Adopt nickel-base alloy Inconel 625, Expanded graphite and these resistant to elevated temperatures materials of mica can ensure that the utility model possesses good heat-resisting quantity, the utility model can withstand high temperatures 1000 DEG C.
Certainly, described filling material strip can use the combination of mica tape and flexible graphite belt, and described mica tape and described Expanded graphite tape alternation are wound around arrangement;
Further, described metal tape is arranged between the described mica tape of arbitrary adjacent two layers and described flexible graphite belt.Adopt mica tape and Expanded graphite tape alternation to be wound around the mode of arrangement, heat-resisting quantity and the barotolerance of the spiral wound gaskets of described high temperature high voltage resistant can be ensured simultaneously.
As another kind of set-up mode of the present utility model, described filling material strip is mica tape and flexible graphite belt, and described packing ring is disposed with two-layer mica tape, three layers of flexible graphite belt and two-layer mica tape from internal layer to extension;
Further, described metal tape is arranged between the filling material strip of arbitrary adjacent two layers.Adopt above-mentioned design, heat-resisting quantity and the barotolerance of described spiral wound gaskets can be ensured, and production cost is lower simultaneously.
Preferably, described interior stiffening ring is equal with described outer annular-stiffer thickness in the axial direction; Described packing ring thickness is in the axial direction greater than the thickness of described interior stiffening ring, and in use, described packing ring can be compressed into identical with the thickness of described interior stiffening ring, to ensure the sealing of pad.
Further, described interior stiffening ring and described outer annular-stiffer thickness are in the axial direction 3mm; Described packing ring thickness is in the axial direction 4.5mm.As a kind of regular size, this thickness is widely used in every field.
The beneficial effects of the utility model are: the utility model is by adopting nickel-base alloy Inconel 625 as metallic material, nickel-base alloy Inconel 625 can tolerate the high temperature of 1000 DEG C, simultaneously, use mica tape or flexible graphite belt as non-metallic filler material, solving again natural mica can not the defect of withstand high pressures power, the utility model can tolerate the pressure of maximum 22MPa, and the utility model is convenient to produce, and has very high economic benefit.
