進(jìn)口蒸汽截止閥工作原理:
進(jìn)口蒸汽波紋管截止閥引進(jìn)國外先進(jìn)技術(shù),采用雙重的密封設(shè)計(jì)若波紋管失效閥桿填料也會(huì)避免泄漏,波紋管焊于閥桿保持穩(wěn)定的運(yùn)行性能,避免由于閥塞振動(dòng)引起閥桿振動(dòng)。完全消除了普通閥門閥桿填料密封老化快易泄露的缺點(diǎn),在高溫情況下,閥桿不與介質(zhì)接觸,保證閥桿的零泄漏。
進(jìn)口蒸汽截止閥產(chǎn)品特點(diǎn):
1、雙重的密封設(shè)計(jì)(波紋管+填料)若波紋管失效,閥桿填料也會(huì)避免。
2、杜絕外泄漏并符合國際密封標(biāo)準(zhǔn)。
3、沒有流體損失降低能源損失提高工廠設(shè)備安全。
4、使用壽命長減少維護(hù)次數(shù)降低經(jīng)營成本。
5、堅(jiān)固耐用的波紋管密封設(shè)計(jì)保證閥桿的零泄漏提供無需維護(hù)的條件。
