Description

Vent hose

Technical field

The utility model relates to a kind of flexible pipe, and more particularly, it relates to a kind of vent hose being applied to central air-conditioning system.

Background technique

At present, in ventilation duct technical field, the effect of the ventilation duct on central air-conditioner is by cold wind or hot blast introducing/extraction system, in this process, two requirements are proposed for ventilation duct: be first that material require possesses certain silencing function, to prevent from shaking the noise effect Environmental Conditions caused; Next is to air pipeline itself, should meet the needs for length in construction, namely can be scalable in certain length range.

At present, the material of ventilation duct on the market generally has two kinds: one to be the ventilation duct that the rigid material of hard supports, and such pipeline needs to carry out cutting and installing in erecting bed, and when after follow-up pipeline transformation, its length cannot change; The structure of what another kind of air pipeline material adopted is similar organ pipe, utilizes the form of elasticity flap, like this, by stretching or compressing organ pipeline portions, can adapt to the demand to length of pipe in constructing.The such as applying date is 2009.5.5, application number is disclose a kind of vent hose in the utility model patent (hereinafter referred to as documents 1) of 200920171916.8, it mainly utilizes bellows to solve the nonadjustable problem of vent hose length, and the material describing flexible pipe in its specification can adopt rubber, fire-resistant canvas etc.The flexibility of what in documents 1, the stretchability of flexible pipe mainly utilized is rubber, fire-resistant canvas material, go to set length of pipe according to the maximum value that may need, like this, when the length that pipeline needs is less than physical length, unnecessary pipeline is deposited between two flanges.

But, be similar to the demand not solving the noise reduction of ventilation duct in the same air pipeline of documents 1.The applying date is 2011.7.14, application number is disclose a kind of flexible metal in the patent of invention (hereinafter referred to as documents 2) of 201110196235.9 to fasten noise elimination vent hose, utilizes to be arranged on the inner corrugated hose with bloop and to complete noise reduction.

The problem that noise reduction and pipeline are flexible is solved in documents 2, but, itself there is certain manufacture difficulty in the structure of Sound eliminating soft pipe because Sound eliminating soft pipe itself to be spiral wrap inner at air pipeline, thus its diameter value is very little, and punch on such narrow tube, not only weaken the intensity of hush pipe, and, when after Sound eliminating soft pipe breakage, also may scratch outside flexible jacket, make vent hose lose sealing effect.

Model utility content

For the deficiency that prior art exists, the purpose of this utility model be to provide a kind of manufacture simple, noise reduction is reliable and have the vent hose of certain flexibility concurrently.

For achieving the above object, the utility model provides following technological scheme: a kind of vent hose, the flexible pipe comprising a pair adpting flange and be arranged between a pair adpting flange, described flexible pipe comprises resilient surrounding layer and liner, described surrounding layer and liner all surround tubular and two ends and described flange are fixed, and is filled with the foam material of sound-insulating between described surrounding layer and liner.

Further, be also provided with segmentation ring between described surrounding layer and liner, described flexible pipe is separated into some sections by described segmentation ring, and described surrounding layer and liner are fixed on the both sides of described segmentation ring.

Further, described surrounding layer adopts refractory fiber cloth.

Further, described foam material adopts polyethylene foam-material.

Further, described adpting flange includes flexible pipe connecting end, and described surrounding layer and liner are fixed on described flexible pipe connecting end outer surface by clip.

By adopting technique scheme, by filling the foam material with sound-insulating between surrounding layer and liner, realize sound insulation and the heat insulation function of vent hose; And, compared to prior art, the thermal insulating material be filled between surrounding layer and liner can be played a supporting role to stacking flexible pipe, like this, when the length of vent hose that pipeline needs is less than physical length, be deposited in that the flexible pipe between a pair adpting flange can not be too fast under the support of foam material aging and lose sealing.

Embodiment

Referring to figs. 1 through Fig. 3, the utility model vent hose is described further.

A kind of vent hose, as shown in Figure 1, the flexible pipe 2 including a pair adpting flange 1 and be arranged between two adpting flanges 1, wherein, flexible pipe 2 adopts to be made with certain flexible material.As shown in Figure 2, the foam material 23 that flexible pipe 2 includes surrounding layer 21, liner 22 and is filled between the two, surrounding layer 21 preferably adopts refractory fiber cloth, to improve the fire resistance rating of flexible pipe 2, because the common application of vent hose is air-conditioning or other refrigeration, uses as delivery line in heating device, thus foam material 23 can adopt sound insulation common on the market, nonflammable and have the foam material of certain thermal insulation property concurrently, be preferably polyethylene foam-material, this material not only can be incubated, sound insulation, and is nonflammable material.

For improving softness and the bulk strength of flexible pipe 2, some segmentation rings 4 are fixed by between inside and outside nested surrounding layer 21 and liner 22, the flexible pipe 2 of segmentation ring 4 just between a pair adpting flange 1 is some sections along the segmentation of its bearing of trend, and surrounding layer 21 and liner 22 are fixedly sewed together in the both sides of segmentation ring 4, like this, during filled with foaming material 23, be filled to the region between every two segmentation rings 4, can bend easily at segmentation ring 4 place flexible pipe 2, make the stacking convenient of flexible pipe 2 like this.

As shown in Figure 3, adpting flange 1 includes flexible pipe connecting end 11, external connection terminal 12 and draw-in groove 13, wherein flexible pipe connecting end 11 is fixedly connected with flexible pipe 2, during installation, liner 22 on flexible pipe 2 and surrounding layer 21 are placed on the outer wall of flexible pipe connecting end 11, clip 3 is also provided with in joint, flexible pipe 2 and flange 1 are fixed together by clip 3 reliably, draw-in groove 13 is arranged on the outer surface of flexible pipe connecting end 11, clip 3 snaps in draw-in groove 13 when mounted, to increase for the attachment force between flexible pipe 2 and flange 1.The face area of external connection terminal 12 is greater than the size of flexible pipe connecting end 11, like this, when vent hose is connected on extraneous pipeline, the end face of external connection terminal 12 can be arranged some threaded fasteners or other riveting parts, like this vent hose is sealingly connected to required occasion.

The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
