Metering valve system for a water heater

Abstract

A metering valve for a water heater system is provided. The metering valve is configured to selectively control the amount of water flowing into the water tank and / or cold-water bypass shunt through rotation of a rotor. The rotor is attached to the motor such that when the motor is driven, the rotor is rotated in either the clockwise or counterclockwise direction. The rotor is shaped such that, depending on the degree of rotation of the rotor, the size of the openings at the cold water inlet and the cold water bypass shunt (as well as the water inlet into the metering valve) are adjusted. That is, the ratio of water entering the tank and / or passing to the cold bypass shunt may be adjusted based on the degree of rotation of the rotor, which in turn controls the temperature of the water exiting the metering valve system at the outlet of the water tank. 20 26 20 02 75 15 J an 2 02 6 2 0 2 6 2 0 0 2 7 5 1 5 J a n 2 0 2 6 1 / 13 FIG. 1 100 Tank Memory Controller Metering Valve Bypass Shunt Mixing Tee Sensor(s) Water Source Load 101 102 104 108 110 112 114 116 118 120 105 111 112 114 100 Load 108 105 118 101 20 26 20 02 75 15 J an 2 02 6 2 0 2 6 2 0 0 2 7 5 1 5 J a n 2 0 2 6 1 1 0 1 0 4
