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
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.

1. A device for equalizing pressure surges in the event of possible dust or gas explosions in closed systems, including silos and pipelines, comprising: a hinged lid having a body and a planar surface that can pivot;an outlet connector;a deflecting plate for contact of the lid in the event of an explosion on the outlet connector,wherein the hinged lid is formed from a carbon/glass fiber material, whereby the lid body is formed from carbon/glass fiber mats that form outer walls, with an enclosed body made of plastic foam material, forming the lid contour;wherein a heat tape is laminated into a side of the layer of carbon/glass fiber mat that faces outward and wherein said heat tape is configured to serve to prevent said hinged lid from freezing if temperatures fall below a freezing point; andwherein said deflecting plate is spring loaded and held in a transport position by means of multiple safety wires that are stepped in length. 2. The device according to claim 1, wherein the enclosed plastic body is configured approximately as a sphere segment. 3. The device according to claim 1, wherein a plurality of carbon fiber rovings is provided between the carbon/glass fiber mats that form outer walls of lid, to form a support structure. 4. The device according to claim 3, wherein the rovings are positioned in the plastic body and pass through the plastic body, whereby the rovings are cast in with synthetic resin. 5. The device according to claim 1, wherein the carbon/glass fiber mats are provided with aligned bores in a position of use, through which carbon fiber rovings pass. 6. The device according to claim 1, wherein the carbon/glass fiber lid is configured essentially in a circular shape, whereby the lid is positioned in a pivot frame composed of carbon and glass fiber mats, wherein a foam material ring and/or a reinforcement ring, as a rectangular plastic hollow profile, is positioned between the main lid body and the pivot frame. 7. The device according to claim 1, wherein at least the lid surface is provided with a coating. 8. The device according to claim 1, wherein a flame barrier body provided with a plurality of passage bores and structured as a honeycomb is positioned in the outlet connector. 9. The device according to claim 1, wherein a flame barrier cage is positioned around a case having a lid, and wherein the flame barrier cage is formed from a support framework covered by a woven flame barrier fabric. 10. The device according to claim 1, wherein the outlet connector, in a form of a case that carries the lid has a pressure-resistant bandage closure for quick installation. 11. The device according to claim 10, wherein the bandage closure is formed from at least one steel strip having at least one quick closure, whereby a plurality of clamping claws, having an approximately U shape in cross-section, particularly composed of a plastic material that can withstand great stress, is positioned on the steel strip, spaced apart from one another.
