Description

TECHNICAL FIELD

[0001] The utility model relates to valve nozzle technical field especially relates to a sealed valve nozzle. BACKGROUND

[0002] Valve nozzle is used to inflate the tire. It is widely used in bicycles, tricycles, trolleys and some light motorcycles. At present, the existing valve nozzle in China is all equipped with a rubber tube (valve core) on the valve needle. It is easy to stick together in high temperature in summer and easy to freeze shrink in low temperature in winter. It adopts thread compression sealing, and the rubber tube is easy to be broken at the sealing place, causing air leakage phenomenon, so the valve core needs to be replaced frequently. In addition, there is also a valve needle without rubber tube. It has a ring of rubber at the sealing place of the valve needle, which is also easy to break and leak air. There is also a rubber plug in the valve needle that can move up and down. The rubber plug is easy to stick in the valve needle, causing the air to be difficult to pump in, and it is also difficult to process.

[0003] When in use, in the prior art, if the vehicle shakes during driving, the ball is easy to loosen and shake, and the gas in the inner tube is easy to leak after the ball moves, so the staff needs to pump regularly, which reduces the work efficiency.
