Yang Yuanfa, 52, looks like an old naughty boy.

Yesterday, the science and technology enthusiast showed 3 inventions, one of which was an environment-friendly shoe cover.

This comfortable, environmentally friendly and durable cloth shoe cover is designed according to the shape and size of shoes.

The second works of < p > < a href= "http://sjfzxm.com/news/index_cj.as > > Yang Yuan FA < /a > are automatic water storage emergency water stop devices for tap water.

"This device adopts a one-way sealing non-toxic rubber valve, which is fixed with screws, so that water can only enter and can not go out and store water in the water tank."

Yang Yuanfa introduced that the size of the water tank can be determined according to the requirements. The water level (water) scale marked by a pparent rubber tube or glass tube is installed on the outside of the water tank.

The higher the water tank is, the greater the pressure of emergency water will be.

At the top of the tank, one way sealing non poisonous rubber valve is also used as the exhaust port. When the water is filled, the exhaust hole can be automatically sealed to avoid water leakage.

When the tap water is stopped, the one-way sealing valve can automatically seal, and will not reduce the backflow due to the water pressure. "When the water is stopped, when we start to use emergency water, the water stored in the water tank will flow out, and the water pressure will decrease, automatically opening the exhaust holes above. Under the action of atmospheric pressure, the water will flow out of the water tank for emergency use."
