Description

Silencing air pipe with composite material structure

Technical Field

The utility model relates to an air conditioner hush pipe technical field specifically is a amortization tuber pipe of combined material structure.

Background

The existing silencing air pipes are mainly pipe-diameter air pipes (the diameter of a circular air pipe is larger than 200mm, and the height of a rectangular air pipe is larger than 200 mm), are rough and crude in design structure and weak in silencing capability, and are difficult to meet the requirements of loads, spaces and noise levels of ordinary storey-height houses.

Therefore, how to design a silencing air pipe and how to improve the silencing effect of the fresh air system becomes a problem which needs to be solved urgently.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a amortization tuber pipe of combined material structure to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a amortization tuber pipe of combined material structure, includes the body, the body is by interior and outer in proper order including amortization layer, first soft layer, the soft layer of second and heat preservation, wherein the soft layer of second is hollow structure.

Preferably, the inner diameter of the pipe body is 75mm, and the outer diameter is 102mm.

Preferably, the sound attenuation layer is made of high-antibacterial non-woven fabric, and the thickness of the sound attenuation layer is mm.

Preferably, the first soft layer is made of soft plastics, a steel wire ring is embedded in the first soft layer, and the thickness of the first soft layer is 3mm.

Preferably, the second soft layer is made of soft plastics, and the thickness of the second soft layer is 4mm.

Preferably, the heat-insulating layer is made of glass wool or rubber and plastic sponge, and the thickness of the heat-insulating layer is 6mm.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model can be used for the air conditioning ventilation system with the inner pipe diameter of 50 mm-150 mm by arranging the multi-layer composite material to make the pipe body, the hollow plastic structures of the silencing layer made of non-woven fabric and the second soft layer have good silencing and sound insulating functions, the air supply speed can be improved to 6-12 m/s, and the silencing and heat-insulating effects are obvious; the utility model discloses matter is soft, does not need the on-spot secondary operation of installation, and the packing transports after being applicable to the customization of mill, and the connection pipe fitting that the cooperation matches, the installation is very simple and direct convenient.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. a pipe body; 2. a sound-deadening layer; 3. a first soft layer; 4. a second softer layer; 5. and (7) an insulating layer.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a amortization tuber pipe of combined material structure, includes body 1, body 1 is by interior and outer including amortization layer 2, first soft layer 3, second soft layer 4 and heat preservation 5 in proper order, and wherein second soft layer 4 is hollow structure. The pipe body 1 adopts a conventional pipe connecting piece, can be used after being connected with a ventilating air conditioner pipeline and equipment, and is very convenient to install.

In this embodiment, the inner diameter of the pipe body 1 is 72mm, and the outer diameter thereof is 102mm.

In this embodiment, noise damping layer 2 adopts high antibiotic non-woven fabrics to make, noise damping layer 2's thickness is 2mm, and the air permeability of non-woven fabrics is good, has avoided the production of secondary noise.

In this embodiment, first soft layer 3 adopts soft plastics to make, for example adopt the black that polyethylene expanded material made to inhale the sound PE cotton, because the porosity of the black material of inhaling the sound PE cotton itself, the audio frequency of middle, high frequency channel is inhaled the sound, can play in this structure and inhale sound, syllable-dividing effect, the thickness of first soft layer 3 is 3mm, there is the steel wire ring in first soft layer 3 inner chamber, and the steel wire ring is used for guaranteeing that the pipeline is circular as the skeleton, and the function of first soft layer 3 is moulding.

In this embodiment, the second soft layer 4 is made of soft plastic, the thickness of the second soft layer 4 is 4mm, and the second soft layer 4 is used for heat insulation and sound insulation and is formed by winding a double-sided aluminum foil and a steel wire; the steel wire is used as a framework to form a secondary sound absorption layer with a cavity structure between the sound insulation layer and the outer sleeve protective layer; the cavity structure of the second soft layer 4 is beneficial to improving the absorption of low frequency, thereby achieving the effect of noise reduction; the aluminum foil is used as an outer protective layer and is passivated to protect the sound insulation layer from being damaged by external force, so that the service life of the sound insulation layer is prolonged, and meanwhile, the aluminum foil is rainproof, fireproof and air-proof; the steel wire plays a supporting role as a framework, and the hollow plastic structure can reduce heat transfer.

The heat preservation 5 adopts glass cotton, compound silicate, polyurethane, rock wool, rubber and plastic sponge to make, the thickness of heat preservation 5 is 6mm, can effectually completely cut off the influence of ambient temperature to body 1 inside, increase of service life.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
