Specific implementation mode

The utility model is described in further detail below in conjunction with attached drawing.

The design principle of the utility model is：

When crack occurs in pipeline, water is flowed out from internal layer 1 makes anhydrous slufuric acid copper powders change colour across powder bed 4, water flowing The anhydrous cupric sulfate of discoloration is taken at outer layer 8, because powder is with water flowing, then so that water is changed colour；It is attached to after water oozes out outer layer 8 On 8 outer end face of outer layer, outer layer 8 is also made to catch color, maintenance personnel need to only observe 8 color change portion of outer layer at this time, you can know this There is crack in place's pipeline, and then can in time be repaired before crack growth, improves the degree of safety of pipeline.

Embodiment：A kind of fire extinguisher canvas hose with detection rupture location, in conjunction with Fig. 2, Fig. 3, including internal layer 1, lines layer 2, Internal layer 1 is regular circle shapes tubulose, and internal layer 1 is made of high-density polyethylene material, so that internal layer is had using high-density polyethylene material There is certain wear-resisting, corrosion resistant performance of acid-proof；Lines layer 2 is wrapped in outside internal layer 1, and lines layer 2 is several columned rubber strips Around being formed, by the way that lines layer 2 is arranged, the toughness of pipeline is improved, the probability of mechanical destruction is reduced.

In conjunction with Fig. 2, Fig. 3, lines layer 2 is wrapped with two layers of detection layers 3, and detection layers 3 are made of aluminum alloy materials, detection layers Powder bed 4 is filled between 3, dusty material is anhydrous cupric sulfate；When crack occurs in pipeline, water is flowed out from internal layer 1 across powder Last layer 4 makes anhydrous slufuric acid copper powders change colour, and water flowing takes the anhydrous cupric sulfate of discoloration at outer layer 8 to, because powder is with water flowing, Then water is made to change colour；It is attached on 8 outer end face of outer layer after water oozes out outer layer 8, so that outer layer 8 is caught color, at this time maintenance personnel 8 color change portion of outer layer only need to be observed, you can know that crack occurs in pipeline herein, and then can in time be repaired before crack growth, Improve the degree of safety of pipeline；Oxidation film is generated by the part that aluminium alloy is contacted with powder bed 4 in detection layers 3 simultaneously, and then makes powder Last layer 4 is not easy to contact with the external world under normal circumstances, avoids corrosion pipeline other parts, and aluminium alloy also has good knot Structure intensity, makes pipeline be not easily broken.
