As shown in FIGS. 1 to 4, the embodiment of the utility model discloses a fuel truck nozzle, this fuel truck nozzle includes: gun body 10, barrel, stop valve 20, ram 40, spring 30, and bead 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 check valve 20 is disposed above the platform 13, as shown in fig. 2, when the check valve 20 is pressed against the platform 13, the liquid passing port 14 is blocked, the oil inlet passage 11 and the oil outlet passage 12 are blocked, which makes the fuel gun in a closed state, as shown in fig. 4, when the check valve 20 is moved upward, the liquid passing port 14 is opened, the oil inlet passage 11 is communicated with the oil outlet passage 12, and the fuel in the oil inlet passage 11 can flow into the oil outlet passage 12 through the liquid passing port 14, so that the fuel gun is opened, thereby enabling the fuel to be injected into the fuel tank of the vehicle through the 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 spring 30 is disposed above the check valve 20 for pressing the check valve 20, and when the check valve 20 is not subjected to the upward force of the plunger 40, the spring 30 presses the check valve 20 against the platform 13 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 ejector rod 40, as shown in fig. 4, 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 against the ejector rod 40 to move upwards, the ejector rod 40 drives the stop valve 20 to move upwards to enable the liquid passing port 14 to be opened, and the spring 30 is compressed, as shown in fig. 2, and after the operator removes the force on the pressing strip 50, the spring 30 resets to enable the stop valve 20 to move downwards again to block the liquid passing port 14. In the present embodiment, the stopper valve 20 is provided in the following structure:
the stop valve 20 includes a body in the shape of a flat column and a frustum 22 formed below the body 21, and the area of the cross section of the frustum 22 is gradually reduced from top to bottom.
The advantages of the above embodiment are: because the frustum 22 is arranged on the main body 21 of the stop valve 20, the opening degree of the liquid passing port 14 is limited by the outer peripheral surface of the frustum 22 and the liquid passing port 14 together, so that when the stop valve 20 moves upwards by the aid of the ejector rod 40 through the pressing strip 50, the opening degree of the liquid passing port 14 is gradually increased, and thus, the opening degree variation of the liquid passing port 14 caused by unit displacement of the stop valve 20 can be more reasonable by arranging the axial size and the taper of the frustum 22, for example, the opening degree variation of the liquid passing port 14 caused by unit displacement of the stop valve 20 can be smaller by increasing the axial size of the taper sleeve and reducing the taper, so that the situation that the opening degree of the liquid passing port 14 is instantly increased to the maximum when the pressing strip 50 rotates by a small amount can be avoided, and an operator can conveniently control the filling flow rate of fuel.
In a preferred embodiment of the present invention, as shown in fig. 2, a plug 60 is disposed at a position vertically opposite to the stop valve 20 of the gun body 10, a spring 30 is disposed between the plug 60 and the stop valve 20, and the plug can be mounted on the gun body 10 by screwing. In this embodiment, the spring 30 can be replaced by detaching the plunger from the gun body 10.
In a preferred embodiment of the present invention, as shown in fig. 2, the liquid passing port 14 extends downward by a certain amount 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 present invention, as shown in fig. 2, a sealing ring 70 is provided on the platform 13 for the main body 21 to press against. 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.
