Simulation Analysis of Influence of Rotary Valve Spool Gap on Leakage
Based on the theory of orifice flow and parallel plate slit flow,the geometric size of polygonal port area distributed on the surface was obtained by Boolean operation.The area was meshed and the fluid dynamics analysis theory was used to explore the simulation calculation method of the leakage amount at the complex shape valve port distributed on the surface,which provided a simulation basis for guiding the design and calculation of this kind of rotary valve.At the same time,the leakage of different gap sizes under given pressure is calculated theoretically,which provides a reference for the selection of matching gap.At the same time,the leakage amount under different liquid viscosity and different inlet pressure is also calculated.At last,some experiences in design,manufacture and test of this kind of rotary valve are summarized briefly.
