止回閥這種類型的閥門的作用是只允許介質(zhì)向一個(gè)方向流動(dòng)，而且阻止反方向流動(dòng)。通常這種閥門是自動(dòng)工作的，在一個(gè)方向流動(dòng)的流體壓力作用下，閥瓣打開；流體反方向流動(dòng)時(shí)，由流體壓力和閥瓣的自重合閥瓣作用于閥座，從而切斷流動(dòng)。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、范圍廣的與閥座接觸。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。旋啟式止回閥在完全打開的狀況***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。漳州對(duì)夾單瓣旋啟式止回閥義烏鼎力閥門是一家專門生產(chǎn)制造銷售止回閥的公司，主要有靜音止回閥，對(duì)夾蝶形止回閥，消聲止回閥。</p><div

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口徑來分，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。</p><p> 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，只有缺少帶動(dòng)閥瓣的閥桿。介質(zhì)從進(jìn)口端(下側(cè)）流入，從出口端（上側(cè)）流出。當(dāng)進(jìn)口壓力大于閥瓣重量及其流動(dòng)阻力之和時(shí)，閥門被開啟。反之，介質(zhì)倒流時(shí)閥門則關(guān)閉。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。[1]中文名止回閥外文名checkvalve；refluxvalve設(shè)備類型閥門功能介質(zhì)單向流動(dòng)、防倒流分類升降式、旋啟式、蝶式常見故障閥瓣打碎、介質(zhì)倒流等目錄1工作原理2分類?結(jié)構(gòu)分類?材質(zhì)分類?功能分類3安裝?安裝方法?注意事項(xiàng)4止回閥性能參數(shù)5標(biāo)準(zhǔn)6工藝設(shè)計(jì)7選型標(biāo)準(zhǔn)8故障處理?閥瓣打碎?介質(zhì)倒流9行業(yè)發(fā)展止回閥工作原理編輯止回閥還可用于給其中的壓力可能升至超過系統(tǒng)壓的輔助系統(tǒng)提供補(bǔ)給的管路上。止回閥主要可分為旋啟式止回閥（依重心旋轉(zhuǎn)）與升降式止回閥（沿軸線移動(dòng)）。金華鼎力閥門是一家專門生產(chǎn)制造銷售止回閥的公司，主要有雙瓣旋啟式止回閥，耐腐蝕緩沖止回閥等。</p><div
