升降式止回閥

H71單瓣對(duì)夾升降式止回閥

H71單瓣對(duì)夾升降式止回閥該產(chǎn)品采用對(duì)夾式連接,結(jié)構(gòu)緊湊,閥瓣沿著中心定位作 升降運(yùn)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,可顯著減少水錘現(xiàn)象。對(duì)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,H71單瓣對(duì)夾升降式止回閥可適用于水、蒸氣、油品、硝酸、醋酸、強(qiáng)氧化性介質(zhì)等多種介質(zhì)。
