FIELD: security systems.SUBSTANCE: invention relates to safety systems in emergency situations and can be used for explosion protection of buildings and structures, as well as of process equipment. Test bench includes an explosion chamber, in the upper base of which there is a hole covered with an easy-to-discard element, herewith the square of the hole can be varied by screwing in replaceable rings, and the easy-to-discard element covers the hole in the ring, above which a protective screen is fixed, herewith the second hole is covered by a valve, which is pressed to the hole with the help of an electromagnet and is opened by a spring at opening contacts, and the force of the valve and the spring compression is set so, that their total force is equal to the tolerable pressure multiplied by the square of the valve hole, herewith the easy-to-discard element comprises a metal armored frame with a metal armored plating and lead as a filler with its ends four fixed branch pipes - supports, in the coating of the explosive object there are rigidly embedded four bearing rods telescopically inserted into fixed branch pipes - panel supports, herewith the filler is made as an air-lead disperse system, wherein lead is in the form of frit, the bearing rods are flexible, characterized by that between the additional elements and the metal frame with the armored metal plating on the bearing rods there are bushings from an easily destructible material, for example glass of triplex type.EFFECT: higher protection efficiency of buildings and structures, and also process equipment against explosions.1 cl, 3 dwg |
