Abstract
The invention discloses an alloy sealing ring. A fluoroplastic sealing cartridge is arranged on the outmost layer, a middle fixing shaft is arranged in the middle and is connected with a cross-shaped copper support, the copper support is filled with a filler layer, aluminum alloy supporting protrusions are connected to the outer side of the filler layer, and meanwhile, sealing ring flange connecting holes are formed in the periphery of the fluoroplastic sealing cartridge. The alloy sealing ring is high in abrasion resistance, high in corrosion resistance, reasonable in structure and high in strength.
Description
Technical field
The present invention relates to seal arrangement field, particularly relate to a kind of alloy seal circle.
Background technique
seal arrangement application widely, especially in the joint of fluid pipeline conveying, oils, liquid kind, the valve of pump class all must use seal arrangement, the effect of seal arrangement makes pipeline reach effective sealing, reach zero leakage, traditional sealing material adopts rubber material mostly, but under some rugged environment, as the high pressure of boiler tubing, with the reactor of other chemical industry, the sealing of reaction device due to temperature high, pressure is large, adopt common sealing gasket sealing effect bad, metal o-ring simultaneously, because expanding with heat and contract with cold of thermal stress causes seal ring contraction deformation, long-time use, also poorly sealed problem can be produced.
The invention provides a kind of alloy seal circle for this reason, solve conventional rubber circle easily aging, wearing and tearing, affect the problem that pipeline normally works.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of alloy seal circle, and convection cell and gas have excellent sealability, are widely used in reactor, the sealing of the valving of reaction furnace etc., has wear-and corrosion-resistant, avirulent feature, is widely used.
Described a kind of alloy seal circle, outermost surface is fluoroplastic stuffing box gland, intermediate portion is central fixed shaft, described central fixed shaft is connected to copper Steel Support, described copper Steel Support across shape, copper Steel Support alloy seal ring plays further supporting effect, and preferably, described copper Steel Support also can replace with cross stiffening rib.
Described fluoroplastic stuffing box gland is the main body of alloy seal circle, and described fluoroplastic stuffing box gland is made by fluoroplastic, and the various inorganic acid of ability, organic acid and organic solvent corrode, and can use in various high temperature occasion.
Described fluoroplastic stuffing box gland is mixed by PFA resin and PPL polyparaphenylene phenol.
PFA resin formal name used at school soluble poly tetrafluoroethylene, the fluoroplastic of newer melt-processable, the fusing point of PFA is high, density is 2.13 grams/cc to 2.16 grams/cc, and PFA is heat-resisting, cold-resistant, chemical stability, mechanicalness, insulating properties, self lubricity, folding resistance, resistance to cracking excellent.
PPL polyparaphenylene phenol, wear-resisting, sealing material ideal in the industries such as metallurgy, chemical industry, high life, high temperature resistant, simultaneously, polyparaphenylene good thermal stability, corrosion resistance, self-lubricating property is better than molybdenum disulfide and graphite, the molecular chain of PPL, due to very large rigidity and regularity, make it cannot not be molten insoluble, self machine shaping difficulty, need fill the blended use of other materials.
A kind of optimal technical scheme, described central fixed shaft, adopts clamping bolt.
Be filled with packing layer between described copper Steel Support, described packing layer quantity is 4, and the shape of packing layer is sector form, and described packing layer adopts filled with carbon fibers layer.
Aluminum alloy support protrusion is connected with outside described packing layer, described aluminum alloy support protrusion quantity is also 4, between described aluminum alloy support protrusion, be set to groove simultaneously, groove has certain radian, described aluminum alloy support protrusion also can replace with titanium-nickel alloy, copper-zinc alloy etc.
Meanwhile, described fluoroplastic stuffing box gland periphery is provided with seal ring flange connecting hole, and seal ring flange connecting hole is convenient to seal ring and is connected with pipeline.
A kind of optimal technical scheme, described seal ring Flange joint bore dia is between 5 millimeters to 9 millimeters.
The invention has the beneficial effects as follows: a kind of alloy seal circle of the present invention, wear-resisting property is strong, corrosion-resistant good, rational in infrastructure, intensity is high simultaneously, there is excellent heat dispersion simultaneously, be widely used in chemical, the reactor of petroleum-type, be also applicable to chemical industry simultaneously, the seal for pipe joints of the industries such as medicine, has good effect equally to the sealing of the valves such as tap water.
