Description
Technical field
This utility model relates to flange seal packing ring during joint seal of flanges, belongs to potted component technical field.
Background technology
The commonly used flat rubber washer of traditional joint seal of flanges, its pressure that can bear is relatively low, the most all
Being limited to 1.6MPa pressure used below, additionally, due to its simple in construction, the safety therefore sealed is poor.And current rubber blanket
The height of circle its rigidity selects to there is following awkward situation: although the high pressure height of rubber hardness but its sealing property are owed
Good, and if rubber hardness is low, although sealing performance is quite a lot of, but sealing gasket is easily pressed within and breaks through, and causes leakage.The most also
Do not have a kind of reasonable seal washer can realize hardness (pressure) and sealing property is the most excellent.
Utility model content
Problem to be solved in the utility model is to provide a kind of face-flange connection rubber gasket, and it has peace
The feature that dress accurate positioning, sealingly secure and stability are high.Meanwhile, voltage endurance capability of the present utility model can reach 6 Mpa, far
Far above existing seal washer.
A kind of novel flange seal packing ring of this utility model, is characterized in that: the cross sectional shape of flange seal packing ring is: outer
Portion is rectangle, the internal combinative structure combined for O shape.Wherein, the size in cross section includes the long a of rectangle, the radius of wide b, O shape
For r, 2r >=b.From the above, it can be seen that the coalition that this utility model flange seal packing ring is flange circle and O, i.e. flat
Designing the annular O of a disjunctor at the inner ring of board-like rubber washer, this kind of cross sectional shape enhances this utility model flange
The sealing property of seal washer.
As a kind of optimal way of the present utility model, in this utility model flange seal packing ring: O shape and rectangle intersection
Chord length is c, c=b.So, the intersection of O shape and rectangle does not haves downward depression, thus without because of stress problem
Make seal washer rupture from there to come, thus extend the service life of seal washer.
As a kind of improved procedure of the present utility model, in this utility model flange seal packing ring: set in the inside of rectangle
The steel sheet skeleton 4 built-in steel sheet skeleton structure being equipped with annular can strengthen rigidity and the resistance to compression voltage endurance capability of seal washer so that it is
Can use safely below 6Mpa pressure.As a kind of optimal way, the thickness of built-in steel sheet skeleton is 0.5 ~ 4mm, its tool
Depending on the size of body is according to the width b of rectangle.
It is integrated to improve the bonding force of built-in steel sheet skeleton and outside rubber, built-in steel sheet skeleton and outside rubber
Formula sulfuration overall structure, wherein, needs to carry out the surfaces such as sandblasting, ball blast and coating adhesive and processes before the sulfuration of built-in steel sheet skeleton,
So that it is guaranteed that the overall high intensity of flange seal packing ring.
In order to adapt to the demand of pipeline conveying different medium, packing ring can use different quality of rubber materials to produce: specifically
Saying, the material of packing ring can use EPDM rubber (ethylene propylene diene rubber) or NBR rubber (nitrile rubber).Wherein, EPDM rubber
The ageing-resistant performance of material is good, and is difficult to chemical mediator reacts；NBR rubber material may insure that the oil resistivity of product
Energy.
The advantage of this utility model flange seal packing ring is: one, the cross sectional shape of this utility model flange seal packing ring
Advantage is: flange adds the fillet that there is an indent man-hour, when this utility model flange seal packing ring be assemblied in two flanges it
Between time, on flange, the fillet of indent just matches with O shape of the present utility model so that accurate positioning between the two, and both are tight
The arc surface being close to close makes sealing property improve, even if having worn and torn in cooperation face, arc surface can also compensate abrasion automatically；By
Arc surface in packing ring is higher than plane, and when being impacted by liquid or gas, the arc surface of flange seal packing ring can be by tightly
It is stuck at the fillet of flange indent, without being washed out, therefore this utility model flange seal packing ring can bear bigger pressure
Power, also ensure that the safety and stability of sealing；Two, this utility model is logical at the center of the most flat rubber washer of rectangle
The method crossing integral type sulfuration has inserted the steel sheet skeleton of annular, and the existence of the steel sheet skeleton of annular uses this utility model flange
Rigidity and the pressure performance of seal washer greatly improve；Three, sandblasting, ball blast and painting bonding are carried out before the sulfuration of built-in steel sheet skeleton
The surfaces such as agent process, and improve the bonding force of built-in steel sheet skeleton and rubber, so that it is guaranteed that the entirety of flange seal packing ring is high-strength
Degree；Four, the selection of elastomeric material improves the service life of product.On innovation improve improve joint seal of flanges resistance to pressure
Energy and safety.
In a word, the sealingly secure of this utility model flange seal packing ring, performance for stability are greatly improved, and have installation
The feature of accurate positioning.Meanwhile, the voltage endurance capability of this utility model flange seal packing ring reaches 6 MPa, therefore can be at 6MPa
Hereinafter use safely.
