WATER FLOW TEMPERATURE CONTROL SYSTEM
First Claim
1. A water flow temperature control system, comprising:
- a valve, having a first inlet passage, a second inlet passage, an outlet passage, and an upper cover;
a pressure equalization valve, disposed in the valve, for controlling the quantity of a water flow flowing through the first inlet passage and the quantity of a water flow flowing through the second inlet passage, wherein the pressure equalization valve has a first chamber and a second chamber respectively disposed corresponding to the first inlet passage and the second inlet passage; and
a mixing device, having a temperature control sheet, a first water seal, a second water seal, a transmission shaft, and a water mixer, wherein the first water seal and the second water seal are pressed between the pressure equalization valve and the temperature control sheet and are disposed corresponding to the first chamber and the second chamber, the temperature control sheet has a number of adjusting holes disposed corresponding to the positions of the first water seal and the second water seal, the water mixer of a tapered funnel structure is disposed between the upper cover and the temperature control sheet and has a large opening portion and a small opening portion, the large opening portion is adjacent to the temperature control sheet and the small opening portion having a through-hole in the center and a number of water outlets is adjacent to the upper cover, a first end of the transmission shaft is connected to the temperature control sheet, and a second end of the transmission shaft is connected to a stepping motor through the through-hole and the upper cover so as to control the rotation of the temperature control sheet through the stepping motor.

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.
