| description | The invention provides a two-stage swirler. The two-stage swirler comprises a first-stage swirler body, a second-stage swirler body and a baffle ring. A convex lug is fixed at the mounting end of the primary swirler, the baffle ring is fixed on the secondary swirler, a concave cavity is formed in the baffle ring, the mounting end of the primary swirler and the convex lug are arranged in the baffle ring and can move in the baffle ring along the radial direction of the baffle ring, the convex lug is arranged in the concave cavity in a penetrating manner, and the concave cavity extends towards the outer side direction of the baffle ring so as to form an extended groove wall matched with the peripheral side wall surface of the convex lug. In order to prevent the situation that in the actual use process, due to the influences of engine vibration, fuel nozzle limiting and airflow impact, a convex lug of a first-stage swirler and a concave cavity of a baffle ring are repeatedly collided and abraded, the convex lug i |
