Zusammenfassung:	The utility model discloses a flow regulation assembly and a core engine system, relates to the field of aero-engines, and aims to conveniently realize backpressure regulation of a core engine. The flow adjusting assembly comprises a first annular piece, a second annular piece and a butterfly valve. The first ring member is configured to be annular. The second annular piece is constructed to be annular; the second annular piece is arranged on the outer side of the first annular piece in a sleeving mode. The butterfly valve is arranged in a flow channel between the first annular piece and the second annular piece; the butterfly valve is configured to adjust a flow area of the flow passage. According to the flow adjusting assembly provided by the technical scheme, the butterfly valve is arranged in the flow channel between the first annular piece and the second annular piece, the flow area of the flow channel can be adjusted by adjusting the valve position of the butterfly valve, and then the air pressure of fl
