style="font-size:16px;">煙道止回閥在日常生活中，又被稱為逆止閥、單向閥、逆流閥或背壓閥。止回閥屬于一種自動閥門，依靠介質(zhì)本身流動而自動開、閉閥瓣，其主要作用是防止介質(zhì)倒流、防止泵及驅(qū)動電動機(jī)反轉(zhuǎn)，以及容器介質(zhì)的泄放。在很多地方，是把這種煙道止回閥作為推廣的環(huán)保產(chǎn)品之一。如今在一棟樓里，廚房的煙道基本都是公用的。很多人在家的時候經(jīng)常會聞到樓上樓下做飯時，飄來的誘人飯菜香味，之所以產(chǎn)生這種情況的原因很多都是油煙機(jī)與煙道密封不好，而止回閥的作用就是防止廚房煙道里通過油煙機(jī)返位，阻止了油煙倒灌的作用。其實這種煙道止回閥不僅具有防止煙氣對生活產(chǎn)生的影響，還是您家庭中的寧靜衛(wèi)士，它可以有用地制止大眾煙道中他人家中排出的有毒廢氣和油煙倒灌進(jìn)入自己家里。值得強(qiáng)調(diào)的是，煙道止回閥還具有良好的防火性能，尤其是對于一些可以選擇金屬材質(zhì)的止回閥，這樣就可以更好的保證其安全性能，而且在很大程度上解決了蚊子、飛蛾、蒼蠅等蟲子的危害，可以給居家提供一個更安全、更衛(wèi)生的生活條件了。不僅如此，當(dāng)煙道內(nèi)的溫度達(dá)到150°時(煙道溫度達(dá)到150°默認(rèn)為煙道內(nèi)有明火），閥體背面的溫控元件動作，觸動關(guān)閉開關(guān)。</span><span

style="font-size:16px;">泵出口止回閥的安裝1、旋啟式止回閥一般安裝在水平管道上：對于口徑DN<80mm的止回閥，也可安裝在垂直或向上傾斜的管道上。2、直通式升降式止回閥應(yīng)安裝在水平管道上;立式升降式止回閥必須安裝在垂直管道上，介質(zhì)為自下而上流動。3、由于止回閥容易損壞，因此，應(yīng)靠近泵出口安裝止回閥，在止回閥上部設(shè)有切斷閥(一般用球閥或閘閥)，方便檢修。4、為便于止回閥拆卸前泄壓，對于止回閥本身不帶放凈閥的，應(yīng)在止回閥與切斷閥之間加裝泄壓用放凈閥。防止水力沖擊對止回閥密封面損壞的保護(hù)措施止回閥的設(shè)置，起到了防止物料倒流，避免泵葉輪遭受液擊的作用。但就止回閥本身而言，設(shè)置不當(dāng)，會造成水擊所產(chǎn)生的閥瓣對閥座的突然撞擊，損及止回閥密封面。因此，應(yīng)采取以幾點保護(hù)措施。1、對于泵出口設(shè)置>80mm的旋啟式止回閥，應(yīng)采用水平安裝方式，以減弱閥瓣回座及產(chǎn)生的撞擊。2、對于泵出口止回閥口徑大于等于150mm的管路，應(yīng)在止回閥前后設(shè)置旁路，防止閥前壓力上升過高，對止回閥密封面造成的損害。3、對泵排出管路起點和終點壓力較高管路，不允許設(shè)置旁路的，可采取以下措施：設(shè)置安全閥以代替旁路閥。其作用與旁路</span><span

style="font-size:16px;">兩種安裝方法的區(qū)別和優(yōu)勢各有哪些：具體情況要考慮產(chǎn)品的特性及安裝的方式方法來決定。止回閥的作用在我們的日常生活中還是很重要的，所以大家還是要對止回閥等各種功能、型號有個大概的認(rèn)識和了解。這樣才能在以后的維修中處理的更好，應(yīng)用的更安心。放心的產(chǎn)品要在選擇的時止回閥必須安裝在泵的出口、出口控制閥之前的位置，以便檢修止回閥。一般泵的出口道是軟連接（減震器），接下來是止回閥，再接下來是隔斷閥（如蝶閥、閘閥、截止閥等）先裝止回閥后裝閘閥或者蝶閥優(yōu)點：可以保護(hù)止回閥，特別是在并聯(lián)泵中，當(dāng)一個泵不啟動，其出口門關(guān)閉，另外一個泵啟動的時候，沖擊力都是閘閥或者蝶閥承擔(dān)。止回閥發(fā)生故障后，可以關(guān)閉進(jìn)出口閥隔離系統(tǒng)進(jìn)行修理。</span>
