            J41W/Y不锈钢法兰截止阀 
            球阀是用带圆形通孔的球体作启闭件,球体随阀杆转动,以实现启闭动作的阀门。  
            1、球阀的主要优点  
            1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,并且成直线相通,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最小。  
            2启闭迅速,启闭时只需把球体转成90 0 ,方便而迅速  
            3结构较简单,体积较小,重量较轻。特别是它的高度远小于闸阀和截止阀。  
            4密封性能较好。球阀一般采用具有弹性的软质密封圈。 |
