Abstract

Dispositif comprenant une bague d'étanchéité en métal trempé avec une portion centrale d'épaulement avec flasques latéraux et une nervure circonférentielle se terminant par une surface de siège, bague engagée dans une gorge circonférentielle détalonnee de la région de siège de la soupape. Dispositif caractérisé par une gorge dans la surface de siège de la nervure dans laquelle est engagée une bague de siège en matériau plus mou que celui de la bague d'étanchéité, qui se termine, au-delà de l'ouverture, par une surface primaire de siège de soupape destiné à agir en cas de destruction du matériau de la bague de siège. Dispositif applicable à des soupapes de canalisation de fluide à haute température devant résister à l'incendieDevice comprising a hardened metal sealing ring with a central shoulder portion with side flanges and a circumferential rib terminating in a seat surface, ring engaged in a circumferential groove offset from the seat region of the valve. Device characterized by a groove in the seat surface of the rib in which is engaged a seat ring made of material softer than that of the sealing ring, which ends, beyond the opening, in a primary surface valve seat intended to act in the event of destruction of the material of the seat ring. Device applicable to high temperature fluid line valves intended to resist fire
