Abstract

L’invention concerne un circuit de fluide (40) pour turbomachine (1). Le circuit de fluide (40) comprend une première branche de circulation (70a) de fluide et une deuxième branche de circulation (70b) de fluide qui est en parallèle de la première branche de circulation (70a) de fluide. La première branche de circulation (70a) de fluide comprend un premier échangeur thermique (20a) qui est situé dans un premier secteur aubagé de stator. La deuxième branche de circulation (70b) de fluide comprend un deuxième échangeur thermique (20b) qui est situé dans un deuxième secteur aubagé de stator. La première branche de circulation (70a) de fluide comprend une première vanne d’isolement (30a) et un premier dispositif anti-retour (72a) qui est situé en aval du premier échangeur (20a). La première vanne d’isolement (30a) est située en amont du premier échangeur (20a). La première vanne d’isolement (30a) est configurée pour être fermée lorsqu’une valeur absolue de différence de pression entre une pression en amont de la première vanne d’isolement (30a) et une pression en aval de la première vanne d’isolement (30a) est supérieure à une première valeur seuil.
