Valve structure

The valve body (base) is the only way for gas to enter the tire, while accommodating and protecting the valve core; the fastening nut is known by its name to make the valve and the rim more stable; The gasket of different materials is matched with the fastening nut; the rubber gasket acts as a seal on the inside of the rim to prevent air leakage; the valve cap that is often lost can avoid the foreign body from invading the valve. The secondary sealing of the valve is achieved; while the valve core ensures the gas is smoothly injected into the tire, it also has the function of preventing gas from leaking out.

Valve installation

The valve can be assembled into a screw-on type, a press-fit type and a snap-on type. For example, the assembly of the rubber valve is a snap type, and the valve base is provided with a card slot for fixing with the rim, which also causes a one-time use of the valve, and once removed, it cannot be reused. The metal valve is screw-fitted, and the valve is fixed by a gasket and a fastening nut, and can be reused after being removed.

In addition, in the process of installing the valve to the rim, there are some details worthy of attention. These details not only help the valve to be installed in place, but also help to ensure the airtightness of the valve and prolong its service life.
