The three-way valve 10 is an electric and manual double control valve 11. The water tank 3 is fastened to the balcony wall in a bolted manner. The first pipe 7 which communicates the water tank 3 and the solar heat collector 1 is coated with a heat insulating material layer.
Then is combined withVariation exampleThe present invention will be further explained.
According to the utility model provides an electronic manual two accuse valves can be on basic embodiment, can adopt the three-way valve to be the motorised valve, and the motorised valve state is normally open state, sets up manual valve on the pipeline between the second end of three-way valve and heating equipment's water inlet. Thereby achieving the function of adjusting the water temperature setting electrically or manually.
The working principle is as follows:
running water passes through inlet channel 4, gets into water tank 3 from water tank water inlet 31, and rivers flow into solar collector's water inlet 8 through second pipeline 6 from circulation export 33, and rivers heat in solar collector 1 after, get into water tank 3 by circulation entry 34 through first pipeline 7 from solar collector's delivery port 9, and water tank 3 storage hot water, when needing to use hot water, rivers supply to use along outlet conduit 5 from water tank delivery port 32. When the electric valve senses that the water outlet temperature is higher than or equal to the set temperature, the water can not flow into the heating equipment and can be directly supplied to the outside; when the electric valve senses that the outlet water temperature is lower than the set temperature, the outlet water flows into the heating equipment, and hot water is supplied after the heating equipment heats the outlet water. Aiming at the preference of different people to the temperature of hot water, the electric and manual double control valve can be manually opened to manually control whether the water flow is heated by the heating equipment and then the hot water is supplied.
Based on the utility model provides a hardware platform helps realizing automatic control by temperature change, for example through further improving: a temperature sensor is arranged at the upstream of the three-way valve, and when the temperature is lower than a set threshold value, the heating equipment starts to automatically heat; when the temperature is higher than the set threshold value, the heating device does not perform automatic heating.
