Abstract:
A valve and a micro fluid pump having the same are provided to prevent a capillary from being damaged or erroneously operated by preventing a transfer pipe from being pressed over a predetermined pressure. A valve includes a capillary(1), an outlet pipe(21) and a valve(2). The capillary is connected to a fluid transfer pipe and an air providing unit. The valve is installed on a minute liquid pump, and adjusts an inflow and an outflow of a fluid. The outlet pipe is connected to a side of the capillary to be coupled to the inside of the capillary. A liquid is filled in the outlet pipe to have a uniform resistance pressure. An ejection unit is formed on an upper part of a side of the outlet pipe. If the air pressure inside of the capillary is above a predetermined pressure, until the inner pressure of the capillary is stabilized, the valve exhausts gas in the capillary into the outside in a bubble state through the liquid of the outlet pipe, and stabilizes the inner pressure.
