截止止回閥（stop-checkvalve）兼有截止閥和止回閥功能的多用閥門。它的結(jié)構(gòu)形式與截止閥相似，但閥桿與閥瓣不是固定聯(lián)接。當(dāng)閥桿下降將閥瓣緊壓在閥座上時，起截止閥作用；閥桿上升后，則起止回閥作用。在同時需要安裝截止閥(或閘閥)和止回閥的管道上（如水泵的出口端），或在安裝位置受到限制的場所（如船舶），使用截止止回閥可節(jié)約安裝費(fèi)用和空間位置。中文名截止止回閥外文名stop-checkvalve性質(zhì)多用閥門功能兼有截止閥和止回閥功能目錄1結(jié)構(gòu)特點(diǎn)2標(biāo)準(zhǔn)與規(guī)范3選用要求截止止回閥結(jié)構(gòu)特點(diǎn)編輯截止的閥瓣、閥座密封面堆焊鐵基合金或司太立鈷基硬質(zhì)合金，具有耐磨、耐截止止回閥高溫、耐腐蝕、抗擦傷性能好、使用壽命長的特點(diǎn)。截止止回多用閥（多功能止回閥）產(chǎn)品可適用于石油、化工、制藥、電力行業(yè)等各種工況的水平安裝管路上。截止止回閥標(biāo)準(zhǔn)與規(guī)范編輯設(shè)計(jì)與制造：GB12235結(jié)構(gòu)長度：GB12221壓力-溫度等級：GB9131、JB/T74、HG20604連接法蘭：JB/T79、GB9113、HG20592試驗(yàn)與檢驗(yàn)：JB/T9092、GB13927截止止回閥選用要求編輯截止閥是指關(guān)閉件(閥瓣)沿閥座中心線移動的閥門。根據(jù)閥瓣的這種移動形式，閥座通口的變化是與閥瓣行程成正比例關(guān)系。</p><p> 止回閥的分類止回閥根據(jù)其結(jié)構(gòu)和安裝方式可分：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，因閥內(nèi)通道成流線形，流動阻力比升降式止回閥小，適用于低流速和流動不常變化的大口徑場合，但不宜用于脈動流，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)停止流動或倒流時，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，閥瓣導(dǎo)向簡可在閥盞導(dǎo)向簡內(nèi)自由升降，當(dāng)介質(zhì)順流時，閥瓣靠介質(zhì)推力開啟，當(dāng)介質(zhì)停流時，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，其流動阻力較直通式小。三、碟式止回閥：閥瓣圍繞閥座內(nèi)的銷軸旋轉(zhuǎn)的止回閥。碟式止回閥結(jié)構(gòu)簡單。江蘇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

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，閥瓣導(dǎo)向簡可在閥盞導(dǎo)向簡內(nèi)自由升降，當(dāng)介質(zhì)順流時，閥瓣靠介質(zhì)推力開啟，當(dāng)介質(zhì)停流時，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，其流動阻力較直通式小。三、碟式止回閥：閥瓣圍繞閥座內(nèi)的銷軸旋轉(zhuǎn)的止回閥。碟式止回閥結(jié)構(gòu)簡單，只能安裝在水平管道上，密封性較差。四、管道式止回閥：閥瓣沿著閥體中心線滑動的閥門。管道式止回閥是新出現(xiàn)的一種閥門，它的體積小，重量較輕，加工工藝性好，是止回閥發(fā)展方向之一。但流體阻力系數(shù)比旋啟式止回閥略大。五、壓緊式止回閥：這種閥門是做為鍋爐給水和蒸汽切斷用閥，它具有升降式止回閥和截止閥或角閥的綜合機(jī)能。此外，還有些不適用于泵出口安裝的止回閥。浙江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。黃山雙板高壓緩沖止回閥</p><p

12、球形止回閥適用于中低壓管路，可以制成大口徑；13、球形止回閥的殼體材料可以用不銹鋼制作，密封件的空心球體可以包裹聚四氟乙烯工程塑料，所以在一般腐蝕性介質(zhì)的管路上也可應(yīng)用，工作溫度在-101--150℃之間，其公稱壓力≤，公稱通經(jīng)范圍在DN200—DN1200之間；14、對于不可壓縮性流體用止回閥選擇時首先要對所需要的關(guān)閉速度進(jìn)行評估，第二步是選擇可能滿足所需要的關(guān)閉速度的止回閥的類型；15、對于可壓縮性流體用止回閥選擇時可以根據(jù)不可壓縮性流體用止回閥的類似方法來進(jìn)行選擇，如果介質(zhì)流動范疇很大，則用于可壓縮性流體的止回閥可使用一減速裝置，如果介質(zhì)流連續(xù)不段地快速停止和啟動，如壓縮機(jī)的出口那樣，則使用升降式止回閥；16、止回閥應(yīng)確定相應(yīng)的尺寸，閥門供應(yīng)商必須提供選定尺寸的資料數(shù)據(jù)，這樣就能找到給定流速下閥門全開時的閥門尺寸大小；17、對于DN50mm以下的高中壓止回閥，宜選用立式升降止回閥和直通式升降止回閥；18、對于DN50mm以下的低壓止回閥，宜選用蝶式止回閥、立式升降止回閥和隔膜式止回閥；19、對于DN大于50mm、小于600mm的高中壓止回閥，宜選用旋啟式止回閥；20、對于DN大于200mm、小于1200mm的中低壓止回閥。景德鎮(zhèn)雙瓣旋啟式止回閥</p><p
