Abstract

L'invention concerne un robinet à obturateur sphérique. Le robinet 10 comprend un obturateur 13 muni sur chacune des ses moitiés opposées de surfaces d'étanchéité sphériques 13S décentrées par rapport au point de pivotement de l'obturateur, respectivement à droite et à gauche de ce point de sorte que ces surfaces se déplacent sur un arc excentrique lorsque l'obturateur 13, qui est monté sur des tourillons 13B, 13T, est déplacé en rotation. Les surfaces sphériques 13S coopèrent avec des dispositifs d'étanchéité respectifs 14 qui comprennent chacun un élément d'étanchéité primaire statique et un élément d'étanchéité secondaire dynamique sensible à la pression de la ligne amont pour déplacer l'élément d'étanchéité primaire en appui étanche contre l'obturateur. L'invention est applicable, notamment, aux robinets utilisés dans des applications cryogéniques et haute pression.The invention relates to a ball valve. The valve 10 comprises a shutter 13 provided on each of its opposite halves with spherical sealing surfaces 13S off-center with respect to the pivot point of the shutter, respectively to the right and to the left of this point so that these surfaces move on an eccentric arc when the shutter 13, which is mounted on journals 13B, 13T, is rotated. The spherical surfaces 13S cooperate with respective sealing devices 14 which each comprise a static primary sealing element and a dynamic secondary sealing element responsive to the pressure of the upstream line to move the primary sealing element in abutment. waterproof against the shutter. The invention is applicable, in particular, to valves used in cryogenic and high pressure applications.
