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 oil pipe is connected with oil connector interference fit, and concentric setting of axial line of oil pipe and described oil connector, thoroughly avoid the oil leakage fault occurring in nozzle, improved the safety in utilization of nozzle.Comprise body 1 and 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, the concentric setting of axial line of described oil pipe 2 one end and described oil connector 3, and both adopt interference fit to connect, connect closely, make not have gap between oil connector 3 and oil pipe 2, avoid gasoline from this gap, to enter into the generation that causes oil leakage fault in body 1, guaranteed the safety in utilization of nozzle.Described oil pipe 2 other ends are fixedly connected with described reflux valve 7 by ring seat joint 6.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 is used for cutting off the input from tube sealing 4 interior air from sealing assembly, thereby make to be negative pressure state in oil outlet 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, stretch to reflux valve 7, the other end of the utility model embodiment middle shell 51 is designed to funnel-form, be convenient to ball 53 and block rapidly air extractor duct 54, certainly ball 53 in other embodiment of the present utility model, also 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, after oiling finishes, lift oiling gun barrel, make described layback 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, stop exporting gasoline; Maybe, when there is the unforeseen circumstances that gun barrel comes off from fuel tank, when gun barrel is lifted, ball 53 is slipped to housing 51 air extractor ducts 54 equally, realizes self-styledly, has avoided the generation of the unforeseen circumstancess such as nozzle leakage of oil, has 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 can fuel tank normally fill it up with under oil condition, realize self-styled, also can lift artificially gun barrel utilization layback from sealing assembly 5, realize at any time the self-sealing function of nozzle, be not limited to fill it up with just can be self-styled under oil condition, greatly improved the use alerting ability of nozzle; The more important thing is, the utility model the unexpected situation such as can also 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.
