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。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)的止同閥，主要由前后閥體、膠球、錐型體等組成。中文名球形止回閥外文名Sphericalcheckvalve閥瓣橡膠包皮球公稱壓力：～公稱經(jīng)：40～350mm目錄1止回閥概述2結(jié)構(gòu)和工作原理3多流道球形止回閥?結(jié)構(gòu)?概述4節(jié)能設(shè)計(jì)?結(jié)構(gòu)和原理?優(yōu)點(diǎn)球形止回閥止回閥概述編輯止回閥是用于管路系統(tǒng)介質(zhì)順流時(shí)開啟、逆流時(shí)關(guān)閉的自動(dòng)閥門，主要作用是防止介質(zhì)的倒流、泵及驅(qū)動(dòng)機(jī)球形止回閥械反轉(zhuǎn)，防止水泵及驅(qū)動(dòng)電機(jī)突然停止運(yùn)行時(shí)產(chǎn)生的水擊波，減輕對(duì)管路系統(tǒng)的破壞。止回閥按關(guān)閉件與閥座的相對(duì)位移方式可以分為：升降式、旋啟式、碟形、隔膜式和球形止回閥等五大類。對(duì)于上述止回閥，大多存在以下缺點(diǎn)：關(guān)閉時(shí)由于水錘作用產(chǎn)生的“巨響”和振動(dòng)；由于閥板振動(dòng)使閥中“關(guān)節(jié)性零件”軸和軸套之間產(chǎn)生機(jī)械摩擦運(yùn)動(dòng)，當(dāng)閥板振動(dòng)頻率過高時(shí)，軸和軸套間會(huì)產(chǎn)生機(jī)械摩擦運(yùn)動(dòng)，閥板移位，密封失效，有時(shí)會(huì)造成閥板脫落，使系統(tǒng)保護(hù)失效；閥內(nèi)流體流態(tài)紊亂，流阻損失大，能源損失嚴(yán)重等。為避免和改善以上缺點(diǎn)。</p><p> 當(dāng)進(jìn)口壓力大于閥瓣重量及出口壓力時(shí)，閥門開啟；反之，介質(zhì)倒流時(shí)由出口壓力及閥瓣的重量壓住閥座，閥門關(guān)閉。升降式止回閥只能安裝在水平管道上，該閥啟閉件為圓形閥瓣，并靠自身重量及介質(zhì)壓力產(chǎn)生動(dòng)作來阻斷介質(zhì)倒流的一種自動(dòng)閥，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。對(duì)夾式蝶形止回閥用途：對(duì)夾式蝶形止回閥閥瓣圍繞閥座內(nèi)的銷軸旋轉(zhuǎn)的止回閥。當(dāng)介質(zhì)按規(guī)定方向流動(dòng)時(shí)，閥瓣受介質(zhì)力的作用，被開啟，介質(zhì)逆流時(shí)，因閥瓣自重和閥瓣受介質(zhì)反向力的作用，使閥瓣與閥座的密封面密合而關(guān)閉，達(dá)到阻止介質(zhì)逆流的目的。對(duì)夾式蝶形止回閥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。浙江鼎力閥門是一家專門生產(chǎn)制造銷售止回閥的公司，主要有雙瓣旋啟式止回閥，耐腐蝕緩沖止回閥等。</p><div

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?，又由于閥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。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，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。龍巖耐腐蝕緩沖止回閥</p><p
