</p><p> <span style="font-size:16px;">雙閥瓣止回閥設(shè)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(shè)計是從閥體一端軸向地安裝所有內(nèi)件，內(nèi)部止動件固定鏈銷而不必穿透閥體。套筒式閥將所有的內(nèi)部組件，包括閥座，安裝在閥體內(nèi)的軸向鎖定的一個套筒內(nèi)。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(fù)。套筒可以在工作臺上維修和檢查而非現(xiàn)場。所有的設(shè)計應(yīng)包括一個固定的彈簧擋板，使每個閥辦能夠獨立地彈開和平衡且同步運(yùn)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(dá)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(dá)到DN2100和閥門的壓力等級比較高可達(dá)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(chǎn)的口徑為DN15?DN100。比較大的壓力是lOObar?，溫度可達(dá)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;">止回閥，顧名思義，在系統(tǒng)中阻止流體反向流動，是壓縮機(jī)和泵系統(tǒng)常用的閥門。P&IDs顯示了工程師是如何連接設(shè)備和儀器的。不同的壓縮機(jī)和泵有不同的符號，這可以讓設(shè)計師決定選用什么元件。P&IDs不顯示管道的位置，為了適應(yīng)具體安裝，各種設(shè)備元件有多種考裝方式。根據(jù)止回閥類型，管道的運(yùn)行位置、走向必須提前決定。渦輪機(jī)不總是與止回閥連接。當(dāng)渦輪機(jī)產(chǎn)生的全部壓力作為管道摩擦損失而消耗時，具有單個渦輪機(jī)的系統(tǒng)不要求使用止回閥，因為沒有介質(zhì)倒流的可能。這種情況在現(xiàn)實中很少發(fā)生，因為大部分的管道系統(tǒng)中都有一個高度差的變化，要求渦輪機(jī)將穩(wěn)定的水頭傳遞給帶系統(tǒng)壓力的流體。當(dāng)機(jī)器停止時，液體就會回流到系統(tǒng)的比較低點，靜水頭消失。止回閥可以阻止液體回流到抽水泵。</span>
