When you go to maintain your car, I believe you will see a small inflatable port on the tire called a tire valve. Although small in size, its effect is not smaller than that of tires.
The small valve is an important part to guard the gas in the tire. The main function is to inflate and deflate the tire and maintain the seal after the tire is inflated.
In our daily maintenance, the tire valve should also not be ignored. It is best to change the valve regularly to reduce our driving safety hazards.
Because most of the valve material is made of rubber products, there is a problem of aging. If the tire is only changed, and the valve replacement cycle is ignored, the valve is likely to age in advance and increase driving hazards.
Because the valve is made of rubber, it is unavoidable that it will crack, deform and lose its own elasticity.
When the vehicle is driving daily, the rubber valve will swing back and forth with centrifugal force and undergo various deformations, which will undoubtedly accelerate the aging of the valve.
The life of this kind of rubber valve is generally three to five years, which is about the same as the life of a tire. Therefore, when replacing the tire, remember to replace it with the valve.
In response to the aging of rubber valves, metal valves are gradually being introduced on the market to appear in the eyes of consumers. Due to changes in materials, the price of metal valves will be much more expensive than rubber valves.
But the life span is two or three times that of the rubber valve. Mainly because the metal material is not so easy to oxidize, and the metal valve has better air tightness.
After purchasing the valve, in order to be able to correctly identify the quality of the product, we can first make a pot of water and put the valve in the water. If at this time, the valve is bubbling, it means this valve The mouth quality is not enough.
On the contrary, if there is no bubbling, it means that the valve meets the qualified standard. When a valve leak is found, it should be repaired or replaced with new parts in time, and it should not be forced to prevent the valve core from being twisted.
Before inflating the tire, it is best to clean the surrounding dust with an air gun to prevent dust from entering the inner tube.
At the same time, the valve cap is also very important. Its function is to isolate the air, prevent dust, water, oil, etc. from damaging the valve core sealing rubber, and extend the life of the valve core.
It is best to regularly check whether the valve and valve cap are normal, maintain the air seal of the tire, prolong the service life of the tire and maintain the correct tire pressure.
