style="font-size:16px;">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。安裝位置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：1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的一種方法，也叫負(fù)壓法。</span>

style="font-size:16px;">依靠介質(zhì)本身的流動自動開，閉閥瓣，介質(zhì)只能單向流動，可防介質(zhì)倒流的閥門叫止回閥。止回閥常用的分為兩種類型:升降式止回閥，旋啟式止回閥。裝置壓濾機(jī)濾餅洗滌泵出口止回閥就屬旋啟止回閥，出現(xiàn)過因閥門兩處連接件腐蝕而不能自由開啟，歸位，造成機(jī)泵運(yùn)行出口震動大，打不起流量停車檢修。壓濾機(jī)濾餅洗滌泵止回閥故障主要是閥瓣連接件腐蝕、搖臂連接件腐蝕，造成閥瓣直接沖頂出口。通過拆除閥蓋連接螺栓，取出兩處連接螺栓并更換而修復(fù)了止回閥。機(jī)泵出口安裝止回閥主要是防止機(jī)泵停車后介質(zhì)倒流形成水錘對機(jī)泵產(chǎn)生影響。止回閥結(jié)構(gòu)簡單易修理，對于經(jīng)常自動啟停的機(jī)泵應(yīng)安裝止回閥，防止葉輪背帽因反轉(zhuǎn)松動，造成機(jī)泵運(yùn)行震動大，葉輪脫落磨蝕泵殼穿孔，更甚者造成斷軸故障停車。</span>
