Paper presented at the 5th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 1-4 July, 2007.
Application and design of a new quick-opening seal
device connected by D-shape shearing bolts in hypersonic
wind tunnel is introduced in this paper. This device is
compact in structure, reliable in sealing, easy in assembly
and disassembly, appropriate for end closure of pressure
vessels or joints of pipes. Mechanical models are
established for all major components, and strength
calculation formulas are obtained which can be used for the
design of the structure.
