Reverse buckling rupture disc assembly with knuckle support structure
A patent application (Publication Number: US20240035582A1) discloses a rupture disc assembly designed to prevent overpressure in industrial equipment. The assembly includes an inlet body, an outlet body forming a throughbore with a rupture disc sealing it, and a knuckle designed to catch the rupture disc upon activation. The knuckle features a crown with a crown radius, curved wings, and a backside reducing from the inner diameter at a draft angle. The assembly can be configured with separate pieces or welded into a single unit, with specific ratios and angles determining the design elements.
Furthermore, the patent application describes variations in the rupture disc assembly, including different configurations for the inlet body, outlet body, and rupture disc. The knuckle design, with its crown radius, curved wings, and draft angle, is crucial in ensuring the proper functioning of the assembly. The crown radius is proportional to the inner diameter of the throughbore, and specific ratios and angles are maintained to optimize the performance of the assembly. Additionally, an asymmetric keyed extension in the outlet body is mentioned as part of another configuration, highlighting the versatility and adaptability of the design to different industrial settings.
