Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figure 1, the embodiment of the utility model provides a water tank for a solar water heater, including:

Box 1;

The liner 2 for holding water has a first cavity 3, which is arranged in the box body 1 and connected with the box body 1;

The second cavity 4 for containing the medium is arranged between the inner surface of the box body 1 and the outer surface of the liner 2;

The medium inlet 5 is arranged on the box body 1 and communicates with the medium outlet of the heat collecting part of the solar water heater;

The medium outlet 6 is arranged on the box body 1 and communicates with the medium inlet of the heat collecting component of the solar water heater;

The control valve 7 is arranged at the medium inlet 5 and the medium outlet 6 of the tank 1 , and is connected with the medium inlet 5 and the medium outlet 6 of the tank 1 .

Since the medium inlet and the medium outlet of the water tank of the solar water heater provided by the utility model are provided with control valves, once the medium leaks during operation, it is convenient to control; during maintenance, it is convenient for users. Compared with the water tank of the existing solar water heater, the water tank of the solar water heater provided by the utility model is simple to install and convenient to control, maintain and install.

The solar water heater including the water tank provided by the embodiment of the utility model, when working, the heat collecting part absorbs solar radiation, converts light energy into electric energy, and transfers heat to the medium in the heat collecting part, so that the medium with heat passes through and controls the valve 7, the connected pipes flow into the second cavity 3, and after heating the water in the inner tank 2, it is provided to the user. Since the water tank body 1 is provided with a control valve 7 at the medium inlet 5 and the medium outlet 6 communicating with the heat collecting component, such a design ensures that when the medium is in the medium outlet of the solar water heater heat collecting component and the water tank The pipeline connected to the medium inlet of the water tank, the medium connected to the medium outlet of the water tank and the medium inlet of the solar water heater heat collecting part, when circulating in such a circulation loop, once there is leakage, it can be used The control valve 7 is used for control, which is not only convenient for disassembly, assembly and maintenance, but also convenient for users.

As a preferred solution, the control valve 7 is specifically a ball valve. The ball valve is simple in structure, small in size and light in weight. It is not only easy to operate and quick to open and close, but also when it is fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium. When the medium passes through, it will not cause erosion of the valve sealing surface. ,long lasting. Of course, the control valve can also be other types of valves, as long as it can be conveniently controlled when leakage occurs.

As a preferred solution, the control valve 7 may also specifically be a plug valve. The plug valve is quick to open and close, light in weight, small in fluid resistance, simple in structure, relatively small in size, light in weight, easy to maintain, and has good sealing performance. It is not restricted by the installation direction, and the flow direction of the medium can be arbitrary. Of course, the control valve can also be other types of valves, as long as it can be conveniently controlled when leakage occurs.

As a preferred solution, the liner 2 is specifically an enamel liner. The enamel liner can keep the interior clean and hygienic, white and beautiful, and ensure that the water quality is not polluted. Enamel liner, strong and durable, good impact resistance, shock resistance, acid resistance, alkali resistance, corrosion resistance, long service life.
