Description

A kind of solar water heater liquid level display
Affiliated technical field
The utility model relates to a kind of solar-heating device, specifically a kind of solar water heater liquid level display.
Background technology
At present, along with improving constantly and the swift and violent upgrading of solar water heater product of living standards of the people, various Solar Enercy Fission Geysers, pressure-bearing water heater start to promote the use of gradually, its principle is to utilize solar energy heat collector being sent to the built-in heat exchanger in heat-exchanging water tank after thermal medium heating, and then the water in heat exchanging water tank carries out heat transmission and heats.Such heat exchange mode, can make thermal medium separate with required water, heat collector and water tank are installed respectively, circulate and the heat exchange of built-in heat exchanger by thermal medium, can improve heat transfer rate and efficiency, and then water tank can be made to pressure-bearing type, when assure feed water, have suitable pressure, can effectively meet pressure needs, be particularly suitable for installing at roof the skyscraper of solar water heater.But current known Solar Enercy Fission Geyser and wall-hanging solar water heater all use circulating thermal medium, because circulating thermal medium has the stronger performance of expanding with heat and contract with cold, thereby built-in heat exchanger top stores certain air, account for 1/3rd of whole built-in heat exchanger volume, thereby cause the well heat conduction of outer surface of this part volume, not even heat conduction, so radiating effect is poor, heat exchange efficiency is low, particularly when the liquid level of circulating thermal medium in built-in heat exchanger is during lower than the feed tube mouth of pipe, circulating thermal medium can not circulate, cause the built-in heat exchanger can not heat exchange.Have a strong impact on the development of Solar Enercy Fission Geyser and wall-hanging solar water heater.Also the Solar Enercy Fission Geyser having and wall-hanging solar water heater, adopt and in built-in heat exchanger, draw overflow pipe, be placed in the over top of press-bearing water tank, carry out direct exhaust by upper exhaust outlet, circulating thermal medium consumption is large, and need to installing hole be set respectively from press-bearing water tank, built-in heat exchanger, complex structure, easily causes poorly sealed.Particularly all solar water heaters all can not show the quantity of the circulating thermal medium in built-in heat exchanger, cause replenishment cycles thermal medium in time, have had a strong impact on heat exchange efficiency.
Utility model content
The purpose of this utility model is: overcome the well heat conduction of existing Solar Enercy Fission Geyser and wall-hanging solar water heater, not even heat conduction, radiating effect is poor, heat exchange efficiency is low, complex structure, poorly sealed, circulating thermal medium consumption is large, cannot show quantity, shortcoming that can not be supplementary in time, a kind of solar water heater liquid level display is provided, have simple in structure, easy for installation, circulating thermal medium consumption is little, can clearly show circulatory mediator quantity to supplement in time, can effectively improve the features such as solar water heater heat exchange efficiency.
The utility model solves the technical scheme that its technical problem adopts: this solar water heater liquid level display is mainly made up of overflow pipe, sealing ring, movable joint nut, cup, bidirectional relief valve; Described cup is transparent shell, and upper end oral area is provided with sealing ring, and overflow pipe passes from sealing ring, and the nearly top of the built-in heat exchanger in solar water heater water tank is inserted in its upper end, and the nearly bottom of cup is inserted in lower end; The right-hand member jiont treatment of described cup has bidirectional relief valve, between right-hand member joint and bidirectional relief valve, is provided with seal washer, and bidirectional relief valve is also provided with exhaust outlet.
The beneficial effects of the utility model are: adopt the solar water heater liquid level display of said structure, the air of solar water heater built-in heat exchanger can be discharged through overflow pipe, bidirectional relief valve along with adding of circulatory mediator.When normal use, in the time that circulating thermal medium temperature raises generation expansion, circulating thermal medium enters in cup through overflow pipe extruding, the Bas Discharged in cup; In the time that circulating thermal medium temperature reduces generation contraction, utilize siphonage, the circulating thermal medium of cup bottom is sucked to built-in heat exchanger by overflow pipe, cup top automatic makeup is charged into into air, thereby ensures that built-in heat exchanger inside does not enter air; In the time that built-in heat exchanger is not discharged circulatory mediator to cup, the circulating thermal medium deficiency of built-in heat exchanger is described, because cup is transparent shell, be easy to observe, thereby can carry out fluid infusion by fluid infusion mouth in time.Therefore, have simple in structure, easy for installation, circulating thermal medium consumption is little, clearly show circulatory mediator quantity to supplement in time, effectively improve the features such as solar water heater heat exchange efficiency.

Below in conjunction with drawings and Examples, the utility model solar water heater is described further with liquid level display.
Fig. 1 is the cross-sectional view of first embodiment of the utility model solar water heater liquid level display.
In figure: 1, overflow pipe, 2, sealing ring, 3, movable joint nut, 4, cup, 5, right-hand member joint, 6, seal washer, 7, bidirectional relief valve, 8, exhaust outlet, 9, upper end oral area.
Detailed description of the invention
As shown in Figure 1, this solar water heater is mainly made up of overflow pipe 1, sealing ring 2, movable joint nut 3, cup 4, bidirectional relief valve 7 with liquid level display; Cup 4 is transparent shell, and upper end oral area 9 is provided with sealing ring 2, and overflow pipe 1 passes from sealing ring 2, and the nearly top of the built-in heat exchanger in solar water heater water tank is inserted in its upper end, and the nearly bottom of cup 4 is inserted in lower end; The right-hand member joint 5 of cup 4 is provided with bidirectional relief valve 7, between right-hand member joint 5 and bidirectional relief valve 7, is provided with seal washer 6, and bidirectional relief valve 7 is also provided with exhaust outlet 8.
Adopt the solar water heater liquid level display of said structure, the air of solar water heater built-in heat exchanger can be discharged through overflow pipe 1, bidirectional relief valve 7 along with adding of circulatory mediator.When normal use, in the time that circulating thermal medium temperature raises generation expansion, circulating thermal medium enters in cup 4 through overflow pipe 1 extruding, the Bas Discharged in cup 4; In the time that circulating thermal medium temperature reduces generation contraction, utilize siphonage, the circulating thermal medium of cup 4 bottoms is sucked to built-in heat exchanger by overflow pipe 1, cup 4 top automatic makeups are charged into into air, thereby ensure that built-in heat exchanger inside does not enter air; In the time that built-in heat exchanger is not discharged circulatory mediator to cup 4, the circulating thermal medium deficiency of built-in heat exchanger is described, because cup 4 is transparent shell, be easy to observe, thereby can carry out fluid infusion by fluid infusion mouth in time.Therefore, have simple in structure, easy for installation, circulating thermal medium consumption is little, clearly show circulatory mediator quantity to supplement in time, effectively improve the features such as solar water heater heat exchange efficiency.
