In the electric conductivity of metal, dentiform gasket does not have insulation performance.In different metal flanged joint, since there are current potentials for two panels flange
Difference, if galvanic corrosion can be generated using on-insulated dentiform gasket.
Utility model content
The tooth form insulating that the technical problem to be solved by the present invention is to provide a kind of structures simply, insulated enclosure performance is good
Gasket.
In order to achieve the above objectives, the technical solution of the utility model is as follows:
Tooth form insulating gasket, including annular gasket main body, the gasket body include:
One insulation spacer；
One is arranged in the first tooth profile metal pad on insulation spacer upper surface, and the first tooth profile metal pad is contacted with insulation spacer
One side be shiny surface, another side is toothed surface；
One is arranged in the second tooth profile metal pad on insulation spacer lower surface, and the second tooth profile metal pad is contacted with insulation spacer
One side be shiny surface, another side is toothed surface；
One is arranged in the first gasket in the first tooth profile metal pad toothed surface；
One is arranged in the second gasket in the second tooth profile metal pad toothed surface.
In one embodiment of the utility model, the first tooth profile metal pad and the second tooth profile metal pad pass through the side binded
Formula is fixed on insulation spacer.
In one embodiment of the utility model, the first gasket is fixed on the first tooth profile metal by way of bonding
On pad, the second gasket is fixed on the second tooth profile metal pad by way of bonding.
In one embodiment of the utility model, insulation spacer is by clamping cloth phenolic resin or glass fiber reinforced epoxy resin material
Material is made.
In one embodiment of the utility model, the first tooth profile metal pad and the second tooth profile metal pad are by stainless steel
Material is made.
In one embodiment of the utility model, the first gasket and the second gasket are by rubber or polytetrafluoroethylene (PTFE)
Material is made.
Through the above technical solutions, the beneficial effects of the utility model are:
The utility model structure is simple, insulated enclosure performance is good, and materials are convenient, at low cost, compared to traditional dentiform gasket, needs
Want lower bolt torque.
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 cross section stereo schematic diagram of the utility model；
Fig. 2 is the cross-sectional view of the utility model；
10, insulation spacer 20, the first tooth profile metal pad 30, the second tooth profile metal pad 40, the first gasket 50, second
Gasket.
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 tooth form insulating gasket, including annular gasket main body, gaskets
Main body includes insulation spacer 10, the first tooth profile metal pad 20 being arranged on insulation spacer upper surface, is arranged under insulation spacer
The second tooth profile metal pad 30 on surface, the first gasket 40 being arranged in the first tooth profile metal pad toothed surface and setting exist
Second tooth profile metal pads the second gasket 50 in toothed surface.
First tooth profile metal pad 20 and the second tooth profile metal pad 30 are fixed on insulation spacer 10 by way of bonding, the
One gasket 40 is fixed on the first tooth profile metal pad 20 by way of bonding, and the second gasket 50 is consolidated by way of bonding
It is scheduled on the second tooth profile metal pad 30, certainly, in addition to the connection type using bonding can also use other connection types, herein
It is not added and repeats.
Insulation spacer 10 is made of clamping cloth phenolic resin or glass fiber reinforced epoxy resin material, 20 He of the first tooth profile metal pad
Second tooth profile metal pad 30 is made of stainless steel material, and the one side that the first tooth profile metal pad 20 is contacted with insulation spacer 10 is light
Sliding surface, another side are toothed surface；The one side that second tooth profile metal pad 30 is contacted with insulation spacer 10 is shiny surface, and another side is tooth
Shape face；Insulation spacer 10 and the first tooth profile metal pad 20, the second tooth profile metal pad 30 are binded without the one side of sawtooth, make the first gold medal
Category dentiform gasket 20, the second tooth profile metal pad 30 will not fall off, and provide for the first tooth profile metal pad 20, the second tooth profile metal pad 30
Good insulation performance.
First gasket 40 and the second gasket 50 are made of rubber or polytetrafluoroethylene material.
After the utility model the first gasket 40 and the second gasket 50 are pressurized, the first tooth profile metal pad can be filled up
20, the gap between the second tooth profile metal pad 30 and flange sealing surface, generates good sealing, so that tooth form insulating gasket needed
Bolt torque is smaller than general dentiform gasket.
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
Claimed range is defined by the appending claims and its equivalent thereof.
