Title (EN) FLUID SWIVEL CONNECTOR
(FR) RACCORD TOURNANT DE FLUIDE
Abstract:
(EN) A fluid flow connector for connecting conduits carrying high pressure production fluid, the arrangement comprising a first member (1) carrying a connecting end of the one of the conduits, a second member (2) carrying a connecting end of the other of the conduits, the firt and the second members being movable relative to each other, wherein the first connecting member has: a central core (1) with a plurality of bores (31) formed longitudinally therein; and a plurality of passages (32) formed radially of the core, each radial passage communicating with a respective longitudinal bore, a plurality of annular channels (3) formed between the connecting members, each annular channel providing a fluid flow path to a respective radial passage in the central core, and means for sealing (37) the or each annular channel against leakage of the high pressure production fluid, wherein the sealing means includes: a sealing member activated by differential pressure, and means for supplying a barrier fluid to the side of the sealing member which is remote from the production fluid flow.
(FR) Raccord pour écoulement de fluide permettant de raccorder des conduits acheminant un fluide de production sous haute pression, l'agencement comprenant un premier élément (1) portant une extrémité de raccordement de l'un des conduits, un second élément (2) portant une extrémité de raccordement de l'autre conduit, les premier et second éléments étant mobiles l'un par rapport à l'autre. Le premier élément comporte: une partie centrale (1) renfermant une pluralité d'alésages (31) longitudinaux; et une pluralité de passages (32) formés radialement, chaque passage radial communiquant avec un alésage longitudinal respectif, une pluralité de canaux annulaires (3) formés entre les éléments de raccordement, chaque canal annulaire formant une voie d'écoulement de fluide par rapport à un passage radial respectif de la partie centrale, et un dispositif destiné à étanchéifier (37) un canal ou chaque canal annulaire pour éviter les fuites de fluide de production sous haute pression. Ce dispositif d'étanchéité comprend: un élément d'étanchéité activé par une pression différentielle, et un dispositif destiné à amener un fluide barrière du côté de l'élément d'étanchéité qui est distant de l'écoulement du fluide de production.
