Abstract
The utility model relates to a polytetrafluoroethylene-coated rubber sealing gasket, which is characterized in that a rubber gasket is used as an inner layer, both sides of the inner layer are respectively provided with an outer polytetrafluoroethylene-gasket layer, and the inner rubber-gasket layer and the outer polytetrafluoroethylene-gasket layers at both sides of the inner layer are bonded together through an adhesive; and the surface of each outer polytetrafluoroethylene-gasket layer is provided with an annular convex edge which is matched with an annular groove on a flange sealing surface. A handle of the polytetrafluoroethylene-coated rubber sealing gasket and the inner rubber-gasket layer are formed into an integrated structure. The polytetrafluoroethylene-coated rubber sealing gasket has the advantages of high-temperature resistance and corrosion resistance, and the sealing performance can be further improved. The service life is long, and the operating expense is saved.
Description
Technical field
The present invention relates to a kind of sealing gasket, relate to specifically the rubber-coated sealing gasket of a kind of teflon.
Background technique
At present, the employed sealing of numerous industries such as oil refining, petrochemical industry, chemical industry, medicine, heat supply generally mostly is slabstone pad or rubber plastic pad with pad.This sealing gasket, sealing effect is poor, and working life is short, and operating cost is high.When oil refining, petrochemical industry, chemical industry, medicine, the annual general overhaul of heating industry, the every valve that will dismantle, flange, almost described sealing gasket is all wanted subscription rate, needs again to change.
Summary of the invention
Purpose of the present invention provides a kind of teflon rubber-coated sealing gasket in the problem that overcomes the prior art existence, to improve sealing effect, long service life etc.
Technological scheme of the present invention is: the rubber-coated sealing gasket of a kind of teflon, it is characterized in that: take rubber pad as internal layer, these internal layer both sides are that teflon gasket is outer, pass through adhesive bond together between rubber pad internal layer and this internal layer both sides teflon gasket skin; Have shape and structure with flangeseal face coupling on the described teflon gasket superficies; The sealing pad is provided with handle.
The rubber-coated sealing gasket of above-mentioned teflon, that have on its described teflon gasket superficies and shape and structure flangeseal face coupling, refer to the teflon gasket superficies have with the flangeseal face on the annular ridge of annular groove coupling.
The rubber-coated sealing gasket of the teflon of the above, it is characterized in that: described handle and rubber pad internal layer are structure as a whole.
The present invention compared with prior art has following advantage: 1) the present invention is high temperature resistant, and is corrosion-resistant.2) can further improve sealability.3) long service life, the energy-saving run expense.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure, 1-internal layer (rubber pad); 2-outer (teflon gasket); 3-handle; 4-annular ridge.
Embodiment
Below by embodiment also by reference to the accompanying drawings, the invention will be further described.
As seen from Figure 1, the present invention: the rubber-coated sealing gasket of a kind of teflon, it is characterized in that: take rubber pad as internal layer 1, these internal layer 1 both sides are teflon gasket skin 2, are bonded together by tackiness agent between rubber pad internal layer 1 and this internal layer both sides teflon gasket skin 2; Have shape and structure with flangeseal face coupling on the described teflon gasket superficies; The sealing pad is provided with handle 3.
The rubber-coated sealing gasket of above-mentioned teflon, that have and shape and structure flangeseal face coupling on outer 2 surfaces of its described teflon gasket, refer to the outer 2 surperficial cloth of teflon gasket have with the flangeseal face on the annular ridge 4 of annular groove coupling.
The rubber-coated sealing gasket of the teflon of the above, its described handle 3 is structure as a whole with rubber pad internal layer 1.
Claims (3)
