Sodium-fire-proof airtight door fireproof sealing structure
The fireproof sealing structure comprises a three-layer step structure of a door leaf and a door frame, metal sealing pieces arranged on a first-layer step and a third-layer step of the door frame, thermal expansion rubber sealing strips arranged on the side faces of the two steps of the door leaf, and an annular sealing piece arranged on the middle step of the door leaf. Under the pressing of thelocking device, the fireproof sealing performance of the joint of the door leaf and the door frame of the sodium fire prevention airtight door in a sodium fire accident is guaranteed.
本发明公开了一种防钠火气密门防火密封结构，包括门扇和门框的三层台阶结构，布置于门框第一和第三层台阶的金属密封件、布置于门扇两台阶侧面的热膨胀橡胶密封条、布置于门扇中间台阶的环形密封件。本发明在锁紧装置的压紧下，保证防钠火气密门在钠火事故中的门扇与门框接缝处的防火密封性能。
