GQ947Y electric rail ball valve is a new type of practical products, with a rotating ball core 90 degrees set off a high-tech type of ball valve. At present, the Q type ball valve are given under preload ball and valve seat friction for opening and closing, often resulting in damage to the sealing surface, the valve leakage and the blocking phenomenon is the common defects on the track ball update design makes the new ball ball valve core is rotated 90 degrees and then switch, the ball valve can the sealing surface friction free combination, to achieve the purpose of security leak, and prolong the service life of the valve play.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, caliber. Specific please contact or online advisory contact
1、电动轨道球阀的开启
调节阀在关闭的状态下,当执行机构带动阀杆向上运动,其阀杆底部的角形平面使球体密封面倾离阀座,阀杆继续提升并与阀杆螺旋槽内的导销相互作用,使球体开始无摩擦旋转90°直至阀杆提升到极限位置,球体通孔对准阀门通道。
2、 电动轨道球阀的关闭
关闭时,当执行机构带动阀杆向下运动,阀杆下移,并使球体开始旋转,阀杆继续下移,阀杆受到嵌于螺旋槽内的导向销作用,使阀杆和球体同时旋转90°,快要关闭时,球体已在与阀座无接触的情况下旋转90°,阀杆继续下移 ,球体摆动,并受机械楔紧施压压紧在阀座上,使阀座密封面产生弹性变形,与球体密封面紧密配合,从而保证安全、可靠的零泄漏。
