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2標準與規(guī)范3選用要求截止止回閥結(jié)構(gòu)特點編輯截止的閥瓣、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，雙瓣旋啟式止回閥批發(fā)。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。截止止回閥標準與規(guī)范編輯設(shè)計與制造：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試驗與檢驗：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。寧波鼎力閥門是一家專門生產(chǎn)制造銷售止回閥的公司，雙瓣旋啟式止回閥批發(fā)，主要有靜音止回閥，雙瓣旋啟式止回閥批發(fā)，對夾蝶形止回閥，消聲止回閥。雙瓣旋啟式止回閥批發(fā)</p><div

蝶式止回閥分單瓣式、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。2、靜音止回閥：閥瓣沿著閥體垂直中心線滑動的止回閥，內(nèi)螺紋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。蝶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。直通式蝶式止回閥介質(zhì)進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。3、靜音止回閥：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，密封性較好。4、靜音止回閥：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。5、壓緊式止回閥：這種閥門是做為鍋爐給水和蒸汽切斷用閥。朝陽止回閥生產(chǎn)廠家紹興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，對夾蝶形止回閥，消聲止回閥。</p><div
