CN201731218U - Pipeline compensator - Google Patents

Abstract

The utility model relates to a pipeline compensator which comprises a protection layer, a thermal insulation layer, an outer sleeve, a pipe head sliding block, a baffle plate, a joint pipe and a corrugated pipe, and further comprises a metal detection wire, wherein the detection wire is embedded in the thermal insulation layer. The pipeline compensator can rapidly detect leakage points of a pipeline through the detection wire mounted in the pipeline compensator, has the advantages of simple implementation, convenient operation and low cost and can avoid terrible loss caused by leakage of the pipeline.

Description

A kind of pipeline compensator

Technical field

The present invention relates to the heating equipment field, relate in particular to a kind of pipeline compensator.

Background technique

The daily heat supply in winter in city, the north adopts the mode of hot gas, hot water heating, its conveyance conduit overwhelming majority adopts direct-buried mode, especially easier leakage the in pipeline compensator place that connect of heat supply pipeline, the gas leakage in case leak, searching and keeping in repair of fault point just becomes very big difficult point, if can not find out Pipeline Leakage Point rapidly, will bring about great losses.

The model utility content

In order to solve the problem of searching heat supply pipeline leak source difficulty, the utility model provides a kind of pipeline compensator.

The technological scheme that the utility model is adopted for achieving the above object is: a kind of pipeline compensator; comprise protective layer, thermal insulation layer, outer sleeve, tube head slide block, baffle plate, adaptor tube and bellows; it is characterized in that: comprise that also detection line, detection line are embedded in thermal insulation layer inside.

Described detection line is a plain conductor.

Pipeline compensator of the present utility model by installation and measuring line in pipeline compensator, can detect Pipeline Leakage Point rapidly, implements simply, and is easy to operate, saves cost, and avoided massive losses.

Description of drawings

Fig. 1 is the sectional drawing of the utility model pipeline compensator along the pipeline direction;

Fig. 2 is the side view of the utility model pipeline compensator;

Embodiment

Pipeline compensator as depicted in figs. 1 and 2 comprises protective layer 2, thermal insulation layer 3, outer sleeve 4, tube head slide block 5, baffle plate 6, adaptor tube 7 and bellows 8, also comprises detection line 1.Connect by bellows 8 between two adaptor tubes 7, two adaptor tubes 7 can slide at outer sleeve 4 inwalls by tube head slide block 5 and make bellows 8 flexible, outer sleeve 4 ends are provided with baffle plate 6, detection line 1 is embedded in thermal insulation layer 3 inside, detection line 1 is circle or flat plain conductor, as copper conductor and Bai Gang lead etc.One or the detection line 1 of one or more can be installed in the pipeline compensator, under the normal condition between the detection line 1 and the insulation resistance between detection line 1 and the heat supply steel pipe very big, when pipe leakage, just having ponding in the thermal insulation layer occurs, humidity can produce unusually, thus between the detection line 1 and the insulation resistance between detection line 1 and the heat supply steel pipe can diminish rapidly, extract the resistance variations signal, by analysis, can determine just whether pipeline compensator leaks to resistance variations.

Claims (2)

1. a pipeline compensator comprises protective layer, thermal insulation layer, outer sleeve, tube head slide block, baffle plate, adaptor tube and bellows, it is characterized in that: comprise that also detection line, detection line are embedded in thermal insulation layer inside.

2. a kind of pipeline compensator according to claim 1 is characterized in that: described detection line is a plain conductor.
