Abstract
The utility model provides an air supply duct, belongs to mechanical technical field. It has ventilation holes to distribute below the radial central line of pipeline, does not have ventilation holes more than the radial central line of pipeline, and the pipeline that does not have ventilation holes has ventilation holes's pipeline to be equipped with flange towards ground direction, pipeline both ends towards the ceiling, connects the fan blade that opens and shuts among the ventilation holes, and ventilation holes can be closed to the fan blade that opens and shuts. The utility model has the advantages that: the air supply direction can be directional, in time blows off the gas to harmful to the human body, blow to the place that needs the new trend, if give people and send fresh air and so on here, adopt the air supply of circular ventilation holes eye can reach the even effect of air supply. Connect the fan blade that opens and shuts among the ventilation holes, under the condition that does not need wind, close ventilation holes.
Description
Technical field
The utility model relates to a kind of supply air duct, belongs to field of mechanical technique.
Background technique
There is more harmful material in laboratory, need to arrange air draft.And also need while arranging air draft to supplement new wind to laboratory.Existing scheme mends new wind for adopting independent air blowing opening, and this kind of scheme because air port is not continuous layout, causes the not all even air supply direction non-directional of new wind supplemented when mending wind.And do without the air port of this kind of form during furred ceiling laboratory attractive in appearance not.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of supply air duct.
A kind of supply air duct, below the radial centre lines of pipeline, be distributed with wind pushing hole, more than the radial centre lines of pipeline, do not have wind pushing hole, do not have the pipeline of wind pushing hole towards ceiling board, have the pipeline of wind pushing hole towards direction, ground, pipe ends is provided with adpting flange.
Or in 45 degree of pipeline section side, be distributed with wind pushing hole, have the pipeline of wind pushing hole towards plan air supply direction.
The shape of wind pushing hole has circle, ellipse or polygonal.
Connect air-supply eyelet in circular wind pushing hole, air-supply eyelet has support, is supported for trilobal cross, four blade profiles or five blade profiles.
Connect folding fan blade in wind pushing hole, folding fan blade can close wind pushing hole.
The utility model has the advantages that: air supply direction can be directed, dispels harmful gas in time, blow to the place needing new wind, as sent fresh air etc. here to people, adopting the air-supply of circular air-supply eyelet can reach the uniform effect of air-supply.Connecting folding fan blade in wind pushing hole, when not needing wind, closing wind pushing hole.
The air-supply of circular air-supply eyelet can reduce wind speed than existing air-supply scheme, reduces noise.Circular air-supply eyelet air-supply is simultaneously when doing without furred ceiling laboratory, and air-supply eyelet can increase the aesthetic in laboratory.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by referring to detailed description below, more completely can understand the utility model better and easily learn wherein many adjoint advantages, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model, for explaining the utility model, does not form improper restriction of the present utility model, as schemed wherein:

Fig. 3 is wind pushing hole ocular structure schematic diagram of the present utility model.
Fig. 4 is two figure of structural representation of the present utility model.
Fig. 5 is wind pushing hole ocular structure schematic diagram of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment
Obviously, those skilled in the art belong to protection domain of the present utility model based on the many modifications and variations that aim of the present utility model is done.
Embodiment 1: as shown in Figure 1 and Figure 2, a kind of supply air duct, and pipeline 1 has wind pushing hole 2, the shape of wind pushing hole 2 has circle, oval and polygonal, and wind pushing hole 2 is evenly distributed on the side of pipeline 1, connect folding fan blade in wind pushing hole, folding fan blade can close wind pushing hole.
As shown in Figure 5, have wind pushing hole 2 at 45 degree, the cross section directional spreding of the side of pipeline 1, have the pipeline of wind pushing hole 2 towards plan air supply direction, directed air-supply, pipeline 1 two ends are provided with adpting flange, for the connection between pipeline 1.Supply air duct adopts high-quality cold rolled sheet, twists, sprays and form, and opens air-supply porosity according to the requirement conversion pipe diameter of room, laboratory rate of ventilation and pipeline airduct.
Embodiment 2: as shown in Figure 4, a kind of supply air duct, below the radial centre lines of pipeline 1, be distributed with wind pushing hole 2, more than the radial centre lines of pipeline 1, there is no wind pushing hole, there is no the pipeline of wind pushing hole towards ceiling board, have the pipeline of wind pushing hole 2 towards direction, ground, directed air-supply
Embodiment 3: a kind of supply air duct, and other structures, as described in above-described embodiment, connect air-supply eyelet 3 in circular wind pushing hole 2, and as shown in Figure 3, air-supply eyelet 3 has support 4, and supporting 4 is trilobal cross, four blade profiles or five blade profiles.
As mentioned above, embodiment of the present utility model is explained, but as long as do not depart from inventive point of the present utility model in fact and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, such variation is also all included within protection domain of the present utility model.
