Solar water heater solenoid valve working principle how to buy solar energy
The use rate of solar water heaters in rural areas is quite high, because the price of solar water heaters is a big advantage compared to other water heaters. Next, the decoration house is a small series, for everyone to introduce, solar water heater electromagnetic Valve, let's first look at the working principle of the solar water heater solenoid valve , and how to buy solar energy, I hope that the introduction of Xiaobian can help everyone.
First, the working principle of solar water heater solenoid valve
1. What is the solar solenoid valve? The principle of solar solenoid valve controlling the water heater to add water is in the popular engineering language. The control circuit of an automatic water supply is very simple. You can add a liquid level electrode to the solar energy or use galvanized round steel or Stainless steel can be connected to the 24VDC power supply positive pole on the two electrodes, then connected to a 24VDC relay, and the relay is used to control the solenoid valve.
2. The two electrodes have a long (lower limit) and a short (upper limit). When the water level reaches the lower limit, that is, the water does not flow over the long electrode, the relay is not energized, and the solenoid valve opens the water. When the water level rises to the upper limit, the two electrodes are turned on by the water, the relay is energized, the solenoid valve is closed, and the water supply is stopped.
3. Also, when we use the float switch to control the automatic water supply, the circuit is simple. Just connect the power supply to the float switch, control the relay through the switch, and then control the solenoid valve by the relay. The principle that the water surface reaches the upper limit of the float switch is disconnected, the relay loses power to open the solenoid valve, and the lower limit float switch turns on the relay to energize the solenoid valve. This is how the water heater solenoid valve works.
Second, how to buy solar energy
1. When buying a solar water heater, the first thing we must look at is its heating tube. If the heating tube is thicker, then the quality and quantity of solar energy will be large, so that we can use it very conveniently. It is.
2, then we have to look at the distribution of solar panels, if they are not the same distribution, the quality of solar energy will be relatively unqualified. I suggest you not to buy.
3, the most important point is the power of solar energy, if the solar energy is not big, is not enough, the population of the family, if the population of the family, it is best to buy a larger power, solar water heaters.
Solar water heater solenoid valve working principle, how to buy solar energy, Xiaobian is introduced to everyone here, after reading the above article, do you have a certain understanding of the solar water heater solenoid valve, if you want to understand More home improvement information, please continue to pay attention, decoration home network.
