Description
Technical field
The utility model belongs to sealing element field, relates generally to a kind of folder fabric seal ring assembly.
Background technology
Sealing ring is a kind of for preventing the ordinary articles of the leakages such as oil, gas and water, dust, and sealing ring is usually by having one
Rubber or plastics of fixed elasticity etc. are made, and section is mostly circular, square or trapezoidal etc..In use, it is installed in separator
Gap at, be squeezed and deform in gap, so that gap plugging be lived, play the role of sealing.In the prior art
Rubber seal using after a period of time, ring wear aggravates and spring deformed due to fatigue, corrosion after rubber seal
Entirely ineffective, service life greatly shortens, and adds the maintenance rate using equipment.
Utility model content
The utility model provides that a kind of structure novel, sealant be more, leakproofness to overcome deficiency of the prior art
Good folder fabric seal ring assembly.
The technical scheme adopted by the utility model is that：
A kind of folder fabric seal ring assembly, including annular upper press cover, multiple ring type seals and annular collet, the annular
The upper surface of upper press cover is coaxially formed with the boss of the arcuation at multiple intervals, the lower part of the annular upper press cover, the ring of annular upper press cover
The downward triangle of wedge angle is made in body section lower end, and round and smooth arc base ring is made in lower wedge angle；
It is respectively in-flanges and flanging inside and outside the ring type seal, is axially made between in-flanges and flanging
There is a ring-shaped groove, in-flanges and flanging correspond to the triangle section two side of annular upper press cover respectively, coaxial close embedded, ring
The round and smooth arc base ring of shape upper press cover corresponds to ring-shaped groove；
In-flanges, flanging, annular collet bottom surface are coaxially provided with respectively inside and outside the upper surface of the annular collet
For plane, annular collet in-flanges, flanging are in contact sealing with the in-flanges and flanging bottom surface of ring type seal.
Moreover, the sealing ring can be coaxially disposed one to three.
The advantages of the utility model and good effect:
1st, folder fabric seal ring assembly provided by the utility model includes upper press cover, multi-layer sealed circle and collet, close
Groove after in seal, when seal ring assembly is squeezed, which can be radially expanded, and form interference volume, because
More for the number of plies, interference volume is abundant, improves whole sealing effect.
2nd, the protection of upper press cover and collet to sealing ring in folder fabric seal ring assembly provided by the utility model, does not allow
Sealing ring is contacted directly with separator, avoids undue extruding, extends the service life of sealing ring.
3rd, folder fabric seal ring assembly various pieces provided by the utility model are dismountable, thus can pass through gap
Size the number of sealing ring be set or replace destroyed upper cover or pedestal, so as to reduce the loss of material.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
A kind of folder fabric seal ring assembly, including annular upper press cover 2, multiple ring type seals 3,4,5 and annular collet
6, the upper surface of the annular upper press cover is coaxially formed with the boss 1 of the arcuation at multiple intervals, and multiple boss can be with sealing device shape
Into better installation, the effect of sealing is improved, the lower part of the annular upper press cover, point is made in the ring body section lower end of annular upper press cover
Triangle 7 under angularly, and round and smooth arc base ring 15 is made in lower wedge angle.
It is respectively the countershaft of in-flanges 10 and flanging 8, in-flanges and flanging inside and outside the ring type seal
To a ring-shaped groove 9 is formed with, in-flanges and flanging correspond to the triangle section two side of annular upper press cover respectively, and coaxial close
It is embedded in, the round and smooth arc base ring of annular upper press cover corresponds to ring-shaped groove, but is not embedded in.The sealing ring cross sectional shape is " V " shape.It is close
In-flanges, flanging in seal are pressed against seal cavity inner wall be subject to upper press cover and are firmly compressed, and form sealing, are not in
Oil leakage phenomenon plays preferable sealing effect, on the other hand so that the inner wall of interior flanging and the triangle section of upper press cover lower part
Both sides are in close contact, and form secondary seal.
The sealing ring can be coaxially disposed one to three, and structure is identical, be set according to the length in seal cavity space,
The utility model sets three sealing rings.
Be coaxially provided with in-flanges 13, flanging 11 respectively inside and outside the upper surface of the annular collet, and in-flanges and
Flanging is integrated 12, and annular collet bottom surface is plane 14, in-flanges, flanging be used for the in-flanges of ring type seal and
Flanging bottom surface is in contact sealing.
This seal assembly is mounted in the seal cavity of oil cylinder separator, when it is squeezed in both sides, the sealing group
The groove of part is radially expanded, and is formed interference volume, whole sealing effect is improved, simultaneously, due to the seal assembly
In the protection to sealing ring of upper press cover and collet, sealing ring is not allowed to be contacted directly with separator, adds making for sealing ring
Use the service life.
