止回閥的分類止回閥根據(jù)其結(jié)構(gòu)和安裝方式可分：一、旋啟式止回閥：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)運動，因閥內(nèi)通道成流線形，流動阻力比升降式止回閥小，適用于低流速和流動不常變化的大口徑場合，但不宜用于脈動流，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)停止流動或倒流時，減弱水力沖擊。二、升降式止回閥：閥瓣沿著閥體垂直中心線滑動的止回閥，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。其結(jié)構(gòu)與截止閥相似，閥體和閥瓣與截止閥相同。閥瓣上部和閥蓋下部加工有導向套簡，閥瓣導向簡可在閥盞導向簡內(nèi)自由升降，當介質(zhì)順流時，閥瓣靠介質(zhì)推力開啟，當介質(zhì)停流時，閥瓣靠自垂降落在閥座上，起阻止介質(zhì)逆流作用。直通式升降止回閥介質(zhì)進出口通道方向與閥座通道方向垂直；立式升降式止回閥，其介質(zhì)進出口通道方向與閥座通道方向相同，其流動阻力較直通式小。三、碟式止回閥：閥瓣圍繞閥座內(nèi)的銷軸旋轉(zhuǎn)的止回閥。碟式止回閥結(jié)構(gòu)簡單。江西鼎力閥門是一家專門生產(chǎn)制造銷售止回閥的公司，主要有靜微阻球形止回閥，滑道滾求式止回閥等。</p><div

球形止回閥以其密封性好、流阻極小等性能優(yōu)勢，得到了范圍廣的應用和推廣，其結(jié)構(gòu)從優(yōu)初的“單球式”止回閥逐步完善到“獨自多流道多球式”止回閥。止回閥是流體傳輸優(yōu)常用的設備種類之一，現(xiàn)有的止回閥存在阻力大、能耗大的問題。降低流阻系數(shù)是流體傳輸節(jié)能的重要途徑。常見的止回閥包括球形止回閥、對夾式止回閥等。這些止回閥的共同缺點是：在流體正向流動、止回閥打開時，止回閥的某些零部件例如閥瓣或球體等處于流道的**，存在一定的擋水面積，對流體的流動阻力較大，使出水壓力有所降低，因此浪費能量。球形止回閥結(jié)構(gòu)和工作原理編輯球形止回閥是一種采用多球、多流道、多錐型倒流體結(jié)構(gòu)的止回閥，主要由前后閥體、膠球、錐型體等組成。其工作原理是：膠球在球罩內(nèi)作短行程滾動來實現(xiàn)閥門的啟閉。當水泵開動時，水在壓力的作用下沖開膠球，使膠球滾至右側(cè)，由后閥體中的錐形體固定其位置，止回閥開啟；泵停后，由于管路系統(tǒng)中的回水壓力，迫使膠球滾至左側(cè)前閥體，達到止回閻的關(guān)閉。膠球采用空心鋼球，外附彈性很好的橡膠既保證密封，又能保證減小關(guān)閥過程中對管道系統(tǒng)的破壞。帶孔的錐型體在閥門打開時對鋼球起固定作用和消除膠球與錐型體接觸面積的壓強。臺州耐腐蝕緩沖止回閥</p><p
