Abstract
The utility model discloses an anti-freezing device for a solar water heater pipeline and belongs to the technical field of protective devices for the solar water heater pipelines. The anti-freezing device comprises a main pipeline, wherein a water outlet pipe is arranged on the main pipeline which is positioned indoors and is provided with a normally-closed solenoid valve; a normally-open solenoid valve reversing valve is arranged on the top of the main pipeline; an air pipe is arranged at the lower end of the normally-open solenoid valve reversing valve and is higher than the highest water level in a water tank; and a temperature sensor is arranged in the outdoor main pipeline and is controlled to be connected with the solenoid valve reversing valve and the normally-closed solenoid valve respectively. The anti-freezing device can be thoroughly emptied and effectively protect the pipeline from being frost-cracked; the pipeline does not need to be subjected to heat preservation treatment, so that the city aesthetics is not influenced; and the anti-freezing device is convenient to operate and can be automatically controlled after being electrified.
Description
Technical field
The utility model relates to a kind of solar energy water heater pipe protector, especially a kind of pipe defroster of solar water heater.
Background technology
At present, solar energy water heater pipe water discharge technology in winter is solar water heater not one of difficult problem of fine solution, especially northern area as yet all the time; Whenever winter, the residual water in the solar energy water heater pipe will be frozen, and causes frost crack pipe; Make troubles to the user, general solution is to carry out the insulation measure to pipeline now, the expense of so taking a lot of work material; Effect is also bad, has also influenced the attractive in appearance of city to a certain extent.
Summary of the invention
The technical assignment of the utility model is to the deficiency of above prior art a kind of pipe defroster of solar water heater to be provided.
The utility model solves the technical scheme that its technical problem adopted: pipe defroster of solar water heater; Comprise trunk line; Wherein be provided with drainpipe being positioned on the indoor trunk line, on said drainpipe, be provided with normally closed solenoid valve, be provided with the normally open solenoid valve reversal valve at the top end of said trunk line; Lower end at said normally open solenoid valve reversal valve is provided with breather pipe; Said breather pipe is higher than maximum water level in the water tank, in said outdoor trunk line, is provided with temperature sensor, and said temperature sensor links to each other with normally closed solenoid valve with the magnetic valve reversal valve respectively through controller.
Its operation principle is when the water temperature in the temperature sensor measurement trunk line is zero degrees celsius; Controller will control the normally open solenoid valve reversal valve and cut out; The control normally closed solenoid valve is opened, and at this moment, the water in the pipeline will flow out through drainpipe under the effect of air pressure and gravity.
The utility model has the advantages that: 1, emptying is thorough, has protected pipeline not by bursting by freezing effectively; 2, need not be incubated processing to pipeline, it is attractive in appearance not influence the city; 3, easy to operate, as long as energising can realize automatic control.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with Figure of description the utility model is done following detailed description.
As shown in the figure; Pipe defroster of solar water heater comprises trunk line 1, wherein is provided with drainpipe 2 on the indoor trunk line being positioned at; On said drainpipe 2, be provided with normally closed solenoid valve 3; Top end at said trunk line 1 is provided with normally open solenoid valve reversal valve 4, is provided with breather pipe 5 in the lower end of said normally open solenoid valve reversal valve 4, and said breather pipe 5 is higher than maximum water level in the water tank; In said outdoor trunk line, be provided with temperature sensor 6, said temperature sensor 6 links to each other with normally closed solenoid valve 3 with normally open solenoid valve reversal valve 4 respectively through controller.
