Abstract
The utility model provides a three-way pipe of a fuel oil evaporating and controlling system, wherein two branch pipes are adopted at dual-head ends of the three-way pipe; the two branch pipes at the dual-head ends are opposite to a branch pipe at the single-head end; a baffle plate is arranged in the inner chamber at the intersection of three branch pipes and positioned between the interfaces of the inner chambers of the two branch pipes at the dual-head ends; and the bottom of the inner chamber of the branch pipe at the single-head end is lower than that of the inner chambers of the two branch pipes at the dual-head ends. By virtue of the technical scheme, a fuel oil evaporation and emission control pipeline can be arranged on a vehicle frame more normatively and compactly, and the used pipe clamps are less, thereby reducing cost; meanwhile, the air blockage of the three-way pipe caused by the fuel oil conglomeration is also effectively avoided.
Description
Technical field
The utility model relates to a kind of three-way pipe, especially the fuel evaporation control system three-way pipe.
Background technique
Existing Pollutant of Evaporated Gasoline Vehicle emission control systems mainly includes charcoal jar, suction tude, outlet pipe and negative pressure pipe; suction tude is connected between charcoal jar and the fuel tank; outlet pipe and negative pressure pipe are connected between charcoal jar and the Carburetor, and the toppling valve that the gasoline in the fuel tank when preventing that vehicle from toppling over enters into the charcoal jar usually also is installed on the suction tude.On motorcycle, the charcoal jar is fixedly mounted on the vehicle frame, and suction tude, outlet pipe and negative pressure pipe are generally flexible pipe, because mounted component is more on the vehicle frame, compact structure, above-mentioned flexible pipe is difficult to assurance and bending do not occur in the use, suction tude especially, and the user who has is the dismounting of fuel tank for convenience, suction tude can be extended, suction tude behind the lengthening is positioned on the vehicle frame pell-mell, and the bending part in suction tude just gathers fuel oil easily like this, causes the suction tude stuffiness.Particularly now in order to adapt to national fuel evaporation standard, the fuel tank cap of fuel tank is totally enclosed at ordinary times, the fuel tank inner chamber is to rely on the free vent on the charcoal jar to communicate with atmosphere under the normal condition, to keep the air pressure balance in the fuel tank, guarantee to start the normal oil-feed of function, if suction tude is obstructed, then uneven negative pressure can appear in the top of oil level in the fuel tank, cause the motor oil-feed not smooth, will cause engine misses when serious, influence the normal reliable work of motor.
For avoiding occurring the problems referred to above, someone is close to fuel tank on suction tude position utilizes three-way pipe to add a Non-return air valve, be equivalent to increase a path that allows fuel tank communicate with atmosphere, even therefore suction tude near this section of charcoal jar by fuel oil or owing to other reason has been stopped up, perhaps the free vent of charcoal jar is blocked, fuel tank still can keep communicating by Non-return air valve and atmosphere, makes the negative pressure in the fuel tank can keep balance all the time, guarantees that the motor oil-feed is smooth and easy and working properly.
But, existing above-mentioned three-way pipe inner chamber is simple pipeline jointing construction in three pipe intersections, liquid can be ganged up in three arms mutually, when three-way pipe makes it when the arm at Non-return air valve place tilts putting on the vehicle frame, a little liquid gasoline of coming from suction tude under some situation can form gathering through three pipe intersections the arm at Non-return air valve place, will have influence on the normal ventilation performance of Non-return air valve after how having assembled.In addition, existing three-way pipe is generally the integral molded plastic profiled member, and three arms are respectively towards different directions, after connecting top hose, cause line arrangement in disorder easily, influence the unobstructed property of pipeline inside, pipe clamp quantity in order to fixing sebific duct is also more, is unfavorable for the cost control of car load.
The model utility content
The purpose of this utility model provides a kind of fuel evaporation control system three-way pipe that is not easy to cause the air obstruction in pipeline.
For achieving the above object, the utility model provides a kind of fuel evaporation control system three-way pipe, in three arms that are connected as a single entity, wherein two arms constitute the double end end of three-way pipe, double end end two arms and single head end arm towards opposite, inner chamber three arm intersections is provided with baffle plate, and baffle plate is between the interface of two tube cavities of double end end, and the bottom that the single head end props up tube cavity is lower than the bottom of two tube cavities of double end end.
The utility model is by being provided with baffle plate in the inner chamber of three arm intersections, can block liquid gasoline and enter into the arm that another is connected with Non-return air valve from the wherein arm of double end end, avoided gasoline to assemble in this arm and the air that causes stops up.The bottom that the single head end props up tube cavity is lower than the bottom of two tube cavities of double end end, make from the double end end wherein the arm liquid gasoline of coming can enter into smoothly in the single head end arm, and be unlikely to enter into the arm that is connected with Non-return air valve.
Further, between the upper end of baffle plate and internal chamber wall, leave the gap, baffle plate is played stop the effect of liquid gasoline, but unaffected to the ventilation between double end end two arms.
Further, two arms of double end end are parallel to each other, and the pipeline that is attached thereto just can be arranged at the enterprising professional etiquette model of vehicle frame along a direction, makes pipeline be unlikely to too in disorder, helps to guarantee that pipeline inside is unobstructed.
Further, the bottom of intersection's inner chamber is provided with the groove with single head end arm intracavity inter-connection, further plays down water conservancy diversion.
Further, double end end two arms are made the structure that is fastened and connected as a whole and that single head end arm matches in intersection's employing end face convex-concave, employing welding or bonding, and relative snapping after the moulding of employing two-part difference, technology is easy to realization.
Further, the double end end wherein be equipped with Non-return air valve on the arm, be assemblied on the three-way pipe Non-return air valve is compound, no longer utilize other flexible pipe to connect Non-return air valve, make compact structure, reliable operation.
Adopt the technical solution of the utility model, effectively avoided three-way pipe, can make the layout of control pipelines for evaporation emission of fuel oil on vehicle frame standard more simultaneously because of the air that fuel oil aggregation causes stops up, compactness, used pipe clamp is few, has reduced cost.
