style="font-size:16px;">偏心旋轉(zhuǎn)半球閥閥體流路簡單，阻力小，與同口徑單、雙座閥相比，有較大的流通能力，但重量只有其1/3左右。偏轉(zhuǎn)閥采用旋轉(zhuǎn)運動，提高了填料函密封性，同時具有較大的輸出力，所以閥的泄漏較小，剛度較大，在額定壓差下能可靠地工作。偏心旋轉(zhuǎn)閥芯、閥桿只作旋轉(zhuǎn)運動，所以它開關(guān)轉(zhuǎn)動時所承受摩擦力很小，當(dāng)閥芯和閥座相接觸關(guān)閉時，閥芯柔臂在執(zhí)行機構(gòu)推力作用下產(chǎn)生微小彈性變形及彈性漲緊力，使閥芯與閥座接觸更加緊密牢固，因此，偏心旋轉(zhuǎn)閥泄漏量很小。同時關(guān)閉閥門所需的推力與球閥、蝶閥相比要小。偏心旋轉(zhuǎn)半球閥工作原理：偏心旋轉(zhuǎn)調(diào)節(jié)閥是一種結(jié)構(gòu)新穎、流體阻力小的直通型閥體結(jié)構(gòu)，閥芯的回轉(zhuǎn)中心不與旋轉(zhuǎn)軸同心，可減小閥座磨損，延長使用壽命；閥芯后部設(shè)有一個導(dǎo)流翼，有利于流</span><span

style="font-size:16px;">偏心半球閥在管路中主要用來做切斷分配和改變介質(zhì)的流動方向。球閥是近年來被采用的一種新型閥門，它具有以下優(yōu)點：流體阻力小，其阻力系數(shù)與同長度的管段相等。結(jié)構(gòu)簡單、體積小、重量輕。緊密可靠，目前球閥的密封面材料使用塑料、密封性好，在真空系統(tǒng)中也已使用。操作方便，開閉迅速，從全開到全關(guān)只要旋轉(zhuǎn)90°，便于遠(yuǎn)距離的控制。維修方便，球閥結(jié)構(gòu)簡單，密封圈一般都是活動的，拆卸更換都比較方便。在全開或全閉時，球體和閥座的密封面與介質(zhì)隔離，介質(zhì)通過時，不會引起閥門密封面的侵蝕。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。球旋轉(zhuǎn)90度時，在進(jìn)、出口處應(yīng)全部呈現(xiàn)球面，從而截斷流動。偏心半球閥是一種比較新型的球閥類別，它有著自身結(jié)構(gòu)所獨有的一些優(yōu)越性，如開關(guān)無摩擦，密封不易磨損，啟閉力矩小。這樣可減小所配執(zhí)行器的規(guī)格。配以多回轉(zhuǎn)電動執(zhí)行機構(gòu)，可實現(xiàn)對</span><span
