Abstract
A kind of turbocharged engine valve oil seal, it is related to automobile processing and manufacturing apparatus field, including skeleton, rubber bodies and spring, the rubber bodies are fixed and are fitted on the skeleton, sealing lip is provided with above the rubber bodies, the spring is attached to outside the rubber bodies at sealing lip；Be provided with some raised annular adhesive tape on the inside of the sealing lip, make the radial section undulate of the sealing lip, fixed in the annular adhesive tape at the sealing lip and be coated with bracing ring.Adapt to turbocharged engine high temperature, the actual working environment of high pressure so that sealing property increase, be not susceptible to oil leakage, and then increase the service life of valve oil seal.
Description
Technical field
It the utility model is related to automobile processing and manufacturing apparatus field, and in particular to a kind of turbocharged engine valve oil
Envelope.
Background technology
Automobile engine is done work to produce power by fuel in gas in-cylinder combustion.Because the fuel quantity of input is inhaled
Enter the limitation of cylinder air amount, therefore power output caused by engine can be also restricted.Under prior art conditions,
Turbocharger is the only mechanical device for making engine increase power output in the case where operating efficiency does not reduce.It is pressurized it
Afterwards, the pressure and temperature that engine is waited at work all raises significantly, so as to which the mechanical performance of engine, greasy property all can be by
To influence, service life of aeroengine greatly shortens.Most it will be evident that after supercharging, temperature, pressure enhancing at valve oil seal,
The sealing function of traditional valve oil sealing declines, and oil leakage easily occurs, and because high temperature, the working environment of high pressure, cause machine
Rusting knot produces carbon distribution so that the service life of traditional valve oil sealing greatly shortens.Therefore, a kind of sealing property of research and development is needed badly more
It is good, it is not susceptible to lubricating oil leakage, the valve oil seal of service life length.
The content of the invention
In order to solve above-mentioned problem of the prior art, the utility model provides a kind of turbocharged engine valve oil
Envelope, adapts to turbocharged engine high temperature, the actual working environment of high pressure so that sealing property increase, is not susceptible to machine oil
Leakage, and then increase the service life of valve oil seal.
The purpose of this utility model can be realized by following technical proposal：A kind of turbocharged engine valve oil
Envelope, including skeleton, rubber bodies and spring, the rubber bodies are fixed and are fitted on the skeleton, are provided with above the rubber bodies
Sealing lip, the spring are attached to outside the rubber bodies at sealing lip；Some raised annulars are provided with the inside of the sealing lip
Adhesive tape, makes the radial section undulate of the sealing lip, in the annular adhesive tape at the sealing lip fixation be coated with bracing ring.
For the utility model by changing the structure at sealing lip, each projection fixation is coated with bracing ring, is keeping close
In the state of toughness is constant at envelope lip, increase sealing rigidity, weaken stress changes caused by carbon distribution and sealing lip aging.
Preferably, the rubber bodies bottom is coated with static lip, and the static lip protrudes the skeleton bottom, uses
When, the static lip and engine body are in sealing contact, reduce the high temperature discharged after engine acting, high pressure exhaust gas to sealing
The influence of lip.
Preferably, the sealing lip back is provided with annular groove, and the spring is fixed in the annular groove.
Preferably, the bracing ring is spring steel steel ring.
Resultant effect includes caused by the utility model：
The utility model simple structure is reasonable, pass through at sealing lip add bracing ring, it is ensured that valve oil seal can high temperature,
Steady operation in the environment of high pressure, the sealing of valve oil seal is improved, reduce oil leakage, reduce because of the work of high temperature, high pressure
Cause the probability of machine oil sintering generation carbon distribution as environment, so as to greatly improve the service life of valve oil seal.
Brief description of the drawings
Fig. 1 is the utility model embodiment radial section structural representation.
Fig. 2 is the structural representation of the utility model embodiment A structures.
Wherein, identical part identical reference in the accompanying drawings；Accompanying drawing is not drawn according to the ratio of reality.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Embodiment
A kind of turbocharged engine valve oil seal, including skeleton 1, rubber bodies 2 and spring 3, the rubber bodies 2 are fixed
It is fitted on the skeleton 1, the top of rubber bodies 2 is provided with sealing lip 21, and the spring 3 is attached to the institute at sealing lip 21
State outside rubber bodies 2；The inner side of sealing lip 21 is provided with some raised annular adhesive tape, and the radial section for making the sealing lip 21 is in
Waveform, in the annular adhesive tape at the sealing lip 21 fixation be coated with bracing ring 4.
The present embodiment by change at sealing lip 21 structure, each projection fixation is coated with bracing ring 4, keep it is close
In the state of toughness is constant at envelope lip 21, increase sealing rigidity, weaken stress changes caused by carbon distribution and the aging of sealing lip 21.Institute
State the back of sealing lip 21 and be provided with annular groove, the spring 3 is fixed in the annular groove.
In addition, the bottom of rubber bodies 2 is coated with static lip 22, the static lip 22 protrudes the bottom of skeleton 1,
In use, the static lip 22 and engine body are in sealing contact, high temperature, the high pressure exhaust gas discharged after engine acting are reduced
Influence to sealing lip 21.
Finally, the bracing ring 4 is the steel ring of spring steel, has good toughness.
The utility model is described above with reference to preferred embodiment, but the scope of protection of the utility model is not
Limited to this, any all technical schemes fallen within the scope of the appended claims are in the scope of protection of the utility model.
In the case of not departing from the scope of the utility model, various improvement can be carried out to it and can be replaced with equivalent therein
Part.Especially, as long as structural hazard is not present, the every technical characteristic being previously mentioned in each embodiment can be in any way
Combine.
