Núcleo de válvula de neumático

Tire valve core is also called tire air tight core. Mainly used for tire air intake and prevent tire air leakage. The main body of the tire valve core is a small upper hollow, solid column at the lower end, and a small hole is opened on the side of the lower end and connected with the hollow part. Tire valve core is mainly divided into: British valve pin, American valve core, French valve core, in addition to the German valve pin and Italian valve core.

Tire valve core in fact, it is a one-way valve, when you pump the bicycle tire, the compressed air in the air cylinder from the hollow part into the valve core, the elastic rubber tube "top" up, the air into the tire; When not pumped, the elastic rubber hose tightens to cover holes in the side, preventing air from flowing back through the tire.

El núcleo de la válvula del neumático con anillo de goma especial, alta resistencia a la presión, el núcleo de la válvula resistente a la corrosión está hecho básicamente de material de cobre, pero debido a que la proporción del material de cobre es significativa, afectará el equilibrio del neumático y el costo del material de cobre es Protección alta y no muy ambiental, por lo que ahora algunos núcleos de válvulas están hechos de aleación de aluminio.
