Thermostat Maintenance

After the thermostatic faucet is used for a period of time, there will be problems such as a significant reduction in water output or inaccurate temperature adjustment. The main problem is that impurities block the water inlet gasket of the thermostatic faucet and impurities block the thermostatic valve core. At this time, the thermostatic valve core and gasket must be cleaned.

The specific method is as follows:

Remove the fixing screw on the back of the thermostatic faucet, pull out the thermostatic valve core (be careful not to remove the handwheel on the thermostatic valve core), clean the filter screen on the thermostatic valve core with a toothbrush or brush, then rinse with water to remove the filter screen If the dirt is removed, put the valve core back into the faucet, and screw on the fixing screw.

The concept of constant temperature

The so-called constant temperature refers to: according to your needs, pre-set the temperature, within a certain range, the temperature and pressure of the hot and cold water supply will change, and the thermostatic faucet will be automatically adjusted inside, so that the water temperature is always stable at your preset temperature. set temperature (float range 1 ). The constant temperature control is the outlet temperature of the mixed water, that is, the temperature of the terminal outlet water, while the “constant temperature” of some water heater manufacturers on the market refers to controlling the heating temperature of the hot water.

Why should you use a thermostat?

1When you are going to take a bath, you must stand on the side and turn on the faucet to test the temperature of the water with your hands. When the temperature of the water is not suitable, you must turn the handle to adjust. Sometimes we may have to make repeated adjustments to find the right temperature. temperature, this process wastes a lot of water and electricity. And if we use our thermostatic faucet, it will not be so troublesome. Before turning on the flow of the faucet, you only need to pre-tighten the temperature control handwheel to the temperature line you want. Such a water outlet temperature is a comfortable shower temperature. , and then turn on the flow switch on the other side of the faucet to use.

2While we are taking a bath, if the neighbors or other faucets in our home are turned on, the temperature of the outlet water will change immediately due to the change in the water pressure of the water supply. When the cold water is adjusted again, the water heater will be turned off again, which is really annoying. This is more common in hotels, high-rise residential buildings, public baths, saunas, clubs, and fitness and beauty salons (because there are many people taking baths at the same time, resulting in more hot and cold conditions). When this happens, we need to adjust again, and the process of re-adjustment is a process of wasting water and electricity. This situation will not happen with the thermostatic faucet. When the water pressure and water temperature of the water supply change, the thermostatic faucet willautomatically adjust the mixing ratio of cold water and hot water in a very short time ( 1 second), so that the water can be discharged. The temperature continues to stabilize at the preset temperature.

3.Each of our families has elderly and children. When they use the faucet, sometimes they will turn the handle of the ordinary faucet to the left or the right when they are not careful, which will cause unsafe factors. And our thermostatic faucet has a unique design in this regard, and a safety protection button is set on the thermostat handwheel to avoid the possibility of unsafe factors.

4Anti-scaling coating: when the water quality is poor; the proportion of calcium ions is large, so the faucet is very easy to scale (ordinary faucets will be very difficult to move the handle after a long time, and the water flow will become smaller, etc., these It is caused by scaling inside the faucet), and our thermostatic faucet adopts the thermostatic valve core imported from France. The valve core is made of special materials, so there will be no scale on the surface of our valve core, even if it is used for a long time. affect product performance.

5Safety: Our thermostatic faucet will automatically turn off in a short period of time when the hot water supply is lost (power failure), and will not cause burns and discomfort to the user due to the high (or low) temperature of the outlet water due to the water cut off. .

Thermostatic mixer

The thermostatic faucet can also be called a thermostatic faucet or a thermostatic mixing faucet. Its function is to automatically mix cold water and hot water into warm water at a preset temperature.

The early cold and hot water mixing faucet is a double knob faucet (Two Handle Mixer). The hot water mixing faucet is a single lever mixer, and its core is a ceramic temperature regulating valve core. The user can adjust the temperature of the mixed water by swinging the handle left and right, and the water output can be adjusted by swinging the handle up and down. However, when the water pressure of hot or cold water changes suddenly, or when the temperature of hot water changes suddenly, the above two mixing faucets must be manually operated to re-adjust the water temperature.

The thermostatic faucet can automatically balance the water pressure of cold water and hot water in a very short period of time through the thermostatic adjustment valve core that comes with the faucet, so as to keep the water temperature stable, and no manual adjustment is required at all.

Thermostatic faucets have long appeared in Europe. At present, there are mainly two automatic temperature adjustment methods, which use different thermostatic valve cores :

One is the paraffin thermostatic element (Wax Element) valve core.

The working principle of the paraffin temperature sensing component is to pour high-purity special paraffin into a small copper container, and the container mouth is covered with a rubber sensing piece. Due to the change of water temperature, the volume of paraffin in the container also increases and shrinks, and then the spring pushes the piston through the sensor sheet at the mouth of the container to adjust the mixing ratio of cold and hot water. At present, the thermostatic valve core is mainly used by European manufacturers.

Another thermostatic valve core uses shape memory alloy (Shape Memory Alloys for short SMA) spring.

The important part of the SMA thermostatic valve core is the shape memory alloy spring. The shape memory alloy spring made of nickel-titanium (Ni-Ti) alloy changes its shape by sensing the temperature of the warm water after mixing, thereby pushing the piston to adjust the hot and cold water. mixing ratio. The SMA thermostatic valve core has a fast response speed and a sensitive response around 40°C, which can meet the needs of users for fine-tuning. At present, the thermostatic valve core is mainly used by Japanese manufacturers.

