Abstract:
1. A water control valve, which is configured to control a temperature of water by mixing hot and cold water and to control a flow rate of the hot water, cold water or a mix of the hot and cold water, comprising a valve cartridge, the valve cartridge comprising: a first fixed disk to guide hot and cold water flowing from outside water pipes into a valve cartridge through hot and cold water inlet holes thereof; a rotary disk with a temperature control hole formed through the rotary disk, so that the rotary disk controls by rotation the flow rate of hot and cold water according to an amount that the temperature control hole overlaps the hot and cold water inlet holes of the first fixed disk to control the temperature of water; a second fixed disk with a water passage hole formed through the second fixed disk to correspond to a predetermined rotational angular range of the temperature control hole of the rotary disk, thus guiding the hot water, cold water or the mix of the hot and cold water in the valve cartridge, the second fixed disk also supporting the rotary disk against the first fixed disk; a temperature control unit coupled to the rotary disk at a first end thereof and received into a cartridge housing at a second end thereof such that the second end is exposed outside the cartridge housing, with a temperature control lever coupled to the exposed second end of the temperature control unit so that the temperature control unit rotates the rotary disk within a predetermined rotational angular range upon rotation of the temperature control lever; first, second and third water discharge holes formed through the first fixed disk, the rotary disk and the second fixed disk, respectively, such that the first, second and third water discharge holes communicate with each other to discharge the hot water, cold water or the mix of the hot and cold water from the valve cartridge; a moving unit adapted to linearly move toward or away from the water discharge hole of the second fixed disk for controlling a gap between the moving unit and the water discharge hole of the second fixed disk to control the flow rate of discharged water; and a flow rate control unit adapted to receive therein the moving unit to cause the linear movement of the moving unit, the flow rate control unit being inserted through a stop bushing into the temperature control unit such that an end of the flow rate control unit protrudes from the temperature control unit; the stop bushing configured to prevent the interference between flow rate control unit and temperature control unit.
