止回閥是指依靠介質(zhì)本身流動(dòng)而自動(dòng)開、閉閥瓣，用來防止介質(zhì)倒流的閥門，又稱逆止閥、單向閥、消聲止回閥逆流閥、和背壓閥。止回閥屬于一種自動(dòng)閥門，其主要作用是防止介質(zhì)倒流、防止泵及驅(qū)動(dòng)電動(dòng)機(jī)反轉(zhuǎn)，以及容器介質(zhì)的泄放。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(bǔ)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(dòng)）。止回閥的作用是只允許介質(zhì)向一個(gè)方向流動(dòng)，而且阻止方向流動(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，閥瓣打開；流體反方向流動(dòng)時(shí)，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(dòng)。不宜用于含有固體顆粒和粘度較大的介質(zhì)。</p><p style="text-indent:25px">止回閥前后介質(zhì)壓力處于接衡而又互相“拉鋸”的狀態(tài)，閥瓣經(jīng)常與閥座拍打，某些脆性材料（如鑄鐵、黃銅等）做成的閥瓣就被打碎。中國(guó)閥門產(chǎn)業(yè)鏈眾多，但非閥門強(qiáng)國(guó)?？傮w上去看我國(guó)已經(jīng)邁入了世界閥門大國(guó)的行列，但從產(chǎn)品質(zhì)量來看我國(guó)離閥門強(qiáng)國(guó)仍有很長(zhǎng)的一段差距。行業(yè)的生產(chǎn)集中度低、較好產(chǎn)品相配套的閥門研發(fā)能力低、閥門行業(yè)制造技術(shù)水平低等現(xiàn)象仍然存在，進(jìn)出口貿(mào)易逆差不斷擴(kuò)大。未來幾年將是閥門行業(yè)的高速震蕩期，這種高速震蕩帶來的直接后果是導(dǎo)致閥門櫥柜品牌陣營(yíng)中兩極分化的趨勢(shì)擴(kuò)大。預(yù)計(jì)今后幾年真正能夠在市場(chǎng)上存活的閥門企業(yè)不有這么多。但閥門行業(yè)的這種高速震蕩將帶來巨大的機(jī)會(huì)，震蕩的結(jié)果將會(huì)使市場(chǎng)運(yùn)作更加理性。止回閥只能安裝在水平管道上，在高壓小口徑止回閥上閥瓣可采用圓球。</p><div

style="text-indent:25px">由于上游的泵，彎頭或其他流量干擾，即使是尺寸合適的止回閥在處理湍流時(shí)也可能會(huì)不穩(wěn)定。優(yōu)良作法是在閥的上游留出一定長(zhǎng)度的直管，以使湍流消散（如果有空間的話）。通常，長(zhǎng)度為10D就足夠了。止回閥在保護(hù)流量系統(tǒng)中的其他組件方面起著重要作用。為了完成其工作，每個(gè)止回閥都必須是適合于應(yīng)用的類型，并且需要正確設(shè)置尺寸，以使其在正常工作流量下保持完全打開。正確選擇和選擇尺寸的止回閥可以具有較長(zhǎng)的無故障工作壽命。止回閥用于管路系統(tǒng)，作用是為了防止介質(zhì)倒流、防止泵及其啟動(dòng)電機(jī)反轉(zhuǎn)，以及容器內(nèi)介質(zhì)的泄放。止回閥還可用于給其中的壓力可能升至超過主系統(tǒng)壓力的輔助系統(tǒng)提供補(bǔ)給的管路上。止回閥安裝在管路上，即成為這一完整的流體部件之一，其閥瓣啟閉過程就要受它所處系統(tǒng)瞬變流動(dòng)狀態(tài)所影響；反之，閥瓣的關(guān)閉特性又對(duì)流體流動(dòng)狀態(tài)產(chǎn)生作用。閥門行業(yè)在國(guó)民經(jīng)濟(jì)發(fā)展中，作為準(zhǔn)備制造業(yè)的一個(gè)重要環(huán)節(jié)，起到非常重要的作用。新疆止回閥大概多少錢</p><p
