Abstract

Vanne cryogénique avec réduction du transfert thermique Vanne cryogénique (1), comportant : un clapet (4), une tête de commande (8), un corps de vanne (2) comportant un siège (3) de clapet et une partie tubulaire (10), la partie tubulaire (10) se raccordant à la tête de commande (8), une tige d’actionnement (7) reliant le clapet (4) à la tête de commande (8), mobile au sein de la partie tubulaire (10) du corps de vanne, une pluralité de rondelles (40) espacées sur la longueur de la tige (7) et obturant chacune sensiblement l’espace entre la tige et la partie tubulaire du corps de vanne, de façon à limiter les échanges thermiques par convection le long de la tige. Figure pour l’abrégé : Fig. 1
