Pressure-regulating dual anti-burst tire safety valve

Abstract

The invention discloses a pressure-regulating dual anti-burst tire safety valve, relating to the improvement of a tire inflating valve. The safety valve is characterized in that the valve body is fixedly matched with a dust-proof cap in a thread mode; the dust-proof cap is provided with a vent hole; a core is installed in a ventilation channel in the valve body through a limit groove; a core cap with the limit groove is fixed on the upper part in the valve body through the threads; a core bar is fixed on the center line of the inner cavity of the core; the core bar penetrates through the core cap and is matched with the core cap in a sliding mode; a pressure limiting spring is arranged outside the core bar and in the limit groove of the core cap; and top end of the core cap is provided with transversely protruded cap outer edge. The safety valve has the beneficial effects of making up the anti-burst tire function which the existing inflating valve does not have and overcoming the defect that the inflating valve bursts under the action of pressure, thereby not only inflating tires, but also regulating and discharging pressure for the tires to ensure the normal working pressure of the tires, prolonging the service life of the tires, saving fuels, and preventing accidents due to tire burst and valve burst.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle parts and relates to an improvement of a tire valve. Background technique [0002] At present, the valve core valve on the tire of a motor vehicle can only inflate and seal the tire. When the vehicle is running at high speed, due to friction, the temperature of the tire will increase, and the air pressure in the tire will also increase. , when the tire pressure limit value is exceeded, tire blowouts often occur and cause traffic accidents, which bring great hidden dangers to safe driving. The existing valve core and the valve mouth cannot automatically regulate and release pressure for tires. The connecting part of the air valve of the tire of the existing car and the wheel rim is all rubber products, which is oxidized and aged in the air. Under the effect of pressure, the air valve itself will also burst, and serious consequences will occur. Contents of the invention [0003] The object...

Problems solved by technology

[0002] At present, the valve core valve on the tire of a motor vehicle can only inflate and seal the tire. When the vehicle is running at high speed, due to friction, the temperature of the tire will increase, and the air pressure in the tire will also increase. , when the tire pressure limit value is exceeded, tire blowouts often occur and cause traffic accidents, which bring great hidden dangers to safe driving

Existing valve cores and valves cannot automatically adjust and release pressure for tires

The connecting part of the tire valve and the rim of the existing car is made of rubber, which is oxidized and aged in the air. Under the action of pressure, the valve itself will burst, causing serious consequences.
