Description
Technical field
The utility model relates to a kind of valve, in particular to a kind of fuel tank ventilation valve.
Background technique
Fuel tank ventilation valve is mounted on the top of fuel tank assembly, in traditional fuel tank ventilation valve technology, when normal vehicle operation,
Exhaust valve is opened always fuel-steam is discharged, and still, when vehicle topples over or overturns, exhaust valve is automatically closed.Six skill of state
Exhaust valve in art: under normal circumstances, allowing fuel-steam to flow in canister from fuel tank, prevents from generating excessively high positive pressure in fuel tank
Power；In work and oiling, if tank pressure is sufficiently high, head valve is opened, and more fuel-steams is allowed to flow to carbon from fuel tank
In tank；In canister desorption, allows fresh air to add in fuel tank through canister, prevent from generating high negative pressure in fuel tank；It is special
Under feelings are missed, when meeting with overturning or wide-angle tilt, exhaust valve is closed, and prevents fuel leakage.
Utility model content
The purpose of the utility model is to provide a kind of high leakproofness fuel tank Tipping valves to enhance float by increasing air hole
Gas permeability, avoid generating higher pressure in fuel tank.
Purpose of the utility model is realized as follows: a kind of high leakproofness fuel tank Tipping valve, including setting is inside the shell
Valve body, the bottom of shell is provided with carrier base, and valve body is mounted on carrier base, offer exhaust outlet at the top of the valve body,
The exhaust ports are provided with disk, and the float that can be floated up and down is provided in the valve body, and the side of the float offers
Air hole, the gasket of the buoy top setting and closing exhaust outlet, the sealed pad lid of gasket is fixed, described
The bottom of shell is provided with bottom cover, and carrier base is mounted on bottom cover.
Compared with prior art, the beneficial effects of the utility model are, the utility model in float side by opening up
Air hole is vented in time by float internal cavity using air hole, is met in the stabilization of float when so that fuel tank liquid level rising
It rises, so that it is reliable to guarantee that the liquid of valve assembly closes high precision.The utility model can be used in fuel tank of vehicle.
As further limiting for the utility model, the exhaust outlet is machined with incline structure, corresponding valve body
Ramp structure is processed at top, and the sealed pad lid of gasket is mounted on ramp structure.
In order to enhance the leakproofness of valve body and shell, the side of the valve body is provided with annular groove, sets in the annular groove
It is equipped with sealing ring.
In order to further enhance the leakproofness of the utility model, it is machined with protrusion in the middle part of the carrier base, is covered in protrusion
Equipped with spring, the upper end of spring is contradicted inside float.Under normal condition, since the gravity of float is greater than spring force,
Spring is in compressive state, and when toppling over, after the utility model inclination, float is carried on the gravity on spring and is decomposed,
When being less than spring force, float is jacked up and closes exhaust outlet by spring.
Detailed description of the invention
Fig. 1 is the utility model schematic diagram of internal structure.
Fig. 2 is the utility model stereoscopic schematic diagram.
Fig. 3 is Floater Structure schematic diagram in the utility model.
Wherein, 1 shell, 2 valve bodies, 2a exhaust outlet, 3 disks, 4 floats, 4a air hole, 5 carrier bases, 5a protrusion, 6 bottom covers, 7
Spring, 8 sealing gasket covers, 9 gaskets, 10 sealing rings.
Specific embodiment

It is equipped with disk 3, the float 4 that can be floated up and down is provided in valve body 2, the side of float 4 offers air hole 4a, 4 top of float
Gasket 9 with closing exhaust outlet 2a is set, and the sealed pad lid 8 of gasket 9 is fixed, and the bottom of shell 1 is provided with bottom cover
6,5, bracket are mounted on bottom cover 6, and exhaust outlet 2a is machined with incline structure, and the top processing of corresponding valve body 2 is sloping
Structure, the sealed pad lid 8 of gasket 9 are mounted on ramp structure, and the side of valve body 2 is provided with annular groove, setting in annular groove
There is sealing ring 10, the middle part that bracket is 5 is machined with raised 5a, and spring 7 is arranged on raised 5a, and the upper end of spring 7 is contradicted floating
Inside son 4.
The utility model is not limited to above-described embodiment, on the basis of technical solution disclosed by the utility model, this
For the technical staff in field according to disclosed technology contents, not needing creative labor can be special to some of which technology
Sign makes some replacements and deformation, these replacements and deformation are within the protection scope of the present utility model.
