The specific embodiment
Embodiment 1:
The solar water heater of the present embodiment, as Fig. 1, for the setting of heat collector 2 higher than boiler 3, comprise heat collector and boiler, between described heat collector and boiler, be communicated with hot-water line and circulation pipe, described hot-water line is communicated in top or the top of an end and the described boiler of described heat collector, described circulation pipe is communicated in bottom or the bottom of the other end and the described boiler of described heat collector, described circulation pipe is equipped with forced circulation pump, described forced circulation pump is parallel with and flows back to device 4, and the described device 4 that flows back to is electrically operated valve.
When solar water heater is in that noon sunlight weakens or weather is turned out cloudy, water temperature in heat collector 2 no longer rises, while even starting to descend, the temperature difference flows back to device 4 and opens, due to the impact that is subject to gravity, the water of heat collector 2 internal ratio higher temperatures flows back in boiler 3 automatically, takes full advantage of the hot water in heat collector 2.
As the user when using solar water heater, when the water storage of boiler 3 is not enough to meet user's demand, forced circulation pump 1 just can be opened, and the water in the water that does not meet design temperature in heat collector 2 and boiler 4, by recycle loop, is reached and meets the demand of water in short-term.
The solar water heater of the present embodiment also comprises pressure-reducing valve 5, and described pressure-reducing valve 5 series connection are arranged on described cold water source pipeline.By pressure-reducing valve 5 is set, can guarantee that cold water (running water) enters the pressure that the stable water pressure in heat collector 2 and the system that is less than can bear, and prevents the excessive damage solar thermal collector 2 of hydraulic pressure.
The solar water heater of the present embodiment also comprises pressurization heat supply water pump 6, and described pressurization heat supply water pump 6 is arranged between described boiler 3 and described user side.When boiler 3 hydraulic pressure not maybe can not meet the user to the demand of hydraulic pressure, pressurization heat supply water pump 6 can provide required hydraulic pressure for the user.
Also comprise air inlet-exhaust valve 8, as Fig. 3, comprise tube connector 81 and swing check valve 82, what described tube connector 81 was communicated in described solar thermal collector flows to fluid media (medium) pipeline 21, and is positioned on the high position of described solar thermal collector; Described check-valves 82 is installed on described tube connector 81, and the position that described tube connector 81 is installed described check-valves 82 is 45 ° and is in tilted layout, and the permission flow direction of described check-valves 82 is to described heat collector 2 from described tube connector 81.
Solar thermal collector is when normal heat absorption, water in heat collector 2 can constantly discharge the air in being dissolved in water in the temperature elevation process, due to the impact that is subject to the sinking of hot water floating cold water, air and partially liq flow to the upper end of heat collector 2, gaseous volatilization in water is discharged by check-valves 82 by tube connector 81, and check-valves 82 is obliquely installed, and is subject to the effect of gravity, make the blade of swing check valve 82 keep semi-open state, have space that gas is discharged in atmosphere by check-valves 82; When need to be by the delivery that has been heated to predetermined temperature in heat collector 2 in boiler the time, start water pump, the pressure of the water in heat collector 2 increases, tend to discharge by tube connector 81, existence due to check-valves 82, can stop water to be discharged from tube connector 81, this has just guaranteed that tube connector 81 both can exhaust, can stop again water to flow away since then, venting and the automatic effect that stops current to pass through that check-valves 82 adopts 45 ° arrange can make check-valves 82 are more balanced, and it is best that two aspect performances all reach; Also include buffering water pot 83, the end of described tube connector 81 is communicated with buffering water pot 83, when the existence of buffering water pot 83 makes heat collector 2 pumping hot water, check-valves 82 had little time to seal and some current of spilling also can store in just incipient stage, when water pump quits work, the water of buffering in water pot 83 can automatic back flow in heat collector 2; Described buffering water pot 83 is airtight container, the top of described buffering water pot 83 is provided with the suction tracheae, because heat collector 2 generally is positioned over roof, dust is larger, 83 sealings of buffering water pot make water cleaner, the water overflowed is stored in buffering water pot 83, and the gas of discharge is discharged by the suction tracheae through buffering water pot 83; By this air inlet-exhaust valve 8, take to design cleverly, exhaust and air-breathing two functions are fused in the middle of a device, result of use is good, and fault is low, installation is attractive in appearance, overcomes and solved the problem of current solar water heating system and other hot-water heating system air intake and exhaust system.
Embodiment 2:
The solar water heater of the present embodiment and embodiment's 1 is basic identical, as Fig. 2, when heat collector 2 with boiler 3 when same level is even low, the temperature difference flows back to device 4 and is a small pump, water in thermal-arrest 2 can be extracted in boiler 3, simultaneously in forced circulation pump 1 water inlet, be provided with motor-driven valve 7, motor-driven valve 7 cuts off in the temperature difference, flowing back to when device 4 starts the pipeline that boiler 3 bottoms are connected with heat collector 2.
Finally should be noted that; above embodiment is only be used to the technical solution of the utility model is described but not to the restriction of the utility model protection domain; although with reference to preferred embodiment, the utility model is explained in detail; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement the technical solution of the utility model, and not break away from essence and the scope of technical solutions of the utility model.
