How to clean the screw air compressor minimum pressure valve


The composition of the minimum pressure valve: the minimum pressure valve is composed of a valve body, a valve core, an adjusting nut, a spring, a sealing element and the like.


The role of the minimum pressure valve: the minimum pressure valve mainly establishes the internal pressure of the unit, promotes the circulation of the lubricating oil, and satisfies the working pressure of the unloading valve. In addition, the minimum pressure valve also functions as a check valve to prevent the unit from storing gas during the unloading operation. The compressed air in the tank flows back to the air compressor.


Disassembly of the minimum pressure valve: The structure of the minimum pressure valve is very simple. Unscrew the nut of the screw air compressor between the valve core and the valve body. The smallest pressure valve spool of the small unit is built into the valve body. Remove all internal components by removing the valve body cover.


Cleaning the minimum pressure valve: The cleaning agent should be soapy water, diesel oil, clean gasoline, Tianna water, etc. The cleaning agent should be selected according to the degree of dirt. It is generally recommended to use soapy water or diesel oil for cleaning. If the dirt of the minimum pressure valve is serious, replace it with a new one when cleaning.


Assembly of the minimum pressure valve: assembly components according to the reverse steps of disassembly. Since the structure of the minimum pressure valve is very simple, the assembly process is not described one by one, but it should be noted that if there is a U-ring inside, pay attention to the U-ring. direction.
