止回閥主要是用來防止管道中的介質(zhì)倒流使用。底閥及鴨嘴閥也是屬于止回閥系類。止回閥可分為升降式、旋啟式、碟型三種： ⑴升降式又分為立式和臥式2種，升降式結(jié)構(gòu)是沿軸線移動(dòng)。實(shí)例：①升降式靜音止回閥是用在給排水工程質(zhì)量要求高的管線上；同時(shí)可安裝在泵的出口處，要求壓力（PN2.5Mpa）相對高的管網(wǎng)，山東止回閥廠商有哪些，是防水沖擊止回閥的重要產(chǎn)品。 ②升降式消聲止回閥適用于高層建筑給排水系統(tǒng)中及泵的出口處，不適合污水管路場合。 ③臥式止回閥適用于潛水、排水、排污泵，特別適用于污水和污泥系統(tǒng)。 ⑵旋啟式分為單瓣式、雙瓣式和多瓣式，山東止回閥廠商有哪些，選啟式結(jié)構(gòu)是依據(jù)重心旋轉(zhuǎn)，山東止回閥廠商有哪些。如果您的止回閥頻頻出現(xiàn)問題，可能是挑選不妥造成的。山東止回閥廠商有哪些</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

那么止回閥的安裝位置如何確定呢？泵前安裝與泵后安裝止回閥有何區(qū)別，泵前安裝適用于哪些地方？止回閥通常要配合其他閥門一起使用，那么跟其他閥門配合使用時(shí)，止回閥要安裝在哪里呢？下面我們來一起探討一下。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。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。云南止回閥哪家便宜止回閥主要可分為旋啟式止回閥與升降式止回閥（沿軸線移動(dòng)）。</p><div

style="text-indent:25px">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。另一種是安裝在水泵的后方。這種安裝方法是液面高于水泵的情況下，方便啟停水泵時(shí)不用關(guān)水泵出水閥，特別是對于母管制水泵系統(tǒng)，防止發(fā)生倒流的情況。</p><p style="text-indent:25px">止回閥開啟是指依靠介質(zhì)正向流動(dòng)打開閥瓣，同樣的道理介質(zhì)倒流推動(dòng)閥瓣而關(guān)閉，止回閥還稱之為逆止閥、單向閥、逆流閥和背壓閥。多屬于自動(dòng)閥門，主要功能是用來防止介質(zhì)倒流，防止泵及驅(qū)動(dòng)電機(jī)反轉(zhuǎn)和容器介質(zhì)的泄放使用。同時(shí)還用于壓力可能升至超過系統(tǒng)壓的輔助系統(tǒng)中作安全保護(hù)。止回閥的啟閉是依靠介質(zhì)流動(dòng)力量自行開啟和關(guān)閉。止回閥屬于自動(dòng)閥產(chǎn)品，止回閥只允許介質(zhì)向一個(gè)方向流動(dòng)的管路中使用，防止介質(zhì)回流的現(xiàn)象發(fā)生。其使用范圍普遍，可適用大小口徑、各種介質(zhì)、電站高壓系統(tǒng)中使用。止回閥可分為升降式、旋啟式、碟型三種。</p><div

1、為了防止介質(zhì)逆流，在設(shè)備、裝置和管道上都應(yīng)安裝止回閥； 2、止回閥一般適用于清凈介質(zhì)，不宜用于含有固體顆粒和粘度較大的介質(zhì)； 3、一般在公稱通徑50mm的水平管道上都應(yīng)選用臥式升降止回閥； 4、直通式升降止回閥只能在水平管道安裝； 5、對于水泵進(jìn)口管路，宜選用底閥，底閥一般只安裝在泵進(jìn)口的垂直管道上，并且介質(zhì)自下而上流動(dòng)； 6、升降式較旋啟式密封性好，流體阻力大，臥式宜裝在水平管道上，立式裝在垂直管道上； 7、旋啟式止回閥的安裝位置不受限制，它可裝在水平、垂直或傾斜的管線上，如裝在垂直管道上，介質(zhì)流向要由下而上； 8、旋啟式止回閥不宜制成小口徑閥門、可以做成很高的工作壓力，公稱壓力可達(dá)到42MPa，而且公稱通徑也可以做到很大，較大可以達(dá)到2000mm以上。根據(jù)殼體及密封件的材質(zhì)不同可以適用任何工作介質(zhì)和任何工作溫度范圍。介質(zhì)為水、蒸汽、氣體、腐蝕性介質(zhì)、油品、藥品、等。介質(zhì)工作溫度范圍在-196--800℃之間。為了防止介質(zhì)逆流，在設(shè)備、裝置和管道上都應(yīng)安裝止回閥。云南止回閥哪家便宜</p><p
