The invention relates to a microgravity fluid management device in the field of satellite space navigation. The microgravity fluid management device comprises a base, a net type surface tension management assembly and a gas-liquid phase management cavity; the gas-liquid phase management cavity comprises a gas-liquid two-phase storage cavity, an outer management cavity and an inner management cavity, and the outer management cavity communicates with the base and discharges liquid and adding gas-liquid phase fluid through the base; the net type surface tension management assembly comprises a gas window net piece, a middle-layer net piece and an outer-layer net piece; a bubble breaking point of the gas window net piece is smaller than that of the middle-layer net piece and that of the outer-layer net piece; the gas-liquid two-phase storage cavity communicates with the outer management cavity through the gas window net piece; the outer management cavity communicates with the inner management cavity through the middle-layer net piece; the inner management cavity communicates with the gas-liquid two-phase storage cavity through the outer-layer net piece. The microgravity fluid management device effectively solves the problem that an existing microgravity fluid management device cannot achieve pure liquid phase supply and gas-liquid phase filling functions at the same time through a single connector.
