Track hard seal ball valve works

Track hard seal ball valve works: The principle of the cam makes the valve ball in the rotation and seat sealing surface from the rotation, then the ball in place to the valve seat to achieve sealing. When the valve is in the fully open position, turn the handwheel instantaneously, and with the stem nut and thrust bearing, the stem starts to descend and the ball begins to rotate. Connect the rotating hand wheel, the precision helical curve groove track on the valve stem, interacting with the guide pin embedded in it to drive the ball body to rotate clockwise with the valve stem. When the valve is about to be closed, the valve stem rotates the ball by 90 ° without any friction with the seat sealing surface. Continue to turn the hand wheel, and then descend again through the stem of the valve stem at the bottom of the cam structure mechanical pressure ball, the ball sealing surface and the valve seat sealing surface close contact, so as to achieve the purpose of sealing. When the ball valve is in the fully-closed position, turn the handwheel counterclockwise. With the cooperation of the stem nut and the thrust bearing, the stem starts to rise and the ball starts to rotate. Turn the handwheel continuously, the valve stem will move toward the valve seat while it is rising. When the rail hard seal ball valve is to be opened, the precision helical groove on the valve stem engages with the guide pin embedded in it to drive the ball to rotate counter-clockwise without any friction with the sealing surface of the valve seat. Continue to turn the handwheel, when the stem rose to the limit position, this time the ball has also been inverted with the stem 90 °, the valve is already in full position. Orbital seal ball valve structural features: the traditional ball valve, either floating or fixed, the ball and the valve always contact, the switching torque, sealing surface easily damaged, the track ball on the opening and closing, the ball deflected first-delta angle, Then turn, the whole process of switching the ball and the seat off, so the seat will not be scratched, and opening and closing torque is small.
