style="font-size:16px;">消聲止回閥主要適用于高層建筑供水、排水系統(tǒng)，消防管道給水系統(tǒng)等。此消聲止回閥可有效地防止介質(zhì)倒流而產(chǎn)生破壞性水錘，保護(hù)水泵和管道其它設(shè)備。1、閥瓣采用頭”外形設(shè)計(jì)，閥體采用“腰鼓”外形設(shè)計(jì)，改善介質(zhì)流向，降低流阻系數(shù)。2、閥門采用短結(jié)構(gòu)形式，雖然水頭損失比升降式靜音止回閥稍大些，但體積小、價(jià)格便宜。3、結(jié)構(gòu)緊湊，導(dǎo)向軸與導(dǎo)向架之間裝有非金屬潤滑套，閥瓣升降靈活，不會產(chǎn)生抱死現(xiàn)象。4、骨架式橡膠密封圈直接鑲嵌在閥體上，避免了介質(zhì)長時(shí)間對密封圈的直接沖刷，使用壽命明顯延長，堅(jiān)固、耐用。5、閥瓣啟閉行程短，山丹止回閥廠家價(jià)格，可以有效的防止水錘產(chǎn)生。6、適用于給排水系統(tǒng)，山丹止回閥廠家價(jià)格，高層建筑管網(wǎng)，可安裝在泵的出口處，結(jié)構(gòu)稍加改動(dòng)，山丹止回閥廠家價(jià)格，可做為吸水底閥使用，但不適用于污水管網(wǎng)。</span> 安裝止回閥是為了保證水泵內(nèi)部水流的流向，從而保障水泵的正常工作。山丹止回閥廠家價(jià)格</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="山丹止回閥廠家價(jià)格,止回閥"

style="font-size:16px;">止回閥過大會導(dǎo)致流速低，從而無法保持閥門始終打開。這會導(dǎo)致不穩(wěn)定，閥可能會顫動(dòng)或顫動(dòng)。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(dǎo)致的其他系統(tǒng)停機(jī)，這會導(dǎo)致閥門過早的機(jī)械磨損以及可能帶來的額外維護(hù)成本。止回閥尺寸過小會導(dǎo)致通過該閥的流量過高，從而導(dǎo)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(dǎo)致閥不穩(wěn)定并增加機(jī)械磨損，從而導(dǎo)致更高的維護(hù)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(jì)算壓力損失。對于水，Cv是壓差為1psi（lb/平方英寸）時(shí)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(shí)。</span>

style="font-size:16px;">旋轉(zhuǎn)式止回閥運(yùn)用的范圍通常比較廣，無論是水平的或者垂直的都完全可以勝任，但需要注意的是如果安裝在垂直系統(tǒng)中的時(shí)候，流體的流動(dòng)方向必須是自下而上的流動(dòng)；8、紅河州冷凍庫工程安裝建造廠家云南寒功制冷設(shè)備有限公司敬告您：旋轉(zhuǎn)式止回閥通常情況下不應(yīng)該做成小口徑的閥門，與此同時(shí)就可以承載比較大的工作壓力。大多數(shù)止回閥通常都比較適用于低壓的大口徑狀態(tài)，同時(shí)他們的安裝場合基本上都有一定的限制；10、和立式升降止回閥相似碟式止回閥的安裝位置也基本上不受限制，無論是水平或者垂直的管路上都同樣有效；11、對于一些容易產(chǎn)生水擊的管路上面，用隔膜式止回閥是一個(gè)不錯(cuò)的選擇。他可以有效的減少流體在逆流時(shí)產(chǎn)生的水擊，因此在自來水管道上隔膜式止回閥的運(yùn)用比較多；12、在中低壓管</span><span style="font-size:16px;">路中</span><span style="font-size:16px;">球型止回閥有無可比擬的優(yōu)勢，同時(shí)它還可以被制造成大口徑，因此其匹配也非常的簡單。</span> </p><p> <span style="font-size:16px;">碟式止回閥：閥瓣圍繞閥座內(nèi)的銷軸旋轉(zhuǎn)的止回閥。碟式止回閥結(jié)構(gòu)簡單，只能安裝在水平管道上，密封性較差。四、管道式止回閥：閥瓣沿著閥體中心線滑動(dòng)的閥門。管道式止回閥是新出現(xiàn)的一種閥門，它的體積小，重量較輕，加工工藝性好，是止回閥發(fā)展方向之一。但流體阻力系數(shù)比旋啟式止回閥略大。壓緊式止回閥：這種閥門是做為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(jī)能。此外，還有些不適用于泵出口安裝的止回閥，如底閥、彈簧式，Y型等。止回閥又叫逆止閥，是一種自動(dòng)閥門。它依靠管道內(nèi)流動(dòng)介質(zhì)的壓力推動(dòng)閥瓣，來實(shí)現(xiàn)閥門的關(guān)閉和開啟，當(dāng)介質(zhì)停止流動(dòng)，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。</span>

style="font-size:16px;">止回閥是*允許介質(zhì)沿一個(gè)方向流動(dòng)的裝置，閥瓣依靠自身重量及介質(zhì)壓力產(chǎn)生動(dòng)作，實(shí)現(xiàn)阻斷介質(zhì)倒流的一種閥門。它根據(jù)系統(tǒng)中的壓力自動(dòng)工作，運(yùn)行中不需要用戶或執(zhí)行裝置來干預(yù)，屬于自動(dòng)閥類。又稱為逆止閥、單向閥、回流閥或隔離閥。按結(jié)構(gòu)分為升降式、旋啟式和蝶式止回閥。主要作用：防止介質(zhì)倒流、防止水泵反轉(zhuǎn)、防止容器內(nèi)的介質(zhì)泄露。升降式止回閥的閥瓣沿著閥體垂直中心線動(dòng)作，結(jié)構(gòu)與截止閥類似，但只有閥瓣，而沒有人為旋起的閥桿。介質(zhì)從進(jìn)口端(下側(cè))流入，從出口端(上側(cè))流出。當(dāng)進(jìn)口壓力大于閥瓣重量及其流動(dòng)阻力之和時(shí)，閥門被開啟。反之，介質(zhì)倒流時(shí)閥門則關(guān)閉。工作原理：旋啟式止回閥的閥瓣繞閥座通道里的轉(zhuǎn)軸做旋轉(zhuǎn)運(yùn)動(dòng)，順流時(shí)閥瓣打開，有逆向流動(dòng)時(shí)閥瓣關(guān)閉。適用于低</span><span
