The specific embodiment
For ease of understanding technology contents of the present utility model, below in conjunction with accompanying drawing, it is described further.
A kind of solar water heater winterization system as shown in Figure 1, comprise solar water heater water tank 1, inlet and outlet pipe lines 9, L-type pipe 12, subsidiary conduit 11, auxiliary seal case 2, check-valves 3, valve 1, valve 25, valve 36, valve 47, valve 58, the inside of described solar water heater water tank 1 is stretched in one end of described L-type pipe 12, and this end port is near the bottom of described solar water heater water tank 1, its other end is positioned at the outside of described solar water heater water tank 1, and connecting tee joint.
Described three-way connection connects one end of described check-valves 3 in the horizontal direction, and the other end of described check-valves 3 is connected with described valve 47 by described subsidiary conduit 11, and the other end of described valve 47 is communicated with atmospheric environment; The installation of described check-valves 3 need guarantee that conducting direction is to L-type pipe 12 and inlet and outlet pipe lines 9 by subsidiary conduit 11.
Described three-way connection connects one end of described inlet and outlet pipe lines 9 at vertical direction, the other end of described inlet and outlet pipe lines 9 connects one end of upper end water inlet and the described valve 25 of described auxiliary seal case 2, described valve 25 and auxiliary seal case 2 are for being connected in parallel, the lower end delivery port of described auxiliary seal case 2 is also connected in series described valve 58, at described valve 25, be connected one end of valve 1 and one end of valve 36 with described valve 58 junction ends, described valve 1 and described valve 36 are in parallel, the other end of described valve 1 connects cold water source 10, the other end of described valve 36 connects water jet 13.
In described auxiliary seal case 2, to guarantee to be all the time loaded with the water of certain volume.
Described check-valves 3 is the interface point with described inlet and outlet pipe lines 9 near described L-type pipe 12 preferably.
Described auxiliary seal case 2, valve 1, valve 25, valve 36, valve 47, valve 58, is installed in indoor.
At the interior water level sensor 15 that arranges of described solar water heater water tank 1, described water level sensor 15 connects controller 14, when the depth of water in described solar water heater water tank 1 and described L-type pipe 12 are positioned at the port of one end of solar water heater water tank 1 when equal or reach on this port a certain predeterminated position, described water level sensor 15 just sends induced signal, described controller 14 connects this and is subject to induced signal, and by controlling described valve 1, described valve 25 is realized in described solar water heater water tank 1 and is added water, by controlling described valve 25, described valve 36, described valve 47 is realized after water inlet end, emptying to the water in pipeline.
Non-, freeze season, because do not need the water in pipeline to carry out emptying, do not using when operation, each valve is in closed condition, while needing to add water in described solar water heater water tank 1, by Open valve 1, valve 25 realizations; After adding water, valve-off 1, valve 25; While needing hot water, only need open valve 36, valve 58, it has utilized siphon principle: be specially, because prestore a certain amount of water in described auxiliary seal case 2, open valve 36, valve 58, water in described auxiliary seal case 2 just can flow out, thereby make the inner negative pressure that forms of described auxiliary seal case 2, because the existence of siphonage, water in described solar water heater water tank 1 just can flow into described auxiliary seal case 2 via described L-type pipe 12, described inlet and outlet pipe lines 9, and it uses operation substantially the same with regular solar water heater.
Freezing season, after adding water in described solar water heater water tank 1, each valve is all closed; Open described valve 25, valve 36, valve 47, because described check-valves 3 by subsidiary conduit 11 to L-type pipe 12 and inlet and outlet pipe lines 9 conductings, described opening after valve 47, air enters inlet and outlet pipe lines 9 by valve 47, check-valves 3, again because valve 25, valve 36 are also in open mode, so described inlet and outlet pipe lines 9 is in complete conducting state, thereby by inlet and outlet pipe lines 9 and emptying higher than the water of solar water heater water tank 1 water surface in L-type pipe 12, all anhydrous in the piping outside the house, thus can effectively prevent frost crack pipe; After water in pipeline is emptying, close each valve.When needs hot water, operating process with above-mentioned non-freeze the same during season.Each use after hot water, need to be by method described above, the water in pipeline is carried out emptying, prevents that pipeline internal memory from leaving water, and causes the bursting by freezing of pipeline is damaged.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
