FIELD: construction.SUBSTANCE: in a bench for testing of explosion-proof structures of buildings and facilities, a blast chamber is equipped with an easily dropped element installed in the end part of the vessel, closed with a safety screen, in parallel to a mechanical pressure indicator with a tumbler of indicator motor start. The blast chamber with a spark plug and a button to star ignition are arranged oppositely to the end part of the vessel, closed with a safety screen. The vessel is equipped with nozzles for blowing of the blast vessel, a nozzle for pouring of the flammable liquid is fixed in the vessel wall above contacts of the spark plug, elements that participate in testing: a pressure indicator, a spark plug, a nozzle for pouring of flammable liquid, a nozzle for blowing of the blast vessel is chosen by tensile strength exceeding the strength of the investigated easily discharged element. Blast pressure is recorded with a mechanical pressure indicator.EFFECT: increased efficiency of protection of buildings, structures and process equipment against explosions.2 cl, 4 dwg |
