Pneumatic type closed smoke-blocking type safety fireproof door
The invention discloses a pneumatic type closed smoke-blocking type safety fireproof door, and belongs to the technical field of fireproof doors. According to the pneumatic type closed smoke-blocking type safety fireproof door, when a fire disaster occurs, a ball pricking steel needle can spontaneously prick a material storage balloon, a pneumatic solution flows out, pneumatic powder reacts to generate a large amount of carbon dioxide, the generated carbon dioxide flows into an arc-shaped guide cylinder through a communicating hole and can push the push rod piston, and therefore the fireproof door in an open state is closed, the fireproof door is ensured to be in a closed state when the fire disaster happens, then smoke is prevented from penetrating through the fireproof door and rushing to an escape channel, the safety performance is greatly improved, through the arrangement of an air leakage door opening assembly, escape personnel can make an air leakage main pipe communicated through a first valve and a second valve on the two sides of the fireproof door correspondingly, and therefore the carbon dioxide is sprayed out; and the sprayed carbon dioxide can achieve a flame-retardant effect, so that fire spreading is hindered to a certain extent, and more sufficient escape time is won for people.
本发明公开了一种气动式确闭阻烟型安全防火门，属于防火门技术领域。可以实现火灾发生时，刺球钢针可自发性的刺破储料气球，使气动溶液流出并气动粉剂反应生成大量二氧化碳，生成的二氧化碳经连通孔涌入弧形导向筒可顶动推杆活塞，从而关闭处于打开状态的防火门，确保火灾发生时防火门处于关闭状态，进而防止烟气穿过防火门涌向逃生通道，大大提高了安全性能，并通过泄气开门组件的设置，使得逃生人员可在防火门的两侧分别通过第一阀门、第二阀门使泄气主管导通，从而喷出二氧化碳，进而顺利打开防火门，且喷出的二氧化碳可起到一个阻燃效果，从而在一定程度上阻碍火势的蔓延，为人们赢得更充足的逃生时间。
