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。福建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
