Title:
ばね鋼製再閉パネルを備える高超過圧ベント構造
Document Type and Number:
Japanese Patent JP4796649
Kind Code:
B2
Abstract:
Apparatus for protecting a confined space having a vent aperture for relief of an overpressure condition and provided with a vent unit having a pressure relief portion normally closing the vent aperture is provided with recloser structure for generally closing off the vent aperture in the event of opening of the pressure relief portion of the vent unit. The recloser structure includes a resilient, flexible, spring steel recloser panel that is normally 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 mechanism for actuating the latter to release the recloser panel for movement as a function of its inherent resilience into substantially closing relationship to the vent aperture after the relief portion of the vent unit has opened. The vent apparatus including the spring steel recloser panel may be of either rectangular or circular configuration.
