Study on Wear Properties of the Graphite-Sealing Surfaces in a Triple Eccentric Butterfly Valve Based on EDEM-Fluent Coupling

When using valves and pipes, erosion wear is a major issue. Erosion can result in equipment shutdown, material replacement, other issues, as well the failure of sealing surfaces. The depth primarily determined by particle velocity, size, target material, use conditions. A combination discrete element method (DEM) computational fluid dynamics (CFD) was used this study. dynamic process collision with surface also considered. then calculated Archard’s abrasive theory. graphite-sealing gas-solid two-phase flow medium numerically simulated high-temperature triple eccentric butterfly valve above theory method. patterns surfaces were investigated under various velocities, sizes, materials, service findings indicate that velocity size are positively related to rate. Soft greater than hard depth. decreases ambient temperature rises. As result, graphite has excellent resistance at high temperatures. feeding, however, must be wears characteristics three paper optimize prevention.
