Introduction to the principle of constant temperature water heater
At present, the constant temperature gas water heater adopts the principle of proportional valve temperature control. A flow sensor is connected in series in the pipeline of the water heater. The gas valve is an electric control valve (proportional valve). The flow sensor converts the water flow into a corresponding electrical signal and inputs the signal into the controller. The controller adjusts the opening of the air valve according to the intensity or frequency of the input signal, so that the gas flow rate changes in direct proportion to the water flow rate, thus achieving the purpose of keeping the water temperature constant.
When the water heater works, the flow sensor can sense the water flow and water pressure, and send the signal to the proportional valve, which controls the number of fire rows, thus controlling the firepower and adjusting the water temperature.
Is the constant temperature water heater good?
1, comfortable
The constant heating water heater is fully enclosed, which can supply hot water at multiple points, at the same time, in large quantities and continuously, and the outlet temperature is constant, which is not affected by water pressure (air pressure), and there is no cold or hot phenomenon.
Step 2 facilitate
The water temperature of the water heater can be continuously adjusted and automatically kept constant to adapt to different water temperatures in different seasons. Once turned on, it will run automatically all year round. Just turn on the tap and supply hot water all day.
3. Safety
The water heater is equipped with multiple safety protection devices to fully protect personal safety. A variety of structures and forms can meet the needs of different users and different places.
4. Strong adaptability
Ordinary tap water pressure can generate hot water without starting water pressure. Preheating and storing hot water, low voltage will not affect the use, but also alleviate the contradiction of insufficient power supply during peak hours and reduce the power supply burden. Even if there is a power failure, there is still hot water supply.
Characteristics of constant temperature water heater
1. Convenience
The constant temperature water heater is automatically controlled at constant temperature without manual management, which is convenient, comfortable and energy-saving.
2. Good appearance design
It is painted with colored electrostatic powder and coated with aluminum-zinc steel plate shell, which is super rust-proof, and its rust-proof ability is 6 times that of ordinary galvanized steel plate, and it is as good as new after long-term use.
3. Long service life
The inner wall is glazed at high temperature, which can resist corrosion and high temperature, improve thermal efficiency, and automatically relieve pressure to ensure no leakage for five years.
Is the constant temperature water heater good? Only those who have used a constant-temperature water heater can give the most ideal and correct answer to this question, and those who have not used a constant-temperature water heater can only know a little. For ordinary families, you can buy a constant temperature water heater or a water heater that can adjust the temperature. After all, the temperature of hot water for bathing in different seasons should be different. If you keep a constant temperature, it may bring a lot of trouble to people and you can't take a bath smoothly.
