ABSTRACT:
A water flow regulating device which comprises a casing having a control chamber at the upper middle for holding a regulating valve and a division wall at the lower middle to block up the water outlet from the water inlet thereof. A teflon washer is set inside the control chamber and squeezed by the regulating valve, which has two through-holes disposed in alignment with the two through-holes on the bottom of the control chamber respectively in communication with the water inlet and the water outlet. The regulating valve is secured to the casing by a lock nut and is confined by a control ring to rotate on the teflon washer within a fixed range for controlling the alignment of its two through-holes with the through-holes on the teflon washer and the through-holes on the control chamber so as to regulate water flow rate from the water inlet into the water outlet. A clearance is maintained between the outer projection of a control ring and the bottom edge of the notch on the top edge of the control chamber so that the regulating valve can be further squeezed downward by the lock nut according to the wearing of the teflon washer in service.
