max-height: 320px;" alt="清水球閥廠家供應(yīng),球閥" src="https://tyunfile.71360.com/UploadFile/gscyhwz/637318945680078125/9755009.png"></div><p> <span 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> </p><p> <span style="font-size:16px;">球閥的性能原理①球閥性能出色，擁有流體阻力小(全通徑流道閥體阻力系數(shù)幾乎與管道相同、不會造成壓力損失)。②結(jié)構(gòu)簡約，閥體對稱、體積小、可雙向流動、雙向密封。③密封可靠(尤其是閥座密封面采用非金屬材料時)④操作方便、啟閉迅速、轉(zhuǎn)動90度即可完成閥門的啟閉，便于遠(yuǎn)距離控制。⑤維修方便，閥座密封圈一般都是活動的，拆換方便，如果采用上裝式結(jié)構(gòu)，可在線更換。⑥閥門在全開或者全關(guān)位置，密封副與介質(zhì)完全隔離，高速通過的介質(zhì)不會沖蝕密封副。⑦球體在啟閉時是旋轉(zhuǎn)擦拭的過程，所以多數(shù)結(jié)構(gòu)的球閥可以用于帶懸浮固體顆粒的介質(zhì)，選用合適的耐磨的閥座密封材料，也可用于粉狀介質(zhì)。⑧直通式球閥用作切斷用，使用***、三通、四通等球閥用于分配介質(zhì)和改變介質(zhì)流向、V型可做節(jié)流用。⑨全通徑球閥全開式易于清掃球通過清掃管線，在石油，天然氣管道中***使用。⑩適用范圍廣、工作壓力從真空至高壓，公稱直徑DN8~3000，工作溫度為-254~815攝氏度。</span>
