Description
Technical field
The utility model is related to a kind of sealing ring, more particularly to a kind of y-type seal ring.
Background technology
Y-type seal ring is widely used in reciprocating sealing device, and its section is Y types, including outer lip and epipharynx.
When y-type seal ring loads groove, under pressure, because the deformation of circumferencial direction can occur for outer lip and epipharynx,
Contact stress is produced, with the increase of fluid pressure, deformation and contact stress also increase therewith, so as to reach self-styled effect.
Existing y-type seal ring, the step of angular secondary lip or wedge angle is set its contact surface more, and this design can cause
Contact stress can not be diffused into entirety well, cause contact stress excessively to concentrate on a certain position, go down for a long time, the sealing of Y types
Circle can be torn, so as to lose sealing effectiveness.
Utility model content
The technical problems to be solved in the utility model is that there is provided a kind of contact stress is equal according to above-mentioned the deficiencies in the prior art
Even y-type seal ring
The technical solution of the utility model is as follows：
A kind of new y-type seal ring, including outer lip and epipharynx；The lower end of the outer lip and the lower end of epipharynx are connected
Mounting ring is formed, the mounting ring is provided with least one screens step, and the corner of the screens step is arc angling.
Further, the screens step is arranged at the outside or inner side of the mounting ring.
Further, inclined-plane is provided with the inside of the mounting ring, the inclined-plane is outward-dipping from top to bottom.
Further, it is provided with the inside of outer secondary lip and lower outer secondary lip, the epipharynx and is provided with the outside of the outer lip
Secondary lip and lower interior secondary lip in upper, the upper outer secondary lip, lower outer secondary lip, the section of upper interior secondary lip and lower interior secondary lip are circular arc
Shape.
Further, it is provided with arc angling between the upper outer secondary lip and lower outer secondary lip, the upper interior secondary lip and lower interior
Arc angling is provided between secondary lip.
Further, the section radius of the upper outer secondary lip are less than the section radius of the lower outer secondary lip, the upper interior pair
The section radius of lip are less than the section radius of the lower interior secondary lip.
Compared with prior art, the utility model has the advantages that：（1）It is provided with arc angling, upper outer pair
Lip, lower outer secondary lip, the section of upper interior secondary lip and lower interior secondary lip are circular arc, the contact that y-type seal ring can be afforded
Stress avoids stress concentration with circular arc diffusion to reach, so as to reduce the damage of y-type seal ring, and extends making for y-type seal ring
Use the life-span；（2）The section radius of upper outer secondary lip are less than the section radius of the lower outer secondary lip, and the section radius of upper interior secondary lip are less than
The section radius of the lower interior secondary lip, upper outer secondary lip and upper interior secondary lip play main seal, and lower outer secondary lip and lower interior secondary lip rise
Sealing function is supplemented, four work simultaneously, accept stress, complement one another, while the different magnitude of interference of lip above and below building, is reduced
Outer lip bears pressure with cylinder body contact surface, decreases the pressure that bears of epipharynx and motion bar contact surface, and reduction is worn and torn, so that
Improve the sealing of y-type seal ring and increase the service life；（3）Secondary lip and lower interior secondary lip coordinate in upper, are easy to the dress of motion bar
Match somebody with somebody, and facilitate the fixation of y-type seal ring and motion bar top and bottom, can effectively prevent motion bar in the case of inoperative
Unexpected slip, the generation for a series of problems, such as causing seal failure.

Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Type is described in further detail.
As shown in figure 1, the embodiment that the utility model is provided, a kind of new y-type seal ring, including outer lip 10 and epipharynx
20.The lower end of the outer lip 10 and the lower end of epipharynx 20 are connected to form mounting ring 30, and the mounting ring 30 is provided with least
One screens step, the corner of the screens step is arc angling 31.Wherein, mounting ring 30 is used for the ditch with cylinder base
Groove is assembled, and increases sealing.Arc angling 31 herein can increase the contact area of mounting ring 30 and groove, make contact stress
It is uniformly distributed and is spread with circular arc.
In the present embodiment, screens step is arranged at the outside of the mounting ring 30.Certainly, screens step can also be arranged at
The inner side of the mounting ring 30, or inner side and outer side are provided with screens step, and it is mainly set according to the shape of groove.
The inner side of the mounting ring 30 is provided with inclined-plane 32, and the inclined-plane 32 is outward-dipping from top to bottom.Wherein, inclined-plane 32
The inner side of mounting ring 30 and the contact area of motion bar can be reduced, and then reduces friction between the two, makes motion bar activity more
Plus it is smooth.
The outside of the outer lip 10 is provided with outer secondary lip 11 and lower outer secondary lip 12, and the inner side of the epipharynx 20 is provided with
Interior secondary lip 21 and lower interior secondary lip 22, the upper outer secondary lip 11, lower outer secondary lip 12, the section of upper interior secondary lip 21 and lower interior secondary lip 22
It is circular arc.Wherein, the design of circular arc, can increase the contact area of outer lip 10 and epipharynx 20, make contact stress uniform
It is distributed and is spread with circular arc.
Arc angling 13, the upper interior secondary lip 21 and lower interior pair are provided between the upper outer secondary lip 11 and lower outer secondary lip 12
Arc angling 23 is provided between lip 22.Wherein, arc angling herein（13、23）, not only contact stress be uniformly distributed and with
Circular arc spreads, and can also play and provide deformation space for upper outer secondary lip 11, lower outer secondary lip 12, upper interior secondary lip 21 and lower interior secondary lip 22
Effect.
The section radius of the upper outer secondary lip 11 are less than the section radius of the lower outer secondary lip 12, the upper interior secondary lip 21
Section radius are less than the section radius of the lower interior secondary lip 22.Wherein, upper outer secondary lip 11 and upper interior secondary 21 main seals of lip are made
With, lower outer secondary lip 12 and lower interior secondary 22 supplement sealing functions of lip, four work simultaneously, accept stress, complement one another, and seek simultaneously
The different magnitude of interference of lip above and below making, reduction outer lip 10 bears pressure with cylinder body contact surface, decreases epipharynx 20 and activity
Bar contact surface bears pressure, reduction abrasion, so as to improve the sealing of y-type seal ring and increase the service life.
Also, upper interior secondary lip 21 and lower interior secondary lip 22 coordinate, and are easy to the assembling of motion bar, and facilitate y-type seal ring with
The fixation of motion bar top and bottom, can effectively prevent unexpected slip of the motion bar in the case of inoperative, cause sealing to be lost
The generation of a series of problems, such as effect.
In the present embodiment, arc angling is provided with（13、23、32）, upper outer secondary lip 11, lower outer secondary lip 12, upper interior secondary lip 21
And the section of lower interior secondary lip 22 is circular arc, the contact stress that y-type seal ring can be afforded with circular arc spread with up to
To stress concentration is avoided, so as to reduce the damage of y-type seal ring, and extend the service life of y-type seal ring.
Above disclosed is only the utility model preferred embodiment, can not limit the utility model with this certainly
Interest field, therefore equivalent variations made according to the utility model claim still belong to the scope that the utility model is covered.
