Abstract

A leak-proof valve for a run-flat tire comprises a first leak-proof valve and a second leak-proof valve; the first leak-proof valve comprises a first one-way valve and a first air shutoff valve; the second leak-proof valve comprises a second one-way valve and a second air shutoff valve; when an outer tire is inflated, a first inner tire is inflated by the first leak-proof valve and a second inner tire is inflated by the second leak-proof valve; the first leak-proof valve is provided with a first driving rod and the second leak-proof valve is provided with a second driving rod; when the outer tire loses pressure, the first leak-proof valve is shut off by using the first one-way valve and the first air shutoff valve, the first inner tire is kept in a pressurized state and the first inner tire supports the outer tire through a first external supporting column and a first internal supporting column; and when the outer tire and the first inner tire lose pressures, the second leak-proof valve is shut off by using the second one-way valve and the second air shutoff valve, the second inner tire is kept in a pressurized state and the second inner tire supports the outer tire through the first external supporting column, the first internal supporting column, a second external supporting column and a second internal supporting column; therefore, tire leaning accidents are reduced.

Description

technical field [0001] The invention relates to an anti-leakage valve of an anti-explosion tire of a motor vehicle. Background technique [0002] When a motor vehicle is running on the expressway, once the tire of the motor vehicle is blown out, the motor vehicle is prone to a partial tire failure, which makes the motor vehicle run out of control and causes traffic accidents; accident needs. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a leak-proof valve for run-flat tires, which is used to prevent or reduce the occurrence of traffic accidents. [0004] The technical scheme adopted in the present invention is: the explosion-proof tire includes a wheel rim, an outer tire, an inner tube and an anti-leakage valve, the anti-leakage valve includes a first anti-leakage valve and a second anti-leakage valve, the outer tire is connected with the rim, and the inner tube is located at the outer ...
