The current water heater market is mainly based on electric water heaters and gas water heaters. Among them, gas water heaters have received more attention. What is the principle of gas water heaters ? The following decoration home decoration network Xiaobian will bring you the working principle of gas water heaters, I hope to be helpful to everyone.
What is the principle of a gas water heater?
The working principle of the gas water heater is that the cold water enters the water heater, and flows through the water-gas linkage valve body to push the water-gas linkage valve under the action of a certain pressure difference of the flowing water, and simultaneously pushes the DC power micro-switch to turn on the power and start the pulse igniter. At the same time, the gas transmission electromagnetic valve is opened, and the ignition is continued automatically by the pulse igniter until the ignition successfully enters the normal working state, and the process is continuously maintained for 5 to 10 seconds, when the gas water heater is in the working process or the ignition process When there is a shortage of water or insufficient water pressure, lack of electricity, lack of gas, hot water temperature, accidental blowout, etc., the pulse igniter will automatically cut off the power by detecting the feedback signal from the induction needle, and the gas transmission solenoid valve is missing. In the case of electricity, the original normally closed valve state is immediately restored, that is to say, the gas has been cut off at this time, and the gas water heater is turned off to provide safety protection.
Usually a qualified gas water heater refers to the gas water heater whose performance index meets the national standard of GB6932-2001 "Household Gas Rapid Water Heater". The whole process from ignition state to normal working state is fully automatic control, no need for artificial adjustment or Additional settings, as long as the cold water switch is turned on or the cold water source is turned on, the water volume adjustment device and the gas volume adjusting device are adjusted to obtain the appropriate water quantity and water temperature, and the gas water heater immediately enters the normal working state within a short time of 5 to 10 seconds, and simultaneously produces Hot water, once the above accidental failure occurs, the gas water heater will automatically stop working within 10 seconds, and immediately cut off the gas, prevent the gas from continuing to flow out, and can not automatically re-open, unless the above fault is manually removed and then restart the gas water heater , in order to work normally, so its performance is safer and more reliable.
How big is the temperature of a gas water heater?
Gas water heaters generally have a temperature range of 35-65 degrees , which is actually related to the inlet water temperature and the amount of water flow, as well as the amount of gas. Take a 10L water heater as an example: its maximum load is 20 kW, which can heat water of 10L/ min flow by 25 degrees. When the water flow is reduced, the temperature naturally rises. Similarly, the gas is reduced or the temperature of the water flow is naturally low. This is adjusted by the user. If it is a constant temperature water heater, the machine will automatically adjust to the user's own setting within a reasonable range and conditions. temperature.
The above is what is the principle of gas water heater brought by Xiaobian? The whole working principle of gas water heaters, I believe that everyone has a basic understanding of the gas water heater principle after reading this article, if you want to know more about decoration consultation, please click to enter the decoration knowledge channel .
