Description
Technical field
The present invention relates to Investigation of Petroleum Vapor Recovery Technology fields, and in particular to a kind of petroleum vapor recovery dust cover.
Background technology
Since gasoline is very easy to volatilization, so gas station is easy to be filled with " oily taste ".These oil gas largely evaporate simultaneously
It is directly discharged in air, not only causes serious quantity loss and quality to decline, but also seriously polluted atmospheric environment, with
And leave great security risk.Country forces to carry out installation device for recovering oil and gas in gas station, and storage tank farm is determined, refuels
Exhaust of oil of standing controls standard and implements region and time and exhaust of oil limit value.
The gasoline vapor generated in refueling process is gas station's one of main problem to be solved.Existing refueling nozzle uses
Gas gathering mask be Conch type, smaller mouth hoop on the petroleum vapor recovery gun barrel of refueling nozzle, the other end refuel when be bonded with oil filler,
But existing gas gathering mask is common rubber material, the poor sealing between vehicle oil filler, the dust floated in air
Equal impurity can enter gas recovery system for oil by gas gathering mask, reduce the quality of recycling oil gas, meanwhile, after refueling nozzle is pulled out, table
The oil droplet of face remnants cannot be introduced into gas gathering mask, can evaporate into air.
Invention content
It is an object of the invention to overcome poor sealing between existing refueling nozzle gas gathering mask and vehicle oil filler, in air
The impurity such as the dust of floating can enter gas recovery system for oil by gas gathering mask, reduce the quality of recycling oil gas, meanwhile, refueling nozzle pulls out
After out, the problem of oil droplet of surface residual cannot be introduced into gas gathering mask, a kind of petroleum vapor recovery dust cover is provided, the recycling dust cover
Dust, while good airproof performance can be filtered, ensures that most vaporizing oil-gas can enter recovery system.
The present invention is realized using technical solution below：
A kind of petroleum vapor recovery dust cover, on refueling nozzle, the petroleum vapor recovery dust cover includes fixed section and telescopic segment,
One end of fixed section is osculum, and the other end is big mouth, and annular groove is arranged on the outer wall of osculum, clip is arranged in annular groove；Big mouth
It is tightly connected with telescopic segment, filter membrane is arranged in junction；The telescopic segment includes telescoping tube and the spring that is arranged on the outside of telescoping tube,
One end of spring is fixedly connected with fixed section, and the other end is fixedly connected with the free end of telescoping tube, the initial length of spring with stretch
The initial length of the draw is identical, and the compression length of spring is less than the length of the petroleum vapor recovery gun barrel of refueling nozzle；The telescoping tube
Free end is in bell mouth shape.
Further, snap ring is fixedly installed on the outer wall of the free end of the telescoping tube, spring is fixedly connected with snap ring.
Further, the fixed section is formed by two layers, and internal layer is rubber layer, outer layer is hard material layer；
Further, the material of the telescoping tube is rubber.
Petroleum vapor recovery dust cover provided by the invention has the advantages that：(1) dust cover and vehicle oil filler it
Between good airproof performance, can ensure the overwhelming majority vaporizing oil-gas enter recovery system；It (2) can be by dust floated in air etc.
Contaminant filter falls, and avoids enter into gas recovery system for oil, ensures the quality of recycling oil gas；(3) after refueling nozzle is pulled out, surface residual
Oil droplet can enter recovery system.

Specific implementation mode
In order to which the above objects, features and advantages of the present invention is more clearly understood, below in conjunction with the accompanying drawings and implement
The present invention will be further described for example.It should be noted that in the absence of conflict, in embodiments herein and embodiment
Feature can be combined with each other.
Embodiment
The present embodiment provides a kind of petroleum vapor recovery dust covers, for replacing traditional gas gathering mask in refueling nozzle.Such as Fig. 1
Shown, which is on the whole up-small and down-big tubular, and middle part bends certain angle.The recycling dust cover specifically wraps
Fixed section 1 and telescopic segment 2 are included, one end of fixed section 1 is osculum, and the other end is big mouth, and annular groove 11 is arranged on the outer wall of osculum,
Clip is set in annular groove 11, and clip can select existing structure, be not shown in figure, and by clip, fixed section hoop is refueling
On the petroleum vapor recovery gun barrel of rifle.Big mouth is tightly connected with telescopic segment 2, and filter membrane 3 is arranged in junction, and filter membrane is to allow oil gas molecule logical
Cross without allow dust impurity by filter membrane, can by dust keep off except gas recovery system for oil, ensure enter recovery system
Oil gas it is pure.
Telescopic segment 2 includes telescoping tube 21 and the spring 22 for being symmetricly set on the outside of telescoping tube 21, one end of spring 22 with it is solid
Determine section 1 to be fixedly connected, the other end is fixedly connected with the free end of telescoping tube 21, the initial length of spring 22 and telescoping tube 21 just
Beginning length is identical, i.e., in the state of spring nature, telescoping tube 21 also can be in nature.The length of telescoping tube 21 is preferably big
In the length of the fuel-displaced gun barrel of refueling nozzle so that after oiling, telescoping tube 21 can cover fuel-displaced gun barrel completely, make residual
Oil gas on fuel-displaced gun barrel can enter recovery system, avoid all evaporateing into air.The compression length of spring 22 is less than
The length of the petroleum vapor recovery gun barrel of refueling nozzle, when ensureing to refuel, spring 22 is to shrink, and the spring 22 of contraction can be to vehicle oil filler
Thrust is generated, to make the free end of telescoping tube 21 closely be attached on oil filler.In order to make telescoping tube 21 preferably and oil filler
The free end of fitting, telescoping tube 21 is in bell mouth shape, and uses corrosion resistant rubber material, as shown in Figure 3.
When in order to ensure spring contraction, the free end of telescoping tube 21 will not have an impact the deformation of sealing performance, telescoping tube
Snap ring 23 is fixedly installed on the outer wall of 21 free end, spring 22 is fixedly connected with snap ring 23.
In order to extend the service life of petroleum vapor recovery dust cover, fixed section 1 is formed by two layers, and internal layer is corrosion resistant rubber
Glue-line, outer layer are hard material layer, such as engineering plastics or stainless steel.
In the present invention unless specifically defined or limited otherwise, the terms such as term " connection ", " connected " should all do broad sense
Understand, for example, it may be fixedly connected, may be a detachable connection or integrally connected；It can make to be directly connected to, can also lead to
Intermediary is crossed to be indirectly connected with.For the ordinary skill in the art, above-mentioned term can be understood as the case may be
Concrete meaning in the present invention.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the scope of the present invention
It is defined, under the premise of not departing from design spirit of the present invention, those of ordinary skill in the art are to technical scheme of the present invention
The various modifications made and improvement should all be fallen into the protection domain of claims of the present invention determination.
