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, the opening of the electric rail ball valve
The valve in the closed state, when the actuator drives the piston down to the bottom of the stem angular plane to the sphere sealing surface tilt away from the valve seat, valve stem and valve stem and continue to enhance the spiral groove of the guide pin interactions, the ball began to lift the stem to the limit position without friction rotating 90 degrees ball through holes aligned with the valve channel.
2, electric orbit ball valve closed
When closed, when the actuator drives the valve rod to move downward, the valve stem down, and make the ball began to spin, the stem continues downward, the stem is embedded in the guide pin function of spiral groove, the stem and ball are rotated 90 degrees, is about to close, the ball has been no contact with the valve seat under the condition of rotating 90 degrees stem continue to move down, the ball swing, and mechanical wedge pressure pressed on the seat, the valve seat sealing surface to generate elastic deformation, closely cooperate with the sphere sealing surface, zero leakage so as to ensure safe and reliable.
