The utility model has the characteristics of can in time discharge the air in the fuel pump assembly to reach the quick start.
Description
Technical field
The utility model is related to a kind of internal combustion engine power plant, more particularly to a kind of T-shaped quick startup motorcycle externally-built is total
Into exhaust apparatus.
Background technology
Fuel oil pump assembly is that vapour rubs the technical term of accessory industry, be electric jet vehicle fuel injection system composition substantially it
One.It is arranged at the fuel oil pump assembly of current motorcycle in fuel tank more, the fuel oil in fuel tank is transported in engine.Effect is
Fuel oil is suctioned out from fuel tank, pressurize after be transported in fuel feed pump.
Fuel oil pump assembly is typically assemblied in below motorcycle tank, engine back upper place, and playing can quickly start vehicle
Effect.Before ignition, fuel oil pump assembly is connected and closed respectively with fuel tank and engine, and it is total to enter into fuel pump in fuel oil
Cheng Qian, fuel oil pump assembly has air, and the atomizer of fuel-displaced pipe end is closed, and assembly inner air cannot
Outer row so that fuel oil can not be completely filled with assembly drain pan, fuel pump suction air, causes difficulty in starting when causing ignition trigger.
Utility model content
For problem above, the utility model devises a kind of T-shaped quick startup motorcycle externally-built assembly exhaust apparatus, with
Solve the problems, such as to cause difficulty in starting because there is air in existing fuel oil pump assembly.
The technical solution of the utility model is：It is vent closure that the exhaust apparatus includes setting gradually, check valve, unidirectional
Valve spring and seal pipe, one-way valve spring lower end is socketed in seal pipe, upper end supporting role in check valve, when check valve is pressurized
Above-mentioned seal pipe is blocked downwards, and exhaust apparatus lower end is additionally provided with oil return pipe.
Preferably, being provided with metal plug on the path located up and down of exhaust apparatus, pass through on the end face of metal plug outside
Epoxide-resin glue water-stop, epoxy resin glue can effective protection plug aoxidize during Long-Time Service, corrode, while ring
Oxygen resin glue has the advantages that water-fast, oil resistant, resistance to quick-fried Sai, even if plug seal failure, epoxide-resin glue can also play sealing effect
Really, assembly application risk is reduced.
Preferably, check valve is hemisphere structure, check valve upper surface is provided with air discharge duct.
Preferably, air discharge duct is 4, in cross structure shape.
Preferably, oil return pipe forms path with flowline.
The beneficial effects of the utility model are：The utility model is mounted with exhaust apparatus, exhaust dress on fuel oil pump assembly
Put upper end to connect with flowline, lower end is connected by oil return pipe with fuel tank.Before not working, check valve is by one-way valve spring
Top, exhaust apparatus forms path with oil return pipe, and the air discharge duct on check valve is used to be vented, even if oil outlet end atomizer is closed
, assembly inner air is compressed by liquid level of fuel oil in fuel tank, then by check valve, through oil return pipe, final assembly inside of discharging enters
To in fuel tank, and then fuel oil can fill up assembly, and total performance can quickly start during igniting.
Description of the drawings
Fig. 1 is the utility model assembly and the partial sectional view at exhaust apparatus.
Fig. 2 is the sectional view of the utility model exhaust apparatus.
Fig. 3 is the structural representation of the utility model check valve.
In figure：1 flowline, 2 exhaust apparatus, 3 oil return pipes, 4 oil inlet pipes, 5 metal plugs, 6 vent closures, 7 check valves,
8 one-way valve springs, 9 seal pipes, 10 air discharge ducts.
Specific embodiment
With reference to the accompanying drawings and examples the utility model is described in further detail.
As Figure 1-3, the exhaust apparatus 2 includes vent closure 6, check valve 7, the one-way valve spring 8 for setting gradually
With seal pipe 9, vent closure 6 plays sealing function, prevents fluid from penetrating from the sealing of upper lid and bottom shell, check valve
The lower end of spring 8 is socketed in seal pipe 9, and upper end supporting role blocks downwards above-mentioned sealing in check valve 7, when check valve 7 is pressurized
Pipe 9, the lower end of exhaust apparatus 2 is additionally provided with oil return pipe 3, and oil return pipe 3 forms path with flowline 1.
In embodiment, metal plug 5 is provided with the path that exhaust apparatus is located about 2, is led on the outside end face of metal plug 5
Cross epoxide-resin glue water-stop, epoxy resin glue can effective protection plug aoxidize during Long-Time Service, corrode, while
Epoxide-resin glue has the advantages that water-fast, oil resistant, resistance to quick-fried Sai, even if plug seal failure, epoxide-resin glue can also play sealing
Effect, reduces assembly application risk.
In embodiment, check valve 7 is hemisphere structure, and the upper surface of check valve 7 is provided with air discharge duct 10, and air discharge duct 10 is 4
Bar, in cross structure shape.
Operation principle of the present utility model is：Before not working, check valve 7 is up pushed up by one-way valve spring 8, exhaust apparatus
2 form path with oil return pipe 3；And assembly inner air is compressed by liquid level of fuel oil in fuel tank, then by check valve 7, through oil return pipe
3, final discharge is entered in fuel tank inside assembly, and fuel oil can fill up assembly, and total performance of now lighting a fire can quickly start.Work as assembly
After startup, fuel pump starts fuel oil to be sucked from oil inlet pipe 4 and is sprayed from flowline 1, at this moment has part oil to enter from flowline 1
Enter in exhaust apparatus 2, check valve 7 is pressed to seal pipe 9 by the pressure effect of fuel oil, and the clogging oil return pipe 3 of check valve 7 makes
Obtain fuel oil to be back in fuel tank without going past oil return pipe 3.
The above is only preferred embodiment of the present utility model, for those skilled in the art come
Say, on the premise of without departing from the utility model principle, some improvement can also be made, it is new that these improvement also should be regarded as this practicality
The protection domain of type.
