Abstract

The utility model discloses a double-layer durable water pipe which is composed of an inner plastic pipeline and an outer metal pipeline. The outer metal pipeline is sleeved on the inner plastic pipeline. The double-layer durable water pipe is characterized by comprising the inner plastic pipeline and the outer metal pipeline, wherein the outer metal pipeline overcomes the defect that a plastic water pipe is not firm, the inner plastic pipeline can protect the outer metal pipeline against being eroded by water and rusted, and the service life of the water pipe is prolonged; water is conveyed through the inner pipeline, if the inner pipeline is broken, the outer pipeline can continue to convey water and avoid water leakage, and the pipeline breaking conditions can be greatly reduced; the inner pipeline and the outer pipeline can be loosened, therefore when water leaks from water pipes embedded in a building, wall chiseling and ground digging are not needed, only the inner pipeline is replaced, and repairing manpower and material resources can be greatly reduced; and if the inner pipeline is made of inner-high-temperature plastics, the inner pipeline can be used as a caliducts, and due to the fact that the deformation resistance performance of plastics is strong, the problem that an iron pipe is prone to breaking in winter is solved.

Description

Double-deck durable water pipe

Technical field

The utility model relates to the piping design field, is specifically related to the durable water pipe of a kind of bilayer.

Background technique

The working individual layer pipeline of existing building mostly is plastic cement or metallic material is made, and plastic cement pipeline solidness is poor, break easily, and metallic conduit is got rusty by aqueous corrosion easily, and working life is short, and individual layer pipeline maintain and replace difficulty, has strengthened the input of manpower and materials.

The model utility content

The purpose of this utility model is to overcome above-mentioned not enough problem, provides a kind of bilayer durable water pipe.

The technological scheme that the utility model is adopted for achieving the above object is: double-deck durable water pipe, to form by plastic cement inner layer pipe and metal outer pipeline, and described metal outer pipeline is sleeved on the plastic cement inner layer pipe.

Between described plastic cement inner layer pipe and the metal outer pipeline space can be arranged.

Characteristics of the present utility model are: be made up of plastic cement inner layer pipe and metal outer pipeline, metal outer is filled up the shortcoming of plastic cement water pipe solidness difference, and plastic cement internal layer protection outer layer metal is not got rusty by aqueous corrosion, has increased water tube life-span; Water is transmitted by interior pipe, if interior tracheal rupture, it is water-tight that outer tube still can continue the transmission assurance, significantly reduces the pipeline breaking situation and take place; Can become flexible between the internal and external layer pipeline, be embedded in the water pipe of building in the body more like this when leaking, need not out wall and dig ground, only need the replacing inner layer pipe to get final product, reduce the maintenance manpower material resources in a large number; Inner layer pipe then can be used as caliduct and uses if make with interior high temperature plastic cement, because the anti-deformation nature of plastic cement is strong, therefore can solve the crackly difficult problem of iron pipe in winter.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Wherein: 1, plastic cement inner layer pipe 2, metal outer pipeline 3, space.

Embodiment

As shown in Figure 1, the utility model is made up of plastic cement inner layer pipe 1 and metal outer pipeline 2, described metal outer pipeline 2 is sleeved on the plastic cement inner layer pipe 1, water flows in plastic cement inner layer pipe 1, metal outer pipeline 2 is filled up the shortcoming of plastic cement inner layer pipe 1 solidness difference, plastic cement inner layer pipe 1 protection metal outer layer pipe 2 is not got rusty by aqueous corrosion, has increased water tube life-span; Be convenient for maintaining, between described plastic cement inner layer pipe 1 and the metal outer pipeline 2 space 3 arranged, make and to become flexible between the inside and outside pipeline, be embedded in water pipe in the building body like this when leaking, need not out wall and dig ground, only need get final product by replacing plastic cement inner layer pipe 1.

The above; it only is the preferable embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and model utility design thereof, all should be encompassed within the protection domain of the present utility model.

Claims
