style="font-size:16px;">閉止回閥緩閉止回閥是一種通過增加執(zhí)行機構(gòu)、阻尼器而實現(xiàn)緩慢關(guān)閉的止回閥。緩閉止回閥需要配合開關(guān)閥使用。當介質(zhì)在重力作用下倒流時，止回閥緩慢關(guān)閉，有效地避免了因普通止回閥突然關(guān)閉產(chǎn)生的水錘。其缺點為因為關(guān)閉速度較慢，一部分介質(zhì)不可避免地倒流進入離心泵，泵因此可能會產(chǎn)生機械故障。2、設(shè)置緩閉止回蝶閥這是一種在大型水利系統(tǒng)中應(yīng)用比較普遍、效果比較好的方法。緩閉止回蝶閥由蝶閥、執(zhí)行結(jié)構(gòu)及液壓控制系統(tǒng)構(gòu)成。該系統(tǒng)只需安裝緩閉止回蝶閥即可，即能起到止回閥的作用又能起到開關(guān)閥的作用。當離心泵開啟的時候，其按先慢后快的步驟開啟，保證泵低載開啟;當泵突然停止工作時，其按先快后慢的步驟關(guān)閉，即可以避免水錘的產(chǎn)生，又可以避免過多的介質(zhì)倒流通過泵，引起泵的機械故障。</span>

</p><p> <span style="font-size:16px;">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、單向閥、逆流閥、和背壓閥。止回閥屬于一種自動閥門，其主要作用是防止介質(zhì)倒流、防止泵及驅(qū)動電動機反轉(zhuǎn)，以及容器介質(zhì)的泄放止回閥根據(jù)其結(jié)構(gòu)和安裝方式主要分為：升降式止回閥、旋啟式止回閥、蝶式止回閥、管道式止回閥和壓緊式止回閥。作為配管專業(yè)當然就是要考慮止回閥的安裝方式</span><span style="font-size:16px;">了。止回閥的安裝要求：1.升降式止回閥，閥瓣是沿著閥體垂直中心線滑動的止回閥，閥門型號是H41——，升降式止回閥只能安裝在水平管道上。2.旋啟式止回閥，閥瓣是圍繞閥座外的銷軸旋轉(zhuǎn)的止回閥，閥門型號是H44——，水平和垂直管道都可以，只是安裝方向有要求。不過比較好還是水平安裝，當然對于介質(zhì)流動方向為從下到上的，也可以垂直安裝。3.碟式止回閥，閥瓣圍繞閥座內(nèi)的銷軸旋轉(zhuǎn)，閥門型號是H45——，碟式止只能安裝在水平管道上。4.管道式止回閥，它的閥瓣是沿著閥體中心線滑動的閥門，水平和垂直方向都可以，但是也是需要注意安裝方向的。5.壓緊式止回閥：一般是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能，也是需要水平安裝。</span>