Since the thermostatic valve core is a very precise device, no matter which form is used, the internal processing of the valve core thermostatic faucet shell is also required to be very precise. The tolerance of all internal processing dimensions should be limited to within ±0.1mm, and the tolerance of important dimensions must be Controlled within ±0.05mm.

Thermostatic faucets are suitable for shower facilities in homes, hotels, public bathrooms, and barbershops and other environments where water pressure changes frequently.

Thermostatic Cartridge

The thermostatic valve core is a device that automatically adjusts the mixing ratio of cold and hot water, so that the temperature of the mixed water can be automatically maintained at the set temperature.

The first generation of thermostatic valve core adopts paraffin thermostatic element (Wax Element).

The working principle of the paraffin temperature sensing component is to pour high-purity special paraffin into a small copper container, and the container mouth is covered with a rubber sensing piece. Due to the change of water temperature, the volume of paraffin in the container also increases and shrinks, and then the spring pushes the piston through the sensor sheet at the mouth of the container to adjust the mixing ratio of cold and hot water.

However, the paraffin thermostatic valve core has always had shortcomings such as slow response speed and excessive temperature instantaneous overshoot. The instantaneous temperature overshoot value means that when the thermostat adjusts the temperature, it first exceeds the target temperature instantaneously, and then returns to the target temperature. The instantaneous overrun value of the paraffin thermostatic valve core is about 5°C ~ 10°C.

The second-generation thermostatic spool uses Shape Memory Alloys (SMA for short) springs.

The important part of the SMA thermostatic valve core is the shape memory alloy spring. The effective working temperature range of the shape memory alloy spring made of nickel-titanium (Ni-Ti) alloy is 0 °C ~ 100 °C.

The SMA thermostatic valve core has a fast response speed, and the instantaneous temperature exceeding value can be controlled below 2 °C. Moreover, the SMA thermostatic valve core has a sensitive response around 40°C, which can meet the needs of users for fine-tuning.

In the SMA thermostatic valve core, the shape memory alloy spring itself not only acts as a temperature sensing element, but also pushes the piston to adjust the mixing effect of cold and hot water, and the mixed water can also pass through the spring, which saves valuable space. Make the thermostatic valve more delicate.

As a core device, thermostatic valve core is widely used in thermostatic water heaters and thermostatic faucets .

When the water pressure of hot or cold water changes suddenly, or the temperature of hot water changes suddenly, the thermostatic regulating valve core can automatically balance the water pressure of cold water and hot water in a very short time to maintain the water temperature It is stable and does not require manual adjustment at all.

Since the thermostatic valve core is a very precise device, no matter whether the first or second generation of the thermostatic valve core is used, the internal processing of the thermostatic water heater or the thermostatic faucet housing where the thermostatic valve core is installed also requires very precise, all internal processing The tolerance of dimensions should be limited to within ±0.01mm, and the tolerance of important dimensions must be controlled within ±0.005mm.

The working principle of the thermostatic faucet:a heat-sensitive element is installed at the mixing outlet of the valve body of the equipment. The characteristics of the temperature-sensing element are used to push the valve core to move, and the water inlet of cold and hot water is blocked or opened. Turn on hot water at the same time as cold water. When the temperature adjustment knob sets a certain temperature, the ratio of cold and hot water entering the water outlet will also automatically change, so that the water temperature will always remain constant. The temperature adjustment knob can beset arbitrarily between 35°C and 65°C, and the constant temperature water mixer will automatically maintain the set outlet water temperature.

Precautions for installation and use of thermostatic faucets:

* Users with small solid lumps in the tap water are not suitable for using the thermostatic faucet;

* If the tap water contains powdery sediment or soft foreign matter, the sensitivity of the thermostatic valve core may be reduced, and the service life of the thermostatic faucet may also be shortened;

* Minimize the distance between the water heater and the faucet so that the hot water can reach the faucet as soon as possible;

* The normal water pressure is 0.05Mpa ~ 0.6 Mpa;

* The hot and cold water supply pipes cannot be installed wrongly, the hot water pipe must be on the left, and the cold water pipe must be on the right;

* Be sure to clean up the installation site before installing the thermostatic faucet, so as not to damage the rubber ring, thread, thermostatic valve core and other parts of the faucet by small sand and stone blocks;

* Please install according to the instructions of the manual, pay special attention not to miss, lose or damage any gaskets or rubber rings;

* The thermostatic faucet itself has no heating function, please adjust the water temperature of the water heater to 60°C ~ 85°C;

* Showers and shower pipes cannot withstand high temperatures above 60°C;

* After each use, be sure to adjust the water temperature adjustment knob on the left to below 40°C;

* If the water pressure of hot water and cold water is too different, please use a screwdriver to adjust the valve of the bracket. Families using gas water heaters need to pay more attention to this.

 How to use the thermostatic faucet:

The standard thermostatic faucet has a knob on the left and right, and the knob on the right adjusts the water temperature: if you screw it forward, the water temperature will drop; if you screw it backward, the water temperature will rise, but it will not turn when it reaches 40°C. This is because it is easy to burn the skin when the water temperature exceeds 40°C. If you need hot water with a higher water temperature, you must press and hold the red safety button on the knob before you can continue to screw it back.The knob on the left controls the water outlet method and water volume: when the scale is aligned, it is in the closed state; screw it forward, the water outlet nozzle below will flow out, and the more you screw it forward, the greater the water volume; screw it backward, the shower will emit water, and the further you screw it back, the greater the water volume. .
