Description
Technical field
The utility model relates to a kind of component devices of solar water heater system, is specifically related to a kind of water-saving anti-freezing apparatus of solar water heater.
Background technology
Solar water heater is accepted by masses because of its convenient and practical characteristic, but the following point that solar water heater can run into while using:
First what 1, open that shower nozzle goes out is cold water, only after cold water discharges, just has hot water to use, and this cold water is present in waterpipe, cannot be heated, and has virtually caused the waste of water resource, and pipeline is longer, wastes larger;
2, when day cold, the water in solar energy water heater pipe is easy to be frozen in, causing hot water in solar water container can not put out maybe cannot be to water on solar water heater, has affected the use of solar water heater in winter.
Utility model content
The purpose of this utility model is for deficiency of the prior art, provides a kind of simple in structure, uses safe solar water heater water-saving anti-freezing apparatus.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Solar water heater water-saving anti-freezing apparatus, comprises water tank and the water inlet pipe and the outlet pipe that are connected with water-heater water tank water inlet and delivery port respectively, and its innovative point is: in described water tank, be provided with level sensor and the first temperature sensor; Described water inlet and delivery port are arranged at water tank both sides, and water inlet pipe and water tank junction are provided with water level controller, and outlet pipe and water tank junction are provided with water check valve; On described water inlet pipe, be provided with water intaking valve and purge valve, purge valve arranges between water intaking valve and water inlet; On described outlet pipe, be provided with the second temperature sensor, remaining water controller, remaining water recovery tube and outlet valve, remaining water controller is arranged at remaining water recovery tube and outlet pipe junction; On described remaining water recovery tube, be provided with circulating-water valve and another purge valve.
Further, described the second temperature sensor is arranged between remaining water controller and delivery port.
Further, described water-heater water tank is pressure-bearing type or non-bearing type.
The beneficial effects of the utility model: by arranging of temperature sensor, the cold water in outlet pipe is transported to water tank again, prevents water resource waste, outlet pipe and water tank junction arrange water check valve, after shower finishes, the water in outlet pipe can be discharged completely; Utilize purge valve on water inlet pipe and Yu Shui recovery tube can drain in remaining water, the utility model effectively solves water pipe frozen block problem in winter, has saved greatly water resource.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is elaborated.
A kind of solar water heater water-saving anti-freezing apparatus as shown in Figure 1, comprises water tank 1 and the water inlet pipe 2 and the outlet pipe 3 that are connected with water-heater water tank water inlet and delivery port respectively, is provided with level sensor 11 and the first temperature sensor 12 in water tank 1; Water inlet and delivery port are arranged at water tank 1 both sides, and water inlet pipe 2 is provided with water level controller 4 with water tank 1 junction, and outlet pipe 3 is provided with water check valve 5 with water tank 1 junction; On water inlet pipe 2, be provided with water intaking valve 21 and purge valve 22, purge valve 22 arranges between water intaking valve 21 and water inlet; On outlet pipe 3, be provided with the second temperature sensor 31, remaining water controller 32, remaining water recovery tube 33 and outlet valve 34, remaining water controller 32 is arranged at remaining water recovery tube 33 and outlet pipe 3 junctions; On remaining water recovery tube 33, be provided with circulating-water valve 35 and another purge valve 36.
Operation principle: signal is passed to water level controller 4 by the level sensor 11 in water tank 1, control the keying of water intaking valve 21, in the time that the interior temperature of water tank 1 reaches lower limit, automatically open 21 moisturizings of water intaking valve, when water level reaches higher limit, automatically close 21 of water intaking valves, then open purge valve 22, the water in water inlet pipe 2 is discharged; The first temperature sensor 12 in water-heater water tank 1 is responded to the water temperature value in water tank, and the second temperature sensor 31 on the pipeline of outlet pipe 3 induces the water temperature value in water pipe; Whether the water temperature value that the second sensor 31 induces in water pipe 3 equates with the water temperature value in water-heater water tank 1, if the water temperature value in outlet pipe 3 is lower than the water temperature value in water tank 1, the second temperature sensor 31 was collected signal and was passed to remaining water controller 32, now, close the outlet valve 34 on outlet pipe 3, start the circulating-water valve 35 on remaining water recovery tube 33, the low-temperature cold water in pipeline is recycled in solar water heater water tank 1; When identical, now open the outlet valve 34 on outlet pipe 3 with 1 water temperature in water tank when the interior water temperature of outlet pipe 3, close the circulating-water valve 35 on remaining water recovery tube 33; Outlet pipe 3 and water tank 1 junction arrange water check valve 5, after shower finishes, open water check valve 5, and the water in outlet pipe 3 can be discharged completely, and the water in remaining water recovery tube 33 is discharged by another purge valve 36.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
