蝶式止回閥分單瓣式、雙瓣式和多半式三種，這三種形式主要按閥門(mén)口徑來(lái)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。2、靜音止回閥：閥瓣沿著閥體垂直中心線滑動(dòng)的止回閥，內(nèi)螺紋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。蝶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(dǎo)向套簡(jiǎn)，閥瓣導(dǎo)向簡(jiǎn)可在閥盞導(dǎo)向簡(jiǎn)內(nèi)自由升降，當(dāng)介質(zhì)順流時(shí)，閥瓣靠介質(zhì)推力開(kāi)啟，當(dāng)介質(zhì)停流時(shí)，閥瓣靠自垂降落在閥座上，起阻止介質(zhì)逆流作用。直通式蝶式止回閥介質(zhì)進(jìn)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(jìn)出口通道方向與閥座通道方向相同，其流動(dòng)阻力較直通式小。3、靜音止回閥：閥瓣圍繞閥座內(nèi)的銷(xiāo)軸旋轉(zhuǎn)的止回閥。碟式止回閥結(jié)構(gòu)簡(jiǎn)單，只能安裝在水平管道上，密封性較好。4、靜音止回閥：閥瓣沿著閥體中心線滑動(dòng)的閥門(mén)。管道式止回閥是新出現(xiàn)的一種閥門(mén)，它的體積小，重量較輕，加工工藝性好，是止回閥發(fā)展方向之一。但流體阻力系數(shù)比旋啟式止回閥略大。5、壓緊式止回閥：這種閥門(mén)是做為鍋爐給水和蒸汽切斷用閥。寧德HC41W消聲止回閥山西鼎力閥門(mén)是一家專(zhuān)門(mén)生產(chǎn)制造銷(xiāo)售止回閥的公司，主要有雙瓣旋啟式止回閥，耐腐蝕緩沖止回閥等。</p><div
