Pressure different blockage charge valve with plurality of air chambers and matched combined valve nozzle

Abstract

The invention discloses a pressure different blockage charge valve with a plurality of air chambers, which comprises a valve shell, a valve needle and a forked needle. The valve needle capable of freely sliding is arranged in the valve shell, and the inner end of the valve needle is provided with the forked needle. The valve needle is provided with an inner annular protrusion and an outer annular protrusion, and a sealing ring is sleeved between the inner annular protrusion and the outer annular protrusion. The invention also provided with a valve nozzle matched with the pressure different blockage charge valve with the plurality of air chambers. The valve nozzle comprises the pressure different blockage charge valve with the plurality of air chambers, and at least two inner valves; each inner valve comprises an inner valve shell and a valve core, the number and distribution of the forked needle and the valve core correspond, the charge valve and the inner valve are connected through pressing seal or tightly connected through internal thread, and the charge valve is sleeved with a compression nut. The pressure different blockage charge valve with the plurality of air chambers and the matched combined valve can achieve charge and exhaust of a tyre with a plurality of air chambers, balance the air pressure of the air chambers when the pressure different of each air chamber is small, and block and separate the communication of the air chambers when the pressure different of each air chamber is large.

Description

technical field [0001] The invention relates to the technical field of automobile wheel accessories, in particular to a multi-chamber pressure difference blocking inflatable valve and a valve nozzle formed by matching thereof, which are used to be installed on the rim of a multi-chamber self-balancing anti-leakage and explosion-proof safety wheel. Background technique [0002] The currently used tires, once gas leaks, will affect the normal driving of the vehicle, and the tires need to be replaced immediately, otherwise they will not be able to continue to run. If a tire blows out while driving at high speed, it will cause serious traffic accidents and endanger vehicles and personnel. safety. At present, dual-chamber tires are an effective way to solve this problem, but dual-chamber dual-chamber tires generally need to add exhaust to each tire separately, and the air pressure is unbalanced. If one side of the air chamber leaks or bursts , the double air chambers cannot be c...

Problems solved by technology

[0002] The currently used tires, once gas leaks, will affect the normal driving of the vehicle, and the tires need to be replaced immediately, otherwise they will not be able to continue to run. If a tire blows out while driving at high speed, it will cause serious traffic accidents and endanger vehicles and personnel. safety

At present, dual-chamber tires are an effective way to solve this problem, but dual-chamber dual-chamber tires generally need to exhaust each tire separately, and the air pressure is unbalanced. If one side of the air chamber leaks or bursts , the double air chambers cannot be cut off, and the normal driving of the car cannot be ensured
