Description
Technical field
The utility model relates to the parts of motor bike, the oil separator that uses on especially a kind of motorcycle tank.
Background technology
Development along with society, motor bike quantity constantly increases, the pollutants of motorcycle emission such as Nitrogen oxides, hydro-carbon, carbonic oxide, particulate etc. are also serious day by day to the harm that environment causes, so restriction motor bike waste gas emission standard has all successively been formulated in countries in the world and area.China also successively issue " the GB14622-2007 motor bike pollutant emission restriction and measure operating condition method of the limit value standard of motor bike exhaust emission, China's III stage ", " GB18176-2007 trail bike pollutant emission restriction and measure operating condition method, Chinese III stage ", " GB20998-2007 motor bike and trail bike fuel evaporation pollutant emission limits and method of measurement ".
In order to reach the effluent standard of motor bike and light roadster fuel evaporation pollutant, fuel tank must take measures to guarantee the fuel oil evaporation indiffusion, guarantees the fuel oil proper flow simultaneously again.The general at present canister absorption control technology that adopts is by the fuel induction driving engine internal combustion of canister with absorption.In order to prevent that the gasoline in motor bike and the light roadster fuel tank from flowing into canister, again oil separator need be installed in fuel tank, for this reason, the applicant has developed a kind of high performance oil-gas separator on existing oil separator basis, the patent No. is 200920200596.4, but in use still there is following problem: the one, after existing high performance oil-gas separator is installed in the fuel tank the inside, fuel tank could weld, sprays paint, baking vanish, nylon material will produce agingly in the baking vanish process, influences service life of product.The 2nd, because high performance oil-gas separator is installed in the fuel tank the inside, inconvenience is installed, can't keep in repair after the damage, change, directly influence oil gas separation.The 3rd, because high performance oil-gas separator is installed in the fuel tank the inside, fuel level in tank limit for height line descends, and must influence the store oil amount of fuel tank.
Summary of the invention
In order to overcome the above-mentioned shortcoming that existing oil separator exists, what the purpose of this utility model provided a kind of simple and reasonable, easy installation and removal, good oil gas separation effect is installed in the outer oil separator of fuel tank.
The technical scheme that its technical matters that solves the utility model adopts, it comprises housing, base, needle-valve, float, spring, housing is captiveed joint with base, float is movably arranged in the housing, spring is arranged on the spring guide pillar of base, housing is provided with the canister interface, needle-valve is arranged on the needle-valve guide bracket inner chamber of housing, needle-valve guide bracket inner chamber links to each other with the canister interface by valve opening, at least be provided with two fixed orifices on the described housing, housing is captiveed joint with casing with screw by fixed orifice, and the face of joint of housing and casing is provided with seal ring.
The outer wall of described housing is provided with air extractor vent, and the needle-valve guide bracket of housing is provided with air channel, and the air chamber of casing communicates with the housing inner chamber by air extractor vent, and the housing inner chamber communicates with needle-valve guide bracket inner chamber by air channel.
Described housing is provided with relief valve connection, and relief valve connection links to each other with air channel, by spacers screw is arranged in the junction of relief valve connection and air channel.
After adopting said structure, with prior art following advantage and effect are arranged: the one since the utility model be weld at fuel tank, spray paint, baking vanish is fixed on the fuel tank by screw after finishing, not only installation, maintenance is simple and convenient, and can not be subjected to that fuel tank welds, sprays paint, the influence of baking vanish, the catabiosis of avoiding this process to produce.The 2nd, after oil level reached certain position, the elastic force that the buoyancy of float adds upper spring promoted the needle-valve close valve orifice, and the overfill that prevents to refuel influences oil gas separation.The 3rd, when motor bike normally uses, the air chamber of fuel tank communicates with the housing inner chamber by air extractor vent, the housing inner chamber communicates with needle-valve guide bracket inner chamber by air channel, can reach good oil gas separation, by air channel, relief valve connection and pad and screw, can effectively control tank pressure; When motor bike tilts, float self buoyancy and the effect of spring force under promote the needle-valve close valve orifice, can prevent that fuel oil from flowing to canister because of leakage.The 4th, can effectively improve the store oil volume of fuel tank, increase the store oil amount.
