Abstract

Le dispositif comporte une chambre (22) constituée par une partie élargie du passage de traversée (5) dans lequel est disposé le doigt de gant (15). Un clapet (31),monté libre dans la chambre, est constitué par au moins deux lames élastiques (40) comportant des pièces d'appui (42). La chambre comporte une paroi tronçonique (25) contre laquelle s'appuyent les pièces d'appui lorsqu'un fluide parcourt le passage de traversée, ces pièces d'appui se rapprochant pour assurer le maintien transversal du doigt de gant et le débit du fluide étant réduit à une valeur très faible sinon nulle.The device comprises a chamber (22) constituted by an enlarged part of the bushing passage (5) in which the thermowell (15) is arranged. A valve (31), mounted freely in the chamber, is constituted by at least two elastic blades (40) comprising support parts (42). The chamber has a sectional wall (25) against which the support pieces bear when a fluid passes through the passage, these support pieces come together to ensure transverse support of the thimble and the flow of the fluid. being reduced to a very low value if not zero.
