Description

Degassing filter

Technical Field

The utility model relates to the technical field of filtering devices, in particular to a degassing filter.

Background

The degassing filter is one of the accessory devices of the flowmeter, and has the advantages of separating gas in a pipeline flowing medium and filtering impurities in the medium, thereby ensuring the metering precision of the flowmeter, prolonging the service life of the flowmeter and the like, removing solid impurities through a filter screen arranged in a cylinder after finished oil flows in from an inlet, changing the flowing direction of liquid when the liquid passes through a filter screen assembly, fully running out free gas and partial dissolved gas in the oil, and rising the gas to the top of a separator to form a gas space and generate an oil-gas interface. The pressure of the gas is increased, the volume is increased, the oil-gas interface is lowered, the floating ball device is lowered to a certain extent to act, the air valve is opened to remove the gas, the oil-gas interface is raised, the air space is reduced, the floating ball device is closed, and thus the purpose of separating oil, gas and solid is achieved through the medium flowing through the degassing filter.

Although the finished oil flowing through the degassing filter is mixed with solid impurities, the finished oil can be separated below the filter screen by the filter screen in a blocking way and is deposited on the bottom surface of the inner cavity of the degassing filter, the traditional finished oil flowing through the degassing filter needs to be disassembled, so that the solid impurities on the bottom surface of the inner cavity of the degassing filter can be completely cleaned, and the solid impurities cannot be directly discharged. In view of this, we propose a degassing filter.
