Beschreibung
Zusammenfassung:	The invention discloses a micro-flow control system. The micro-flow control system comprises a first low-pressure self-locking valve, a second low-pressure self-locking valve, a first flow control electromagnetic valve, a second flow control electromagnetic valve, a first flow control valve, a second flow control valve, a third flow control valve, a fourth flow control valve, a fifth flow control valve and a control unit. In the micro-flow control system, energy of fluid is mainly reduced in the mode that the fluid flows through a quite complex channel in a labyrinth-like channel, and the flow is mainly adjusted by changing physical parameters of the fluid. By means of the micro-flow control system, the defects in the prior art are overcome, and the problems that a current-use satellite propelling system is large in medium supply flow and low in accuracy are solved.
