止回閥安裝在管道轉(zhuǎn)彎彎頭或垂直方向落差較大的地方，也是防止水錘對(duì)管道的影響及破壞，所以應(yīng)該裝在4處，防止回水對(duì)水表的沖擊。一、旋啟式止回閥：旋啟式止回閥的閥瓣呈圓盤(pán)狀，繞閥座通道的轉(zhuǎn)軸作旋轉(zhuǎn)運(yùn)動(dòng)，因閥內(nèi)通道成流線(xiàn)形，流動(dòng)阻力比升降式止回閥小，適用于低流速和流動(dòng)不常變化的大口徑場(chǎng)合，但不宜用于脈動(dòng)流，其密封性能不及升降式。旋啟式止回閥分單瓣式、雙瓣式和多半式三種，這三種形式主要按閥門(mén)口徑來(lái)分，目的是為了防止介質(zhì)停止流動(dòng)或倒流時(shí)，減弱水力沖擊。二、升降式止回閥：閥瓣沿著閥體垂直中心線(xiàn)滑動(dòng)的止回閥，升降式止回閥只能安裝在水平管道上，在高壓小口徑止回閥上閥瓣可采用圓球。升降式止回閥的閥體形狀與截止閥一樣(可與截止閥通用)，因此它的流體阻力系數(shù)較大。其結(jié)構(gòu)與截止閥相似，閥體和閥瓣與截止閥相同，日照對(duì)夾升降式止回閥。閥瓣上部和閥蓋下部加工有導(dǎo)向套簡(jiǎn)，日照對(duì)夾升降式止回閥，日照對(duì)夾升降式止回閥，閥瓣導(dǎo)向簡(jiǎn)可在閥盞導(dǎo)向簡(jiǎn)內(nèi)自由升降，當(dāng)介質(zhì)順流時(shí)，閥瓣靠介質(zhì)推力開(kāi)啟，當(dāng)介質(zhì)停流時(shí)，閥瓣靠自垂降落在閥座上，起阻止介質(zhì)逆流作用。直通式升降止回閥介質(zhì)進(jìn)出口通道方向與閥座通道方向垂直;立式升降式止回閥，其介質(zhì)進(jìn)出口通道方向與閥座通道方向相同，其流動(dòng)阻力較直通式小。寧波鼎力閥門(mén)是一家專(zhuān)門(mén)生產(chǎn)制造銷(xiāo)售止回閥的公司，主要有通風(fēng)止回閥，對(duì)夾雙瓣旋啟式止回閥，液力止回閥。日照對(duì)夾升降式止回閥</p><div
