Abstract
The invention relates to the technical field of expansion joints, in particular to a novel fully-buried expansion joint which comprises a flow guide pipe and a corrugated pipe. The corrugated pipe is arranged on the outer wall of the flow guide pipe and is a stainless steel corrugated pipe, an expandable graphite layer and a high-temperature injected agent layer are sequentially arranged on the outer wall of the corrugated pipe, and a rubber pipe is arranged on the outer wall of the high-temperature injected agent layer. The novel fully-buried expansion joint is provided with an external pressure flexible sealing structure and an additional expandable graphite and high-temperature injected agent sealing structure, the surface layer water permeation resistance of the novel fully-buried expansion joint is temperature-resistant, reliable and durable, accordingly, the novel fully-buried expansion joint does not need to be regularly maintained or replaced, and the production cost can be effectively reduced. The novel fully-buried expansion joint has the advantages of simple structure, long service life, high operational reliability and the like.
Description
Technical field
The present invention relates to the expansion joint technical field, be specifically related to the novel expansion joint that entirely buries.
Background technique
Nowadays, be embedded in the underground length for delivery of high temperature, high-pressure medium apart from heat supply pipeline, the wall thickness of expansion joint is large, intensity is higher.In using process, the extending amount produced due to heat supply pipeline is larger, and the bellows wave number is more, the bellows of expansion joint, easily because local leakage appears in fatigue, therefore needs periodic maintenance or changes expansion joint, causes the working life of expansion joint shorter, the workload of safeguarding and changing is large, and cost is higher.
Summary of the invention
The purpose of this invention is to provide that a kind of simple in structure, high temperature resistant, corrosion protection, sealing are reliable, long service life, the novel expansion joint that entirely buries that reduces production costs.
In order to solve the existing problem of background technique, the present invention is by the following technical solutions: the novel expansion joint that entirely buries, the bellows that comprises honeycomb duct and be located at described honeycomb duct outer wall, described bellows is corrugated stainless steel tubing, the outer wall of described bellows is provided with expanded graphite layer and high temperature injecting layer successively, and the outer wall of described high temperature injecting layer is provided with sebific duct.
Further, described sebific duct is PE sebific duct or PVC sebific duct.
The present invention has following beneficial effect: the novel expansion joint that entirely buries of the present invention, mainly comprise honeycomb duct and the bellows of being located at the honeycomb duct outer wall, wherein, bellows is corrugated stainless steel tubing, and the outer wall at bellows is provided with expanded graphite layer and high temperature injecting layer successively, and the outer wall of high temperature injecting layer is provided with sebific duct; The present invention adopts outside the external pressure flexible sealing structure, has increased expanded graphite and high temperature injecting sealing configuration simultaneously, and to stoping surface layer water accessibility, more heatproof, more reliably and more lasting, therefore, without periodic maintenance or replacing, effectively reduce production costs.In addition, the present invention has the characteristics such as simple in structure, long service life, functional reliability be good.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
As shown in Figure 1, the novel expansion joint that entirely buries, the bellows 2 that comprises honeycomb duct 1 and be located at described honeycomb duct 1 outer wall, described bellows 2 is corrugated stainless steel tubing, the outer wall of described bellows 2 is provided with expanded graphite layer 3 and high temperature injecting layer 4 successively, and the outer wall of described high temperature injecting layer 4 is provided with sebific duct 5.In the present embodiment, add expanded graphite in expanded graphite layer, and add the high temperature injecting in high temperature injecting layer, like this can be effectively to stoping surface layer water accessibility, more heatproof, more reliably, more lasting.
As shown in Figure 1, described sebific duct 5 is PE sebific duct or PVC sebific duct, and design, make this expansion joint have extremely strong corrosion resistance and ageing resistance like this, effectively extends its working life.
Finally explanation is, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, other modifications that those of ordinary skills make technological scheme of the present invention or be equal to replacement, only otherwise break away from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of claim scope of the present invention.
Claims (2)
