Abstract

A flow-controlling unit provided in a flow channel is disclosed. The flow-controlling unit provided in a flow channel, according to one embodiment of the present invention, comprises: a plate which is disposed perpendicular to the moving direction of a fluid in a flow channel, and on which are formed multiple fluid through-holes through, which the fluid passes; and one or more flow-controlling pieces which are provided in a position corresponding to the fluid through-holes, form an inclination with respect to the plate in the direction of the inflow of the fluid, are capable of tilting on the plate, and control the degree of opening of the fluid through-holes by being tilted due to pressure applied from hydraulic pressure of the fluid.

Claims

1. A flow-controlling unit comprising:

a plate which is disposed to be perpendicular to a movement direction of a fluid in a flow channel, and on which one or more fluid through-holes through which the fluid passes are formed; and

one or more flow-controlling pieces, which are provided at a position corresponding to the fluid through-holes, form an inclination with the plate in the movement direction of an inflow of the fluid, are capable of tilting with respect to the plate, and control a degree of opening of the fluid through-holes by being tilted while being pressed by hydraulic pressure of the fluid,

wherein a bypass flow channel spaced from the one or more fluid through-holes and configured to prevent the flow of the fluid from being interrupted is formed in a center of the plate.

2. The flow-controlling unit of claim 1, wherein the one or more flow-controlling pieces form the one or more fluid through-holes, by being partially cut from the plate and bent to an inflow-side of the fluid to form the inclination with the plate.

3. The flow-controlling unit of claim 1, wherein the one or more fluid through-holes and the one or more flow-controlling pieces are formed, the fluid through-holes and the flow-controlling pieces are disposed on a concentric circle around a center of the plate.

4. The flow-control ling unit of claim 1, wherein the one or more flow-controlling pieces have an elastic force and a restoring force so that the one or more flow-controlling pieces can be restored to its original state when the hydraulic pressure is removed.

5. The flow-controlling unit of claim 1, wherein when the one or more fluid through-holes and the one or more flow-controlling pieces are formed, at least two of the one or more flow-controlling pieces are formed such that projected areas on which the hydraulic pressure acts are different from each other, and by being tilted while being pressed due to the hydraulic pressure of the fluid, the degrees of opening of the one or more fluid through-holes are sequentially narrowed in accordance with the areas of the one or more flow-controlling pieces.

6. The flow-controlling unit of claim 1, wherein when the the one or more fluid through-holes and the one or more flow-controlling pieces are formed, the inclinations of at least two of the one or more flow-controlling pieces with the plate are formed to be different from each other, and by being tilted while being pressed due to the hydraulic pressure of the fluid, the degrees of opening of the fluid through-holes are sequentially narrowed in accordance with the inclinations of the one or more flow-controlling pieces.

7. The flow-controlling unit of claim 1, wherein a dimension of-the one or more flow-controlling pieces corresponds to a dimension of the respective one or more fluid through-holes.
