Stress Analysis and Exploration of the Rotary Valve

Abstract

the low pressure oil chamber and the high pressure oil chamber act directly on Both sides of the rotary valve. It will be large axial force to the valve body If the system working pressure is greater. The resulting outcome is low vibration frequency of the rotary valve driven hydraulic exciter. How to improve the hydraulic exciter frequency?We can improve the speed of the rotary valve or increase the number of rotary valve guide groove. But if we increase the tank guided number ,the diameter of the rotary valve spoo must be increased. Design a rotary valve without axial force can solve the problem of the rotary valve spool shaft size restricted. By calculation and analysis of the rotary valve spool suffered axial force . The work of a single rotary valve chamber pressure problems can be solved spool axial force
