Abstract
The utility model relates to an overturning valve assembly comprising an upper joint, a lower joint, a body, a valve body assemble, a spring and a steel ball, the upper joint and the lower joint are elbows, the valve body assemble is positioned in the body, a first vent hole and a second vent hole are provided on the body, the prick tip of the valve body assemble is rightly opposite to the first vent hole, the spring and the steel ball clogs the upper end of the second vent hole. The second vent hole is communicated with the cavity between the body and the valve body assemble. When the upper joint is changed into an elbow from the straight head, the utility model reduces the height of the overturning valve assembly and the requirement of the mounting space; meanwhile, the second vent hole is communicated with the cavity between the body and the valve body assemble, without being easy to clog, the operating reliability can be ensured.
Description
Technical field
The utility model relates to motorcycle Tipping valve assembly, and it is installed between fuel tank and the canister, can keep the fuel tank inner and outer air pressure to communicate under the normal condition; When overturning, can stop the fuel oil of leakage to enter canister, thereby avoid canister to be affected, and then satisfy environmental requirement, before engine misses, keep normal air pressure in the fuel tank simultaneously, avoid the fuel tank distortion.
Background technique
Appearance along with motorcycle and trail bike fuel evaporation pollutant emission limit and method of measurement (GB20998-2007) has proposed higher environmental requirement to motorcycle.In order to satisfy such requirement, on some motorcycles, bring into use the Tipping valve assembly, the Tipping valve assembly is installed between fuel tank and the canister.The Tipping valve assembly can keep the fuel tank inner and outer air pressure to communicate under the normal condition, motorcycle energy cruising, the hole plug that when motorcycle overturns, will keep inner and outer air pressure to communicate, make fuel oil can not leak in the canister, both realized environmental protection, the motorcycle burning consequence of having avoided fuel leakage to occur again.
The Tipping valve assembly mainly is made up of upper connection, lower contact, body, valve body assembly and spring and steel ball, valve body assembly is positioned at body, upper connection, lower contact are connected in the body upper and lower end, on body, be provided with first vent and second vent, valve body assembly is positioned at first vent below, the awl point of its upper end is over against first vent, and spring and steel ball are blocked second vent upper end.
Existing Tipping valve assembly has the following disadvantages: 1, because last plane tie is a straight tube, make that whole Tipping valve assembly aspect ratio is higher, installation environment is required height, need the installing space of relative process allowance; 2, because structure is limited, make the cavity between second vent on the body and body, valve body assembly be in half logical state, stop up easily, in case stop up, what motorcycle occurred under cruising just may cause stopping working than wide-angle tilt (travelling as press-bending), and need second vent to be communicated with inside and outside the fuel tank at this moment, the reliability of work is affected; Simultaneously,, can't keep the fuel tank normal barometric pressure in the overturning process before flame-out, easily cause the fuel tank distortion damaged, bring potential safety hazard and environmentally hazardous incident in case second vent stops up.
The model utility content
At the prior art above shortcomings, the purpose of this utility model provides that a kind of requirements of installation space is low, the motorcycle Tipping valve assembly of reliable operation.
The purpose of this utility model is achieved in that the Tipping valve assembly, comprise upper connection, lower contact, body, valve body assembly, spring and steel ball, lower contact is an elbow, valve body assembly is positioned at body, body is provided with first vent and second vent, the awl point of valve body assembly is over against first vent, and spring and steel ball are blocked second vent upper end, and it is characterized in that: described upper connection is an elbow.
Further, the cavity full-mesh between described second vent and body, valve body assembly.
Compared to existing technology, the utlity model has following advantage:
1, owing to change top joint into elbow (following plane tie still adopts original elbow structure),, requirements of installation space is reduced so obviously reduced the height of Tipping valve assembly;
2, cancelled the step of the second vent position on the body, the useful wall thickness of body is kept, the cavity between this second vent and body, valve body assembly is in the all-pass state, is difficult for stopping up, and the reliable operation performance is guaranteed.

Fig. 2-the utility model shape assumption diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Referring to Fig. 1, from the figure as can be seen, the utility model Tipping valve assembly is made up of upper connection 1, lower contact 7, body 2, valve body assembly 3, spring B 6 and steel ball 5, upper connection 1, lower contact 7 are elbow, can reduce the requirement of installing space like this, upper connection 1, lower contact 7 are connected in body 2 upper and lower end.Valve body assembly 3 is positioned at body 2, on body 2, be provided with first vent 8 and second vent 9, first vent 8 and second vent 9 all are communicated with upper connection center hole 10, the awl point 11 of valve body assembly 3 upper ends is over against first vent 8, and valve body assembly 3 lower ends are supported in the lower contact 7 by spring A4.Steel ball 5 utilizes the gravity of self and under the pressure effect of spring B 6 second vent, 9 upper ends is blocked.The utility model has been cancelled the step of the second vent position on the body, and the useful wall thickness of body is not reduced, and makes cavity full-mesh between second vent and body, valve body assembly like this.
Valve body assembly 3 structures of the present utility model are the same with prior art, adopt flexible structure, can guarantee that under any circumstance awl point 11 and first vent 8 of (comprise and tumbling) valve body assembly 3 upper ends is in all the time over against state.
Fig. 2 is the utility model shape assumption diagram, and the arrow on the figure is represented installation direction, and arrow down in the time of installation.
Working principle of the present utility model:
During cruising, valve body assembly 3 be owing to the awl point 11 of gravity reason on it can stop up first vent 8, spring 6 and steel ball 5 then owing to the gravity reason with 9 shutoff of second vent, this moment is by 8 ventilations of first vent;
Inclination of vehicle is time to a certain degree, valve body assembly 3 component in the axial direction reduces, therefore the pressure of spring A4 also reduce, spring A4 can on push away first vent 8 stopped up, this moment is because cylinder combustion produces negative pressure, this negative pressure will be opened by second vent 9 of steel ball 5 shutoff under the normal condition, and this moment is by 9 ventilations of second vent; Avoided flame-out, the fuel tank distortion is impaired and even hidden danger such as fuel leakage.
8 continuation of first vent are stopped up when overturning, and overturning can cause motorcycle flame-out, and this moment, negative pressure disappeared, and second vent 9 also will be by steel ball 5 shutoff, owing to two vents are all closed, so avoided fuel leakage.
