Description
Technical field
The utility model is related to booster relief valve part fields more particularly to a kind of booster relief valve lip type group
Close sealing structure.
Background technology
At present, turbocharging technology is increasingly subject to the pro-gaze of people, it is due to that can effectively improve engine efficiency
As one of gasoline energy epoch energy-saving and environment-friendly main trend.But the engine with supercharger with air throttle, particularly gasoline
Engine while it is working, is unclamped suddenly using supercharging technology after accelerator pedal, and the blower outlet of turbocharger is to saving
It can form the volume of an approximate closing between valve suddenly, and the impeller in compressor is due to the effect of rotatory inertia, still
Compressed air is inputted into air inlet pipe.At this point, compressor delivery pressure rises, air mass flow is reduced, and easily causes turbocharger
Surge.Therefore with the development of turbocharging technology, booster is widely used with pressure release electromagnetic valve, it can be
Quick pressure releasing is realized when release the gas pedal, prevent turbocharger surge under ECU controls.
Since pressure release electromagnetic valve is mounted on supercharger outlet and to realize quick pressure releasing, have that ventilation sectional area is big, work
The characteristics of making pressure high (up to more than 200kPa), i.e., dynamic iron core needs to overcome larger active force when solenoid valve is opened.Cause
This, traditional end face seal form needs could to provide enough electromagnetic forces when solenoid valve volume is sufficiently large, and to open solenoid valve real
Existing pressure release.But since automobile engine space is limited, the electromagnetic force that solenoid valve can provide is limited, if suffered by dynamic iron core
Resistance it is excessive, the cut-in voltage of solenoid valve will accordingly increase, and have in the case where automobile engine battery voltage scope is certain
It may make electromagnetism defective valve.How the resistance of motion reduced while sealing function is realized suffered by dynamic iron core becomes this field
The problem of research.
Utility model content
The purpose of this utility model is that：A kind of booster relief valve lip type combined sealing structure is proposed, to realize
The resistance of motion suffered by dynamic iron core is reduced while sealing function.
In order to solve the above technical problems, the utility model employs following technical solution：
A kind of booster relief valve lip type combined sealing structure, including housing, housing has the cavity that Open Side Down, shell
Valve is provided in the cavity of body and surround the valve and is coated on the winding in the cavity of housing；Cover in the cavity of housing
The seal of cavitys interior and with opening upwards, the seal bottom offers a ring through hole, is arranged at the recessed of seal
Intracavitary and the dynamic iron core being connected with the cavity wall of seal；Spring is provided between valve and dynamic iron core；It is adjacent to
The inner wall of the cavity of the housing and the outer wall of the seal are provided with support ring；The support ring and seal
Between be provided with lip-shaped ring, the lip-shaped ring includes outer lip, epipharynx, the lip-shaped ring respectively with seal, support ring and housing phase
It is adjacent to.
To avoid acting on because lip-shaped ring generates larger extruding force after by atmospheric pressure to seal, increase dynamic iron core indirectly
The resistance of motion, the outer lip of the lip-shaped ring and the angle of vertical direction are more than the angle of its epipharynx and vertical direction.
Preferably, the angle of the outer lip and vertical direction is 10 °~13 °.
Preferably, the angle of the epipharynx and vertical direction is 4 °~6 °.
Preferably, it is fillet at the lip of the epipharynx of the lip-shaped ring.The fillet of the lip of epipharynx contributes to dynamic iron core
Movement.
To improve the sealing effect of lip-shaped ring, the lip-shaped ring thickness preferably 0.5~0.6mm, the at this time expansion of lip-shaped ring
Effect is best.
Preferably, the seal or lip-shaped ring or the two are made of carbon fibre reinforced plastic.Carbon fibre reinforced plastic
Use both increased the wearability of part, extend the service life of solenoid valve, and two parts made to be produced under mutual rubbing action
Raw lubricating action, the resistance of motion are less and less.
The beneficial effects of the utility model are：Support ring on housing is installed, seal is connected in dynamic iron core, close
Envelope body bottom opens up a ring through hole, and lip-shaped ring is set between support ring and seal, and boost pressure is made to pass through on seal
Through hole with being communicated inside solenoid valve, boost pressure effect under lip-shaped ring generate expansion, interior outer lip respectively with seal, support ring
End face seal, is effectively converted into the radial seal of lip-shaped ring, while sealing effect is ensured, also substantially reduced close by contact
The atmospheric pressure suffered by body is sealed, so as to reduce the active force suffered by dynamic iron core.And pass through the angle of lip-shaped ring thickness, epipharynx and outer lip
The special designing of the lip configuration of degree and epipharynx effectively reduces radial forces of the lip-shaped ring to seal, dynamic so as to reduce
Active force suffered by iron core；By being carbon fibre reinforced plastic by the design of material of lip-shaped ring and seal, both increase part
Wearability, extends the service life of solenoid valve, and the two parts is made to generate lubricating action, movement resistance under mutual rubbing action
Power substantially reduces.
