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(zhì)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(zhì)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(jié)構(gòu)分類3襯氟止回閥主要襯里4襯氟止回閥作用原理和結(jié)構(gòu)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(gòu)，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(gòu)，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。</p><p>

靜音止回閥是指依靠介質(zhì)本身流動而自動開、閉閥瓣，用來防止介質(zhì)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(zhì)倒流、防止泵及驅(qū)動電動機反轉(zhuǎn)，以及容器介質(zhì)的泄放。止回閥還可用于給其中的壓力可能升至超過系統(tǒng)壓的輔助系統(tǒng)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(zhuǎn)）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(qū)動電動機反轉(zhuǎn)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(shù)參數(shù)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(zhì)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(zhì)[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(gòu)，還有一個像門一樣的閥瓣自由地靠在傾斜的閥座表面上。麗水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。福州液力止回閥</p><p
