摘 要:A new type of pressure regulating valve for agriculture irrigation, which used spring to regulate pressure was studied. Through the spring regulating pres-sure test, it concluded that for the pressure regulating valve with same spring mod-el, the outer pressure became smal er than the inlet pressure of the system and with the changes of inlet pressure, the outlet pressure remained almost the same, and that when inlet pressure was constant, the valve with smal er spring diameter had lower outlet pressure, indicating that the pressure regulating effect of the spring was more obvious with smal er diameter.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。
关 键 词:Pressure regulating valve SPRING Pressure regulating effect
