Environment-friendly explosion-proof PE pipe with good stability

Abstract

The invention relates to the field of explosion-proof PE pipes, in particular to an environment-friendly explosion-proof PE pipe with good stability. The PE pipe comprises half pipe bodies; explosion-proof mechanisms are arranged on the surfaces of the two half pipe bodies; pressing mechanisms are arranged on the surfaces of the explosion-proof mechanisms; and fixing mechanisms are arranged on thesurfaces of the explosion-proof mechanisms. Two PE half pipe bodies with proper lengths are correspondingly spliced, the two half pipe bodies are arranged on the surface of a to-be-reinforced pipeline in a sleeving mode, then multiple threaded columns are clamped in corresponding clamping holes, four half cylinders are connected to the two ends of the half pipe bodies in a sleeving mode, meanwhile, inner sleeves are sleeved with the two corresponding half cylinders, then two fixing cylinders are connected to the surfaces of the four half cylinders in a sleeving mode, the half cylinders are fixed through the fixing cylinders, the inner sleeves are extruded through fixing rings, clamping rings clamped in the inner sleeves face the half pipe bodies, triangular pressing blocks on the clampingrings are clamped in triangular grooves, then the half pipe bodies are fixed in the half cylinders, the PE pipe is protected through the half pipe bodies, and the PE pipe is prevented from being burst under pressure.

Description

technical field [0001] The invention relates to the field of explosion-proof PE pipes, in particular to an environment-friendly explosion-proof PE pipe with good stability and performance. Background technique [0002] PE pipe, also known as polyethylene pipe, is a kind of plastic pipe. PE pipe is used in a wide range of fields, among which water supply pipe and gas pipe are its two largest application markets. PE resin is polymerized from monomer ethylene. Due to different polymerization reaction conditions such as pressure and temperature during polymerization, resins with different densities can be obtained, and PE pipes made of resins with different densities can adapt to different use requirements. [0003] Existing PE pipes are often used as water supply pipes. When the inside of the PE pipe is filled with water in cold weather, the water flow inside the pipe will condense, and the condensed water will expand, which will cause pressure on the inner wall of the PE pipe....

AI Technical Summary

Problems solved by technology

[0004] PE pipes in the prior art are often used as water supply pipes. When the inside of the PE pipe is filled with water flow in cold weather, the water flow inside the pipe will condense, and the condensed water flow will expand, which will cause pressure on the inner wall of the PE pipe. When the pressure inside the pipeline is too high, it will cause the pipeline to burst, which will cause the pipeline to leak and become unusable, and it is necessary to replace the PE pipe with a high-strength metal pipe, but there are a lot of problems in the existing water supply system that cannot adapt to the cold Weather PE pipes, these pipes will still burst in cold weather and cause pipe leakage. The present invention provides an environmentally friendly explosion-proof PE pipe with good stability and performance.
