In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of spirotallic gasket provided by the invention.
Embodiment
The invention discloses a kind of spirotallic gasket, ensure that the high temperature requirement being wound around sealing gasket, improve its property easy to clean simultaneously.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, carry out clear, complete description to the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on embodiments of the invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, Fig. 1 is the structural representation of spirotallic gasket provided by the invention.
The invention provides a kind of spirotallic gasket, the sealing layer comprising the support ring 1 of inner ring, the positioning ring 2 of outer ring and be arranged on therebetween, sealing layer comprises the stacked multi-layer sealing structure be arranged between support ring 1 and positioning ring 2, comprises the teflon seal layer 3 near inner ring and the graphite encapsulation layer 4 near outer ring.Utilize teflon seal layer 3 to have the feature of good resistance to acids and bases, in the pipeline of the liquid such as chemical industry, pharmacy after long-term use, be easy to, to the cleaning of delivery line, be arranged on internal layer, ensure that the safety of delivery line herb liquid.Meanwhile, utilize the resistant to elevated temperatures feature of graphite encapsulation layer 4, be arranged on the outside of graphite encapsulation layer, the heat resistance on the whole of the spirotallic gasket after preparing is improved, while guarantee acid-proof alkaline, ensure that the property easy to clean in delivery line.
In the present invention one specific embodiment, sealing layer is two-layer sealing configuration, comprises the teflon seal layer 3 of inner ring and the graphite encapsulation layer 4 of outer ring.Internal layer polytetrafluoroethylene floor 3 contacts with the liquid in delivery line, and outer field graphite encapsulation layer 4 ensures the temperature capacity that spirotallic gasket is good.
Particularly, teflon seal layer 3 is be wound around the multi-layer structure be arranged on support ring outer ring.In the delivery line of chemical industry, pharmacy, there is certain discharge pressure in liquid, spirotallic gasket is arranged between the link position of pipeline, in order to avoid the end face of liquid by spirotallic gasket and delivery line is also extruded by height, arranging sealing layer is be wound around the multi-layer structure arranged, all play sealing function by each circle sealing configuration of the winding of sealing layer, improve its sealability in the radial direction of spirotallic gasket.
Particularly, graphite encapsulation layer 4 comprises the multi-layer structure being wound around and arranging.Graphite encapsulation layer 4 by the structure being prepared into multi-lay winding of the technique of compacting, close contact between every one deck, and play sealing effect by the graphite structure of multilayer, ensure that the sealing effect between delivery line,
In the present invention one specific embodiment, support ring 1 cross section radially has boss supporting structure; The cross section of positioning ring 2 is set to seal with the boss supporting structure of support ring 1 the locking groove structure compressed.Spirotallic gasket is annular flake structure, after the spirotallic gasket of multi-layer structure is set, it is the easy phenomenon producing mutual dislocation between sealing layer transporting and be subject to axial folding force in loading process still, by arranging support ring 1 and positioning ring 2 carries out spacing to the sealing layer of inside, the non-deformability of spirotallic gasket can be improved to a certain extent, however still between inevitable sealing configuration the situation of mutual dislocation produce.
By offering boss supporting structure radially and locking groove structure on support ring 1 and positioning ring 2, make sealing layer in winding process, every one deck all carries out fastening by groove structure, finally the positioning ring 2 of locking all sealing layers is set in the outer ring of spirotallic gasket, make close contact between every one deck sealing layer, thus improve the stability of spirotallic gasket its own shape.
Particularly, the cross section of support ring 1 is V-arrangement boss supporting structure.Spirotallic gasket is in use arranged between two pipelines of splicing, arranges V-arrangement boss supporting structure, and the sealability of the spirotallic gasket both sides after preparation is suitable, and applicability is strong, can play good sealing effect.
Preferably, the bottom of V-arrangement boss supporting structure is away from support Ring current distribution.In the process that then sealing material of spirotallic gasket is compacted, every one deck sealing material contacts with the junction surface of pipeline all closely, and the stop direction of sealing material is towards the inside of delivery line, improves sealability.
In the present invention one specific embodiment, the graphite encapsulation layer 4 of multi-layer structure is the graphite encapsulation layer 4 being wound around compacting by single carbon shoe.Spirotallic gasket is for having certain thickness thin plate component, and graphite encapsulation layer 4 radially has certain thickness, in order to reduce the difficulty of processing in spirotallic gasket preparation process, the mode of compacting is adopted to prepare graphite encapsulation layer 4, namely first prepare the Stamping Steel Ribbon of single graphite material, be then wound in supporting structure by the compression of from coil to coil, by the mode be wound around, ensure the sealing effect of the rear spirotallic gasket of preparation, simplify preparation process.
In the present invention one specific embodiment, between teflon seal layer 3 and graphite encapsulation layer 4, be also provided with supporting band 5.The spirotallic gasket with double-layer seal material is set, because two kinds of sealing materials have different material behaviors at link position, for ensureing that often kind of material plays the performance of himself all effectively, supporting band is set, while respectively support function being played to teflon seal layer and graphite encapsulation layer, ensure the sealing effect of each sealing layer material.
Preferably, supporting band 5 is be wound around the support steel band be arranged on polytetrafluoroethylene floor outer shroud.
In this specification, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
