A fluid control throttle valve includes a first tube and a second tube, both of which have an inner passage respectively. Between the first and second tubes are disposed an adjusting element and a cylindrical communicating element, wherein the adjusting element has a central axis and a plurality of throttling orifices axially disposed therein. The distance between the central axis and the throttling orifices, respectively, is substantially the same with each other, while the throttling orifices are arranged radially around the central axis of the adjusting element, wherein a bore diameter of at least one throttling orifice is different from that of the other throttling orifices. In addition, the communicating element has a through hole axially disposed therein. The communicating element is axially rotatable with respect to the central axis of the adjusting element, wherein the through hole thereof selectively communicates a selected throttling orifice.
