Title
(EN) BALL VALVE
(FR) VANNE A BOISSEAU SPHERIQUE
Abstract
(EN)
The invention relates to a ball valve of the type comprising a ball member provided with two axially displaceable sleeves adapted to be displaced outwards to sealing engagement against seats provided in the surrounding valve housing in the open position of the valve, so as to form a flow passage through the valve, and which comprises a hollow drive axle for the rotary movement of the ball member between the open and a closed position, and a drive spindle through the hollow drive axle adapted to bringing about the axial displacement movement of the sleeves. On the drive spindle and for rotation together with it there are provided two preferably disc-shaped, first cam members on either side of the sleeves, and the sleeves are provided with corresponding and cooperating second cam members for the axial displacement by rotation of the drive spindle in relation to the ball member. The ball valve has particularly interesting uses in the oil related industry and on oil rigs or the like.
