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(dòng)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(kāi)啟或關(guān)閉閥門(mén)的動(dòng)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(dòng)球體與浮動(dòng)閥座固定球體兩大類(lèi)。當(dāng)閥座固定球體浮動(dòng)時(shí)，在流體壓力作用下球體在流體流動(dòng)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(shí)，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(dòng)球體固定時(shí)，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>
