Abstract
The utility model discloses a sealing washer suitable for different medium occasion, including the sealing washer main part, sealing washer main part both sides respectively are equipped with a seal lip group that comprises epipharynx and outer lip, form V type seal groove between epipharynx and the outer lip, be equipped with V type supporting spring in the V type seal groove, the outer circumference of sealing washer main part still is equipped with the seal groove. The utility model discloses a sealing washer suitable for different medium occasion is through respectively setting up seal lip group in sealing washer main part both sides, can separate the different working medium of sealing washer both sides, has reduced the quantity of using the sealing washer, has reduced the processing cost of cylinder body to adopt V type supporting spring, initial sealed effectual, the seal lip can be according to pressure medium's different automatically regulated tension, in order to reach optimal frictional force and sealed effect moreover.
Description
Technical field
This utility model relates to a kind of mechanical sealing member, is applicable to the close of different medium occasion particularly to a kind of
Seal.
Background technology
Sealing ring, according to the difference of use occasion, is generally divided into Pneumatic sealing ring and hydraulic sealing ring two kinds, pin
Need to select different sealing rings to different working medias.Keep apart two kinds of working medias needing in the past
Occasion, needs to be respectively provided with a sealing ring in the both sides of rotating shaft just it is achieved that not only take up room relatively big,
Install comparatively laborious, and the cylinder body coordinated with rotating shaft need to process two for the groove placing sealing ring,
Increase difficulty of processing, improve production cost.
Utility model content
For solving above-mentioned technical problem, the utility model discloses a kind of sealing being applicable to different medium occasion
Circle, including sealing ring main body, described sealing ring main body both ends of the surface be respectively provided with one be made up of epipharynx and outer lip close
Envelope lip group, forms V-seal groove, is provided with V in described V-seal groove between described epipharynx and outer lip
Type supports spring, and described sealing ring main body excircle is additionally provided with seal groove.
The beneficial effects of the utility model are:
The sealing ring of different medium occasion that is applicable to of the present utility model is by respectively arranging in sealing ring main body both sides
One sealing lip group, it is possible to by the different operating medium separate of sealing ring both sides, decrease and use sealing ring
Quantity, reduces the processing cost of cylinder body, and uses V-type to support spring, and initial sealing is effective, and
And sealing lip can be automatically adjusted tension force according to the difference of pressure medium, to reach optimal frictional force and close
Envelope effect.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, below will be to institute in embodiment
The accompanying drawing used is needed to be briefly described, it should be apparent that, the accompanying drawing in describing below is only this practicality
Some novel embodiments, for those of ordinary skill in the art, are not paying creative work
Under premise, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is sectional structure chart of the present utility model；
Fig. 2 is use state diagram of the present utility model.
Labelling in figure: 1-sealing ring main body；2-epipharynx；3-outer lip；4-V type sealed groove；5-V type supports
Spring；6-seal groove；7-rotating shaft；8-cylinder body.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment
Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real
Execute example rather than whole embodiments.
As it is shown in figure 1, a kind of sealing ring being applicable to different medium occasion, including sealing ring main body 1, seal
Circle main body 1 both ends of the surface are respectively provided with a sealing lip group being made up of epipharynx 2 and outer lip 3, epipharynx 2 and outer lip 3
Between formed V-seal groove 4, be provided with in V-seal groove 4 V-type support spring 5, sealing ring main body
Excircle is additionally provided with seal groove 6.
As in figure 2 it is shown, this utility model is in use, only one need to be arranged between rotating shaft 7 and cylinder body 8
Sealing ring, cylinder body 8 the most only need to process a groove placing sealing ring, and two groups of sealing lip groups can be by
The different operating medium separate of sealing ring both sides, decreases the quantity using sealing ring, also reduces simultaneously
The processing cost of cylinder body；And using V-type to support spring 5, initial sealing is effective, and sealing lip can
It is automatically adjusted tension force, to reach optimal frictional force and sealing effectiveness with the difference according to pressure medium.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model,
All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
Within protection domain of the present utility model should be included in.
