Abstract
The utility model discloses a high-strength graphitic sandwiched sealing gasket coated with teflon which solves the problems of poor capability and easy damage of the existing rubber plate sandwiched sealing gasket coated with teflon and the existing rubber graphitic sandwiched sealing gasket coated with teflon which can not satisfy the requirement of producing and using. The novel sealing gasket is the integrated structure composed of a sandwiched ring, a flexible graphite sheet, and a metal sheet ring. The utility model is characterized in that multiple layers of flexible graphite sheets and multiple layers metal sheets with a plurality of holes are arranged in the middle of the interlayer of the sandwiched ring; the surface layer is provided with once formed clips with teflon connected with each other. The utility model which has the advantages of flat surface, high accurate strength, and good sealing can be used widely in various kinds of liquid gas devices to extinguish running, emitting, dripping, and leaking.
Description
The utility model relates to gasket seal.
Existing teflon rubberizing plate and rubberizing graphite cake interlayer gasket seal, expansion character is poor, and compressive strength is low, and particularly the narrow heavy caliber pad in limit uses unstablely, very easily damages, bursts apart, weeping happens occasionally, and sealing effect is not ideal enough.
The purpose of this utility model is the defective that exists at above-mentioned gasket seal, structurally makes improvements, to overcome these defectives.A kind of sealing effect better seal pad is provided.
The purpose of this utility model is achieved in that teflon bag high-strength graphite interlayer gasket seal, be the overall structure of forming by interlayer circle and Expanded graphite thin plate circle and sheet metal circle, it is characterized in that being provided with layer flexible graphite thin plate in the middle of the interlayer of interlayer circle and multilayer is dashed the sheet metal that porous is arranged, surface layer is for interconnecting one-time formed teflon intermediate plate.
Above-mentioned project organization has been obtained the technique effect of expection through test.
The utility model is described in further detail below by drawings and Examples.
Fig. 1 is the utility model embodiment plane structure schematic representation.
Fig. 2 is that the back structural representation is analysed and observe in Figure 1A-A amplification.
Fig. 3 is the another embodiment's sectional structure of a utility model schematic representation.
Fig. 4 is the utility model embodiment's sectional structure schematic representation again.
Among the figure: 1. interlayer circle, 2. intermediate filler layer, 3. surface layer, 4. Expanded graphite thin plate, 5. sheetmetal, 6. metal thick plate.
As shown in the figure: teflon bag high-strength graphite interlayer gasket seal, be the overall structure of forming by interlayer circle and Expanded graphite thin plate circle and sheet metal circle, it is characterized in that being provided with layer flexible graphite thin plate 4 in the middle of the interlayer of interlayer circle 1 and multilayer is dashed the sheet metal that porous is arranged, promptly intermediate filler layer 2 be that layer flexible graphite thin plate 4 and multilayer are towards the sandwich structure of being made up of the sheet metal of porous; Surface layer 3 is for interconnecting one-time formed teflon intermediate plate.As shown in Figure 2: intermediate filler layer 2 is the sandwich structure that four layers of Expanded graphite thin plate 4 and double layer of metal thin plate 5 arranged in a crossed manner reach middle layer of metal slab 6 compositions; As shown in Figure 3: intermediate filler layer 2 is six layers of Expanded graphite thin plate 4 and the four layers of metal foil power 5 arranged in a crossed manner and the sandwich structure of middle layer of metal slab 6 compositions.As shown in Figure 4: intermediate filler layer 2 is the sandwich structure that eight layers of Expanded graphite thin plate 4 and six layers of sheetmetal 5 arranged in a crossed manner reach middle layer of metal slab 6 compositions.
The gasket seal of above-mentioned same structural type different size, good integrity not only, surfacing, size is precise and stable, intensity is enough, and long service life has good plasticity and filling, has solved enamel lining, glass lining, fluorine and has moulded the coarse problems with the pad difficulty of other liner seal faces such as lining.Be applicable to the connection sealing position of equipment such as all kinds of gas pipelines, valve, pressurized container and heat exchanger, can be widely used in departments such as oil, chemical industry, metallurgy, space flight, military project, electric power, pharmacy, papermaking and nuclear industry, to the run, drip, leak in the thorough elimination production, steady production, increase the output value, reduce to pollute, improve environment all tool greatly act on economy and obvious social benefit.
