Device for equalizing pressure surges in closed systems, such as silos or the like

Abstract

With a device (1) for equalizing pressure surges in cases of possible dust or gas explosions in closed systems, such as silos, pipelines or the like, comprising a hinged cover (3) which can be pivoted on an outlet connection or a closing edge (2) and has a smooth outer surface (12) and comprising a deflecting plate (8) on the outlet connection or on the closing edge (2) for the cover (3) to strike against in the event of an explosion, it is intended to achieve not only cost-effective production but also in particular a significant weight saving of the hinged cover, quick changing of the cover in the case of damage, or quick fitting of the cover in the first instance, and an improvement in the protective effect of the system. This is achieved by the hinged cover (3) being made of a carbon/glass-fiber material, whereby the main lid body (3a) is formed from carbon/glass fiber mats (18, 19) that form the outer walls (12, 13), with an enclosed body (14) made of plastic, such as foam material, for example, forming the lid contour.
