Abstract
Provided is a pipeline freeze protection device of a solar water heater. The pipeline freeze protection device of the solar water heater aims to keep the interior of a pipeline be in a state without water frequently and prevent the pipeline from freezing and being blocked. The pipeline freeze protection device of the solar water heater comprises a liquid floating ball, an overflow tube, a water storage tank, a main electromagnetic valve, an air inlet electromagnetic valve, a t-branch tube, a water outlet electromagnetic valve, a water outlet tube, a water inlet electromagnetic valve and a tap water tube. The tap water tube is connected with the water inlet electromagnetic valve; the water outlet electromagnetic valve is connected with the water outlet tube; the water inlet electromagnetic valve and the water outlet electromagnetic valve are connected together through the t-branch tube. The air inlet electromagnetic valve, the main electromagnetic valve and the water storage tank are all connected with the t-branch tube; the liquid floating ball is installed at the corresponding position inside the water storage tank, and the overflow tube is arranged at the corresponding position outside the water storage tank.
Description
Technical field
The utility model relates to a kind of solar energy water heater pipe device of not being afraid of frozen block
Background technology
The solar water heater using is at present in the cold raw pipe freezeup phenomenon of seasonal prevalence of freezing, and the facility that need to thaw helps to thaw, and wastes time and takes electricity.Although some pipelines have been dressed a corpse insulation material, but often there is pipe freezeup situation.
Summary of the invention
The utility model object overcomes above-mentioned the deficiencies in the prior art exactly, provides in a kind of pipeline and often keeps anhydrous state, is not afraid of the solar energy water heater pipe device of frozen block
The utility model comprises: liquid ball float, overflow pipe, storage tank, total magnetic valve, air inlet electromagnetic valve, three-way pipeline, go out water solenoid valve, outlet pipe, entering water electromagnetic valve, running water pipe.Running water pipe is connected with entering water electromagnetic valve, goes out water solenoid valve and is connected with outlet pipe, entering water electromagnetic valve and go out water solenoid valve and coupled together by three-way pipeline.Air inlet electromagnetic valve, total magnetic valve, storage tank all interconnect with three-way pipeline; Relevant position in storage tank is provided with liquid ball float, outside corresponding positions is equipped with overflow pipe.
During use, each magnetic valve status is: entering water electromagnetic valve is closed, go out water solenoid valve and open, and total closed electromagnetic valve, air inlet electromagnetic valve is closed.When needs are gone up water, close out water solenoid valve, open entering water electromagnetic valve and total magnetic valve, start upper water: when water storage tank water level acquires a certain degree, liquid-level floater floats, and control and close entering water electromagnetic valve and total magnetic valve, stop upper water; Then open out water solenoid valve, air inlet electromagnetic valve carries out backwater; After backwater, close air inlet electromagnetic valve.When needs water, open total magnetic valve, hot water through going out water solenoid valve, outlet pipe flows back to indoor; While stopping water, close total magnetic valve, open air inlet electromagnetic valve and carry out backwater; After backwater, close air inlet electromagnetic valve.
We know, the key reason of pipe freezeup is in pipe, to have water.The utility model is to utilize backwater principle, thereby the interior anhydrous state of holding tube reaches the object of not being afraid of frozen block often.Because always magnetic valve and air inlet electromagnetic valve, near this thermal source of storage tank, need the position of insulation very little, so the probability of frozen block is very little.Even frozen block, the position that need to thaw also seldom.
Accompanying drawing explanation
Figure is the utility model structural representation.
In figure: 1, liquid ball float, 2, overflow pipe, 3, storage tank, 4, total magnetic valve, 5, air inlet electromagnetic valve, 6, three-way pipeline, 7, go out water solenoid valve, 8, outlet pipe, 9, entering water electromagnetic valve, 10, running water pipe.
The specific embodiment
The utility model can be controlled by integrated circuit the unlatching of each magnetic valve.During the Position Design of total magnetic valve and air inlet electromagnetic valve, as far as possible near storage tank, the segment pipe between total magnetic valve and storage tank need to be dressed a corpse insulation material.
