Compared with the common metal hose, the service life of the double-layer anti-corrosion metal hose is greatly prolonged, and the double-layer anti-corrosion layer can prevent the working hose from being extremely bent to a certain extent; the EVA anticorrosive coating has the characteristics of corrosion resistance, long service life, shock resistance, good sound insulation, thin wall thickness and the like, so that the service life of the metal hose is greatly prolonged.
The technical scheme of the utility model as follows:
the utility model provides a double-deck anticorrosive type corrugated metal hose which characterized in that: including bellows major structure, bellows major structure's the left and right sides is connected with the adapter sleeve through the inlayer anticorrosive layer respectively, bellows major structure's the outside is equipped with the protection screen cloth, the left and right sides of protection screen cloth is equipped with the convex reinforcement safety cooperation of an outside cylinder respectively and stabilizes the post, the protection screen cloth with the outside cladding of inlayer anticorrosive layer has the EVA anticorrosive layer, the outside position of adapter sleeve is connected with the fastening connector through the welded mode, the inlayer anticorrosive layer with bellows major structure's lateral surface with be equipped with the sheath between the protection screen cloth.
Further, the hose nipple of the nipple.
Furthermore, an EVA (ethylene vinyl acetate) anticorrosive layer is also arranged on the inner side surface of the main body structure of the corrugated pipe.
Furthermore, a V-shaped welding stabilizing groove is formed at the welding position of the fastening connector and the connecting sleeve.
The utility model has the advantages that:
the EVA anticorrosive coating is coated on the corrugated pipe, so that the corrugated pipe can be protected from being corroded by external environmental factors; the outer surface of the net sleeve is covered with an EVA (ethylene vinyl acetate) anticorrosive layer, so that the net sleeve can be effectively protected from being corroded by external environmental factors on the one hand, and the corrugated pipe on the inner side is protected on the other hand. Compared with the common metal hose, the service life of the double-layer anti-corrosion metal hose is greatly prolonged, and the double-layer anti-corrosion layer can prevent the working hose from being extremely bent to a certain extent; the EVA anticorrosive coating has the characteristics of corrosion resistance, long service life, shock resistance, good sound insulation, thin wall thickness and the like, greatly prolongs the service life of the metal hose, can be suitable for places (wind power industry, coastal areas, chemical engineering places, domestic sewage places and the like) with corrosiveness to the metal hose by the external environment, and can more effectively protect the metal hose body and prolong the service life compared with the common metal hose.
