    The self-sealing Fuel nozzle is a refueling nozzle with an automatic closing function. When the oil is filled with the container, the Fuel nozzle valve can be automatically closed to keep the oil from overflowing, making the refueling site cleaner and safer.

    Fuel nozzle working principle

    When the oil dispenser is supplying oil, the main valve is opened, and the pressure oil enters the oil cavity where the main and auxiliary valves are located in the gun body, pushes open the auxiliary valve against the spring force, and is discharged through the nozzle of the oil gun. The flow of oil reduces the static pressure, and the pressure in the upper cavity of the switch membrane decreases accordingly. The air inlet at the front end of the oil gun nozzle is in communication with the atmosphere, the pressure of the upper chamber and the lower chamber of the switch membrane are equal (both equal to the atmospheric pressure), and the switch membrane is in a balanced position.
    When the oil floods the air intake nozzle and the upper cavity of the switch membrane are isolated from the outside atmosphere to form a negative pressure, the lower cavity of the switch membrane still maintains atmospheric pressure, so that a pressure difference ΔP is formed between the upper and lower cavities of the switch membrane, and the switch membrane is out of balance. When the self-sealing rod moves up, the self-control rod moves down under the pulling force of the switch handle, the steel ball is squeezed into the hole of the self-control rod, the switch handle moves down due to the loss of the fulcrum, the main valve is closed, and the oil supply stops.

    Fuel nozzle use and maintenance

    When using the self-sealing fuel nozzle, be careful to handle it with care, and the main valve ejector should be frequently filled with lubricating oil to ensure flexible and reliable action.
    Pay attention to keeping the oil and gas paths in the self-sealing fuel nozzle unblocked to prevent debris from blocking the oil and gas paths, so as to avoid the failure of the self-sealing function.
    Although the self-sealing fuel nozzle has the function of automatically stopping the oil supply after filling the container, the staff should not stay away from the scene when using it to avoid accidents.

    Troubleshooting and troubleshooting of self-sealing fuel nozzle
    Trouble phenomenon Cause Removal method
    Self-sealing failure
    1. There is tiny dirt in the depression of the needle roller of the rubber diaphragm and the self-control lever
    2. There is a foreign object stuck at the auxiliary valve
    2.1 Open the measuring cover, and take out the rubber diaphragm for cleaning
    2.2 Remove the oil outlet pipe and take out the auxiliary valve to remove foreign matter.
    Self-sealing is too sensitive There are foreign objects in the ventilation hole of the auxiliary valve Remove the oil outlet pipe and clean the ventilation hole of the auxiliary valve.
    Oil leakage at the ejector rod Sealing ring failure Replace.
    No oil The auxiliary valve is stuck (usually occurs at the first startup after a long period of shutdown) Remove the oil outlet pipe, take out the auxiliary valve, and then check the joint between the oil outlet hole of the fuel nozzle body and the auxiliary valve.
    No burrs, just reinstall after removing the burrs.
    After the nozzle is turned off, there is still a small amount of oil flowing out of the oil outlet pipe, which cannot be closed immediately. The auxiliary valve is stuck by foreign objects. Same as above
    The fuel nozzle is hung on the machine and the oil still overflows from the oil outlet pipe The main valve is worn or blocked by foreign objects Open the main valve, take out the main valve to replace the rubber gasket, or remove foreign objects.
