style="font-size:16px;">偏心半球閥在開啟時應(yīng)保證流道完全暢通，在運行時水頭損失小。球體采用半圓形通道，具有良好的流追性能和線性調(diào)節(jié)性能，且雜質(zhì)不會沉積在閥體中腔內(nèi)。偏心半球閥應(yīng)有足夠的強度，偏心曲軸采用固定球結(jié)構(gòu)，在高流速下無任何振動。偏心半球閥不允許有外漏，上、下軸端應(yīng)采用至少2道形密封圈密封。偏心半球閥具有切削功能，在關(guān)閉時能將介質(zhì)中雜物(樹枝、紡織袋等)切斷，保證閥門正常啟閉。使用范圍:可適用于水、汽、油品等系統(tǒng)中適用于水壩底部放空閥和控制閥（高流速狀態(tài))。適用于泵輸送系統(tǒng)的閥門，如加壓系統(tǒng)，中央空調(diào)系統(tǒng)。</span><span style="font-size:16px;">可配置成安全閥、流量控制閥、爆管閥、減壓閥等。適用于自來水系統(tǒng)，煤氣系統(tǒng)、天然氣系統(tǒng)等地下管線（高度小)。</span> 偏心半球閥是一種比較新型的球閥類別。武威偏心半球閥費用</p><p style="text-indent:25px">電動偏心半球閥和氣動偏心半球閥有何區(qū)別？武威偏心半球閥費用</p><p> <span 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)有一個導流翼，有利于流</span><span
