Description
Technical field
The utility model relates to a kind of car accessories more particularly to a kind of gasoline engine Tipping valves.
Background technique
Tipping valve is applied in vehicle fuel supply system, the fuel pump flange plate being mounted in vehicle fuel supply system
In, so that fuel tank internal air pressure is maintained at certain value.Under the condition of high temperature, Tipping valve discharges oil vapour when tank internal pressure is excessively high
It is stored into canister, carries out tonifying Qi when tank internal pressure is too low under high-speed running automobile state again, making fuel tank is not in contracting
Flat phenomenon；In addition, being closed inside Tipping valve when accident overturning occurs in automobile, preventing oil tank fuel from leaking outside.
Existing Tipping valve work present situation: 1, air-tightness: being sealed between Tipping valve and ring flange is hard close between plastics
Envelope, 2, fixation: being fixed as retainer ring and installation aperture interference and being hangnail shape between the products such as Tipping valve and ring flange makes to turn over
Vehicle valve is fixed.
Existing Tipping valve can have the following deficiencies: in actual use
(1) influence of air-tightness: being stamped that size and circularity etc. are more demanding on product, oil of the upper cover in long term high temperature
May deform because of stress in steam etc. causes air-tightness bad.
(2) fixed influence: being fixed as interference back-off connection between Tipping valve and ring flange etc., when metal retainer ring by
Power is excessive, may cause upper cover and falls off.
Therefore, there are also the places promoted for the Tipping valve of the prior art.
Utility model content
The purpose of this utility model is to provide a kind of Tipping valves, are asked with solving technology existing for existing automobile Tipping valve
Topic.
In order to achieve the above objectives, the utility model provides a kind of Tipping valve, comprising: upper cover, O-ring, valve block, is consolidated shell
Fixed button, seal rubber piece, spool, spring and bottom cover；Connection type therein are as follows: the upper cover clamping connects the top of the shell
End；The O-ring is arranged the top for connecting the shell；The valve block is placed inside the upper end of the shell；The fixing buckle
Insertion connects the spool after connecting the seal rubber piece, and the spring insertion connects in the spring eye of the spool, described
Bottom cover connects the lower end of the shell for spool and spring retainer in the inside of the shell.
According to Tipping valve described in the utility model preferred embodiment, the outer surface of the shell includes two shell cards
Button, corresponding described two shells, which are buckled on ring flange, is arranged two flanges buckles.
The utility model improves existing Tipping valve, and most important purpose is exactly to make Tipping valve more have reality
The property used.Specific purposes are as described below:
1, it newly designs a practical Tipping valve: the sealing between influence Tipping valve and ring flange is changed to rubber seal,
The production difficulty for reducing the part of product related seals makes up the unstable formation of plastic injection piece sealing shape, size
Slight gap, increased sealing reliability；
2, it newly designs a practical Tipping valve: the fixation of Tipping valve and ring flange being changed to snap connection fixation, increase
Stationarity.
Therefore, compared with prior art, the utility model has the advantage that
One, the application rubber seal will not because shell and flange etc. parts slight deformation due to influence to seal；
Two, the application, which snaps connection, keeps the stationarity of Tipping valve more preferable.
Certainly, any one specific embodiment for implementing the content of the present invention, might not have all of the above simultaneously
Technical effect.
Detailed description of the invention
Fig. 1 is the outside drawing of the utility model Tipping valve；
Fig. 2 is the cutaway view of the utility model Tipping valve；
Fig. 3 is the Structure explosion diagram of the utility model Tipping valve；
Fig. 4 is the exhaust condition figure of the utility model Tipping valve；
Fig. 5 is the suction condition figure of the utility model Tipping valve.
Specific embodiment
Below in conjunction with attached drawing, the utility model is illustrated.
Please refer to Fig. 1, Fig. 2 and Fig. 3, a kind of Tipping valve, comprising: upper cover 1, O-ring 3, valve block 4, is fixed shell 2
Button 5, seal rubber piece 6, spool 7, spring 8 and bottom cover 9；The upper cover 1 connects the top of the shell 2, and the mode of connection is
The upper cover 1 devises card slot and the shell 2 devises card convex, and the upper cover 1 and the shell 2 are connected in a manner of clamping
It connects；The O-ring 3 is arranged the top for connecting the shell 2, and after assembly, the O-ring 3 will not be taken off by the upper cover 1 limit
It falls；The valve block 4 is placed inside the upper end of the shell 2, and the valve block 4 will not be in the shell 2 by the upper cover 1 limit
Portion drops out；The fixing buckle 5 connects the upper outer end of the insertion connection spool 7 after the seal rubber piece 6, the spool 7
After insertion connects the shell 2, the insertion of spring 8 is connected in the spring eye of 7 lower end of spool, then with the bottom cover 9 company
The lower end for connecing the shell 2 limits spool 7 and spring 8 in the inside of the shell 2.
As described above, the outer rim of the O-ring 3 protrudes from the outer rim of upper cover 1 and shell 2, therefore after combining Tipping valve
When installation, Tipping valve is mounted on ring flange, since the installation aperture of the O-ring 3 and ring flange is interference fit, is played close
Envelope effect, is a kind of sealing flexible, will not influence to seal because of the slight deformation of shell 2 and the part of ring flange etc..
As shown, the outer surface of the shell 2 further includes two shell buckles 10, corresponding described two shell buckles
10, two flanges are set on ring flange and buckle (not shown), when installation, described two shells buckles 10 and two flanges buckles
Clamping, the mode of this clamping, which allows Tipping valve to be fixed on ring flange, to fall off, and keep the stationarity of Tipping valve more preferable.
In addition, please also refer to Fig. 4 and Fig. 5, the exhaust condition figure and suction condition figure of Tipping valve, valve block 4 is in exhaust shape
By air-flow to jack-up when state, and in suction condition by air-flow to compacting.
The utility model improves existing Tipping valve, and the sealing between influence Tipping valve and ring flange is changed to rubber
Sealing, reduces the production difficulty of the part of product related seals, makes up the unstable shape of plastic injection piece sealing shape, size
At slight gap, increased sealing reliability；And the fixation of Tipping valve and ring flange is changed to snap connection fixation, increase
Stationarity.
Therefore, compared with prior art, the utility model has the advantage that
One, the application rubber seal will not because shell and flange etc. parts slight deformation due to influence to seal；
Two, the application, which snaps connection, keeps the stationarity of Tipping valve more preferable.
Disclosed above is only several specific embodiments of the utility model, but the utility model is not limited to this, is appointed
What what those skilled in the art can think variation, should all fall within the protection scope of the present utility model.
