Abstract

Ce robinet comporte un corps 12 dans lequel est monté à rotation un tournant 22 et une queue de manoeuvre 18 mécaniquement accouplée au tournant. Le tournant délimite avec le corps une chambre supérieure 76 et une chambre inférieure 78 situées aux extrémités du tournant. La queue comporte un bourrelet annulaire 21 logé dans la chambre supérieure et en appui contre une bague compensatrice 27 elle-même appliquée contre des joints d'étanchéité annulaires 56 en appui contre la queue et contre un capuchon boulonné 62. Des soupapes 80, 110 sont prévues pour introduire dans la chambre supérieure un fluide lubrifiant d'étanchéité à une pression égale ou supérieure à la pression de la canalisation, de sorte que cette pression agit sur le bourrelet 21 qui comprime les joints d'étanchéité 56 contre le capuchon 62 et contre la queue 18. Application aux canalisations des installations pétrolières.
