ANTI-EXPLOSION PANEL WITH ADDITIONAL DAMPER Russian patent published in 2018 - IPC E04B1/92 

FIELD: protective devices.

SUBSTANCE: invention relates to protective devices used in explosive and radioactive facilities, such as easy detachable panels and roofs, blast guards and shields, pressure relief valves. Explosion proof panel with an additional damper contains metal armored frame with metal armored lining and lead filler, and in the end faces has four fixed support pipes, and in the explosive object cover, four supporting rods are rigidly fixed, which are telescopically inserted into the fixed support pipes of the panel and are provided with arranged in the upper part sheet stops, and by shape the filler is made in the form of crumbs of different diameters of spherical or arbitrary shape, wherein for fixing the panel limit position to the ends of the supporting elastic rods with stop sheets, a damping element is attached intended for the panel impact loads damping against the stop sheets, wherein it is attached oppositely to the panel and is directed towards it, and is made in the form of a volumetric body with an internal cavity and surfaces equidistant to the panel surfaces, at that, its internal cavity is filled with a disperse air-lead system, wherein the lead is made in the form of a crumbs with spherical shape, and between the attached oppositely to the panel damping element, and a metal frame with armored metal skin bushings from a rapidly disintegrating material, for example, glass of the "triplex" type, are installed on the support rods. To the damping element opposite to the panel, on the side of the metal frame, an additional damper is attached, made in the form of a conical element from elastic shell filled with polyurethane.

EFFECT: higher reliability of explosion-resistant device operation during emergency explosion at the facility, and ensured return of these device to the original position after explosion.
