Abstract

The present application relates to the technical field of aerospace, in particular to a rectangular cross-section adjustable cavitation venturi with large-scale flow regulation. A rectangular cross-section adjustable cavitation venturi with large-scale flow adjustment, comprising a driving member, a sliding block and a base; a first groove is formed on the base; an output shaft of the driving member is connected with the sliding block, and can drive the sliding block The first slot moves along the first direction; a rectangular flow channel is formed between the bottom wall of the slider and the bottom wall of the first slot; when the driving member drives the slider to move along the first slot in the first slot When moving in the direction, the cross-sectional area of ​​the rectangular flow channel can be changed to regulate the flow of liquid or gas. The present application uses the driving member to directly change the cross-sectional area of ​​the rectangular flow channel, which can realize a wide range of flow adjustment.

Description

technical field [0001] The present application relates to the technical field of aerospace, in particular to a rectangular cross-section adjustable cavitation venturi with large-scale flow adjustment. Background technique [0002] The existing adjustable cavitation venturi usually has a circular cross-section. The minimum flow cross-sectional area at the throat is adjusted through the cooperation of the movable spool with the constricted section, the throat and the expansion section, so as to achieve the purpose of regulating the flow. . [0003] When the adjustable cavitation venturi is used to adjust the flow rate, it is usually difficult to achieve a large-scale flow adjustment because the area of ​​the annular slit cross-section formed by the cooperation of the circular constricted section and the circular valve core does not change much. [0004] Therefore, there is an urgent need for a rectangular cross-section adjustable cavitation venturi with large-scale flow regul...
