style="text-indent:25px">不銹鋼止回閥又稱為逆流閥、逆止閥、背壓閥、單向閥。這類閥門是靠管路中介質(zhì)本身的流動(dòng)產(chǎn)生的力而自動(dòng)開啟和關(guān)閉的，屬于一種自動(dòng)閥門。不銹鋼止回閥分為升降式不銹鋼止回閥，旋啟式不銹鋼止回閥，圓盤式不銹鋼止回閥。不銹鋼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。不銹鋼止回閥根據(jù)材質(zhì)的不同，可以適用于各種介質(zhì)的管路上。止回閥安裝在管路上，即成為這一完整管路的流體部件之一，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；反過來，閥瓣的關(guān)閉特性又對(duì)流體流動(dòng)狀態(tài)產(chǎn)生作用。美標(biāo)止回閥的閥瓣為旋啟式，流道為直通式，水平管道、垂直管道均可安裝。</p><div

style="text-indent:25px">旋啟式止回閥安裝方法：旋啟式止回閥的閥瓣呈圓盤狀，繞閥座通道的轉(zhuǎn)軸作旋轉(zhuǎn)運(yùn)動(dòng)，因閥內(nèi)通道成流線型，流動(dòng)阻力比升降式止回閥小，適用于低流速和流動(dòng)不常變化的大口徑場(chǎng)合，但不宜用于脈動(dòng)流，其密封性能不及升降式。旋啟式止回閥分單瓣式、雙瓣式和多半式三種，這三種形式主要按閥門口徑來分，目的是為了防止介質(zhì)停止流動(dòng)或倒流時(shí)，減弱水力沖擊。升降式止回閥：閥瓣沿著閥體垂直中心線滑動(dòng)的止回閥，升降式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。升降式止回閥的閥體形狀與截止閥一樣（可與截止閥通用），因此它的流體阻力系數(shù)較大。升降式止回閥的結(jié)構(gòu)一般與截止閥相似，其閥瓣沿著通道中以線作升降運(yùn)動(dòng)，動(dòng)作可靠。遼寧ＷＣ９美標(biāo)電站止回閥生產(chǎn)廠家</p><p
