HIGH OVERPRESSURE VENT STRUCTURE HAVING SPRING STEEL RECLOSER PANEL

摘要

Apparatus for protecting a confined space having a vent aperture for reli ef of an overpressure condition and provided with a vent unit having a press ure relief portion normally closing the vent aperture is provided with reclo ser structure for generally closing off the vent aperture in the event of op ening of the pressure relief portion of the vent unit. The recloser structur e includes a resilient, flexible, spring steel recloser panel that is normal ly held in a bent condition out of closing relationship to the vent aperture . Releasable mechanism engages the recloser panel for normally retaining the panel in its open position. An actuator is connected to the releasable mech anism for actuating the latter to release the recloser panel for movement as a function of its inherent resilience into substantially closing relationsh ip to the vent aperture after the relief portion of the vent unit has opened .
