More Information
Summary:A rupture disc (10) is provided comprising a line of opening (16) formed in at least one face thereof. The line of opening (16) is formed by laser machining of the disc's face and includes at least one disc opening control feature (20). The disc opening control feature (20) may be an opening-initiation feature configured to assist with initial rupture of the disc (10). Alternatively, the opening control feature (20) may be an anti-fragmentation feature configured to dissipate the energy acting upon the disc (10) so as to prevent separation of the petal formed upon opening of the disc. La présente invention concerne un disque de rupture (10) comprenant une ligne d'ouverture (16) formée sur au moins l'une de ses faces. La ligne d'ouverture (16) est formée par usinage laser de la face du disque et comprend au moins un élément (20) de commande d'ouverture de disque. L'élément (20) de commande d'ouverture de disque peut être un élément d'initiation d'ouverture conçu pour aider à la rupture initiale du disque (10). En variante, l'élément (20) de commande d'ouverture peut être un élément anti-fragmentation conçu pour dissiper l'énergie agissant sur le disque (10) de sorte à éviter une séparation du pétale formé lors de l'ouverture du disque.
