Abstract
The utility model discloses a soundproof plastic pipe, which is characterized in that a wall of the soundproof plastic pipe includes an outer layer and an inner layer. A cavity layer is formed between the outer layer and the inner layer and is a vacuum layer. Compared with the prior art, the soundproof plastic pipe is simple in strucutre, convenient in processing, fine in sound absorption effect and long in service life.
Description
Technical field
The utility model relates to a kind of plastic tube, relates in particular to a kind of sound insulation plastic tube.
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 simple 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.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 complicated, and processing is inconvenient.
Summary of the invention
Technical problem to be solved in the utility model is: have shortcoming at above prior art, a kind of sound insulation plastic tube is provided, simple in structure, easy to process, soundproof effect is even more ideal.
The utility model adopts following technological scheme to realize:
A kind of sound insulation plastic tube is characterized in that the tube wall of this sound insulation plastic tube comprises skin and internal layer, forms a cavity layer between described skin and the described internal layer, and described cavity layer is a vacuum layer.
Further, be filled with one deck puigging in the described cavity layer, described puigging and internal layer adjacent and skin link together.
Further, described puigging is a kind of among foam layer, spongy layer, Sound-proof material layer, PU wave Sound-proof material layer or the rubber layer.
Further, described puigging is a kind of among polyester fibre sound-absorption layer, Cao Mu sound-absorption layer, hole wood sound-absorption layer or the recycled wood sound-absorption layer.
Further, it is characterized in that described skin is a kind of among polyvinyl plastics layer, the polypropylene plastics bed of material, polystyrene plastics layer or the polyvinyl chloride plastic bed of material.
Further, it is characterized in that described internal layer is a kind of among alkene plastics layer, the polypropylene plastics bed of material, polystyrene plastics layer or the polyvinyl chloride plastic bed of material.
Compared with prior art, sound insulation plastic tube of the present utility model is simple in structure, easy to process, has following beneficial technical effects: 1, be set to vacuum layer between the internal layer of plastic tube tube wall and the skin, and vacuum is not the medium of acoustic wave propagation, or between internal layer and skin the material layer with good sound absorption function is set, and can suck acoustic wave energy in a large number, for sound wave plays attenuation, sound-absorbing effect is good.2, the internal layer of tube wall and outer, good rigidly big by intensity, heat-resisting effect is good and can make by waterproof and dampproof plastic materials, is guaranteeing that plastic tube possesses the working life that time can also improve plastic tube in advance of sound absorption function.

Fig. 2 is the utility model sound insulation plastic tube embodiment two a structural representation.
Embodiment
Main thought of the present utility model is to solve the problem that the plastic tube that exists in the prior art does not possess the sound insulation function, below embodiment is carried out detailed description, but not as to qualification of the present utility model.
The utility model first embodiment as shown in Figure 1, the tube wall of plastic tube comprises skin 1 and internal layer 2, forms a cavity layer between skin 1 and the internal layer 2, is filled with one deck puigging 3 in the cavity layer, puigging 3 links together with skin 1 and internal layer 2.Be provided with a cavity layer in the tube wall of double-layer structure, by reaching desirable soundproof effect with being filled with one deck puigging 3 in the cavity layer, puigging 3 can be 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 a kind of among alkene plastics layer, the polypropylene plastics bed of material, polystyrene plastics layer or the polyvinyl chloride plastic bed of material.Certainly the puigging 3 in the present embodiment also can be a kind of among polyester fibre sound-absorption layer, Cao Mu sound-absorption layer, hole wood sound-absorption layer or the recycled wood sound-absorption layer, can reach good soundproof effect equally, the structure of skin 1 and internal layer 2 does not change, so be not repeated in this description at this.
Second embodiment of the present utility model as shown in Figure 2, the tube wall of plastic tube comprises skin 1 and internal layer 2, forms a cavity layer between skin 1 and the internal layer 2, cavity layer is a vacuum layer 4.Outer 1 is a kind of among polyvinyl plastics layer, the polypropylene plastics bed of material, polystyrene plastics layer or the polyvinyl chloride plastic bed of material, and internal layer 2 is a kind of among alkene plastics layer, the polypropylene plastics bed of material, polystyrene plastics layer or the polyvinyl chloride plastic bed of material.In the present embodiment, owing in the tube wall of double-layer structure, be provided with a cavity layer,, utilize the characteristics that vacuum can not conduct acoustic waves, reach desirable soundproof effect by layer that cavity layer is evacuated.
Certainly; the utility model can also have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
