style="text-indent:25px">氣動(dòng)球閥流體阻力小，球閥是所有閥類中流體阻力較小的一種，即使是縮徑球閥，其流體阻力也相當(dāng)小。開關(guān)迅速、方便，只要閥桿轉(zhuǎn)動(dòng)90°，球閥就完成了全開或全關(guān)動(dòng)作，很容易實(shí)現(xiàn)快速啟閉。密封性能好。球閥閥座密封圈一般采用聚四氟乙烯等彈性材料制造，易于保證密封，而且球閥的密封力隨著介質(zhì)壓力的增加而增大。閥桿密封可靠。球閥啟閉時(shí)閥桿只作旋轉(zhuǎn)運(yùn)動(dòng)，因此閥桿的填料密封不易被破壞，而且閥桿倒密封的密封力隨著介質(zhì)壓力的增加而增大。球閥的啟閉只做90°轉(zhuǎn)動(dòng)，故容易實(shí)現(xiàn)自動(dòng)化控制和遠(yuǎn)距離控制，球閥可配置氣動(dòng)裝置、電動(dòng)裝置、液動(dòng)裝置、氣液聯(lián)動(dòng)裝置或電液聯(lián)動(dòng)裝置。</p><p style="text-indent:25px">氣動(dòng)球閥的材質(zhì)：氣動(dòng)球閥的球體是彈性的。球體和閥座密封圈都采用金屬材料制造，密封比壓很大，依靠介質(zhì)本身的壓力已達(dá)不到密封的要求，必須施加外力。這種閥門適用于高溫高壓介質(zhì)。彈性球體是在球體內(nèi)壁的下端開一條彈性槽，而獲得彈性。當(dāng)關(guān)閉通道時(shí)，用閥桿的楔形頭使球體漲開與閥座壓緊達(dá)到密封。在轉(zhuǎn)動(dòng)球體之前先松開楔形頭，球體隨之恢復(fù)原原形，使球體與閥座之間出現(xiàn)很小的間隙，可以減少密封面的摩擦和操作扭矩。氣動(dòng)球閥按其通道位置可分為直通式，三通式和直角式。后兩種球閥用于分配介質(zhì)與改變介質(zhì)的流向。氣動(dòng)閥門的使用手冊(cè)。</p><div
