style="font-size:16px;">止回閥的啟閉是依靠介質(zhì)流動力量自行開啟和關(guān)閉。止回閥屬于自動閥產(chǎn)品，止回閥只允許介質(zhì)向一個方向流動的管路中使用，防止介質(zhì)回流的現(xiàn)象發(fā)生。其使用范圍***，可適用大小口徑、各種介質(zhì)、電站高壓系統(tǒng)中使用。止回閥開啟是指依靠介質(zhì)正向流動打開閥瓣，同樣的道理介質(zhì)倒流推動閥瓣而關(guān)閉，止回閥還稱之為逆止閥、單向閥、逆流閥和背壓閥。多屬于自動閥門，主要功能是用來防止介質(zhì)倒流，防止泵及驅(qū)動電機反轉(zhuǎn)和容器介質(zhì)的泄放使用。同時還用于壓力可能升至超過系統(tǒng)壓的輔助系統(tǒng)中作安全保護。止回閥主要是用來防止管道中的介質(zhì)倒流使用。底閥及鴨嘴閥也是屬于止回閥系類。止回閥可分為升降式、旋啟式、碟型三種：⑴升降式又分為立式和臥式2種，升降式結(jié)構(gòu)是沿軸線移動。實例：①升降式靜音止回閥是用在給排水工程質(zhì)量要求高的管線上；同時可安裝在泵的出口處，要求壓力（）相對高的管網(wǎng)，是防水沖擊止回閥的重要產(chǎn)品。②升降式消聲止回閥適用于高層</span><span

style="font-size:16px;">止回閥啟閉動作較為頻繁，內(nèi)部連接部分及密封部件容易發(fā)生損壞，為便于修理，防止發(fā)生由于止回閥故障而停運整個系統(tǒng)的情況，從這個角度考慮，止回閥會裝在出口閘閥或蝶閥之前，止回閥有多種樣式，它們使用不同的機制來阻止倒流，包括盤，球，活塞和其他形式。流量可以是直通，成角度或舉升形式。每種類型的止回閥都有其優(yōu)勢。旋啟式止回閥可允許使用通過管道的清管器清潔或檢查管道。其他人在垂直流方面表現(xiàn)比較好。有些可以在線維修。某些含有固體或纖維材料的可耐受流動。配件可以微調(diào)閥門的性能。杠桿和配重，彈簧，氣墊或減震器的各種組合可幫助控制閥門的關(guān)閉速度以匹配應(yīng)用，并防止閥門猛擊和水錘問題。其他附件，例如位置指示器，提供操作信息。Bregman說，在許多應(yīng)用中，比較好包括一個</span><span
