Abstract
The utility model relates to a double-layer spiral heat-insulating air pipe device, which comprises an air pipe and a protective pipe body sheathed on the periphery of the air pipe, and is characterized in that heat insulating material is filled between the air pipe and the protective pipe body, an annular rubber ring positioned between the air pipe and the protective pipe body is arranged at an end opening of the device, and the inner and the outer sides of the annular rubber ring are locked and positioned through radial screws of the protective pipe body or the air pipe. The double-layer spiral heat-insulating air pipe device has the advantages of simple structure, convenient production and installation and good heat preservation and insulation effects.
Description
Technical field
The utility model relates to a kind of double-layer spiral thermal insulation wind pipe device.
Background technique
Delivery pipe system for transporting cold wind or hot blast, common problem is the joint at ajutage and valve, the bad problem of sealing appears easily, as the central air-conditioning system supply air system in, the joint of airduct and flow control valve, because sealing can not get guaranteeing, occur easily leaking or energy loss, air-flow blows to interlayer and heat-preservation cotton is blown out influences environment.
Summary of the invention
The purpose of this utility model is to provide a kind of double-layer spiral thermal insulation wind pipe device, and this device construction is simple, be convenient to produce and install, and the insulation insulation effect is good.
The technical solution of the utility model is: a kind of double-layer spiral thermal insulation wind pipe device, comprise airduct and the protection body that is sheathed on the airduct periphery, it is characterized in that: be filled with thermal insulating material between described airduct and the protection body, its port is provided with the ring apron between airduct and protection body, and the interior outside of described ring apron is through the radial screw locking and positioning of protection body or airduct.
Advantage of the present utility model is: simple structure, financial cost is low, be convenient to produce install, and the insulation insulation effect is good, can effectively prevent the flow leakage problem of airduct and valve joint.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of double-layer spiral thermal insulation wind pipe device, comprise airduct 1 and the protection body 2 that is sheathed on the airduct periphery, it is characterized in that: be filled with thermal insulating material 3 between described airduct and the protection body, its port is provided with the ring apron 4 between airduct and protection body, and the interior outside of described ring apron is through radial screw 5 locking and positioning of protection body or airduct.
