The invention discloses a manual exhaust sealing cover device for emergency of a manned spacecraft, and belongs to the field of pressure control and pressure relief in cabins of manned spacecrafts. The device comprises a sealing cover, a wrench, a sealing valve body, a reed and a pin. The sealing cover is hinged to the sealing valve body through a pin, hot-pressing rubber is arranged on the lower surface of the sealing cover, and a sealing ring is arranged on the upper surface of the sealing valve body and matched with the hot-pressing rubber. The two wrenches are connected to the two sides of the sealing cover through pins, and the reeds are fixed to the inner sides of the wrenches. Under the non-emergency condition, the sealing cover is pressed after the two wrenches buckle the sealing valve body, the hot-pressing rubber is pressed on the sealing ring, and the reed provides sealing force. In emergency, an astronaut opens the wrench firstly when wearing clothes, then the sealing cover is lifted up for pressure relief, and it is guaranteed that the astronaut goes out of a cabin smoothly.

    本发明公开了一种载人航天器应急用手动排气的密封盖装置,属于载人航天器中舱内压力控制及泄压领域。该装置包括密封盖,扳手,密封阀体,簧片,销钉。密封盖与密封阀体通过销钉铰接,密封盖下表面设有热压橡胶,密封阀体上表面设有密封环,密封环与热压橡胶配合。两个扳手通过销钉连接在所述密封盖两侧,簧片固定在扳手内侧。非应急情况下,密封盖在两个扳手扣住密封阀体后被压紧,热压橡胶被压在密封环上,簧片提供密封力。应急情况下,航天员着服先打开扳手,再掀起密封盖进行泄压,确保航天员出舱任务的顺利进行。
