Intelligent prefabricated directly buried cross-linked polyethylene insulation pipe fitting elbow alarm line fixing method

Abstract

Provided is a method for fixing alarm lines of an intelligent prefabricated directly-buried crosslinked polyethylene thermal insulation pipe fitting elbow. At present, no intelligent device is available for prefabricated directly-buried thermal insulation pipes applied to the heating and cooling field at home, no intelligent device is available for a thermal insulation pipe elbow fitting with a crosslinked polyethylene working pipeline, and consequently breakage of the pipeline cannot be found in time, dangerous circumstances cannot be eliminated in time, a great amount of energy leaks, energy consumption is increased, and pollutant emission is increased. The method for fixing the alarm lines of the intelligent prefabricated directly-buried crosslinked polyethylene thermal insulation pipe fitting elbow involves the crosslinked polyethylene working pipe elbow (3), the crosslinked polyethylene working pipe elbow is connected with a polyurethane thermal insulation layer (2), and the polyurethane thermal insulation layer is connected with an outer protecting pipe (1), supports (5), the alarm lines (4) and an alarm line installation strip (6). The method is used for installing the alarm lines of the pipeline.

Description

Technical field: [0001] The invention relates to an intelligent prefabricated direct-buried cross-linked polyethylene thermal insulation pipe fitting elbow alarm line fixing method, which is applied to the intelligent prefabricated direct-buried in the product system of prefabricated direct-buried thermal insulation pipes used in the field of heating and cooling. The installation and fixing method of the alarm line in the elbow fittings of the insulation pipe. Background technique: [0002] At present, the prefabricated direct-buried thermal insulation pipes used in the heating and cooling fields in China do not have intelligent devices, and there are no intelligent devices in the thermal insulation pipe elbow fittings with cross-linked polyethylene as the working pipeline, which leads to the failure of the pipeline to be detected and repaired in time. Excluding dangerous situations will cause a large amount of energy leakage, increase energy consumption, and increase pollut...

AI Technical Summary

Problems solved by technology

[0002] At present, the prefabricated direct-buried thermal insulation pipes used in the heating and cooling fields in China do not have intelligent devices. In the middle, there is no smart device, so the damage of the pipeline cannot be detected and eliminated in time, resulting in a large amount of energy leakage, increased energy consumption, and increased pollution emissions.
