Abstract
The utility model discloses a nozzle with rifling, including the rifle body with the handle components of rifle body coupling, go out oil pipe, be equipped with the rifling on the play the inner wall of the oil tubing. The utility model discloses an at the rifling that an oil pipe set up, can make out the oil of exporting concentrate out the orificial mid portion of oil pipe on among the oil pipe to have and improve the fast effect of oil stream, make the oil of output have better directionality, even under the less condition of oil stream volume, the phenomenon that also can not appear splashing. The rifling pitch design of gradual change formula makes out oil pipe's entry have great pitch, and the export that goes out oil pipe is provided with less pitch, can increase out the velocity of flow of oil pipe petroleum company of the people's republic of china gradually, and guarantees the steady output of oil.
Description
Technical field
The utility model belongs to topping up device technical field, relates to a kind of nozzle, more specifically, relates to a kind of nozzle with rifling.
Background technology
Nozzle is the terminal that in petrol service station, fuel charger exports, and namely contacts the part of automotive oil tank.Mainly contain self-sealing refueling gun and combined type nozzle two kinds at present.In the process using oil gun to refuel, due to the existence of nozzle port inductor, there will be " jumping rifle " phenomenon when pasta rises and touches inductor.In order to avoid when being about to fill it up with oil, pasta and sensor contacts cause jumping rifle, in use nozzle refueling process, usually can oil gun being carried to reservoir port, the phenomenon of dispersion or splashing when at this time often causing oil gun mouth fuel-displaced.To trace it to its cause be owing to can not concentrate from oil pipe oil out, and oily flow velocity is relatively low causes, and all there is the phenomenon of oil dispersion or splashing in existing two kinds of nozzles.
Summary of the invention
The utility model discloses a kind of nozzle with rifling, rifling is set in nozzle oil outlet pipe, solve out the problem of oil dispersion, splashing.
In order to reach above object, the utility model provides following technical scheme:
Have a nozzle for rifling, the Handleset, the oil outlet pipe that comprise rifle body and be connected with rifle body, described oil outlet pipe inwall is provided with rifling.
Further, described rifling diminishes gradually along fuel-displaced direction pitch.
Further, described rifling is convex rifling.
Further, described rifling becomes large gradually along fuel-displaced direction height.
Further, described rifling is recessed rifling.
Further, described rifling diminishes gradually along the fuel-displaced direction degree of depth.
Further, described oil outlet pipe has bending part, and outside described bending part, rifling pitch is less than inner side rifling pitch.
Further, described rifling dextrorotation or inverse to revolve.
Compared with prior art, the utility model tool has the following advantages and beneficial effect:
1. the rifling by arranging at oil outlet pipe, the oil exported in oil outlet pipe can be made to concentrate on the centre portion of the oil outlet pipe mouth of pipe, and be improved the effect of oily flow velocity, make the oil exported have good directivity, even if when oily flow is less, also there will not be the phenomenon of splashing.
2. the rifling pitch design of gradual change type makes the entrance of oil outlet pipe have larger pitch, and the outlet of oil outlet pipe is provided with less pitch, can strengthen the flow velocity of oil in oil outlet pipe gradually, and ensures the steady output of oil.
3. the gradual change design of rifling height or the degree of depth, can increase Extraction rate further, thus make fuel-displaced more concentrated, avoids splashing.
4. rifling design can be arranged in existing Self-closing oil feeder and combined type nozzle, all has good result, has wide range of applications.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, following detailed description of the invention should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.
Embodiment one:
Refer to Fig. 1, nozzle in figure has and comprises rifle body 1, Handleset 2, oil outlet pipe 3, Handleset 2 is fixed on rifle body, oil outlet pipe 3 is arranged on rifle body one end and is communicated with rifle body inside, oil outlet pipe 3 one of being connected with rifle body 1 is oil inlet end 3-1, one away from rifle body is oil outlet end 3-2, and oil outlet pipe 3 inwall is provided with rifling 4.When oil is after rifle body 1 enters oil inlet end 3-1, accelerate gradually under rifling effect in oil outlet pipe 3, from oil outlet end 3-2 export the obvious flow velocity of oil accelerate and more concentrated.
Specifically, rifling can be dextrorotation or inverse revolving, and all has good result.
Embodiment two:
In order to be lifted out speed oil further, as the improvement of embodiment one, the pitch of rifling 4 adopts progressive design, namely pitch from oil inlet end 3-1 to oil outlet end 3-2(namely along fuel-displaced direction) diminish gradually, as shown in Figure 2, be section drawing a bit of in oil inlet in figure, wherein left side is oil inlet end 3-1 direction, right side is oil outlet end 3-2 direction, d1>d2>d3.Compared with the nozzle in embodiment one, the nozzle Extraction rate adopting gradual pitch to design promotes and reaches 10%-30%.
Embodiment three:
Preferred as embodiment one or embodiment two, the rifling 4 in oil outlet pipe 3 protrudes from oil outlet pipe inner wall surface, forms convex rifling.In this kind of situation, as shown in Figure 3, rifling from oil inlet end 3-1 to oil outlet end 3-2(namely along fuel-displaced direction) become large highly gradually, speed oil can be lifted out further through test, and improve fuel-displaced concentration degree.It should be noted that, the ratio in figure between rifling height and oil outlet pipe caliber, wall thickness is not as restriction of the present utility model, and in fact, in order to represent clear in the drawings, the aspect ratio of rifling is more outstanding.
Embodiment four:
Preferred as embodiment one or embodiment two, the rifling 4 in oil outlet pipe 3 is spiral groove, forms recessed rifling.In this kind of situation, as shown in Figure 4, described rifling from oil inlet end 3-1 to oil outlet end 3-2(namely along fuel-displaced direction) degree of depth diminishes gradually, speed oil can also be lifted out further through test, and improve fuel-displaced concentration degree, have close effect with embodiment three.It should be noted that, the ratio in figure between rifling height and oil outlet pipe caliber, wall thickness is not as restriction of the present utility model, and in fact, in order to represent clear in the drawings, the degree of depth of rifling is deeply actual, and rangeability is also larger.
Embodiment five:
Because oil outlet pipe has bending part 3-3 usually, through overtesting, we find, outside oil circuit, flow velocity can slightly larger than inner side flow velocity, this can make the fuel-displaced of oil outlet end present uneven phenomenon, therefore as the improvement of embodiment one, as shown in Figure 5, this place is designed to outside rifling pitch and is less than inner side rifling pitch by further, makes in fuel-displaced more stationary set.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned embodiment, also comprises the technical scheme be made up of above technical characteristic combination in any.It should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle, can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
