1. About the function of the valve:
The valve is used to fill and discharge the gas in the tire, and it is a one-way valve that can maintain the air pressure in the tire. Most of the tires used in cars today are linerless tires, and the valve and the tire are structurally separated, and the valve is installed on the hub to play its role.
2. Valves of different materials:
With the application of different materials in all aspects of auto parts, valves are no longer the single rubber material used before, metal materials have been widely used in valves, in the current market, according to demand, Rubber, steel, aluminum alloy, and copper are the most widely used valves.
3. Regarding the installation of the valve:
The assembly method of the valve can be divided into screw-on type, compression type and buckle type. For example, the rubber valve is a snap-on type, and the valve base is equipped with a card slot to facilitate the fixing of the wheel hub, which also leads to its disposable use. Once disassembled, it cannot be used again, but the price is cheap. The metal valve is assembled by twisting, and the valve is fixed by a gasket and a fastening nut, and it can be reused after being removed, but the price is more expensive than the rubber valve.
4. Maintenance and replacement of valves:
As the valves have been working for a long time, they are easily affected by the environment and temperature, resulting in problems such as aging, cracks and breakage, so regular maintenance and replacement are required. In terms of maintenance, the first thing to check is that the valve is sealed well to ensure that the air pressure will not leak. At the same time, it is also necessary to replace damaged or aging valves in time to prevent safety problems. When replacing, choose the appropriate valve according to the tire type and model, and ensure that it is tightly installed with the wheel hub to avoid loosening and air leakage.
In short, the valve is a vital part of the tire, its quality and good condition have an important impact on driving safety and tire life. Therefore, in daily driving, the valve should be checked and maintained regularly to ensure its good condition.
