Problems solved by technology
[0006] In order to make up for the deficiencies of the existing technology and solve the lack of wear protection of the outer circumference of the hose in the prior art, a protective tube supported by a wear-resistant material for the jacket is usually used for protection to reduce the wear on the hose, but the gap between the hose and the protective tube The degree of bending between them is different, which makes the hose and the protective tube slide against each other, increasing the wear of the hose. At the same time, when the existing protective tube is connected to the flange, the protective tube needs to be expanded so that the protective tube is close to the flange. The inner diameter of one end is slightly larger than the outer diameter of the flange, and then the flange can be inserted into the protective tube, and the protective tube and the flange are fastened by the hoop. The nylon thread does not have strong elasticity, so that the nylon thread will be torn off after the protective tube expands, reducing the strength of the protective tube.

Embodiment approach
[0026] As an embodiment of the present invention, the end of the protection tube 11 close to the flange 12 is embedded with an expansion ring 15, and the expansion ring 15 is an annular reinforcing rope arranged in a zigzag shape; the flange 12 is inserted into the inner tube 1 and the protection tube 12. between the pipes 11; the expansion ring 15 increases the strength of the protective pipe 11 when it expands, and increases the connection strength between the flange 12 and the protective pipe 11; when the existing protective pipe 11 is connected to the flange 12, the protective pipe 11 needs to be expanded. The inner diameter of the end of the protective pipe 11 close to the flange 12 is slightly larger than the outer diameter of the flange 12, and then the flange 12 can be inserted into the protective pipe 11, and the protective pipe 11 and the flange 12 are fastened by the hoop, but the protective During the expansion process of the tube 11, since the mesh nylon thread emb...

The invention belongs to the technical field of hoses, and specifically relates to a wear-resistant thermoplastic hose, which includes an inner tube; a wear-resistant protective tube is set on the outer circumference of the inner tube, and the gap fits between the protective tube and the inner tube, and the inner tube One end is fixedly connected with a flange; there is a set of ring grooves between the inner pipe and the protective pipe, and talc powder is installed in the ring grooves. The friction between the inner pipe and the protective pipe is reduced by talcum powder, and the wear resistance of the inner pipe is increased; In the invention, a group of ring grooves are opened between the inner tube and the protective tube, and talcum powder is installed in the ring grooves, so that a small amount of talcum powder enters the gap between the inner tube and the protective tube when the inner tube bends, thereby reducing the amount of damage between the inner tube and the protective tube. The friction between them reduces the wear on the outer circumference of the inner tube and increases the wear resistance of the inner tube.
Description
technical field [0001] The invention belongs to the technical field of hoses, in particular to a wear-resistant thermoplastic hose. Background technique [0002] Hoses are vital components in modern industry. Hoses are mainly used as wire and cable protection tubes for wires, cables, automated instrument signals, and civil shower hoses, with specifications ranging from 3mm to 150mm. Small-diameter hose (3mm-25mm inner diameter) is mainly used for the protection of sensing lines of precision optical rulers and industrial sensor lines. [0003] According to the purpose, it is mainly divided into: threading hose, drainage hose, ventilation hose, shower hose, wire harness tube. According to the material, it is mainly divided into: stainless steel hose, metal hose, corrugated hose, rubber hose, plastic hose. [0004] There are two types of plastic hoses, one is completely airtight and watertight, such as propellant delivery for launch vehicles, gas, water heaters; the other pl...
