摘　　要：对大流量插装式液控单向阀制造样机进行了阀口密封性、开启特性和静态特性试验测试。应用仿真技术对插装式液控单向阀阀口在不同阀套锥角时的流场特性进行了计算分析,并将样机模型的计算结果与试验测试结果作了对比分析。得出:不同的阀套锥角对插装式液控单向阀的阀口流场特性影响显著,合理选取阀套锥角,可使阀口处的压力损失减小,阀口气穴现象和噪声的生成机率减低,阀的刚度增大,阀口流动状态稳定,阀的性能得到提升。为大流量插装式液控单向阀的阀口结构设计提供了理论支持。This article conducted experimental tests on the sealing performance,opening characteristics,and static characteristics of a prototype of a large flow plug-in hydraulic control one-way valve.By applying simulation technology,the flow field characteristics of the plug-in hydraulic control one-way valve port at different valve sleeve cone angles were calculated and analyzed,and the calculation results of the prototype model were compared and analyzed with the experimental test results.It is concluded that different valve sleeve cone angles have a significant impact on the flow field characteristics of the valve port of the plug-in hydraulic control one-way valve.Reasonable selection of valve sleeve cone angles can reduce pressure loss at the valve port,reduce the probability of valve port cavitation and noise generation,increase the stiffness of the valve,stabilize the flow state at the valve port,and improve the performance of the valve.This provides theoretical support for the design of the valve port structure of large flow plug-in hydraulic control one-way valves.
