The pipeline freezing-proof device is connected with a water inlet and outlet (a same pipe opening) of a hot water storage tank of the solar water heater; the lower part of the pipeline freezing-proof device is connected with a cold water valve and a hot water valve by the outdoor pipeline and a pipeline connected with the outdoor pipeline; the upper part is determined whether to communicate with atmosphere by the valve of the outdoor pipeline freezing-proof device. The utility model has the advantages of simple structure, easy fabrication, reliable work, low cost and good freezing-proof effect.
Description
The utility model relates to a kind of Application of Solar Energy technology, especially a kind of domestic solar water heater outdoor pipe defroster.
Domestic solar water heater is one of the most universal product of application of solar.Though heat pipe water heater, vacuum tube water heater, the freeze proof water heater of structure etc. solve the problem of the preventing freeze in winter of solar water heater's equipment own better, the antifreeze problem of outdoor pipe is failed fine solution.Addressing this problem the way of in the past taking is to select the heat-barrier material insulation thicker, that thermal conductivity factor is littler or adopt electric heating to mix the way of pipe and automatic emptying.First method often needs to increase the expense that is used to be incubated, and is not very effective when weather is terribly cold; Second method is wanted consumed power, increases initial cost and operating cost; The third way is a system complex, and investment was lost efficacy more greatly and usually.
The purpose of this utility model is to provide the domestic solar water heater outdoor pipe defroster of a kind of simple in structure, easy to process, reliable operation, cheap, good freezing protection effect.
The purpose of the utility model can realize by following measure:
A kind of domestic solar water heater outdoor pipe defroster is to be made of pipe defroster, pipe defroster and solar water heater thermal storage water tank's intake-outlet (the same mouth of pipe) links, the bottom of pipe defroster reaches the pipeline and the hot water or cold water's valve that link with outdoor pipe by outdoor pipe and links, and whether its top communicates with atmosphere by the valve decision of outdoor pipe defroster.
The utility model has following advantage compared to existing technology:
The utility model is equipped with by-pass valve control in its high-order bit, and a side and the water heater thermal storage water tank of outdoor pipe defroster link, and its top can communicate with atmosphere or is isolated.It makes pipe defroster and atmosphere link up the emptying that realizes water heater outdoor pipe water according to the unlatching of the height by-pass valve control of temperature, reaches the antifreeze purpose of solar water heater's outdoor pipe.Simple in structure, easy to process, reliable operation of the present utility model, cheap, good freezing protection effect.
Concrete structure of the present utility model is provided by the following drawings:
Fig. 1 is a structural representation of the present utility model
1-water heater thermal storage water tank, 2-pipe defroster, 3-outdoor pipe
4-Cold water tap, 5-hot-water valve
The utility model is also incited somebody to action in conjunction with the accompanying drawings, and embodiment is described in further detail:
With reference to Fig. 1, a kind of domestic solar water heater outdoor pipe defroster, this device is to be made of pipe defroster 2; Pipe defroster 2 is that A point links with water heater thermal storage water tank 1 intake-outlet, and the bottom of outdoor pipe defroster 2 links by outdoor pipe 3 and with 3 pipelines that link and hot water or cold water's valve 4,5, and its top can communicate with atmosphere or completely cuts off by valve 6.
Operation principle of the present utility model is as follows:
In the work of non-heating season joint.Under the normal condition, the valve 6 of outdoor pipe defroster 2 is closed, and does not communicate with atmosphere, is opening hot-water valve 5 (in pipe under the water-filled situation.If be not full of water, can under the situation that sewer pipe 2 is closed, open water supply pipeline 4 water-fillings) moment, the pressure (P that water heater thermal storage water tank 1 intake-outlet A is ordered
0Be atmospheric pressure, the A point is near the water-heater water tank bottom, and overflow pipe and atmosphere are linked up) be: P
A=P
0+ mgh
2And the pressure that the left end C of hot-water valve 5 is ordered is: P
C=P
0+ mgh
2+ mgh
3The pressure of valve right-hand member (linking up with atmosphere) is P
0The pressure differential at two ends, hot-water valve 5 left and right sides for Δ P is like this: Δ P=P
C-P
0=mgh
2+ mgh
3=mg (h
2+ h
3), because h
2+ h
3＞0, so Δ P＞0, under Δ P effect, the hot water among the thermal storage water tank flows out continuously by outdoor pipe defroster, pipeline and hot-water valve 5, and the user can normally use the storage water in the boiler.
When using in the winter time, when opening on the Cold water tap 4 water, close the valve 6 of outdoor pipe defroster 2.Behind the filling up water, the valve of opening on the outdoor pipe defroster 26 communicates with atmosphere, and the pressure that this moment, outdoor pipe defroster 2 B was ordered is: P
B=P
0, the pressure at two ends, the thermal storage water tank A point left and right sides is respectively: P
An A left side=P
0+ mgh
2, P
The A right side=P
0+ mgh
1, because h
1＞h
2So the water of BA section will reflux to the water tank of water heater, till contour with thermal storage water tank's liquid level.Under the situation that hot-water valve 5 is closed, the pressure that C is ordered is: P
C=P
0+ mgh
1+ mgh
3Under the situation that hot-water valve 5 is opened, the pressure at two ends, the C point left and right sides is respectively: P
A C left side=P
0+ mgh
1+ mgh
3P
The C right side=P
0The pressure differential at the two ends, the left and right sides that C is ordered in the pipeline is: Δ P
C=P
A C left side-P
The C right side=P
0+ mgh
1+ mgh
3-P
0=mgh
1+ mgh
3Because (h
1+ h
3)＞＞0 is so water continuously outflows through hot-water valve 5 in the outdoor pipe 3, till emptying.Like this, just reach the freeze proof purpose of outdoor pipe 3 emptyings.Opening and closing except leaning on Artificial Control of the valve 6 of outdoor pipe defroster 2, the temperature that also relies on temperature sensor to measure is controlled, and valve 6 is opened when outdoor temperature is lower than certain value, links up with atmosphere.
Earlier open Cold water tap 4 when using winter, closes the valve 6 of hot-water valve 5 and outdoor pipe defroster 2, makes water heater thermal storage water tank water-filling under running water system pressure; After being full of water, close Cold water tap 4, open hot-water valve 5.During cold weather, as previously mentioned, the water of outdoor pipe can emptying.When using hot water, open Cold water tap 4 earlier and make the pipeline water-filling, and then close Cold water tap 4, open hot-water valve 5, the water of water tank just can use for the user continuously by hot-water valve 5.
