The solar water heater solenoid valve is a very important device in solar water heaters. It mainly plays two very important role in solar water heaters.One is to replace the switch or valve manually, and the other is to automatically open the valve and letting water automatically open the water when the solar water heater is automatically exhausted.

Solar water heater electromagnetic valve failure
1. Failure performance: It does not operate in the case of power.Cause analysis: There are more likely to occur in this situation. It may be caused by poor wiring contact at the power supply. It may be that the transformation of the power supply voltage may cause the wires to be burned or short -circuit.Solution: Pay attention to check and exclude, connect the power cord, and adjust the voltage to keep it in a stable range.Can replace the coil.2. Failure performance: When the valve is opened, the fluid cannot pass.Cause analysis and corresponding methods: There are also many cases of this failure. First, the pressure of fluid or the pressure difference between its work does not meet the normal operating range. At this time, you need to adjust the pressure or work pressure difference;A large amount of dirt impurities are mixed in the valve core or in the place where the moving iron core. At this time, you need to clean it inside; the third is that the filter in front of the valve is blocked. At this time, clean the filter.
Solar water heater induction valve installation
1. Rinse the pipe before installation to rinse the impurities.2. If the water tower is water supply, please choose to adapt to the solenoid valve with the water pressure.Therefore, the solenoid valve can not be too water or the flow is too small.3. Check whether the solenoid valve identification is consistent with the output voltage of the control power supply. Check whether the filter is complete and whether the valve body is not damaged.
Solar water heater electromagnetic valve working principle
The principle of solar electromagnetic valve control water heater adding water is used in popular engineering language. A control circuit of an automatic water is very simple. You can add a liquid level electrode in solar energy (can be used with galvanized round steel or stainless steel).The electrode is connected with a 24VDC power supply positive pole, connects a 24VDC relay, and controls the solenoid valve with relays.The two electrodes are one length (lower limit) and one short (upper limit). When the water level is at the lower limit, that is, the water does not have a long electrode, the relay must not be electrical, and the solenoid valve is turned on the water.When the water level rises to the upper limit, the two electrodes are guided by water through the water, the relay is obtained by the relay, and the solenoid valve is closed to stop the water.And you can control the automatic water with a float switch, so that the circuit is simple, as long as the power is stringed on the float switch, the relay is controlled by the switch, and the reptom is controlled by the relay.The principle of the water surface reaches the upper limit of the float switch.
