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-fibre material.
Dispositif (1) pour compenser des chocs de pression lors d'éventuelles explosions de poussière ou de gaz dans des systèmes fermés, comme des silos, des tuyauteries ou analogues, avec un couvercle rabattable (3) pouvant pivoter sur un piquage d'évacuation ou sur un châssis (2) et présentant une surface extérieure plane (12). Une plaque déflectrice (8) est prévue sur le piquage d'évacuation ou sur le châssis (2) pour venir buter contre le couvercle (3) en cas d'explosion. L'invention vise notamment, outre une fabrication économique, une nette diminution du poids du couvercle rabattable, un remplacement rapide du couvercle en cas de détérioration ou encore un premier montage rapide, et une amélioration de l'action protectrice du système. A cet effet, le couvercle rabattable (3) est constitué d'un matériau en fibres de verre et de carbone.
