Specific implementation mode
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
Shown in Fig. 1-2, a kind of solar water heating system with evacuation and anti-freezing function, including solar thermal collector with
And the hot water storage tank 12 being connected by water lines with the solar thermal collector, the hot water storage tank have water inlet 13 and
Water outlet 11, the water inlet are connect by emptying pump 17 in parallel with blow-down pipe phase 16, and the blow-down pipe passes through first three
Three-way electromagnetic valve is connected with the drainpipe 18 of 7 solar thermal collectors, the other end of first three-way magnetic valve and second
One end of three-way magnetic valve 8 connects, other two ports of second three-way magnetic valve respectively with connect the water outlet
Hot water outlet pipe 9 and connect the hot-water line of water equipment 10 and be connected, the water inlet of the solar thermal collector connect into
Water lines 5 have into water instrument 6 and piping filter 18 on the inlet pipeline.
The water inlet instrument is prior art device, and the control of control solar thermal collector water inlet may be implemented.When need into
When water is to solar thermal collector, water inlet instrument water inlet is opened, a certain amount of closing is arrived in water inlet, and water inlet instrument can be manual water inlet instrument,
Can be automatic feeding water instrument, it is specific unlimited.
Wherein, the solar thermal collector includes glass heat pipe 2 and the header being connect with the glass heat pipe 1, described
Header has water inlet 3, water outlet 4.Superconductive medium is housed in glass heat pipe 2, photothermal conversion, superconduction are carried out by receiving sunlight
Medium flows in glass heat pipe, carries out solution-air conversion, realizes the heat exchange with the water in header to heat water in header, carries out
Prepare hot water.
Wherein, there is temperature sensor 14 on the header, to detect the temperature and breather valve 15 of the water in header.When
When temperature sensor detects that the temperature of the water in header is less than predetermined value, emptying pump startup can be controlled, by the water in header
Be discharged in hot water storage tank store use.
The hot water storage tank, water equipment are vented and pump, and two three-way magnetic valves are set to interior, other to be set to outdoor certainly
In right environment.
When normal use, the hot water of solar thermal collector is converted from first three-way magnetic valve, second three-way magnetic valve
It is formed by access and flows to water equipment 10, when needing emptying, first three-way magnetic valve shutdown and second threeway electromagnetism
Access between valve opens the access of blow-down pipe, and water inlet instrument is closed, and a startup of pump is vented, by header and inlet pipeline, draining
Water in pipe, which is evacuated in hot water storage tank, to be stored, anhydrous in such header and inlet pipeline, drainpipe, so as to avoid external environment
