一、引言传统的流体压力阀皆是按照弹簧力与压力相平衡的原理工作的,靠改变弹簧的压缩量来调节压力阀的出口或入口压力,并使其保持恒定。传统的流体压力阀的这种工作原理决定其具有如下特点:1.重复精度差在传统压力阀的结构
I. INTRODUCTION Traditional fluid pressure valves are based on the principle of spring force and pressure balance principle, by changing the amount of compression spring to adjust the pressure valve outlet or inlet pressure, and to keep it constant. The traditional working principle of the fluid pressure valve to determine its has the following characteristics: 1. Repeatability difference in the structure of the traditional pressure valve
