Example Embodiment

[0011] Example one, such as figure 1 As shown, it is a push-pull valve stem type solar water heater water supply valve, from figure 1 It can be seen that it includes a water supply valve body 1, a water wheel rotation mechanism is installed on the water channel of the water supply valve body 1, and a lever push mechanism is installed on one side of the valve body. The water wheel push mechanism is composed of a water wheel. 7. A set of reduction transmission gears 3, 4, 5 and 6 and cam 12 are composed. The lever pushing mechanism is composed of a lever 10 and a spring 14. The fulcrum of the lever 10 rests on the valve stem 9 of the water supply valve, and the valve stem 9 is installed in the valve sleeve 2 of the water channel. The fixed end 8 of the lever 10 is hinged on the valve body 1, and the movable end 13 of the lever 10 is pulled by the spring 14 and pressed against the cam 12. There is a dial 11 on the cam 12, and the amount of water or the rotation angle of the cam can...

Example Embodiment

[0012] Example two, such as figure 2 As shown, it is a spool-rotating solar water heater filling valve. Its structure is the same as that of the first embodiment, except that there is a corner type filling valve handle 15, which rests on the lever 10, which is driven when the lever 10 rebounds. The valve stem 9 rotates to automatically close the water stop valve.

Abstract

The application discloses a water feeding valve for a solar water heater. The water feeding valve comprises a water feeding valve body and is characterized that a water wheel rotating mechanism is mounted at a water channel of the water feeding valve body and a lever pushing mechanism is mounted on one side of the valve body. The water wheel pushing mechanism is provided with a water wheel, a reduction driving gear and a cam. The lever pushing mechanism has the structure as follows: a fixed end of a lever is hinged with the valve body; a free end is drawn by a spring to push against the cam; and a supporting point of the lever is leaned against a valve stem or a rotating handle of the water feeding valve. When water is fed to the solar water heater by utilizing the invention , the water feeding valve can be automatically closed even though the valve is forgotten to be closed, thereby preventing tap water from spilling over in a large amount, and saving the water.

Description

technical field [0001] This application relates to solar water heaters. Background technique [0002] At present, solar water heaters have become popular. It is generally installed on the roof of the building, and the water supply pipe leading out of the toilet is connected to the solar water tank, and the water supply valve or the integrated water supply valve is set on the water supply pipeline. This water supply valve all relies on manual opening, and manual closing, once opening forgets to close, will cause tap water to overflow from solar water heater ceaselessly, waste water resource, even cause flood. Contents of the invention [0003] The purpose of this application is to solve the problem that the water supply valve of the solar water heater cannot be closed automatically, and to design a water supply valve of the solar water heater with the function of automatic closing. [0004] In order to achieve the above-mentioned purpose, the structure of the present appl...
