Description
Technical field
This utility model relates to the improvement invention of a kind of auto parts and components, particularly relates to changing of a kind of automotive oil tank turning-over valve
Set out bright.
Background technology
Automotive oil tank is fuel-displaced needs fuel tank inner and outer air pressure to keep balance, so that arrange inside and outside gas on fuel tank top cover
Exchange pipeline, and automotive oil tank turning-over valve is provided in the inside and outside gas exchange pipeline inside fuel oil pump assembly top cover, is used for
Prevent from causing because of automobile bumpiness or overturning the fuel oil in fuel tank excessive in gas exchange pipeline, yet with prior art
In, turning-over valve internal seal structure Design and Machining technological requirement is too high, domestic making difficulty, it is difficult to meet market demand.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, close
The automotive oil tank turning-over valve that envelope property is good.
In order to solve above-mentioned technical problem, this utility model adopts the following technical scheme that and realizes: this kind of automobile oil
Case turning-over valve, includes spool, valve body and valve gap, and described valve gap is arranged on spool upper end, and valve gap is provided with pore, described valve
Body upper end is provided with air inlet, and valve body lower end is provided with gas outlet, and described spool can move up and down and be arranged in valve body, and bottom spool
And it is provided with elastic device between body base, it is characterised in that: described spool comprises core and shell, and described spool upper end is provided with
Boss, boss upper end is provided with sheet glass, and it is matched that described shell is coated on core periphery, and shell upper end is provided with sheet glass
Correcting structure, described sheet glass can move up and down and be limited in correcting structure, and seals with valve body air inlet when fuel tank overturning
Coordinate.
Described correcting structure is to be arranged on the back-up ring above shell, and connects some vertical rods of back-up ring and shell upper end.
Described valve outer wall top is provided with cannelure, is provided with butyronitrile O RunddichtringO in cannelure, butyronitrile O RunddichtringO with
Blind flange air inlet pipe inner wall sealing coordinates.
Described sheet glass is acrylic lucite sheet.
The beneficial effects of the utility model are the automotive oil tank turning-over valves after improving, and the sealing structure outside valve body uses butyronitrile
O RunddichtringO and blind flange air inlet pipe inner wall sealing；Valve inner uses acrylic lucite sheet sealing structure to enter with valve body
QI KOU seals and coordinates, and in processing technology, the flatness of acrylic lucite sheet is easily controlled, it is possible to the valve body air inlet degree of lip-rounding
One-tenth closely cooperates.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structure sectional view of the present utility model.
Fig. 3 is installation site figure of the present utility model.
Detailed description of the invention
Accompanying drawing illustrates structure of the present utility model, further illustrates it about details in conjunction with accompanying drawing below.This automobile
Fuel tank turning-over valve, includes spool 2, valve body 1 and valve gap 3, and described valve gap 3 lid is located at valve body 1 upper end, and valve gap 3 is provided with gas
Hole 4, described valve body 1 upper end is provided with air inlet 5, and valve body 1 lower end is provided with gas outlet 6, and described spool 2 can move up and down and be arranged on valve
In body 1, and bottom spool 2 and bottom valve body 1 between be provided with elastic device 7, this elastic device 7 is spring, and described spool 2 comprises
Core 8 and shell 9, described spool 2 upper end is provided with boss 10, and boss 10 upper end is provided with sheet glass 11, and sheet glass 11 is preferably circle
The acrylic lucite sheet 11 of shape, it is matched that described shell 9 is coated on core 8 periphery, and shell 9 upper end is provided with glass
Sheet 11 correcting structure 12, described sheet glass 11 can move up and down and be limited in correcting structure 12, and kept away by correcting structure 12 constraint
Exempting from sheet glass 11 to overturn, sheet glass 11 moves towards valve body 1 air inlet 5 when fuel tank overturning and seals with valve body 1 air inlet 5 joins
Closing, wherein valve body 1 air inlet 5 end face has certain sealing flatness and fineness, it is possible to coordinate sheet glass 11 to seal.Described
Correcting structure 12 is to be arranged on the back-up ring 13 above shell 9, and connects some vertical rods 14 of back-up ring 13 and shell 9 upper end, will
Sheet glass 11 surrounds, and forms cage shape, four of the preferred spaced set of vertical rod 14, and is close with sheet glass 11, prevents
Sheet glass 11 overturns, and does not the most hinder the movement of sheet glass 11.Described valve body 1 outer wall top is provided with cannelure, is provided with in cannelure
Butyronitrile O RunddichtringO 15, butyronitrile O RunddichtringO 15 coordinates with blind flange 16 air inlet pipe inner wall sealing.
This utility model, adds a butyronitrile O outside automobile turning-over valve valve body 1, i.e. reduce processing technique difficulty, again
Improve the sealing in blind flange 16 hole；The air inlet 5 of overflow valve valve body 1, uses acrylic lucite sheet 11 to seal knot
Structure, energy of short duration sealing during automobile overturning, stop the function that fuel oil leaks.This utility model design is simple, produces qualification rate high, energy
Good benefit is brought to enterprise.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit of the present utility model
Protection domain.All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all should wrap
Within being contained in protection domain of the present utility model.
