Humidifying flame-retardant fireproof door
The invention relates to the field of fire safety, in particular to a humidifying flame-retardant fireproof door which comprises a door body, a water spraying control mechanism, a flame-retardant mechanism and a locking mechanism, when a fire occurs near the door body, the flame-retardant mechanism is heated to transfer heat to expandable graphite in a storage box, the expandable graphite is heated to expand and is quickly decomposed to generate a large amount of gas, a piston plate is expanded by expandable graphite at the bottom of the piston plate to move upwards to drive the water spraying control mechanism, so that the valve plate does not seal the water spraying pipe any more, water at the top of the piston plate is extruded by the piston plate to pass through the water spraying pipe and is sprayed out of a spray head, sprayed water mist can slow down fire spreading near the fireproof door, meanwhile, the door body is cooled, the flame-retardant effect is improved, the graphite which is expanded to a certain degree in the storage box is sprayed out of a material spraying pipe, the expandable graphite is rapidly expanded, part of flames are suffocated, the surface of combustible materials near the door body is covered with the generated expanded graphite material, and contact between heat energy radiation and oxygen is isolated.
本发明涉及消防安全领域，具体的说是一种湿化阻燃防火门，包括门体、喷水控制机构、阻燃机构和锁定机构，当门体附近发生火情时，阻燃机构受热将热量传递给储存盒内的可膨胀石墨，可膨胀石墨受热膨胀并迅速分解，产生大量气体，活塞板受到其底部的可膨胀石墨膨胀向上移动带动喷水控制机构使阀板不再密封喷水管，活塞板顶部的水受到活塞板的挤压经过喷水管并从喷头喷出，喷出的水雾可以减缓防火门附近的火势蔓延，同时对门体进行降温，提升了阻燃效果，储存盒内已发生一定膨胀的石墨从喷料管喷出可膨胀石墨急剧膨胀，窒息部分火焰，其生成的石墨膨体材料覆盖在门体附近可燃物的表面，隔绝了热能辐射和氧的接触。
