H41H/WH41H/W升降式止回閥
【簡單介紹】
【詳細(xì)說明】
簡述:升降式止回閥是指依靠介質(zhì)本身流動而自動開、閉閥瓣,用來防止介質(zhì)倒流的閥門,又稱逆止閥、單向閥、逆流閥、和背壓閥。止回閥屬于一種自動閥門,其主要作用是防止介質(zhì)倒流、防止泵及驅(qū)動電動機(jī)反轉(zhuǎn),以及容器介質(zhì)的泄放。
產(chǎn)品特點(diǎn):
H41H/W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 , 襯套采用耐磨性能好,摩擦系數(shù)小的特殊材料制作,動作靈活可靠 . 密封性能優(yōu)良。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。
