Poison gas sealing door for civil air defense engineering
A poison gas sealing door for civil air defense engineering comprises a civil air defense wall body, a door opening formed in the civil air defense wall body and a sliding door used for opening and closing the door opening, an exhaust fan is arranged on the closed side edge of the sliding door, and a fan shaft of the exhaust fan is in transmission connection with a main shaft through a middle transmission shaft. And when the hand wheel is rotated to close the sliding door, the exhaust fan exhausts gas on the inner side of the sliding door to the outer side of the sliding door. The device is used for reducing the amount of poison gas possibly entering the air-tight door in the closing process, and personnel safety is guaranteed.
一种人防工程用毒气密闭门，包括人防墙体、开设在人防墙体上的门洞以及用于开闭门洞的推拉门，推拉门的闭合侧沿设有抽气扇，且抽气扇的风扇轴通过中间传动轴与主轴传动连接，以使抽气扇在转动手轮以关闭推拉门时将推拉门内侧气体排至推拉门外侧。本发明用于减少密闭门关闭过程中可能进入的毒气量，保障人员安全。
