style="font-size:16px;">偏心半球閥在管路中主要用來(lái)做切斷分配和改變介質(zhì)的流動(dòng)方向。球閥是近年來(lái)被采用的一種新型閥門(mén)，它具有以下優(yōu)點(diǎn)：流體阻力小，其阻力系數(shù)與同長(zhǎng)度的管段相等。結(jié)構(gòu)簡(jiǎn)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(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。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。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(mén)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(shí)，在進(jìn)、出口處應(yīng)全部呈現(xiàn)球面，從而截?cái)嗔鲃?dòng)。偏心半球閥是一種比較新型的球閥類(lèi)別，它有著自身結(jié)構(gòu)所獨(dú)有的一些優(yōu)越性，如開(kāi)關(guān)無(wú)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(dòng)執(zhí)行機(jī)構(gòu)，可實(shí)現(xiàn)對(duì)</span><span

style="font-size:16px;">偏心半球閥的維修方法注意事項(xiàng)：偏心半球閥在關(guān)閉狀態(tài)下，閥體內(nèi)部依舊存在受壓流體。維修前，解除管線壓力并使閥門(mén)處于打開(kāi)位置。新零件在裝配前也需清洗干凈。維修前，將執(zhí)行機(jī)構(gòu)與支架脫離。非金屬零件清洗后應(yīng)立即從清洗劑中取出，不得長(zhǎng)時(shí)間浸泡。清洗后需待被洗壁面清洗劑揮發(fā)后(可用未浸清洗劑的綢布擦)進(jìn)行裝配，但不得長(zhǎng)時(shí)間擱置，否則會(huì)生銹、被灰塵污染。必須先查明球閥上、下游管道確已卸除壓力后，才能進(jìn)行拆卸分解操作。分解及再裝配時(shí)必須小心防止損傷零件的密封面，特別是非金屬零件，取出O型圈時(shí)宜使用**工具。使用潤(rùn)滑脂潤(rùn)滑。潤(rùn)滑脂應(yīng)與偏心半球閥金屬材料、橡膠件、塑料件及工作介質(zhì)均相容。工作介質(zhì)為燃?xì)鈺r(shí)，可用例如特221潤(rùn)滑脂。在密封件安裝槽的表面上涂一薄層潤(rùn)滑脂，在橡膠密封件上涂一薄層潤(rùn)滑脂，閥桿的密封面及摩擦面上涂一薄層潤(rùn)滑脂。維修前，斷開(kāi)電源或氣源。裝配時(shí)法蘭上的螺栓必須對(duì)稱、逐步、均勻地?cái)Q緊。清洗劑應(yīng)與球閥中的橡膠件、塑料件、金屬件及工作介質(zhì)(例如燃?xì)?等均相容。工作介質(zhì)為燃?xì)鈺r(shí)，可用汽油(GB484-89)清洗金屬零件。非金屬零件用純凈水或酒精清洗。</span>

style="font-size:16px;">偏心半球閥具有切削功能，1、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(guò)偏心軸旋轉(zhuǎn)90°來(lái)實(shí)現(xiàn)閥門(mén)的啟閉，起到截?cái)嘟橘|(zhì)的作用。2、偏心半球閥保證了閥門(mén)在開(kāi)啟或關(guān)閉過(guò)程中，閥座和球冠沒(méi)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(mén)流道中心線偏離一個(gè)偏心距。在閥門(mén)開(kāi)啟時(shí)，曲軸轉(zhuǎn)過(guò)一個(gè)很小的角度，球冠就會(huì)離開(kāi)閥座，球冠和閥座不再接觸；反之，在閥門(mén)關(guān)閉過(guò)程中，只有在關(guān)閉瞬間，球冠才和閥座接觸。3、偏心半球閥采用上裝式結(jié)構(gòu)，在維修過(guò)程中，不需從管線中拆卸下來(lái)，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(mén)能夠在線維修。4、偏心半球閥在開(kāi)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)。5、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(wú)任何振動(dòng)，殼體試驗(yàn)按國(guó)家</span><span style="font-size:16px;">標(biāo)準(zhǔn)GB13927-1992執(zhí)行。6、偏心半球閥不允許有外漏，上、下軸端應(yīng)采用至少2道O形密封圈密封。7、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(shù)枝、紡織袋等）切斷，保證閥門(mén)正常啟閉。</span></p><p> <span
