style="font-size:16px;">偏心半球閥由閥體、偏心軸、閥蓋、球冠、軸套、閥座等主要部件組成，通過偏心軸旋轉(zhuǎn)90°來實(shí)現(xiàn)閥門的啟閉，起到截?cái)嘟橘|(zhì)的作用。偏心半球閥保證了閥門在開啟或關(guān)閉過程中，閥座和球冠沒有相互摩擦，偏心半球閥采用偏心曲軸，使得球冠中心線與閥門流道中心線偏離一個(gè)偏心距。在閥門開啟時(shí)，曲軸轉(zhuǎn)過一個(gè)很小的角度，球冠就會(huì)離開閥座，球冠和閥座不再接觸；反之，在閥門關(guān)閉過程中，只有在關(guān)閉瞬間，球冠才和閥座接觸。偏心半球閥采用上裝式結(jié)構(gòu)，在維修過程中，不需從管線中拆卸下來，只需卸下閥蓋上的螺栓，取下閥蓋，從而可以取出偏心軸，這樣保證了閥門能夠在線維修。偏心半球閥在開啟時(shí)應(yīng)保證流道完全暢通，在運(yùn)行時(shí)水頭損失小。球體采用半圓形通道，具有良好的流通性能和線性調(diào)節(jié)性能，且雜質(zhì)不會(huì)沉積在閥體中腔內(nèi)。偏心半球閥應(yīng)有足夠的強(qiáng)度，偏心曲軸采用固定球結(jié)構(gòu)，在高流速下無任何振動(dòng)，殼體試驗(yàn)按國家標(biāo)準(zhǔn)GB13927-1992執(zhí)行。偏心半球閥</span><span style="font-size:16px;">不允許有外漏，上、下軸端應(yīng)采用至少2道O形密封圈密封。偏心半球閥具有切削功能，在關(guān)閉時(shí)能將介質(zhì)中雜物（樹枝、紡織袋等）切斷，保證閥門正常啟閉。</span> 傳統(tǒng)的偏心半球閥主要零件為閥體、閥座、閥芯、閥座調(diào)整墊片以及閥軸。</p><div
