Description
Technical field
The utility model is related to airduct elbow field, and in particular to a kind of flow-guiding type muffling air duct elbow.
Background technology
With the development of science and technology, the improvement of people's living standards, the requirement to the good acoustic environment of creation is more urgent,
Having more comfortable, quiet environment then is required to the building such as house, hospital, hotel, office building.In ventilating system, airduct conveying
Noise is one of main noise source, especially airduct corner, due to wind direction suddenly change, and wind hits pipeline, produces bigger
Noise.Existing technological means is usually to use bend muffler.
But the bend muffler on existing market is once-forming, does not adapt to actual operating mode often, and soundproof effect is big
Give a discount.
Utility model content
(1) technical problem solved
The utility model aims to overcome that the shortcoming of above-mentioned prior art, and there is provided a kind of flow-guiding type muffling air duct is curved
Head, can be adjusted for actual condition.
(2) technical scheme
A kind of flow-guiding type muffling air duct elbow, including body, flow deflector and rotating shaft；The body is Split type structure, including
Left body and right body, are connected together；The left body and right body are correspondingly arranged on fixed seat；The flow deflector is arranged on pipe
In vivo；Described flow deflector connection rotating shaft one end；The body is provided with through hole；The other end of the rotating shaft is arranged on through through hole
Outside body；The flow deflector both sides are additionally provided with gag lever post.
It is preferred that, the rotating shaft outer end sets crown cap.
It is preferred that, the rotating shaft and body junction are provided with sealing ring.
It is preferred that, the flow deflector is arc.
It is preferred that, the fixed seat is uniformly arranged on body.
(3) beneficial effect
The utility model provides a kind of flow-guiding type muffling air duct elbow, and elbow is using splicing snap-on design, easy cleaning
Change；And rotatable flow deflector is provided with inside elbow, it is convenient that flow deflector is adjusted according to actual condition, it is ensured that to disappear
Sound effective value.
Brief description of the drawings
In order to illustrate more clearly of the technical scheme of the utility model embodiment, make required for being described below to embodiment
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only of the present utility model, protect some realities
Example is applied, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to these accompanying drawings
Obtain other accompanying drawings.
Fig. 1 is front view of the present utility model；
Fig. 2 is the view in A-A directions in Fig. 1.
In accompanying drawing, the list of parts representated by each label is as follows：
1- bodys, the left bodys of 101-, the right bodys of 102-, 2- fixed seats, 3- flow deflectors, 4- rotating shafts, 401- top caps, 402- is close
Seal, 5- gag lever posts.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The all other embodiment obtained, belongs to the scope of the utility model protection.
Referring to shown in Fig. 1, Fig. 2, a kind of flow-guiding type muffling air duct elbow, including body 1, flow deflector 3 and rotating shaft 4；Body 1
For Split type structure, including left body 101 and right body 102, it is connected together；The corresponding uniform welding of left body 101 and right body 102
There is fixed seat 2, fastened body 1 by screw；Flow deflector 3 is arranged in body 1；Flow deflector 3 is arc, with elbow radian pair
Should；The one end of 3 connection rotating shaft of flow deflector 4；Body 1 is machined with through hole；The other end of rotating shaft 4 is arranged on outside body 1 through through hole,
So rotating shaft 4 is the angle of adjustable flow deflector 3, to adapt to different actual conditions.The outer end of rotating shaft 4 sets crown cap
401, convenient force.Rotating shaft 4 and the junction of body 1 are provided with sealing ring 402, play Anti-air-leakage, and increase friction, prevent
Flow deflector is shifted after adjustment angle.The both sides of flow deflector 3 are additionally provided with gag lever post 5, and gag lever post 5 is welded on the inwall of body 1, can be right
The rotational angle of flow deflector 3 is limited, and prevents flow deflector 3 from crossing transfer position under wind-force effect.
When in use, flow deflector 3 is adjusted the utility model according to actual condition by user, to realize optimal noise reduction
Effect.
In the description of this specification, the description of reference term " one embodiment ", " example ", " specific example " etc. means
With reference to the specific features that the embodiment or example are described, structure, material live feature be contained in it is of the present utility model at least one
