當進口壓力大于閥瓣重量及出口壓力時，閥門開啟；反之，介質倒流時由出口壓力及閥瓣的重量壓住閥座，閥門關閉。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壓力產(chǎn)生動作來阻斷介質倒流的一種自動閥，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，當介質停流時，閥瓣靠自垂降落在閥座上，起阻止介質逆流作用。對夾式蝶形止回閥用途：對夾式蝶形止回閥閥瓣圍繞閥座內的銷軸旋轉的止回閥。當介質按規(guī)定方向流動時，閥瓣受介質力的作用，被開啟，介質逆流時，因閥瓣自重和閥瓣受介質反向力的作用，使閥瓣與閥座的密封面密合而關閉，達到阻止介質逆流的目的。對夾式蝶形止回閥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。</p><p> 襯氟止回閥又稱逆止閥。這種類型的閥門的作用是只允許介質向一個方向流動，而且阻止方向流動。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。中文名襯氟止回閥外文名Fluorine-linedcheckvalve又稱逆止閥作用只允許介質向一個方向流動工作自動工作目錄1簡介2襯氟止回閥結構分類3襯氟止回閥主要襯里4襯氟止回閥作用原理和結構5性能參數(shù)6襯氟止回閥主要零部件材料襯氟止回閥簡介編輯襯氟止回閥包括旋啟式止回閥和升降式止回閥。旋啟式止回閥有一介鉸鏈機構，還有一個像門一樣的閥瓣自由地靠在傾斜的閥座表面上。為了確保閥瓣每次都能到達閥座面的合適位置，閥瓣設計在鉸鏈機構，以便閥瓣具有足夠有旋啟空間，并使閥瓣真正的、范圍廣的與閥座接觸。閥瓣可以全部用金屬制成，也可以在金屬上鑲嵌皮革、橡膠、或者采用合成覆蓋面，這取決于使用性能的要求。旋啟式止回閥在完全打開的狀況***體壓力幾乎不受阻礙，因此通過閥門的壓力降相對較小。升降式止回閥的閥瓣座落位于閥體上閥座密封面上。此閥門除了閥瓣可以自由地升降之外，其余部分如同截止閥一樣。寧波鼎力閥門是一家專門生產(chǎn)制造銷售止回閥的公司，主要有靜音止回閥，對夾蝶形止回閥，消聲止回閥。</p><div

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。[2]止回閥分類編輯啟閉件靠介質流動的力量自行開啟或關閉，以防止介質倒流的閥門叫止回閥。止回閥屬于自動閥類，主要用于介質單向流動的管道上，只允許介質向一個方向流動，以防止發(fā)生事故。止回閥結構分類按結構劃分，可分為升降式止回閥、旋啟式止回閥和蝶式止回閥三種：1.升降式止回閥分為立式和臥式兩種。2.旋啟式止回閥分為單瓣式、雙瓣式和多瓣式三種。3.蝶式止回閥為直通式。以上幾種止回閥在連接形式上可分為螺紋連接、法蘭連接、焊接連接和對夾連接四種。止回閥材質分類1.鑄鐵止回閥2.黃銅止回閥3.不銹鋼止回閥4.碳鋼止回閥5.鍛鋼止回閥止回閥功能分類靜音式止回閥不銹鋼止回閥靜音式止回閥靜音式止回閥止回閥安裝編輯止回閥安裝方法一、旋啟式止回閥：旋啟式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。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停止流動或倒流時。義烏鼎力閥門是一家專門生產(chǎn)制造銷售止回閥的公司，主要有靜微阻球形止回閥，滑道滾求式止回閥等。日照滑道滾求式止回閥</p><p
