Preferably, the inner resin layer has a smooth cylindrical tubular structure.
Preferably, the inner resin layer and the spiral corrugated layer are low-permeability high-strength resin hoses made of food-grade or medical-grade soft high-low temperature resistant plastic resin materials, more preferably reinforced polyethylene PE materials, and the outer resin layer is an elastic resin hose resistant to UV and environmental corrosion, more preferably TPE materials.
Compared with the prior art, the utility model has the following beneficial effects:
1. The spiral corrugated multilayer resin composite hose has the advantages that the inner layer is made of soft high-low temperature resistant plastic resin materials, the temperature resistant range of polyethylene is about-60 ℃ to 110 ℃ under the normal use condition, the common working temperature is-40 to 90 ℃, the spiral corrugated multilayer resin composite hose has the characteristics of corrosion resistance, wear resistance, high compressive strength, flame retardance, good flexibility and the like, can be suitable for common occasions and can be widely used in the food and medicine industries with higher requirements on hose materials, the outer layer is made of TPE, is a thermoplastic elastomer material, is also called thermoplastic rubber, is an elastic resin hose resistant to UV and environmental corrosion, and is good in fatigue resistance and temperature resistance, excellent in processing performance and low in cost.
2. The inner tube of the spiral corrugated multi-layer resin composite hose is of a smooth cylindrical tubular structure, and the problems that the inner tube of the composite corrugated hose in the market is of a corrugated structure (corrugation) directly, so that a large amount of small vortex is generated when liquid flows through the inner tube, the water resistance is increased, and the flow speed and the flow quantity of the liquid are reduced are solved.
3. The spiral corrugated multi-layer resin composite hose has the advantages that the spiral corrugated structure is good in bending performance, winding resistance and twisting resistance, compression resistance and stretching resistance are 1.2 times that of a common corrugated hose, and the heat insulation performance of the hose is improved by the spiral gaps.
