Background technology
At present, most of petrol service station during to automobile fuel filler, all adopts common Self-closing oil feeder, and this nozzle has the function that can automatically close when the fuel tank of automobile is filled it up with oil.Its structure is mainly comprised of rifle body, oil inlet passage, main valve, control cock, reflux valve, oil pipe and Handleset, and main valve is arranged in oil inlet passage, and its on off state is controlled by the location status of Handleset.The end of the valve rod of control cock is connected with one end of handle, the up-and-down movement of valve rod is controlled by controlling diaphragm, control diaphragm chamber above diaphragm being communicated with to pore by through hole on rifle body and on gun barrel and oil pipe front end, and be communicated with oil pipe internal channel by rifle body, in refueling process, the negative pressure that You Liudui diaphragm chamber produces is given the air pressure balance of pore inspiration, when fuel tank is filled it up with oil, oil pipe front end give pore by by stopping up, the negative pressure that You Liudui diaphragm chamber produces is inhaled the moving diaphragm of controlling, and be with on brake control valve valve rod and move, change the location status of Handleset, main valve is closed, realize self-sealing function.
But this Self-closing oil feeder, can only could realize self-sealing function when fuel tank is filled it up with oil, and structure is more complicated, so it is very inconvenient to operate, thereby has increased to a certain extent production and the use cost of nozzle; In addition, while causing gun barrel to come off from automotive oil tank due to staff's misoperation, carelessness or other reasons, there will be nozzle outwards to continue the phenomenon of leakage of oil, this not only causes the waste of oil product, and can bring potential safety hazard to petrol service station.
Utility model content
The purpose of this utility model is to overcome the defect of prior art, provides a kind of oil gas to reclaim nozzle gun barrel, by setting up layback from sealing assembly in gun barrel, has realized gun barrel layback self-sealing function.
For achieving the above object, the utility model proposes following technical scheme: a kind of oil gas reclaims nozzle gun barrel, it comprises body, be arranged on oil pipe in body, from tube sealing, oil connector and reflux valve, described oil pipe one end is fixedly connected with described reflux valve by ring seat joint, the other end is connected with described oil connector, described, from tube sealing, near one end connection of reflux valve, swing back from sealing assembly, described layback comprises the housing of hollow and is arranged on locations, the ball in housing from sealing assembly, and described locations is fixedly installed in housing.
Preferably, described in tube sealing is arranged on oil pipe.
Described housing one end is connected from tube sealing with described, and the other end is air extractor duct, and described self-styled pipe is used at refueling process input air, the pressure in balance oil pipe.
When described oil pipe is during in oil transportation state, described ball locks on described locations, from the normal input air of tube sealing.
When described layback is when sealing assembly inclination 45～60 is spent, the outer circumference surface of described ball and the internal face of described air extractor duct fit, and block air extractor duct, now the gas circuit in tube sealing is cut off, in oil pipe, be negative pressure state, stop gasoline output, reach self-styled effect.
Describedly from tube sealing, near oil connector one end, stretch out outside oil pipe and with described body and be interlinked to the outside, for input air.
Described reflux valve is provided with a ring seat outward.
The beneficial effects of the utility model are: (1) the utility model is simple in structure, easy to operate, can be under there is the unforeseen circumstances that gun barrel comes off from fuel tank, realize self-styledly, avoid occurring the potential safety hazards such as nozzle leakage of oil, improved the safety in utilization of nozzle.

The specific embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical scheme of the utility model embodiment is carried out to clear, complete description.
As shown in Figure 1, a kind of oil gas that the utility model discloses reclaims nozzle gun barrel, by setting up layback from sealing assembly 5 in gun barrel, has realized nozzle gun barrel layback self-sealing function.Described nozzle gun barrel comprises body 1, be arranged on oil pipe 2 in body 1, oil connector 3, from tube sealing 4, layback from sealing assembly 5, reflux valve 7 and ring seat 8, described oil pipe 2 one end are connected with described oil connector 3.Described oil pipe 2 other ends are fixedly connected with described reflux valve 7 by ring seat joint 6, and are further connected with the transfer line (not shown) of oil product by reflux valve 7.On described reflux valve 7, ring seat 8 is installed, when normal fueling state, described reflux valve 7 is opened under the punching press of gasoline, communicates with oil pipe 2.
It is described in tube sealing 4 is arranged on oil pipe 2, one end is stretched out oil pipe 2 and is communicated with the air extractor vent 9 on body 1, for input air from body 1, the other end is fixedly connected with from sealing assembly 5 with described layback, described layback from sealing assembly 5 for cutting off the input from tube sealing 4 interior air, thereby make to be negative pressure state in oil pipe 2, stop refueling.
Described layback comprises the housing 51 of hollow and is arranged on locations 52, the ball 53 in housing 51 from sealing assembly 5, described locations 52 is fixedly installed on housing 51 inwalls, described housing 51 one end with from tube sealing 4, communicate, and both closely connect, the other end is air extractor duct 54, described air extractor duct 54 stretches to reflux valve 7, the other end of the present embodiment middle shell 51 is designed to funnel-form, be convenient to ball 53 and block rapidly air extractor duct 54, certainly in other embodiment of the present utility model, also ball 53 can be designed to other shapes, as long as can be blocked air extractor duct 54.
When gun barrel is in fueling state lower time, described ball 53 locks on described locations 52, when there is the unforeseen circumstances that gun barrel comes off from fuel tank, gun barrel is lifted, described layback is from sealing assembly 5 during horizontal by 45 °～60 ° of angles, ball 53 departs from from locations 52, be slipped to air extractor duct 54 places of described housing 51, block air extractor duct 54, now the internal face of the outer circumference surface of ball 53 and described air extractor duct 54 fits, in oil pipe 2, be negative pressure state like this, realize self-styled, avoided the generation of the unforeseen circumstancess such as nozzle leakage of oil, improved the safety in utilization of nozzle.
Between described body 1 and described ring seat joint 6, be provided with seal ring 10, generally adopt O RunddichtringO, make to connect tightr between the two.
From air extractor duct 54 sides of described housing 51, extend a vacuum lamp 11; be interlinked to the outside with body 1; for normally filling it up with under oil condition in fuel tank; realize self-styled; because under fuel tank is filled it up with oil condition; gasoline can be blocked its vacuum lamp 11 mouths of pipe, realizes self-styledly from tube sealing, does not need people for operating; Therefore the utility model the unexpected situation such as can come off at gun barrel while occurring from fuel tank, and when coming off, gun barrel is elevated, and nozzle moment realizes self-styledly, can effectively avoid the generation of the contingencies such as leakage of oil.
Technology contents of the present utility model and technical characterictic have disclosed as above; yet those of ordinary skill in the art still may be based on teaching of the present utility model and announcements and are done all replacement and modifications that does not deviate from the utility model spirit; therefore; the utility model protection domain should be not limited to the content that embodiment discloses; and should comprise various do not deviate from replacement of the present utility model and modifications, and contained by present patent application claim.
