Description

Multi-layer formed water supply and drainage pipe

The technical field is as follows:

the utility model belongs to the technical field of water supply and drainage tubular product, concretely relates to fashioned water supply and drainage tubular product of multilayer.

Background art:

at present, pipes made of PE (polyethylene) made of single materials are adopted in the market, the strength is low, the pipes are easy to damage, when the pipes with higher strength are needed, the strength and the toughness of products can be realized only by increasing the thickness, or the pipes made of the PE materials are adopted, the strength is not enough, when the pipes need to be buried or are in special occasions, the pipes cannot be used, particularly, the thickness is increased, the cost of the products is increased, particularly, the later maintenance is troublesome, the related maintenance cost is continuously increased, the strength and the toughness of the pipes are increased by adopting a method for increasing the thickness, and the hidden trouble that the pipes cannot be installed or cannot be laid can be brought to a construction party.

On the other hand, in many cases, especially on the basis of infrastructure, under the precondition that the thickness of the pipe is not changed, the pipe does not have enough strength, the technical requirements cannot be met, the heavy loss of a user is easily caused, and especially, the external and internal compressive strengths are easily caused to be insufficient, the pipe is easily damaged, and accidents are caused.

Moreover, when the single PE pipe is buried in a humid or acid-base environment, the outer circular surface of the single PE pipe is corroded, and the single PE pipe slowly corrodes through along with the passage of time, so that accidents are easily caused, potential safety hazards exist, and the service life is shortened.

In order to overcome the technical problems, from the practical viewpoint, the inventor has conducted long-time research and discloses a multi-layer formed water supply and drainage pipe.

The utility model has the following contents:

an object of the utility model is to provide a fashioned water supply and drainage tubular product of multilayer to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a multi-layer formed water supply and drainage tube, comprising: interior PE pipe 1, vertical thread 2, winding layer 3 and weaving layer 4, interior PE pipe 1 outside is provided with vertical thread 2, vertical thread 2 outside is equipped with winding layer 3, 3 outsides on winding layer are equipped with weaving layer 4.

Preferably, the longitudinal yarns 2 are parallel to the central line of the inner PE pipe 1, the winding layer 3 is of a multilayer annular spiral structure, and the weaving layer 4 is of a staggered weaving structure.

Compared with the prior art, the utility model provides a fashioned water supply and drainage tubular product of multilayer possesses following beneficial effect:

1. the PE pipe with the multilayer molding has the advantages that the strength is increased under the condition that the original thickness is unchanged, the PE pipe is not easy to damage and cannot be used due to the increase of the thickness, the cost and the maintenance cost in the later period cannot be increased by adopting the structure, the hidden danger that the PE pipe cannot be installed or laid on a construction side does not exist, and the potential safety hazard does not exist.

2. Under the moist or acid-base environment, the multilayer formed pipe cannot be corroded, so that safety accidents cannot be caused, potential safety hazards do not exist, and the service life of the pipe is prolonged.

Description of the drawings:
