Description
Technical field
The utility model belongs to the technical field that reproducible clean energy resource utilizes, and relates to the structure of solar vacuum heat-collecting pipe water heater.More particularly, the utility model relates to a kind of solar water heater solar heat protection aqueous reflux structure.
Background technology
At present, solar water heater is widely used in vast town and country, and with regard to energy savings and environmental protection, its advantage is very obvious.
But general solar vacuum heat-collecting pipe water heater is for simplified structure, on running water water inlet and hot water discharge water the structure of pipeline, employing be same pipeline, watering pipeline is set no longer separately.Adopt a water water valve to discharge water, and carry out the mixing of hot and cold water with cold water water valve and hot water water valve.By the aperture of control cold water water valve and hot water water valve, the proportioning of control hot and cold water is regulated water temperature.After water finishes (in fact also having a large amount of hot water in the water tank), close the water water valve; Open cold water water valve and hot water water valve simultaneously, utilize the hydraulic pressure of running water, replenish running water to water tank.
This will produce a problem: when tap water cut-off or hydraulic pressure were not enough, the hot water in the water tank can flow in the pipeline of running water by water pipe and cold water water valve, hot water water valve, produces hot water refluence phenomenon.This phenomenon all might take place at any floor, because the water tank height is certain, flows backwards as long as the hydraulic pressure of running water, all can produce hot water less than the pressure of water tank.The user generally there is no fear of noticing this phenomenon.Only relatively more careful user, whether when water tank replenishes cold water, it is hot to remove to touch running water pipe with hand., and normal when just having begun sometimes, the hydraulic pressure of running water descends subsequently, and this just more is difficult to find.Controlling the hot water refluence concerning the user artificially is difficult to accomplish.Therefore, should take measures necessary technically.
The utility model content
Problem to be solved in the utility model provides a kind of solar water heater solar heat protection aqueous reflux structure, its objective is to prevent when water tank replenishes running water, produces the hot water refluence because the hydraulic pressure of running water descends.
To achieve these goals, the technical scheme taked of the utility model is:
This solar water heater solar heat protection aqueous reflux structure provided by the utility model, comprise water inlet pipe and water outlet pipe, return pipe, on water inlet pipe and water outlet pipe, be positioned at user's use location, establish hot water water valve and cold water water valve successively by water tank to running water pipe direction, the water inlet end of described cold water water valve is communicated with running water pipe, between hot water water valve and cold water water valve, be connected with the water water valve by threeway, on the running water pipe outside the water inlet end of described cold water water valve, check valve is set, and the conducting direction of described check valve is identical with running water proper flow direction.
Described water inlet pipe and water outlet pipe and return pipe close up and distribute and outside water inlet pipe and water outlet pipe and return pipe suit water pipe sheath.
The utility model adopts technique scheme, can prevent the refluence of hot water to running water pipe on the basis that discharges water with the shared water pipe of last water, can not cause the waste of hot water, and is simple in structure, effective; Realize the insulation of water pipe easily.
Description of drawings
Below expressed content of this Figure of description and the mark among the figure are briefly explained:
Fig. 1 is a structural representation of the present utility model.
Be labeled as among the figure:
1, water tank, 2, water inlet pipe and water outlet pipe, 3, return pipe, 4, the hot water water valve, 5, the water pipe sheath, 6, breather pipe, 7, the cold water water valve, 8, the water water valve, 9, check valve, 10, running water pipe.
The specific embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and operation principle, the manufacturing process of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
The of the present utility model structure expressed as Fig. 1, the utility model is a kind of solar water heater solar heat protection aqueous reflux structure, comprise water tank 1, water inlet pipe and water outlet pipe 2, breather pipe 6, return pipe 3, on water inlet pipe and water outlet pipe 2, be positioned at user's use location, establish hot water water valve 4 and cold water water valve 7 successively by water tank 1 to running water pipe 10 directions, the water inlet end of described cold water water valve 7 is communicated with running water pipe 10, is connected with water water valve 8 by threeway between hot water water valve 4 and cold water water valve 7.
Water inlet pipe and water outlet pipe 2 discharges water when being used to use, and after using up on the pipeline used of water.Its water inlet is located at the intracavity bottom of water tank.The effect of return pipe 3 is when last water, by outside spilling water, sends the full signal of water tank.The effect of breather pipe 6 is in use, plays the air inlet effect, and is badly damaged otherwise casing can be subjected to that the effect of negative pressure is shunk.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, realization prevents when water tank replenishes running water, produces the goal of the invention of hot water refluence owing to the hydraulic pressure of running water descends, the technical scheme that the utility model is taked is:
As shown in Figure 1, this solar water heater solar heat protection aqueous reflux structure provided by the utility model, on the running water pipe 10 outside the water inlet end of described cold water water valve 7, check valve 9 is set, the conducting direction of described check valve 9 is identical with running water proper flow direction.
Adopt technique scheme, can on the basis that discharges water with the shared water pipe of last water, prevent the refluence of hot water, can not cause the waste of hot water to running water pipe, simple in structure, effective; Realize the insulation of water pipe easily.
When last water, if tap water cut-off, or the tap water drops, the hydraulic pressure of the hot water of water tank the trend that hot water flows backwards to running water pipe 10 occurs, at this moment greater than tap water hydraulic, check valve 9 is owing to the effect of its valve core spring, and valve port is closed, and stops the refluence of hot water to running water pipe 10.
In order to realize the good insulation of water inlet pipe and water outlet pipe 2 and return pipe 3, water inlet pipe and water outlet pipe 2 described in the utility model and return pipe 3 close up and distribute and outside water inlet pipe and water outlet pipe 2 and return pipe 3 suit water pipe sheath 5.
Be provided with the insulation packing material in the water pipe sheath 5, and fill up in water inlet pipe and water outlet pipe 2, return pipe 3 and outer and the formed space of water pipe sheath 5 inwalls.
Adopt the insulation packing material that the space in the water pipe sheath 5 is filled, make its rounding, can be not loose, and can increase insulation effect.The insulation packing material generally can adopt glass cord or mica braid over braid to fill.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
