过去采用的压气自动减荷系统由压力调节器和减荷阀组成,如图1所示。当储气罐内的压力达到额定值时,压力调节器阀芯被顶开,压气经压力调节器到减荷阀的柱塞腔内推动小柱塞,使蝶阀芯向上运动,关闭压缩机进气通道,使其停止进气而空转。当储气罐内的压力降低时,压力调节器内的调压弹簧作用使阀芯关闭,切断储气罐通向减荷
In the past, the automatic gas pressure relief system consists of a pressure regulator and a relief valve, as shown in Figure 1. When the pressure in the gas tank reaches the rated value, the pressure regulator spool is opened, and the gas pressure is pushed to the plunger cavity of the relief valve by the pressure regulator to push the small plunger so as to move the butterfly valve spool upward and close the compressor Gas channel, to stop the intake and idling. When the pressure inside the gas tank is reduced, the pressure regulator within the pressure regulating spring to close the spool, cut off the gas tank to the load shedding
