Optimization Design and Manufacture of 3D Printing Labyrinth Regulating Valve Disc
In view of cavitation and erosion in control valves under high pressure drop conditions,a novel labyrinth disc was proposed based on traditional labyrinth control valve,combined with metal 3D printing technology and valve design,and computational fluid dynamics(CFD)software was utilized to perform flow field simulation analysis.316L stainless steel specimens were produced by selective laser melting(SLM),and compared with rolled specimens in terms of mechanical properties.The results indicate that the novel labyrinth disc possesses desirable flow performance,which can effectively reduce the pressure fluctuation and outlet velocity of the medium in the flow channel while meet-ing the actual working condition requirements,and reduce the risk of cavitation and erosion.The mechanical properties of 3D printed specimens are superior to those of rolled specimens,meeting operating requirements of valve parts.
