Abstract

The utility model relates to a hot water running water pipe, and the pipe body is a double-layer structure. One layer of the internal face is a copper pipe, and the wall thickness is between 0.5 mm and 2 mm; one layer of the external face is a plastic pipe, and the wall thickness is between 1 mm and 3 mm. The internal wall of the plastic pipe is provided with a tooth-shaped fixed rib, and the copper pipe is fastened in the plastic pipe through the fixed rib; thus, the double-layer pipe body is formed. After the utility model is used for a long time, the pipe wall does not rust and is corroded. The utility model having high durability, low cost, pressure resistance, simple structure and easy manufacture is consistent with the requirement of the national regulation, is suitable particularly for circulating the hot water, and is a novel running water pipe.

Description

The novel hot water running water pipe

The utility model relates to a kind of water pipe, particularly a kind of novel hot water running water pipe.

Existing running water pipe generally all adopts galvanized iron conduit to make, because of the easy oxide etch of iron is got rusty, so durable inadequately; And come off easily after the corrosion, human body is caused damage.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and a kind of employing double structure is provided, and corrosion-resistant, long service life, and the novel hot water running water pipe of the hot water that can be fit to circulate.

The purpose of this utility model can reach by following measure: a kind of novel running water pipe, it is characterized in that: body is divided into two-layer, inner face one deck is that copper pipe, outside one deck are plastic tube, and the plastic tube inwall is provided with the fixedly muscle of dentation, and copper pipe is clamped in the plastic layer by fixing muscle.

The purpose of this utility model can also reach by following measure; The copper pipe wall thickness is between 0.5～2mm; Plastic tube can adopt polypropylene or Polyvinylchloride or ABS plastic to make, and its thickness of pipe wall is between 1～3mm.

Fig. 1 is a structure sectional view of the present utility model;

Fig. 2 is a perspective view of the present utility model.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment);

With reference to Fig. 1～Fig. 2, the body in the utility model is a double layer construction; Inner face one deck is a copper pipe 1, and its wall thickness is 0.5～2mm; Outside one deck is a plastic tube 2, and its wall thickness is 1～3mm.Plastic tube 2 inwalls are provided with fixedly muscle 3, and copper pipe 1 is clamped in the plastic tube 2 by fixing muscle 3.Being provided with fixedly, the purpose of muscle 3 is to flow through hot water, the adverse consequences of avoiding cold shrinkage and thermal expansion to produce in order to be fit in the copper pipe.Plastic tube 2 can adopt polypropylene or Polyvinylchloride or ABS plastic to make.

The utility model has following advantage compared to existing technology: use for a long time the tube wall can be rotten Erosion is got rusty, and is durable in use, and cost is substantially the same with existing water pipe, and the withstand voltage national regulation that meets is wanted Ask, and simple and reasonable, make easily, be particularly suitable for the hot water that circulates, be a kind of novel Running water pipe.
