摘要
针对高压降工况下调节阀易发生气蚀和冲蚀的问题,在传统迷宫式调节阀的基础上,结合金属3D打印技术和阀门设计,设计了一种新型迷宫盘片,并利用计算流体力学(CFD)软件进行了流场仿真分析.通过选择性激光熔化(SLM)制作了316L不锈钢新型迷宫盘片和试样,并与轧制试样进行了力学性能对比.结果表明,新型迷宫盘片具有良好的流通性能,在满足实际工况需求的同时,能有效降低流道内介质的压力波动和出口速度,减少气蚀和冲蚀的风险;3D打印试样的力学性能优于轧制试样,符合阀门零件的使用要求.
Abstract
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.
