What Is a Thermostatic Mixing Valve?

Thermostatic mixing valve is a supporting product of heating system, widely used in electric water heaters, solar water heaters and centralized hot water systems. It can also be applied to electric water heaters and solar water heaters. Users can adjust the temperature of mixed hot and cold water according to their needs. The required temperature can be quickly reached and stabilized to ensure that the temperature of the water is constant and not affected by changes in water temperature, flow and water pressure. The effect is to solve the problem of sudden cold and hot water temperature in the bath center. When the cold water is interrupted, the water mixing valve can automatically close the hot water within a few seconds to play a safety protection role.

The impact, to solve the problem of the water temperature in the bath center is suddenly cold and hot. When the cold water is interrupted, the water mixing valve can automatically close the hot water within a few seconds, which plays a role of safety protection ^[1]

At the mixing water outlet of the thermostatic mixing valve, there is a

1. The red mark is the hot water inlet. The blue mark is the cold water inlet.

2. After the temperature is set, if the water temperature or pressure changes, the value of the outlet water temperature changes within ± 2.

3. If the hot and cold water pressures are inconsistent, a one-way check valve should be installed at the water inlet to prevent cold and hot water from being interlinked.

4. If the pressure difference ratio between cold and hot water exceeds 8: 1, a current-limiting pressure reducing valve should be installed on the side with high pressure to ensure that the mixed water valve can be adjusted normally.

5. When selecting and installing, please pay attention to whether the requirements such as the nominal pressure and the temperature range of the mixed water are consistent with the product parameters ^[1]

1. When adjusting the temperature, the effluent flow should be maximized.

2. The forward rotation direction of the adjustment button is to decrease the temperature and the reverse rotation direction is to increase the temperature. Please pay attention to adjust from the low temperature direction to the high temperature direction for the first adjustment to prevent burns.

3. Adjust the knob in the low temperature direction to turn off the hot water at the end, and turn off the cold water in the end to the high temperature direction. If the temperature of the hot water is not high, you can turn off the cold water and use only hot water to take a bath. Burns occurred during use.

4. If the cold and hot water inlet pressures are inconsistent and no one-way check valve is installed, please note that after each use, turn the temperature adjustment button to the end of the low temperature direction, that is, turn off the hot water state to prevent cold and hot water to the greatest extent Mutual string ^[1] .
