It extracts.Meanwhile the clamping baffle 603 of air filter device 6 being assisted to fall into triangle positive stop lug boss 103 and round limit at the top of shut-off valve
Between boss 104.Enable entire shut-off valve that can not be rotated further by as a result,.So far, shut-off valve is connect with air filter secure fit.
In conjunction with actual from the point of view of, air outlet adapter 201 and inlet suction port 202 that the utility model uses is hard with nylon
The laemodipodiform connector of pipe press fitting connection.In this way, can be carried out with using the vehicle fuel oil evaporation discharging system of such nylon hard tube
Smooth docking.Certainly, it is contemplated that certain vehicle fuel oil evaporation discharging systems use the design of rubber hose, can also be by outlet
Connector 201 and inlet suction port 202 are designed as being pressed the flange shape connector of connection with rubber hose.Furthermore, it is contemplated that it is some special
Its fuel oil evaporation discharging system of vehicle may can also be connect using slotting mode fastly using the fast construction for inserting male contact to constitute outlet
First 201 and inlet suction port 202.In this way, can very easily with the fast slotting famale connector plug connection reserved in system.
The working principle of the utility model is as follows:
Operating condition one: power-off operating condition
As shown in figure 18, in the event of a power failure, electromagnetic coil assembly 3 is not motivated, and does not generate electromagnetic force.At this point,
The initial compression force of reset spring 5 makes valve head assembly 4 and dynamic iron core 308 be withstood on 301 inner cavity top of roll.In this way, coming
The inlet channel 204 of end cap 2, seal 205, outlet are flowed through according to this from the clean gas of air filter 903 conventional in vehicle system
Channel 203 forms charge air flow 801, and enters eventually into canister 902.
Operating condition two: energization operating condition
As shown in figure 19, in the case where energization, electromagnetic coil assembly 3 is motivated, and the electromagnetic force of generation is enough to overcome
The compression spring force of reset spring 5.Electromagnetic force adsorbs dynamic iron core 308 down as a result, and valve head assembly 4 is driven to move down.
Finally, the rubber gasket 402 in valve head assembly 4 is contacted with the fitting of seal 205 on end cap 2.Electromagnetic force at this time is still
It is further compressed the rear generated spring force bigger than initial compressed state greater than reset spring 5, so that rubber gasket
402 fit closely always with seal 205.To completely cut off inlet channel 204 and outlet passageway 203 completely, from conventional empty
The clean gas of filter 903 cannot be introduced into canister 902.
When powering off again, electromagnetic coil assembly 3 can not generate electromagnetic force, compression spring force caused by reset spring 5
Valve head assembly 4 and dynamic iron core 308 is pushed to move up, rubber gasket 402 is separated with seal 205, and inlet channel 204 and outlet are logical
Road 203 is connected to again, and charge air flow 801 is formed again.
As shown in figure 20, the utility model is applied in vehicle fuel oil evaporation emission control systems.The system packet
It includes: fuel tank, canister, Valve EGR, engine, air filter etc..Shut-off valve 901 provided by the utility model is mounted on canister 902
Between conventional air filter 903, when OBD is not monitored entire vapo(u)rization system, shut-off valve 901 is in power-off opening state,
Guarantee that the cleaned air for flowing through conventional air filter 903 enters canister 902 to be rinsed in time to canister.
When OBD needs are monitored entire vapo(u)rization system, shut-off valve 901, which is powered, is closed, and keeps canister 902 and routine empty
Connection between filter 903 disconnects, and 904 close synchronously of Valve EGR, entire vapo(u)rization system form an autonomous closure system,
OBD can monitor entire vapo(u)rization system with the presence or absence of leakage point.
It can be seen from the above written description and the attached drawings that gathering around and having the following advantages after using the utility model:
1, vapo(u)rization system can be enabled to form an autonomous closure system, monitor whether entire vapo(u)rization system deposits by OBD
In leakage point, environmental protection standard is promoted and using safe.
2, use can be matched with currently widely used canister, is needed with adapting to the different classes of canister connection of different clients
It asks, and guarantees the stability of installation and the air-tightness of actual use.
3, using independent auxiliary air filter device, filter effect is promoted.
4, shutdown, conducting switching are sensitive during working, and the canister during meeting the daily traveling of vehicle uses control needs.
5, overall structure is simple, is easily assembled and working service.
The above is only the preferred embodiment of the utility model, is not intended to limit the utility model, it is noted that
For those skilled in the art, without deviating from the technical principle of the utility model, it can also do
Several improvements and modifications out, these improvements and modifications also should be regarded as the protection scope of the utility model.
