離心泵出口的止回閥的作用就是防止出口管路中的液體倒流形成水錘造成泵內(nèi)葉輪損傷。止回閥的安裝與泵的多少無(wú)關(guān),止回閥主要為了在泵停止運(yùn)行后，防止液體回流，使泵倒轉(zhuǎn),從而造成損壞泵的事故。泵出口止回閥的安裝： 1、旋啟式止回閥一般安裝在水平管道上：對(duì)于口徑DN<80mm的止回閥，也可安裝在垂直或向上傾斜的管道上。 2、直通式升降式止回閥應(yīng)安裝在水平管道上;立式升降式止回閥必須安裝在垂直管道上，介質(zhì)為自下而上流動(dòng)。 3、由于止回閥容易損壞，因此，應(yīng)靠近泵出口安裝止回閥，在止回閥上部設(shè)有切斷閥(一般用球閥或閘閥)，方便檢修。 4、為便于止回閥拆卸前泄壓，對(duì)于止回閥本身不帶放凈閥的，應(yīng)在止回閥與切斷閥之間加裝泄壓用放凈閥。</p><p style="text-indent:25px">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(dòng)作來(lái)阻斷介質(zhì)倒流的一種閥門(mén)。屬自動(dòng)閥類(lèi)，又稱(chēng)逆止閥、單向閥、回流閥或隔離閥。閥瓣運(yùn)動(dòng)方式分為升降式和旋啟式。升降式止回閥與截止閥結(jié)構(gòu)類(lèi)似，僅缺少帶動(dòng)閥瓣的閥桿。介質(zhì)從進(jìn)口端(下側(cè))流入，從出口端(上側(cè))流出。當(dāng)進(jìn)口壓力大于閥瓣重量及其流動(dòng)阻力之和時(shí)，閥門(mén)被開(kāi)啟。反之，介質(zhì)倒流時(shí)閥門(mén)則關(guān)閉。旋啟式止回閥有一個(gè)斜置并能繞軸旋轉(zhuǎn)的閥瓣，工作原理與升降式止回閥相似。止回閥常用作抽水裝置的底閥，可以阻止水的回流。止回閥與截止閥組合使用，可起到安全隔離的作用。缺點(diǎn)是阻力大，關(guān)閉時(shí)密封性差。止回閥的設(shè)置，起到了防止物料倒流，避免泵葉輪遭受液擊的作用。</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(huà)）。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(lèi)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(kāi)。正確選擇和選擇尺寸的止回閥可以具有較長(zhǎng)的無(wú)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(guò)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(guò)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。廣西止回閥質(zhì)量</p><p
