Description
Technical field
The present invention relates to fuel tank technical field, specifically a kind of novel fuel tank isolation valve.
Background technique
Currently, when conventional vehicle designs, oil vapour can enter in canister and pass through active carbon after volatilizing for gasoline in fuel tank
Absorption can avoid pollution environment.But automobile is in motion, will form negative pressure in engine and takes off oil vapour from active carbon
From burning in simultaneously inspiration engine, fewer and fewer so as to cause the oil vapour in canister, oil vapour is revealed from canister directly to flow
Enter into external environment, causes serious environmental pollution；And engine does not work for a long time, and negative pressure can not be formed in engine,
Make oil vapour that can not be influenced to be detached from from active carbon by negative pressure and enter engine, the oil vapour after gasoline volatilization will constantly into
Enter canister, so that directly spilling into the external world again after the activated carbon adsorption saturation in canister, causes environmental pollution.Therefore, compel to be essential
Wanting one kind can satisfy, high pressure gas, negative pressure tonifying Qi, refuel the complex working conditions such as exhaust, is discharged into the gas in fuel tank through canister
External valve gear.

Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is schematic perspective view of the invention；
Fig. 2 is internal structure cross-sectional view of the invention；
Fig. 3 is partial enlarged view at the I of Fig. 2.
Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below it is right
The present invention is further described.
As shown in Figure 1 to Figure 3, a kind of novel fuel tank isolation valve, including valve body 1, the valve body have first pipe 2,
Second pipe 3, the cavity 4 communicated with first pipe 2 and second pipe 3 are combined with spool 5, the spool 5 in the cavity 4
Top be connected with solenoid valve 6 and middle part is arranged with the spring A7 in cavity 4, be equipped in the spool 5 and themselves bottom
The elongated slot 5a communicated, the first hole 5b and the second hole 5c that communicate with elongated slot 5a are combined with slidable stem in the elongated slot 5a
8, the top of the stem 8 is connected with the spring B 9 for being fixed on elongated slot 5a, is equipped with vent cap 8a in the stem 8；
The spool 5 can through the pressure in first pipe 2 vertical shift, and after the spool 5 connects restricted movement
The positioning mechanism 9 of position；
Partition 10 is equipped in the second pipe 3, second pipe 3 is separated into two impartial branch pipe(tube)s by the partition 10
3a。
The spring that the positioning mechanism 9 is connected with castellated plates 91 and vertical plate 92 respectively including castellated plates 91, vertical plate 92, both ends
C96, the serrate slot 93 for being set to stem 8, both ends are born against in castellated plates 91 and the locating rod of serrate slot 93 94 and vertical plate 92
Connected electric pushrod 95.
The both ends of the locating rod 94 are in conehead shape and level is slidably mounted on spool 5.
The electric pushrod 95 and solenoid valve 6 are connected with automatically controlled chip 11 jointly.The automatically controlled chip 11 is PLC control
Device.
The automatically controlled chip 11 is located at the upper end of valve body 1 and is connected with protective cover 12.
The bottom of the stem 8, which is equipped with, is resisted against the boss 15 of 5 bottom of spool, and hinged on the boss 15 there are two symmetrical
The baffle 13 of arrangement.Baffle 13 avoids air trapping in elongated slot 5a, causes to remain.
The first hole 5b and the second hole 5c are communicated with two branch pipe(tube) 3a respectively.
The upper end of the spool 5 is arranged with sealing ring 14.
In use, first pipe 2 is connected with fuel tank, second pipe 3 is connected with canister.
Under natural conditions, automatically controlled chip 11 is not powered on, and valve is in close state, and spool 5 is in the least significant end of isolating valve,
Fuel tank and canister are in isolation.
Under high pressure conditions, high pressure of the spool 5 by 2 inside 35kPa of first pipe moves up spool 5 under high pressure,
Compressed spring A7 is pushed to different positions according to the big small valve core 5 of internal pressure, so that two branch pipe(tube) 3a can an opening
Or be opened simultaneously, the pressure in fuel tank is discharged into the external world through canister.To improve pressure release efficiency, spool 5 is in Xiang Shangyi
In dynamic process, the right end of locating rod 94 is resisted against at the different location in castellated plates 91 with fixed spool 5, will not be because of pressure
Decline causes spool 5 to move down, and two branch pipe(tube) 3a is made to be opened always.After pressure discharges, automatically controlled chip 11 need to be only powered,
Electric pushrod 95 drives vertical plate 92 to move to right, then castellated plates 91 and locating rod 94 are detached from against spool 5 sets back.
Under low-pressure state, low pressure of the spool 5 by -15kPa inside first pipe 2, the before this overturning of baffle 13 is opened, then
Stem 8 due to low pressure effect move down, extension spring B9, make vent cap 8a and the first hole 5b and the second hole 5c can one be opened
Or be opened simultaneously, the pressure in fuel tank is discharged into the external world through canister.To improve pressure release efficiency, the left end of locating rod 94
Different location with serrate slot 93 guarantees that the first hole 5b and the second hole 5c is opened always, pressure against to fix 8 position of stem
After release, automatically controlled chip 11 need to be only powered, electric pushrod 95 drives vertical plate 92 to move to right, then serrate slot 93 and locating rod 94
It is detached from against stem 8 sets back.
Under fueling state, automatically controlled chip 11 is powered, and starts solenoid valve 6, moves up spool 5 integrally, and capacity is not very big
Then only have the second hole 5c to be opened, hinders the risk of exhaust, in the open state between fuel tank and canister, the pressure in fuel tank can
To be discharged into the external world by canister；Capacity is larger, and the first hole 5b and the second hole 5c are opened simultaneously, and entire exhaust passage is complete
It is complete to open, accelerate the pressure release exhaust of fuel tank.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and what is described in the above embodiment and the description is only the present invention
Principle, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these variation and
