Abstract
The utility model provides a high performance sealing pad piece and is composed of a corrosion resistant metal plate and a flexible graphite plate. The corrosion resistant metal plate and the flexible graphite plate through being riveted are pressed into the tightly combined integral sealing plate material. The sealing plate material can be cropped or punched into pads with different shapes according to the need. The high performance sealing pad piece is used in sealing auxiliaries of various liquid body mechanical devices. The high performance sealing pad piece has the advantages of reliable sealing, high mechanical strength, good repetitive using performance, good high temperature bearing, strong corrosion prevention, simple manufacturing technique and low cost.
Description
The utility model relates to the gasket seal that uses in a kind of fluid mechanical device, specifically a kind of high-performance gasket seal of high temperature resistant, anti-deep-etching.
Gasket seal is the Primary Component of fluid mechanical device valve etc., and one to being world's engineering circle inquiry order.All once carry out a series of pads as the pressurized container research committee (PVRC) of AAE American Association of Engineers (ASME) and U.S. welding EASD (WRC) and be connected experiment and analytical work under the cyclic high-temperature load, formulated new pad parameter list and model.But hitherto known high-performance gasket seal is asbestos packing sheet pad, spiral wound gaskets and cladding pad etc. its shortcoming is arranged all:
The asbestos packing sheet pad is the most frequently used high-temperature sealing gasket, and its outstanding key is that asbestos belong to carcinogen, and by being forbidden in the world, and its mechanical strength is low, and repeat performance is poor, and the high-temperature-resistant and anti-corrosion performance is not high yet;
The service condition of spiral wound gaskets is harsh, and formability is poor, and the cost height is had relatively high expectations to sealing surface;
The manufacturing process that coats pad is more complicated, and is also relatively poor to sealing surface requirement height and repeat performance.
Task of the present utility model is to provide a kind of mechanical strength height, high temperature resistant, anti-strong corruption, good seal performance and the low high-performance gasket seal of the simple and easy cost of manufacturing process.
Pad of the present utility model is formed by flexible graphite plate and metal mesh panels compacting.This sheet metal is the corrosion resistant metal thin plate, and the plate upper punch is shaped on mesh, and its surface then riveting is covered with one deck flexible graphite plate, forms the integral sealing sheet material that a sheetmetal and flexible graphite plate are combined closely.Promptly between two-layer pure flexible graphite plate up and down, accompany a metal mesh panels, the repressed flexible graphite plate that forms the two-sided compound enhancing that is closely as one, this plate can be cut into the pad of different shape as required, is used in the sealing of different fluid mechanical device.
Because Expanded graphite has the decay resistance of the wide temperature range that can bear-200 ℃ to 3300 ℃ and full medium scope, and the strong radiating spokes of ability shines, also have good ductility and thickness elasticity and excellent self lubricity and to the good characteristics such as impermeability of gas, liquid, when making sealing material, available lower fastening pressure can be realized sealing fully.But pure flexible graphite article, mechanical strength is low, is easy to damage in shaping, transportation and using process, so pure Expanded graphite at present in Sealings such as fluid mechanical device valve, is generally only made filler usefulness.
The utility model high-performance gasket seal has fully been drawn the advantage of Expanded graphite as sealing material, has solved the low shortcoming of pure Expanded graphite mechanical strength again.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is for coating gasket construction figure, and its outsourcing sheet metal 1 links with seaming form and cover plate 2, and forming a cavity is asbestos slate or flexible graphite plate with packaging material material 3 in placing.Its manufacturing process is more complicated, and the outsourcing sheet metal is easily damaged by complications, and also higher to the sealing surface processing request, sealability is bad.
Accompanying drawing 2 is the utility model high-performance gasket seal structural drawing.Corrosion-resistant metal sheet 4 upper punches are shaped on mesh 5, and flexible graphite plate 6 promptly overlays on two surfaces of sheet metal 4 by mesh 5 rivetings, form a whole refractory seal sheet material of combining closely.
Accompanying drawing 3 is embodiment's 1 high-performance gasket seal structural drawing of the present utility model.Corrosion-resistant metal sheet 4 is the OCr19Ni9 corrosion resistant plate, and its thickness is 0.2 millimeter, and mesh aperture is 0.6 millimeter, and mesh density is per 10 millimeters
22 holes, it is 1.5～1.7 gram per centimeters that flexible graphite plate adopts density
3, rebound degree is greater than 65%, and compressibility is 10～20% flexible graphite plate, can be applicable to flowing mediums such as water, oil, hot coal oil, inorganic acid, Applicable temperature≤450 ℃, suitable pressure is 1.6MPa.
Another embodiment's of the present utility model corrosion-resistant sheet metal 4 usefulness inconel steel plates (INCONEL), thickness of slab is 0.5 millimeter, and mesh aperture is 1 millimeter, and mesh density is per 10 millimeters
21 hole.This patch applications is in strong corrosive mediums such as hydrofluoric acid, and Applicable temperature is 1100 ℃.Surplus with embodiment 1.
The utility model since on the corrosion resistant metal thin plate riveting be covered with flexible graphite plate, the two combines closely into whole high-performance sealing plate material, can cut out as required or punching out becomes the pad of different shape, during the sealing that is applied to the different fluid mechanical device is paid.Its mechanical strength height, seal reliable, easy to use, can high temperature resistant, anti-deep-etching, and manufacturing process is simple and easy, with low cost.
Claims (3)
1, a kind of high-performance gasket seal, form by corrosion resistant metal thin plate 4 and flexible graphite plate 6, it is characterized in that having mesh 5 on this sheetmetal 4, flexible graphite plate 6 overlays on two surfaces of sheet metal 4 by mesh 5 rivetings, form a whole high-performance sealing plate material of combining closely, can cut out as required or punching out becomes the pad of different shape, be applied to the sealing of different fluid mechanical device and pay.
2, according to the described gasket seal of claim 1, it is characterized in that corrosion resistant metal thin plate 4 is the OCr19Ni9 corrosion resistant plate, thickness is 0.2 millimeter, and mesh aperture is 0.6 millimeter, and the density of flexible graphite plate is 1.5～1.7 gram per centimeters
3, rebound degree is greater than 65%, and compressibility is 10-20%.
3, according to the described gasket seal of claim 1, it is characterized in that corrosion-resistant sheet metal 4 is Inco nickel (Inconel) alloy sheets, thickness of slab is 0.5 millimeter, mesh aperture is 1 millimeter.
