由于該類閥門的閥桿開啟或關(guān)閉行程相對(duì)較短，而且具有非?？煽康那袛喙δ埽钟捎陂y座通口的變化與閥瓣的行程成正比例關(guān)系，非常適合于對(duì)流量的調(diào)節(jié)。因此，這種類型的閥門非常適合作為切斷或調(diào)節(jié)以及節(jié)流使用。截止閥的選用原則是：1、高溫、高壓介質(zhì)的管路或裝置上宜選用截止閥。如火電廠、核電站，石油化工系統(tǒng)的高溫、高壓管路上。2、管路上對(duì)流阻要求不嚴(yán)的管路上，紹興對(duì)夾蝶形止回閥。即對(duì)壓力損失考慮不大的地方。3、小型閥門可選用針閥、儀表閥、取樣閥、壓力計(jì)閥等。4、有流量調(diào)節(jié)或壓力調(diào)節(jié)，但對(duì)調(diào)節(jié)精度要求不高，而且管路直徑又比較小，如公稱通經(jīng)≤50mm的管路上，宜選用。5、合成工業(yè)生產(chǎn)中的小化肥和大化肥宜選用公稱壓力PN160公稱壓力16MPa或PN320公稱壓力32MPa的高壓角式截止閥或高壓角式節(jié)流閥。6、氧化鋁拜耳法生產(chǎn)中的脫硅車間、易結(jié)焦的管路上，易選用閥體分開式、閥座可去處的、硬質(zhì)合金密封副的直流式截止閥或直流式節(jié)流閥。7、城市建設(shè)中的供水、供熱工程上，公稱通經(jīng)較小的管路，紹興對(duì)夾蝶形止回閥，可選用截止、平衡閥或柱塞閥，如公稱通經(jīng)小于150mm的管路上。優(yōu)明顯的優(yōu)點(diǎn)是：在開啟和關(guān)閉過程中，由于閥瓣于閥體密封面間的摩擦力比閘閥小，因而耐磨，紹興對(duì)夾蝶形止回閥。衢州鼎力閥門是一家專門生產(chǎn)制造銷售止回閥的公司，主要有通風(fēng)止回閥，對(duì)夾雙瓣旋啟式止回閥，液力止回閥。紹興對(duì)夾蝶形止回閥</p><div

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。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。管道式止回閥是新出現(xiàn)的一種閥門，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：這種閥門是做為鍋爐給水和蒸汽切斷用閥。蚌埠防火止回閥臺(tái)州鼎力閥門是一家專門生產(chǎn)制造銷售止回閥的公司，主要有靜音止回閥，對(duì)夾蝶形止回閥，消聲止回閥。</p><div
