The invention provides a system for circularly supplying gas to a sealed cabin body in a vacuum environment. The system comprises a high-pressure oxygen tank, a first pressure reducing valve, a high-pressure nitrogen tank, a second pressure reducing valve, a waste gas treatment unit, an air conditioning device and a first power unit, wherein the first pressure reducing valve is connected with thehigh-pressure oxygen tank, the second pressure reducing valve is connected with the high-pressure nitrogen tank, the waste gas treatment unit is used for treating waste gas in the sealed cabin body and outputting residual oxygen and nitrogen, the air conditioning device is connected with the first pressure reducing valve, the second pressure reducing valve and the waste gas treatment unit, the airconditioning device is used for conducting pressure and flow adjustment on the oxygen and nitrogen subjected to pressure adjustment and the remaining oxygen and nitrogen, and the first power unit isused for sending the oxygen and nitrogen subjected to pressure and flow adjustment to the sealed cabin body. By adopting the technical scheme, the technical problem that a gas compressor is small in pressurization ratio and cannot meet the requirement of application occasions with a large pressurization ratio in the prior art is solved.

    本发明提供了一种用于真空环境下密封舱体循环供气的系统,该系统包括高压氧气罐、第一减压阀、高压氮气罐、第二减压阀、废气处理单元、空气调节装置和第一动力单元,第一减压阀与高压氧气罐连接,第二减压阀与高压氮气罐连接,废气处理单元用于对密封舱体内的废气进行处理并输出剩余的氧气和氮气,空气调节装置分别与第一减压阀、第二减压阀以及废气处理单元连接,空气调节装置用于对调压后的氧气与氮气以及剩余的氧气和氮气进行压力和流量调节,第一动力单元用于将压力和流量调节后的氧气和氮气送至密封舱体。应用本发明的技术方案,以解决现有技术中压气机增压比较小无法满足增压比较大应用场合的技术问题。
