Abstract

The utility model discloses a noise-reduction and heat-insulation canvas soft connecting pipe, and relates to the technical field of pipe fittings, in order to solve the technical problems of noise reduction and heat insulation. The pipe wall of the soft connecting pipe is provided with an inner layer and an outer layer; an annular noise-reduction and heat-insulation cavities which surround an axis for one circle circumferentially are formed between the inner layer and the outer layer axially of the pipe wall; each noise-reduction and heat-insulation cavity protrudes inwards in a wave peak mode, and is filled with noise-reduction and heat-insulation materials. The soft connecting pipe provided by the utility model is suitable for the soft connection between a blowout device and a hard air pipe.

Description

The canvas hose connector that noise reduction is heat insulation

Technical field

The utility model relates to the pipe fitting technology, particularly relates to the technology of the heat insulation canvas hose connector of a kind of noise reduction.

Background technique

In air-conditioning system, usually adopt individual layer canvas hose connector to realize being flexible coupling between equipment and the airduct, this kind Placement has following defective: can reserve very large span when 1) the canvas hose connector is installed, during fan operation, because the variation of air quantity, canvas webmaster place can produce very large noise, because canvas is very thin, the noise of blower fan inside also easily directly spreads out of by the canvas hose connector simultaneously; 2) canvas hose connector itself is very thin, and thermal insulation property is relatively poor, and the wind that blower fan blows out can lose more heat during by canvas webmaster place.

The model utility content

For the defective that exists in the above-mentioned prior art, it is low that technical problem to be solved in the utility model provides a kind of noise, can reduce the heat insulation canvas hose connector of noise reduction of heat loss.

In order to solve the problems of the technologies described above, the canvas hose connector that a kind of noise reduction provided by the utility model is heat insulation, it is characterized in that: the tube wall of this hose connector has inside and outside two-layer, between its tube wall internal and external layer vertically the interval be formed with along the annular noise reduction heat-insulation chamber of circumferential hoop around its axis one circle;

Each noise reduction heat-insulation chamber all inside crest shape protrudes, and is filled with the noise reduction thermal barrier.

The canvas hose connector that the noise reduction that the utility model provides is heat insulation, because the tube wall of this hose connector has inside and outside two-layer, between the tube wall internal and external layer, be arranged at intervals with vertically annular noise reduction heat-insulation chamber, in the noise reduction heat-insulation chamber, be filled with the noise reduction thermal barrier, effectively noise reduction and heat leaks, the mode that the while interval arranges the noise reduction heat-insulation chamber has kept the flexible extensions amount, therefore when having kept soft connection speciality, also with the heat insulation characteristics of noise reduction.

Description of drawings

Fig. 1 is the tube wall sectional drawing of the heat insulation canvas hose connector of the utility model embodiment's noise reduction;

Fig. 2 is the three-dimensional view of the heat insulation canvas hose connector of the utility model embodiment's noise reduction.

Embodiment

Below in conjunction with description of drawings embodiment of the present utility model is described in further detail, but the present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar variation thereof all should be listed protection domain of the present utility model in.

Such as Fig. 1-shown in Figure 2, the canvas hose connector that a kind of noise reduction that the utility model embodiment provides is heat insulation, it is characterized in that: the tube wall of this hose connector has inside and outside two-layer, between its tube wall internal layer 2 and the tube wall skin 1 vertically the interval be formed with the annular noise reduction heat-insulation chamber that encloses around its axis one along circumferential hoop;

Each noise reduction heat-insulation chamber all inside crest shape protrudes, and is filled with noise reduction thermal barrier 3.

Among the utility model embodiment, described tube wall internal layer 2 and tube wall skin 1 are canvas layer, and described noise reduction thermal barrier 3 is rock wools.

The utility model embodiment is suitable as being flexible coupling between blast apparatus and the hard airduct, when the wind that blast apparatus blows out is advanced in the utility model embodiment's canvas hose connector, noise reduction thermal barrier in each noise reduction heat-insulation chamber can effectively reduce leaking of noise and heat, and the interval arranges the mode of noise reduction heat-insulation chamber so that kept flexible extendable room between each noise reduction heat-insulation chamber simultaneously.

Claims

1. canvas hose connector that noise reduction is heat insulation is characterized in that: the tube wall of this hose connector has inside and outside two-layer, between its tube wall internal and external layer vertically the interval be formed with along the annular noise reduction heat-insulation chamber of circumferential hoop around its axis one circle;
