一、Q41F-16P不锈钢软密封球阀用途和性能规范:
Q41F型球阀适用于中、小口径管路的各种压力、温度和介质下控制接通或截断管路介质的启闭装置;靠介质压力将球体压紧在出口端阀座上,其使用压力和通径受到一定限制.采用90°传动,故开关方便迅速,可以实行快速启闭.
二、Q41F-16P不锈钢软密封球阀操作原理和结构说明:
1、球阀通道平整光滑便于管道扫线清洗,可以输送浆液及固体颗粒等介质.
2、采用PTFE（特氟隆）等材料作为密封,具有良好润滑性和弹性,与球体摩擦系小,使用寿命长.
3、启闭迅速,启闭时只需把球体转动90°,方便而迅速.
4.球阀的流体阻力小,全开时球体通道、阀体通道和连接管道的截面积相等,并且成直线想通,介质流过球阀,相当于流过一段直通的管子,在各类阀门中球阀的流体阻力zui小.
5、经配置有手动、蜗轮驱动、气动、电动（防爆）可以实现远程自动控制,能满足用户的各种工况使用要求.
