The invention discloses a light-weight proportional valve with good sealing performance for a fuel cell. The light-weight proportional valve comprises a valve body, wherein the valve body is formed byconnecting a plurality of subsections with screw holes through bolts and threads, a main air inlet channel is formed in the valve body, a valve plate is arranged in the main air inlet channel, a center rod is arranged on the valve plate and arranged in the valve body, a motor sensor assembly is arranged at the top end of the center rod, the lower portion of the main air inlet channel perpendicularly communicates with a main air outlet channel through a valve seat arranged at the bottom of the valve body, an auxiliary air outlet channel communicates above the main air inlet channel in parallel, the valve plate is coated with a rubber layer through a vulcanization process, embedded parts used for bearing acting force of the bolts are embedded in the peripheries of screw holes formed in allthe parts of the valve body, the valve body is a plastic valve body, and the embedded parts and the plastic valve body are formed through one-time injection molding. According to the light-weight proportional valve, the embedded parts are embedded in the plastic valve body, so that the weight is light, and the strength is high; and the rubber layer is wrapped outside the valve plate, so that the sealing performance is good.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a fuel cell proportional valve with good sealing performance and light weight. Background technique [0002] Fuel vehicles use fuel cells as the power source. Except for the different power sources, fuel vehicles and pure electric vehicles have identical components such as drives and transmission systems. A pure fuel cell vehicle has only one power source, the fuel cell, and all the power of the vehicle is borne by the fuel cell. [0003] At present, most fuel vehicles use hybrid drive. On the basis of the fuel cell version, a set of batteries or supercapacitors are added as another power source. The main structures are: energy control unit, air compressor, fuel cell stack, high-pressure hydrogen storage bottle, power battery pack and electric motor; the high-pressure hydrogen storage bottle provides fuel, and the power battery pack provides additional power to allow the car to a...
