The function of the tire valve core is to act as a tire inflation interface and a deflation valve, and to keep the inflated air from leaking out; it is also a device for checking the tire pressure. This component is very small, but it is related to the safety of the car. So in what ways does the valve ensure the air tightness of the tire?
The triple air tightness of the valve core is guaranteed. It is one of the core components in the valve. Through the valve core, we can easily inflate and deflate the tire. The double air tightness of the valve cap is guaranteed. The door caps are divided into plastic caps and metal caps. They are screwed and sealed by the metal nozzle rod. At the same time, the metal nozzle rod of the valve nozzle and the sealing gasket at the bottom of the valve cap can be closely attached to achieve the dual functions of dust and air tightness.
The tire valve core base is sealed with the rim hole. There are two situations. The rubber valve base is pulled in through a snap-in type to ensure that the rubber base fits closely with the rim hole. The metal valve base is tightened with the nut to make the metal valve base closely fit the rim hole to ensure the air tightness of the tire. In the process of valve production, the material and processing accuracy of the product will directly affect the air tightness of the valve. Strengthening the strict 100% air tightness test of the valve product is the most indispensable step.
