The minimum pressure valve of a screw air compressor is also called a pressure maintenance valve, also called a one-way valve. Its composition is composed of valve body, valve core, spring, sealing ring, adjusting screw, etc. The inlet end of the minimum pressure valve is generally connected to the outlet of the oil and gas cylinder, and the outlet end is generally connected to the inlet of the cooler.
The function of the minimum pressure valve:
1.It acts as a buffer. When the machine is loaded, assuming that it is discharged into the atmosphere, the large pressure difference between the inside of the machine before and after the separation will all be added to the separator, causing damage to the separator core;
2.The oil lubrication of the machine is carried out by the pressure difference of the machine itself, without additional oil pump assistance, when the machine is in 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 lubricating oil circulation.
3.The minimum pressure valve is mainly used to establish the internal pressure of the unit, promote the circulation of lubricating oil, meet the working pressure of the relief valve, etc., to ensure that there is a certain internal circulation pressure for lubricating oil to circulate after starting up and before loading, and maintain the oil separation tank When the pressure does not drop below 4Bar, the cycle pressure required by the lubricating oil shall be established first when starting to ensure the lubrication of the machine and provide power to a part of the mechanical loading valve to ensure that the loading valve can be opened. When the pressure exceeds 4Bar, it can reduce the flow rate of the air flowing through the oil-gas separator. In addition to ensuring the oil-gas separation effect, it can also protect the oil-gas separation filter element from damage due to excessive pressure difference.
4.The minimum pressure valve acts as a one-way valve to prevent the compressed air in the system from returning to the inside of the machine during shutdown.
