Civil air defense equipment is built to be a proposed building and structure in response to air raids by hostile countries, to reduce the loss of life and property of citizens and the harm to economic resources. At present, the civil air defense gate is the entrance and exit of the civil air defense project, and it is also an important part of the national defense project. Today, the producers of civil air defense doors and what points we need to pay attention to. The civil air defense door is the door of the entrance and exit of the civil protection project. The classification of civil air defense doors is relatively distinct, including ordinary single door and double door protection closed door, closed door, live, double door protection airtight door, airtight door and other civil air defense equipment. Civil air defense doors are divided by material: steel structure and concrete structure, and by threshold: fixed threshold and movable threshold. In addition, a closed partition wall, a closed observation window and an anti-virus passage should be set between the control room and the generator room of the civil air defense fixed power station, the wall opening should be provided with an air-protected sealing steel plate, and the vent should be equipped with an explosion-proof ventilation door.

10 key points for the installation and construction of civil air defense doors:

1. The specifications of the civil air defense door are expressed by the net width and net height of the door opening.

2. The opening and closing are normal and do not affect the evacuation width.

3. After closing, it is tight, no air leakage, no light leakage.

4. The live threshold is installed as an integral part of the door frame, which can be poured after the door and cannot be disassembled before acceptance.

5. The parts of the door leaf are complete, no rust and no damage.

6. Nameplate posting specifications and content specifications.

7. The opening and closing force conforms to the specification.

8. There is no self-opening and self-closing phenomenon.
