Technical Field

[0001] The utility model relates to the technical field of waterway valves, in particular to a panel-type water valve. Background Art

[0002] At present, countless households suffer from water leakage accidents every year, most of which are serious water leakages caused by long-term unattended homes.

[0003] Many modern home renovations include the installation of a main water valve indoors to facilitate future pipe replacements and water shut-off. There are two main types of main water valves commonly used: ball valves and globe valves. Ball valves are surface-mounted, while globe valves are concealed, typically installed under kitchen cabinets.

[0004] According to the living habits of most people, they often turn off the electricity before going out, but they don't have the habit of turning off the water. The reason is not that they don't remember to turn off the water, but that the water valves are not designed for the owners to be easy to operate.

[0005] Some users don't know how to turn off existing water valves. Some women struggle to turn the handle on ball valves, especially those that haven't been used for a long time. Some stop valves are half-open, and users can't tell whether to turn them left or right. In emergencies involving water leaks, shutting off the water often requires assistance from property management, which takes up staff time and can delay repairs.

[0006] Most homes nowadays install a main lighting power switch, living room light switch, and hallway light switch at the entrance to facilitate on / off operation when entering and leaving the house. However, to date, no manufacturer has designed a main water valve (main water valve) that is as convenient as a lighting power switch for on / off operation when entering and leaving the house.
