Title:
METHOD FOR USING ANTI-LEAKAGE VALVES FOR BLOWOUT PREVENTION TIRE
Document Type and Number:
WIPO Patent Application WO/2018/099446
Kind Code:
A1
Abstract:
A method for using anti-leakage valves (4) for a blowout prevention tire. The anti-leakage valves (4) for a blowout prevention tire comprise a first anti-leakage valve (5) and a second anti-leakage valve (6). The first anti-leakage valve (5) comprises a first one-way valve (9) and a first gas shutoff valve (10), and the second anti-leakage valve (6) comprises a second one-way valve (15) and a second gas shutoff valve (16). When the outer tire (2) is inflated, a first inner tire (7) is inflated by means of the first anti-leakage valve (5), and a second inner tire (8) is inflated by means of the second anti-leakage valve (6). The first anti-leakage valve (5) is provided with a first driving rod (20), and the second anti-leakage valve (6) is provided with a second driving rod (23). When the outer tire (2) loses a pressure, the first anti-leakage valve (5) is closed by means of the first one-way valve (9) and the first gas shutoff valve (10), the first inner tire (7) is kept in a pressurized state, and the first inner tire (7) supports the outer tire (2) by means of a first outer supporting column (27) and a first inner supporting column (28). When the outer tire (2) and the first inner tire (7) lose pressures, the second anti-leakage valve (6) is closed by means of the second one-way valve (15) and the second gas shutoff valve (16), the second inner tire (8) is kept in a pressurized state, and the second inner tire (8) supports the outer tire (2) by means of the first outer supporting column (27), the first inner supporting column (28), a second outer supporting column (29) and a second inner supporting column (30), so as to reduce occurrence of flat tire accidents.
