Abstract
The utility model discloses an improved sheet metal air conduit, which comprises a conduit body, wherein the conduit body comprises an inner conduit and an outer conduit, the outer conduit is sleeved outside the inner conduit, and a connector is arranged on the end portion of the outer conduit. The improved sheet metal air conduit is characterized in that a baffle plate is arranged in the conduit body, one end of the baffle plate extends outside the conduit body, two layers of insulating layers are arranged between the inner conduit and the outer conduit, and a fireproof layer is arranged between the two layers of insulating layers. The improved sheet metal air conduit has the advantages of reasonable structure, excellent use effect and strong function.
Description
Technical field
The present invention relates to a kind of ventilating duct, relate in particular to a kind of improved panel beating ventilating duct.
Background technology
Existing production department or the employed ventilating duct of large-scale processing space, all simpler and cruder, all be to adopt simple iron sheet welding to form.This ventilating duct simple in structure reaches certain pressure or airflow direction and changes in pipeline, all can cause interior its of pipeline to recharge, alter the phenomenon of flavor, can be to environment.In addition, existing panel beating ventilating duct, function singleness, result of use is bad, can not satisfy user demand.Therefore, should provide a kind of new technical scheme to address the above problem.
Summary of the invention
The objective of the invention is: for above-mentioned deficiency, provide a kind of rational in infrastructure, result of use is good functional strong improved panel beating ventilating duct.
For achieving the above object, the technical solution used in the present invention is:
A kind of improved panel beating ventilating duct, comprise pipeline body, the outer tube that described pipeline body comprises inner tube and is sheathed on interior tube outside, the end of described outer tube is provided with connector, the inside of described pipeline body is provided with baffle plate, one end of described baffle plate stretches out outside the pipeline body, is provided with two-layer insulation layer between the described inner and outer tubes, is provided with fireprotection layer between the described two-layer insulation layer.
The bottom of described baffle plate is provided with handle.
Described connector is adpting flange.
The thickness of described insulation layer is 10-20mm.
The thickness of described fireprotection layer is 5-25mm.
A kind of improved panel beating ventilating duct of the present invention, inside at pipeline body is provided with baffle plate, one end of baffle plate stretches out the outside of pipeline body, when reaching certain pressure or airflow direction in the ventilating duct and change, just baffle plate can be pushed to ventilating duct is sealed, prevent that the phenomenon of flavor from appearring recharging, altering in pipe interior gas, can be to environment.Between inner and outer tubes, be provided with two-layer insulation layer, be provided with fireprotection layer between the two-layer insulation layer, strengthened heat insulating ability and the refractoriness of panel beating ventilating duct of the present invention, improved its operating efficiency.
Advantage of the present invention is: rational in infrastructure, result of use good, functional strong.
