FIELD: protective devices.
SUBSTANCE: invention relates to protective devices used at explosive and radioactive facilities, such as easy detachable panels and roofs, blast resistant fences and gates, pressure relief valves. Explosion proof panel with emergency warning system comprises metallic armored frame with metal armored skin and lead filler, has four fixed supporting branch pipes at the ends. In the explosive object coating, four support rods are rigidly embedded, which are telescopically inserted into the panel fixed support branch pipes. Filler is made in form of air-lead disperse system, wherein the lead is made in the form of crumbs. Supporting rods are made flexible, at that, to the supporting rods ends from the side, facing the metal frame, dampening the shock wave impact additional elements are attached. Between the additional elements and the metal frame with armored metal lining on the supporting rods bushings of rapidly disintegrating material, for example, of the “triplex” type glass, are installed. Emergency warning system with safety indicator consists of the “weak link” fastener assembly in the explosive facility safety system, responding to emergency situation occurrence, made, for example, in form of attached between flanges safety indicator, which are rigidly fixed on blast panel metal frame armored metal plating upper part, and in the explosive object cover upper part near the opening, designed to relieve excess pressure. Safety indicator consists of sensor responding to deformation, for example, strain gage, which output is connected to the signal amplifier, for example, strain gage amplifier, and the strain gage amplifier output is connected to the emergency notification system input. Safety indicator flanges are tightened by the stud with upper and lower shanks with coaxially arranged with it cylindrical transparent casing, for example, from plexiglass. Through the washer and nut the stud shank upper and lower threaded ends interact with the flanges. Safety indicator is fixed on the side elastic ball surface with slots, located between the stud shanks and rigidly connected to them, or the safety indicator is fixed on the ellipsoid side elastic surface with slots, located between the stud shanks and rigidly connected to them, at that, in the casing provision is made for a window for the warning system with safety indicator preventive visual inspection.
EFFECT: invention allows to increase explosion-proof devices operation reliability during emergency explosion at facility and provide these structures return into initial position after the explosion.
