Leakage-proof butterfly valve for new energy fuel cell vehicle

Abstract

The invention provides an anti-leakage butterfly valve for a new energy fuel cell automobile, which is applied to the technical field of new energy automobile parts, a motor (1) and a rotating shaft (9) are mounted in a shell (6) of the anti-leakage butterfly valve for the new energy fuel cell automobile, the rotating shaft (9) is positioned in a gas channel (18) of the shell (6), a sealing seat (11) is arranged in the gas channel (18), a sealing framework (8) is arranged on the rotating shaft (9), and the sealing framework (8) is arranged on the rotating shaft (9). According to the leak-proof butterfly valve for the new energy fuel cell automobile, the gas flow can be accurately adjusted, it is ensured that a fuel cell works under the optimal working condition all the time, energy consumption is reduced, gas flow can be completely cut off after power failure, good sealing is achieved, the service life of the fuel cell is prolonged, and the leak-proof butterfly valve is suitable for the new energy fuel cell automobile. And the ice breaking capacity is achieved, the ice breaking device adapts to the severe environment, and the performance is improved.

Description

technical field [0001] The invention belongs to the technical field of new energy automobile parts, and more specifically relates to an anti-leakage butterfly valve for a new energy fuel cell automobile. Background technique [0002] With the increasingly serious problems of energy shortage and environmental pollution, the automotive industry is developing towards low-emission and high-efficiency battery-driven or non-fossil energy-driven new energy sources. This type of new energy vehicle technology has extremely high requirements on gas flow control and sealing performance. At present, the sealing performance, durability and position accuracy of throttle valves in the market are generally not very high, which cannot guarantee the driving safety of new energy vehicles and meet the requirements of low energy consumption. In the prior art, non-eccentric butterfly valves or single-eccentric butterfly valves are commonly used. The axis line of the valve plate and the rotating...

Problems solved by technology

However, the rotation angle required for the valve plate to separate from the housing is large, and the rubber sealing ring will rub against the metal housing for a long time, causing the rubber sealing ring to be scraped and squeezed unnecessarily, causing the rubber sealing ring to be worn and broken. crumbs, which cannot meet airtightness and will contaminate the reactor
