Description
Technical field
The utility model is related to seal technical field, specifically composite sealing pad.
Background technology
In the industrial equipment such as pipeline, valve, pump and pressure vessel, heat exchanger, condenser or spare part, often use
Potted component, pad is exactly most wide, the most commonly seen part of the scope of application in potted component.
The sealing of the said equipment can be not only kept using pad, while the wear problem mouthful of connector can also be solved
The species of pad is varied, is divided into nonmetallic, semimetal and metallic gasket three major types by the material of main part of its construction, wherein non-
Metallic gasket soft texture, corrosion-resistant, price are also relatively cheap, therefore application is more wide, are common in normal temperature and middle temperature
Container or pipeline flange seal.
In original non-metallic gasket, asbestos pad based on asbestos material and main body is mixed into asbestos rubber material
Asbestos rubber pad using more, asbestos material has good temperature-resistance thermal-insulation and sealing property, but is due to asbestos material bag
Containing superfine fiber, when these tiny fibers are inhaled into human body, it will adhere to and be deposited on lung, cause lung's disease
Disease, such as:Knurl between the skin of asbestosis, pleura and peritonaeum, causes lung cancer when serious, the health to setter causes serious injury, state
Family, which has prohibited, to be used.
In the prior art, the pad of other fibrous material roll-formings, the vertical transverse strength of its own is not enough, and big portion
Divide and come from import, not only permeability or slip are relatively low, and performance is preferable not to the utmost, and cost is higher.
Utility model content
The utility model is for deficiency of the prior art there is provided composite sealing pad, and it passes through metallic framework, metal
The cooperation of silk screen and graphite linings, with oil resistant, high temperature resistant, low slip, vertical transverse strength are good, use face pressure to require smaller model
The performance such as big is enclosed, manufacturing is stronger, widely applicable, meet the characteristics such as environmental requirement.
In order to solve the above technical problems, the utility model is addressed by following technical proposals：Composite sealing pad, bag
Metallic framework, graphite composite parts and graphite linings are included, the metallic framework is bonded by two groups of sheet metals and formed, the metal bone
Frame is coated on interior and forms three cavity bodies by the graphite linings, is each filled with the cavity body and contains metallic particles
Graphite composite parts, meanwhile, the surface that the graphite linings are contacted is provided with tack coat in the metallic framework.
In above-mentioned technical proposal, it is preferred that it is oblique that the sheet metal includes long metal bar, short metal bar and metal
Bar, the two ends of the metal brace are connected with the long metal bar and the short metal bar respectively.
The beneficial effects of the utility model are：The utility model passes through metallic framework, graphite composite parts and graphite linings
Coordinate, with oil resistant, high temperature resistant, low slip, vertical transverse strength are good, smaller range is required using the face pressure performance, manufacture such as big
Property is stronger, widely applicable, meet the characteristics such as environmental requirement.
Brief description of the drawings
Fig. 1 is the utility model schematic cross-section.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：Referring to Fig. 1, it is combined close
Gasket, including metallic framework 1, graphite composite parts 2 and graphite linings 3.
Wherein, the metallic framework is bonded by two groups of sheet metals and formed, the sheet metal include long metal bar 11,
Short metal bar 12 and metal brace 13, the two ends of the metal brace 13 respectively with the long metal bar 11 and described
After short metal bar 12 is connected, and two pieces of sheet metals are combined so that long metal bar and short metal bar are in angular distribution
The metallic framework that triangle is set can lift steadiness, have good support effect to the graphite linings of periphery.
Wherein, the metallic framework 1 is coated on interior and forms three cavity bodies 4 by the graphite linings 3, each the cavity
It is filled with the graphite composite parts 2 containing metallic particles in body 4, graphite composite parts 2 and the corresponding face of metallic framework 1 and corresponding
The laminating of the face of graphite linings 3, graphite composite parts be graphite and metallic particles it is compound after the composite members that are formed.
Wherein, the surface that the graphite linings 3 are contacted is provided with tack coat 5 in the metallic framework 1.
By test, the performance indications of the utility model product are：Oil resistivity：In No.3 oil, 150 DEG C, 5Hr thickens rate
For≤+ 10%, rate of body weight gain is≤+ 25%；Fuel B, RT-5hr, the rate that thickens are≤+ 6%, and rate of body weight gain is≤+ 30%；High temperature resistant：Can
With to 600 DEG C；Low slip：Can be to 1.0 ~ mg/m/s；Use face pressure：1.5~120Mpa.
It is worth noting that, above according to embodiment shown in the drawings, structure of the present utility model, feature is described in detail
And operation principle, those skilled in the art can be carried out in the range of without departing from main idea of the present utility model it is various change knot
Close and implement, therefore, every utilization and the same or similar technical scheme of the utility model, as long as without departing from the utility model
Various equivalent change embodiments in scope, should all be covered by within protection category of the present utility model.
