The utility model discloses a resistant high pressure seal ring can play the effect of the Y type that supports sealing washer main part through setting up cascaded direction circle on the one hand, has improved the seal pressure of sealing washer, the straight cylinder design of the cascaded direction of on the other hand circle inner wall has the guide effect, in addition, it is sealed that the outer wall of first ladder has formed the second way, has improved the sealing performance of sealing washer.
Description
Technical field
This utility model relates to a kind of mechanical sealing member, particularly to a kind of resistance to height with staged guide collar
Pressure seal ring.
Background technology
Existing y-shaped ring bearing capacity limited (up to 16MPa), during pressure height, root is easy to
Now bite phenomenon, therefore when high pressure occasion, typically add back-up ring at y-shaped ring root and form combination sealing
To prevent from biting.But in high-voltage high-speed motion occasion, the occasion that especially reciprocating frequency is higher, Y type
Sealing ring lip will soon cause seal failure to cause dielectric leakage after wearing and tearing, and Y shape seals
Circle itself does not have guide effect, when eccentric motion occasion, easily causes sealing ring one lateral wearing to aggravate,
So it is generally required to coordinate fairlead to use, the occasion at limited space then cannot install fairlead.
Utility model content
For solving above-mentioned technical problem, the utility model discloses and a kind of there is the high pressure resistant of staged guide collar
Sealing ring, including be provided with outer lip, epipharynx, the y-type seal ring main body of root and with y-type seal ring main body
The staged guide collar that root connects, the inwall of described staged guide collar designs for straight barrel type, described root
Inner side is positioned at the position below epipharynx and is provided with guiding ring recess, described staged guide collar include the first ladder, the
Two ladders and the 3rd ladder, described first ladder is arranged on the bottom surface of root, and described second ladder is arranged on
In guiding ring recess, described 3rd ladder protrudes in the outside of the second ladder and is positioned at y-type seal ring body interior.
As further improvement of the utility model, described first step horizontal arrange, described second ladder and
3rd step inclined is arranged.
As further improvement of the utility model, formed between described 3rd ladder and the sidewall of the second ladder
Oil storage tank.
As further improvement of the utility model, the height of described second ladder is more than the height of the first ladder,
The height of described 3rd ladder is between the height of the first ladder and the second ladder.
The beneficial effects of the utility model are:
High-pressure-resistant sealed circle of the present utility model, by arranging staged guide collar, on the one hand can play support Y
The effect of RunddichtringO main body, improves the voltage endurance capability of sealing ring；On the other hand staged guide collar inwall
Straight barrel type design there is guide effect；Seal it addition, the outer wall of the first ladder defines second, improve
The sealing property of sealing ring.
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 cross-sectional view of the present utility model.
Labelling in figure: 1-Y RunddichtringO main body；11-outer lip；12-epipharynx；13-root；2-staged guides
Circle；21-the first ladder；22-the second ladder；23-the 3rd ladder；24-oil storage tank.
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 high-pressure-resistant sealed circle with staged guide collar, including be provided with outer lip 11,
Epipharynx 12, the y-type seal ring main body 1 of root 13 and be connected with the root 13 of y-type seal ring main body 1
Staged guide collar 2.
The inwall of staged guide collar 2 designs for straight barrel type, can play guiding when piston rod moves wherein
, even if there is the occasion of eccentric motion in effect, it is also possible to outside ensureing that piston rod is with y-shaped ring main body 1
Lip 11 and epipharynx 12 are concentric.
The material of staged guide collar 2 is the PTFE filling copper powder, and it is close that stepped structure plays support Y type
While seal main body 1 effect, additionally it is possible to improve the voltage endurance capability of sealing ring, reach as high as 30MPa.
Being positioned at the position below epipharynx 12 inside root 13 and be provided with guiding ring recess, staged guide collar 2 includes
Horizontally disposed first ladder 21, the second ladder 22 and the 3rd ladder 23 being obliquely installed, the first ladder 21
Being arranged on the bottom surface of root 13, the second ladder 22 is arranged in guiding ring recess, and the 3rd ladder 23 protrudes the
The outside of two ladders 22 to be positioned at y-type seal ring main body 1 internal.Wherein, the height of the second ladder 22 is big
In the height of the first ladder 21, the height of the 3rd ladder 23 is positioned at the first ladder 21 and the second ladder 22
Between height.
Oil storage tank 24 is formed, it is possible to storing lubricating grease between 3rd ladder 23 and the sidewall of the second ladder 22,
Improve the persistency of lubricant effect.
The outer wall of the first ladder 21 adds again one sealing on the basis of outer lip 11, forms second close
Envelope, makes sealing effectiveness more preferable, and service life is longer, even if after outer lip 11 occurs mild wear, overall close
Envelope effect is still able to guarantee.
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.
