style="font-size:16px;">雙閥瓣止回閥設計特征傳統(tǒng)的做法是配置鉸鏈銷通過閥體并且由螺紋塞或法蘭來提供壓力密封。非固定式設計是從閥體一端軸向地安裝所有內件，內部止動件固定鏈銷而不必穿透閥體。套筒式閥將所有的內部組件，包括閥座，安裝在閥體內的軸向鎖定的一個套筒內。同樣，閥體也不必被穿透而存在潛在泄漏的路徑。備件套筒可以儲存以便在緊急情況下快速修復。套筒可以在工作臺上維修和檢查而非現(xiàn)場。所有的設計應包括一個固定的彈簧擋板，使每個閥辦能夠**地彈開和平衡且同步運行。通常，閥具有鑄鋼的閥體和套筒和11/13Cr的閥瓣。閥座可以是一體的和硬面的或有軟密封的。閥門口徑為DN50?DN600,壓力可以達到壓力ANSI150LB?1500LB;閥門口徑小于DN300的，壓力可以做到2500LB。閥門的口徑達到DN2100和閥門的壓力等級比較高可達到ANSI4500LB的也適用。某些金屬對夾止回閥有一個襯里。有PFA襯里的不銹鋼閥門被大規(guī)模生產的口徑為DN15?DN100。比較大的壓力是lOObar?，溫度可達200℃。鑄鐵對夾閥門，帶有鋁青銅的閥瓣，口徑可從DN50到DN600;壓力為16bar。閥體可用環(huán)氧樹脂來防止腐蝕。</span>

style="font-size:16px;">消聲止回閥主要適用于高層建筑供水、排水系統(tǒng)，消防管道給水系統(tǒng)等。此消聲止回閥可有效地防止介質倒流而產生破壞性水錘，保護水泵和管道其它設備。1、閥瓣采用頭”外形設計，閥體采用“腰鼓”外形設計，改善介質流向，降低流阻系數(shù)。2、閥門采用短結構形式，雖然水頭損失比升降式靜音止回閥稍大些，但體積小、價格便宜。3、結構緊湊，導向軸與導向架之間裝有非金屬潤滑套，閥瓣升降靈活，不會產生抱死現(xiàn)象。4、骨架式橡膠密封圈直接鑲嵌在閥體上，避免了介質長時間對密封圈的直接沖刷，使用壽命明顯延長，堅固、耐用。5、閥瓣啟閉行程短，可以有效的防止水錘產生。6、適用于給排水系統(tǒng)，高層建筑管網，可安裝在泵的出口處，結構稍加改動，可做為吸水底閥使用，但不適用于污水管網。</span> </p><p> <span style="font-size:16px;">倒流防止器的原理作用：防止水倒流.但無防污性能,當止回密封面失效，不能有效防止水的回流污染。設有倒流防止器的管段,不需要再設止回閥；反之不能替代。1、正向通水進口壓力大于出口壓力時，兩個止回閥瓣開啟，排水器關閉。在2m/s流速時，流通水損小于。2、反向關閉進口壓力小于等于出口壓力時，兩個止回閥瓣關閉，排水器開啟。如果沒有垃圾卡阻，兩個止回閥瓣密封關閉，排水器出口不排水，中間腔與大氣相通，中間腔壓力為零。3、防止回流污染進口壓力小于出口壓力時，兩個止回閥瓣處于關閉狀態(tài)，排水器處于開啟狀態(tài)如果其中一個或兩個止回閥瓣的閥口有垃圾卡阻，產生滲漏，所漏介質均流向中間腔，經過排水器直接排出閥外，防止對進口端的回流污染。</span>

style="font-size:16px;">止回閥按結構劃分，可分為升降式止回閥、旋啟式止回閥和蝶式止回閥三種。升降式止回閥可分為立式和直通式兩種。旋啟式止回閥分為單瓣式、雙瓣式和多瓣式三種。蝶式止回閥分為蝶式雙瓣、蝶式單瓣，以上幾種止回閥在連接形式上可分為螺紋連接、法蘭連接、焊接和對夾式連接四種。安裝止回閥是為了保證水泵內部水流的流向，從而保障水泵的正常工作。所以關于止回閥的安裝位置，到底是安裝在水泵前還是水泵后，可以分兩種情況：一種是安裝在水泵前豎吸管端頭，也叫底閥。目的是為了不用抽一次水向水泵充一次水，因為水泵內以及泵前的吸管內無水時水泵只能空轉抽不上水，所以水泵內必須充滿水才能抽出水。這種水泵的安裝是高于液面時的一種方法，也叫負壓法。</span>
