Abstract
The utility model provides a pipe body for wind channel, which is characterized in that the pipe body 1 is formed by combining an inner pipe body 3 which is made of a polyethylene high foaming body, and a protective layer 2 which is coated on the outer wall of the inner pipe body 3. The utility model has the advantages of convenient processing, convenient construction, low manufacture cost, good strength of the pipe body, good heat insulation performance and good thermal insulation performance.
Description
The utility model relates to ventilation plant, is applied to the body on the ventilation flue more precisely.
Common air channel is three-decker with body, and promptly galvanized iron sheet or glass fibre reinforced plastics is as supporting layer, is coated on supporting layer outer thermal insulation layer and the outmost protective layer made by rock wool, polyurethane foam material.Such air channel is that manufacture cost is higher with the shortcoming of body.
The purpose of this utility model provides a kind of easy for installation, uses the pipe structure of reliable and low cost of manufacture.
Figure of description is a structural representation of the present utility model;
1-body in the accompanying drawing, 2-protective layer, 3-interior tube body.
As shown in the figure, body 1 provided by the utility model is by PEF foam occurred frequently (PEF) The interior tube body 3 of making and protective layer 2 compound the making that are coated on interior tube body 3 outer walls. Body 1 Shape of cross section can make as required square, rectangle or circle. Protective layer 2 can be selected Aluminium platinum paper or PAP material are made.
The manufacturing of interior tube body 3 in the utility model can be cut out PEF sheet material and be slit into required form by design, utilize the good hot melt property of PEF, melts the interface of sheet material with electric heating apparatus, through butt joint, pressurization, fixedly 3-5 promptly connects moulding after second.Certainly also available glue implements to paste interface.Can be made into elbow, reducing of circle, square, rectangular body and various angles etc. with said method.
The utility model has the advantages that: processing is executed down and is made things convenient for, and it is low to manufacture cost, and (only be other air channel body costs 1/10) has the intensity and the heat preservation and insulation of good body.
Claims (3)
