When the pressure in the airlock chamber is equal to that in the outer space, open the outer gate to enter the space.When the astronauts return to the airlock, they operate in the reverse order: close the outer gate, pump the air in the cockpit into the airlock, and when the pressure of the two is equal, open the inner gate, and the astronauts can enter the cockpit.The absolute reliability of the air tightness of the inner and outer gates is the basic condition for the operation of the air lock chamber.

On July 4, 2021, Chinese astronauts must pass through the airlock before leaving the capsule for space walk.The airlock cabin generally has two doors (also called gates), one is the inner door connected with the manned cabin, and the other is the outer door that can lead to the space.[1]
On July 24, 2022, the Sky Quest experimental module set sail to build a dream palace. By August 24, it had been in orbit for a whole month.During this month, the crew of Shenzhou 14 astronauts first carried out necessary inspections and status settings for the "new home", confirmed that the cabin environment, equipment, etc. were in good condition, and the entry status settings took about two weeks.[2]
At 0:33 on September 2, 2022 (Beijing time), after about six hours of extravehicular activities, Shenzhou 14 astronauts Chen Dong, Liu Yang and Cai Xuzhe worked closely together to complete all the tasks set during extravehicular activities. Chen Dong and Liu Yang had safely returned to the Sky Quest Module, and the extravehicular activities were successful.
This is the first time for astronauts to exit from the air lock of the Sky Quest Experimental Module assisted by a small manipulator.During the astronauts' extravehicular activities, the space and sky worked together closely, both inside and outside the capsule, and completed the installation of the extended pump set of the capsule, the lifting of the panoramic camera of the capsule, and the verification of the extravehicular autonomous emergency return. The whole process was smooth and successful, and the ability of the astronauts to work together with the small robotic arm was tested,The functional performance of the air lock and the support equipment related to the extravehicular activities of the Sky Quest Experimental Module was verified.[3]
At 17:47 on September 17, 2022 (Beijing time), after about 5 hours of extravehicular activities, Shenzhou 14 astronauts Chen Dong, Liu Yang and Cai Xuzhe worked closely together to complete all the scheduled tasks during extravehicular activities. Astronauts Chen Dong and Cai Xuzhe returned safely to the Sky Quest Experimental Module, and the extravehicular activities were a complete success.During the astronauts' extravehicular activities, they successively completed the installation of the extravehicular power handle, the installation of the load circuit expansion pump set, the extravehicular rescue verification and other tasks, and the whole process was smooth and successful. They further inspected the ability of the astronauts to work together with the small robotic arm, and verified the functional performance of the air lock chamber of the sky inquiry experimental module and the support equipment related to the extravehicular activities.[4]
