Pressure relief panels and louvers |
摘要 |
A pressure relief panel assembly for buildings in which explosions may occur includes a panel pivotally coupled to a frame for movement between a normal closed position and an open position and a calibrated magnet and striker set for holding the panel in its closed position. The magnet has a maximum holding force substantially in excess of a known force to which it is subjected at a predetermined blow-out pressure and a striker has secured thereto at least one non-magnetic shim defining a face for contact with the magnet. The shim thickness is selected to reduce the effective holding force exerted on the striker by the magnet, to the said known force.
