Description
[technical field]
The utility model relates to a kind of solar water heater water tank, and particularly a kind of plug-in type connects without the coil pipe solar water heater water tank.
[background technology]
The electron tubes type domestic solar water heater is comprised of related components such as heat dump, water tank, pipeline, valve and support or plate casees.Solar water heater water tank is the container of solar water heater stored hot water, employing be attemperater.Hot water by the endothermic tube collection must store by attemperater, prevents thermal loss.Solar water heater water tank is comprised of inner bag, heat-insulation layer, shell three parts.The fine or not direct relation of heat-insulation layer insulation material heat insulation effect, is even more important in cold season.Heat preserving mode is the insulation of polyurethane integrated foaming process preferably at present.Shell is generally color steel, aluminium plating zinc plate or corrosion resistant plate.
Install coil pipe additional in the water tank of traditional Solar Enercy Fission Geyser, adopt the circulation of ethylene glycol medium double loop, with the indirect mode heat hot water.Ethylene glycol absorbs solar heat in heat dump, rely on thermosyphon circulation, enters in the water tank coil pipe, carries out heat exchange by coil pipe again, sends heat to cold water (as shown in Figure 3).Ethylene glycol needs again a large amount of supplies after long-time loss.Also exist little being leaked in the hot water of ethylene glycol that produces because of poor sealing, weld seam spot corrosion etc., cause the great technical risk of long-term, hidden close and chronic injury human body.
Traditional solar water heater water tank adopts blow-down pipe to get rid of air in the case when adding water.In the straight-through atmosphere of blow-down pipe, make its water tank can not pressure-bearing and become atmospheric water tank.
[utility model content]
The technical problems to be solved in the utility model is not make spent glycol, without coil pipe, adopts direct single loop heat exchange method, provides a kind of plug-in type to connect without the coil pipe solar water heater water tank.
The technical scheme that the utility model technical solution problem adopts is: plug-in type connects without the coil pipe solar water heater water tank, comprises the tank shell with heat-insulation layer, and described tank shell top is provided with the gas bag that raises up; Described tank shell is provided with hot water inlet pipe, hot water outlet pipe and hot water return pipe, wherein said hot water inlet pipe's the mouth of pipe is positioned at described tank shell inner chamber top, described hot water outlet pipe's the mouth of pipe is positioned at described gas bag bottom, and described hot water return pipe is positioned at described tank shell bottom.
As the further improvement of such scheme, described hot water inlet pipe's pipe end coats heat-insulation layer, keeps the temperature difference that inflow temperature is higher than existing water temperature in the case, strengthens the thermal siphon performance of hot-water return, thereby improves the self-loopa ability of whole system.
Another kind as such scheme improves, and described hot water inlet pipe and hot water outlet pipe adopt inserted mode to be installed on the described tank shell.
As the further improvement of such scheme, described tank shell bottom is provided with blow-off pipe, on this blow-off pipe blowoff valve is housed.
Principle of the present utility model is: in tank top gas bag is set, hot water outlet pipe's the mouth of pipe is positioned at described gas bag bottom, and when water tank added water, air was discharged through the hot water outlet pipe; When opening hot water valve and take hot water, the hot water of discharging through the hot water outlet pipe is the high-temperature-hot-water district that takes from tank top.Water tank bottom is equipped with blow-off pipe, can open blowoff valve when needed, gets rid of impurity and ponding in the case, improves the hot water cleannes.
The utility model beneficial effect is: do not make spent glycol, without coil pipe, adopt direct single loop heat exchange method; Because this water tank has gas bag, is convenient to exhaust; Hot water is taken from the tank top high-temperature region, and the hot water temperature of discharging is high, both can provide bath hot water, also can be used as heating hot water, and result of use is good; Can get rid of water tank impurity and ponding, the hot water cleannes are good.

[specific embodiment]
Embodiment 1: referring to Fig. 2, plug-in type connects without the coil pipe solar water heater water tank, comprises the tank shell 1 with heat-insulation layer, and tank shell 1 inner cavity top is provided with the gas bag 2 that raises up; Tank shell 1 is provided with hot water inlet pipe 6, hot water outlet pipe 8, hot water return pipe 7 and blow-off pipe 14, wherein hot water inlet pipe 6 the mouth of pipe is positioned at tank shell 1 inner chamber top, hot water outlet pipe 8 the mouth of pipe is positioned at gas bag 2 bottoms, and hot hot water return pipe 7 and blow-off pipe 14 are positioned at tank shell 1 bottom.Hot water inlet pipe 6 and hot water outlet pipe 8 adopt inserted mode to be installed on the tank shell.
Hot water inlet pipe 6 pipe end coats heat-insulation layer 4, keeps the temperature difference that inflow temperature is higher than existing water temperature in the case, strengthens the thermal siphon performance of hot-water return, thereby improves the self-loopa ability of whole system.
Between heat collector 3 and the horizontal water tank 5, link to each other with hot water return pipe 7 by hot water inlet pipe 6, consist of the single loop of hot water.Serial connection adds water threeway 10 in the middle of the hot water return pipe 7, adds water threeway 10 and is connected with running water pipe by cold water pipe 11, and cold valves 12 and check valve 13 are housed on the cold water pipe 11.
During use, when opening cold valves 12 and hot water valve 9, because tap water pressure is higher than the air pressure of horizontal water tank 5, check valve 13 is opened, and running water adds water by adding water threeway 10 in trend horizontal water tank 5, and air is by hot water outlet pipe's 8 automatic vents.When hot water outlet pipe 8 has running water to flow out, show topped up with water of horizontal water tank 5, close hot water valve 9, enter the sunshine heated condition.
Cold water passes through from heat collector 3, and by sun Multi-stage heating, temperature raises.According to thermosiphon principle, hot water rises along hot water inlet pipe 6, enters horizontal water tank 5.Along hot water return pipe 7, circulation enters heat collector 3 again, is repeatedly heated with multiple stage circulation by the sun again, and temperature further raises.
Because the heat effect of sunshine, heat hydraulic pressure and temperature raise, and are higher than cold water pressure and the temperature of cold water pipe 11.So that check valve 12 is closed and produced the non-return effect, keep hot and cold water pressure reduction.
When opening hot water valve 9 and take hot water, by hot water outlet pipe 8, hot water is taken near the high-temperature region gas bag 2.
Along with the increase of the hot water amount of taking, the heat hydraulic pressure progressively descends.When the heat hydraulic pressure was lower than cold water pressure, check valve 12 was opened, and filler pipe 11 is by adding water threeway 10 on the hot water return pipe 7, to horizontal water tank 5 automatic waterings.Until hot and cold water pressure is when equating, check valve 12 is closed again, automatically stops to add water, enters new round sunshine heated condition.
When in finding hot water, impurity being arranged, close first cold valves 12, and open hot water valve 9 and so that after air might enter horizontal water tank 5, open again blowoff valve 15, manually despumation and ponding.
Embodiment 2: Fig. 3 is the water tank 5 ' of vertical structure, and primary structure and horizontal water tank 5 are similar, and just hot water inlet pipe 6 is transverse tube, and hot water outlet pipe 8 is L shaped bend pipe, and the mouth of pipe is arranged at gas bag 2 tops, and remainder is identical with horizontal water tank 5.
Although illustrated and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that in the situation that does not break away from principle of the present utility model and spirit and can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present utility model is limited by claims and equivalent thereof.
