Abstract
The utility model relates to a composite sealing O-shaped ring, which combines the advantages of excellent elasticity of rubber and good corrosion resistance of polytetrafluoroethylene, and adopts the processing technology of a molding knife, wherein two polytetrafluoroethylene layers are coated on outside a basal rubber O-shaped ring, the opening of the inner polytetrafluoroethylene layer takes on 180 degrees with the opening of the outer polytetrafluoroethylene layer, and the thickness of each polytetrafluoroethylene layer is 0.2-0.3mm, and the width of the opening is 0.5-1mm. The composite sealing O-shaped ring eliminates the contact of medium with the rubber ring in structure, and keeps the contact of the medium with the polytetrafluoroethylene in the use process, therefore, has excellent elasticity and corrosion resistance.
Description
Technical field
The utility model relates to a kind of Sealing, relates in particular to a kind of " O " RunddichtringO.
Background technique
" O " type rubber ring is modal Sealing, also is the main Sealing of consumption maximum, and material mainly contains fluorine rubber, nitrile butadiene rubber, silicone rubber, ethylene propylene rubber, because himself hardness is little, distortion and resilience are good, so good seal performance.Because rubber " O " RunddichtringO material belongs to organic substance, so corrosion resistance is subjected to the restriction of medium, serviceability temperature also is restricted when having a lot of media to be difficult to find suitable rubber material.Teflon is a kind of material of almost anti-all corrosion, adopted in a large number in the corrosion field and promote, but himself hardness is higher, and with " O " type circle hardness height of its making, amount of deformation is little, so its sealability is not good, causes and can't use.
Summary of the invention
At the defective that existing " O " RunddichtringO exists, the utility model proposes a kind of good seal performance, corrosion-resistant, " O " RunddichtringO of flexible type not.
For addressing the above problem, technical solution adopted in the utility model is: a kind of compound seal " O " type circle, it is characterized in that: rubber " O " type circle outer wrap one deck internal layer polytetrafluoroethylene floor, the internal layer polytetrafluoroethylene floor is shaped on opening, at the outer polytetrafluoroethylene floor of internal layer polytetrafluoroethylene floor outer wrapping one deck, outer polytetrafluoroethylene floor opening and internal layer polytetrafluoroethylene floor opening are 180 degree.
The beneficial effects of the utility model: the favorable elasticity of the utility model compound seal " O " type circle bound rubber itself and superior the two advantage separately of corrosion resistance of teflon, adopt moulding cutter processing technology, at the two-layer polytetrafluoroethylene floor of base rubber " O " type circle outer wrap, internal layer polytetrafluoroethylene floor opening and outer polytetrafluoroethylene floor opening are 180 degree, every strata tetrafluoroethylene layer thickness is 0.2～0.3mm, A/F 0.5～1mm; Stopped contacting of medium and rubber ring from structure, in use medium only contact with teflon, makes " O " type of sealing circle have a fine flexible while, and is corrosion-resistant again.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure: 1 rubber " O " type circle, 2 internal layer polytetrafluoroethylene floors, 3 outer polytetrafluoroethylene floor 4 openings
Embodiment
A kind of compound seal " O " type circle, as shown in Figure 1, adopt moulding cutter processing technology, at rubber " O " type circle 1 outer wrap one deck internal layer polytetrafluoroethylene floor 2, internal layer polytetrafluoroethylene floor 2 is shaped on opening 4, and at the outer polytetrafluoroethylene floor 3 of internal layer polytetrafluoroethylene floor 2 outer wrapping one decks, outer polytetrafluoroethylene floor 3 openings 4 are 180 degree with internal layer polytetrafluoroethylene floor 2 openings 4, every strata tetrafluoroethylene layer thickness is 0.2～0.3mm, opening 4 width 0.5～1mm.
Stopped contacting of medium and rubber ring from structure, so in use medium only contacts with teflon, makes the new product to have the fine flexible while, and is corrosion-resistant again.
