摘　　要：针对高压差下调节阀阀芯窗口出现的空化现象,探讨了基于限流孔板理论的优化设计方法的可行性。空化是流体在特定条件下产生气泡及其突然崩溃的过程,对工业安全生产和流量稳定性产生不利影响。研究中,利用限流孔板控制流量的装置,对复合式调节阀进行了优化设计。结果显示,优化后的调节阀在特定的高压差工况下,能有效减少气含率,从而抑制空化,确保流体流量恢复与增强工作稳定性。此项研究为阀类产品提供了新的设计思路,验证了基于限流孔板理论的优化方法对于抑制调节阀空化的显著效果,具有重要的工程应用价值。The feasibility of the optimization design method based on the restrictive orifice plate theory is explored for the cavitation phenomenon occurring in the spool window of the regulating valve under high differential pressure.Cavitation is a process in which a fluid produces bubbles and their sudden collapse under specific conditions,which adversely affects industrial safety production and flow stability.In the study,the optimized design of a composite control valve was carried out by using the device of flow-limiting orifice plate to control the flow.The results show that the optimized regulating valve can effectively reduce the gas content rate under specific high-pressure differential operating conditions,thus suppressing cavitation and ensuring fluid flow recovery with enhanced work stability.This study provides new design ideas for valve products,and verifies that the optimization method based on the theory of restriction orifice plate has a significant effect on suppressing the cavitation of the regulating valve,which has important engineering application value.
