Background
At present, liquid or oil filling is assembled by a pump, a flowmeter, a sensor, a computer board and other complex devices, and has the advantages of high cost, large volume and no portability and mobile use.
Therefore, when the self-sealing oil gun is used for filling oil, the switch handle is lifted, the ejector rod opens the main valve, and pressure oil flows into the lower cavity of the main valve through the main valve. Under the action of pressure oil, the inclined valve is opened, so that the oil flows into the oil receiving container through the oil gun nozzle. During the oil flow, air in the cavity behind the inclined valve seat is entrained. When the oil receiving container is not filled with oil, the carried air is compensated by the air pipe and the air pipe mouth. When the oil receiving container is filled with oil, the air hole is blocked by the oil, air cannot be compensated, negative pressure is formed after the air in the cavity is taken away, at the moment, the diaphragm deforms upwards, and the diaphragm shaft moves upwards along with the diaphragm. The steel ball with the stopping function slides to the center, the shaft falls down, the function of a fixed fulcrum is lost, and the main valve is automatically closed under the action of the spring to realize the self-sealing function.
However, the self-sealing oil gun can be automatically closed to perform the self-sealing function only when the oil receiving container is full of oil, so that inconvenience is brought to operators, the operators generally need to visually observe, and then when the oil receiving container reaches a preset point, the flow is reduced and controlled gradually. Meanwhile, the self-sealing oil gun cannot achieve the self-sealing effect of quantitative oil filling.
