Abstract
A flow control valve for a gardening pipe includes a main body, a control member, a rotation knob, and a bottom cap. Thus, the flow control valve has a simplified construction and is made easily, thereby decreasing costs of fabrication. In addition, the water flow rate of the flow control valve is controlled exactly by provision of the water outlet holes having different sizes, thereby facilitating a user operating and controlling the water output the flow control valve.
