High-pressure high-temperature hot steam protection performance test device for fire protection equipment

Abstract

The invention discloses a fire-fighting protection equipment high-pressure high-temperature hot steam protection performance test device comprising a control display system, a test system and a simulating heat source part; the test system includes a shielding plate, the shielding plate is arranged at an opening of a specimen support plate, an air baffle plate is arranged above the specimen support plate, a heat gauge fixing plate is arranged above the air baffle, the heat gauge fixing plate is provided with a heat gauge, the heat gauge is connected with the test system, and a limit switch is arranged below the shielding plate. A hot steam source in the condition of simulation of a fire is used as a hot danger source, the high-temperature hot steam protection performance of fire clothing in the presence of hot steam, can be tested, the protection ability of a piece of the fire clothing can be comprehensively evaluated, the test database of various performance of the fire clothing can be completed, and the fire-fighting protection equipment high-pressure high-temperature hot steam protection performance test device has extremely vital significance to research and development of new fire clothing materials, and hot wet ergonomic design of the fire protection clothing equipment.

Description

technical field [0001] The invention belongs to the field of fire safety protection, and in particular relates to a test device for testing the heat resistance performance of firefighter protective equipment. Background technique [0002] Firefighting clothing and equipment are safety protective equipment for firefighters. They are mainly used to reduce the accumulation of heat on the human skin, thereby protecting the skin from burns or burns. Therefore, protective clothing requires not only good flame retardancy, but also high heat insulation performance. In actual firefighting, human skin may be exposed to the following thermal hazards: flame (convective heat); contact heat; radiant heat; sparks and molten metal droplets; high pressure heat and steam. Therefore, the above-mentioned risk factors for the protection of firefighters have received more attention and research. Standard organizations at home and abroad have successively formulated or issued relevant test standa...
