Abstract
The invention discloses a kind of teflon gasket.It includes the rubber bodies of loop configuration, multi-turn raised item is placed with from inside to outside on the both sides end face of the rubber bodies, the height of each circle raised item gradually increases from inside to outside, there is the polytetrafluoroethylmaterial material layer from rubber bodies annular center hole to outer cladding, the thickness of polytetrafluoroethylmaterial material layer is 2 3mm on the both sides end face of rubber bodies.After above-mentioned structure, its dexterously structure design, sealed extruded can be carried out using the elasticity of raised item in seal process, the raised item of different height is layering sealing, enhances sealing property, sealing is tight reliable, in addition, polytetrafluoroethylmaterial material layer and carbon fiber layer can not only improve wearability, and also advantageously improve corrosivity, its service life is extended, ensure that the reliability used.
Description
Technical field
The present invention relates to a kind of gasket seal, specifically a kind of teflon gasket.
Background technology
Sealing gasket be in the industries such as oil, chemical industry, machinery, generating in order to realize sealing possessed by one it is essential
Part, although its structure very simple, but there is protrusion in various occasions, existing rubber cushion is tied due to it
Structure design is unreasonable, on the one hand, so that corrosion resistance ability is poor, service life is very short；Still further aspect, easily abrasion and
There is a situation where poorly sealed, reduce the reliability used.
The content of the invention
The technical problem to be solved in the present invention is to provide one kind, not only resistance to corrosion is strong, and good sealing effect, uses
The high teflon gasket of reliability.
In order to solve the above-mentioned technical problem, teflon gasket of the invention, the rubber bodies of loop configuration are included, it is described
Multi-turn raised item is placed with from inside to outside on the both sides end face of rubber bodies, each height for enclosing raised item gradually increases from inside to outside,
There is the polytetrafluoroethylmaterial material layer from rubber bodies annular center hole to outer cladding, polytetrafluoroethylene (PTFE) on the both sides end face of rubber bodies
The thickness of material layer is 2-3mm.
The raised edge sealing of arc is provided between the inside edge of the rubber bodies and the most circle of inner side one raised item.
The raised edge sealing tilts extension from inside to outside.
Carbon fiber layer is additionally provided with outside the polytetrafluoroethylmaterial material layer.
After above-mentioned structure, due to rubber bodies of the setting with multi-turn raised item and from rubber bodies annular center
Polytetrafluoroethylmaterial material layer from hole to outer cladding and respectively enclose the height of the raised item and gradually increase from inside to outside, it is dexterously
Structure design, sealed extruded, the raised item layer stackup of different height can be carried out using the elasticity of raised item in seal process
Encryption envelope, sealing property is enhanced, sealing is tight reliable, in addition, polytetrafluoroethylmaterial material layer and carbon fiber layer can not only carry
High-wearing feature, and corrosivity is also advantageously improved, its service life is extended, ensure that the reliability used.
Brief description of the drawings
Fig. 1 is the structural representation of invention teflon gasket.
Embodiment
With reference to the accompanying drawings and detailed description, the teflon gasket of the present invention is described in further detail.
As illustrated, the teflon gasket of the present invention, include the rubber bodies 1 of loop configuration, the two of the rubber bodies 1
Multi-turn raised item 2 is placed with side end face from inside to outside, each height for enclosing raised item 2 gradually increases from inside to outside, rubber bodies 1
There is the polytetrafluoroethylmaterial material layer 3 from rubber bodies annular center hole to outer cladding, polytetrafluoroethylmaterial material layer 3 on the end face of both sides
Thickness be 2-3mm,
The structure design of its raised item 2 cause polytetrafluoroethylmaterial material layer 3 be coated on rubber bodies 1 it is outer when still formed projection knot
Structure, polytetrafluoroethylmaterial material layer 3 are additionally provided with carbon fiber layer outside.
Further, it is provided with the convex of arc between the inside edge of described rubber bodies 1 and the most circle of inner side one raised item 2
Edge sealing 4 is played, raised edge sealing 4 tilts extension from inside to outside, in addition, the height of the peak of raised edge sealing 4 is higher than the projection at middle part
The height of bar 2, thus with can by raised edge sealing 4 when usage time is long or polytetrafluoroethylmaterial material layer has damaged
Compensate sealing so that sealing reliability further improves.
