THERMOSTATIC FAUCET OPERATE
Cold or hot weather, open the faucet, the water flow is ice-cold, little partner is not want to home factory flow warm water, in fact, want to achieve is not difficult, install a thermostatic faucet can be solved. Here I introduce you to this faucet
Understanding the thermostatic faucet operation and its Key Features
A thermostatic faucet operates on a sophisticated mechanism that ensures consistent water temperature, enhancing comfort and safety. By utilizing advanced temperature-sensing technology, it maintains a stable water temperature regardless of variations in water supply or external factors. This technology enables users to enjoy a consistent and pleasurable water experience every time they use the faucet.
Thermostatic Mixer or thermostatic shower mixer, its role is to automatically mix cold and hot water into a pre-set temperature of warm water, and keep the set temperature unchanged, each time the water temperature is set on the use of the flow out of the temperature.
The faucet we commonly use at home is also called hot and cold water mixer faucet, generally through the rotation of the handle to control the amount of cold and hot water intake, so as to mix the water into the temperature we need.
The core is a ceramic piece of thermostatic spool, when the water pressure of hot or cold water suddenly changes, or the temperature of hot water suddenly changes, it is necessary for people to readjust the water temperature.
The working principle of thermostatic faucet
Thermostatic faucet and our common faucet at home is very similar, its core is self-contained thermostatic debugging spool, the spool has a temperature-sensing element. This element is usually made of paraffin or nickel-titanium alloy.
A. Wax Element Cartridge
The temperature-sensing element made of paraffin wax, high-purity special paraffin wax into a small copper container, the mouth of the container covered with a rubber sensing piece, will expand or shrink with the temperature, when the water temperature changes, the volume of paraffin wax changes, and then through the sensing piece at the mouth of the container to adjust the cartridge.
The cartridge and adjust the mixing ratio of cold and hot water, so that the water temperature can be adjusted to maintain the specified temperature Unchanged, to achieve the effect of constant temperature water.
Wax thermostat cartridge has been slow response speed, temperature instantaneous exceeded the value of too large and other shortcomings. The instantaneous temperature override value means that the thermostat, when adjusting the temperature, first crosses the target temperature momentarily, and then adjusts back to the target temperature.
The instantaneous exceedance value of paraffin thermostatic cartridge is about 5℃ ~ 10℃.
A large portion of the world’s thermostatic spools currently use this temperature-sensing element. In this kind of temperature sensing element, the purity of the temperature sensing paraffin wax is very high, and the processing and assembly of the parts must be very precise
B. SMA thermostatic cartridge
Thermostatic cartridge uses shape memory alloy (Shape Memory Alloys) spring. SMA thermostatic spool response speed is very fast, when the hot and cold water inlet pressure, temperature or water flow change, the change in water temperature within ± 2 ℃.
When the cold water is suddenly interrupted, the thermostatic mixing valve can automatically turn off the hot water within a few seconds, playing a safety protection role against scalding; when the hot water is suddenly interrupted, the thermostatic mixing valve controls the water temperature of the bathroom water pipe, through the “memory” function to adjust or close the water supply pipe, can automatically turn off the cold water within a few seconds, playing a safety protection role against cold shock.
So that the water temperature is maintained at the set temperature value, not affected by changes in hot and cold water inlet pressure, temperature or water flow, thus solving the problem of sudden hot and cold water temperature during the bathing process thermostatic mixing valve with automatic constant water temperature function, the water temperature according to the actual needs of the setting, the water temperature can be quickly reached and automatically constant.
SMA thermostatic spool not only responds very quickly, and the temperature instantly exceeds the value is controlled below 2 ℃, which greatly improves the comfort of the shower. Moreover, the SMA thermostatic spool is extremely responsive around 40℃, which can meet the user’s need for stepless fine-tuning.
In SMA thermostatic spool, the shape memory alloy spring itself both as a temperature-sensitive element, but also to push the piston to adjust the hot and cold water mixing role, and the mixed water can also pass through the spring, which saves valuable space, so that the thermostatic spool becomes more compact.
Thermostatic spool is a very precise device, no matter which form spool thermostatic faucet shell internal processing also requires very precise, all internal processing size tolerance should be limited to ± 0.1mm, important size tolerance must be controlled within ± 0.05mm.
Temperature of the thermostatic faucet
- Temperature standard requirement 38+ degrees.
- Cold water inlet dynamic water pressure 0.3+0.01Mpa, cold water temperature room temperature < 25 degrees.
- Hot water inlet dynamic pressure 0.3+0.01Mpa, hot water temperature 60-65 degrees.
The advantages of thermostatic faucets
1. Active Thermostat
The thermostatic mixing valve has the function of active stabilization of water temperature, water temperature according to the practical needs of the setting, the water temperature can be quickly reached and active stabilization.
Not affected by the hot and cold water inlet pressure, temperature or water flow change, and then deal with the bathing process of water temperature hot and cold questions. When the hot and cold water inlet pressure, temperature or water flow change, the water temperature change is within ±2℃.
2. Anti-scalding and anti-cold shock
The thermostatic mixing valve with anti-scalding and anti-cold excitation function, in the bathing process, when the cold water is suddenly suspended, thermostatic mixing valve can actively close the hot water within a few seconds, to prevent scalding safety maintenance effect.
When the hot water is suddenly suspended, thermostatic mixing valve can actively close the cold water within a few seconds, to prevent cold excitation safety maintenance effect.
Unlike traditional faucets, which can experience fluctuations in water temperature due to changes in water pressure or usage elsewhere in the plumbing system, a thermostatic faucet ensures temperature stability. It utilizes a built-in thermostat that reacts to temperature changes instantly, making automatic adjustments to maintain the set temperature.
This feature not only eliminates sudden cold or hot water surprises but also prevents potential scalding accidents.
3. High temperature resistant
The internal components of the thermostatic mixing valve are high-temperature resistant materials, which can operate normally at a temperature of 100 ℃.
Safety is a paramount consideration in any plumbing fixture, and thermostatic faucets excel in this aspect. They are equipped with anti-scald technology that effectively prevents water from reaching dangerously high temperatures.
The faucet’s design incorporates a maximum temperature limit, ensuring that the water remains within safe ranges, especially important in homes with young children or elderly individuals.
4. One-way check valve
The thermostatic mixing valve comes with a one-way check valve to avoid the hot and cold water inlet pressure is not the same, hot and cold water cascade.
5. Self-contained filter
The thermostatic mixing valve comes with a filter to avoid debris into the valve body and affect the normal operation of the thermostatic mixing valve.
6. Water-Saving Technology
Thermostatic faucets often feature water-saving technologies that promote eco-friendly usage.
These faucets come with flow control mechanisms that regulate water flow while maintaining the desired temperature.
By reducing unnecessary water wastage, they contribute to water conservation efforts and help minimize utility bills.
Conclusion:
Thermostatic faucets revolutionize the way we experience water, combining precise temperature control, stability, and safety features.
With their ability to maintain constant water temperature and prevent scalding accidents, these faucets offer a luxurious and worry-free water experience. Additionally, their water-saving technologies contribute to environmental sustainability.
Consider investing in a thermostatic faucet for your home or commercial space to enjoy the ultimate combination of comfort, safety, and efficiency in your daily water activities.
