The invention relates to a sealing and connection device for the external pipes of a cryogenic liquid tank in the form of a single-piece, cast stainless steel sub-assembly (1) comprising a main disk-shaped part (4) which is mounted on a flange (2) of the tank (3). Said sub-assembly defines at least two fluid flow channels (8, 9), which are typically used for filling, airing and extracting gaseous and liquid phases and which are heated by atmospheric heaters (23; 30) in order to supply (31) a controlled gaseous flow. The invention is particularly suitable for cryogenic tanks of medical oxygen for oxygen therapy.
Le dispositif comporte un sous-ensemble monobloc (1) en acier inoxydable
moulé comportant une partie principale en forme de disque (4) montée sur une
bride (2) du réservoir (3) et définissant au moins deux canaux (8, 9) de
passage de fluide, typiquement pour le remplissage, la mise à l'air, et le
soutirage de phases liquides et gazeuses réchauffées par des réchauffeurs
atmosphériques (23 ; 30) pour la fourniture (31) d'un flux gazeux contrôlé.
Application notamment aux réservoirs cryogéniques d'oxygène médical pour
oxygénothérapie.
