Novel adjustable ejector

The invention discloses a novel adjustable ejector, which relates to the technical field of ejectors, and comprises a rotating rod, an actuating mechanism connecting part, an adjusting rod, a nozzle, a primary flow inlet, a secondary flow inlet, a packing gland, a packing body, a packing gasket, a blocky structure and an O-shaped ring, a rotating rod is arranged at the other end of the executing mechanism, a packing gasket is arranged in one end of the executing mechanism, a packing body is arranged on one side of the packing gasket, and a packing gland is arranged at the other end of the packing body. In the process of adjusting the flow of the ejector, surface sealing between a block-shaped structure and a fluid channel replaces linear sealing between an adjusting device and a throat part or a throat part wall surface in an original structure, and an O-shaped ring is additionally arranged on a sealing surface, so that the sealing contact area is larger, and the sealing is firmer. 本发明公开了一种新型可调喷射器，涉及喷射器的技术领域，
