Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution: a heat tracing anti-freezing pipeline comprises a pipeline body 1, wherein the pipeline body 1 comprises a transmission layer 2, the transmission layer 2 is of a PE structure, the PE structure is thermoplastic resin prepared by polymerizing ethylene, the low temperature resistance is good, the flexibility can be kept at low temperature, the electric insulation is high, the service life of the transmission layer 2 is prolonged, a plastic layer 3 is fixed on the outer surface of the transmission layer 2, heating wires 4 are plastically packaged in the plastic layer 3, the number of the heating wires 4 is 9, the diameters of the heating wires 4 can be determined according to the length and the temperature requirements of a pipe, the value range of the diameters of the heating wires 4 is 0.8 mm-1.5 mm, heat tracing is carried out on the pipeline body 1 by generating heat through the heating wires 4, the pipeline body 1 can be kept in a specified temperature range in a cold area, and the phenomenon that the pipeline body 1 is frozen and blocked can be prevented, carry out the plastic envelope through crossing plastic layer 3 to heating wire 4 to it is longer to make the life of heating wire 4, the external fixed surface who crosses plastic layer 3 has enhancement layer 5, enhancement layer 5 sets up to glass fiber structure, and glass fiber's the biggest characteristic is that tensile strength is big to there is good electrical insulation, is advanced electrical insulation material, and coefficient of elasticity is good, and the rigidity is good, is fit for as the enhancement layer, 5 external fixed surfaces of enhancement layer have signal layer 6, signal layer 6 includes two signal reception units, can receive the temperature of pipeline each place through signal layer 6, then the very first time feedback, the external fixed surface of signal layer 6 has outer protective layer 7, outer protective layer 7 sets up to the PE structure, can improve outer protective layer 7's life.

The working principle is as follows: this heat tracing anti-freezing pipeline is when using, comes to accompany heat to pipeline body 1 through heating wire 4 production heat to prevent that the phenomenon of freezing stifled from appearing in pipeline body 1, the life of this example can be improved to the transmission layer 2 and the outer protective layer 7 of PE structure simultaneously, and the enhancement layer 5 of the fine structure of glass can improve the tensile strength of this example simultaneously, thereby improves the life of this example.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
