先(xian)導(dao)活塞式蒸(zheng)汽減壓閥技術(shu)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)活塞(sai)式(shi)蒸汽減(jian)壓(ya)閥(fa)由(you)主(zhu)閥(fa)和導(dao)閥(fa)兩部分組成。主(zhu)閥(fa)主(zhu)要由(you)閥(fa)座(zuo)、主(zhu)閥(fa)盤、活塞(sai)、彈簧等零(ling)件(jian)(jian)組成。導(dao)閥(fa)主(zhu)要由(you)閥(fa)座(zuo)、閥(fa)瓣(ban)、膜(mo)片、彈簧、調(diao)節彈簧等零(ling)件(jian)(jian)組成。本產品(pin)在(zai)普通減(jian)壓(ya)閥(fa)基礎上作了(le)很大改進(jin)，加大了(le)活塞(sai)面積(ji)，改變了(le)節流(liu)結構與密封(feng)形式(shi)，加大了(le)過流(liu)面積(ji)等等，從而在(zai)提高(gao)靈敏度、流(liu)量、壽命等方面大大改善了(le)性能。主(zhu)要用(yong)于(yu)蒸汽管(guan)路，適(shi)用(yong)于(yu)流(liu)量大流(liu)量變化大，進(jin)口(kou)壓(ya)力變化大的(de)蒸汽管(guan)路。
