style="font-size:16px;">球閥適用場合由于球閥通常用橡膠、尼龍和聚四氟乙烯作為閥座密封圈材料，因此它的使用溫度受到閥座密封圈材料的限制。球閥的截止作用是靠金屬球體在介質(zhì)的作用下，于塑料閥座之間相互壓緊來完成的（浮動球球閥）。閥座密封圈在一定的接觸壓力作用下，局部地區(qū)發(fā)生彈塑變形。這一變形可以補償球體的制造精度和表面粗糙度，保證球閥的密封性能。又由于球閥的閥座密封圈通常采用塑料制成，故在選擇球閥的結(jié)構(gòu)和性能上，要考慮球閥的耐火和防火，特別是在石油、化工，隴南球閥價格、冶金等部門，在易燃、易爆介質(zhì)的設(shè)備和管路系統(tǒng)中使用球閥，更應(yīng)注意耐火和防火。通常，在雙位調(diào)節(jié)、密封性能嚴格、泥漿、磨損，隴南球閥價格、縮口通道、啟閉動作迅速（1/4轉(zhuǎn)啟閉）、高壓截止（壓差大）、低噪聲、有氣穴和氣化現(xiàn)象、向大</span><span

style="font-size:16px;">浮動球閥適用于：化工，石油，天然氣，冶金，等行業(yè)及含硫化氫介質(zhì)，雜質(zhì)多，腐蝕嚴重的天然氣長輸管線。浮動球閥的主要結(jié)構(gòu)特點為：1.閥門設(shè)有開、關(guān)位置指示;2.鎖定裝置;3.閥桿防飛結(jié)構(gòu);4.防靜電裝置;5.防火結(jié)構(gòu);6.獨特閥座密封結(jié)構(gòu);7.中法蘭(閥體與左體連接部)無外漏結(jié)構(gòu)。球體有一個稱為固定球閥的固定軸球閥。固定球閥主要用于高壓大口徑。根據(jù)閥座密封圈的不同安裝情況，固定球閥可以有兩種結(jié)構(gòu)：密封在球體前面的閥座和密封在球體內(nèi)的閥座。球閥是生產(chǎn)生活中常用的閥門之一；主要用于食品、化工、石油、電力等行業(yè)。球閥在管路中主</span><span

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;">普通閥座的特點是在預(yù)緊力或流體壓力作用下閥座與球體壓緊，并使閥座材料產(chǎn)生彈塑性變形而達到密封，其密封效果取決于閥座在流體壓力或預(yù)緊力的作用下補償球體圓度和表面微觀不平度的能力。因此，閥座與球體之間必須具有足夠大的密封比壓。彈性閥座借助于彈性元件，如金屬彈簧架和彈簧等，在預(yù)緊力或流體壓力下產(chǎn)生彈性變形，以補償溫差、壓力和磨損等外界條件變化對球體密封性能的影響。彈簧組合式閥座是沿閥門通道橫向截面圓周均布一組壓縮彈簧或*用一只碟型彈簧的推力，始終保持閥座壓緊球體而達到預(yù)緊狀態(tài)?；钊介y座是依靠進口介質(zhì)壓力產(chǎn)生密封力，閥座被推動壓緊球體，密封圈產(chǎn)生彈塑性變形實現(xiàn)密封。截斷泄放閥座在閥腔內(nèi)的壓力異常升高到大于下游端壓力時，形成的壓差作用產(chǎn)生向外推</span><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>
