you)(you)主閥(fa)(fa)和導(dao)閥(fa)(fa)兩部分組(zu)成(cheng)。主閥(fa)(fa)主要由(you)(you)閥(fa)(fa)座、主閥(fa)(fa)盤、活(huo)塞、彈簧(huang)(huang)(huang)等(deng)零件組(zu)成(cheng)。導(dao)閥(fa)(fa)主要由(you)(you)閥(fa)(fa)座、閥(fa)(fa)瓣、膜片、彈簧(huang)(huang)(huang)、調節彈簧(huang)(huang)(huang)等(deng)零件組(zu)成(cheng)。本(ben)產(chan)品在(zai)普(pu)通減壓(ya)閥(fa)(fa)基礎上作了很(hen)大(da)(da)改進，加(jia)(jia)大(da)(da)了活(huo)塞面積，改變了節流結構與密(mi)封(feng)形式(shi)，加(jia)(jia)大(da)(da)了過流面積等(deng)等(deng)，從而在(zai)提高靈敏(min)度、流量、壽命等(deng)方(fang)面大(da)(da)大(da)(da)改善(shan)了性能。主要用(yong)于(yu)蒸汽管路(lu)，適用(yong)于(yu)流量大(da)(da)流量變化(hua)大(da)(da)，進口壓(ya)力(li)變化(hua)大(da)(da)的蒸汽管路(lu)。
