Abstract
The utility model relates to a plastic pipe, which is a sound insulation plastic pipe with the sound insulation effect. The wall of the sound insulation plastic pipe comprises an outer layer and an inner layer, between which a cavity layer is formed. The cavity layer is a vacuum layer or is filled with a sound insulation layer or a sound absorption layer therein, wherein the sound insulation layer or the sound absorption layer is connected together with adjacent layers. The sound insulation plastic pipe of the utility model is simple in structure and convenient in processing. Due to the arrangement of the cavity layer in the pipe wall which has a two-layer structure, the sound insulation effect can be achieved by designing the cavity layer as the vacuum layer or filling the cavity layer with the sound insulation layer or the sound absorption layer. In addition, the sound insulation effect is more ideal.
Description
Technical field
The utility model relates to a kind of plastic tube, a kind of specifically sound insulation plastic tube with soundproof effect.
Background technique
Plastic tube is a kind of common pipe fitting, be widely used in daily life and the industrial production, the tube wall of existing plastic tube mostly has single layer, is divided into pressure tube and no pressure tube, pressure tube is used for the discharge pressure fluid, can be as general conduit pipe or Conduits etc. and there is not pressure tube.Advantages such as plastic tube owing to do not have can get rusty, in light weight extensively replace metal tube at present, are applied on the water supply and sewerage pipeline.Existing plastic tube tube wall generally only has single layer, can produce bigger singing of the stream in use, and when sink drain used, the singing of the stream of generation was bigger, has directly influenced people's rest and work.The retrieval prior art, Chinese patent 97225067.0 discloses a kind of plastic tube, and the axial direction along pipe in tube wall is provided with penetrating hole pipe, and the hole pipe is laid along the circumferencial direction of tube wall.The sound insulation value that the plastic tube of this structure improves to a certain extent, and alleviated weight.But structure is too complicated, and the area of contact between the pipe internal and external layer is excessive, and soundproof effect still is not very desirable, produces inconvenience, and cost is higher.In addition, Chinese patent 00232745.7 discloses a kind of plastic tube, and its tube wall has three-decker, between skin and the middle level, be equipped with supporting bar between middle level and the internal layer, though this structure has improved soundproof effect, structure is still too assorted, and processing is inconvenient.
The model utility content
Technical problem to be solved in the utility model is: have shortcoming at above prior art, propose a kind of sound insulation plastic tube, simple in structure, easy to process, soundproof effect is even more ideal.
The technological scheme that the utility model solves above technical problem is:
Sound insulation plastic tube, its tube wall comprise a skin and an internal layer, form a cavity layer between skin and the internal layer, and cavity layer is to be filled with one deck puigging or sound-absorption layer in vacuum layer or its, and the layer that puigging or sound-absorption layer are adjacent links together.
Puigging is foam layer, spongy layer, Sound-proof material layer, PU wave Sound-proof material layer or rubber layer.Sound-absorption layer is polyester fibre sound-absorption layer, Cao Mu sound-absorption layer, hole wood sound-absorption layer or recycled wood sound-absorption layer.
Skin is polyvinyl plastics layer, the polypropylene plastics bed of material, polystyrene plastics layer or the polyvinyl chloride plastic bed of material.Internal layer is alkene plastics layer, the polypropylene plastics bed of material, polystyrene plastics layer or the polyvinyl chloride plastic bed of material.
The utility model has the advantages that: the utility model is simple in structure, easy to process, owing in the tube wall of double-layer structure, be provided with a cavity layer, be filled with one deck puigging in vacuum layer or its or sound-absorption layer can reach soundproof effect by cavity layer is made as, and soundproof effect is even more ideal.

Embodiment
Embodiment one
Present embodiment is a kind of sound insulation plastic tube, its structure as shown in Figure 1, its tube wall comprises a skin 1 and an internal layer 2, outer 1 and internal layer 2 between form a cavity layer, be filled with one deck puigging 3 in the cavity layer, puigging 3 links together with skin 1 and internal layer 2.Puigging 3 is foam layer, spongy layer, Sound-proof material layer, PU wave Sound-proof material layer or rubber layer.Outer 1 is polyvinyl plastics layer, the polypropylene plastics bed of material, polystyrene plastics layer or the polyvinyl chloride plastic bed of material.Internal layer 2 is alkene plastics layer, the polypropylene plastics bed of material, polystyrene plastics layer or the polyvinyl chloride plastic bed of material.
In the present embodiment, puigging 3 also can replace with sound-absorption layer, and sound-absorption layer is polyester fibre sound-absorption layer, Cao Mu sound-absorption layer, hole wood sound-absorption layer or recycled wood sound-absorption layer.
Present embodiment is owing to be provided with a cavity layer in the tube wall of double-layer structure, by can reaching soundproof effect with being filled with one deck puigging or sound-absorption layer in the cavity layer, and soundproof effect is even more ideal.
Embodiment two
Present embodiment is a kind of sound insulation plastic tube, its structure as shown in Figure 2, its tube wall comprises a skin 1 and an internal layer 2, outer 1 and internal layer 2 between form a cavity layer, cavity layer is a vacuum layer 4.Outer 1 is polyvinyl plastics layer, the polypropylene plastics bed of material, polystyrene plastics layer or the polyvinyl chloride plastic bed of material.Internal layer 2 is alkene plastics layer, the polypropylene plastics bed of material, polystyrene plastics layer or the polyvinyl chloride plastic bed of material.
Present embodiment is owing to be provided with a cavity layer in the tube wall of double-layer structure, by layer that cavity layer is evacuated, vacuum can conduct acoustic waves, so soundproof effect is even more ideal.
The utility model can also have other mode of execution, and the technological scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
