The principle of the common bicycle valve

The principle of the common bicycle valve

Answer:

When the air pump does not inflate, the elastic rubber tube is tightened to cover the small holes on the side, so that the air can not flow back from the tyre.
An elastic thin edge hose is placed below to form the whole of the core. In fact, it is a one-way valve. When inflating the bicycle tyre, the compressed air in the air pump enters the valve core from the hollow part, and the elastic rubber tube is top, and the air enters the tyre.
The main body of the valve core is a small upper end hollow and solid cylinder at the lower end, and a small hole is opened at the lower end of the lower end to connect with the hollow part.
The diode is powered by single items. The bicycle valve is single - ventilated. Basically, a rubber is wrapped over the valve coreThe rubber is wrapped in the long, thin hole under it
