Pressure-resistant pipeline

Technical Field

The utility model belongs to the technical field of the pipeline technique and specifically relates to a withstand voltage pipeline is related to.

Background

The pipeline is a device which is connected by pipes, pipe connectors, valves and the like and is used for conveying gas, liquid or fluid with solid particles, and the pipeline is widely applied to multiple industries and fields due to the unique characteristics of the pipeline. In modern life, people can not leave various pipes which are closely related to life, such as most direct pipelines with the specification of a tap water series, pipelines with the specification of a sewer series, pipelines with the specification of a heating series, pipelines with the specification of a gas series and pipelines with various specifications required by industry. As the gas temperature is higher and higher, the pressure is increased, which poses a serious challenge to the safety of the high-temperature and high-pressure pipeline, and at the same time, the pipeline also ensures a smaller heat dissipation amount while ensuring the safety so as to prevent a larger heat loss. In order to meet the two requirements, the existing heat-insulating pipeline generally adopts heat-resistant and pressure-resistant alloy materials, a thick heat-insulating layer is wrapped outside the pipeline, and the heat-resistant and pressure-resistant alloy materials are very expensive, so that the investment cost of the system is greatly increased, the heat-resistant and pressure-resistant pipeline with reasonable price and simple preparation becomes the market demand, and the inconvenience is brought to the transportation construction due to the large mass of the alloy pipeline. On the other hand, the alloy pipeline has poor corrosion resistance and high cost. At present, the PE, PVC and PP pipelines exist, and the application range of the pipelines is limited due to the low pressure resistance and simple structure of the pipelines in the structural design problem.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes prior art's defect provides a low cost, and simple structure is fit for most of liquid, gaseous state material under different environment, especially under the comparatively harsh environment, still can satisfy the withstand voltage pipeline of pipeline transportation requirement. Compared with the common PE pipeline, the pipeline has the advantages that when the same compressive strength is achieved, raw materials are saved, the production and use cost is reduced, and the pipeline has excellent characteristics incomparable to other pipelines.

The technical scheme of the utility model is that: the utility model provides a withstand voltage pipeline, includes the interior pipeline, and the interior pipeline outside is provided with the fibrous layer, and the fibrous layer outside is provided with the thickening layer, and the outside of thickening layer is provided with the outer pipeline, and the space that interior pipeline and fibrous layer enclose is provided with spring and support rubber, and spring and support rubber interval arrangement set up, and the both ends of spring contact with interior pipeline, fibrous layer point respectively, and the both ends of supporting rubber contact with interior pipeline, fibrous layer face respectively.

Furthermore, the fiber layer is formed by tightly winding 3 to 5 layers of fibers, the winding direction of each layer of fibers is the same, and the winding direction of each layer of fibers is different.

Further, the thickening layer is a porous structure.

Further, the cross sections of the inner pipeline and the outer pipeline are in a regular hexagon shape.

Furthermore, the material of the inner pipeline is HDPE resin.

Furthermore, the material of outer pipeline is soft rubber.
