Abstract
A fuel refueling gun includes a gun pipe, a gun body, a trigger and a protecting bow. The gun body is provided with a gun body cover below which is provided with a main spring below which is provided with a lifting valve assembly whose ejector rod is connected to the trigger assembly. In order to reduce the work strength of the refueling workers as well as to prolong the service life of the refueling gun and to avoid the problem that the pressure of the liquid fuel is overcome at one time, the refueling gun of the utility model is improved on a secondary-level main valve of the original gun body assembly and increased another-level or more levels of valves which will be opened level by level, thus the liquid pressure of the liquid fuel is reduced and the purpose is reached. The utility model is suitable for the filling of all liquid fuels and is especially used on the refueling gun of the fuel station.
Description
Technical field
The utility model belongs to a kind of liquid fuel nozzle, the nozzle that uses on particularly a kind of petrol service station fuel charger.
Background technology
At present, the nozzle that petrol service station uses all uses the one valve door.The nozzle of one valve door in use, because of the rear end fluid fuel has certain hydraulic coupling, the refueling operation personnel need the disposable hydraulic coupling that overcomes fluid fuel when opening this type of nozzle, it is very painstaking usually can to feel after working long hours.And when nozzle was self-styled, main valve closed the pipeline of closing to the nozzle rear end and produces an instantaneous high pressure anti-force, can influence the normal working of other elements in the pipeline, reduces its service life.
The utility model content
The purpose of this utility model: be to provide a kind of and can alleviate the refueling operation personnel labor intensity, make nozzle operation light, and make the nozzle fuel nozzle that reduces of pipeline high pressure recoil in use.Thereby guarantee that nozzle is former, the device mode of operation is normal, service life is higher.
In order to achieve the above object, the utility model adopts following technical scheme.A kind of fuel nozzle, comprise gun barrel, rifle body, trigger, protect bow, one rifle body lid is set above the rifle body, main spring of underlying, adjacent main spring below device has poppet valve, and a push rod is arranged in the cavity of this one-level poppet valve, and an end is near poppet valve, so that withstand poppet valve when opening oil circuit, make its unlatching; The other end of push rod then is movably connected on the trigger.Unlike the prior art be, on the basis of former one-level poppet valve, the utility model also increases a two-stage hoisting valve, makes to promote refueling operation branch two-stage or multistage finishing, the two-stage hoisting valve is installed with the one-level poppet valve is concentric, and places the outer ring.Promote action in order to finish, push rod is provided with boss.
Because this nozzle is divided into one-level poppet and secondary valve with the main valve assembly, when nozzle is opened, its secondary valve is opened earlier, because the area of the axial motion direction of secondary valve is littler than main valve in the original design, according to the uniform and equal principle of liquid pressure, open the required fluid pressure that overcomes of secondary valve and just reduce in proportion than the area of the required fluid pressure that overcomes of the structure of former main valve according to the axial motion direction.Opening secondary valve behind the door, nozzle is started working, and liquid fuel sprays from the nozzle gun barrel.Continue upwards to buckle trigger again, the one-level valve can be opened, this moment is because the secondary valve is opened, the hydraulic coupling that liquid fuel acts on the secondary valve is released, opening the required fluid pressure that overcomes of one-level valve is that the hydraulic coupling of the axial motion direction that main valve bore of original design deducts the hydraulic coupling of the axial motion direction of secondary valve.Thereby reach the purpose that in whole nozzle opening procedure, reduces the required hydraulic coupling that overcomes.Equally, when nozzle was closed, the one-level valve can be closed earlier, and the secondary valve is closed after the meeting.So when closing the one-level valve in the fuel charger pipeline formed high pressure anti-force, can before the secondary valve closing, being released a part.So, when the secondary valve closing, formed instantaneous high pressure anti-force will reduce much in the fuel charger pipeline, thereby prolongs the service life of other elements in the pipeline.
The change of nozzle structure, the effect of particularly original poppet valve is divided into the two-stage hoisting valve and finishes, because above-mentioned, operation is seemed easily, has alleviated labour intensity greatly, and makes that nozzle is former, device improves service life.
Description of drawings
Fig. 1: the structural representation of the utility model embodiment;
The local structure enlarged drawing of Fig. 2: Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The described fuel nozzle of present embodiment comprises gun barrel 1, rifle body 2, trigger 3 and protects bow 4.Having a rifle body lid 2.2 to push down other part of main spring 2.3 and other in the rifle body 2 is also fixed.Main spring 2.3 is installed in rifle body lid 2.2 times, generally makes with spring steel, and main spring is with one-level poppet valve 2.1.1 for 2.3 times, and poppet valve 2.1.1 available metal material or engineering plastics are made.At the inner chamber concentric position of two-stage hoisting valve 2.1.1, be equipped with a push rod 2.4, the one end contacts with two-stage hoisting valve 2.1.1 with rational gap; The other end and trigger 3 are rotationally connected.One-level poppet valve 2.1.2 is arranged on the periphery of two-stage hoisting valve 2.1.1, can be designed to circular or square or with the supporting shape of rifle body 2, general and two-stage hoisting valve 2.1.1, the push rod 2.4 same centers of circle, push rod 2.4 is provided with boss 2.4.1 and opens to promote this valve in the position near one-level poppet valve 2.1.2 bottom.The sealing of one-level poppet valve 2.1.2 and main valve oil inlet is very important, so oil inlet 2.5 upper design become the boss shape, and with the corresponding contact position of one-level poppet valve 2.1.2, impose seal ring.
When using the utility model, hold the rear end of fuel nozzle rifle body 2 earlier, fasten trigger 3 with finger, make trigger 3 upward movements, drive push rod 2.4 upward movements that are rotationally connected with trigger 3,2.1.1 upwards backs down with the two-stage hoisting valve, and nozzle is started working, fuel oil with A to inflow, by B to refueling.When push rod 2.4 continuation upward movements, push rod boss 2.4.1 is with one-level poppet valve 2.1.2 jack-up, and the fuel nozzle is finished whole actions, the normal oiling.
