Metal door with fire prevention and heat insulation functions
The invention discloses a metal door with fire prevention and heat insulation functions. The metal door comprises a door frame; a groove is arranged in the door frame; a cavity is arranged in a door body; an elastic hose is fixed to the inner wall of the groove; a first fireproof packet is fixed onto the side wall of the elastic hose, and a second fireproof packet is arranged in the cavity, so that effects of fire resistance, flame retardancy and heat insulation are exerted; when a smoke transducer detects that a density value reaches a preset value, a gas pump can be triggered so as to make smoke pass through a wind inlet scoop, the elastic hose and a one-way valve in sequence and is pumped out by the gas pump; meanwhile, high-temperature gas can make the elastic hose expanded so as to push the first fireproof packet so as to seal a gap between the door frame and the door body by filling so as to comprehensively cut off fire spreading and smoke diffusion; meanwhile, heat of the door frame and the door body is absorbed by the first fireproof packet and the second fireproof packet so as to delay the time of deformation of the metal door at high temperature; and due to the elastic expansion feature of the elastic hose, normal opening and closing of the metal door is not influenced so as to be conducive to escaping or rescue in a fire accident.
本发明公开了一种具有防火隔热功能的金属门，包括门框，门框内设有凹槽，门体内部设有空腔，凹槽内壁上固定有弹性软管，弹性软管侧壁上固定有第一防火包，空腔内设有第二防火包，起到耐火、阻燃、隔热的效果，通过烟雾传感器检测到浓度值达到预设值时，可触发气泵，以使烟雾可依次通过进风斗、弹性软管、单向阀被气泵抽走，同时高温气体可使弹性软管膨胀以推动第一防火包，以填充封闭门框和门体之间的缝隙，以达到全面阻隔火势蔓延和烟雾扩散，同时，通过第一防火包和第二防火包对门框和门体吸热，以延缓金属门高温下形变的时间，且由于弹性软管可弹性伸缩的特点，从而不影响金属门的正常启闭，以利于火灾事故中逃生或施救。
