止回閥是指啟閉件為圓形閥瓣并靠自身重量及介質(zhì)壓力產(chǎn)生動(dòng)作來阻斷介質(zhì)倒流的一種閥門。屬自動(dòng)閥類,又稱逆止閥、單向閥、回流閥或隔離閥。閥瓣運(yùn)動(dòng)方式分為升降式和旋啟式。升降式止回閥與截止閥結(jié)構(gòu)類似,僅缺少帶動(dòng)閥瓣的閥桿。介質(zhì)從進(jìn)口端(旋啟式止回閥有一個(gè)斜置并能繞軸旋轉(zhuǎn)的閥瓣,工作原理與升降式止回閥相似。止回閥常用作抽水裝置的底閥,可以阻止水的回流。止回閥與截止閥組合使用,可起到安全隔離的作用。缺點(diǎn)是阻力大,關(guān)閉時(shí)密封性差
工作原理
其中止回閥就屬于這種類型的閥門,它包括旋啟式止回閥和升降式止回閥。旋啟式止回閥有一介鉸鏈機(jī)構(gòu),還有一個(gè)像門一樣的閥瓣自由地靠在傾斜的閥座表面上。為了確保閥瓣每次都能到達(dá)閥座面的合適位置,閥瓣設(shè)計(jì)在鉸鏈機(jī)構(gòu),以便閥瓣具有足夠有旋啟空間,并使閥瓣真正的、全面的與閥座接觸。閥瓣可以全部用金屬制成,也可以在金屬上鑲嵌皮革、橡膠、或者采用合成覆蓋面,這取決于使用性能的要求。旋啟式止回閥在打開的狀況下,流體壓力幾乎不受阻礙,因此通過閥門的壓力降相對(duì)較小。升降式止回閥的閥瓣坐落位于閥體上閥座密封面上。此閥門除了閥瓣可以自由地升降之外,其余部分如同截止閥一樣,流體壓力使閥瓣從閥座密封面上抬起,介質(zhì)回流導(dǎo)致閥瓣回落到閥座上,并切斷流動(dòng)。根據(jù)使用條件,閥瓣可以是全金屬結(jié)構(gòu),也可以是在閥瓣架上鑲嵌橡膠墊或橡膠環(huán)的形式。像截止閥一樣,流體通過升降式止回閥的通道也是狹窄的,因此通過升降式止回閥的壓力降比旋啟式止回閥大些,而且旋啟式止回閥的流量受到的限制很少

安裝方法
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。
