The working principle of thermostatic taps are as follows: the outlet valve of thermostatic tapsis equipped with a thermal component which take characteristics of temperature components to promote the spool valve, closure or open hot and cold water inlet, when cold water blocking open the hot water at the same time. When set the temperature control knob to a certain temperature, hot and cold water into the outlet also will automatically change in proportion to effluent temperature is always constant. Thermostat knob can set temperature between 35 ℃-65 ℃, the thermostatic taps will automatically maintain the proper water temperature setted before.
Thermostatic taps on the market use memory alloy, paraffin, regulator valve, three ways to achieve the temperature effect. In general, the leading memory alloy thermostatic taps have a fast response to the temperature change, and the temperature deviation is small, which is the leading choice for thermostatic taps. Thermostatic taps have high requirment to the production process, so it is better to buy from big brands to ensure thermostatic taps' quality.
