style="text-indent:25px">止回閥按結(jié)構(gòu)劃分，可分為升降式止回閥、旋啟式止回閥和蝶式止回閥三種。升降式止回閥可分為立式和直通式兩種。旋啟式止回閥分為單瓣式、雙瓣式和多瓣式三種。蝶式止回閥分為蝶式雙瓣、蝶式單瓣，以上幾種止回閥在連接形式上可分為螺紋連接、法蘭連接、焊接和對夾式連接四種。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。所以關(guān)于止回閥的安裝位置，到底是安裝在水泵前還是水泵后，可以分兩種情況：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?yàn)樗脙?nèi)以及泵前的吸管內(nèi)無水時(shí)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(shí)的一種方法，也叫負(fù)壓法。止回閥是指啟閉件為圓形閥瓣并靠自身重量及介質(zhì)壓力產(chǎn)生動作來阻斷介質(zhì)倒流的一種閥門。甘肅止回閥廠家直銷</p><p style="text-indent:25px">止回閥是指依靠介質(zhì)本身流動而自動開、閉閥瓣，用來防止介質(zhì)倒流的閥門。甘肅止回閥廠家直銷</p><p style="text-indent:25px"> 止回閥的閥瓣或閥芯，在水流停止流動時(shí)，應(yīng)能在重力或彈簧力作用下自行關(guān)閉。也就是說重力或彈簧力的作用方向與閥瓣或閥芯的關(guān)閉運(yùn)動的方向要一致，才能使閥瓣或閥芯關(guān)閉。一般來說臥式升降式止回閥和阻尼緩閉止回閥及多功能閥只能安裝在水平管上，立式升降式止回閥不能安裝在水平管上，其他的止回閥均可安裝在水平管上或水流方向自下而上的立管上。水流方向自上而下的立管，不應(yīng)安裝止回閥。因?yàn)檫@種情況下止回閥的閥瓣不能自行關(guān)閉，起不到止回的作用。重要的是，止回閥閥體止回方向不要弄錯(cuò)了，應(yīng)與水流流動方向一致，否則就會導(dǎo)致該止回的管路未止回，該供水的管路卻沒水！甘肅止回閥廠家直銷</p><p
