Detailed Description
Embodiments of a fuel gun oil leakage state monitoring platform, a method, and a storage medium according to the present invention will be described in detail below with reference to the accompanying drawings.
The appearance of the common oil gun mainly comprises an oil gun body, a hand guard, a limiting plate, a switch handle, a baffle plate, an automatic control rod and the like. A limiting plate is fixed on the hand guard of the oil gun, and three gears are arranged on the limiting plate. When the switch handle is opened, the baffle can incline 45-60 degrees. The opening of a switch of the oil gun is fixed on the limiting plate, and the oil outlet quantity of the oiling machine is controlled.
After the oil gun is started, the oil gun switch handle is opened, and oil passes through the main valve hole, the venturi tube, the outlet valve and the gun barrel and is output. When oil is added, oil rapidly flows through the venturi tube, a low-pressure area is formed in a sealing cavity between the venturi tube and the auxiliary valve seat, and one path of oil is led to the air nozzle at the front end of the gun barrel and reaches the upper cavity of the self-control membrane. When the oil or foam in the container does not reach the air tap, the low-pressure area is released due to the large ventilation capacity of the air tap; when the oil or foam submerges the air tap, the air tap is blocked, negative pressure is formed in the upper cavity of the self-control membrane, and the self-control membrane moves upwards and the steel balls slide down.
The self-sealing rod slides downwards under the pressure of the main valve, and simultaneously drives the switch to trip the support plate, so that the main valve is closed, and the oil gun is self-sealed. After the oil gun is self-sealed, the self-sealing rod and the self-control film are reset under the action of respective spring force, and the switch handle is reset along with the self-sealing rod and the self-control film, so that the oil outlet function is recovered.
At present, because the quality of nozzle differs and refueller's level is different, the nozzle leaks out the oil body easily at the refueling in-process, especially when inserting or extracting the nozzle, and the oil body is too much reveals the environment that can bring the potential safety hazard for filling station, consequently, needs an oil leak state monitoring mechanism, can effectively discern above-mentioned sight and take corresponding safety countermeasure in order to make things convenient for filling station management side.
