Description
Technical field
The utility model relates to ring pads, in particular to a kind of ring pads with sealing, insulation performance.
Background technique
In the Process Equipment of every field industrial department, gasket seal is occupied an important position, especially in petroleum, change
In industrial and commercial bank's industry, it often there is a need for being able to some gasket seals with insulation performance；It is presently used in the ring joint face of connecting pipe
(RTJ) the common ring pads on flange are metal material, and due to the electric conductivity of metal material, this ring pads can not generate insulation
Effect；And can the ring pads of insulation generally use phenolic resin, the big small feature of resilience of rigidity leads to sealing performance not
It is good.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of structures simple, good insulation preformance, good seal performance, dimension
Protect convenient ring pads.
In order to achieve the above objectives, the technical solution of the utility model is as follows:
A kind of ring pads, including the ring pads main body being made of insulating material, the ring pads main body is cirque structure, ring pads master
The lateral surface of body is equipped with the boss being arranged along ring pads main body circumferencial direction, and the upper and lower surface of boss is to extend on the inside of boss
Inclined-plane forms notch between inclined-plane and ring pads main body, the angle between inclined-plane and horizontal plane is 30-60 °；It is removable in ring pads main body
That unloads is arranged an elastic ring cushion, and elastic ring cushion is equipped with a notch identical with boss size；After elastic ring cushion installation, boss position
In in this notch.
In one embodiment of the utility model, the thickness of the elastic ring cushion is greater than the thickness of boss.
In one embodiment of the utility model, the lateral surface of the boss is equipped with elastic coating.
In one embodiment of the utility model, elastic coating thickness adds boss thickness to be equal to elastic ring cushion thickness.
In one embodiment of the utility model, the ring pads main body is by phenolic aldehyde clamping cloth resin or the strong resin of epoxy glass
Material is made.
In one embodiment of the utility model, the elastic ring cushion is made of neoprene or nitrile rubber material.
In one embodiment of the utility model, elastic coating is rubber layer.
In one embodiment of the utility model, the height of boss is equal to 1/3 ring pads body height.
In one embodiment of the utility model, ring pads body cross-section is ellipse or octagonal.
Through the above technical solutions, the beneficial effects of the utility model are:
The utility model structure is simple, good insulation preformance, good seal performance, can self-changeable after elastic ring cushion damage；
Furthermore since boss is equipped with inclined-plane, part of it can enter lacking between inclined-plane and ring pads main body to elastic ring cushion when compressed
In mouthful, such elastic ring cushion is not easy to be squeezed bad, improves service life.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the utility model cross section stereo schematic diagram；
Fig. 2 is the utility model cross-sectional view；
10, ring pads main body 11, boss 12, inclined-plane 13, notch 20, elastic ring cushion.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Referring to figure 1 and figure 2, the utility model discloses a kind of ring pads, including the ring pads master being made of insulating material
Body 10, ring pads main body are cirque structure, and ring pads body cross-section is ellipse, are also possible to the suitable ring joint face such as octagonal
(RTJ) shape of the slot of flange；The lateral surface of ring pads main body is equipped with the boss 11 being arranged along ring pads main body circumferencial direction, boss
Height be equal to 1/3 ring pads body height, other height also can be set according to actual needs, be not added and repeat herein；Boss
Upper and lower surface be that notch 13, inclined-plane and horizontal plane are formed between inclined-plane and ring pads main body to the inclined-plane 12 extended on the inside of boss
Between angle be 30-60 °, the utility model is preferably 45 °；An elastic ring cushion 20, bullet are removably arranged in ring pads main body
Property ring pads after damage can with self-changeable, elastic ring cushion be equipped with a notch identical with boss size；Elastic ring cushion installation
Afterwards, boss is located in this notch.
The thickness of elastic ring cushion is greater than the thickness of boss, and the lateral surface of boss is equipped with elastic coating, and elastic coating is rubber
The setting of glue-line, elastic coating reduces the abrasion between boss and flange contact facings.
Elastic coating thickness adds boss thickness to be equal to elastic ring cushion thickness, makes the overall dimensions of ring pads consistent, improves
Stability.
Ring pads main body is made of phenolic aldehyde clamping cloth resin or the strong resin material of epoxy glass, ensure that the insulation performance of ring pads；
Elastic ring cushion is made of neoprene or nitrile rubber material, ensure that the sealing performance of ring pads.
The utility model when being installed on ring joint face (RTJ) flange, elastic ring cushion due to good resilience itself,
Elastic ring cushion part of it when being pressurized can enter in the notch between inclined-plane and ring pads main body, elastic ring cushion and flange sealing surface
Between form good leakproofness, and make can not be conductive between two panels flange for ring pads main body, protects flange not by electrochemical corrosion.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
