·軟密封球閥產(chǎn)品詳情

軟密封球閥主要用于截?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最小的一種，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。
