Description

Solar Antifreeze System

technical field

The utility model belongs to the technical field of solar water heaters, in particular to a solar antifreeze system.

technical background

At present, when the upper and lower water systems of known solar water heaters are severely cold in winter, especially in colder regions in the north, the upper and lower water pipes often freeze and block, which affects the use and brings troubles to dealers and users. In order to prevent the water in the upper and lower water pipes from freezing and the water pipes from freezing and cracking, and to ensure that the solar water heater can be used normally in winter, the general antifreeze measures are: 1>. Install electric heating cables on the pipes; 2>. Built-in heating wires in the pipes; 3>. Solenoid valves are installed on the pipes, the pipes are emptied, and the heat pipes conduct antifreeze, etc.; due to the solar water heaters’ upper and lower water pipes, the water is not used for a long time at night, and any heat preservation measures have limitations, resulting in these antifreeze effects. In addition, the use of electric energy for heating requires a 220-volt power supply as an energy source. It is inconvenient to use a power supply during use, and it is time-consuming and expensive, and there is a risk of electrification, and it is not suitable for areas without electricity. Promotional use.

Contents of the invention

The main purpose of this utility model is to overcome the above shortcomings and provide an antifreeze system that can effectively prevent the freezing of solar water heater pipes. electricity, save water resources, and ensure that solar water heaters can still be used normally in the cold north.

The solution to realize the purpose of this utility model is: the solar pipeline antifreeze system includes valves (1), (2), (3), valve core (4), one-way check valve (5), air intake device (6), Air intake pipe (7), main pipe (8), three-way valve (9), water tank (10), water (11); at the outlet of water tank (10), be provided with double pipes (7), (8) , the intake pipe (7) and the main pipe (8) are connected by a three-way valve (9), the main pipe (8) is connected with the tap water pipe, and there is a valve control between the two, the main pipe (8) The outlet is connected with valves (2), (3); a one-way check valve (5) is installed between the air intake pipe (7) and the three-way valve (9), The valve core (4) is installed, the valve core (4) is connected with the provided air intake device (6), and the outlet of the air intake pipe (7) is connected with the valve (1).

When the pipeline system is in normal use, the main pipeline is filled with water, and the water in the intake pipeline reaches the one-way check valve due to the action of the one-way check valve; When empty, use the air intake device to inject gas into the intake pipe from the valve core in the room, the gas pushes open the one-way check valve, and the water stored in the intake pipe from the one-way check valve to the water tank part flows down the pipe at this time Or be pushed back to the water tank, the water in the water tank will no longer enter the air intake pipe due to the continuous influx of gas, open the indoor valve of the air intake pipe, release the water flowing down the pipe, and keep the indoor valve of the air intake pipe open status. Open the indoor valve of the main pipeline. Due to the suction force, the air will open the one-way check valve on the intake pipeline along the intake pipeline and enter the main pipeline through the three-way valve. As the air continues to enter the main pipeline, the water in the water tank Under the action of suction, it gradually becomes smaller and no longer enters the main pipeline until the water in the main pipeline is completely emptied. Since the main pipeline has been emptied, no matter how low the temperature is, the pipeline will not be blocked by freezing.

Compared with the existing upper and lower water pipes of solar water heaters, the utility model has the advantages of simple structure, no need for electric heating, easy to use, not easy to damage, low cost, and more suitable for use in areas without electricity.

Detailed ways

The specific embodiment of the utility model is described in detail below in conjunction with accompanying drawing;

Referring to Figure 1, in the figure 1, 2, 3-valve; 4-valve core, which acts as a one-way check valve, and 5-one-way check valve (or check valve), which mainly functions to prevent water from entering the intake air Pipe, so that there is as much gas as possible and less water in the intake pipe, and it is always in a closed state when there is no external force; 6-inlet device, which can also be used as a pump; 7-intake pipe, used for air intake; 8 -main pipeline, for water circulation; 9-three-way valve; 10-water tank; 11-water.

The solar pipeline antifreeze system includes valves 1, 2, 3, valve core 4, one-way check valve 5, air intake device 6, air intake pipe 7, main pipe 8, three-way valve 9, water tank 10, water 11; The outlet of 10 is provided with double pipelines 7, 8, the intake pipeline 7 and the main pipeline 8 are connected by a three-way valve 9, the main pipeline 8 is connected with the tap water pipeline, and there is a valve control between the two, and the main pipeline The outlet of 8 is connected to indoor valves 2 and 3; a one-way check valve 5 is installed between the air intake pipe 7 and the three-way valve 9, and a valve core 4 is installed in the indoor part of the air intake pipe 7, and the valve core 4 It is connected with the provided air intake device 6 , and the outlet of the air intake pipe 7 is connected with the indoor valve 1 .

The using method of the present utility model is as follows:

When the valves 1, 2, and 3 are closed together, the pressurized gas generated by the air intake device 6 enters the air intake pipe 7 through the indoor valve core 4, and the gas opens the one-way check valve 5, and the one-way check valve 5 To the water stored in the water tank part air intake pipe 7, flow down along the pipeline. Simultaneously, the water 11 of water tank 10 no longer enters in the air intake pipe 7 due to the continuous influx of gas. The water stored in the air intake pipe 7 all flows out through the valve 1, and now the air intake pipe 7 is in an empty state.

When the valve 3 is closed, first open the valve 1, then open the valve 2, when the water 11 in the main pipe 8 flows out through the valve 2, a suction effect is generated, and when the water 11 enters the main pipe 8, the air also passes through the valve 2 After entering the intake pipe 7, the gas opens the one-way check valve 5, and then enters the main pipe 8 through the three-way valve 9, and the air passing through the air intake pipe 7 continuously enters the main pipe 8, and the air in the main pipe 8 The water 11 continuously decreases until the water 11 no longer flows into the main pipeline 8, and the water 11 stored in the main pipeline 8 all flows out through the valve 2, and the main pipeline 8 is also in an empty state at this moment.

When the main pipeline 8 is used normally, the valves 1 and 2 are closed simultaneously, the valve 3 is opened, the main pipeline 8 is filled with water 11, and then the valve 3 is closed, and the valve 2 is opened at this time, and the main pipeline 8 can be used normally (when the main pipeline 8 During normal use, the valve 1 is always closed), if it is cold weather, no matter how low the temperature is, there will be no freezing and blocking in the pipeline, which effectively solves the problem of freezing and blocking the pipeline of solar water heaters in winter.
