Description
Technical field
The utility model relates to oil gas and reclaims nozzle, relates in particular to the reverse nozzle of opening of a kind of direct current and main valve.
Background technology
At present, the petrol service stations in a lot of areas of China be all that oil gas reclaims petrol service station, can realize oil gas that oil gas reclaims and reclaim rifle and used in a large number; But at present oil gas on the market reclaims rifle, oil circuit arrange and main valve open mode on, be mainly two kinds of structures.The first, main valve is opened with respect to oil pressure direction is reverse, and oil circuit square is arranged, and the advantage of this frame mode is that oil gun is difficult for producing pressurization leakage of oil, and its shortcoming is that the flow of oiling is not high because oil circuit resistance is large, the efficiency that impact is refueled.The second, main valve is forward opened with respect to oil pressure direction, and oil circuit linear is arranged, and the advantage of this frame mode is that oil circuit resistance is little, the flow refueling is large, and the efficiency of refueling is high, and its shortcoming is, in the time that fuel charger pressurizes, its impulsive force can be washed main valve open, the phenomenon of the leakage of oil of must pressurizeing; And gasoline is highly volatile fuel, oil gas is inflammable and explosive, and therefore, from security standpoint, the second frame mode exists certain hidden danger.How both having improved the flow refueling, and also avoided pressurization to leak oil condition simultaneously and occurred, is just to make great efforts in the industry the focal spot techniques problem that innovation overcomes at present.
Utility model content
The purpose of this utility model is to provide a kind of direct current and the reverse nozzle of opening of main valve, and it has advantages of, and the flow of oiling is large, good airproof performance and safe and practical.
The utility model is achieved like this, it comprises rifle body and is positioned at gun breech end and the muzzle end at rifle body two ends, it is characterized in that, it also comprises the main spool spring that is positioned at rifle body, secondary main valve, one-level main valve, siphon valve, spool and swing arm, and be positioned at rifle trigger external and that be connected with swing arm one end, the other end of swing arm and spool are near an end in contact of muzzle end, the other end of spool is successively through being stuck on an end face of secondary main valve after siphon valve and one-level main valve, the peripheral ring of secondary main valve is wound with main spool spring, described main spool spring can apply the pressure near one-level main valve direction to secondary main valve.
Preferred structure is: the end face that described secondary main valve is close to one-level main valve is provided with sealing plain cushion.In the outer peripheral sidewall of described one-level main valve, be also provided with sealing plain cushion.
One end that described spool is connected with secondary main valve and one-level main valve is hierarchic structure, and secondary main valve and one-level main valve lay respectively on two adjacent ladders.The end face center that described secondary main valve is close to one-level main valve is provided with the groove for connecting spool end.
Described siphon valve, one-level main valve and secondary main valve are coaxially arranged successively; For structure is compacter, siphon valve, one-level main valve, secondary main valve and gun breech end can also be coaxially set,
The beneficial effects of the utility model are: the utlity model has compact conformation, advantage easy to use, it can be in increasing the flow of nozzle, having avoided pressurization to leak the generation of oil condition, have improved safety; And owing to adopting the reverse structure of main valve, ensure that nozzle, in the time of non-refuelling, has better leak tightness, stop the phenomenon of leakage of oil of pressurizeing, thereby further improved the safe reliability of oil gun.
Brief description of the drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the structural representation of oil gun opening in embodiment of the utility model.
Rifle body 2, gun breech end 3, muzzle end 4, trigger 5, sealing plain cushion 6, main spool spring 7, secondary main valve 8, one-level main valve 9, siphon valve 10, spool 11, swing arm in the drawings, 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
As shown in Figure 1, the utility model is achieved like this, it comprises rifle body 1 and is positioned at gun breech end 2 and the muzzle end 3 at rifle body 1 two ends, its structure is that it also comprises the main spool spring 6 that is positioned at rifle body 1, secondary main valve 7, one-level main valve 8, siphon valve 9, spool 10 and swing arm 11, and be positioned at outside rifle body 1 and the trigger 4 being connected with swing arm 11 one end, the other end of swing arm 11 and spool 10 are near an end in contact of muzzle end 3, the other end of spool 10 is successively through being stuck on an end face of secondary main valve 7 after siphon valve 9 and one-level main valve 8, the peripheral ring of secondary main valve 7 is wound with main spool spring 6, described main spool spring 6 can apply the pressure near one-level main valve 8 directions to secondary main valve 7.
In order to increase the leak tightness of secondary main valve 7 and one-level main valve 8, be close at secondary main valve 7 and on an end face of one-level main valve 8, be provided with sealing plain cushion 5.In the outer peripheral sidewall of described one-level main valve 8, be also provided with sealing plain cushion 5.
One end that described spool 10 is connected with secondary main valve 7 and one-level main valve 8 is hierarchic structure, and secondary main valve 7 and one-level main valve 8 lay respectively on two adjacent ladders.The end face center that described secondary main valve 7 is close to one-level main valve 8 is provided with the groove for connecting spool 10 ends.Also coaxially be provided with siphon valve 9, one-level main valve 8, secondary main valve 7 and gun breech end 2.
In the time that oil gun is closed, spool 10 is not subject to the external force from swing arm 11, now, due to the effect of main spool spring 6, secondary main valve 7 and one-level main valve 8 is fitted tightly, and sealing plain cushion 5 between secondary main valve 7 and one-level main valve 8 makes sealing effectiveness better;
As shown in Figure 2, when oil gun is opened, on trigger 4, carry, drive swing arm 11 to swing, first swing arm 11, to heading on the reverse direction displacement of spool 10 towards oil stream, is then backed down secondary main valve 7, then is backed down one-level main valve 8, thereby make oily stream pass through main valve.And then wash siphon valve 9 open, make oily stream flow to muzzle end 3.In the time that main valve is closed, main spool spring 6 is pressing secondary main valve 7 to be close to one-level main valve 8, and the sealing plain cushion 5 on this two-stage main valve is out of shape, and realize sealing, and spring pressure direction is consistent with oil pressure direction, and the larger sealing effectiveness of oil pressure is better.
