PRESSURE VESSEL OVERPRESSURE VENTING BY THREAD STRIPPING OF CAPTIVE NUTS ON COVER BOLTS

摘要

A pressure vessel includes an enclosure adapted to contain a structural assembly in a pressurized environment. The vessel includes first and second enclosure components which together define the enclosure, the first enclosure component is movable relative to the second enclosure component which permits the enclosed pressure to be vented. Structure is provided for coupling between the first and second enclosure components, wherein the structure becomes inoperative when the pressure within the vessel reaches a predetermined excessive level thereby allowing the first enclosure component to separate from the second enclosure component. Structure for limiting the distance the first enclosure component may separate from the second enclosure component is also provided.
