Problems solved by technology
In order to prevent high-pressure air from escaping from the oil suction pipe when the compressor is shut down, it is usually necessary to equip a control valve such as a solenoid valve, but for those small air compression devices, it will undoubtedly increase the complexity of control and increase the production cost

The invention relates to a gas-oil separation device for a compressor. The gas-oil separation device comprises a housing 1, a seal 2, a filter element 4 and an oil cup 5, wherein a separation umbrella3 is arranged under the oil cup 5, an air inlet 13 is correspondingly arranged under the separation umbrella 3, the upper part of the separation umbrella 3 is provided with a guide rod 6, and a valverod 11 is arranged on the lower part of the separation umbrella 3. An oil return hole 8 is arranged under the oil cup 5 and is controlled to be opened or closed by an oil return valve comprising theguide rod 6, a sealing ring 7 and the oil return hole 8. When the compressor is started, the oil return valve is closed; when the compressor is powered off, the oil return valve is opened; an oil discharge hole 12 is arranged on the seal 2 and is controlled to be opened or closed by a control valve comprising the valve rod 11 and the oil discharge hole 12; when the compressor is started, the control valve is opened; and when the compressor is powered off, the control valve is closed. As compressed air is fully utilized as the driving force for the oil return valve and the control valve, special operation and control do not need, and therefore the gas-oil separation device has the advantages of convenient operation and control and low production cost.
Description
technical field [0001] The invention relates to an oil-gas separation device, in particular to a compressor oil-gas separation device, more specifically to an air compressor oil-gas separation device. Background technique [0002] Air compressors are widely used mechanical and electrical products. For the needs of lubrication, sealing and cooling, liquid oil is often used. These oils lubricate the moving pairs, thus reducing friction and wear; at the same time, due to the presence of lubricating oil, the amount of leakage through the fit clearance is greatly reduced; finally, the lubricating oil can cool the key moving parts of the compressor such as bearings , rotor and cylinder, etc., thereby improving the reliability of the compressor. [0003] The problem is that under the influence of the high temperature generated by the compressor, the lubricating oil is often mixed with the high-pressure air in the form of mist and discharged from the exhaust port of the compressor ...
