High-strength compression-resistant PVC pipe with organic fiber reinforced layer

Abstract

The invention discloses a high-strength compression-resistant PVC pipe with an organic fiber reinforced layer.The high-strength compression-resistant PVC pipe comprises a pipeline body, the pipeline body comprises an inner pipe and an outer pipe, the outer side of the inner pipe is provided with the organic fiber reinforcing layer, the outer side of the organic fiber reinforcing layer is provided with a compression-resistant layer, the outer side of the compression-resistant layer is provided with a locking mechanism, and the outer side of the compression-resistant layer is provided with a locking mechanism. A steel wire mesh layer is arranged on the locking mechanism, and a buffering structure is arranged between the outer pipe and the compression-resistant layer; the invention relates to the technical field of pipes. According to the high-strength compression-resistant PVC pipe provided with the organic fiber reinforced layer, the two ends of two sets of buffer bent plates between the outer pipe and the compression-resistant layer move towards the two sides and are tightly attached to the pressing plate, meanwhile, the buffer bent plates deform to extrude penetrating buffering bags, and the situation that when damage occurs, the outer pipe extrudes the inner pipe inwards under the action of external force, damage to the inner pipe is increased is prevented. And meanwhile, the buffering bag and the supporting piece can play a role in speed reduction, an auxiliary force unloading role can be played, and the buffering performance of the buffering structure is enhanced.

Description

technical field [0001] The invention relates to the technical field of pipe materials, in particular to a high-strength compression-resistant PVC pipe provided with an organic fiber reinforcement layer. Background technique [0002] PVC pipe is rigid polyvinyl chloride pipe, which is extruded by hot pressing after combining polyvinyl chloride resin with stabilizer, lubricant, etc. It is the earliest plastic pipe to be developed and applied. PVC pipe has strong corrosion resistance, easy bonding, low price, and hard texture. However, due to the leakage of PVC monomer and additives, it is only suitable for water supply systems with a delivery temperature not exceeding 45°C. Plastic piping is used in applications for drainage, waste water, chemicals, heating and cooling fluids, food, ultrapure liquids, slurries, gases, compressed air and vacuum systems. [0003] However, during the transportation, installation and use of existing PVC pipes, they will be extruded by external fo...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a high-strength compression-resistant PVC pipe provided with an organic fiber reinforced layer, which solves the problem that the existing PVC pipe will be extruded by external forces during transportation, installation and use. Ordinary PVC pipes are not strong enough, and the pipes will break, which wastes resources and increases production costs.
