Abstract
The utility model provides a tee connector used for a fuel evaporation control system pipeline. The tee connector is provided with a first branch pipe, a second branch pipe and a third branch pipe which are communicated with one another, the directions of the first branch pipe and the second branch pipe are reverse to that of the third branch pipe. The tee connector is characterized in that the three branch pipes are crossed in a column-shaped cavity; a baffle plate is arranged in the column-shaped cavity and causes the first branch pipe and the second branch pipe as well as the first branch pipe and the third branch pipe to realize roundabout communication; and the connection position of the third branch pipe on the column-shaped cavity is lower than that of the first branch pipe and the second branch pipe. By adopting the technical scheme provided by the utility model, air blockage due to congregation of fuel near the tee connector is effectively avoided; meanwhile, the layout of fuel evaporation emission control pipelines on a vehicle frame can be standard and compact, the pipe clamps required are less, and the cost is reduced.
Description
Technical field
The utility model relates to the pipeline tee union, especially fuel evaporation control system pipeline tee union.
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 tee union 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, make the negative pressure in the fuel tank can keep balance all the time, guarantee that the motor oil-feed is smooth and easy and working properly.
But, existing above-mentioned tee union inner chamber is simple pipeline jointing construction in three pipe intersections, liquid can be ganged up in three arms mutually, when tee union 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 tee union 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 pipeline tee union 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 pipeline tee union, have first arm, second arm and the 3rd arm that are communicated with each other, first arm and second arm and the 3rd arm towards opposite, three arms are intersected in cylinder chamber, in cylinder chamber, be provided with baffle plate, baffle plate make between first arm and second arm and first arm and the 3rd arm between realize that winding type is communicated with, the link position of the 3rd arm on cylinder chamber is lower than first arm and second arm.
During use, first arm is in order to connect Non-return air valve, second arm links to each other with fuel tank, the 3rd arm is connected with the charcoal jar, baffle plate in the cylinder chamber can block liquid gasoline and go from entering in first arm after second arm enters cylinder chamber again, has avoided gasoline to assemble in this arm and causes the air obstruction.The link position of the 3rd arm on cylinder chamber is lower than first arm and second arm, makes the gasoline that enters cylinder chamber from second arm more easily enter the 3rd arm, thereby more effectively prevents gasoline from entering first arm and cause air to stop up.
Further, the end that baffle plate is close to the 3rd arm is connected with the cylinder chamber inwall, the other end to extend between first arm and second arm and and the cylinder chamber inwall between leave the gap, this gap plays baffle plate to stop the effect of liquid gasoline, but unaffected to the ventilation between first arm and second arm.
Further, the tube chamber of second arm extends through the boss that convexedly stretches in the cylinder chamber inwall and is communicated with cylinder chamber, after boss is set, the interface of second arm and cylinder chamber is misplaced in the interface of first arm and cylinder chamber, under the acting in conjunction of baffle plate, make and form the winding type connectivity structure between first arm and second arm.
Further, cylinder chamber is a round barrel shape, and the port sealing of cylinder chamber is connected with loam cake, adopts welding or bonding after the moulding respectively, and technology is easy to realize.
Further, first arm and second arm 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.
Adopt the technical solution of the utility model, effectively avoided fuel oil to assemble near tee union and the air that causes stops up, the while can also make the layout of control pipelines for evaporation emission of fuel oil on vehicle frame standard more, compactness, and used pipe clamp is few, has reduced cost.
