Abstract

L'invention concerne un robinet sphérique à boisseau sphérique disposé entre des bagues d'étancheité et à élément de commande ayant un orifice d'étranglement correspondant à une caractéristique de commande désirée. Selon l'invention, les bagues d'étanchéité 24, 26 sont disposées à une certaine distance radiale par rapport aux trous de passage 20, 22 prévus dans le corps 14 de robinet et, pour chaque bague d'étanchéité 24, 26, est prévue, dirigée radialement vers l'intérieur, une saillie ou arête annulaire 27, du côté du corps de robinet et s'étendant vers la surface du boisseau suffisamment pour qu'en position de fermeture du boisseau sphérique, les bagues d'étanchéité ne soient soumises à l'action du fluide en circulation qu'à travers une fente annulaire, et l'élément de commande 32, 42, 44 n'est usiné avec précision, pour correspondre à la surface du boisseau sphérique, que le long d'une zone annulaire étroite 38, 48, 52 située radialement vers l'extérieur, zone par rapport à laquelle la partie restante de l'élément de commande est en retrait.The invention relates to a ball valve with a ball valve disposed between sealing rings and a control element having a throttle orifice corresponding to a desired control characteristic. According to the invention, the sealing rings 24, 26 are arranged at a certain radial distance from the passage holes 20, 22 provided in the valve body 14 and, for each sealing ring 24, 26, is provided , directed radially inwards, a projection or annular ridge 27, on the side of the valve body and extending towards the surface of the valve sufficiently so that in the closed position of the ball valve, the sealing rings are not subjected to the action of the circulating fluid only through an annular slot, and the control element 32, 42, 44 is machined with precision, to correspond to the surface of the ball valve, only along a zone narrow annular 38, 48, 52 located radially outwards, the area relative to which the remaining part of the control element is recessed.
