氣動(dòng)快開(kāi)排泥閥，是一種由液壓源或氣動(dòng)源作執(zhí)行機(jī)構(gòu)的角型截?cái)囝愰y門。通常成排安裝在沉淀池底部外側(cè)壁，用以排除池底沉淀的泥砂和污物。該閥由泥龍強(qiáng)化橡膠隔膜將閥門分為兩個(gè)腔室，接通液壓或氣動(dòng)源，采用電動(dòng)或手動(dòng)二位四通換向閥控制，實(shí)現(xiàn)快速排泥。該閥將隔膜代替活塞，無(wú)運(yùn)動(dòng)摩檫，更適用于泥漿等顆粒介質(zhì)，大大提高了閥門的使用壽命。

流體阻力小，其阻力系數(shù)與同長(zhǎng)度的管段相等。
2．結(jié)構(gòu)簡(jiǎn)單、體積小、重量輕。
3．緊密可靠，目前球閥的密封面材料廣泛使用塑料、密封性好，在真空系統(tǒng)中也已廣泛使用。
4．操作方便，開(kāi)閉迅速，從全開(kāi)到全關(guān)只要旋轉(zhuǎn)90°，便于遠(yuǎn)距離的控制。
5．維修方便，球閥結(jié)構(gòu)簡(jiǎn)單，密封圈一般都是活動(dòng)的，拆卸更換都比較方便。
6．在全開(kāi)或全閉時(shí)，球體和閥座的密封面與介質(zhì)隔離，介質(zhì)通過(guò)時(shí)，不會(huì)引起閥門密封面的侵蝕。
7．適用范圍廣，通徑從小到幾毫米，大到幾米，從高真空至高壓力都可應(yīng)用。
三片式鍛鋼球閥按其通道位置可分為直通式，三通式和直角式。后兩種球閥用于分配介質(zhì)與改變介質(zhì)的流向。三片式球閥安裝與維護(hù)應(yīng)注意以
