A water control structure for a spout of faucets comprising a water control valve assembly fastened to the spout of a faucet body through a fastening sleeve which is coupled by a rotary outer cap from outside to control opening and closing of water flow, wherein:
- the spout has an external screw thread and a water passage located inside to house a cold water duct and a hot water duct;
- the water control valve assembly includes:
- a valve seat being a hollow barrel and having an internal screw thread on one end, two flutes on an inner wall, and a flange located proximate to a middle portion thereof;
- a spindle housed in the valve seat having a head of a larger diameter on a upper side and a spline section on a lower side, and a through hole in the center, the head being latched on the flange of the valve seat and having two bosses on the upper side;
- a ceramic movable plate located in the valve seat having an arched water outlet and two notches on two sides of the bottom to couple with the bosses of the spindle;
- a ceramic anchor plate located in the valve seat having a bottom surface abutting a upper side of the ceramic movable plate and two water intake ports mating the water outlet of the ceramic movable plate to form a ceramic control valve to control water flow, and two ridges on a lateral side to couple with the flutes of the valve seat for anchoring;
- a coupling member located in the valve seat above the ceramic anchor plate having two ribs on a lateral side to couple with the flutes of the valve seat, and two coupling holes to couple with the cold water duct and the hot water duct;
- and
- a fastening lid being hollow and having an external screw thread to couple with a upper side of the valve seat to hold the elements set forth in the valve seat;
- wherein the fastening sleeve is hollow and has an internal screw thread on one end to engage with the external screw thread of the spout;
