Abstract
Abstract
The inclined flow channel, that is, the flow channel axis is not parallel to the slide valve axis, is used in this paper. This flow channel is more conducive to the flow of fluid, thus reducing the kinetic energy loss when the fluid passes through the slide valve. FLUENT simulation software is used to simulate and analyze the two-dimensional flow field of slide valve flow channel at different angles between flow channel axis and spool axis, and the flow field nephogram at different inclination angles are obtained. The result of simulation is analyzed and the optimal angle is 45 degrees. It also analyzes the influence of different inlet flow velocities on the flow field. The results show that the higher the velocity, the easier the formation of vortices and the greater influence on the pressure difference between inlet and outlet.
