H71W對夾升降式止回閥該產(chǎn)品采用對夾式連接,結構緊湊,閥瓣沿著(zhù)中心定位作 升降運動(dòng),由于閥瓣的關(guān)閉行程短,并有彈簧加載,關(guān)閉速度快,可顯著(zhù)減少水錘現象。對夾升降式止回閥具有體積小、重量輕、動(dòng)作靈敏、密封可靠、安裝方便等特點(diǎn),特別適合于安裝空間受限制的場(chǎng)合采用,H71W單瓣對夾升降式止回閥可適用于水、蒸氣、油品、硝酸、醋酸、強氧化性介質(zhì)等多種介質(zhì)。
設計制造:JB/T8937
結構長(cháng)度:JB/T8937
配管法蘭:JB/T74
試驗與檢驗:JB/T9092-1999
二、H71(H/W/X/F)不銹鋼對夾式止回閥特點(diǎn):1、具有結構短、體積小、質(zhì)量輕;
2、閥瓣關(guān)閉快速,水錘壓力??;
3、流道通暢,流體阻力??;動(dòng)作靈敏,密封性能好
