Description
Technical field
The utility model relates to electric heater unit, particularly relates to cold-proof, the attemperator of Transport Machinery and industrial pipeline, equipment.
Background technology
In China northern territory, winter, many outdoor locations needed warming.Such as petroleum pipeline, the fuel pipe of water lines, various motor vehicle, lubricating system machine oil pipeline and the various valve body of braking system and pipeline, because the high and cold security incident that causes of low temperature and to affect event a lot.For maintenance equipment normally runs, need working temperature to remain on more than safe temperature.
CN 2755405Y patent teaches a kind of composition structure of flexible cold-proof heat insulation electric jacket, and it solves the cold-proof problem that the equipment such as rolling stock is afraid of to freeze position preferably, achieves waterproof, grease proofing, windproof, antidetonation and easy to loading and unloading to a certain extent.Its weak point mainly contains: waterproof technology is loaded down with trivial details and waterproof rank is not high; Main insulation material is not fire-retardant; Insulation material water absorption rate is too high; Several large problem that innermost layer material conducts heat uniformity is not high and the interior layer material life-span is shorter.
Utility model content
The purpose of this utility model is to provide a kind of safe, reliable, practical electric heater unit, utilize equipment self-powered or other facilitate power supply, solve the warming work needing the parts of heating and thermal insulation of various shape.According to the objective environment situation that product uses, the utility model design has taken into full account the requirements such as fire-retardant fireproof, insulation, anti-ice-snow (protection against the tide), waterproof and oilproof.
The technical scheme in the invention for solving the technical problem is: a kind of novel cold-proof electric jacket; be made up of aluminium foil cloth heat-conducting layer, zone of heating, insulating barrier, rubber and plastic heat-insulation layer and overcoat; described zone of heating has insulation by a kind of flexible heater body and one, heatproof, waterproof, grease proofing sealant form a good flexible heater layer of sealing; this flexible heater layer is fixed between insulating barrier and heat-conducting layer; outside insulating barrier; cover a heat-insulation layer and external protection successively again, form described electric jacket.
Further, flexible heater body, preferred flexible electric heating membrane calandria, or flexible electrical heated filament calandria, its minimum bending radius is 5 millimeters.
Further, electric jacket thickness is 5-8 millimeter.
Further, flexible electrical heated filament and power line are integrated compression molding, composition electric-heating assembly joint.
Further, rubber and plastic heat-insulation layer possesses closed foaming structure.
Further, aluminium foil cloth protective layer for possessing low water absorption, the aluminium foil cloth protective layer of high flame retardant.
Further, external protection is provided with double buckle at fastening place.
For showing superiority of the present utility model, the heat insulating ability of this product and thermal conductivity are proved by following test.
(1) heat-insulating property test: the electric jacket that the electric jacket selecting different manufacturers insulating rubber plastic to make and felt make totally 3 covers does contrast test, electric jacket is connected on DC110V voltage, be energized 15 minutes, artificial leather is pressed after making it be adjacent to heating wire and test electric jacket surface temperature with point thermometer, measure the weight of electric jacket, soak after 4 hours, again measure the weight of electric jacket.Compare temperature rise and the water absorption rate of 3 cover electric jackets, judge insulation and water resistance with this.
(2) Test on Heat Conduction: the electric jacket made of fire retardant and aluminium foil cloth choosing that resistance closely (is considered as resistance identical) is each a set of, on two cover samples, choose same position point for measuring temperature respectively, 8 passage probes are fixed on the location point chosen, be energized 30Min respectively, counting.Relatively the average temperature rising of 8 points for measuring temperature, judges heat conduction uniformity with this.
The beneficial effects of the utility model: heat-conducting layer heat conduction evenly, is easily cut out, abrasion resistance is high, high flame retardant, low water absorption, product reaches more than 10000 hours useful life; Eliminate at former flexible electrical heated filament and power line junction joint with glue filling, the loaded down with trivial details technique of hot melt contracting, is improved to physical abrasion method, greatly strengthen reliability and the waterproof and oilproof performance of connection, more than immersion insulation property are high 1 order of magnitude; Eliminate the double-deck design of former insulating barrier, retain individual layer, because heat-conducting layer aluminium foil cloth properties of materials, while Assurance component insulating protection does not reduce, reduce the loss of heat in transmission, production technology is also simplified; Heat-insulation layer insulation effect is excellent, saves heat energy loss, and high flame retardant, and other insulation material of Thickness Ratio is thin over halfly can reach identical heat insulation effect; Closed bubble structure make steam not easily through, water absorption rate is low, and product is rich in flexibility, processing install very convenient, labor and material saving.
