本文研究一种新型农业用调压阀结构,调压原理为弹簧调压。通过弹簧调压试验,得出弹簧为同一型号时,改变系统的入口压力,其出口压力降低并基本保持不变;入口压力一定时,弹簧的直径型号越小,出口压力越低,即弹簧调压作用越明显。 This paper studies a new agricultural pressure regulating valve structure, the principle of pressure regulating spring pressure. Through the spring pressure test, it is concluded that when the spring is of the same type, the inlet pressure of the system is changed, and the outlet pressure of the system is reduced and remains substantially unchanged. When the inlet pressure is constant, the smaller the diameter of the spring, the lower the outlet pressure, The more obvious pressure effect.
