Air valve temporary close will increase tank internal pressure, cause if Liquid level air bleeding valve cannot open exhaust in time at this time
There are the risks of dilatancy for fuel tank.Exhaust can be opened in time after it requires Liquid level air bleeding valve Temporarily Closed, tieed up
The pressure that fuel tank normal work needs is held, this performance of valve is known as reopening performance.Liquid level air bleeding valve is good
Reopening performance contributes to automobile to keep the pressure balance of fuel tank inside and outside under harsh operating mode, prevents from generating inside fuel tank
Excessively high positive pressure either crosses high negative pressure and avoids fuel tank " expansion " or " shriveling ".Traditional Liquid level air bleeding valve is by 8 zero
Part forms, wherein " ontology ", " bearing ", " sealing gasket cover ", " float ", " bottom cover " are plastic article, " gasket 1 " and " gasket
2 " be rubber parts, and " spring " is metalwork, and " sealing gasket cover " is welded on " float ", " gasket for fixing " gasket 2 "
1 " is assemblied on " bearing ", is also assembly relation between remaining accessory.Traditional liquid level control air bleeding valve has the following problems：1) it is real
The structure for now reopening performance is complex, shares " gasket 1 ", " bearing ", " sealing gasket cover ", " gasket 2 ", " float "
Totally five parts composition, cost is higher, 2) traditional Liquid level air bleeding valve dynamic liquid quantity of fuel leakage is more, may go out
The closing in advance of existing valve, float weight flexible design degree be not high；3) deficiency of traditional liquid level control air bleeding valve, is realized " again
Open performance " it is complicated, need assemble welding；4) prevent liquid fuel leakage structure single.Therefore, urgent need one
The new scheme of kind solves the technical problem.

The course of work：
Referring to Figure 11, in automobile fuel filler or driving process, since fuel oil shakes, liquid fuel pats float, causes
Liquid level air bleeding valve temporary close, at this time if Liquid level air bleeding valve cannot open exhaust in time will make tank internal pressure
Raising, leads to risk of the fuel tank there are dilatancy.It can be opened in time after it requires Liquid level air bleeding valve Temporarily Closed
Exhaust is opened, the pressure that fuel tank normal work is maintained to need.Valve closing schematic diagram is as shown in figure 11,
Although tank internal pressure is bigger after Liquid level exhaust valve closure, due to the venthole among gasket
Aperture it is smaller, so float open under the effect of gravity the first order exhaust.Shown in first order exhaust schematic diagram 12,
The exhaust of the Liquid level air bleeding valve first order discharges a part of pressure of fuel tank, and tank internal pressure is made further to subtract
Small, the weight of float is acted on gasket at this time.The gravity that gasket its own gravity and float are applied to it is more than pressure
The elastic force upward with compressed spring that upwards pressure that difference generates, sealing surface is detached from valve body on gasket, valve opening the
Secondary exhaust.Valve can be with trim tank inside and outside pressure by two-stage exhaust.Second level exhaust schematic diagram is as shown in figure 13, should
The two-stage that Liquid level air bleeding valve designing scheme realizes valve by a gasket structure is opened, and simplifies valve again
Opening structure, at the same present design by gasket and float can trim designs reduce process costs.
The present invention can also combine at least one of embodiment 2,3,4,5 technical characteristics with embodiment 1 to be formed
New embodiment.
It should be noted that above-described embodiment, is not used for limiting protection scope of the present invention, in above-mentioned technical proposal
On the basis of made equivalents or replacement each fall within the range that the claims in the present invention are protected.
