流體壓力使閥瓣從閥座密封面上抬起，介質回流導致閥瓣回落到閥座上，并切斷流動。根據使用條件，閥瓣可以是全金屬結構，也可以是在閥瓣架上鑲嵌橡膠墊或橡膠環(huán)的形式。像截止閥一樣，流體通過升降式止回閥的通道也是狹窄的，因此通過升降式止回閥的壓力降比旋啟式止回閥大些，而且旋啟式止回閥的流量受到的限制很少[1]。襯氟止回閥襯氟止回閥結構分類編輯1、襯氟止回閥的閥瓣呈圓盤狀，繞閥座通道的轉軸作旋轉運動，因閥內通道成流線型，流動阻力比升蝶式止回閥小，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。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停止流動或倒流時，減弱水力沖擊。2、襯氟止回閥：閥瓣沿著閥體垂直中心線滑動的止回閥，消聲止回閥只能安裝在水平管道上優(yōu)好安裝在垂直管道上，在高壓小口徑止回閥上閥瓣可采用圓球。消聲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較大。其結構與截止閥相似，閥體和閥瓣與截止閥相同。閥瓣上部和閥蓋下部加工有導向套簡，閥瓣導向簡可在閥盞導向簡內自由升降，當介質順流時，閥瓣靠介質推力開啟。</p><p> 截止止回閥（stop-checkvalve）兼有截止閥和止回閥功能的多用閥門。它的結構形式與截止閥相似，但閥桿與閥瓣不是固定聯接。當閥桿下降將閥瓣緊壓在閥座上時，起截止閥作用；閥桿上升后，則起止回閥作用。在同時需要安裝截止閥(或閘閥)和止回閥的管道上（如水泵的出口端），或在安裝位置受到限制的場所（如船舶），使用截止止回閥可節(jié)約安裝費用和空間位置。中文名截止止回閥外文名stop-checkvalve性質多用閥門功能兼有截止閥和止回閥功能目錄1結構特點2標準與規(guī)范3選用要求截止止回閥結構特點編輯截止的閥瓣、閥座密封面堆焊鐵基合金或司太立鈷基硬質合金，具有耐磨、耐截止止回閥高溫、耐腐蝕、抗擦傷性能好、使用壽命長的特點。截止止回多用閥（多功能止回閥）產品可適用于石油、化工、制藥、電力行業(yè)等各種工況的水平安裝管路上。截止止回閥標準與規(guī)范編輯設計與制造：GB12235結構長度：GB12221壓力-溫度等級：GB9131、JB/T74、HG20604連接法蘭：JB/T79、GB9113、HG20592試驗與檢驗：JB/T9092、GB13927截止止回閥選用要求編輯截止閥是指關閉件(閥瓣)沿閥座中心線移動的閥門。根據閥瓣的這種移動形式，閥座通口的變化是與閥瓣行程成正比例關系。衢州鼎力閥門是一家專門生產制造銷售止回閥的公司，主要有通風止回閥，對夾雙瓣旋啟式止回閥，液力止回閥。</p><div

靜音止回閥是指依靠介質本身流動而自動開、閉閥瓣，用來防止介質倒流的閥門，又稱逆止閥、單向閥、逆流閥、和背壓閥。止回閥屬于一種自動閥門，其主要作用是防止介質倒流、防止泵及驅動電動機反轉，以及容器介質的泄放。止回閥還可用于給其中的壓力可能升至超過系統壓的輔助系統提供補給的管路上。止回閥主要可分為旋啟式止回閥（依重心旋轉）與升降式止回閥（沿軸線移動）。中文名靜音止回閥外文名Silentcheckvalve別稱逆止閥、單向閥、逆流閥和背壓閥作用防止泵及驅動電動機反轉歸類一種自動閥門分類旋啟式止回閥與升降式止回閥目錄1作用2類型3分類4用途5工作原理6零件材料7安裝和使用8組成9主要技術參數10外形尺寸靜音止回閥作用編輯止回閥的作用是只允許介質向一個方向流動，而且阻止反方向流動。通常這種閥門是自動工作的，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。不宜用于含有固體顆粒和粘度較大的介質[1]。靜音止回閥類型編輯它包括旋啟式止回閥和升降式止回閥。旋啟式止回閥有一個鉸鏈機構，還有一個像門一樣的閥瓣自由地靠在傾斜的閥座表面上。溫州鼎力閥門是一家專門生產制造銷售止回閥的公司，主要有靜音止回閥，對夾蝶形止回閥，消聲止回閥。蕪湖通風止回閥</p><p
