Abstract
The invention discloses a vacuum gun stripping mechanism driven by pressure. A pressure drive mechanism is composed of a seal cover and an oil pressure drive piston where V-type rings are installed. The vacuum gun stripping mechanism is composed of an upper spring seat, an oil pressure reset spring, a vacuum reset spring, a diaphragm, an engaging pin base, engaging pins, a linkage screw, a linkage threaded rod, a lower spring seat and a vacuum chamber lower cover. The gun stripping mechanism is novel in structure and simple in principle, the double-spring structure and the diaphragm provided with wrinkles on the surface are adopted for guaranteeing stability of the vacuum self-sealing gun stripping function, and the functions of an oil gun are effectively expanded, so that the requirement for self-service refueling is met.
Description
Technical field
The present invention relates to a kind ofly for oil gas, reclaim field, inner integrated oil gas reclaims the self-sealing refueling gun of path, and particularly pressure-actuated vacuum is jumped gunlock structure.
Background technology
Most of common self-sealing refueling gun, adopts three steel balls to jump gunlock structure in conjunction with the vacuum of diaphragm at present, although can meet the jumping rifle demand of nozzle after filling it up with oil, ubiquity jumping rifle function realizes unstable, insecure shortcoming.Appearance along with this Novel oiling mode of self-service refueling machine, not only require nozzle when 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 when self-service refueling in the situation that fuel charger is not worked, oil gun is improper fuel-displaced, causes the generation of the safety misadventures such as the waste of oil resources and fire.
Summary of the invention
For above-mentioned situation, the object of this invention is to provide a kind of needs in situation that system has oil pressure, 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, by capping, the oil pressure actuated plug decomposition pressure driver train of V-type circle is housed, by upper spring seat, oil pressure retracing spring, vacuum retracing spring, diaphragm, engagement key seat, engaging pin, joint bolt, screw connection, lower spring cup, vacuum chamber lower cover, form vacuum and jump gunlock structure.
Described membrane surface has fold.
Described capping inside is provided with copper sheathing.
Jumping gunlock structure of the present invention, 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.Expanded 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 invention.
The specific embodiment
As shown in Figure 1, the present invention 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.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, form vacuum and jump gunlock structure.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 band dynamic diaphragms 7 down move, thereby two engaging pins 9 that make to mesh 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.When filling it up with oil, because diaphragm 7 tops produce vacuum, the effect of pressure reduction, makes upwards distortion of 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, engaging pin 9 engage position no longer now, pushing mechanism in nozzle cannot be worked, while also having realized without oil pressure, the function that nozzle cannot be fuel-displaced, has met the demand of self-service fuel charger.
