Description
Technical field
This utility model relates to a kind of fuel charger Pull breaking ualve, is specifically related to a kind of breaking for emergency cut-off
Valve.
Background technology
Pull breaking ualve is a kind of ejection escape shearing device connecting nozzle and fuel charger.If refueling machine oil
It is not provided with Pull breaking ualve between pipe and nozzle, after adding oil to automobile, have forgotten nozzle from automobile
Fuel tank in extract, may result in automobile after start and fuel charger forgotten about it, or oil filling pipe is broken make combustion
Oil leaks and causes the generation of accident.And after Pull breaking ualve is set, if nozzle is by exceeding the power of default pulling force
Pull then its meeting to disconnect at Pull breaking ualve timely, and after disconnection, Pull breaking ualve can close oil pipe, thus
Avoid the destruction to fuel charger, do not have fuel leakage and the blast being likely to occur thereof, it is ensured that the person
Safety.
Although existing Pull breaking ualve can meet fracture in time to a certain extent, ensure the demand of safety, but
Be its actually used during remain certain problem, be in particular in: 1, internal structure is complicated,
Pull-off force is unstable, and reliability is the highest, need not disconnect when, false triggering occurs, the most disconnected at needs
Can not trigger timely again when of opening；2, part-structure is disposable connection, not reproducible use after breaking.
Utility model content
It is stable that the technical problems to be solved in the utility model is to provide a kind of pull-off force, seals reliable, and repeats
The Pull breaking ualve used.
Realizing the technical solution of the utility model and include sebific duct end valve body 1, oil gun end valve body 7, both are by peace
The C-shaped back-up ring 12 being contained in oil gun end valve body draw-in groove blocks the groove of sebific duct end valve body 1 and links into an integrated entity,
Equipped with H-shaped circle 9 in the middle of oil gun end valve body, it is respectively provided with sealing ring A 8, sealing ring B on H-shaped circle 9 both sides
10, to prevent the generation of external leakage.Sebific duct end valve body 1 is equipped with profile of tooth circle 13, inside sebific duct end valve body 1
Sealing equipped with oil circuit Packing spring 4 between slide block 5 equipped with spring base 3, spring base 3 and oil circuit, oil circuit seals
Equipped with sealing ring C 11 on slide block 4, internal equipped with gas circuit connection shaft 6, gas circuit connection shaft at oil gun end valve body 7
6 one end are contained in oil circuit and seal in slide block 5, and oil circuit Packing spring 4 is in compressive state.Break so that whole
Valve is on internal axis direction, and each part mutually holds, and can be prevented effectively from Oil shocking.
This utility model can be when oil gun be by certain pulling force, and sebific duct end valve body takes off automatically with oil gun end valve body
Open, oil inlet end valve inner seal spool, thus effectively protection fuel charger and vehicle are without prejudice, and prevent oil
Material leaks.And its pull-off force is stable, lightweight, structure is reliable, reusable.Simultaneously because drawing
Disconnected valve is internally provided with shock absorbing ring and damped ring, therefore makes whole Pull breaking ualve compact conformation, and not by oil pressure ripple
Move and its life-span of external force vibration influence and flow.
Accompanying drawing explanation
Accompanying drawing 1 is total assembling structure sectional view of the present utility model.
In figure: 1-sebific duct end valve body, 2-overcoat, 3-spring base, 4-oil circuit Packing spring, 5-oil circuit
Seal slide block, 6-gas circuit connection shaft, 7-oil gun end valve body, 8-sealing ring A, 9-H shape
Circle, 10-sealing ring B, 11-sealing ring C, 12-C shape back-up ring, 13-profile of tooth circle.
Detailed description of the invention
Pull breaking ualve as shown in Figure 1, including sebific duct end valve body 1, oil gun end valve body 7, both are by being arranged on
C-shaped back-up ring 12 in oil gun end valve body 7 draw-in groove blocks the groove of sebific duct end valve body 1 and links into an integrated entity, oil
Equipped with H-shaped circle 9 in the middle of rifle end valve body 7, it is respectively provided with sealing ring A 8, sealing ring B on H-shaped circle 9 both sides
10, to prevent the generation of external leakage.Sebific duct end valve body 1 is equipped with profile of tooth circle 13, inside sebific duct end valve body 1
Sealing equipped with oil circuit Packing spring 4 between slide block 5 equipped with spring base 3, spring base 3 and oil circuit, oil circuit seals
Equipped with sealing ring C 11 on slide block 5, internal equipped with gas circuit connection shaft 6, gas circuit connection shaft at oil gun end valve body 7
6 one end are contained in oil circuit and seal in slide block 5, and oil circuit Packing spring 4 is in compressive state.Break so that whole
Valve is on internal axis direction, and each part mutually holds, and can be prevented effectively from Oil shocking.Last outside valve body
Overcoat 2 in surface cover, to shield.
This utility model is when normally working, and the joint of oil gas recovery rubber tube is connected to the sebific duct end valve of Pull breaking ualve
Body 1, the oil gun end valve body 7 of Pull breaking ualve is connected to nozzle, the fluid of oil gun end valve body 7 output and nozzle
The oil gas runner reclaimed is mutually isolated, does not gangs up.H-shaped circle 9 and profile of tooth circle 13 it is provided with between two valve bodies,
H-shaped circle 9 makes its compact conformation, slows down the vibrations of suffered external force, and profile of tooth circle 13 can prevent spirit between two parts
Live and rotate, affect sealing ring A 8, the service life of sealing ring B 10.Its pull-off force is by C-shaped back-up ring 12
Being arranged on the groove shapes of sebific duct end valve body 1 to ensure the accuracy of pull-off force, pull-off force is positively retained at 1000
About cattle, it is possible to adjust different pull-off forces as desired by changing shape, and can reuse,
Reduce cost.
When nozzle is pullled by the external force of about 1000 Ns, C-shaped back-up ring 12 will be from sebific duct end valve body
Slipping in the groove of 1, so that two parts disengage automatically, in sebific duct end valve body 1, oil circuit seals slide block 5 at oil
Under the effect of road Packing spring 4, slide the most rapidly, seal valve port, be contained in oil circuit and seal on slide block 5
Sealing ring C 11 can make sealing tighter, effectively prevents the oil plant in sebific duct from leaking.The one of gas circuit connection shaft 6
End and oil circuit in sebific duct end valve body seal slide block 5 close-fitting, the other end and nozzle close-fitting.
