详细信息| 询价留言球阀主要用于截断或接通介质,也可用于流体的调节与控制。与其它阀类相比,球阀具有如下的一些优点:
1、流体阻力小,球阀是所有阀类中流体阻力*小的一种,即使是缩径球阀,其流体阻力也相当小。2、开关迅速、方便,只要阀杆转动90°,球阀就完成了全开或全关动作,很容易实现快速启闭。3、密封性能好。球阀阀座密封圈一般采用聚四氟乙烯等弹性材料制造,易于保证密封,而且球阀的密封力随着介质压力的增加而增大。4、阀杆密封可靠。球阀启闭时阀杆只作旋转运动,因此阀杆的填料密封不易被破坏,而且阀杆倒密封的密封力随着介质压力的增加而增大。5、球阀的启闭只做90°转动,故容易实现自动化控制和远距离控制,球阀可配置气动装置、电动装置、液动装置、气液联动装置或电液联动装置。6、球阀通道平整光滑,不易沉积介质,可以进行管线通球。
