Because of large scale and heavy weight, end closures of high pressure vessels are usually hard to assemble and disassemble. In this paper, a new quick-opening seal device connected by D-shaped shearing bolts is introduced. This device is compact in structure, reliable in sealing, easy in assembly and disassembly, and very appropriate for end closures of pressure vessels or for pipe joints. Strength calculation formulas for the major parts are proposed analytically, and stress analysis using the finite element method for a C-ring seal has been performed. An application of this device shows that its sealing and strength is reliable.
