style="text-indent:25px">不銹鋼球閥主要用于截?cái)嗷蚪油ń橘|(zhì)，也可用于流體的調(diào)節(jié)與控制。與其它閥類相比，球閥具有如下的一些優(yōu)點(diǎn)： 1、流體阻力小，球閥是所有閥類中流體阻力**小的一種，即使是縮徑球閥，其流體阻力也相當(dāng)小。 2、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。 3、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。 4、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。 5、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。 6、球閥通道平整光滑，不易沉積介質(zhì)，可以進(jìn)行管線通球。</p><div

Q647型氣動(dòng)固定式球閥是新一代高性能球閥，適用于長(zhǎng)輸管線和一般工業(yè)管線，其強(qiáng)度、安全性、耐惡劣環(huán)境性等在設(shè)計(jì)時(shí)進(jìn)行了特殊考慮，適用于各種腐蝕性和非腐蝕性介質(zhì)。它與浮動(dòng)球閥相比，工作時(shí)，閥前流體壓力在球體上產(chǎn)生的作用力全部傳遞給軸承，不會(huì)使球體向閥座移動(dòng)，因而閥座變形小，密封性能穩(wěn)定、使用壽命長(zhǎng)，適用于高壓、大口徑場(chǎng)合。先進(jìn)的彈簧預(yù)閥座組件，具有自緊特性，實(shí)現(xiàn)上游密封。每閥有兩個(gè)閥座，每個(gè)方向都能密封因而安裝沒(méi)有流向限制，是雙向。本閥有二塊式和三塊式兩種閥體結(jié)構(gòu)，中法蘭用螺栓連接，密封采用增強(qiáng)聚四氟乙烯鑲?cè)氩讳P鋼圈內(nèi)，鋼圈后部設(shè)有彈簧保證閥座緊貼球體，保持密封。上下閥桿均設(shè)有PTFE軸承，減少磨擦，操作省力，小軸底部沒(méi)有調(diào)整片，保證球與密封圈的接處位置。采用全通徑的結(jié)構(gòu)使閥門流量孔么與管線內(nèi)徑一致，以便管線清掃。
