- Abstract:
- The simulation research of impact characteristics of valve spool and valve seat in selector valve was carried out to eliminate the bind-seize phenomenon caused by impact deformation of valve spool and valve seat, which emerged in the development process of a selector valve. The process of impact between valve seat and spool, and the influence of different height on impact characteristics were analyzed quantitatively. The revised design for the selector valve was performed according to the simulation result. The test result shows that the improved selector valve can meet the operating requirement.
