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入自己家里。值得強調(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，當煙道內(nèi)的溫度達到150°時(煙道溫度達到150°默認為煙道內(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;">隨著我國社會經(jīng)濟建設(shè)的快速發(fā)展，人們的生活質(zhì)量不斷提高，對居住區(qū)周邊的環(huán)境也越來越重視，噪聲污染就是影響環(huán)境的重要來源之一。噪聲污染是繼大氣污染和水污染之后的第三大污染來源，其中建筑內(nèi)部的噪聲為嚴重。建筑內(nèi)部噪聲來源分為兩種，一種是常用的家用電器，比如電視、空調(diào)等，另外一種來自建筑給水排水系統(tǒng)產(chǎn)生的噪聲。由于建筑施工、給水管道、排水管道和水泵自身的機械振動等原因，室內(nèi)的噪聲環(huán)境愈加嚴重。根據(jù)《民用建筑隔聲設(shè)計規(guī)范》(GBJ118-88)規(guī)定：夜間臥室噪聲不得超過30db，比較高不得超過40db。但給水排水系統(tǒng)所產(chǎn)生的噪聲遠遠超過規(guī)范標準，嚴重影響到建筑內(nèi)部和周邊居民的休息質(zhì)量，嚴重情況下可能導致人們產(chǎn)生神經(jīng)衰弱癥。因此，如何控制建筑給水排水系統(tǒng)噪聲成為</span><span

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>

style="font-size:16px;">止回閥又叫逆止閥，是一種自動閥門，它依靠管道內(nèi)流動介質(zhì)的壓力推動閥瓣，來實現(xiàn)閥門的關(guān)閉和開啟，當介質(zhì)停止流動，止回閥閥瓣關(guān)閉，它能有效防止管道內(nèi)介質(zhì)發(fā)生倒流，這對于保障管道的安全起到了很大的作用。一種是安裝在水泵前豎吸管端頭，也叫底閥。目的是為了不用抽一次水向水泵充一次水，因為水泵內(nèi)以及泵前的吸管內(nèi)無水時水泵只能空轉(zhuǎn)抽不上水，所以水泵內(nèi)必須充滿水才能抽出水。這種水泵的安裝是高于液面時的一種方法，也叫負壓法。另一種是安裝在水泵的后方。這種安裝方法是液面高于水泵的情況下，方便啟停水泵時不用關(guān)水泵出水閥，特別是對于母管制水泵系統(tǒng)，防止發(fā)生倒流的情況。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</span><span
