It is dynamic sealing, is static sealing when axle is static, oil seal body is divided into bottom, waist, cutting edge and lip according to different parts again
Deng.
At present, conventional oil sealing is generally single elastomeric material or other macromolecular materials, the sealing ring of this structure
When being matched with housing, because sealing effectiveness is undesirable, the lubricant medium of lubricating system is easily set to leak or seepage, it is impossible to meet
Use demand, serious entail dangers to personal safety.
Utility model content
The utility model provides a kind of vapour and subtracts oil sealing, and it is undesirable to solve oil sealing sealing effect conventional at present, easily makes
Into leaking or permeate, the problem of serious entail dangers to personal safety.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：
A kind of vapour of the utility model subtracts oil sealing, including elastic sealed body, support frame, spring, groove, sealing lip and oil
Envelope, is provided with the sealing lip in the oil sealing, the sealing lip is externally connected with the elastic sealed body, the elastic sealed body
Top is provided with several grooves, and the support frame is provided with the elastic packing body, and the oil sealing sets for U shape
Put, the spring is arranged with the outside of described elastic sealed body one end, and the spring is arranged on the top of recess.
Used as a kind of optimal technical scheme of the present utility model, the elastic sealed body is fluorubber.
Used as a kind of optimal technical scheme of the present utility model, the support frame is the iron-clad of antirust treatment, and described
Support frame is set to " L " type.
As a kind of optimal technical scheme of the present utility model, the company of the top of the elastic sealed body and the sealing lip
The place of connecing is set to inclined-plane.
Used as a kind of optimal technical scheme of the present utility model, the spring is set to spring after spring.
Used as a kind of optimal technical scheme of the present utility model, the centre of the oil sealing U shape is hollow setting.
The beneficial effect that the utility model is reached is：By setting groove at the top of oil sealing, it is easy to when machine oil splashes,
Top bevel make machine oil along inclined-plane flow into groove along, can avoid machine oil flow into valve guide bushing in；Spring is arranged on recess again
Top, machine oil is not increased the sealing between oil sealing and valve guide rod along being penetrated into valve guide bushing at connector,
Avoid when oil sealing is when moving up and down, spring is got rid of because moving, and meets use requirement, improves security.
Brief description of the drawings
Accompanying drawing is used for providing being further understood to of the present utility model, and constitutes a part for specification, with this practicality
New embodiment is used to explain the utility model together, does not constitute to limitation of the present utility model.
In the accompanying drawings：
Fig. 1 is the overall structure diagram that a kind of vapour of the utility model subtracts oil sealing；
In figure：1st, elastic sealed body；2nd, support frame；3rd, spring；4th, groove；5th, sealing lip；6th, oil sealing.
Specific embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
Embodiment：As shown in figure 1, a kind of vapour of the utility model subtracts oil sealing, including elastic sealed body 1, support frame 2, bullet
Spring 3, groove 4, sealing lip 5 and oil sealing 6, are provided with sealing lip 5 in oil sealing 6, sealing lip 5 is externally connected with elastic sealed body 1, and elasticity is close
The top for sealing body 1 is provided with several grooves 4, and elastic sealed body 1 is interior to be provided with support frame 2, and oil sealing 6 is that U shape is set, bullet
Property is arranged with spring 3 on the outside of the one end of seal 1, and spring 3 is arranged on the top of recess.
Elastic sealed body 1 be fluorubber, oil sealing is one of strength member of engine valve group, at high temperature with gasoline and
Machine oil is in contact, it is therefore desirable to uses heat resistance and the excellent material of oil resistivity, thus is made using fluorubber.
Support frame 2 is the iron-clad of antirust treatment, and support frame 2 is set to " L " type, is easy to fix elastic sealed body 1,
The installation of oil sealing 6 is facilitated, the assembling positioning of sealing is preferably ensure that.
5 junction is set to inclined-plane at the top of elastic sealed body 1 and sealing, is easy to make the machine oil of splashing along inclined-plane stream
In entering groove 4.
Spring 3 is set to spring after spring, is easy to make valve-closing closely, valve seating compress it is tight, and in valve opening
Or during closing, by increasing capacitance it is possible to increase the compactness of valve train component connection, it is to avoid produce abnormal sound because inertia force is separated
Situation occur.
The centre of the U shape of oil sealing 6 is hollow setting, is easy to the installation and removal of spring 3.
Specifically, when using, first oil sealing 6 is arranged on valve guide bushing, and connector is fixed with spring 3, when starting
When machine works, oil sealing 6 pumps along valve guide rod, and organic oil is splashed to top or the valve guide rod of valve guide bushing
On, machine oil is flowed into groove 4 along the inclined-plane at the top of oil sealing 6, and spring 3 is located at oil sealing 6 with the junction of valve guide rod
Indent, good airproof performance, in preventing machine oil from penetrating into valve guide bushing from connector.
This kind of vapour subtracts oil sealing, and groove 4 is set by the top of oil sealing 6, is easy to when machine oil splashes, and top bevel makes machine oil
Along inclined-plane flow into groove 4 along, can avoid machine oil flow into valve guide bushing in；Spring 3 is arranged on the top of recess again, makes machine oil
The sealing between oil sealing 6 and valve guide rod will not be increased along being penetrated into valve guide bushing at connector, it is to avoid work as oil sealing
6 when being moved up and down, and spring 3 is got rid of because moving, and meets use requirement, improves security.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, this is not limited to
