Relief device for a vacuum vessel
Abstract
A pressure relief device for a vessel having redundant pressure relief capabilities is disclosed. An annular plate overlies a surface which has an aperture to the vessel. A seal is formed between the surface and annular plate. A solid plate overlies the annular plate. A seal is formed between the solid plate and annular plate. The relief device will open at a first predetermined pressure by lifting the solid plate. In the event the seal between solid plate and annular plate should stick the relief device will open at a second slightly higher, predetermined pressure by lifting the annular plate and solid plate together. Hinging means are provided to reclose the pressure relief device when conditions return to normal. 2 figs.
