High-safety protective air-tight door structure for civil air defense engineering
The invention relates to the technical field of civil air defense doors, in particular to a high-safety civil air defense engineering protective airtight door structure which comprises a civil air defense door body, a ventilation cavity is formed in the civil air defense door body, and a ventilation device used for communicating two annular cavities with a ventilation pipe is jointly installed between the two annular cavities and the ventilation pipe. The bottom of the ventilation cavity is fixedly communicated with a first ventilation pipe, and the bottom of the first ventilation pipe is communicated with the ventilation pipe; a high-temperature communication device is mounted in the ventilation cavity, and when a fire disaster occurs at high temperature, the high-temperature communication device is used for enabling the ventilation cavity to communicate with the first ventilation pipe and the second ventilation pipe; according to the civil air defense door, through the arrangement of the high-temperature communicating device, carbon dioxide is sprayed out from the edge of the civil air defense door body when a fire disaster occurs at high temperature, the oxygen content in air is reduced through spraying of the carbon dioxide, and therefore the fire behavior can be prevented from spreading from the edge of the civil air defense door body, and the spreading speed of the fire behavior can be delayed.
本发明涉及人防门技术领域，尤其是一种高安全性的人防工程防护密闭门结构，包括人防门主体，所述人防门主体的内部开设有通气腔，两个所述环形腔与所述通气管之间共同安装有用于连通三者的通气装置，所述通气腔的底部固定连通有第一通气管，所述第一通气管的底部与所述通气管相连通；所述通气腔的内部安装有高温连通装置，在遇火灾高温时，所述高温连通装置用于使得所述通气腔连通所述第一通气管与所述第二通气管；此装置通过高温连通装置的设置，使得在遇到火灾高温时，在人防门主体的边缘处喷出二氧化碳，通过二氧化碳的喷出降低空气中的氧含量，从而有利于阻止火势由人防门主体的边缘处蔓延，从而有利于延缓火势的蔓延速度。
