The function and composition of the tire valve:
The function of the valve is to inflate and deflate a tire, a small part, and to maintain the tire after the inflation of the seal. The common valve is composed of three main parts: valve body, valve core and valve cap.
Classification of tire valves:
As the most common material valve, the lower cost of rubber valve is widely assembled on the original wheel hub, and the cost of replacement is very low. However, due to the inevitable aging of rubber materials, valve valve body will gradually crack, deformation, loss of elasticity. And when the vehicle driving, the rubber valve will also sway back and forth with the centrifugal force deformation, which will further promote the aging of rubber.
2. Steel valve
In order to avoid the aging problem of rubber valve, metal valve gradually appeared on the market, and steel valve is one of them. As a result of material changes, steel valve valve prices than rubber valve to much higher. Steel valves last two to three times as long as rubber ones, thanks to the fact that the metal is less prone to oxidation and has better air tightness. However, the weight of steel valve is aluminum, rubber, steel valve of these three materials in the heaviest, the total weight of four steel valve reached 150g. Considering the dynamic balance of the tire, the installation of steel valve needs to install more weight on the hub, which will increase the vehicle's mass under the spring.
3.Aluminum alloy valve
Aluminum valve nozzle is also a metal valve nozzle, its service life and air tightness and steel valve comparable, but the price is generally more expensive than steel valve, which is mainly because aluminum alloy is lighter than steel weight, this is undoubtedly more beneficial to the dynamic balance of the wheel. But if you buy a poor-quality aluminum alloy used for a long time may rust, if the rust, screw can not be opened, the force may be broken.
4. A valve port with a TPMS
This type of valve is combined with tire pressure monitoring. So it is also the most expensive.
