The function of the Tire Valves is to serve 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 tire pressure. This part is very small, but it is related to the driving safety of the car. So how does the valve ensure the air tightness of the tire? Below we describe them one by one.
1. Triple air tightness guarantee for valve core
The valve core is one of the core components in the valve. Through the valve core, we can easily inflate and deflate the tire.
2. Double air tightness guarantee of valve cap
The valve cap is divided into plastic cap and metal cap. It is sealed by screw teeth and metal nozzle rod. At the same time, the valve metal nozzle rod and the sealing gasket at the bottom of the valve cap can be closely fitted in the tightened state, realizing the dual functions of dustproof and airtight. .
3. The valve base and the rim hole are sealed
There are two cases, the rubber valve base is pulled in through a snap-type, so as to ensure the close fit between the rubber base and the rim hole.
The metal valve base is made by tightening the nut to make the metal valve base fit closely with the rim hole, so as to ensure the air tightness of the tire.
The structure of the valve product itself guarantees multiple air tightness. Of course, in the process of producing the valve, the material and processing accuracy of the product will directly affect the air tightness of the valve. Confidentiality detection is an indispensable step.
