Description
Technical field
The present invention relates to a kind of valve, more particularly to a kind of fuel tank isolation solenoid valve.
Background technology
In typical discharge vaporization management system, fuel-steam is discharged into canister by fuel tank GVV valves.Canister contains
Activated carbon, there is the function of absorption fuel-steam.After engine start, fresh air is inhaled into canister, and charcoal absorption
Fuel-steam be sent to together engine participate in burning.But in plug-in hybrid electric vehicle type, long-term use of electricity be present
The pattern traveling of dynamic driving, canister is not desorbed function under electric model.If the steam in fuel tank is discharged into canister always,
Easily cause canister saturation.Fuel-steam after saturation can be directly discharged in environment, cause environmental pollution.Therefore one is needed
Fuel tank isolation valve, the steam pressure of fuel tank is sealed in fuel tank.Fuel tank isolation valve is opened when needing and reducing tank pressure, with
Just the fuel-steam of high pressure can be discharged in canister and store.
A kind of situation be present, when group refueling, it is desirable to which the high pressure fuel steam of fuel tank memory storage can be flowed into quickly
Canister, to reduce the stand-by period of refueling.Fuel tank steam flow rate may result in very much the logical of other positions in evaporative emissions system soon
Air-valve blocks, such as FLVV valves.Therefore there is a kind of design to fuel tank isolation valve it is expected, it is desirable to which fuel-steam is with a kind of controlled
Rate of release flows into canister, on the one hand accelerates rate of release, reduces the stand-by period of refueling；On the one hand control speed can not be too big,
To avoid causing the blocking of fuel tank FLVV valves.
In prior disclosed Chinese patent（Patent No.：CN103328805A）In, pass through the size and spring of pressure
Cooperation control lifting piston up-down, so as to controlling whether big passage is opened.When tank pressure is higher, by controlled
Passage aisle carry out flow control.When tank pressure reduces, the flow velocity of passage aisle will reduce, and spring overcoming pressure is opened big logical
Road, to increase steam flow rate.The design is needed with two springs come the too small of regulating sealing pressure, while by tonifying Qi valve block
It is integrated into same system, the built-in spring force of superfeed pressure size and magnetic valve is directly proportional.Actually with 3 springs come
Adjust the functions such as superfeed pressure, deflation speed control.And the machining comparison of coherence of spring is poor, the accumulative mistake of 3 springs
Difference is more difficult to control.Add the complexity of system and reduce finished product rate.
The content of the invention
It is an object of the invention to provide a kind of fuel tank isolation solenoid valve, its is simple in construction, easily manufactured, improves the peace of fuel tank
Quan Xing.

Fig. 7 is to be somebody's turn to do the present invention using the schematic diagram in plug-in hybrid pressure-oil tank evaporative emission control system
System is desorbed valve, high-pressure pressure sensor, fuel tank isolation valve, leak detection module etc. and formed by fuel tank, canister, canister；Oil
Evaporative emission control system is isolated into two parts, fuel tank part and canister part by case isolating valve；Travel or stop in vehicle
During, fuel-steam can produce always, and be isolated in fuel tank end by fuel tank isolation valve, and the tank pressure of isolation there may be
Malleation, it is also possible to negative pressure be present, after positive pressure pressure is more than certain value or negative pressure pressure is less than certain value, fuel tank there may be quick-fried
The risk split or caved in；When fuel tank partial pressure is too high, too high oil can be discharged by the discouraged valve passage of fuel tank isolation valve
Case pressure, fuel tank part is kept in the range of safe pressure；When fuel tank partial pressure is too low, the benefit of fuel tank isolation valve can be passed through
Air valve passage supplements tank pressure, causes fuel tank to cave in prevent tank pressure is too low.
As seen in figs. 5-6, during present invention work, when high pressure occurs in the pressure in fuel tank but it is unlikely to top and opens the first spring
105 carry out pressure release, and need to the high voltage control in fuel tank to atmospheric pressure（As refueled）When, under original state, due to magnetic valve
To close, valve core rod 303 now coordinates upper cavity seal membrane 304 to seal regulation stomata 305 from upper cavity, in lower chamber,
Support is withstood in lower chamber in the presence of back-moving spring 308, so that it can not be close by regulation stomata 305 from lower chamber
Envelope, when needing regulating oil tank pressure, by opening magnetic valve, magnet coil 302 controls valve core rod 303 to act, so that will be upper
Cavity seal membrane 304 is opened, and now tank pressure is in higher level, and steam pressure can head on support and be sealed together with lower chamber
Diaphragm 309 is closed stomata 305 is adjusted, and restricted orifice is opened up among lower chamber seal membrane 309, and high pressure draught can pass through limit
The adjusted stomata 305 of discharge orifice, epicoele direction of flow canister, it is multiple when tank pressure decreases below the elastic force of back-moving spring 308
Position spring 308 heads on support and moved down, and now adjusts stomata 305 and is opened, and more forced drafts lead to from the square of rack side wall
Air drain 310b adjusts stomata 305 with higher flow rate and direction, and avoid during this causes air-flow because initial pressure is higher
Burst outflow, and cause the other parts of oil tank system（Such as FLVV）The problem of obstruction so that tank pressure regulation is more pacified
It is complete reliable, even and if adjusting process only needs a back-moving spring 308 to realize that its structure is simpler, cost with unification bearing
Cheaper, specific safe pressure can be demarcated by back-moving spring 308.
