Beschreibung
Zusammenfassung:The utility model relates to the technical field of hydrogen supply, and discloses a hydrogen flow control valve group, which comprises a first ejector, a second ejector, an ejection fluid inlet control unit and a hydrogen inlet control unit, the ejection fluid inlet control unit comprises a first two-position three-way electromagnetic valve, and the hydrogen inlet control unit comprises a second two-position three-way electromagnetic valve. The hydrogen inlet control unit comprises a second two-position three-way electromagnetic valve and a plurality of hydrogen ejectors, and the hydrogen inlet control unit communicates with the first ejector or the second ejector through the second two-position three-way electromagnetic valve and controls the hydrogen flow through the hydrogen ejectors. The two two-position three-way electromagnetic valves are used for respectively controlling hydrogen and driving fluid to enter the first ejector or the second ejector, the injection ports of the double ejectors are physical
