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(dòng)而不致倒流。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，西藏止回閥報(bào)價(jià)，止回閥只允許介質(zhì)向一個(gè)方向流動(dòng)的管路中使用，西藏止回閥報(bào)價(jià)，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，西藏止回閥報(bào)價(jià)、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(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)。西藏止回閥報(bào)價(jià)</p><div

style="text-indent:25px">止回閥，又稱單向閥、逆止閥，在石油化工行業(yè)中應(yīng)用非常普遍，在一些高風(fēng)險(xiǎn)裝置的關(guān)鍵部位如加氫裝置高壓離心泵出口、氫氣壓縮機(jī)出口、高壓系統(tǒng)和低壓系統(tǒng)界區(qū)都安裝止回閥。一些企業(yè)由于在設(shè)計(jì)、選材、使用、檢驗(yàn)、維修等環(huán)節(jié)管理不到位，導(dǎo)致止回閥失效，物料倒流，高壓系統(tǒng)物料向低壓系統(tǒng)反串，引起低壓設(shè)備損壞，或發(fā)生物料泄漏，引發(fā)火災(zāi)、事故。止回閥是存在運(yùn)動(dòng)部件的設(shè)備，存在損壞可能，必須對(duì)止回閥定期進(jìn)行檢驗(yàn)和修理，才能確保其可靠性。一些關(guān)鍵部位的止回閥的重要性不低于安全閥，目前國家標(biāo)準(zhǔn)、企業(yè)的管理制度中對(duì)安全閥的檢查和校驗(yàn)都有明確要求，但是沒有對(duì)止回閥進(jìn)行定期檢驗(yàn)、維修的制度、規(guī)定、標(biāo)準(zhǔn)。止回閥不在國家強(qiáng)制檢驗(yàn)范圍之內(nèi)，只是列入一般閥門管理。西藏止回閥報(bào)價(jià)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。</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度的直管，以使湍流消散（如果有空間的話）。通常，長度為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。 </p><p style="text-indent:25px"> 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。對(duì)于要求關(guān)閉時(shí)水擊沖擊比較小或無水擊的管路，宜選用緩閉式旋啟止回閥和緩閉式蝶形止回閥。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">止回閥的選型標(biāo)準(zhǔn)內(nèi)容如下： 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(duì)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。止回閥屬自動(dòng)閥類，又稱逆止閥、單向閥、回流閥或隔離閥。西藏止回閥特點(diǎn)</p><p style="text-indent:25px">由于止回閥啟閉動(dòng)作較為頻繁，內(nèi)部連接部分及密封部件容易發(fā)生損壞。西藏止回閥報(bào)價(jià)</p><p 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(duì)于母管制水泵系統(tǒng)，防止發(fā)生倒流的情況。西藏止回閥報(bào)價(jià)</p><p
