Abstract
The utility model discloses a kind of spirotallic gasket, include interior reinforcing ring, non-metallic, metal tape and outer annular-stiffer successively from inside to outside, the metal tape alternates overlapping with non-metallic, the metal tape is formed with non-metallic by the way of spiral winding compacting, and the beginning of the metal tape and non-metallic, last both ends are fixed using spot welding mode.The metal tape is mild steel metal tape.The utility model is using non-metallic and metal tape be overlapped, spiral winding is suppressed and formed, good seal performance.The inside and outside reinforcing ring that the utility model uses improves the screen resilience of pad, ensure that enough intensity, extends service life length.
Description
Technical field
Gasket seal technical field is the utility model is related to, is on a kind of spirotallic gasket more particularly.
Background technology
Spirotallic gasket is applied to that load is uneven, engaging force easily relaxes, and temperature and pressure cycle change, has impact or shake
Dynamic occasion.Spirotallic gasket is the preferable static seal original paper of the flange connections such as valve, pump, heat exchanger, tower, manhole, hand hole.
In chemical industry, pharmaceutical industries, the decoction in production process is conveyed by pipeline splicing, the pipeline of splicing it
Between sealing function ensured by spirotallic gasket.
Spirotallic gasket is by being located at the support ring of inner ring, the central filler of the locating ring of outer ring and winding filling between
Sealing structure is formed.Support ring and locating ring are usually arranged as metal material, and middle filling sealing structure is according to use environment
Difference graphite or polytetrafluoroethylene (PTFE) can be used.Existing spirotallic gasket when in use, works as gasket compression, in additional bolt lotus
When carrying overload, the problem of easily by conquassation, existence and stability is poor, is easily damaged, and service life is short, is, it is necessary to often change, so
Not only waste of manpower, material resources, it also have impact on the normal operation of production.
Therefore, how to ensure the stability and intensity of winding sealing gasket, while improve service life, be current this area skill
Art personnel's urgent problem to be solved.
The content of the invention
Goal of the invention：In view of the shortcomings of the prior art, applicant improves by repeatedly practice, devises a kind of wound gasket
Piece, the screen resilience of pad is improved, add pad to temperature, the adaptability of pressure change, while there is enough intensity.
Technical scheme：In order to realize foregoing invention purpose, technical scheme is used by the utility model：A kind of wound gasket
Piece, include interior reinforcing ring, non-metallic, metal tape and outer annular-stiffer, the metal tape and non-metallic phase successively from inside to outside
Mutually alternately stacked, the metal tape and non-metallic are formed by the way of spiral winding is suppressed, the metal tape with it is nonmetallic
The beginning of band, last both ends are fixed using spot welding mode.The metal tape is mild steel metal tape, and the thickness of the metal tape is
0.18mm。
Further, the non-metallic is any in asbestos yarn, flexible graphite belt, teflin tape, ceramic band
One kind, the thickness range of the non-metallic is 0.3~1.0mm.
The outer annular-stiffer is carbon steel ring, and the carbon steel ring surface sets one layer of antirust coat.
Beneficial effect：Compared with prior art, its advantage is the utility model：
1st, the utility model is using non-metallic and metal tape be overlapped, spiral winding is suppressed and formed, good seal performance.
2nd, the inside and outside reinforcing ring that the utility model uses improves the screen resilience of pad, ensure that enough intensity, extends
Service life length.
3rd, the utility model is simple in construction, is easy to produce and process.
Brief description of the drawings
Fig. 1 is a kind of structural representation of spirotallic gasket.
Embodiment
Below by a most preferred embodiment, the technical program is described in detail, but protection of the present utility model
Scope is not limited to the embodiment.
As shown in figure 1, a kind of spirotallic gasket, include successively from inside to outside interior reinforcing ring 1, non-metallic 2, metal tape 3 and
Outer annular-stiffer 4, the metal tape 3 alternate overlapping with non-metallic 2, and the metal tape 3 and non-metallic 2 are twined using spiral
Mode around compacting is formed, and the beginning of the metal tape 3 and non-metallic 2, last both ends are fixed using spot welding mode.The metal tape
3 be mild steel metal tape, and the thickness of the metal tape 3 is 0.18mm.
The non-metallic 2 is any one in asbestos yarn, flexible graphite belt, teflin tape, ceramic band, described
The thickness range of non-metallic 2 is 0.3~1.0mm.
The outer annular-stiffer 4 is carbon steel ring, and the carbon steel ring surface sets one layer of antirust coat.
Described above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
