Mikovs Screw Air Compressor Accessories Brass Spring Check Valve Air Brass Stem Non Return Valve

The function of the oil return check valve: the oil-gas mixture compressed by the main engine is first separated from the oil-gas tank by centrifugal force. Because the oil is larger than the air, most of the oil in the oil-gas mixture falls to the oil tank by centrifugal force, and contains The compressed air with a small amount of oil is separated again by the oil-air separator. At this time, the lubricating oil separated by the oil-air separator will fall to the bottom of the oil-air separator. In order to prevent this part of oil from being taken away with the compressed air, the unit is designed with a The oil pipe pierces the bottom of the oil-gas separator, and through the effect of internal pressure, this part of oil is directly introduced to the lubricating bearing of the main engine, and there is a one-way valve on the oil pipe, called the oil return single-way valve, its function is to transfer the oil-gas separator The oil is smoothly recovered to the main engine without letting the oil of the main engine flow back to the oil-gas separator.
