style="font-size:16px;">法蘭式橡膠瓣止回閥主要用于臥式安裝于給排水系統(tǒng)，可安裝于水泵出水口處、以防止倒流及水錘對(duì)泵的損害，還可安裝在蓄水池進(jìn)出水管的旁通管上，以防止池水倒流至給水系統(tǒng)中。閥門中的橡膠瓣由鋼板、鋼棒及強(qiáng)化尼龍布做襯底，外層披覆橡膠制成，閥瓣開(kāi)關(guān)壽命可達(dá)100萬(wàn)次，采用全流面積設(shè)計(jì)，具有水頭損失小，不易堆積雜物，維修簡(jiǎn)便等特性。旋啟式止回閥有一個(gè)斜置并能繞軸旋轉(zhuǎn)的閥瓣，工作原理與升降式止回閥相似。止回閥常用作抽水裝置的底閥，可以阻止水的回流。止回閥與截止閥組合使用，海原止回閥聯(lián)系方式，可起到安全隔離的作用。缺點(diǎn)是阻力大，關(guān)閉時(shí)密封性差。止回閥這種類型的閥門的作用是只允許介質(zhì)向一個(gè)方向流動(dòng)，海原止回閥聯(lián)系方式，而且阻止反方向流動(dòng)。通常這種閥門是自動(dòng)工作的，在一個(gè)方向流動(dòng)的流體壓力作用下，海原止回閥聯(lián)系方式，閥瓣</span><span

style="font-size:16px;">兩種安裝方法的區(qū)別和優(yōu)勢(shì)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(lái)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(duì)止回閥等各種功能、型號(hào)有個(gè)大概的認(rèn)識(shí)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(shí)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(lái)是止回閥，再接下來(lái)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(diǎn)：可以保護(hù)止回閥，特別是在并聯(lián)泵中，當(dāng)一個(gè)泵不啟動(dòng)，其出口門關(guān)閉，另外一個(gè)泵啟動(dòng)的時(shí)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>
