[0001] The present invention relates to the field of aerostats and, more particularly, to a valve assembly for an aerostat and an aerostat.

Background technique

[0002] Aerostats generally refer to soft-structured aircraft that are lighter than air and that rely on atmospheric buoyancy to lift off. The aerostat consists of a capsule made of a polymer composite material and various devices and payloads placed on the capsule body. The capsule body is filled with a floating gas having a density lower than that of air, and the density difference between the gas inside and outside the capsule is provided. The buoyancy of the aerostats completes the aerostat lift. In the prior art, gas is usually discharged through an exhaust valve to maintain a pressure difference inside and outside the air bag.
