The invention relates to a dual-safety valve (1) that is made up of two valves (2, 3) arranged in a housing (4), whereby two axially displaceable disks (9, 12) of said valves are arranged coaxially in relation to each other and are raised above their respective valve seat as a result of an axial movement in an opening direction (16), counter to the pressure exerted by a first or second closing spring (11, 14). The first outer valve disk (9) in the direction of flow of the dual safety valve surrounds the second (inner) valve disk (12) and both valve seats are brought together to form a common valve seat (8) that surrounds the only valve opening (5). This reduces overall axial height and simplifies assembly of the dual safety valve (1).

L'invention concerne une double vanne de sécurité (1) comportant deux vannes (2, 3) logées dans un carter (4), dont les deux disques (9, 12) déplaçables axialement sont disposés coaxialement l'un par rapport à l'autre et se soulèvent respectivement de leur siège respectif par un mouvement axial dans le sens d'ouverture (16) à l'encontre de la pression d'un premier ou d'un deuxième ressort de fermeture (11, 14). Le premier disque de vanne (9) (extérieur) dans le sens d'écoulement de la double vanne de sécurité (1) entoure le deuxième disque de vanne (12) (intérieur), et leurs deux sièges de vanne sont réunis en un siège de vanne (8) commun qui entoure l'ouverture de vanne unique (5). Il est ainsi possible de réduire la hauteur d'encombrement axiale et de simplifier le montage de la double vanne de sécurité.
