Solar Energy Solenoid Valve
Solar Energy Solenoid Valve
Application for the solar valve
Solar water heater, electromagnetic valve, is like a switch when the sensors detect the casing water level is lower than the set water level, the motherboard will provide + 12 v voltage for electromagnetic valve when getting the voltage solenoid valve coil, the electromagnetic valve opens, as the solar energy water, when the sensor detects the water tank water level to set, the mainboard will stop to power a solenoid valve, solenoid valve closed, water stop.
The solenoid valve of the solar water heater
The principle of electromagnetic valve control solar energy water heater water use is a common engineering language, a control circuit is simple, automatic water can add a level electrode in solar energy (use galvanized round steel or stainless steel), on two electrodes series connected to 24 VDC power supply positive, external a 24 VDC relays, relay control solenoid valve. Two electrodes one long (lower limit) and one short (upper limit), when the water level is a lower limit, that is, the water does not overspread the long electrode, the relay is not electricity, solenoid valve open water. When the water level rises to the upper limit two electrodes pass through the water, the relay receives electricity, the solenoid valve closes, and the water is stopped. You can also use the float switch to control the automatic water, so the circuit is simple, as long as the power line on the float switch, through the switch control relay, and then by the relay control solenoid valve. The principle the water surface reaches the upper limit float switch disconnects, the relay loses power disconnects the solenoid valve, the lower limit float switch connects the relay gets the power to connect the solenoid valve.
Solar water heater solenoid valve installation notes:
The function of the solar valveis to make the pipe check or directional flow, solenoid valve in the solar water heater water when it opens, let the cold water into the tank when the water stopped when the solenoid valve closed, then the solar water tank water can not flow back through the solenoid valve into the cold water pipe. If the solenoid valve is still closed when the water in the heater is used, the water can only flow into the hot water pipe and not into the cold water pipe. Generally speaking, the solenoid valve and the solar instrument are used together and should be fully automatic control, so it is not necessary to control the solenoid valve separately when testing the solar water heater.
The solar solenoid valve is divided into pressure and no pressure two, if the cold water pressure is relatively small it is best to choose no pressure valve, or the solenoid valve may not open, can not normally water; If the water pressure is larger, choose to have pressure valve, otherwise, the solenoid valve may not check, that is to say, the water in the water heater may be backflow into the cold water pipe or the solenoid valve cannot close, causing the water heater temperature rise not up.
Performance test method of the solenoid valve of the solar water heater:
