Abstract
The utility model discloses a fuel tank cover for a motorcycle which comprises a cover body and two one-way valves arranged in parallel with reverse directions. Both ends of the one-way valves are respectively communicated with the interior of a fuel tank and the external atmosphere. The fuel tank cover for a motorcycle can efficiently control the exhaust of evaporative pollutants of the fuel tank of the motorcycle, and has long service life.
Description
[technical field]
The utility model relates to a kind of fuel tank of motor bike, and what be specifically related to is a kind of case lid device of bike tank.
[background technology]
Existing motorcycle fuel case lid generally all adopts vent hole structure, the steam that fuel oil produces when absorbing fuel tank work with the charcoal jar, with balance fuel tank pressure inside, but, the charcoal jar lost efficacy easily, can cause the fuel tank pressure inside can't balance, make the bike tank can not normal operation.
[summary of the invention]
In view of the problem that known technology exists, the purpose of this utility model just provides a kind ofly can effectively control the discharging of bike tank evaporative pollutants, the motorcycle fuel case lid of long service life.
For solving the problems of the technologies described above, the utility model is taked following technical scheme:
A kind of motorcycle fuel case lid comprises lid, and lid is provided with pore, it is characterized in that: this motorcycle fuel case lid also comprises two check valves that the direction that is arranged side by side is opposite, and the two ends of check valve are communicated with fuel tank inside and ambient atmosphere respectively.Described check valve comprises valve body, spool, valve body is provided with the through hole that is communicated with the inner and ambient atmosphere of fuel tank, and described spool is one to have the cylinder of umbrella shape end, and the umbrella shape end is made by elastomeric material, spool is located on the valve body, and described through hole is sealed in its umbrella shape end.
Adopt the motorcycle fuel case lid of technique scheme, be provided with the opposite check valve of both direction, the two ends of check valve are communicated with fuel tank inside and ambient atmosphere respectively, when tank internal pressure is too high, the umbrella shape end of one of them check valve produces distortion, corresponding valve hole is opened, unnecessary oil vapour is drained, and oil vapour can not be leaked in the atmosphere at ordinary times, so this motorcycle fuel case lid can effectively be controlled the discharging of bike tank evaporative pollutants, make it to meet the discharge value of standard code, and long service life; Cross when low when tank internal pressure, the umbrella shape end of another check valve produces distortion, and corresponding valve hole is opened, and outside air will enter fuel tank inside, the normal fuel delivery of assurance system.
[description of drawings]
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model
[specific embodiment]
Principle of work and the relevant details thereof of the utility model embodiment are described below in conjunction with accompanying drawing.
With reference to accompanying drawing 1, this motorcycle fuel case lid, comprise lid 2, lid 2 is provided with pore 1, pore 1 communicates with ambient atmosphere, lid 2 lower ends are provided with two check valves that the direction that is arranged side by side is opposite, check valve comprises valve body 4, spool 3, two check valve spools 3 are fixedly mounted on 4 li of same valve bodies side by side, the installation direction of two spools 3 is just in time opposite, corresponding two spools 3, valve body 4 are provided with two groups of through holes 5 that are communicated with the inner and ambient atmosphere of fuel tank, and described spool 3 is one to have the cylinder of umbrella shape end 6, make by Rubber Parts, its umbrella shape end 6 is with its cooresponding through hole 5 sealings, and mounted check valve lower end communicates with fuel tank inside, and the upper end communicates with ambient atmosphere by described pore 1.
Claims (2)
