ABSTRACT:
A pressure relief device for pneumatic conveying lines to serve as a safety device in the event of an explosion or sudden pressure increase within the conveying line. The device includes a pair of semi-cylindrical shells normally joined together by a shear pin or pressure sensitive key which ruptures when excessive pressure in the conveying line exerts excessive force on the shell sections. When the joining device ruptures, the shell sections open up to relieve line pressure. A suitable mounting arrangement is provided including guide bars for the shells, bumpers and spring return arrangement.
