Description
Technical Field
The utility model relates to a protective airtight door technical field specifically is a two-way atress protective airtight door.
Background
The protective airtight door can block shock waves and meet the corresponding resistance requirement. When the pressure-resistant steel pipe is selected for use, the requirement on the size of the hole opening is met, and the requirement on design pressure is met. Although the steel structure door is relatively high in price and relatively poor in early nuclear radiation prevention performance, the steel structure door is relatively light in self weight and flexible in opening and closing, and therefore the steel structure door is usually used for vehicle entrances and exits with relatively large sizes.
The strength of the door body of the existing bidirectional stress closed protective door on the market can meet most requirements generally, but the joint of the door body and the door frame is fragile generally.
