The two functions of the minimum pressure valve of the air compressor

1. The function of the minimum pressure valve is to buffer it. When the machine is loaded, we assume that it is discharged into the atmosphere, and the large pressure difference generated in the machine before and after separation will all be added to the separator, causing damage to the separator core. harm;

2. The oil lubrication of the machine is carried out by the pressure difference of the machine itself. There is no additional oil pump to assist. When the machine is in the no-load state, a certain pressure is still required to maintain the oil circulation, so the intake valve is relatively closed, and the minimum pressure valve prevents pressure leakage. , so as to ensure the lubricating oil circulation.
