After adopting this structure, the emptying valve can be opened and closed by manual operation, no additional circuit control system is needed, the structure is simple, and the modification is convenient. There is no need to reinstall the electric instrument, two manual emptying valves and a small section of emptying pipe can realize the emptying of the stagnant water in the pipe, which reduces the complicated installation of the solar circuit. At the same time, the manual emptying valve is used instead of the solenoid valve. To a good energy-saving effect, to avoid waste of electric energy.

Place a container for collecting water under the drain tube. After adopting this structure, the discharged water can be followed by the container and recycled.

The principle of the utility model is: when the solar water heater is in use, the first emptying valve is in the normally open state, the second emptying valve is in the normally closed state, and the water flow of the connecting pipe and the outlet pipe is smooth; when the solar water heater is not used for a short time in winter, In order to prevent the outdoor pipes from freezing, it is only necessary to close the first emptying valve and open the second emptying valve to drain the accumulated water in the outdoor pipes, and the discharged water can be recycled; When all the water in the bucket and the outdoor pipeline is discharged, you only need to open the first emptying valve and the second emptying valve until all the water is discharged.

In general, the utility model has the following advantages:

(1) It can prevent the pipeline system of the solar water heater from freezing in winter and ensure the normal use of the solar water heater.

(2) The technology is simple, the transformation cost is low, and the stagnant water inside the pipeline is evacuated by the pipeline emptying method, the operation is simple and easy, and the manufacture is simple.

(3) Compared with the existing anti-freezing technology, it is very energy-saving. The emptying of retained water does not require electric energy, and only needs to control two manual emptying valves.

(4) The discharged water can be recycled.
