Title (EN) FUEL TIP WITH INTEGRATED FLASHBACK ARRESTOR
(FR) EMBOUT DE CARBURANT À DISPOSITIF ANTIRETOUR DE FLAMME INTÉGRÉ
Abstract:
(EN) Provided herein are flashback arrestors disposed proximate the head of a cutting torch for restricting flashback into the torch head. In one approach, a torch assembly is provided including a torch head having a gas passageway formed within a body of the torch head, and a tip coupled to a distal end of the torch head. In some approaches, the tip has a proximal end and a distal end, the distal end of the tip including an exit orifice and the proximal end of the tip having a set of openings in fluid communication with the gas passageway for delivering a gas towards the exit orifice. The torch assembly further includes a filter coupled to the tip at the proximal end thereof, the filter disposed between the set of openings and the gas passageway for restricting flashback into the torch head.
(FR) L'invention concerne des dispositifs antiretour de flamme agencés à proximité de la tête d'un chalumeau coupeur pour limiter le retour de flamme dans la tête du chalumeau. Dans un mode de réalisation, l'invention concerne un ensemble de chalumeau qui comprend une tête de chalumeau comportant un passage de gaz formé à l'intérieur d'un corps de la tête de chalumeau, et un embout raccordé à une extrémité distale de la tête de chalumeau. Dans certains modes de réalisation, l'embout comporte une extrémité proximale et une extrémité distale, l'extrémité distale de l'embout comprenant un orifice de sortie et l'extrémité proximale de l'embout comportant un ensemble d'ouvertures en communication fluidique avec le passage de gaz pour distribuer un gaz vers l'orifice de sortie. L'ensemble de torche comprend en outre un filtre raccordé à l'embout à son extrémité proximale, le filtre étant disposé entre l'ensemble d'ouvertures et le passage de gaz pour limiter le retour de flamme dans la tête du chalumeau.
