Abstract
The utility model discloses a pressure-driven vacuum gun jumping mechanism. The pressure-driven vacuum gun jumping mechanism comprises a pressure driving mechanism and a vacuum gun jumping mechanism body, wherein the pressure driving mechanism is composed of a close cover and an oil pressure driving plug provided with a V-type ring, and the vacuum gun jumping mechanism is composed of an upper spring base, an oil pressure reset spring, a vacuum reset spring, a diaphragm, a meshed pin base, a meshed pin, a connection screw, a connection screw rod, a lower spring base and a lower vacuum chamber cover. The pressure-driven vacuum gun jumping mechanism is novel in structure and simple in principle. Due to the facts that the two-spring structure is adopted, and the surface of the diaphragm is provided with wrinkles, the stability of the vacuum self-closed gun jumping function is ensured; the functions of a fuel gun are effectively expanded, and the requirement for self-service fueling is met.
Description
Technical field
The utility model relates to a kind of for oil gas recovery field, the self-sealing refueling gun of inner integrated oil gas recovery path, and particularly pressure-actuated vacuum is jumped gunlock structure.
Background technology
Most of common self-sealing refueling gun at present, adopts three steel balls to jump gunlock structure in conjunction with the vacuum of diaphragm, although can meet nozzle in the jumping rifle demand of filling it up with after oil, ubiquity jumping rifle function realizes unstable, insecure shortcoming.Along with the appearance of this Novel oiling mode of self-service refueling machine, not only require nozzle in the time filling it up with oil, can realize self-styled jumping rifle, and require in system without oil pressure in the situation that, oil gun can not be opened fuel-displaced, avoid occurring oil gun in the time of self-service refueling in the situation that fuel charger is not worked, oil gun is improper fuel-displaced, causes the generation of the safety misadventure such as waste and fire of oil resources.
Summary of the invention
For above-mentioned situation, the purpose of this utility model is to provide a kind of needs in situation that system has oil pressure, and the vacuum that nozzle just can be opened is jumped gunlock structure, not only can realize the common self-styled jumping rifle function of nozzle, can also meet the requirement of self-service refueling machine, specifically adopt following technical scheme:
A kind of pressure-actuated vacuum is jumped gunlock structure, the oil pressure actuated plug that v shaped ring is housed can be in capping under the oil pressure effect of top up-and-down movement, vacuum chamber lower cover and closure position are fixed, oil pressure retracing spring is installed between upper spring seat and vacuum chamber lower cover, vacuum retracing spring is installed between upper spring seat and lower spring cup, diaphragm is fixed on and is engaged between key seat and lower spring cup with screw connection by joint bolt, the edge of diaphragm is fixed by the compacting of vacuum chamber lower cover, can relative motion between screw connection and upper spring seat, engaging pin is installed in the groove of engagement key seat.
Described membrane surface has fold.
Described capping inside is provided with copper sheathing.
Jumping gunlock structure of the present utility model, novel structure, principle is simple, adopts double-spring structure, and surface is with the diaphragm of fold, has all guaranteed the stability of the self-styled jumping rifle of vacuum function.Expand the function of nozzle, made it meet the requirement of self-service oiling.
Accompanying drawing explanation
Accompanying drawing 1 is integral structure cutaway view of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model by capping 1, the oil pressure actuated plug 2 decomposition pressure driver trains of V-type circle 4 are housed, in capping 1, be provided with copper sheathing 14.Form vacuum and jump gunlock structure by upper spring seat 3, oil pressure retracing spring 5, vacuum retracing spring 6, diaphragm 7, engagement key seat 8, engaging pin 9, joint bolt 10, screw connection 11, lower spring cup 12, vacuum chamber lower cover 13.Between upper spring seat 3 and lower spring cup 12, be provided with vacuum retracing spring 6, between upper spring seat 3 and vacuum chamber lower cover 13, be provided with oil pressure retracing spring 5.When system is in the situation that having oil pressure, pressure oil enters from two apertures on capping 1 top, promote the down motion in copper sheathing 14 of oil pressure actuated plug 2, compression oil pressure retracing spring 5 and vacuum retracing spring 6, under the effect of vacuum retracing spring power, lower spring cup 12 is with dynamic diaphragm 7 down to move, thereby two engaging pins 9 that make to engage on key seat 8 down move to engage position, under the effect of oil gun pushing mechanism, now oil gun can be opened, and carries out refueling operation.In the time filling it up with oil, because diaphragm 7 tops produce vacuum, the effect of pressure reduction, is upwards out of shape diaphragm 7, will on engagement key seat 8, lift, and engaging pin 9 disengaged positions, realize the self-styled jumping rifle of vacuum.There is fold on the surface of diaphragm 7, can effectively increase the area of diaphragm 7, strengthens while producing vacuum, and the upper lifting force of diaphragm, improves the reliability of jumping rifle.And when system is during without oil pressure, upper spring seat 3 is under the effect of oil pressure retracing spring 5, all the time be in position as shown in the figure, now no longer engage position of engaging pin 9, pushing mechanism in nozzle cannot be worked, also, while having realized without oil pressure, the function that nozzle cannot be fuel-displaced, has met the demand of self-service fuel charger.
