Abstract
The utility model relates to a polytetrafluoroethylene coated silicon rubber sealing gasket. The polytetrafluoroethylene coated silicon rubber sealing gasket is characterized by consisting of an inner layer of silicon rubber and an outer layer of polytetrafluoroethylene gasket; the inner layer and the outer later are adhered together through adhesive; and annular convex arris matched with an annular groove on a sealing surface of a flange disc is formed on the surface of the outer layer of polytetrafluoroethylene gasket. The handle of the sealing gasket and the inner layer of silicon rubber form an integrated structure. The polytetrafluoroethylene coated silicon rubber sealing gasket is simple in structure, scientific and reasonable and can obviously improve the sealing property. The polytetrafluoroethylene coated silicon rubber sealing gasket has the characteristics of long service life, reusability, low operating and maintenance cost and the like.
Description
Technical field
The invention belongs to sealing gasket, relate to a kind of teflon coated Si rubber gasket.
Background technique
Sealing gasket is oil, oil refining, petrochemical industry, pharmacy, chemical industry, for pad, power industry a kind of sealed product generally.The most asbestos packings of the gasket seal that often uses in existing market and production.This material seal weak effect, working life is short, the operating cost high.When every because equipment, pipeline flange place water clock keeped in repair, old sealing gasket can only be dismantled more renewed.Particularly during annual general overhaul, change gasket seal more, safeguard change loaded down with trivial details, the effort of taking a lot of work.
Summary of the invention
The object of the invention is to overcome the problem that existing technology exists, a kind of teflon coated Si rubber gasket is provided, to improve sealing effect, reduce operating cost etc.
Technological scheme of the present invention is: a kind of teflon coated Si rubber gasket is characterized in that: the internal layer of silicone rubber, the skin of teflon gasket are arranged; Be connected as a single entity by tackiness agent between described internal layer and skin; Have shape and the structure of mating with the flangeseal face on the superficies of described teflon gasket, the sealing pad is provided with handle.
Above-mentioned a kind of teflon coated Si rubber gasket, have shape and structure with flangeseal face coupling on its described teflon gasket superficies, refer to the teflon gasket superficies be provided with the flangeseal face on the annular ridge of annular groove coupling.
Above-mentioned a kind of teflon coated Si rubber gasket, the internal layer of its described handle and silicone rubber is into a single integrated structure.
The present invention compared with prior art has the following advantages: 1) adopt heat to melt compacting, sealability is significantly improved; 2) long service life; Can repeatedly repeat 3) simple in structure, scientific and reasonable.4) easy to maintenance.
Description of drawings
Fig. 1 is structural representation of the present invention.
In figure, 1-internal layer (silicone rubber); 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.A kind of teflon coated Si rubber gasket is characterized in that: the internal layer 1 of silicone rubber, the skin 2 of teflon gasket are arranged; Be connected as a single entity by tackiness agent between described internal layer 1 and outer 2; Described teflon gasket has shape and the structure of mating with the flangeseal face on outer 2 surfaces, and the sealing pad is provided with handle 3.
Above-mentioned a kind of teflon coated Si rubber gasket, have shape and structure with flangeseal face coupling on outer 2 surfaces of its described teflon gasket, refer to teflon outer 2 surfaces be provided with the flangeseal face on the annular ridge 4 of annular groove coupling.
Above-mentioned a kind of polyvinylfluoride coated Si rubber gasket, its described handle 3 is into a single integrated structure with the internal layer 1 of silicone rubber.
The present invention has simple in structure, and is scientific and reasonable, and sealability is significantly improved, and long service life can be repeatedly used, characteristics easy to maintenance.
