摘要： A hydrogen supply combination valve having flow regulation and pressure stabilization functions includes a first-stage pressure reduction valve, a second-stage pressure reduction and flow regulation valve, and a second-stage pressure reduction and regulation valve. The first-stage pressure reduction valve realizes main throttling and pressure reduction effects, and performs first-stage pressure reduction on high-pressure hydrogen. The second-stage pressure reduction and flow regulation valve can further perform second-stage pressure reduction on the hydrogen after first-stage pressure reduction, and can realize flow regulation. The second-stage pressure reduction and regulation valve can further perform second-stage pressure reduction on the hydrogen after first-stage pressure reduction.
