Abstract

PURPOSE: To enable visually conformation for amatter which there is a trace for releasing pressure or not, by providing a lid to be removed on the pressure relief device, with a relief plate broken.
CONSTITUTION: A relief plate 8 is broken by sudden pressure rising in the sealed vessel with a knife 9, a dust-proof film 11 is broken by relieving flow at that time, and the lid is removed. Consequently, confirmation for amatter which there is a trace for releasing pressure or not can be carried out by dropping of the lid, simultaneously the dust-proof film can be protected from the checking for the device.
