摘要/Abstract

摘要： 插装阀在工作过程中会形成偏心锥形缝隙流场，针对阀芯在此流场容易受到较大卡紧力，从而影响动态响应速度问题，提出一种新型插装阀芯结构。采用数值模拟方法分析了间隙流场在速度分布、压力分布、阀芯运动速度和泄漏量等方面的流动特性。流体动力学(CFD)计算结果表明，在插装阀芯表面设置导流槽，增加了阀芯的连接长度，使径向压力分布和速度分布更均匀，有效地减小了侧向力，同时保证了泄漏不会太大。此研究为优化插装阀以减少卡滞和提高响应频率提供了理论指导和依据。

Abstract: he valve core is readily subjected to a large lateral force which affects the dynamic response speed. Here, a new type of cartridge valve core structure is proposed to solve this problem. The numerical simulation method is applied to analyze the flow characteristics of clearance flow field on velocity distribution, pressure distribution, valve core motion speed, and leakage. The results using computational fluid dynamics (CFD) show that the guide groove is set on the surface of the cartridge valve core, increasing the connecting length of the valve core, forming a uniform radial pressure distribution and velocity distribution, effectively reducing the lateral force, and at the same time ensuring that the leak is not too big. These findings provide theoretical guidance and a basis for optimizing cartridge valve to reduce the occurrence of jamming and improve the response frequency.

Key words: cartridge valve, guide groove, lateral force, finite element simulation
