Abstract
The utility model discloses a solar water heater system which can save water. The solar water heater system comprises a water storage tank and a user using water outlet which is connected with the water storage tank, wherein a stop valve is arranged between the water storage tank and the user using water outlet, a backflow branch is arranged between a water inlet of the stop valve and the water storage tank, and a control valve and a temperature sensor are arranged on the backflow branch. The stop valve, the control valve and the temperature sensor are in electric connection with a programmable logic controller (PLC) control panel. The backflow branch is additionally arranged, firstly the stop valve is closed, the control valve is opened, cold water in a pipeline flows into the water storage tank to be mixed, after the temperature sensor detects rising temperature of preset temperature, the control valve is closed, the stop valve is opened, hot water is supplied to a user to use, and all controlling movements are finished by the PLC control panel. The solar water heater system is simple in structure and reliable in working, can obviously save solar energy, and further improves adaptability of solar energy saving.
Description
Technical field
The utility model relates to technical field of solar water heaters, especially a kind of solar water heater system with backflow branch road.
Background technology
In known technical field of solar water heaters, when solar water heater uses in reality, in using pipeline between the delivery port, storage tank and user have certain ponding, and this ponding is generally cold water, especially winter, the perhaps resident family of high-storey, before use, must put first the cold water of a period of time, then could use hot water, cause certain water resource waste.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of can water-saving solar water heater system.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of solar water heater system with backflow branch road, comprise that storage tank and the user who links to each other with storage tank use delivery port, use described storage tank and user and to be provided with stop valve between the delivery port, between the water inlet of described stop valve and storage tank, also be provided with the backflow branch road, be provided with control valve and temperature sensor at described backflow branch road, described stop valve, control valve and temperature sensor all are electrically connected to the PLC control panel.
The beneficial effects of the utility model are: the utility model is by setting up the backflow branch road, and at first stop valve is closed, and control valve is opened, the cold water of pipeline the inside enters storage tank to be mixed, detect the temperature of default temperature rise when temperature sensor after, control valve is closed, and stop valve is opened, the hot water supply user uses, all control actions are finished by the PLC control panel, and this programme is simple in structure, reliable operation, can significantly save the solar energy water, further improve the applicability of energy-saving solar.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is theory structure schematic diagram of the present utility model.
Among the figure: 1. storage tank, 2.PLC control panel, 2-1. stop valve, 2-2. control valve, 2-3. temperature sensor.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of solar water heater system with backflow branch road of the utility model as shown in Figure 1, comprise that storage tank 1 and the user who links to each other with storage tank 1 use delivery port, use described storage tank 1 and user and to be provided with stop valve 2-1 between the delivery port, between the water inlet of described stop valve 2-1 and storage tank 1, also be provided with the backflow branch road, be provided with control valve 2-2 and temperature sensor 2-3 at described backflow branch road, described stop valve 2-1, control valve 2-2 and temperature sensor 2-3 all are electrically connected to PLC control panel 2.
At first stop valve 2-1 closes, control valve 2-2 opens, the cold water of pipeline the inside enters storage tank 1 to be mixed, detect the temperature of default temperature rise as temperature sensor 2-3 after, control valve 2-2 closes, stop valve 2-1 opens, and the hot water supply user uses, and all control actions are finished by PLC control panel 2.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
