High pressure gas propelling system used for microsatellite

The utility model relates to a high pressure gas propelling system used for a microsatellite. Through the high pressure gas propelling system used for the microsatellite, high gas storage capacity can be achieved, thrust provided by the system can be adjusted according to needs, and meanwhile the system is simple in structure. The system comprises a high pressure gas storage cylinder, a high pressure self-locking cylinder valve, an electronic pressure regulating valve and a spout electromagnetic valve, wherein the high pressure gas storage cylinder is provided with a spherical aluminum alloy liner, and carbon fibers are wound around the aluminum alloy liner; the high pressure self-locking cylinder valve is installed at the opening of the high pressure gas storage cylinder and used for controlling inflow and outflow of gas in the high pressure gas storage cylinder; the electronic pressure regulating valve is installed on a pipeline at the rear end of the high pressure self-locking cylinder valve and used for regulating pressure of gas at an outlet; the spout electromagnetic valve is installed at the outlet of the pipeline and used for spraying the gas at the outlet at a high speed, so that the thrust is provided for the whole microsatellite.
