When turning on the water heater during bathing, it is necessary to let go of some cold water in the water pipe, which is both wasteful and inconvenient. Yesterday, I learned from the Wuhan Association for Science and Technology that the water-saving valve invented by a high school student in Wuhan can make a drop of cold water in the water outlet pipe.
The inventor of the water-saving valve is Fang Xiaotong, a girl from Wuhan No. 6 Middle School. In an interview with reporters, she said that in the ordinary water heater outlet pipe, there is some cold water stored, which must be let go. The water-saving valve she invented was installed at the junction of the water heater and the pipe. A two-way rotating motor is attached to the water saving valve. Press the red switch and the motor rotates to open the water saving valve and the hot water flows out along the pipe. Press the green switch once, the motor will rotate for a short time, the water saving valve will be closed, the hot water will stop, and the hot water in the water pipe will be completely discharged.
Fang Xiaotong’s teacher Zhu Hong introduced that the installation of the water valve is relatively low cost and has a strong promotion value.
