style="text-indent:25px">旋啟式止回閥的閥瓣繞轉(zhuǎn)軸作旋轉(zhuǎn)運動。其流體阻力一般小于升降式止回閥，它適用于較大口徑的場合。旋啟式止回閥根據(jù)閥瓣的數(shù)目可分為單瓣旋啟式、雙瓣旋啟式及多瓣旋啟式三種。單瓣旋啟式止回閥一般適用于中等口徑的場合。大口徑管路選用單瓣旋啟式止回閥時，為減少水錘壓力，比較好的是采用能減小水錘壓力的緩閉止回閥。雙瓣旋啟式止回閥適用于大中口徑管路。對夾雙瓣旋啟式止回閥結(jié)構(gòu)小、重量輕，是一種發(fā)展較快的止回閥;多瓣旋啟式止回閥適用于大口徑管路。</p><p style="text-indent:25px">止回閥的工作特點是載荷變化大，啟閉頻率小，一投入關(guān)閉或開啟狀態(tài)，適用周期便很長，且不要求運動部件運動。但一旦又“切換”要求，則必須動之靈活，這一要求較常見的機械運動更為苛刻。由于止回閥在大多數(shù)實際使用中，定性地確定用于快速關(guān)閉，而在止回閥關(guān)閉的瞬間，介質(zhì)是方向流動的，隨著閥瓣的關(guān)閉，介質(zhì)從大的倒流速度迅速降至零，而壓力則迅速升高，即產(chǎn)生可能對管路系統(tǒng)有破壞作用的“水錘”現(xiàn)象。對于多臺泵并聯(lián)適用的高壓管路系統(tǒng)，止回閥的水錘問題更加突出。水錘是壓力管道中瞬變流動中的一種壓力波，它是由于壓力管道中流體流速的變化而引起的壓力升躍或下降的水力沖擊現(xiàn)象。其產(chǎn)生的物理原因是流體的不可壓縮性、流體運動慣性與管道彈性的綜合作用結(jié)果。為了防止管道中的水錘隱患，多年來，人們在止回閥的設(shè)計中，采用了一些新結(jié)構(gòu)、新材料，在保證止回閥適用性能的同時，將水錘的沖擊力減至小方面取得了可喜的進(jìn)展。國標(biāo)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、和背壓閥。</p><div
