Abstract: A water flow temperature control system is described. A hot and cold water flow respectively flow through a first and a second inlet passage of a valve and reach a temperature control sheet through a pressure equalization valve and two water seals. The quantities of the water flows are controlled by changing positions of two large or two small tapered adjusting holes on the temperature control sheet relative to the two water seals before flowing towards a water mixer of a mixing device. The water flows enter from a large opening portion of the water mixer, and are mixed in a helical direction. After that, the water flows pass through a number of outlet holes on a small opening portion of the water mixer towards an outlet passage of the valve. The center of the temperature control sheet is connected to a first end of a transmission shaft.
