Abstract
A method for predicting, regulating and controlling a wear characteristic of a flow channel in a valve. The method comprises: pasting an aluminum sheet in a valve core, and testing a wear rate; regulating inlet pressure, and obtaining distribution characteristics of a pressure field and a velocity field; establishing an association relationship between the wear rate and pressure and a flow velocity; increasing the inlet pressure, and drawing a discrete data curve and a continuous curve; obtaining a discrete data change curve and a continuous curve of the wear rate along with an opening degree of the valve core; obtaining an association relationship graph between the wear rate of the aluminum sheet and the inlet pressure and the opening degree of the valve core; and performing comparison and determination on a real-time wear rate actual value of the aluminum sheet and a critical wear rate value.
