Pressure maintenance valve

The pressure maintenance valve is one of the important components of the air compressor. Keeping the pressure maintenance valve in the optimal state at all times can extend the service life of the air compressor.The pressure maintenance valve is located at the outlet of the oil fine separator above the oil and gas drum, and the pressure setting is openedAbout 0.45MPa. The function of the pressure maintenance valve is: A. Prioritize the establishment of cold during startupThe circulation pressure required by the fluid ensures lubrication of the body. B. When the pressure exceeds 0.45MPaAfter opening, it can reduce the air flow rate through the oil fine separator, ensuring the separation efficiency of the oil fine separatorIn addition, it can also protect the oil fine separator from damage due to excessive pressure difference.
