摘　　要：在交通车辆和特种工程车辆中,经常采用液压系统进行传动和动作控制,而液压调压阀广泛地应用在液压系统中,当系统中某一个支路的工作压力与系统压力不同时,通过液压调压阀能够降低系统压力,从而保证该支路的工作压力稳定,并且避免对液压系统压力产生影响。然而,当调压过程中降低的压力差值较大时,经过阀口的压降变大,因此,液压阀此处的流体流动较为紊乱,容易产生流体噪声及压力波动。文中提出了一种新型的双边控制式的调压阀,详细分析了该新型调压阀的工作原理,通过在调压阀的阀芯结构上设计两个控制边,从而减小了通过每个控制边的压降,保证了调压阀工作稳定性,详细分析了传统调压阀的结构特点,设计了新型调压阀的基本结构,搭建了AMESim仿真分析模型,并通过仿真分析模型验证了新型的双边控制液压阀的工作原理的正确性。In terms of transportation vehicles and special engineering vehicles,hydraulic systems are often used for transmission and action control,and hydraulic regulators are widely used in hydraulic systems.When the hydraulic system branch’s pressure is different from the hydraulic system’s pressure,the hydraulic regulator is used to reduce the hydraulic system’s pressure.As a result,the hydraulic system branch is working with stabilized pressure,and any impact on the hydraulic system’s pressure can be avoided.However,in the process of pressure regulation,when the pressure difference reduces significantly,the pressure drop through the valve port is large,so the fluid is flowing turbulently at the hydraulic valve,which is likely to produce fluid noise and pressure fluctuation.In this article,efforts are made to design a new bilateral-control regulator and expound its working principle;two control sides are designed on the regulator’s spool structure,which reduces the pressure drop through each control side and ensures that the regulator is operating smoothly.Besides,the in-depth analysis is conducted on the traditional regulator’s structural characteristics,and the new regulator’s basic structure is designed.Finally,the model of AMESim simulation and analysis is set up;on this basis,it is verified that the new bilateral-control regulator’s working principle is correct.
