To provide a liquid supply system with a simple and compact configuration which can stably supply liquid of high temperature such as molten metal or molten salt with high corrosiveness, at comparatively small amount of a constant flow rate, without commingling of impurity and generation of blockage due to the impurity.
The liquid supply system includes: an impurity commingling preventing tube 14 which extends above from the upper end of a molten liquid drain pipe 12, covering the lateral circumference of the molten liquid drain pipe which can freely flow out molten liquid M accommodated in a liquid reservoir 10 below the liquid reservoir, and has a through-hole 14a that can freely introduce the molten liquid accommodated in the liquid reservoir to the molten liquid drain pipe side; and a weight 30 which can freely descend to be dipped inside the molten liquid accommodated in the liquid reservoir. The position of the upper edge of the through-hole is set lower than the lower limit of a liquid face of the molten liquid accommodated in the liquid reservoir. A variation of dipping volume of the weight, per unit time, which is dipped in, descending with respect to the molten liquid accommodated in the liquid reservoir, is constantly set, and the molten liquid accommodated in the liquid reservoir can freely flow out from the molten liquid drain pipe at a flow rate in accordance with the variation of the dipping volume.
