The circulating water supply system of aforesaid solar water heater, be provided with first temperature-sensitive head in described wherein any glass heat collection tube, wherein be provided with second temperature-sensitive head in another glass heat collection tube arbitrarily, second temperature-sensitive head and the 3rd temperature-sensitive head that is located in the attemperater are respectively the high and low temperature probe that lead-in wire picks out on the same temperature controller.

The circulating water supply system of aforesaid solar water heater, the end of recycling outlet communicates with the running water water inlet, be provided with check valve, normally closed solenoid valve, the 4th temperature-sensitive head between the two successively, wherein the 4th temperature-sensitive head and first temperature-sensitive head are respectively low, the high-temperature probe that lead-in wire picks out on the same temperature controller.

The circulating water supply system of aforesaid solar water heater, the mouth of pipe of every glass heat collection tube and with the intersection of tube connector, metal thin tube, be provided with the Capsule cover, its outside is fixing with larynx hoop chucking.

The circulating water supply system of the solar water heater of said structure, owing to become the passive cold and hot cold and hot exchange that is exchanged for active, become passive circulation and be active cycle, can improve utilization efficiency of heat energy greatly, not only the hot water output time is short, speed is fast, and the formation of incrustation and the waste of hot water have been avoided, do not need support during installation, can be directly installed on the ground, very convenient, glass heat collection tube links to each other with circulating water pipe with metal thin tube by tube connector, and water leakage was little when pipe was damaged, can not impact water system.

Description of drawings

Below in conjunction with accompanying drawing embodiment structure of the present utility model and advantage are further described.

Fig. 1 is the structure principle chart of described utility model.

The specific embodiment

Referring to Fig. 1, a kind of circulating water supply system of solar water heater is provided, comprise the glass heat collection tube 2 that attemperater 1 and some Zhi Pinghang arrange, glass heat collection tube 2 concrete quantity are decided on the output of required hot water.Be connected with circulation water inlet pipe 3 and recycling outlet 4 on the attemperater 1, be parallel with some tube connectors 5 on the circulation water inlet pipe 3, the quantity of tube connector 5 is corresponding with glass heat collection tube 2, every tube connector 5 is connected the mouth of pipe of circulation water inlet pipe 3 with pairing glass heat collection tube 2 respectively, be parallel with some metal thin tubes 6 on the recycling outlet 4, its diameter is generally about 5mm, can select aluminum pipe, copper pipe or stainless steel tube.The quantity of metal thin tube 6 is corresponding with glass heat collection tube 2, and every metal thin tube 6 inserts from the mouth of pipe of pairing glass heat collection tube 2 respectively, is inserted into pipe position, the end always.

Referring to Fig. 1, the described right side is risen and is provided with first temperature-sensitive head 7 in first glass heat collection tube 2, right rising is provided with second temperature-sensitive head, 8, the second temperature-sensitive heads 8 and the 3rd temperature-sensitive head 9 that is located in the attemperater 1 in second glass heat collection tube 2, be respectively the high and low temperature probe that lead-in wire picks out on the same temperature controller.Generally can set by electric-control system, when glass heat collection tube 2 water temperatures and the attemperater 1 water temperature temperature difference reach 5-10 ℃ of left and right sides of setting value, temperature-sensitive head passes the signal to temperature controller, send control signal by temperature controller, water circulating pump starts, hot and cold water begins to circulate, detailed process is: water colder in the attemperater 1 is through recycling outlet 4, metal thin tube 6 flows to glass heat collection tube 2 bottoms, because cold water density is greater than hot water density, enter into the colder current in glass heat collection tube 2 bottoms, water hot in the glass heat collection tube 2 will be extruded on one's own initiative, through tube connector 5, circulation water inlet pipe 3 flows to attemperater 1, carry out so repeatedly, can reach active cold and hot exchange, the purpose of active circulation; Can set equally, when glass heat collection tube 2 water temperatures and the attemperater 1 water temperature temperature difference reached 5-10 ℃ of left and right sides of setting value, temperature-sensitive head was sent to temperature controller with temperature signal, sends control signal by temperature controller, water circulating pump stops, and hot and cold water stops above-mentioned circulating.Obviously, because initiatively hot water is extruded glass heat collection tube 2 carries out cold and hot exchange by cold water, heat exchanger effectiveness is higher, and the hot water output time is short, speed is fast, and the water temperature and the attemperater 1 interior water temperature temperature difference are less in the glass heat collection tube 2, can not form incrustation.

Referring to Fig. 1, the end of recycling outlet 4 communicates with running water water inlet 10, be provided with check valve 11, normally closed solenoid valve 12, the 4th temperature-sensitive head 13 between the two successively, wherein the 4th temperature-sensitive head 13 and first temperature-sensitive head 7 are respectively low, the high-temperature probe that lead-in wire picks out on the same temperature controller.Can be set in by time controller certain time in the afternoon, when afternoon, five thirty, the sun set, the heat exchange of water and glass heat collection tube 2 interior water stops automatically in the attemperater 1, at this moment the hot water temperature who is deposited in the glass heat collection tube 2 will be higher than the running water temperature, temperature-sensitive head is sent to temperature controller with temperature signal, send control signal by temperature controller, control normally closed solenoid valve 12 is opened automatically, running water is through normally closed magnetic valve 12, check valve 11, metal thin tube 6 flows into glass heat collection tube 2 bottoms, the hot water of being deposited in the glass heat collection tube 2 is extruded, through tube connector 5, circulation water inlet pipe 3 flows to attemperater 1.Like this, just avoided hot water to accumulate in the glass heat collection tube 2 and the thermal waste that is caused in the pipeline.In the practical operation, low, high-temperature probe that said process also can remove temperature controller and be picked out, only need to set when five thirty, the sun set, normally closed solenoid valve 12 is promptly opened automatically, the water that running water is all replaced in glass heat collection tube 2 and the pipeline is just passable, this is the process of a moisturizing in fact just, and all can carry out every day on time, be not subjected to the influence of weather conditions.

The utility model does not need to help normally carrying out of heat exchange by support owing to be the mode that adopts above-mentioned active cold and hot exchange, active circulation, can directly glass heat collection tube 2 be installed on ground or the floor, and is very convenient.In addition, can on ground or floor, be coated with one deck heat insulating reflecting lacquer during installation, both can be heat insulation, can with ultraviolet reflection to glass heat collection tube 2, promote the fast rise of water temperature in the pipe again, the heat energy utilization effect is better.

Referring to Fig. 1, the mouth of pipe of every glass heat collection tube 2 and with the intersection of tube connector 5, metal thin tube 6, be provided with Capsule cover 14, its outside is fixing with larynx hoop 15 chuckings.This sealing mode is very tight, can avoid managing the drainage in a slit fully.This Capsule cover 14 is that materials such as silica gel or EPDM are made, utmost point weatherability and ultraviolet ray, and can reach many decades service life.

The foregoing description is a preferred embodiment of the present utility model, and all and the similar structure of the utility model and the equivalence of being done change, and all should belong to protection category of the present utility model.
