style="font-size:16px;">球閥的主要功能是切斷或接通管道中的流體通道。球閥的工作原理是借助驅(qū)動裝置在閥桿上端施加一定的轉(zhuǎn)矩傳給球體，使其旋轉(zhuǎn)90°，完成開啟或關(guān)閉閥門的動作。球閥閥座的密封原理依其結(jié)構(gòu)而異，常用的閥座結(jié)構(gòu)可分為固定閥座浮動球體與浮動閥座固定球體兩大類。當(dāng)閥座固定球體浮動時，在流體壓力作用下球體在流體流動方向產(chǎn)生位移，使它與閥后閥座密封而更緊密地接觸，即在該密封面上的比壓增大，形成單面密封，同時，閥前閥座密封面上的比壓相應(yīng)減小，往往不保證密封。當(dāng)閥座浮動球體固定時，流體壓力不能使球體產(chǎn)生位移，而是閥座借助于彈簧或流體推力壓向球體，建立密封比壓。普通閥座的特點(diǎn)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(dá)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(bǔ)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。</span> 靈臺球閥廠家球體繞閥體中心線作旋轉(zhuǎn)來達(dá)到開啟、關(guān)閉的一種閥門。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="靈臺球閥廠家,球閥"

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(diǎn)。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(diǎn)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>
