Definitions

  • the technical result of the present invention is to expand the arsenal of means to compensate for the deviation of the dimensions of the body parts of the ball valve, the grooves in them for installing ring seals mating with the ball locking element of the ball valve, assembly errors, and also to increase the service life of the product with the ball locking element due to ensure greater durability of the O-rings.
  • the sealing element has, on the side opposite to the side in contact with the outer surface of the spherical locking element, a flat annular surface mating on the outer edge with a cylindrical surface, by which the sealing element mates, respectively, with the flat annular and cylindrical surfaces of the groove.
  • the housing 1 and part 5 are made with annular grooves 8, 9, in which the annular sealing elements 10 are located, between which there is a ball locking element 2, which is tightly clamped, deforming the annular sealing elements 10, contacting with the outer surface 1 1 of the ball locking element 2, thereby achieving the tightness of the ball valve.

Abstract

L'invention concerne des systèmes de chauffage et d'alimentation en eau. L'unité d'étanchéité comprend une entaille annulaire formée dans le corps et comportant un élément d'étanchéité entrant en contact avec la surface externe de l'élément d'obturation à boule. L'entaille est formée dans a section de la surface angulaire et possède une surface annulaire plane en contact sur son bord externe avec la surface cylindrique. Sur le bord interne de la surface annulaire plane se trouve une protubérance angulaire annulaire derrière laquelle se trouve une surface conique qui s'étend dans la direction radiale par rapport à l'axe de l'entaille et dans la direction longitudinale vers le côté s'éloignant de l'élément d'étanchéité annulaire, et qui forme avec le plan de la surface plane un angle aigu. L'élément d'étanchéité comprend une surface plane en contact le long du bord externe avec une surface et l'élément d'étanchéité est en contact respectivement avec les surfaces planes et cylindrique de l'entaille. La protubérance s'étend dans la direction radiale dans la zone de la partie médiane sur la largeur de la surface annulaire plane de l'élément d'étanchéité. Le résultat technique consiste en un plus large éventail des moyens de compensation d'écarts de taille des pièces du corps d'un robinet à boule.
