ABSTRACT:
A pressure release mechanism for a heating apparatus using saturated vapor of a heating medium according to this invention will completely prevent undesirable intrusion of the air into a heating chamber even when the pressure within the chamber reduces down below the atmospheric pressure either during operation or out of operation of the heating apparatus, and also enables an easy replacement of the rupture plate when required.
The mechanism comprises a pair of metal pipes, each having a flange at one end thereof, a plate holder disposed to either one of said two flanges, a rupture plate welded onto said plate holder, fastening means which secure said pair of flanges with each other, and a seal cover extending over and between said pair of flanges and welded thereto so as to cover said fixture portion in an air tight manner.
