As shown in FIG. 1 and FIG. 2, the embodiment of the utility model discloses a fuel truck nozzle, this fuel truck nozzle includes: the gun body 10, the gun barrel, the stop valve 20, the ejector pin 40, the first permanent magnet 31, the second permanent magnet 32, and the compression bar 50. An oil inlet channel 11 and an oil outlet channel 12 are formed in the gun body 10, a platform 13 is formed between the oil inlet channel 11 and the oil outlet channel 12, a liquid passing port 14 used for communicating the oil inlet channel 11 and the oil outlet channel 12 is formed in the middle of the platform 13, and the liquid passing port 14 is used for communicating the oil inlet channel 11 and the oil outlet channel 12. A barrel (not shown in the drawings) is connected to the front end of the oil outlet passage 12, and a hose of the fuel dispenser is connected to the rear end of the oil inlet passage 11. The stop valve 20 is arranged above the platform 13, when the stop valve 20 is pressed against the platform 13, the liquid passing port 14 is blocked, the oil inlet channel 11 and the oil outlet channel 12 are blocked, so that the fuel gun is in a closed state, when the stop valve 20 moves upwards, the liquid passing port 14 is opened, the oil inlet channel 11 is communicated with the oil outlet channel 12, and fuel in the oil inlet channel 11 can flow into the oil outlet channel 12 through the liquid passing port 14, so that the fuel gun is opened, and the fuel can be injected into a fuel tank of the vehicle through a gun barrel. The upper end of the stem 40 is vertically connected to the check valve 20 and is located below the check valve 20, and the lower end of the stem 40 protrudes out of the gun body 10. The first permanent magnet 31 is arranged on the stop valve 20, the second permanent magnet 32 is arranged at a position where the gun body 10 is opposite to the first permanent magnet, the homopolar poles of the first permanent magnet 31 and the second permanent magnet 32 are opposite, and when the stop valve 20 is not subjected to the upward force of the ejector rod 40, the stop valve 20 is pressed against the platform 13 by virtue of the magnetic repulsion force between the first permanent magnet 31 and the second permanent magnet 32 so as to block the liquid passing port 14. The pressing strip 50 is movably connected to the gun body 10, the front portion of the pressing strip 50 is located below the push rod 40, when an operator applies force upwards on the pressing strip 50 to enable the front portion of the pressing strip 50 to rotate upwards, the pressing strip 50 pushes the push rod 40 to move upwards, the push rod 40 drives the stop valve 20 to move upwards to enable the liquid passing port 14 to be opened, and after the operator cancels the force on the pressing strip 50, magnetic repulsion force between the first permanent magnet 31 and the second permanent magnet 32 enables the stop valve 20 to move downwards again to block the liquid passing port 14.
The advantages of the above embodiment are: the stop valve 20 is pressed against the platform 13 by the magnetic repulsion force between the two permanent magnets to block the liquid passing port 14, and the magnetic action of the permanent magnets has a longer effective period compared with that of a spring, and fatigue damage caused by frequent use does not occur like the spring, so that the stop valve 20 has a longer service life, and the function of blocking the liquid passing port 14 by the stop valve 20 is more reliable.
In a preferred embodiment of the present invention, a plug 60 is disposed at a position vertically opposite to the stopper valve 20 of the gun body 10, and the second permanent magnet 32 is disposed at a lower end of the plug 60. In this embodiment, the spring can be replaced by detaching the plunger from the gun body 10.
In a preferred embodiment of the present invention, the liquid passing port 14 extends downward to form a liquid passing hole 15. In the present embodiment, the liquid passing hole 15 has a converging effect on the fuel to prevent the fuel from splashing or being injected in all directions when passing through the liquid passing port 14 after the liquid passing port 14 is opened.
In a preferred embodiment of the invention, as shown in fig. 2, the platform 13 is provided with a sealing ring 70 against which the stop valve is pressed. In this embodiment, the sealing ring 70 seals the stop valve 20 with the platform 13, thereby preventing a small amount of fuel from leaking through the liquid passing port 14 when the liquid passing port 14 is in a closed state.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
