Multi-airtight door
The invention discloses a multi-airtight door. According to the multi-airtight door, an abutting ring table is arranged at the front end of a door frame, a first sealing strip is arranged on the abutting ring table, an annular concave table is arranged on the rear side of the door frame, an annular pressing plate extending towards the peripheral side of a door leaf is arranged on the back surfaceof the door leaf, a plurality of hinges connected to the back surface of the door frame are arranged on one side of the back surface of the door leaf, the annular pressing plate can be connected to the annular concave table in an abutting mode, a second sealing strip is arranged on the inner surface of the annular pressing plate or the surface of the annular concave table, the front surface of thedoor leaf can be connected to the first sealing strip in an abutting mode, so that when the door leaf is closed, two sealing systems are formed between the door leaf and the door frame through the first sealing strip and the second sealing strip. when the door leaf is closed, a negative pressure state is formed between the door leaf and the side wall of the door frame, so that the door leaf and the door frame are combined with the first sealing strip and the second sealing strip more tightly, the sealing effect is better, and therefore the air tightness of the door can be kept under the condition that an air pressure valve is not needed.
本发明公开了一种多重气密门，通过在门框的前端设置一抵接环台，抵接环台上设置有第一密封条，在门框后侧设置有环形凹台，在门扇背面设置有一朝向门扇周侧延伸的环形压板，门扇背面的一侧设置有与门框背面相连的若干合页，环形压板可与所述环形凹台抵接，所述环形压板内表面或环形凹台表面设置有第二密封条，门扇正面可与所述第一密封条抵接，从而在关闭门扇时，门扇与门框之间会通过第一密封条和第二密封条形成两道密封体系，门扇在关闭时使门扇与门框侧壁之间形成负压状态，使门扇以及门框与第一密封条和第二密封条的结合更为紧密，使密封效果更好，从而在不需要使用气压阀的情况下也能保持门的气密性。
