style="font-size:16px;">隨著我國社會經(jīng)濟建設的快速發(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;">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、型號有個大概的認識和了解。這樣才能在以后的維修中處理的更好，應用的更安心。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：可以保護止回閥，特別是在并聯(lián)泵中，當一個泵不啟動，其出口門關閉，另外一個泵啟動的時候，沖擊力都是閘閥或者蝶閥承擔。止回閥發(fā)生故障后，可以關閉進出口閥隔離系統(tǒng)進行修理。</span> </p><p> <span style="font-size:16px;">倒流防止器和止回閥的區(qū)別1，功能方面倒流防bai止器主要用于防止水的回du流，即使其內(nèi)部所有可能的密封全部失效,仍能確保不發(fā)生dao回流污染事故.是保障水質(zhì)的**技術措施.止回閥主要用于保證水的單向流動，防止水倒流.但無防污性能,當止回密封面失效，不能有效防止水的回流污染。設有倒流防止器的管段,不需要再設止回閥；反之不能替代。2，結構方面止回閥只有單級止回密封結構,結構長度小,自重輕減壓型倒流防止器包含有兩個**止回密封+自動感應的泄水器,體長質(zhì)重.低阻力倒流防止器包含兩級止回密封+**式自動泄水器，外形小,自重輕3，水頭損失方面止回閥的水頭損失一般小于；減壓型倒流防止器的水頭損失:一般在。為低壓隔斷形式，如果水損過低,隔斷安全性將無法保證；低阻力倒流防止器的水頭損失小于。</span>

src="https://tyunfile.71360.com/UploadFile/gscyhwz/637318024352636718/6696423.png"></div><p> <span style="font-size:16px;">止回閥過大會導致流速低，從而無法保持閥門始終打開。這會導致不穩(wěn)定，閥可能會顫動或顫動。反過來，由于頻繁地更換閥門/閥芯，以及由于修理或更換止回閥而導致的其他系統(tǒng)停機，這會導致閥門過早的機械磨損以及可能帶來的額外維護成本。止回閥尺寸過小會導致通過該閥的流量過高，從而導致系統(tǒng)中不必要的高壓力損失。它還可能在流中產(chǎn)生過度的湍流，這可能導致閥不穩(wěn)定并增加機械磨損，從而導致更高的維護成本。同樣，通過尺寸過小的閥門的較高流速可能會增加閥門內(nèi)部的腐蝕磨損。閥門的流量系數(shù)Cv用于計算壓力損失。對于水，Cv是壓差為1psi（lb/平方英寸）時的流量，單位為gpm（gal/min）。對于SI單位，Kv是相似的流量系數(shù)：對于水，壓差為1bar時。</span>

style="font-size:16px;">倒流防止器和止回閥是消防行業(yè)內(nèi)比較常見的兩個概念，字面意思來看兩者的作用都是防止介質(zhì)回流、強制單向流動，但是對于兩者的關系，初學者大多有點模糊不清。首先對兩者的定義作一個簡單的介紹：止回閥：又稱單向閥或者逆止閥，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。倒流防止器：一種采用止回部件組成的可防止給水管道水流倒流的裝置單從定義來看，很難發(fā)現(xiàn)兩者有何不同，“中成教育”從構造、作用和設置的部位等3個方面來對比二者的區(qū)別。止回閥：主要用于保證介質(zhì)的單向流動，防止介質(zhì)倒流.但無防污性能,當止回密封面失效，不能有效防止介質(zhì)的回流污染。2、倒流防止器：防止介質(zhì)的回流（即使其內(nèi)部所有可能的密封全部失效,仍能確保不發(fā)生回流污染事故），防止上下游的介質(zhì)發(fā)生接觸</span><span
