Detailed description of the invention
Below in conjunction with the accompanying drawings and the specific embodiments the present invention is described in further detail.
As shown in Figure 1, a kind of oil-gas recovery self-sealing nozzle, comprise rifle body 9, gun barrel 5, main valve 11, vacuum valve assembly 13 and handle 16, described handle 16 is particular polymeric plastic material, a hand gets final product simple engage a gear, lighten one's labor load, increase work efficiency, oil product passage is shaped with in described rifle body 9, described main valve 11 and vacuum valve assembly 13 are arranged in this oil product passage, are also provided with to respond to oil product pressure by pressure sensitive valve assembly 17 and realize oil gun self-styled gear mechanism with no pressure in described oil product passage.When after fuel charger energising, oil product pressure impels the action of described pressure sensitive valve assembly 17, and a light grasping member 16 of have gentle hands can easily be put into gear shooting, and oil product i.e. normal inflow; Under fuel charger closedown, accidental power failure etc. do not have oil product pressure condition, it is self-styled that pressure sensitive valve assembly 17 controls oil gun, prevents unexpected generation.
The inner side of described gun barrel 5 is provided with induction valve 6 and aspirate tube 4, and the end of this aspirate tube 4 is connected with described vacuum valve assembly 13, and described gun barrel 5 sidewall is provided with the sensing hole 7 be connected with above-mentioned induction valve 6.During oiling, extraneous air enters this aspirate tube 4 endlessly, and oil gun normally works; When oil product fills fuel tank contact induction hole 7 moment, vacuum valve assembly 13 is found time residual air and form vacuum instantaneously, and impel gear mechanism to unlock, oil gun is self-styled.
Be provided with position sensor valve module 12 between described aspirate tube 4 and described vacuum valve assembly 13, this orientation Inductance valve assembly 12 is made up of the coniform self-styled chamber in valve pocket, valve pocket front and the steel ball of valve pocket inside.When gun barrel 5 mouthfuls of sensings are greater than horizontal plane position, position sensor valve module 12 action, steel ball enter self-styled chamber block outside air enter vacuum valve assembly 13 so that formed vacuum, oil gun is self-styled.
The oil inlet end of described vacuum valve assembly 13 is provided with Drop-proof valve assembly 14.When fuel charger power-off; oil product pressure reduces instantaneously; pressure sensitive valve assembly 17 action; oil gun is self-styled; oil gun from being honored as a queen, Drop-proof valve assembly 14 two springs actions at once and sealing, oil product is stopped in oil product passage; in short time, namely gun barrel 5 mouthfuls does not have oil droplet to drip, and reaches the object of saving oil product, protection of the environment.
Also return gas channel is shaped with in described rifle body 9, described return gas channel is arranged on above described oil product passage, the termination of described return gas channel and described oil product passage is provided with Oil-gas Separation valve body 10, the petroleum vapor recovery pipe 3 that internal diameter is greater than gun barrel 5 external diameter is set with outside described gun barrel 5, be configured for the petroleum vapor recovery passage reclaiming oil gas between described gun barrel 5 outer wall and petroleum vapor recovery pipe 3 inwall, this petroleum vapor recovery passage is connected with described return gas channel.Gun barrel 5 is set up petroleum vapor recovery pipe 3, and the oil gas produced in automotive oil tank when solving oiling can be dispersed in air, works the mischief, cause environmental pollution and potential safety hazard to the physical and mental health of gas station attendant, the problem of waste mass energy.Proportion adjustment valve module 15 is installed in described return gas channel, gas liquid ratio can be adjusted to 1-1.2:1 by this proportion adjustment valve module 15, to meet country and international standard.
Be set with splash guard 2 outside described petroleum vapor recovery pipe 3, in refueling process, this splash guard 2 is fitted with automobile fuel tank port, prevents oil gas from leaking.
The oil inlet end of described rifle body 9 is provided with rubber hose coupling 8, is linked together with sebific duct by this rubber hose coupling 8.
Petroleum vapor recovery nozzle working medium of the present invention is gasoline, and operation pressure is 0.2MPa, and flow is 50L/min, and gun barrel 5 mouthfuls is not more than 4 ohm to rubber hose coupling 8 resistance.The parts such as vacuum valve assembly 13, pressure sensitive valve assembly 17, position sensor valve module 12, Drop-proof valve assembly 14, petroleum vapor recovery pipe 3 are combined on rifle body 9 by the present invention originally, make oil-gas recovery self-sealing nozzle of the present invention integrate orientation self-styled, respond to self-styled, petroleum vapor recovery, antidrip and one-hand operation etc. are multi-functional, design precision, be skillfully constructed rationally, there is the advantages such as simple to operate, performance safety is reliable, long service life, suitable wide popularization and application.
The above, be only present pre-ferred embodiments, therefore can not limit scope of the invention process with this, and the equivalence namely done according to the present patent application the scope of the claims and description changes and modifies, and all should still remain within the scope of the patent.
