Abstract
A kind of metal jacketed gasket, belong to sealing element technical field, it includes the annular soft pad piece being made of nonmetallic materials such as soft graphite, asbestos packing sheet, ceramic fibres, and it is coated on the sheet metal outside the cushion film, sheet metal includes the identical upper metallic cover piece of size and lower metallic cover piece, and metallic cover piece covers the whole surface up and down of cushion film and partial interior lateral surface.The both ends of covering piece are connected in side by elastic component, and covering piece the region not covered just to be covered by elastic component.The ingenious connection of covering piece and elastic component makes gasket have own resilience, solves conventional metals cladding gasket rebound force difference, the problem more demanding to flange fastening force.Good airproof performance, it is simple in structure, it is readily produced, can play a key effect in field of sealing technology afterwards.
Description
Technical field
The utility model is related to a kind of gasket seal, more particularly to a kind of good airproof performance, the metal with good screen resilience
Coat gasket.
Background technology
Metal jacketed gasket means inside nonmetallic materials (soft graphite, asbestos packing sheet, ceramic fibre）Deng external
The composite gasket that sheet metal is coated with specific cold process is generally divided into plane cladding and ripple type by gasket section
Two kinds of cladding is a kind of most traditional gasket, is suitable for heat exchanger, pressure vessel, pump, valve and flange face sealing.
Metal jacketed gasket advantage is that intensity is big, non-friable, securely solid, but screen resilience is limited, needs to seek flange surface
Flat and fastening force is very high to can be only achieved good result.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, adapt to reality and need, design a kind of good airproof performance,
There is the SW with outside ring of good screen resilience.
In order to realize that the utility model aim, the utility model use following technical solution：
A kind of metal jacketed gasket is designed, it includes by nonmetallic materials such as soft graphite, asbestos packing sheet, ceramic fibres
The annular soft pad piece of composition, and it is coated on the sheet metal outside the cushion film, sheet metal includes on size is identical
Covering piece and lower covering piece, metallic cover piece cover the whole surface up and down of cushion film and partial interior lateral surface.Covering piece
Both ends are connected in side by elastic component, and covering piece the region not covered just to be covered by elastic component.Covering piece and elastic component
Ingenious connection forms complete cladding to internal cushion film.
Preferably, metallic cover thin slice is connected in side by elastic component,
Further, covering piece and elastic component form complete cladding to cushion film.
The advantageous effect of this reality utility model is：It solves conventional metals cladding gasket rebound force difference, flange is fastened
The more demanding problem of power, simple in structure, easy to produce, good airproof performance.
Description of the drawings
Fig. 1 is the vertical view of gasket；
Fig. 2 is the sectional view of gasket；
Fig. 3 is the section partial enlarged view of gasket；
Metallic cover piece, 2 nonmetallic cushion films, 3 elastic components, 4 times metallic cover pieces on 1 in figure.
Specific implementation mode
The utility model is described in detail below in conjunction with the accompanying drawings：
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and specifically
The technical solution of the utility model embodiment is clearly and completely described in embodiment.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments.Based on described the embodiments of the present invention, originally
The every other embodiment that field technology personnel are obtained shall fall within the protection scope of the present invention.
Referring to Fig.1, Fig. 2, Fig. 3, the utility model are a kind of metal jacketed gasket, including by soft graphite, asbestos rubber
The cushion film that the nonmetallic materials such as plate, ceramic fibre are constituted（2）, and it is coated on cushion film（2）External sheet metal, metal
Thin slice includes the identical upper metallic cover piece of size（1）With lower metallic cover piece（4）, metallic cover piece cover cushion film up and down
Whole surface and partial interior lateral surface.The both ends of covering piece pass through elastic component in side（3）Connection, covering piece the area not covered
Domain is just by elastic component（3）Covering.Covering piece and elastic component（3）Ingenious connection complete cladding is formed to internal cushion film.
In real work, when flange external pressure is excessive, gasket is compacted, and elastic component is compressed, and two covering pieces work as pressure apart from close
Power becomes hour, and inner non-metallic layer starts to spring back, and then elastic component is and then sprung back, and two covering pieces return to initial position.In pressure
Gasket is sprung back by the performance itself of elastic component during alternation, prevents from damaging because metal is different with nonmetallic elastic property
Hinder gasket.In addition metallic cover piece and elastic component also can prevent Korrosionsmedium to internal cushion the protection of internal non-metallic layer
The corrosion of piece, increases service life, is always maintained at good leakproofness.
In summary：The utility model adds elastic component, passes through metal on the basis of conventional metals treasured coats gasket
The ingenious connection of covering piece and elastic component not only can guarantee the integrality of cladding but also gasket can be made to have good resilience, solved
Conventional spacers conventional metals cladding gasket springs back force differences, the problem more demanding to flange fastening force.
Above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple
Other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope should all cover in the right of the utility model.
