style="text-indent:25px">止回閥的閥瓣在流體壓力作用下開(kāi)啟，流體從進(jìn)口側(cè)流向出口側(cè)。ＷＣ6高溫止回閥</p><p style="text-indent:25px">旋啟式止回閥安裝方法：一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)通道成流線型，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靜音止回閥同。閥瓣上部和閥蓋下部加工有導(dǎo)向套簡(jiǎn)，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。三、碟式止回閥：閥瓣圍繞閥座內(nèi)的銷(xiāo)軸旋轉(zhuǎn)的止回閥。碟式止回閥結(jié)構(gòu)簡(jiǎn)單，只能安裝在水平管道上，密封性較差。ＷＣ6高溫止回閥</p><p
