不銹鋼止回閥介紹：不銹鋼止回閥屬自動閥類，又稱逆止閥、單向閥、回流閥或隔離閥等。根據(jù)閥瓣運動方式可分為旋啟式止回閥和升降式止回閥兩種。止回閥的作用是只允許介質(zhì)向一個方向流動，而且阻止反方向流動。在一個方向流動的流體壓力作用下，閥瓣打開，流體反方向流動時，由流體壓力和閥瓣的自重合閥瓣作用于閥座，從而切斷流動，以防止發(fā)生事故。不銹鋼止回閥廣泛應(yīng)用于各種泵的出口，防止介質(zhì)倒流對泵造成損壞，或安裝于高處，防止系統(tǒng)停機(jī)時，高壓水錘對管道及設(shè)備的破壞。旋啟式止回閥原理：旋啟式止回閥有一個斜置并能繞軸旋轉(zhuǎn)的閥瓣，介質(zhì)正向流動時，板打開，閥開啟，介質(zhì)倒流時，閥板壓住閥座關(guān)閉閥門。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)通道成流線型，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。臺臣牌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。升降式止回閥結(jié)構(gòu)原理：升降式止回閥工作時介質(zhì)從進(jìn)口端(下側(cè)）流入，從出口端（上側(cè)）流出。</p><p> 300X緩閉止回閥編輯鎖定緩閉止回閥是安裝在高層建筑給水系統(tǒng)以及其他給水系統(tǒng)的水泵出口處、防止介質(zhì)倒流、水錘及水擊現(xiàn)象的智能型閥門。該閥兼具電動閥、逆止閥和水錘消除器三種功能，可有效地提高供水系統(tǒng)的安全可靠性、并將緩開、速閉、緩閉消除水錘的技術(shù)原理一體化，防止開泵水錘和停泵水錘的產(chǎn)生。中文名300X緩閉止回閥應(yīng)用于高層建筑、生活區(qū)等實現(xiàn)啟閉，流量大、壓力損失小。組成主閥、單向閥、針閥目錄1結(jié)構(gòu)特點2工作原理300X緩閉止回閥結(jié)構(gòu)特點編輯300X緩閉止回閥由主閥、單向閥、針閥、球閥、微形過濾器和壓力表組成水力控制接管系統(tǒng)。利用水力自動操作，可使主閥得到比較好的開啟或關(guān)閉速度。防止水鍾水擊的產(chǎn)生，以達(dá)到緩閉消聲的效果。本產(chǎn)品利用水力自力控制，不需要其它裝置和能源，保養(yǎng)簡便，開啟及緩閉平穩(wěn)。本系列閥門產(chǎn)品范圍廣用于高層建筑、生活區(qū)等供水管網(wǎng)系統(tǒng)及城市供水工程。300X緩閉止回閥工作原理編輯當(dāng)閥門從進(jìn)口端給水時，水通過微型過濾器、針閥、單向閥進(jìn)入主閥控制室，再經(jīng)過球閥排水至下游。因為針閥開度小于球閥開度，即主閥控制室的排水速度大于進(jìn)水速度，因此控制室壓力降低，作用于主閥盤下端的進(jìn)口壓力打開主閥向下游供水。寧波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，對夾雙瓣旋啟式止回閥，液力止回閥。</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)停止流動或倒流時，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，閥瓣導(dǎo)向簡可在閥盞導(dǎo)向簡內(nèi)自由升降，當(dāng)介質(zhì)順流時，閥瓣靠介質(zhì)推力開啟，當(dāng)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。紹興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，對夾雙瓣旋啟式止回閥，液力止回閥。舟山多功能止回閥</p><p
