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
