Description
Technical field：
It the utility model is related to sealing gasket technical field, and in particular to a kind of magnetic seal pad.
Background technology
Gasket seal, as long as it is that a kind of place for having fluid for machinery, equipment, pipeline is used with sealing spare part,
Using inside and outside, the material to seal.Gasket seal is with metal or nonmetallic tabular material, cleaved, punching press or sanction
The technique such as cut to be made, for the sealed connection between pipeline, the sealed connection between the parts and parts of machinery equipment.By material
Metallic packing and nonmetallic gasket seal can be divided into.Metal has copper backing, stainless steel gasket, iron gasket, aluminium backing etc..
Nonmetallic has asbestos washer, non-asbestos pad, paper gasket, rubber sheet gasket etc..
The existing gasket seal specification of in the market is relatively more unified, so for some more special places, can not use
The gasket seal of suitable thickness is sealed, according to multiple gasket seals words used at the same time, though the requirement of thickness is met,
But the connection between gasket seal is not but close, easily comes off, influences last use, so needing to existing sealing gasket
Piece carries out some improvement, and to adapt to actual needs, and the service life of existing gasket seal need to be improved.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of magnetic seal pad, and the magnetic efficiently solved is close
Gasket easily comes off mostly, short life, structural instability, connects untight phenomenon, there is provided and it is a kind of simple in construction, make
Cost is relatively low, and Stability Analysis of Structures is firm, and service life length, tight ness rating is high, and rigidity and intensity are good, and Sealing Stress is constant, good reliability
Magnetic seal pad.
To solve the above problems, the utility model adopts the following technical scheme that：A kind of magnetic seal pad, including sealing gasket
Piece body, it is characterised in that：Described gasket seal body is divided into external seal pad and interior sealing pad；The external seal pad
Metal copper sheet is provided between interior sealing pad, and magnetic iron ring is evenly distributed with metal copper sheet；The gasket seal sheet
The outside of body is coated with one layer of rubber membrane；The first sealing flange is provided between the external seal pad and metal copper sheet；It is described
Interior sealing pad and metal copper sheet between be provided with the second sealing flange.
Further, small projection of the same size is provided with the rubber membrane.
Further, it is embedded with stiffener ring in first sealing flange and the second sealing flange.
Further, the metal copper sheet and magnetic iron ring use integral structure.
Further, using asbestos fibre filling vacancy between the external seal pad and interior sealing pad.
A kind of effect of magnetic seal pad of the utility model is：When coming into operation, gasket seal body is divided into outer close
Gasket and interior sealing pad, stress can be increased, metal copper sheet can increase the hardness of structure to a certain extent, thereon
Magnetic iron ring can allow the tight ness rating of multiple gasket seals higher, can according to actual conditions, change thickness, rubber membrane and its
On small projection can increase frictional force, sealing property greatly increases, embedded in the first sealing flange and the second sealing flange
There is stiffener ring, so add the intensity of structure, so as to ensure that Sealing Stress is constant, increase its reliability, it is outer close
Between gasket and interior sealing pad using asbestos fibre filling vacancy can be more wear-resisting, its is simple in construction, cost of manufacture compared with
Low, Stability Analysis of Structures is firm, service life length, is connected using magnetic, can increase the tight ness rating between gasket seal, external seal pad
Piece and interior sealing pad remain enough rigidity and intensity, so as to ensure that Sealing Stress is constant, and then ensure that sealing gasket
The job stability of piece and the sealing reliability of sealing system.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of overlooking the structure diagram of magnetic seal pad of the utility model.
1- gasket seal bodies；2- magnetic iron rings；3- external seal pads；The sealing flanges of 4- first；5- stiffener rings；
6- asbestos fibres；7- metal copper sheets；The sealing flanges of 8- second；9- interior sealing pads.
Embodiment
Refering to a kind of magnetic seal pad shown in Fig. 1, including gasket seal body 1, it is characterised in that：Described sealing
Shim body 1 is divided for external seal pad 3 and interior sealing pad 9；It is provided between the external seal pad 3 and interior sealing pad 9
Metal copper sheet 7, and magnetic iron ring 2 is evenly distributed with metal copper sheet 7；The outside of the gasket seal body 1 is coated with one layer
Rubber membrane；The first sealing flange 4 is provided between the external seal pad 3 and metal copper sheet 7；Described interior sealing pad 9 with
The second sealing flange 8 is provided between metal copper sheet 7.
As preferable technical scheme, small projection of the same size is provided with the rubber membrane.
As preferable technical scheme, stiffener is embedded with the sealing flange 8 of the first sealing flange 4 and second
Ring 5.
As preferable technical scheme, the metal copper sheet 7 and magnetic iron ring 2 use integral structure.

Vacancy.
A kind of operation principle of magnetic seal pad of the utility model：When coming into operation, gasket seal body 1 divides to be outer
Gasket seal 3 and interior sealing pad 9, stress can be increased, metal copper sheet 7 can increase the hardness of structure to a certain extent,
Magnetic iron ring 2 thereon can allow the tight ness rating of multiple gasket seals higher, can change thickness, rubber according to actual conditions
Film and small projection thereon can increase frictional force, and sealing property greatly increases, the first sealing flange 4 and the second sealing flange
Stiffener ring 5 is embedded with 8, so adds the intensity of structure, so as to ensure that Sealing Stress is constant, increasing it can
By property, filling vacancy using asbestos fibre 6 between external seal pad 3 and interior sealing pad 9 can be more wear-resisting, the letter of its structure
Single, cost of manufacture is relatively low, and Stability Analysis of Structures is firm, service life length, is connected using magnetic, can increase tight between gasket seal
Density, external seal pad and interior sealing pad remain enough rigidity and intensity, so as to ensure that Sealing Stress is constant, and then
It ensure that the job stability of gasket seal and the sealing reliability of sealing system.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
