Abstract
Dispositif anti-retour monté sur l'une des canalisations d'alimentation en gaz d'un chalumeau de soudure. A l'opposé du joint usuel 15 destiné à s'opposer à ce qu'une contre-pression accidentelle soit transmise au générateur, le clapet mobile 14 est pourvu d'une garniture 17 coopérant avec un siège 6a pour obturer automatiquement l'écoulement du gaz en cas de brusque chute de pression consécutive à la rupture de la canalisation reliant le dispositif au chalumeau. Industrie des accessoires pour installations de soudure.
