Abstract
The invention discloses a turnover valve of an automobile oil tank. The turnover valve comprises a valve element, a valve body and a valve deck. The valve deck is arranged at the upper end of the valve element and provided with an air hole. An air inlet is formed in the upper end of the valve body, and an air outlet is formed in the lower end of the valve body. The valve element is arranged in the valve body in a vertically moving manner. An elastic device is arranged between the bottom of the valve element and the bottom of the valve body. The turnover valve is characterized in that the valve element comprises an inner core and an outer shell; a boss is arranged at the upper end of the valve element; a glass sheet is arranged at the upper end of the boss; the outer shell coats the periphery of the inner core and is matched with the inner core; a glass sheet guide structure is arranged at the upper end of the outer shell; and the glass sheet is limited in the guide structure in a vertically moving manner and is in sealing fit with the air inlet of the valve body when the oil tank turns over. The turnover valve is simple in design, good in sealing performance and high in production percent of pass, and good benefits can be brought to enterprises.
Description
Technical field
The present invention relates to the improvement invention of a kind of auto parts and components, particularly relate to the improvement invention of a kind of automotive oil tank turning-over valve.
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 exchange pipeline on fuel tank top cover, and automotive oil tank turning-over valve is provided in the inside and outside gas exchange pipeline inside fuel oil pump assembly top cover, fuel oil in preventing from causing fuel tank because of automobile bumpiness or overturning is excessive in gas exchange pipeline, yet with in prior art, turning-over valve internal seal structure Design and Machining technological requirement is too high, domestic making difficulty, it is difficult to meet market demand.
Summary of the invention
The technical problem to be solved is to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, the automotive oil tank turning-over valve of good airproof performance.
In order to solve above-mentioned technical problem, the present invention adopts the following technical scheme that and realizes: this kind of automotive oil tank turning-over valve, include spool, valve body and valve gap, 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, valve body lower end is provided with gas outlet, described spool can move up and down and be arranged in valve body, and bottom spool and between body base, it is provided with elastic device, it is characterized in that: described spool comprises core and shell, described spool upper end is provided with boss, boss upper end is provided with sheet glass, 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 coordinate with the sealing of valve body air inlet when fuel tank overturning.
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, and butyronitrile O RunddichtringO coordinates with blind flange air inlet pipe inner wall sealing.
Described sheet glass is acrylic lucite sheet.
The invention has the beneficial effects as follows the automotive oil tank turning-over valve after improvement, 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 coordinate with the sealing of valve body air inlet, and in processing technology, the flatness of acrylic lucite sheet is easily controlled, it is possible to is formed with valve body air inlet and closely cooperates.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in further detail.
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structure sectional view of the present invention.
Fig. 3 is the installation site figure of the present invention.
Detailed description of the invention
Accompanying drawing illustrates the structure of the present invention, further illustrates it about details in conjunction with accompanying drawing below.nullThis automotive oil tank turning-over valve，Include spool 2、Valve body 1 and valve gap 3，Described valve gap 3 lid is located at valve body 1 upper end，And valve gap 3 is provided with pore 4，Described valve body 1 upper end is provided with air inlet 5，Valve body 1 lower end is provided with gas outlet 6，Described spool 2 can move up and down and be arranged in valve body 1，And it is provided with elastic device 7 between bottom spool 2 and bottom valve body 1，This elastic device 7 is spring，Described spool 2 comprises core 8 and shell 9，Described spool 2 upper end is provided with boss 10，Boss 10 upper end is provided with sheet glass 11，The acrylic lucite sheet 11 that sheet glass 11 is preferably circular，It is matched that described shell 9 is coated on core 8 periphery，And shell 9 upper end is provided with sheet glass 11 correcting structure 12，Described sheet glass 11 can move up and down and be limited in correcting structure 12，And avoided sheet glass 11 to overturn by correcting structure 12 constraint，Sheet glass 11 moves towards valve body 1 air inlet 5 when fuel tank overturning and seals with valve body 1 air inlet 5 and coordinates，Wherein valve body 1 air inlet 5 end face has certain sealing flatness and fineness，Sheet glass 11 can be coordinated to seal.Described correcting structure 12 is to be arranged on the back-up ring 13 above shell 9, and connect some vertical rods 14 of back-up ring 13 and shell 9 upper end, sheet glass 11 is surrounded, form cage shape, four of the preferred spaced set of vertical rod 14, and be close with sheet glass 11, prevent sheet glass 11 from overturning, the most do not hinder the movement of sheet glass 11.Described valve body 1 outer wall top is provided with cannelure, is provided with butyronitrile O RunddichtringO 15 in cannelure, and butyronitrile O RunddichtringO 15 coordinates with blind flange 16 air inlet pipe inner wall sealing.
The present invention, adds a butyronitrile O outside automobile turning-over valve valve body 1, i.e. reduce processing technique difficulty, improves again the sealing in blind flange 16 hole；The air inlet 5 of overflow valve valve body 1, uses acrylic lucite sheet 11 to seal structure, and energy of short duration sealing during automobile overturning stops the function that fuel oil leaks.The present invention designs simply, produces qualification rate high, can bring good benefit to enterprise.
In sum, these are only presently preferred embodiments of the present invention, be not intended to limit protection scope of the present invention.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
