Abstract
The utility model provides a nozzle barrel with anti -drip oil structure, is provided with in the play oil pipe and proclaims oneself the trachea including going out oil pipe, it has a glissile segment to proclaim oneself tracheal middle part, and glissile segment swing joint has a dead weight valve plug, and the dead weight valve plug can slide from top to bottom in glissile segment department, is provided with the seal receptacle on the play oil pipe of dead weight valve plug lower part, seal receptacle and/or dead weight valve plug are made by magnetic material, and the seal receptacle is inhaled with dead weight valve plug magnetism mutually. When refueling, the valve open of nozzle, the oil promotes the dead weight valve plug under the pressure effect, and the oil passes through from the space of conducting oneself with dignity the valve plug and go out between the oil pipe inner wall. Finish when refueling, when the valve of nozzle is closed, lift up the oil gun, defeated oil pipe up, the dead weight valve plug is because of dead weight erroneous tendency seal receptacle, and is sealed because of the magnetic action actuation, forms the check valve structure, the oil drips to on the ground when preventing next time from to extract the nozzle and refueling. Have advantages such as the oil loss is low, low in the pollution of the environment, performance safe and reliable.
Description
Technical field
The utility model relates to a kind of nozzle gun barrel, relates to a kind of gun barrel increasing oil drip-preventing function specifically.
Background technology
At present, when petrol service station is to automobile fuel filler, most petrol service station all adopts common self-sealing refueling gun, and oil gun gun barrel generally comprises oil outlet pipe and is arranged on the self-styled tracheae in oil outlet pipe, self-styled valve, oil outlet pipe seal ring.Oil outlet pipe is fixedly connected with the reflux valve in rifle body, is connected not tight, is easy to produce gap in existing gun barrel between oil outlet pipe with reflux valve.In refueling process, oil in oil outlet pipe enters in oil outlet pipe and rifle body from this gap, nozzle is after main valve closes oiling stopping, from automotive oil tank, oil gun is extracted, when lifting oil gun gun barrel or nozzle hung on fuel charger, due to Action of Gravity Field, it is inner that the residual oil product in oil outlet pipe and rifle body can remain in oil gun rifle body.Until next time from fuel charger mention oil gun prepare to fuel tank refuel and when oil gun gun barrel down time, Action of Gravity Field make inner product oil along gun barrel outflow muzzle, drop onto on ground.
Current increasing Reconstruction of Service Stations is self-service or semi-self-service petrol service station, and during normal driver self-service refueling can not as specialty oiling person strict operation nozzle, rifle body inner product oil droplet is caused to fall, and then cause oil product to lose and environmental pollution, cause direct environmental issue and economic problems, also can work the mischief to the physical and mental health of gas station attendant, can potential safety hazard be caused, the subject matter of existing nozzle existence that Here it is.
Utility model content
Fall to causing the problem of oil product loss and environmental pollution to solve rifle body inner product oil droplet in prior art, the utility model provides a kind of nozzle gun barrel with oil drip-preventing structure.
A kind of nozzle gun barrel with oil drip-preventing structure, comprise oil outlet pipe, the oil outlet of oil outlet pipe is upper end, be provided with self-styled tracheae in oil outlet pipe, there is glissile segment at the middle part of described self-styled tracheae, and glissile segment is connected with deadweight valve plug, deadweight valve plug can slide up and down on glissile segment, the oil outlet pipe place of deadweight valve plug bottom is provided with seal receptacle, and described seal receptacle and/or deadweight valve plug are made up of magnetic material, and seal receptacle is attracting with deadweight valve plug magnetic.
As preferred version of the present utility model, the outside face of described deadweight valve plug scribbles rubber layer, and seal receptacle is provided with seal ring.Described rubber layer and seal ring can increase sealing effectiveness.
As preferred version of the present utility model, the transport pipe position corresponding with glissile segment is formed heaves district.The interior diameter heaving district is greater than the interior diameter at other position of transport pipe.Described setting of heaving district, can increase the gap between deadweight valve plug and oil outlet pipe inwall, reduces refueling time.
As preferred version of the present utility model, described deadweight valve plug is pyramid type, and the diameter of deadweight valve plug increases from top to bottom gradually.Cylindrical-conical deadweight valve plug, upper end diameter is less, plug movement of conveniently conducting oneself with dignity, and lower end diameter becomes large, coordinates, prevent the oil droplet in rifle body from falling with seal receptacle.
Compared with prior art, have following beneficial effect is the utility model:
Above-mentioned a kind of nozzle gun barrel with oil drip-preventing structure, is provided with seal receptacle and deadweight valve plug, and when refueling, deadweight valve plug is opened.When oiling is complete, deadweight valve plug, because of deadweight deflection seal receptacle, because of magnetic action adhesive sealing, forms check valve structure, can prevent from next time from extracting oil product when nozzle refuels and drip on the ground.There is the advantages such as oil loss is low, low in the pollution of the environment, performance safety is reliable.

1 oil outlet pipe; 2 self-styled tracheaes; 3 heave district; 4 deadweight valve plugs; 5 seal receptacles; 6 glissile segments.
Detailed description of the invention
Below in conjunction with Fig. 1 and Fig. 2, the utility model is described in detail.
A kind of nozzle gun barrel with oil drip-preventing structure, comprise oil outlet pipe 1, the oil outlet of oil outlet pipe 1 is upper end, self-styled tracheae 2 is provided with in oil outlet pipe 1, there is glissile segment 6 at the middle part of described self-styled tracheae 2, and glissile segment 6 is connected with deadweight valve plug 4, and deadweight valve plug 4 can slide up and down on glissile segment 6, described deadweight valve plug 4 is in pyramid type, and the diameter of deadweight valve plug 4 increases from top to bottom gradually.Oil outlet pipe 1 place of deadweight valve plug 4 bottom is provided with seal receptacle 5, and described seal receptacle 5 and/or deadweight valve plug 4 are made up of magnetic material, and seal receptacle 5 is attracting with deadweight valve plug 4 magnetic.The outside face of described deadweight valve plug 4 scribbles rubber layer, and seal receptacle 5 is provided with seal ring.Described rubber layer and seal ring can increase sealing effectiveness.
As preferred version of the present utility model, the transport pipe position corresponding with glissile segment 6 is formed heaves district 3.The interior diameter heaving district 3 is greater than the interior diameter at other position of transport pipe.Described setting of heaving district 3, can increase the gap between deadweight valve plug 4 and oil outlet pipe 1 inwall, reduces refueling time.
Above-mentioned a kind of nozzle gun barrel with oil drip-preventing structure, be provided with seal receptacle 5 and deadweight valve plug 4, when refueling, the valve opening of nozzle, oil product promotes valve plug 4 of conducting oneself with dignity under pressure, and oil product passes through from the space between deadweight valve plug 4 and oil outlet pipe 1 inwall.When oiling is complete, during the valve closing of nozzle, lift oil gun, upward, deadweight valve plug 4 is partial to seal receptacle 5 because conducting oneself with dignity to transport pipe, because of magnetic action adhesive sealing, form check valve structure, cut off the oil product flow pass in transport pipe, prevent from next time from extracting oil product when nozzle refuels and drip on the ground.There is the advantages such as oil loss is low, low in the pollution of the environment, performance safety is reliable.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
