Description

Technical Field

[0001] The present invention relates to the field of valves, and in particular to a valve for automatically determining whether hot water is provided by a solar water heater. Background Art

[0002] The country vigorously advocates green energy and low-carbon life. Solar water heaters have been widely accepted by the society as a clean energy. At present, solar water heaters can display the temperature value of the water tank and can automatically fill water, but there are still the following problems: it is impossible to make automatic selection between solar water heater water supply and other energy water supply, which will reduce the utilization rate of solar water heaters. The temperature value of the conversion between solar water heater water supply and other energy water supply needs to be adjusted according to the air temperature, the length of the pipeline, and the user's requirements for water temperature. Manual conversion is relatively troublesome, causing some users to give up using solar water heaters that have been installed and debugged normally. Summary of the invention

[0003] To this end, the technical problem to be solved by the present invention is to provide an automatic water supply valve for a solar water heater, which automatically switches to supply water to the solar water heater when the temperature in the water tank of the solar water heater reaches or exceeds a set temperature. The set temperature can be adjusted according to the environment and personal needs.

[0004] In order to solve the above technical problems, the present invention provides an automatic water supply valve for a solar water heater, which is composed of a temperature regulating device and an electric control valve. The temperature regulating device is used to set the temperature value of the water supply of the solar water heater. When the water temperature in the water tank of the solar water heater is greater than or equal to the set temperature value, the temperature regulating device sends a solar water heater water supply signal to the electric control valve. The electric control valve is composed of a controller, a hot water inlet for the solar water heater, a hot water inlet for other heating equipment, and a hot water outlet.

[0005] Furthermore, the temperature regulating device is equipped with a temperature dial and a pointer, the pointer can rotate, and the temperature value on the dial corresponding to the pointer is the water supply temperature value of the solar water heater.

[0006] Furthermore, the temperature control device is equipped with a display device, a touch screen or a keyboard, and the water supply temperature value of the solar water heater can be set through the touch screen or the keyboard.

[0007] Furthermore, when the electric control valve does not receive the water supply signal of the solar water heater sent by the temperature control device, the hot water inlet and the hot water outlet of other heating equipment are connected, and hot water is provided by other heating equipment. When the electric control valve receives the water supply signal of the solar water heater sent by the temperature control device, the hot water inlet and the hot water outlet of the solar water heater are connected, and hot water is provided by the solar water heater.

[0008] Compared with the prior art, the effect of the present invention is positive and obvious. The present invention provides an automatic water supply valve for a solar water heater, which, in conjunction with an automatic water supply system, can realize the automation of the management of the solar water heater. The water supply temperature value of the solar water heater can be adjusted according to the season, the length of the pipeline, and the user's requirements for the water temperature, thereby improving the utilization rate of the thermal energy of the solar water heater, avoiding the inconvenience caused by manual conversion, and being conducive to the promotion and use of solar water heaters. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0010] Figure 1 It is a principle diagram of the automatic water supply valve of the solar water heater of the present invention.

[0011] In the figure: 1. Temperature control device, 2. Controller, 3. Hot water inlet of other heating equipment, 4. Hot water outlet, 5. Hot water inlet of solar water heater. DETAILED DESCRIPTION

[0012] The structure of the present invention is as follows Figure 1 As shown, an automatic water supply valve for a solar water heater is composed of a temperature regulating device 1 and an electric control valve. The temperature regulating device 1 is used to set the temperature value of the water supply of the solar water heater. When the water temperature in the water tank of the solar water heater is greater than or equal to the set temperature value, the temperature regulating device 1 sends a solar water heater water supply signal to the electric control valve. The electric control valve is composed of a controller 2, a hot water inlet 5 for the solar water heater, a hot water inlet 3 for other heating equipment, and a hot water outlet 4.

[0013] Furthermore, the temperature regulating device 1 is equipped with a temperature dial and a pointer, the pointer can rotate, and the temperature value on the dial corresponding to the pointer is the water supply temperature value of the solar water heater.

[0014] Furthermore, the temperature control device 1 is equipped with a display device, a touch screen or a keyboard, and the water supply temperature value of the solar water heater can be set through the touch screen or the keyboard.

[0015] Furthermore, when the electric control valve does not receive the water supply signal of the solar water heater sent by the temperature control device 1, the hot water inlet 3 and the hot water outlet 4 of other heating equipment are connected, and hot water is provided by other heating equipment. When the electric control valve receives the water supply signal of the solar water heater sent by the temperature control device 1, the hot water inlet 5 and the hot water outlet 4 of the solar water heater are connected, and hot water is provided by the solar water heater.

[0016] Before using the solar water heater, the water supply temperature value must be set. When the temperature is low, the hot water pipe is long, and the user has high temperature requirements, the water supply temperature value must be appropriately increased. During the use of the solar water heater, if the temperature in the water tank is greater than or equal to the set water supply temperature value, the system automatically switches to the solar water heater for water supply. Otherwise, it switches to other heating equipment for water supply. The present invention combined with the automatic water supply system can realize fully automatic management of the solar water heater, which is convenient and maximizes the use of the thermal energy of the solar water heater.

[0017] The above is only a preferred embodiment of the present invention. It should be pointed out that as long as the temperature of the solar water heater water supply can be manually set and the solar water heater automatic water supply valve can automatically switch between the solar water heater and other heating equipment, other structural forms are also within the protection scope of the present invention.
