Abstract

L'invention concerne un dispositif de robinetterie comportant un corps (1), un obturateur (2) manipulé par un arbre (3) guidé dans un col (4) du corps (1) et une manchette d'étanchéité (5) munie d'une collerette (6) qui s'étend sur une certaine longueur le long du col (4). Pour améliorer l'étanchéité du passage d'arbre, un moyen de serrage (7, 8, 9) est positionné
autour de la collerette (6) dans un espace (10) du corps (1). Le moyen de serrage (7, 8, 9) est dimensionné d'une telle manière qu'il exerce un effort sur la collerette (6) et par conséquent sur l'arbre (3). Le moyen de serrage (7, 8, 9) est monté dans l'espace (10) ayant une liberté de mouvement radial et/ou basculant en référence au corps (1). L'invention est particulièrement intéressante pour des robinets à papillon pour liquides agressifs et/ou délicats, tels que des liquides chimiques et des liquides alimentaires. The invention relates to a valve device comprising a body (1), a shutter (2) manipulated by a shaft (3) guided in a neck (4) of the body (1) and a sealing sleeve (5) provided with a flange (6) which extends over a certain length along the neck (4). To improve the sealing of the shaft passage, a clamping means (7, 8, 9) is positioned around the collar (6) in a space (10) of the body (1). The way clamp (7, 8, 9) is dimensioned in such a way that it exerts a force on the flange (6) and therefore on the shaft (3). The way clamp (7, 8, 9) is mounted in the space (10) having a freedom of radial and / or tilting movement with reference to the body (1). The invention is particularly interesting for butterfly valves for liquids aggressive and / or delicate, such as chemical liquids and liquids food.
