用于工業(yè)管道上作阻止介質(zhì)逆流的裝置。 4. 防止介質(zhì)倒流、防止泵及驅(qū)動電動機反轉(zhuǎn)，以及容器介質(zhì)的泄放。 5. 美標電站止回閥是自動工作的，在一個方向流動的流體壓力作用下，北京900lb美標高壓止回閥價格，閥瓣打開；流體反方向流動時，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。止回閥常用作抽水裝置的底閥，可以阻止水的回流。北京900lb美標高壓止回閥價格</p><div style="width:100%;text-align: center;"><img style="max-width:

style="text-indent:25px">升降式的止回閥也分為兩種類型，一種是前部和后部呈線條型連接，這種類型為直通式，一般被應用在水平的管道中。一種是上部和下部呈線條型連接，這種類型為立式，一般被應用在豎直的管道中。對于旋啟式的止回閥來說，它和升降式的止回閥具有相似之處。雖然兩種止回閥的結(jié)構(gòu)不同，但是在介質(zhì)流通的過程中都會遇到阻力。不同旋啟式的止回閥有不同的結(jié)構(gòu)瓣，如果是單瓣的結(jié)構(gòu)，應該采用閉合的裝置，對介質(zhì)的壓力進行抵擋。如果是雙瓣的結(jié)構(gòu)，則不用再添加任何裝置，因為該結(jié)構(gòu)的重量比較小。北京900lb美標高壓止回閥價格美標止回閥的閥瓣為旋啟式，流道為直通式，水平管道、垂直管道均可安裝。</p><div

style="text-indent:25px">單瓣旋啟式止回閥一般適用于中等口徑的場合。大口徑管路選用單瓣旋啟式止回閥時，為減少水錘壓力，采用能減小水錘壓力的緩閉止回閥。雙瓣旋啟式止回閥適用于大中口徑管路。對夾雙瓣旋啟式止回閥結(jié)構(gòu)小、重量輕，是一種發(fā)展較快的止回閥；多瓣旋啟式止回閥適用于大口徑管路。電站止回閥主要安裝在介質(zhì)為汽、水的管道上，作為自動防止介質(zhì)逆流的安全裝置。電站止回閥特點：1、閥瓣能在閥體內(nèi)上下移動，當介質(zhì)倒流時，依靠介質(zhì)壓力就能將閥門自動關(guān)閉，有的閥門還裝有彈簧，來輔助閥瓣關(guān)閉。2、閥座密封面用鈷基硬質(zhì)合金等離子噴焊而成，所以密封面硬度高、抗擦傷、耐摩擦、使用壽命長。3、DN50，PN20~25閥體、閥蓋為模鍛，閥瓣為整體淬火。4、DN50，PN10以及DN50以上的閥門的閥體、閥蓋為鑄造，閥瓣密封面堆焊鈷基硬質(zhì)合金。</p><p style="text-indent:25px">2、國標止回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向套簡，閥瓣導向簡可在閥盞導向簡內(nèi)自由升降，當介質(zhì)順流時，閥瓣靠介質(zhì)推力開啟，當介質(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。美標止回閥是指依靠介質(zhì)本身流動而自動開、閉閥瓣，用來防止介質(zhì)倒流的閥門，又稱逆止閥。</p><div
