The working principle of the thermostatic faucet is to use the temperature sensing element inside the valve core. This temperature sensing element is made of paraffin or Nitinol. It will change its shape according to the change of temperature, such as a component made of paraffin, when the water temperature changes, the volume of paraffin changes, and then the valve core ratio is adjusted by controlling the shaft, so that the water temperature can be adjusted to maintain a certain value. The temperature remains unchanged to achieve the effect of constant temperature water.

First, the working principle of the thermostatic faucet
The working principles of thermostatic faucets and thermostatic showers are similar. They all have a valve core, and this valve core has a temperature sensing element. This temperature sensing element is made of paraffin or Nitinol. It will change its shape according to the change of temperature, such as a component made of paraffin, when the water temperature changes, the volume of paraffin changes, and then the valve core ratio is adjusted by controlling the shaft, so that the water temperature can be adjusted to maintain a certain value. The temperature remains unchanged to achieve the effect of constant temperature water.

The valve core of the thermostatic faucet is very precise, so the premise is that the water quality must be very good. Poor water quality will affect the sensitivity of the valve core. When purchasing a thermostatic faucet, there are generally two filters installed in the water nut to filter impurities.

The function of the thermostatic faucet can only maintain a constant water temperature, it does not show the water temperature and the size of the water temperature; the scale of the handwheel of the faucet can only be an approximate value, which is inaccurate. Normally, the thermostatic faucet has overheat protection, which is about the 38° scale line. If you want to increase the water temperature, you must press the raised button to turn the handwheel.
Second, the installation and precautions of the thermostatic faucet
1. When the water pressure of hot water and cold water is too different, use a screwdriver to adjust the valve of the bracket.
2. The tap water contains powdery sediment or soft foreign matter, which will reduce the sensitivity of the thermostatic valve core and shorten the service life of the thermostatic faucet.
3. The hot and cold water supply pipes must not be installed wrongly, the hot water pipe must be on the left, and the cold water pipe must be on the right.
4. Clean up the site before installing the thermostatic faucet to avoid small sand and stone blocks from damaging the rubber ring, thread, thermostatic valve core and other parts of the faucet.
5. The thermostatic faucet itself has no heating function, please adjust the water temperature of the water heater to 60°C ~ 85°C.
6. After use, it is best to adjust the water temperature adjustment knob on the left to below 40°C.
The above is all about the working principle of the thermostatic faucet and how to install the thermostatic faucet. I hope it will be helpful to everyone.
