軸流式止回閥產(chǎn)品概述
軸流式止回閥具有一般止回閥的功能外,它還設(shè)計(jì)有減震彈簧,具有消聲、減震效果,便于用戶現(xiàn)場(chǎng)檢修,的軸流式結(jié)構(gòu)具有流阻小,流量大,外形尺寸小等特點(diǎn),是國(guó)內(nèi)外油氣集輸管網(wǎng)系統(tǒng),特別是輸油泵出口。適用于油、氣、水漿液管道系統(tǒng),防止介質(zhì)逆流使用。軸流式止回閥結(jié)構(gòu)特點(diǎn)
1、單體機(jī)構(gòu),重量輕,剛性好,便于維護(hù)。2、彈簧的推力使閥瓣在即使無(wú)介質(zhì)壓力時(shí),也能處于關(guān)閉位置。
3、良好的支撐方式使閥門無(wú)論處于什么安裝位置,閥瓣和閥座都能良好對(duì)中,故閥門可以任意安裝。
4、閥門外形的流線型設(shè)計(jì)與體腔流線型設(shè)計(jì)的組合構(gòu)成了軸流式止回閥流線型流道,精確的計(jì)算和設(shè)計(jì)使流道的過(guò)留面積充分保持一致,壓力損失小,流態(tài)穩(wěn)定,無(wú)汽蝕。閥瓣在介質(zhì)流動(dòng)時(shí)產(chǎn)生負(fù)壓及彈簧推力下回座,無(wú)介質(zhì)對(duì)閥瓣背面直接沖擊,因此軸流式止回閥是低噪音閥門
5、閥瓣前后兩端支承和閥瓣軸的特殊表面處理和結(jié)構(gòu)設(shè)計(jì),克服了這類閥門在使用中發(fā)生卡阻的現(xiàn)象。
