The valve nozzle body (base) is the only way for the gas to enter the tire, while accommodating and protecting the valve core;Fastening nut is known from the name of its role is to make the valve mouth and the wheel ring fixed more firmly;Two gaskets of different materials cooperate with the fastening of the fastening nut;The rubber sealing gasket plays the role of sealing to prevent air leakage on the inside of the wheel ring;The often lost valve cap can avoid the intrusion of foreign bodies on the valve, and achieve the second sealing of the valve.While ensuring the smooth injection of gas into the tire, the valve core also has the function of preventing gas leakage.

Valve nozzle mounting

The valve nozzle assembly can be divided into screw-mount type, compression type and buckle type.For example, the assembly of the rubber valve mouth is the buckle type. The valve base is provided with a slot to fix it with the wheel ring, which also leads to the disposable use of the valve.
