style="font-size:16px;">球閥的結(jié)構(gòu)大體上主要由閥體、球體、閥座密封圈、閥桿以及驅(qū)動(dòng)裝置等組成：由于它的啟閉件是球體，在管路中截流時(shí)，介質(zhì)容易對(duì)球體的邊緣造成沖蝕，所以球閥只做全開(kāi)或全關(guān)，同時(shí)它還具有以下特點(diǎn)：1、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(méi)有流阻。通道平整光滑，不易沉積介質(zhì)。2、密封性能好。球閥有兩個(gè)密封面，閥座密封圈一般采用聚四氟乙烯等材料，密封性好，而且球閥的密封力隨著介質(zhì)壓力的增加而增大，高真空及高壓力均可使用。3、球閥啟閉迅速、輕便。從全開(kāi)到全關(guān)只要旋轉(zhuǎn)90°。4、閥桿密封可靠，球閥啟閉時(shí)閥桿只做旋轉(zhuǎn)運(yùn)動(dòng)，因此閥桿的填料密封不易被破壞，其密封力也會(huì)隨著介質(zhì)壓力的增加而增大。5、球閥的啟閉只做90°轉(zhuǎn)動(dòng)，容易實(shí)現(xiàn)自動(dòng)化控制和遠(yuǎn)距</span><span
