Abstract
The utility model discloses a tetrafluoride coated pad which comprises a tetrafluoride laminate. A corrugated metal ring is arranged in the tetrafluoride laminate, so that the radial leakage of strong acid, strong base, strong oxidant, chlorine gas, not-allowed contaminated medium and other substances are prevented, the corrosion to upper and lower contact surfaces is prevented, and after the tetrafluoride coated pad is installed, a strong elasticity is produced after the metal ring is compressed; the resilience performance of the tetrafluoride coated pad is higher than the general tetrafluoride coated pad, thus the blast protection performance of the product is improved, an ultra-low surface pressure can be adapted, and the tetrafluoride coated pad can be used in the flanged connection sensitive to pressure.
Description
Technical field
The utility model relates to the tetrafluoro coating pad that a kind of seal for pipe joints is used.
Background technique
Teflon is by the polymeric compound of tetrafluoroethylene through being polymerized; Because of its have excellent chemical stability, corrosion resistance, sealing, high lubricated not viscosity, electrical insulating property and good ageing resistance, heatproof span big; Be a kind of good sealing material, all be widely used at oil, chemical industry, pharmacy, electric power, steel industry.
It is as sandwich by cushion films such as asbestos rubber, no asbestos slate, rubber or graphite reinforcement plates that traditional tetrafluoro coats pad; The compound gasket of wrapped in teflon thin slice then, the sealing that it can be applicable to various strong acid, highly basic, strong oxidizer, chlorine and not allow pollution medium.But its resilience is lower, and the anti-burst of product can be lower, uses safety inadequately, and is difficult to adapt to ultralow pressure, can't in pressure-sensitive flange is connected, use.
Summary of the invention
The utility model is not enough to existing technology, provides a kind of tetrafluoro to coat pad, can better adapt to flanged surface and improve resilience, improves the performance of the anti-explosion of product.Can adapt to ultralow pressure, can in pressure-sensitive flange connects, use.
In order to solve the problems of the technologies described above; The utility model is able to solve through following technical proposals: a kind of tetrafluoro coats pad, comprises the tetrafluoro thin layer, is provided with undulatory metal ring in the said tetrafluoro thin layer said metal gasket ring is arranged to corrugatedly can better adapt to flanged surface and improve resilience; Improve the performance of the anti-explosion of product; Can adapt to ultralow pressure, to pressure-sensitive flange, the flange of processing like plastics, Glassed Steel.
In the technique scheme, preferred, said tetrafluoro thin layer comprises thin layer and following thin layer, and said upward thin layer and the said inner ring of thin layer down are provided with sealing block.Sealing block can protective media in the erosion of pad cross-wise direction.
In the technique scheme, concrete, the axial width of described sealing block is 3mm-5mm, the tetrafluoro protective coating axial width of internal diameter during for 3mm-5mm better protective media in the erosion of pad cross-wise direction.
The utility model compared with prior art has following beneficial effect:
Said metal gasket ring is arranged to corrugatedly can better adapt to flanged surface and improve resilience; Improve the performance of the anti-explosion of product; Can adapt to ultralow pressure, can in pressure-sensitive flange is connected, use, and can protective media in the erosion of pad cross-wise direction.
Description of drawings
Fig. 1 is the utility model embodiment's a structural drawing.
Fig. 2 is the utility model embodiment's a sectional view.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail: referring to Fig. 1 and Fig. 2, a kind of tetrafluoro coats pad, is provided with undulatory metal ring 5 in the said tetrafluoro thin layer 1.Tetrafluoro thin layer 1 comprises thin layer 2 and following thin layer 3, and the inner ring of last thin layer 2 and following thin layer 3 is provided with sealing block 4.The axial width of described sealing block 4 is 3mm-5mm, and the width that concrete present embodiment adopts is 4mm.
Sealing block 4 can fit tightly with surface of contact up and down; Prevent strong acid, highly basic, strong oxidizer, the chlorine in the pipeline and do not allow radially seepage of material such as pollution medium, just can prevent that the surface of contact place corrodes up and down, the said metal ring 5 in back is installed is compressed the bigger elastic force of back generation; Tetrafluoro coating pad resilience than common is higher; Improved the anti-burst ability of product, can adapt to ultralow pressure, can in pressure-sensitive flange is connected, use.
Claims (3)
