Abstract
The utility model discloses a kind of airduct, comprise pipe fitting body, pipe fitting body is sewed up by zinc coated sheet or Stainless Sheet Steel band coiling seaming; form occlusion limit; lock joint is outside pipe, inner level and smooth, and airduct body one end is outwards provided with or beading protruding inwards; The invention also discloses a kind of airduct bend connecting fitting, Y type link, circle reducing link and skew T link, each link is outwards connected by some suitable link bodies and forms, and each link body has occlusion limit as above and beading.This airduct and link tightness thereof are better, and body has air tight, and the feature such as not leak out, add the bearing strength of pipe fitting, the connection between airduct and link is more firm, can meet the needs of different occasion.
Description
Technical field
The utility model relates to the technical field of ventilation apparatus, particularly a kind of airduct and link thereof.
Background technique
Airduct is the pipe-line system for air conveying and distribution.By sectional shape, airduct can be divided into circular duct, rectangular air duct, and oblate airduct etc. are multiple, and wherein circular duct resistance is minimum, height dimension is maximum, makes simple, so application is based on circular duct.Airduct is mainly used in: (1) blows, and comprises ventilation, and as sent fresh wind and exhaust, this wide range, as factory floor, production site air, needs outside discharge chamber because harmful gas produces, need again outdoor air to be delivered to indoor.At this moment will the large and airflow pipe that pressure is little of use traffic; (2) send cold wind, modal is the pipeline of central air-conditioner, and this pipeline needs to add thermal insulating material.Spiral duct interiorly can paste thermal insulating material, and appearance be it seems attractive in appearance; (3) cooking-fume discharging, the kitchen in restaurant, restaurant, hotel all has a large amount of oil smoke to produce, and needs to discharge, and uses circular airduct to be exactly oil smoke chimney; (4) dedusting, some a lot of dust in plant produced workshop, needs special dust removal apparatus; (5) transmitting bulk material, in the production process of some factory, the use airduct cost as expandable plastic grain and so on needing to carry loose particle, particularly proportion little is low, effective.Along with the extensive use of airduct, convenience, tightness and the intensity that airduct is installed is had higher requirement.
Model utility content
The purpose of this utility model is to provide a kind of easy to connect, and tightness is good, the airduct that intensity is high and link thereof.
For achieving the above object, the technological scheme that the utility model provides is: a kind of airduct, comprise pipe fitting body, described pipe fitting body is sewed up by zinc coated sheet or Stainless Sheet Steel band coiling seaming, form occlusion limit, lock joint is outside pipe, inner level and smooth, and described airduct body one end is outwards provided with or beading protruding inwards.
The utility model additionally provides a kind of air pipe connector, be connected with airduct pipe fitting body, described link can be bend connecting fitting, and described bend connecting fitting is outwards connected by some suitable link bodies and forms, and link body has occlusion limit as above and beading.
Preferably, described link can also be Y type link.
Preferably, described link can also be circle reducing link.
Preferably, described link can also be skew T link.
A technological scheme tool in technique scheme has the following advantages or beneficial effect: this airduct and link thereof are provided with occlusion limit, the tightness of airduct and link is better, body has air tight, the feature such as not leak out, add the bearing strength of pipe fitting, can strengthen the dynamics of bearing is 300% simultaneously; Be provided with beading, the connection between airduct and link is more firm, adds intensity, serves spacing effect, improves tightness; Be provided with many moneys link, the needs of different occasion can be met.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, simple introduction is done below by the accompanying drawing used required in embodiment or description of the prior art, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Embodiment
Below by specific embodiment, the utility model is further described.
A kind of airduct of embodiment, comprise pipe fitting body, pipe fitting body is sewed up by zinc coated sheet or Stainless Sheet Steel band coiling seaming, forms occlusion limit, lock joint is outside pipe, inner level and smooth, this occlusion limit that this airduct is arranged, airduct tightness is better, body has air tight, the feature such as not leak out, add the bearing strength of pipe fitting, can strengthen the dynamics of bearing is 300% simultaneously.Pipe fitting body one end is outwards provided with or beading protruding inwards, and this beading of setting, the connection between airduct and link is more firm, adds intensity, serves spacing effect, improves tightness.
As shown in Figure 1, a kind of air pipe connector of embodiment, be connected with airduct pipe fitting body, link can be bend connecting fitting, bend connecting fitting is outwards connected by five suitable link bodies 1 and forms, and each link body 1 has occlusion limit 2 as above, and the link body end be connected with pipe fitting body is provided with spacing beading 3, beading 3 improves the tightness that pipe fitting connects, and adds join strength.
As shown in Figure 2, link can also be Y type link, and Y type link is outwards connected by three suitable link bodies 1 and forms, and each link body 1 itself has occlusion limit 2, and the link body end be connected with pipe fitting body is provided with beading 3.
As shown in Figure 3, link can also be circle reducing link, circle reducing link is outwards connected by three suitable link bodies 1 and forms, and each link body 1 self has occlusion limit 2, and the link body 1 at the two ends that are connected with pipe fitting body is provided with beading 3.
As shown in Figure 4, link can also be skew T link, and skew T link is outwards connected by four suitable link bodies 1 and forms, and each link body 1 has occlusion limit 2, and the link body end be connected with pipe fitting body is provided with beading 3.
The present embodiment is provided with many moneys link, can meet the needs of different occasion.It should be pointed out that link can also be four-way link, five-way connecting piece etc., occlusion limit and beading can be set equally, all should belong to protection domain of the present utility model.
Apply specific embodiment herein to set forth principle of the present utility model and mode of execution, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.The above is only preferred implementation of the present utility model, should be understood that, due to the finiteness of literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, under the prerequisite not departing from the utility model principle, some improvement, retouching or change can also be made, also above-mentioned technical characteristics can be combined by rights; These improve retouching, change or combination, or the design of model utility and technological scheme are directly applied to other occasion without improving, and all should be considered as protection domain of the present utility model.
