Instantaneous explosion proof armored fire door
The invention discloses an instantaneous explosion proof armored fire door. The door comprises a door frame arranged on a wall and a door body matched with the door frame. The door body and the door frame are sealed by a sealing mechanism. The door body comprises an outer shell facing outdoor space and an inner shell facing indoor space. The outer shell is detachably connected with the inner shell. A closed filling chamber is formed between the two shells. A plurality of air vents communicated with the filing chamber are formed in the outer shell. A thermal expansion layer and a filling layerare arranged in layers in the filling chamber. The thermal expansion layer is attached to the outer shell and covers the air vents. The thermal expansion layer generates local expansion deformation after being heated so as to tilt up and bend to release the air vents, and pushes the filling layer and the inner shell to be separated from the outer shell. The air vents are used to slowly release airinto the indoor space for low-oxygen combustion-supporting, so as to avoid instantaneous explosion due to sufficient oxygen supply.
本发明公开了一种防瞬爆装甲防火门，包括安装于墙壁的门框和与所述门框配合的门体；所述门体与门框之间通过密封机构密封；所述门体包括朝向室外的外侧壳体和朝向室内的内侧壳体，所述外侧壳体与内侧壳体可拆卸地连接，并在两壳体之间形成密闭的填充腔室；所述外侧壳体上开设有若干与填充腔室连通的通风口；所述填充腔室内分层设置有热膨胀层和填充层；所述热膨胀层贴附于外侧壳体设置并覆盖通风口；所述热膨胀层在受热后产生局部膨胀变形，使自身翘起弯曲释放通风口，并推挤填充层和内侧壳体脱离外侧壳体；通风口用于将空气缓慢释放入室内进行低氧状态的助燃，避免氧气供应充足而产生瞬爆。
