The utility model has the advantages of simple and reasonable structure, good temperature retention, better integrity, good aging resistance, easy mounting, handy dismantling, repeatable exploitation time after time, long service life, low manufacturing and service cost, and with the popularization of application, the utility model can reduce a mass of heat loss, save energy resources, and can widely be applied to the heat insulating for the flange on the heat pipe line in the industries of oil refining, petrochemical, electric power, chemical fiber, fertilizer, pharmacy, metallurgy and oil field etc.
Description
Technical field
The utility model relates to a kind of flange lagging, is used for the insulation of hot pipeline piping flange.
Background technique
Along with the develop rapidly of national economy, the energy-conservation common concern that more and more is subjected to people.The speed of enterprise economic growth depends on the energy to a great extent, is an important energy saving measure and strengthen being incubated, reduce thermal loss.This is because the radiation loss of equipment and pipeline and annex thereof occupies critical role in the energy consumption of enterprise.With the oil play is example, and the flange in its process units is countless.And the flange of pipeline and pipeline junction is owing to need overhaul, suppress, change, and because flange is complex-shaped, frequent switch, and its insulation problem fails better to be solved always, and major part is disposable insulation, and flange is opened and inspect, and is incubated destruction thereupon.Also have part to adopt manual manufacture, manual beaing with galvanized sheet iron made thermal case, is buckled on the flange, and in order to insulation, but intensity is extremely low, and liner is loose, and when flange need be opened and inspect, its incubation chamber is deformed damaged thereupon also.In recent years, part enterprise adopts glass fibre reinforced plastics casing, liner insulating lining, its shortcoming is that glass fibre reinforced plastics adopts organic resin to make by hand mostly, and heatproof is low, the fireproof performance extreme difference, when meeting high temperature, glass fibre reinforced plastics is softening naturally to catch fire, very harmful to keeping the safety in production, glass fibre reinforced plastics also wears out in the sun easily, fades, intensity is low, and working life is short, the cost height, dismounting inconvenience also is unfavorable for repeating repeatedly to use.
Summary of the invention
The purpose of this utility model is to provide a kind of flange lagging, and good heat insulating is installed easily, and convenient disassembly can repeat repeatedly to use, long service life, and manufacturing cost and use cost is low.
Flange lagging described in the utility model, be lined with thermal insulation layer in the shell, the inner chamber of thermal insulation layer and the shell shape of flange adapt, its lagging is the two style structure that fastens mutually, correspondence is provided with to fasten to lock and buckles on the two stamped metal shells, thermal insulation layer is the integral structure of typing, and metal shell has the invagination flange that is folded to thermal insulation layer on the edge.
Two style structure is made, is installed easily, convenient disassembly, during use two bodies are directly fastened on the flange and get final product the overall structure behind the fastening, good heat insulating with buckling to be locked, bulk strength is big, and overall performance is good, metal shell, as galvanized sheet iron, aluminum alloy, sheet metal etc., intensity is big, ageing-resistant, does not burn, reliable fully, dismountable in addition structure has prolonged working life of product greatly, has reduced cost.
Metal shell is bonding by tackiness agent with inboard thermal insulation layer, and overall performance is good, and bulk strength is big.
On the surface of internal cavity of thermal insulation layer, be coated with high-temperature agglomerant, avoid scattering and disappearing of thermal insulation layer, stop the flange heat dissipation effectively after guaranteeing to install, improve thermal insulation property, and the tackiness agent on surface has also increased the surface strength of thermal insulation layer.
Thermal insulation layer can be any thermal insulating material that is fit to, and is made through glued mold pressing by ceramic fiber, and resistance to high temperature is good, in light weight, intensity is big, and, elasticity is moderate, compressible surplus is big, and resilience is big, and percent thermal shrinkage is little, Gu shape property is good, lagging is closely contacted with flange body, guaranteed the stability and the sealing of thermal insulation layer, go back sound-absorbing damping, ventilative, waterproof.
Metal shell of the present utility model can design according to the flange of all size, pressure rating in the industrial production, drawn, suppresses, is welded, and cooperates the profile of flange, and integrity is strong, and is both artistic and practical.Consider simultaneously and the pipeline flange of flange coupling and the flange insulation of flange body, can effectively stop the pipeline flange of flange coupling and the radiation loss of flange body, the leakage of avoiding the exposed operation of flange to cause being subjected to the variation of ambient temperature that flange bolt is expanded with heat and contract with cold causing.
The utility model flange lagging, simple and reasonable, good heat insulating, integrity is strong, and is anti-aging, installs easily, convenient disassembly, can repeat repeatedly to use, long service life, manufacturing cost and use cost is low, it is applied, can reduce a large amount of thermal loss, save the energy, can be widely used in refining oil, the insulation of hot pipeline piping flange in the every profession and trades such as petrochemical industry, electric power, chemical fibre, chemical fertilizer, pharmacy, metallurgy, oil field.
Description of drawings
Fig. 1, the utility model one example structure schematic representation.
The plan view of Fig. 2, Fig. 1.
The rear view of Fig. 3, Fig. 1.
Among the figure: 1, thermal insulation layer inner chamber 2, thermal insulation layer 3, locking buckle 4,5, metal shell in-flanges 6, metal shell.
Embodiment
The utility model is described in further detail below in conjunction with embodiment's accompanying drawing.
As shown in the figure, flange lagging described in the utility model, be lined with thermal insulation layer 2 in the shell 6, the inner chamber 1 of thermal insulation layer 2 adapts with the shell shape of flange, the two style structure (accompanying drawing be depicted as wherein a part) of its lagging for fastening mutually, correspondence is provided with to fasten to lock and buckles 3 on the two stamped metal shells 6, and thermal insulation layer 2 is made through glued mold pressing by ceramic fiber, be the integral structure of typing, metal shell 6 has the invagination flange 4,5 that is folded to thermal insulation layer 2 on the edge.Metal shell 6 is bonded together with the thermal insulation layer 2 of inboard, scribbles high-temperature agglomerant on the surface of internal cavity of thermal insulation layer 2.
Two bodies with structure during use directly are fastened on the flange, get final product with buckling accordingly to be locked, and thermal insulation layer has good insulation effect to flange.
