Description
Technical field
This utility model is related to encapsulant technical field, more particularly to a kind of compound wound gasket.
Background technology
In chemical industry, pharmaceutical industries, the medicinal liquid during production is conveyed by pipeline splicing, the pipeline of splicing it
Between sealing function is ensured by spirotallic gasket.
Spirotallic gasket is by being located at the support ring of inner ring, the locating ring of outer ring and winding filling central filler between
Sealing structure is constituted.Support ring and locating ring are usually arranged as metal material, and middle filling sealing structure is according to use environment
Difference can use graphite or politef.
Graphite-filled winding sealing gasket, due to the resistant to elevated temperatures feature of graphite, can be applicable to the ring of maximum temperature to 550 degree
Border, however, the acid-alkali-resistant degree of graphite is low, easily dissolves during life-time service, causes to convey the pollution of medicinal liquid so that production
Environment is dirtier, is unfavorable for the transport of medicinal liquid.Using the winding sealing gasket of politef, which has stronger resistance to acids and bases, clearly
Clean property is good, but the heat-resisting ability of the spirotallic gasket of politef material is weak, can be only applied to the environment within 280 degree,
It is not suitable for the application of chemical industry and pharmaceutical industry.
Therefore, how to ensure to wind the high temperature requirement of sealing gasket, while improving its property easy to clean, be current art technology
Personnel's problem demanding prompt solution.
The content of the invention
Technical problem to be solved in the utility model is provided one kind and is ensureing to twine for above-mentioned state of the art
Around the high temperature requirement of sealing gasket, while the compound wound gasket of its property easy to clean can also be improved.
This utility model solve the technical scheme that adopted of above-mentioned technical problem for：The compound wound gasket, including inner ring
Support ring, the locating ring of outer ring and the sealant being disposed there between, it is characterised in that：If the sealant includes dried layer
Metal tape and inserts band that alternately winding is arranged, the inserts band include being stacked the graphite encapsulation layer near inner ring
And near the Muscovitum and/or fiberglass sealed layer of outer ring, and the support ring of the inner ring, the locating ring of outer ring and be arranged on
The upper surface and/or lower surface of sealant therebetween is coated with soft graphite layer.
Further, the metal tape includes V-type supporting steel band, and the V-type supporting steel band is set to many V-types in broadband,
The angle [alpha] of the V-type is 80～85 °.It is close between the compound support ring of wound gasket inner ring and the locating ring of outer ring due to being arranged on
The V-type supporting steel band of sealing is set to 80～85 ° by angle, empty so as to increased extension of the supporting steel band in pressurized process
Between, pressurized stroke is increased, is prevented supporting steel band from easily falling apart under impact, pressure vibration and is played better seal effect, together
When V-type supporting steel band be set to many V-types in broadband, that is, have adjusted the thickness and width of supporting steel band, supporting steel band can be greatly improved
Bearing capacity, non-deformability and supporting area.
Further, every slice width degree of described V-type supporting steel band is 1.5mm～2mm.Adjust in the broadband of V-type supporting steel band
Section, can greatly improve the bearing capacity and non-deformability of supporting steel band.
Preferably, the angle [alpha] of described V-type is 80 °.
Compared with prior art, the utility model has the advantage of compound wound gasket using near outer ring Muscovitum and/
Or fiberglass sealed layer and the graphite encapsulation layer near inner ring, Muscovitum and glass fibre are high-temperature material, can tolerate high temperature,
Meanwhile, using the resistant to elevated temperatures feature of graphite encapsulation layer, it is disposed near inner ring so that the spirotallic gasket after preparation is ensureing
Thermostability also assures that property easy to clean while raising, and the support ring of inner ring, the locating ring of outer ring and be disposed there between
Sealant upper surface and/or lower surface be all covered with soft graphite layer, the soft graphite layer should be with upper lower flange
Sealing surface is contacted well, and produces good sealing effectiveness.
Description of the drawings
Structural representations of the Fig. 1 for this utility model embodiment；
Fig. 2 is the I magnified partial views in Fig. 1；
Fig. 3 is the structural representation of V-type supporting steel band in this utility model embodiment.
Specific embodiment
This utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Figures 1 to 3, this compound wound gasket includes the locating ring 2 of the support ring 1, outer ring of inner ring and is arranged on two
Sealant between person, if sealant includes the dried layer metal tape that alternately winding is arranged and inserts band, inserts band includes layer
The folded graphite encapsulation layer 3 for being positioned close to inner ring and the Muscovitum and/or fiberglass sealed layer 4 near outer ring, metal tape are arranged
Between the inserts band of arbitrary adjacent two layers, and the locating ring 2 of the support ring 1, outer ring of inner ring and it is disposed there between
The upper and lower surface of sealant is all covered with soft graphite layer 5.In the present embodiment, metal tape is set to wind many of setting
Slice width band V-structure, is 1.5mm～2mm per slice width degree, while V-type supporting steel is set to into 80 ° with 6 V-type angle also, from
And extension space of the supporting steel band in pressurized process is increased, pressurized stroke is increased, and supporting steel band is prevented in impact, pressure
Easily fall apart under vibration so that spirotallic gasket plays better seal effect.
In the present embodiment, near the Muscovitum and/or fiberglass sealed layer 4 and the graphite encapsulation layer 3 near inner ring of outer ring,
Muscovitum and glass fibre are high-temperature material, can tolerate high temperature, meanwhile, using 3 resistant to elevated temperatures feature of graphite encapsulation layer, set
