style="font-size:16px;">球閥主要用于接通或阻斷管路介質(zhì)，尤以用在要求迅速開閉的部位更佳，如應(yīng)急卸荷等處。由于其具有結(jié)構(gòu)簡單，零件少，重量輕，密封性能好等優(yōu)點。結(jié)構(gòu)：主要由閥體、閥蓋、密封閥座、球體和閥桿等組成。帶孔的球體是球閥的問芯，球體受閥桿的轉(zhuǎn)動來控制啟閉，旋轉(zhuǎn)即是全程的開關(guān)。球閥可分為浮動球閥和固定球閥兩大類。浮動球閥的特點是球體可以自由浮動。根據(jù)密封座結(jié)構(gòu)不同又分為固定密封座和帶活動密封座兩種。固定密封閥座的浮動球閥，結(jié)構(gòu)如圖所示，在閥體內(nèi)裝有兩個氟塑制成的固定密封閥座，在兩間座之間夾緊一個由碳鋼或不銹鋼制成的浮動球，球體上有圓形通孔，開后時，通道打開；當(dāng)閥桿轉(zhuǎn)動時，球孔垂直于閥門的通道，靠介質(zhì)的壓力將球體緊壓在后面的閥座上，保證閥門的密封。</span>

style="font-size:16px;">球閥結(jié)構(gòu)簡單，價格也較為低廉，維修費用低且無需潤滑。球閥還有一個優(yōu)點是球體對閥座的密封非常好，通常不會發(fā)生內(nèi)漏。球閥結(jié)構(gòu)原理：1．球閥不受安裝方向的限制，介質(zhì)的流向可任意。流體阻力小，全通徑的球閥基本沒有流阻。2．球閥結(jié)構(gòu)簡單，相對體積小，重量輕，便于維修。3．緊密可靠。它有兩個密封面，而且目前球閥的密封面材料***使用各種塑料，密封性好，能實現(xiàn)完全密封。在真空系統(tǒng)中也已使用。4．球閥適用于經(jīng)常操作，啟閉迅速、輕便。操作方便，開閉迅速，從全開到全關(guān)只要旋轉(zhuǎn)90°，便于遠距離的控制。5．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。6．球閥密封性能好。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。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。</span>

style="font-size:16px;">球閥設(shè)計與制造由于計算機輔助設(shè)計（CAD）和計算機輔助制造（CAM）以及柔性制造系統(tǒng)（FMS）在閥門行業(yè)的應(yīng)用，使球閥的設(shè)計和制造達到一個全新的水平。不但革新了閥門的設(shè)計計算方式，減輕了專業(yè)技術(shù)人員繁重的重復(fù)性常規(guī)設(shè)計工作，使技術(shù)人員有更多的精力用于改進、提高產(chǎn)品性能和新產(chǎn)品開發(fā)，縮短新產(chǎn)品的研究開發(fā)周期、提高勞動生產(chǎn)率，而且在升降桿式金屬密封球閥的研制開發(fā)過程中，由于CAD/CAM的應(yīng)用，出現(xiàn)了由計算機輔助設(shè)計、由計算機輔助數(shù)控機床加工制造的閥桿螺旋扁，使金屬密封球閥在啟閉過程中無任何擦傷和磨損，從而使球閥的密封性和使用壽命**提高。球閥在完全開啟時，流阻很小，幾乎等于零，因此等徑球閥廣泛應(yīng)用于石油天然氣管線中，因為容易清掃管線。由于球閥的球體在啟閉過程中帶有擦拭性，故大多數(shù)球閥可用于帶懸浮固體顆粒的介質(zhì)中，依據(jù)密封圈的材料也可用于粉狀和顆粒狀的介質(zhì)。</span>

style="font-size:16px;">固定球閥的特點1、雙阻塞與排放功能：固定球閥采用彈簧預(yù)緊浮動閥座，無論閥門處于全開或全關(guān)狀態(tài)時，上下游側(cè)的閥座使流體阻斷，閥體中腔滯留物通過排放閥排泄。2、自動泄壓功能：閥門體腔停留介質(zhì)溫度升高而引起異常升壓時，不需通過安全閥，而*靠閥座功能就可自動泄壓，這對保證閥門在輸送液體介質(zhì)時的安全性非常重要。3、防火安全結(jié)構(gòu)：閥門都具備防火安全功能，其設(shè)計、制造均遵循API607和API6FA規(guī)范要求。固定球閥的優(yōu)勢1、密封緊急注脂救護：由于介質(zhì)中的異物或火災(zāi)造成閥座密封意外失效，注脂閥提供了與注脂的快速連接，方便快捷地將密封脂注入到閥座密封部位，緩解泄漏。2、可靠的閥桿密封和低操作力矩：除了設(shè)置標準密封套圈外，填料壓蓋上也設(shè)置了“O”型密封圈，雙重密封保證了閥桿密封的可靠性；增設(shè)的石墨填料和密封脂注入使火災(zāi)后的閥桿泄漏降至比較低。閥桿滑動軸承和止推軸承使閥門操作輕便。3、全通徑或縮徑：可根據(jù)需要選用全通徑或縮徑結(jié)構(gòu)。</span><span
