Fig. 1 is the structural representation of spirotallic gasket provided by the invention.
Embodiment
The invention discloses a kind of spirotallic gasket, guaranteed to twine the high temperature requirement of sealing gasket, improve its property easy to clean simultaneously.
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technological scheme in the embodiment of the invention is carried out clear, complete description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiments.Based on embodiments of the invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment who obtains under the creative work prerequisite.
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, comprise inner ring support ring 1, outer ring positioning ring 2 and be arranged on sealing layer between the two, sealing layer comprises the stacked multi-layer sealing structure that is arranged between support ring 1 and the positioning ring 2, comprises near the teflon seal layer 3 of inner ring and the graphite grazing layer 4 of close outer ring.Utilize teflon seal layer 3 to have the characteristics of good resistance to acids and bases, after the medium-term and long-term use of the pipeline of soups such as chemical industry, pharmacy, be easy to the cleaning to delivery line, be arranged on internal layer, guaranteed the safety of delivery line herb liquid.Simultaneously, utilize graphite grazing layer 4 resistant to elevated temperatures characteristic, it is arranged on the outside of graphite grazing layer, make that the spirotallic gasket heat resistance on the whole after the preparation improves, when guaranteeing acid-proof alkaline, guaranteed the property easy to clean in the delivery line.
In the present invention's one specific embodiment, sealing layer is two-layer sealing configuration, comprises the teflon seal layer 3 of inner ring and the graphite grazing layer 4 of outer ring.Soup in internal layer polytetrafluoroethylene floor 3 and the delivery line contact, the good temperature capacity of outer field graphite grazing layer 4 assurance spirotallic gasket.
Particularly, teflon seal layer 3 is for twining the multi-layer structure that is arranged on the support ring outer ring.In the delivery line of chemical industry, pharmacy, there is certain discharge pressure in soup, spirotallic gasket is arranged between the link position of pipeline, also extruded by height by the end face of spirotallic gasket and delivery line for fear of soup, sealing layer is set for twining the multi-layer structure that arranges, each circle sealing configuration by the winding of sealing layer all plays sealing function, in its sealability of radially raising of spirotallic gasket.
Particularly, graphite grazing layer 4 comprises the multi-layer structure that twines setting.Graphite grazing layer 4 is by the structure that is prepared into multi-lay winding of technology of compacting, closely contact between each layer, and play sealing effect by the graphite structure of multilayer, guaranteed between the delivery line sealing effect,
In the present invention's one specific embodiment, support ring 1 has the boss supporting structure along its cross section radially; The cross section of positioning ring 2 is set to seal the locking groove structure that compresses with the boss supporting structure of support ring 1.Spirotallic gasket is the annular flake structure, after the spirotallic gasket of multi-layer structure is set, its still easily transport and loading process in be subjected to axial bending power and produce the phenomenon of mutual dislocation between the sealing layer, undertaken spacing by the sealing layer that support ring 1 and 2 pairs of inside of positioning ring are set, can improve the non-deformability of spirotallic gasket to a certain extent, however the still situation generation of mutual dislocation between the inevitable sealing configuration.
By offering boss supporting structure radially and lock groove structure at support ring 1 and positioning ring 2, make sealing layer in winding process, each layer all can carry out fastening by groove structure, the last positioning ring 2 that all sealing layers are locked that arranges in the outer ring of spirotallic gasket, make closely to contact between each layer sealing layer, thus the stability of raising spirotallic gasket self form.
Particularly, the cross section of support ring 1 is V-arrangement boss supporting structure.Spirotallic gasket in use is arranged between two pipelines of splicing, and V-arrangement boss supporting structure is set, and the sealability of the spirotallic gasket both sides after the preparation is suitable, and applicability is strong, can play the better seal effect.
Preferably, the bottom of V-arrangement boss supporting structure is away from the center of support ring.Then in the compacted process of the sealing material of spirotallic gasket, each layer sealing material all contacts with the junction surface of pipeline closely, and sealing material stop direction towards the inside of delivery line, improve sealability.
In the present invention's one specific embodiment, the graphite grazing layer 4 of multi-layer structure is the graphite grazing layer 4 that is twined compacting by single carbon shoe.Spirotallic gasket is for having certain thickness thin plate member, and graphite grazing layer 4 radially has certain thickness along it, in order to reduce the difficulty of processing in the spirotallic gasket preparation process, adopt the mode of compacting to prepare on graphite grazing layer 4, namely at first prepare the Stamping Steel Ribbon of single graphite material, be wound on the supporting structure by compressing of from coil to coil then, by the mode of twining, guarantee the sealing effect of preparation back spirotallic gasket, simplified preparation process.
In the present invention's one specific embodiment, also be provided with supporting band 5 between teflon seal layer 3 and the graphite grazing layer 4.Setting has the spirotallic gasket of double-layer seal material, because two kinds of sealing materials have different material behaviors at link position, all bring into play the performance of himself effectively for guaranteeing every kind of material, supporting band is set, when respectively teflon seal layer and graphite grazing layer being played support function, guarantee the sealing effect of each sealing layer material.
Preferably, supporting band 5 is for twining the support steel band that is arranged on the polytetrafluoroethylene floor outer shroud.
Each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed is and other embodiments' difference that identical similar part is mutually referring to getting final product between each embodiment.
To the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the present invention.Multiple modification to these embodiments will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments herein.Therefore, the present invention will can not be restricted to these embodiments shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
