產(chǎn)品名稱：升降式止回閥
H41Y不銹鋼升降式止回閥是指依靠介質(zhì)本身流動(dòng)而自動(dòng)開(kāi)、閉閥瓣，用來(lái)防止介質(zhì)倒流的閥門(mén)，又稱逆止閥、單向閥、逆流閥、和背壓閥。止回閥屬于一種自動(dòng)閥門(mén)，其主要作用是防止介質(zhì)倒流、防止泵及驅(qū)動(dòng)電動(dòng)機(jī)反轉(zhuǎn)，以及容器介質(zhì)的泄放。H41Y不銹鋼升降式止回閥嚴(yán)格按 GB12235 標(biāo)準(zhǔn)設(shè)計(jì)制造，閥瓣沿著中心定位作升降運(yùn)動(dòng) , 襯套采用耐磨性能好，摩擦系數(shù)小的特殊材料制作，動(dòng)作靈活可靠 . 密封性能優(yōu)良。H41Y不銹鋼升降式止回閥產(chǎn)品廣泛應(yīng)用于石油、化工、制藥、電力行業(yè)等各種工況的管路上。
