The high-pressure output (2) of a donor container is coupled to a user system (11) by means of a main transfer tube (4) through a pilot valve (5) controllable by an auxiliary line (6) which is connected (12) to an auxiliary circuit of the system (11), extends along the main tube (15) and is fixed thereto by the reduced length thereof at several distinct points (Si). In such a way, the rupture or inflammable leakage of the tube (4) generates the tearing off or meting of the auxiliary line (6) in such a way that the output valve (5) is immediately closed. Said invention is particularly suitable for an inflammable gas supply to stationary plants.
La sortie haute pression (2) du réservoir donneur est reliée à l'installation utilisatrice (11) par une tubulure principale de transfert (4) via une vanne pilotée (5) commandée par une ligne auxiliaire (6) reliée (12) à un circuit auxiliaire de l'installation (11) et s'étendant le long de la tubulure principale (15) en étant solidarisée à cette dernière, avec une longueur raccourcie, en plusieurs points distants (Si). Ainsi, toute rupture ou fuite inflammable de la tubulure (4) provoque un arrachement ou une fusion de la ligne auxiliaire (6) provoquant la fermeture immédiate de la vanne de sortie (5). Application notamment à la fourniture de gaz inflammable à des installations fixes.
