Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is described in further detail.Hereinafter implement
Example is used for illustrating the present invention, but is not limited to the scope of the present invention.
Such as the pressure oil tank pressure-retaining valve apparatus of Fig. 1 to 3, including device body 1, its unusual part is: adopt
Device body 1 on be provided with fuel tank guide room 2, fuel tank guide room 2 side be provided with fuel tank joint 3, and
Fuel tank guides and is provided with canister guiding room 4 below room 2.Meanwhile, canister guides the lower section of room 4 to be provided with canister joint 5, in combustion
Fuel tank is provided with valve block assembly in guiding room 2, canister is provided with lower disc assembly in guiding room 4.
From the point of view of the present invention one preferably embodiment, the upper valve block assembly that the present invention uses includes valve block body
6.Simultaneously, it is contemplated that using resets needs, and is connected above master reset assembly at upper valve block body 6.The master reset assembly used
Including guiding bar 7, guiding the lower section of bar 7 to connect has upper valve block body 6, guides and is arranged with back-moving spring 8, reset bullet on bar 7
The lower end of spring 8 contacts with upper valve block body 6.Meanwhile, the lower section at upper valve block body 6 is provided with extension buffering ring 9.The most right
Answer, use lower disc assembly to include pedestal 10, pedestal 10 is provided with lower disc body 11.Further, at lower disc originally
Being provided with some discharge orifices 12 on body 11, connecting below pedestal 10 has secondary reset assembly, and secondary reset assembly is back-moving spring 8.
From the point of view of further, for air-tightness necessary during effectively promoting use, the outside of lower disc body 11 is provided with
Buffering extension limit 13, the thickness on buffering extension limit 13 is more than the thickness of lower disc body 11.
Simultaneously, it is contemplated that play the pressure balance of necessity during use, do not result in excessive impact, the discharge orifice of employing
12 at least two, equidistantly distribute each other.Certainly, it is contemplated that special applications, meet air pressure to be joined by the difference of stroke
Putting needs, discharge orifice 12 can be one or more in tri-angle-holed, slotted eye.
The operation principle of the present invention is as follows:
The effect of pressure-retaining valve apparatus essentially consists in the setting pressure reduction maintained between fuel tank and outside atmosphere, when pressure reduction reaches
During to setting value, upper and lower two the valve block bodies in valve all control to be closed by back-moving spring 8, make fuel tank and carbon
Tank isolation is come.
As it is shown in figure 1, when fuel tank internal gas pressure is higher than canister air pressure, pressure reduction is just.Now, the high pressure gram in fuel tank
Take the spring force of lower disc, make lower disc be opened.Meanwhile, in fuel tank, air-flow starts to leak, when lower disc body 11
Opening to maximum position, air-flow remains to be outflowed by two discharge orifices 12 on lower disc body 11, until with canister air pressure
Pressure reduction reaches initial set value, and top on lower disc body 11 is re-closing off by back-moving spring 8.
As in figure 2 it is shown, when fuel tank internal gas pressure is less than canister air pressure, now pressure reduction is negative.Gas high pressure gram in canister
The spring force of valve block on clothes, upper valve block is opened.Afterwards, canister air-flow enters in fuel tank, until with fuel tank internal gas pressure pressure
Difference reaches initial set value, and back-moving spring 8 is re-closing off pushing away under upper valve block.
(stop, close electromotor) when needs refuel, opens solenoid valve function, open valve block body 6.Thus, this
Gas in sample fuel tank can discharge (no matter malleation negative pressure).So, open the fuel tank cap period of the day from 11 p.m. to 1 a.m and do not have oil gas out, the most not
There will be the situation (as negative pressure does not discharges) of fuel tank cap of not opening.Coordinate the use of vacuum pump etc., it is also possible to when making oiling, open
Valve block, allows pumping gas.When so refueling, oil gas will not be discharged from oil filler, reduces exhaust of oil.
By above-mentioned character express and combine accompanying drawing it can be seen that use after the present invention, gather around and have the following advantages:
1, when pressurized fuel case positive pressure pressure exceedes restriction, valve block is made to open.Less than when limiting, pneumatic knot can be passed through
Structure, makes valve block be automatically switched off.
2, when pressurized fuel case negative pressure pressure exceedes restriction, valve block is made to open；Less than when limiting, valve block is automatically switched off.
3, when pressure oil tank needs to refuel, this valve of electromagnetic valve function-driven can be coordinated so that the oil gas of fuel tank will not lead to
Cross oil filler to overflow outward, meet the requirement of Abgasgesetz.
4, simple structure, it is easy to safeguard and use.
5, fuel vapor flowing between fuel tank and canister can effectively be controlled, and without carrying out large-scale redevelopment, Ji Keshi
Existing general connection.
The above is only the preferred embodiment of the present invention, is not limited to the present invention, it is noted that for this skill
For the those of ordinary skill in art field, on the premise of without departing from the technology of the present invention principle, it is also possible to make some improvement and
Modification, these improve and modification also should be regarded as protection scope of the present invention.
