Multi-layer pressure-resistant pipeline

Abstract

The invention relates to a multi-layer pressure-resistant pipeline. The multi-layer pressure-resistant pipeline comprises a main pipeline and a multi-layer pressure-resistant pipeline main body, wherein the multi-layer pressure-resistant pipeline main body comprises a first protection pipe layer, a second protection pipe layer and a third protection pipe layer, a placing area is arranged in the first protection pipe layer, protrusions are connected with the outer side wall of the first protection pipe layer, an installation area is arranged in the second protection pipe layer, the inner wall of the second protection pipe layer is connected with connecting blocks, clamping grooves are formed in the side walls of the connecting blocks, and the first protection pipe layer is arranged in the second protection pipe layer in a penetrating mode. According to the multi-layer pressure-resistant pipeline, the multiple protection pipe layers are adopted for protecting the main pipeline, and buffering balls of plastic hollow structures are distributed between the third protection pipe layer and the second protection pipe layer, so that deformation buffering can be conducted on external pressure to prevent the situation that the pressure is directly transferred to an internal pipeline structure to damage the main pipeline, meanwhile, a pressure-resistant buffering area where the buffering balls are located can provide a buffering area for the pressed pipeline, meanwhile, direct heat transfer to the internal pipeline due to external heating is avoided, and thus the multi-layer pressure-resistant pipeline has a certain heat insulation effect.

Description

technical field [0001] The invention relates to the technical field of pressure-resistant pipelines, in particular to a multilayer pressure-resistant pipeline. Background technique [0002] In the past ten years, driven by the rapid development of my country's macro economy, my country's plastic pipes have experienced rapid development in the context of the rapid development of chemical building materials. Plastic pipes are widely used in building water supply and drainage, urban and rural water supply and drainage, urban gas, electric power and optical cable protection. Sets, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields. The plastic pipes in the prior art are generally buried at a certain depth underground, which requires higher pressure resistance of the plastic pipes. When heavy objects pass directly above the plastic pipes, the plastic pipes may be damaged. The pressure will cause damage an...
