Abstract
The utility model provides a heating device in a liquid pipe. The heating device comprises a power supply and a heating belt. The heating belt is composed of heating wires and an insulating sheath coating the heating wires. The power supply is connected with the heating wires. The beneficial effects of the utility model are that, compared with external heating, thermal energy generated by in-pipe heating can be transmitted to the liquid inside the pipe by 100%, and the operation environment inside the pipe is more stable than that outside the pipe, thereby prolonging the service life of a heater; and as long as the heating belt is in normal operation, the liquid pipe within the length of the heating belt is ensured not to be frozen, so that frozen points can be easily determined and found out without digging up or breaking the insulating layer, thereby facilitating the maintenance, replacement or installation. The heating device provided by the utility model is easy in installation, and is particularly suitable for regions in a critical state, and can be mounted in existed pipes without digging up the pipes.
Description
Technical field
The utility model relates to the heater in a kind of liquid line.
Background technology
Cold winter, usually can occur freezing in outdoor fluid pipeline, prior art is to be enclosed with heating tape and insulation material at the outer surface of liquid (running water or former wet goods) pipeline, there is following shortcoming in this structure of insulation material: the indivedual local breakages of insulation material or the area for critical condition, cold makes certain part in pipeline occur freezing, often be difficult for finding freezing place, delay use, and while needing Maintenance and Repair, outermost insulation material must accurately excavate and dismantle, it is very inconvenient to operate, and waste insulation material, and can not exempt to dig to the pipeline using and install or maintenance.
Utility model content
The utility model, in order to solve the problem in background technology, provides the heater in a kind of liquid line.
Technical solution of the present utility model is:
Heater in liquid line, its special character is: comprise power supply and heating tape, described heating tape comprises the insulating outer layer of heater strip and parcel heater strip, and described power supply is connected with heater strip.
The material of above-mentioned insulating outer layer is acid-proof or oil resisting material.
The material of above-mentioned insulating outer layer is anti-base material.
Above-mentioned insulating outer layer outer surface is coated with corrosion-resistant coating.
Above-mentioned heater also comprises the elastic wire being arranged in insulating outer layer, described elastic wire and heater strip isolation.
The cross section of above-mentioned heating tape is rounded or oblate.
The utility model has the advantages that: pipeline interior heating, compared with external heat, adds thermogenetic heat energy and can 100% passes to liquid in pipe in pipe, the operational environment in pipe is more relatively stable than the environment outside pipe, can extend the useful life of heater; As long as heating tape is working properly, in the length of heating tape, assurance is not frozen, and easily judges and searches chill point, without digging out or destroy heat-insulation layer, just can keep in repair and change or install, install easily, the area that is particularly suitable for critical condition can be installed at any time and exempt to excavate in existing pipeline.
Accompanying drawing explanation
Fig. 1 is the utility model circular cross-section schematic diagram;
Fig. 2 is the oblate schematic cross-section of the utility model;
Wherein: 1-heater strip; 2-elastic wire; 3-insulating outer layer; 4-corrosion-resistant coating.
Embodiment
Heater in liquid line, comprises power supply and heating tape, and heating tape comprises the insulating outer layer 3 of heater strip 1 and parcel heater strip, and described power supply is connected with heater strip.
The material acid-proof of insulating outer layer, oil resistant, alkali prevention, to adapt to various liquid environments, for example, in water supply pipe environment, select rubber or reach the standard material of packaging for foodstuff; In environment, select oil resistant outer covering material at conveying crude oil.
Or insulating outer layer is selected common material, be coated with acid-proof, alkali prevention, grease proofing corrosion-resistant coating 4 at insulating outer layer outer surface.
Heater also comprises the elastic wire being arranged in insulating outer layer, and the isolation of elastic wire and heater strip the adding of elastic wire is convenient to heater and better in pipe, is advanced.
It is oblate that the cross section of heating tape is, and as Fig. 2, but circular as Fig. 1, is convenient to heater strip and is introduced from the accessory of pipe ends, and easily sealing.
When use, heater strip is introduced from the seal fitting of pipeline, until next break valve is provided with seal nipple on the break valve accessory of pipeline.
Seal nipple can be selected conventional cable clip tightening seal joint, and as the DQM of Yueqing City Yi Kesi Electric Applicance Co., Ltd series cable clip tightening seal joint, material is high-quality steel or stainless steel or engineering plastics or aluminium alloy, mechanical type cable clip tightening seal joint.
