Abstract
The utility model relates to a high-pressure graphite metal gasket with edges wrapped internally and externally. The graphite metal gasket with the edges wrapped internally and externally comprises an annular metal framework. The upper surface and the lower surface of the annular metal framework are provided with a plurality of concentrically ringed annular grooves. The upper surface and the lower surface of the annular metal framework are combined with expanded graphite. The inner edge and the outer edge of the annular metal framework are provided with covered edges. The high-pressure graphite metal gasket is good in sealing effect, can be used under the environments with various corrosive chemical medicine fluids such as strong base, muriatic acid, vitriol and strong corrosive fluid, organic solvent and liquid nitrogen, and can be widely used for sealing flanges, valves, reaction kettles, pumps, pressure containers, heat exchangers, condensers, generators, air compressors, exhaust pipes and other devices used in industries such as petroleum, chemical engineering, chemical fiber, cola mining, electricity generating and metallurgy.
Description
Technical field
The utility model relates to a kind of seal arrangement, is specifically related to a kind of inside and outside bound edge high-pressure graphite metal gasket.
Background technique
Before the utility model is made, metal frame thickness in the middle of the graphite composite pad was generally between 0.1-0.2mm in the past, within working pressure was only limited to 15Mpa, common profile of tooth, ripple tooth pad there is no up and down composite material and without inside and outside bound edge, sealing effect is had a greatly reduced quality.
The model utility content
The purpose of this utility model is to provide a kind of inside and outside bound edge high-pressure graphite metal gasket, good sealing effect, can be at various aggressive chemistry medicine fluid highly basic, hydrochloric acid, use under the environment such as the strongly corrosion liquids such as sulfuric acid, organic solvent, liquid nitrogen, can be widely used in the sealing of the industry equipments such as oil, chemical industry, chemical fibre, coal mining, generating, metallurgy flange used, valve, reactor, pump, pressurized container, heat exchanger, condenser, generator, air compressor, outlet pipe, refrigerator etc.
In order to achieve the above object, the utility model has following technological scheme:
A kind of inside and outside bound edge high-pressure graphite metal gasket of the present utility model, comprise the endless metal skeleton, the upper surface of described endless metal skeleton, lower surface are provided with several concentrically ringed annular grooves, upper surface, lower surface at the endless metal skeleton are compounded with expanded graphite, are equipped with bound edge at inward flange and the outward edge of endless metal skeleton.
Wherein, the thickness of described endless metal skeleton is 2-3mm, and described bound edge is metallic material.
Owing to having taked above technological scheme, the utility model has the advantage of:
1, realize sealing at upper surface, the lower surface of endless metal skeleton compound expanded graphite and flange facing close contact.
2, the upper surface of endless metal skeleton, lower surface are provided with several concentrically ringed annular grooves and have the rebound elasticity of a bit, make sealing effect better.
3, inward flange and the outward edge at the endless metal skeleton is equipped with bound edge, can further reach the effect of sealing.
4, the utility model can adapt to various aggressive chemistry medicine fluid highly basic, hydrochloric acid, the environment such as the strongly corrosion liquids such as sulfuric acid, organic solvent, liquid nitrogen.
5, the utility model can be widely used in the sealing of the industry equipments such as oil, chemical industry, chemical fibre, coal mining, generating, metallurgy flange used, valve, reactor, pump, pressurized container, heat exchanger, condenser, generator, air compressor, outlet pipe, refrigerator etc.
Description of drawings
Fig. 1 is the integrally-built schematic diagram of the utility model.
Fig. 2 be Fig. 1 A-A to the schematic diagram of sectional view.
In figure: 1, bound edge; 2, expanded graphite; 3, endless metal skeleton.
Embodiment
Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
Referring to Fig. 1-2, a kind of inside and outside bound edge high-pressure graphite metal gasket of the present utility model, comprise the endless metal skeleton, the upper surface of described endless metal skeleton, lower surface are provided with several concentrically ringed annular grooves, upper surface, lower surface at the endless metal skeleton are compounded with expanded graphite, are equipped with bound edge at inward flange and the outward edge of endless metal skeleton.
The thickness of described endless metal skeleton is 2-3mm, and described bound edge is metallic material.
The utility model is under certain preload pressure, and expanded graphite and flange facing close contact are realized sealing; The rebound elasticity that is had any by the endless metal skeleton, flexible expanded graphite is lined with extraordinary sealing effect through the bulk metal of inside and outside bound edge again as sealing surface.
Obviously, above-mentioned enforcement of the present utility model is only for the utility model example clearly is described, and is not to be restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give all mode of executions exhaustive.Everyly belong to the row that apparent variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
Claims (2)
1. bound edge high-pressure graphite metal gasket inside and outside a kind, comprise the endless metal skeleton, it is characterized in that: the upper surface of described endless metal skeleton, lower surface are provided with several concentrically ringed annular grooves, upper surface, lower surface at the endless metal skeleton are compounded with expanded graphite, are equipped with bound edge at inward flange and the outward edge of endless metal skeleton.
