Description

Technical Field

[0001] The utility model belongs to the technical field of airtight door sealing, in particular to an airtight door sealing device. Background Art

[0002] At present, in biosafety laboratories, ordinary mechanical doors can no longer meet the requirements of biosafety levels. Biosafety laboratories require that the doors used must be able to withstand 1000PA positive pressure or -500PA pressure in the room, and viruses or gases cannot leak out. In hospitals, due to purification requirements for operating rooms and auxiliary rooms, the rooms need to be sealed to reduce air leakage and maintain a certain pressure gradient to meet purification requirements. Therefore, a biosafety advanced laboratory mechanical compression airtight door is needed for biosafety laboratories to achieve the purpose of isolating indoors from outdoors and preventing outdoor odors from entering the operating room.

[0003] When the airtight door is used, the sealing performance of the sealing strip is reduced after long-term use due to external factors. However, the existing sealing strip is adhered to the door by glue, which is not conducive to the staff to quickly remove and replace the sealing strip, thereby reducing the installation efficiency of the sealing strip.
