Detailed description of the invention

It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.

Fig. 1 shows the structural representation of the embodiment mono-of solar-heating device of the present utility model, and as can be seen from the figure, the solar-heating device of the present embodiment comprises heat supplying loop and pressure regulation circuit.Wherein, pressure regulation circuit is connected with heat supplying loop, to regulate the pressure in heat supplying loop.By pressure regulation circuit, the pressure of heat supplying loop is regulated, can make to keep suitable pressure in heat supplying loop, to guarantee that circulatory mediator circulation time in pipeline overcomes the resistance that pipeline brings, guarantee the smooth and easy circulation of circulatory mediator in pipeline.

Above-mentioned heat supplying loop comprises heat collector 1 and safety valve 1a, and heat collector 1 has liquid outlet, liquid return hole and pressure relief opening, and wherein, safety valve 1a is connected with pressure relief opening.It is the parts because of the collection heat of heat collector 1 in heat supplying loop that pressure relief opening is opened on heat collector 1, and its temperature has a greater change with the fluctuating tool of external environment, thereby makes the inside of heat collector 1 have larger pressure variation.In the time that the pressure in heat supplying loop exceeds the first predetermined value, can spray the circulatory mediator in heat supplying loop from pressure relief opening and safety valve 1a, to reduce the force value of heat supplying loop.

Along with the rising of the pressure in heat supplying loop, the boiling point of circulatory mediator also can be improved accordingly.In the time maintaining higher pressure in heat supplying loop, the heat that circulatory mediator portability is more, heat capacity and the heating efficiency of raising solar-heating device.Especially in the lower region of air pressure, only make the normal use of the certain force value guarantee solar-heating device of the interior maintenance of heat supplying loop.

Above-mentioned pressure regulation circuit has the first pressure and regulates mouth and second to regulate mouth, and the first adjusting mouthful is passed through safety valve 1a and is connected with pressure relief opening, and second regulates mouth to be connected with the liquid return hole on heat collector 1.Can enter into pressure regulation circuit from the circulatory mediator of pressure relief opening and safety valve 1a ejection.When the pressure in heat supplying loop is during lower than the second predetermined value, circulatory mediator regulates mouthful by the second pressure and liquid return hole returns in heat supplying loop, to promote the pressure in heat supplying loop, makes the pressure of heat supplying loop meet the demand that circulatory mediator moves.

Pressure regulation circuit comprises the retracting device 11, fluid reservoir 12 and the pressuring pump 13 that connect successively.Wherein, retracting device 11 is for collecting the circulatory mediator from safety valve 1a ejection, and these these circulatory mediators is stored in the fluid reservoir 12 in downstream.13 of pressuring pumps can be suppressed back the circulatory mediator of fluid reservoir 12 interior storages in heat supplying loop, increase the pressure of heat supplying loop.Reflux for preventing that circulatory mediator produces in the process of suppressing, between pressuring pump 13 and the second pressure adjusting mouth, be also provided with check-valves 14, so that circulatory mediator can only carry out one-way flow.Between check-valves 14 and the second pressure adjusting mouth, be also provided with hand-operated valve 15, when pressure regulation circuit maintenance to facilitate, manually block the media flow in pressure regulation circuit.
