止回閥又稱止逆閥、單流閥、單向閥或逆止閥，其作用是保證管路中的介質(zhì)定向流動而不致倒流。止回閥的啟閉是依靠介質(zhì)流動力量自行開啟和關(guān)閉。止回閥屬于自動閥產(chǎn)品，止回閥只允許介質(zhì)向一個方向流動的管路中使用，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。止回閥開啟是指依靠介質(zhì)正向流動打開閥瓣，同樣的道理介質(zhì)倒流推動閥瓣而關(guān)閉，止回閥還稱之為逆止閥、單向閥、逆流閥和背壓閥。多屬于自動閥門，主要功能是用來防止介質(zhì)倒流，防止泵及驅(qū)動電機反轉(zhuǎn)和容器介質(zhì)的泄放使用。同時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。</p><p style="text-indent:25px">止回閥還可用于給其中的壓力可能升至超過系統(tǒng)壓的輔助系統(tǒng)提供補給的管路上。止回閥主要可分為旋啟式止回閥（依重心旋轉(zhuǎn)）與升降式止回閥（沿軸線移動）。止回閥這種類型的閥門的作用是只允許介質(zhì)向一個方向流動，而且阻止反方向流動。通常這種閥門是自動工作的，在一個方向流動的流體壓力作用下，閥瓣打開；流體反方向流動時，由流體壓力和閥瓣的自重合閥瓣作用于閥座，從而切斷流動。其中止回閥就屬于這種類型的閥門，它包括旋啟式止回閥和升降式止回閥。旋啟式止回閥有一介鉸鏈機構(gòu)，還有一個像門一樣的閥瓣自由地靠在傾斜的閥座表面上。為了確保閥瓣每次都能到達閥座面的合適位置，閥瓣設(shè)計在鉸鏈機構(gòu)，以便閥瓣具有足夠有旋啟空間，并使閥瓣真正的、多方面的與閥座接觸。其結(jié)構(gòu)與截止閥相似，閥體和閥瓣與截止閥相同。</p><div

止回閥又叫逆止閥，是一種自動閥門。它依靠管道內(nèi)流動介質(zhì)的壓力推動閥瓣，來實現(xiàn)閥門的關(guān)閉和開啟，當介質(zhì)停止流動，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。止回閥的開啟壓力一般大于開啟后水流正常流動時的局部水頭損失。福建止回閥價錢多少</p><p

style="text-indent:25px">止回閥是引導(dǎo)水流單向流動、防止水倒流的閥門，止回閥的啟閉件靠水流流動和力量自行開啟或關(guān)閉，屬于自動閥類。在管網(wǎng)較小壓力或水箱較低有效水位時，應(yīng)仍能保證止回閥的開啟。止回閥的開啟壓力一般大于開啟后水流正常流動時的局部水頭損失。根據(jù)國標圖集01SS105，止回閥的較小開啟壓力有0.003Mpa、0.01Mpa等；根據(jù)建水標第3.5.7條的條文解釋，旋啟式止回閥在靜水壓大于或等于0.5m時可開啟。故在設(shè)計制圖時，應(yīng)保證管網(wǎng)較小壓力及水箱較低有效水位必須大于所選止回閥的較小開啟壓力；尤其是高位消防水箱，若高位消防水箱的較低有效水位低于所選止回閥的較小開啟壓力，則有可能導(dǎo)致初期火災(zāi)滅火時止回閥無法打開，消火栓或噴頭無水可出，影響初期滅火。新疆止回閥需要多少錢</p><p
