Disclosed herein are a valve and a micro fluid pump having the same. The valve is mounted in a micro fluid pump having a capillary tube, to which a gas supply unit and a fluid transfer pipe are connected, for controlling the introduction and the discharge of fluid. The valve includes a discharge pipe filled with liquid such that the discharge pipe has a predetermined resistance pressure and constructed in a structure in which one end of the discharge pipe is connected to the capillary tube such that the discharge pipe communicates with the interior of the capillary tube, and the other end of the discharge pipe is open, thereby allowing gas out of the capillary tube through the discharge pipe when a gas pressure in the capillary tube exceeds the resistance pressure of the discharge pipe.

Disclosed is a self-reciprocating energy recovery device utilized in driving of a seawater pump by self-reciprocating a piston of a power recovery chamber and recovering energy not using an electronic drive unit but using the hydraulic power of concentrated water. The self-reciprocating energy recovery device including a pair of power recovery chambers having pistons therein respectively, a high-pressure concentrated supply pipe, a low-pressure concentrated discharge pipe, and a high-pressure seawater discharge pipe to enable the power recovery chambers to recover hydraulic power supplied through the high-pressure concentrated water supply pipe and utilize the hydraulic power in driving of a seawater pump.
