KOCHETOV ANTI-EXPLOSION PANEL WITH SECURITY INDICATOR Russian patent published in 2017 - IPC E04B1/92 

FIELD: fire-prevention facilities.

SUBSTANCE: invention relates to protective devices used in hazardous and radioactive facilities, such as easily resettable panels and roofs, explosion-proof enclosures and dampers, overpressure valves. The explosion-proof panel comprises a metal armoured frame with metal armoured plating and lead filling, and has four fixed bearing pipes at the butts. In the explosive object coating four support rods are tightly sealed, which are telescopically inserted in the fixed bearing pipes of the panel. The filler is made in the form of dispersed air-lead system, wherein the lead is shaped in the form of crumbs. Outside the support rods elastic-damping elements are arranged, one end of which rests on the metal armoured plating and the other one - in the sheet-stops disposed at the top of the support rods. The elastic-damping elements are made in the form of cylindric helical springs, the outer helical surface of which is covered with vibration-damping mastic, for example of HP-17 type.

EFFECT: invention allows to improve the reliability of operation of explosion-proof devices in case of accident explosion at the facility, and to ensure their return to the starting position after the explosion.
