Water injection automatic closing device for solar water heater

Abstract

The invention discloses a water injection automatic closing device for a solar water heater. A solar water tank is connected with a water inlet pipe (1) and a water return pipe (3). A water valve is arranged on the water inlet pipe (1). The automatic closing device comprises a closing cavity (4) formed in a pipeline of the water inlet (1). A closing steel ball (6) is arranged in the closing cavity (4). A stop piece matched with the closing steel ball (6) is arranged on the inner wall of the closing cavity (4). A water pot (7) is arranged outside the closing cavity (4) and connected with the closing cavity (4) through a rope (10). A magnet (8) used for attracting the closing steel ball (6) is arranged on the top of the water pot (7). A siphon (9) used for leading out water is arranged in the water pot (7). The water return pipe (3) is communicated with the water pot (7). The closing steel ball is broken away from attracting force of the magnet through the gravity of water and is matched with the stop piece inside the closing gravity, and therefore a water injection passageway is closed, and water resource waste is avoided.

Description

Technical field [0001] The present invention involves the field of solar water heaters, which is specifically a automatic turnover device of solar water heater water injection. Background technique [0002] The solar water heater is increasingly adopted due to the advantages of convenient use and environmental protection and energy saving. The current solar water heaters are generally manually opened the water valve on the water inlet pipe to pour water in the solar water tank. After the water tank is full, the water tank is full.Water overflows from the water return pipe, and whether the user overflows the water from the water back pipe to determine whether the water of the water tank is full. In many cases, the user will forget to close the water valve, causing the water resources to waste. Invention content [0003] The purpose of the present invention is to provide automatic turbide device of the solar water heater water injection. The interrupt device can automatically turn...

Problems solved by technology

[0002] It is well known that solar water heaters are more and more used by people due to their advantages of convenient use, environmental protection and energy saving. The current solar water heaters generally manually open the water valve on the water inlet pipe to fill the solar water tank. After the water tank is full, The water overflows from the return pipe, and the user judges whether the water tank is full by whether there is water overflowing from the return pipe. In many cases, the user will forget to close the water valve, resulting in a waste of water resources
