About tyre valve introduction
The tyre valve is a one-way valve that fills the gas in the tire and maintains the pressure in the tire. Today, tires used in automobiles are all liner-free tires.Tyre valves and tires are separated from each other on the structure. Tyre valves are installed on the rim to play its role.

Tyre valves are small, but they can be divided into valve bodies (bases), gaskets, gaskets, fastening nuts, tyre valve cores, and tyre valve caps, all of which are also structural. Has its own role. (Taking a metal valve as an example)
The tyre valve body (base) is the only way for the gas to enter the tire, and at the same time accommodates and protects the tyre valve core. From the name, the fastening nut knows that its role is to make the valve and wheel ring more stable; The gaskets of different materials are used to fasten the fastening nuts; the rubber gaskets seal the inside of the rim to prevent air leakage; the valve caps that are often lost can avoid the intrusion of foreign objects on the valve nozzles. The secondary sealing of the valve is achieved, and the valve core has the function of preventing the gas from leaking out while ensuring that the gas is smoothly injected into the tire.
