压力直接电检测型比例减压阀权龙，林廷圻，史维祥近来液压控制系统的一个发展趋势是用一个油源结合大容量蓄能器代替多个小油源进行集中供油。为满足多个负载对不同工作压力的要求，必须用减压阀来获得与所连接负载流量无关的支路压力。但是传统的比例减压阀因不能抑制导... Pressure Direct Detection Proportional Pressure Reducing Valve A recent trend in hydraulics control systems is the use of an oil source combined with a bulk accumulator to replace multiple small oil sources for centralized fuel supply. In order to meet the requirements of multiple loads for different working pressures, the relief valve must be used to obtain the branch pressure independent of the connected load flow. However, the traditional proportional pressure relief valve can not suppress the guide ...
