包括立管）上，也可用作放水閥和放氣閥。常見的關(guān)斷閥有閘閥、截止閥、球閥和蝶閥等。閘閥可分為明桿和暗桿、單閘板與雙閘板、楔形閘板與平行閘板等。閘閥關(guān)閉嚴(yán)密性不好，大直徑閘閥開啟困難；沿水流方向閥體尺寸小，流動阻力小，閘閥公稱直徑跨度大。截止閥按介質(zhì)流向分直通式、直角式和直流式三種，有明桿和暗桿之分。截止閥的關(guān)閉嚴(yán)密性較閘閥好，閥體長，流動阻力大，比較大公稱直徑為DN200。球閥的閥芯為開孔的圓球。板動閥桿使球體開孔正對管道軸線時為全開，轉(zhuǎn)90°為全閉。球閥有一定的調(diào)節(jié)性能，關(guān)閉較嚴(yán)密。蝶閥的閥芯為圓形閥板，它可沿垂直管道軸線的立軸轉(zhuǎn)動。當(dāng)閥板平面與管子軸線一致時，為全開；閘板平面與管子軸線垂直時，為全閉。蝶閥閥體長度小，流動阻力小，比閘閥和截止閥價格高。[1]（二）止回閥這類閥門用于防止介質(zhì)倒流，利用流體自身的動能自行開啟，反向流動時自動關(guān)閉。常設(shè)于水泵的出口、疏水器出口以及其他不允許流體反向流動的地方。止回閥分旋啟式、升降式和對夾式三種。對于旋啟式止回閥，流體只能從左向右流動時，反向流動時自動關(guān)閉。對于升降式止回閥，流體從左向右流動時，閥芯抬起，形成通路，反向流動時閥芯被壓緊到閥座上而被關(guān)閉。</p><div
