Abstract

A low-profile burst disk assembly for safely venting excess pressure from a pressurized fluid system by way of a tortuous fluid flow path. A burst disk plug includes a male thread and is thereby adapted to thread into the body of a pressurizable chamber. The burst disk plug further includes a fluid receiving port placed in fluid communication between the burst disk and one or more bleed channels open to ambient pressure. The one or more bleed channels generally run axially through the burst disk plug, either intersecting or bypassing the male thread. Embodiments with a plurality of bleed channels generally include a distribution manifold positioned in fluid communication between the fluid receiving port and the one or more bleed channels to ensure an even distribution of venting pressure among the bleed channels. A flange surface further deflects pressurized fluid as it escapes from the bleed channels toward the ambient environment, thereby dispersing the resulting thrust in multiple directions and minimizing the effective force exerted on the body of the pressurized fluid system.
