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，閥瓣開關(guān)壽命可達(dá)100萬次，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，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)，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，閥瓣</span><span

style="font-size:16px;">有哪些判斷標(biāo)準(zhǔn)來選擇適合的止回閥1、止回閥被大量運(yùn)用主要是為了阻止流質(zhì)的逆向流動(dòng)。在一些特定的設(shè)備和管道上如果需要流質(zhì)單向的流動(dòng)則應(yīng)該加裝止回閥；2、止回閥的適用范圍一般都是比較干凈清潔的流體，不適用于粘度大以及含有固體顆粒和污水的流體系統(tǒng)當(dāng)中；3、立式升降止回閥一般都用于管徑在5cm左右的水平管道上；4、相對(duì)于立式升降止回閥而言直通式升降止回閥不僅可以運(yùn)用于水平管道上，在垂直管道中也得到了大量的運(yùn)用；底閥在大多數(shù)情況下都是用于泵進(jìn)口的垂直管道上的，所以如果是水泵的進(jìn)口管路一般都用底閥，并且通常情況而言流體都是從下往上流動(dòng)的情況；6、對(duì)于升降式旋轉(zhuǎn)止回閥而言它擁有良好的密封性，這是其他止回閥無法比擬的，但是它的運(yùn)用范圍要小很多，一般臥式的都安裝在水</span><span
