Disclosed is a flow control unit. According to an embodiment of the present invention, the flow control unit comprises: a flow control plate; a closing prevention plate; and a back flow prevention plate. The flow control plate is arranged on a flow channel to be vertical to a flow direction of a fluid, has at least one first fluid through hole allowing fluid to pass therethrough, and has a flow amount control piece slanted in a flow induction direction to be tilted and controlling the degree of opening of the fluid through hole in such a manner where the flow control plate is pressurized by a fluid pressure of the fluid to be tiled. The closing prevention plate has a second flow through hole connected with the first flow through hole and secures a minimum angle between the flow control piece and the plate to prevent the flow control piece from becoming horizontal to the plate by the fluid pressure of the fluid to block the flow of the fluid. The back flow prevention plate has a third flow through hole formed thereon to be connected with the first flow through hole and the second flow through hole and is positioned to be in contact with the opposite side of the closing prevention part to prevent a back flow of the fluid. |
