Abstract

The utility model relates to a novel flange gasket which comprises a flange gasket body, wave-tooth skeletons, outer side rubber rings and inner side rubber rings. The flange gasket body is formed by the metal skeletons and expanded graphite materials in a combined mode, and the inner side rubber rings are arranged at the positions close to the center of the flange gasket body and connected with the outer side rubber rings. The outer side rubber rings are connected with the wave-tooth skeletons, multiple structures composed of the wave-tooth skeletons, the outer side rubber rings and the inner side rubber rings are arranged in the flange gasket body, and other spaces of the flange gasket body are filled with the graphite filling materials. The novel flange gasket is simple in structure, wide in application range and good in sealing performance, and the better sealing performance is achieved under the conditions of normal assembly stress and medium pressure.

Description

A kind of novel flange pad
Technical field
The utility model relates to a kind of novel flange pad, belongs to industrial goods field.
Background technique
There are various flange gaskets in the market, be mainly divided into metallic shim, nonmetallic gasket and combined type pad.For the internal structure of pad, be exactly the most successfully ripple tooth composite structure pad at present, but at the flange gasket that much the higher field of sealing requirements is required in a hurry the better new structure of a kind of performance.
Model utility content
The utility model, for the problems referred to above, provides a kind of novel flange pad, significantly improves the sealing of pad from force structure and principle, and improves to a certain extent corrosion resistance, and its technological scheme adopting is as follows:
A kind of novel flange pad, comprise flange gasket main body, ripple dentary frame, outside rubber ring, inner side rubber ring, described flange gasket base metal skeleton and expanded graphite meterial are composited, described inner side rubber ring is arranged at the entad of flange gasket main body, and inner side rubber ring is connected with outside rubber ring, described outside rubber ring is connected with ripple dentary frame, in described flange gasket main body, be provided with multiple structures that are made up of ripple dentary frame, outside rubber ring and inner side rubber ring, other spaces of flange gasket main body are filled by graphite-filled material.
The upper and lower surface of novel flange pad metal frame arranges the concentric grooves mutually staggering and forms ripple tooth, and the compound certain thickness expanded graphite of upper and lower surface of metal frame, forms overall Composition spacer; Described solid rubber annulus is connected on the wave tooth spacer after improvement, and two rubber ring diameters increase successively, are all greater than the maximum ga(u)ge of wave tooth spacer.The corrugated serrated compound gasket of described solid rubber annulus and described amendment is by being fastenedly connected.
On the basis of technique scheme, the diameter of inner side rubber ring is greater than the diameter of outside rubber ring.
On the basis of technique scheme, also comprise v-shaped structure, described v-shaped structure is arranged at the edge of flange gasket main body, is convenient to adjust flange gasket.
The utlity model has following advantage: simple in structure, there is wider application area and good sealing, and under normal assembling stress and middle press strip part, the utlity model has better sealability.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model cross-sectional configuration schematic diagram.
1. flange gasket main body, 2. ripple dentary frame, 3. outside rubber ring, 4. inner side rubber ring, 5.V shape structure.
Embodiment
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As depicted in figs. 1 and 2, a kind of novel flange pad, comprise flange gasket main body 1, ripple dentary frame 2, outside rubber ring 3, inner side rubber ring 4, described flange gasket main body 1 metal frame and expanded graphite meterial are composited, described inner side rubber ring 3 is arranged at the entad of flange gasket main body 1, and inner side rubber ring 3 is connected with outside rubber ring 4, the diameter of inner side rubber ring 4 is greater than the diameter of outside rubber ring 3, described outside rubber ring 4 is connected with ripple dentary frame 2, in described flange gasket main body 1, be provided with multiple by ripple dentary frame 2, the structure that outside rubber ring 3 and inner side rubber ring 4 form, other spaces of flange gasket main body 1 are filled by graphite-filled material, the utility model also comprises v-shaped structure, described v-shaped structure is arranged at the edge of flange gasket main body, be convenient to adjust flange gasket.
In use, after the bolt tension of flange-interface, the amount of deformation of inner side of the present utility model rubber ring has reached more than 40%, outside rubber ring distortion also approaches 30%, be enough to reach air-proof condition, therefore, the main sealing part of flange-interface is by rubber ring inside pad in action.Make flange gasket when distortion when the amount of deformation of rubber ring reaches, ripple dentary frame, outside rubber ring and inner side rubber ring three seal jointly.Rubber ring is subject to the pressure deformation displacement laterally of pipeline internal medium, oval corrugated serrated compound gasket will bear the stress forming after bolt tension, produce corresponding distortion, together with the built-in metal skeleton that turns to one with overall sulfur, effectively control the displacement of inner side rubber ring, and sealing effect is played to booster action.Due to triple seal effect of the present utility model, make the utlity model has wider application area and have better sealing.
With way of example, the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
