Abstract
The utility model provides a pipeline insulation anti-freezing heat-tracing device, which comprises a voltage control module consisting of single-phase solid voltage regulators and electric heating wires, wherein the voltage control module and the electric heating wires are connected; the electric heating wires consist of nichrome electric heating wires in an insulating material outer layer. According to the technical scheme, the power supply voltage is stably reduced to safe working voltage which meets the set technical requirements of insulation anti-freezing heating by the single-phase solid voltage regulators, and the pipeline insulation anti-freezing heat-tracing device is suitable for pipeline laying and implementation of heat insulation work, low in power consumption, high in safety and fire-free and is easy to mount and use, and overall electric heating operation is stable and reliable.
Description
Technical field
The utility model relates to pipeline electric heating thermal insulation freezing preventer.
Background technique
The outdoor water pipe line cabling of northern area need to install thermal-insulating freezing-resistant apparatus additional and freeze, blocks even the bursting by freezing pipeline preventing, a class thermal-insulating freezing-resistant apparatus wherein is the electrical heating band, and typical practical example is the electrical heating band of solar water heater upper and lower conduit pipeline of being laid in.This insulation is mixed the torrid zone and is made of belt carcass and insulating outer layer; connect the 220V civil power work that loads on; form one between two parallel heart yearns of ribbon heater and keep continuously parallel heating element; the technical problem underlying that this pipeline heat insulation is mixed torrid zone existence includes: power consumption is high; every meter is mixed tropical power is 25W; the torrid zone of mixing in 4 meters long; its power consumption is 100W; there is again the self structure of being comparatively fragile; and be difficult to find electric breakpoint or its hidden danger; one section not hot phenomenon of one section heat often can appear; weaken even without the heat-preserving anti-freezing effect; its three be since the certain areas power supply voltage extremely unstable; the reason such as inclement weather causes and mixes torrid zone damage and have the hidden danger of catching fire in addition, is difficult to guarantee safety in utilization.
Summary of the invention
Goal of the invention of the present utility model be to overcome existing mix tropical fragile structure, be difficult to adapt to condition of power supply unstable and under the stern climate condition technical problem such as rapid wear, provide a kind of in supply variation and inclement weather still the antifreeze hot charging of mixing of pipeline heat insulation of stable, reliable heat insulation work put, it also has the technical characterstic of low power consumption work.The antifreeze hot charging of mixing of the pipeline heat insulation that the utility model provides is put technological scheme, its main technical content is: the antifreeze hot charging of mixing of a kind of pipeline heat insulation is put, comprise that the voltage control module and the electrically-heated-wire that are made of single-phase solid pressure governor connect and compose, described electrically-heated-wire is made of the nichrome electric heating wire in the insulating material skin.
The antifreeze hot charging of mixing of the disclosed pipeline heat insulation of the utility model is put technological scheme, the operating voltage that is required by the single-phase solid pressure governor heat-preserving anti-freezing heating technique of being down to safer and satisfied setting that power supply voltage is stable, and having the outer field nichrome electric heating wire of insulating material is suitable for laying pipeline, implements heat insulation work, reliable, the failure rate is low of whole electric heating working stability, power consumption is low, safe, the nothing fire is suffered from, and also has the technological merit that is easy to install and use.
Description of drawings
Accompanying drawing is mixed the electric circuit constitute block diagram that hot charging is put for this pipeline heat insulation is antifreeze.
Embodiment
The antifreeze hot charging of mixing of this pipeline heat insulation is put, connected and composed by voltage control module, electrically-heated-wire and heat protector, as shown in drawings, voltage control module is to be made of single-phase solid pressure governor, input end connects in the civil power 220V power supply line, the reduced output voltage load voltage, in the present embodiment output is set as the 36V load voltage; Described electrically-heated-wire is to be made of the outer nichrome electric heating wire that wraps up of insulating material, be connected in the output terminal and ground end of voltage control module, its insulating material skin is by having good loose warm nature energy, has simultaneously waterproof, insulating material heat-resisting, creep resistance is made, as selects F46 etc.The specific design of this device will according to setting heating temperature scope, solid pressure governor amount of exports fixed load magnitude of voltage and load current value, finally be determined electrically-heated-wire resistance value and nichrome wire wire diameter, length.Use as example with water insulation about the solar water heater, the heating temperature that sets electric heating wire is 40-50 ℃, normally can satisfy the antifreeze requirement of northern area pipeline heat insulation.In the circuit to be provided with heat protector too high and arrange for fear of the electric heating wire operating temperature, it is series in the circuit, induction arranges near the electric heating wire mounting point, the operating temperature of influence electricity heated filament is implemented overheated power-off protection.Solid pressure governor output loading magnitude of voltage is 36V, comprehensively comes to determine wire diameter and the resistance per unit length value of nichrome wire.Mix heat as the insulation of solar water heater upper and lower conduit road and use, the gage length of its electrically-heated-wire is generally 6 meters, and its total specified power is 15-20W only, and power consumption reduces greatly.
Claims (2)
1. the antifreeze hot charging of mixing of pipeline heat insulation is put, and it is characterized in that this device comprises that the voltage control module and the electrically-heated-wire that are made of single-phase solid pressure governor connect and compose, and described electrically-heated-wire is made of the nichrome electric heating wire in the insulating material skin.
2. the antifreeze hot charging of mixing of pipeline heat insulation according to claim 1 is put, and it is characterized in that being in series with in the device circuit heat protector, and heat protector arranges near the electric heating wire mounting point.
