The heating tube can prevent the permeation of liquid and has a long service life.
Description
Technical field
The utility model relates to a kind of heat-generating pipe, relates in particular to a kind of outgoing wire at one end heat-generating pipe.
Background technology
Electric heating element circle heat-generating pipe is generally in dry combustion method and does not contact water, wet goods conductor or semiconductor, even if electric wire adopts the energy such as silica gel line or the single of heatproof 300-400 ℃ left and right, mica line high temperature resistant not wear-resisting also.In manufacturing process, just simply magnesia powder is filled in heat-generating pipe, at seal location exposed magnesia powder without hesitation, though also there is part heat-generating pipe to seal at single silica gel, ceramic glue, pottery for nozzle position, while there is water, wet goods fluid conductors or semiconductor in the operational environment of heat-generating pipe, these conductors or semiconductor will infilter in heat-generating pipe, cause the problems such as heat-generating pipe short circuit, damage.Heat-generating pipe electric wire except heatproof 300-400 ℃, wear-resisting, prevent infiltration, all do not done other aspect oil impregnate and process, even if there be silica gel or even the gum sleeve that has also just simply put 300 ℃ of left and right of one deck energy heatproof.Under at rugged environment, as in high temperature (more than 400 ℃), the adverse circumstances such as dynamic, moist, the useful life of heat-generating pipe is extremely short.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of outgoing wire at one end heat-generating pipe, can immerse by anti-liquid, even if liquid immerses, also there will not be short circuit or corrosion failure, its long service life.
To achieve these goals; the utility model provides a kind of outgoing wire at one end heat-generating pipe; comprise cold junction, heating part and power line; heating part comprises heating wire and the first body; between heating wire and the first body, be filled with solid insulation; cold junction is positioned at heating part two ends, and cold junction is filled with solid insulation, at the cold junction that is provided with power line, is also provided with some layers of high-temperature plastic for sealing in the outside of solid insulation; Power line is connected with heating wire.
According to described outgoing wire at one end heat-generating pipe, described cold junction is also provided with ceramic plug.
According to described outgoing wire at one end heat-generating pipe, described heating wire is also coated with high-temperature insulating layer outward.
According to described outgoing wire at one end heat-generating pipe, described solid insulation is magnesium oxide.
According to described outgoing wire at one end heat-generating pipe, described power line is pure nickel line or mica line.
According to described outgoing wire at one end heat-generating pipe, also comprise insulation mandrel, heating wire is wrapped in insulation mandrel periphery.
According to described outgoing wire at one end heat-generating pipe, described insulation mandrel adopts magnesium oxide to make.
The outgoing wire at one end heat-generating pipe that the utility model provides, owing to adopting high-temperature plastic and ceramic plug to seal cold junction, has avoided outside liquid immersion; Separately, because being further coated high-temperature insulating layer in heating wire periphery, even if also there will not be the faults such as short circuit when liquid flows into, and can more than 400 ℃ in environment, work, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment outgoing wire at one end heat-generating pipe;
Fig. 2 is the A-A generalized section of Fig. 1.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Outgoing wire at one end heat-generating pipe of the present utility model comprises cold junction, heating part and power line; heating part comprises heating wire and the first body; between heating wire and the first body, be filled with solid insulation; cold junction is positioned at heating part two ends; at the cold junction near heating part, be filled with solid insulation, at the cold junction that is provided with power line one end, in the outside of solid insulation, be also provided with some layers of high-temperature plastic for sealing; Power line is connected with heating wire.
Further, at above-mentioned cold junction, be also provided with ceramic plug, for fire-proof insulation.
Further, above-mentioned heating wire is also coated with high-temperature insulating layer outward.
Owing to adopting high-temperature plastic and ceramic plug to seal cold junction, avoided outside liquid immersion, also played good insulating effect; Another because being further coated high-temperature insulating layer in heating wire periphery, even if also there will not be the faults such as short circuit when liquid flows into.
