Flow path control valve and fluid control device

Abstract

The utility model relates to fluid control technical field especially relates to a flow path control valve and fluid control device, including the support plate, the flow guide plate, the frame board and the bottom plate that form the overall structure in turn layering together along the thickness direction, the frame board has the opening part, still include the valve plate, the valve plate has the deformation part and the junction part that connect, the valve plate is fixed in the bottom plate through the junction part, and the outer peripheral edge of deformation part exists a part as the free area, and the deformation part can produce the elastic deformation under the pressure effect, the utility model discloses flow path control valve is advantageous to further promote the thin degree of the air leakage valve on one hand, the other hand makes the overflow passage formed after the deformation of deformation part not depending on the hole structure of deformation part can realize the communication of inlet hole and flow guide hole, and therefore deformation part can realize maintaining the overall structure, can better inhibit the risk that deformation part appears the deformation even the cracking because of setting the hole structure, ensure the stability and reliability of control valve work, improve the service life.
