Abstract
Flow control valve is the basic component of the hydraulic system, and its performance plays a vital role in the working characteristics of the hydraulic system. In this paper, based on the unique structure of a micro-flow regulating valve, in order to prevent the structure between the valve core and the valve sleeve from deforming under the action of throttling temperature rise and flow pressure, the interaction between the valve core and the valve body at the throttling notch will cause flow fluctuation. Establish a three-dimensional model and a flow field model of the micro-control valve. Based on CFD, fluid-heat-solid coupling simulation is used to analyze the deformation of the valve core sleeve caused by flow rate, pressure and throttling temperature rise. The variation and distribution law of the flow field is obtained when the spool works at different angles and pressure differences. It provides a theoretical reference for the structural optimization design and improvement of this type of flow control valve.
