Abstract
The present invention provides a new-type air pipe. It is characterized by that the frame material can be made into the form of air pipe, said frame material has a certain thickness (for example 30 mm) and can be made into hollow from, the inner surface and outer surface of said frame material are respectively coated with a layer of airtight material, said two layers of airtight material and hollow frame structure are formed into the invented heat-insulating air pipe.
Description
Technical field the invention belongs to the airduct technical field
The background technique airduct is mainly used in the ventilation and air conditioning system in the building, and airduct commonly used mainly contains three major types, and the first kind is the conventional thin steel plate wind pipe, is spliced into the airduct main body with sheet metal, covers thermal insulating material outward; Second class is a glass fibre reinforced plastic blast pipe, makes with glass fibre reinforced plastic material integral body; The 3rd class is the aluminium foil hvac duct; its sheet material is " sandwich " formula structure; it promptly is core with the thermal insulating material; protective materials such as clad aluminum foil, aluminium foil folder muscle kraft paper constitute, and common blast pipe board is aluminium foil composite phenol formaldehyde foam plate, aluminium foil composite polyurethane foam plate, aluminium foil composite extrusion polystyrene foamed boards etc.
Summary of the invention the present invention " Hollow blast pipe " is a kind of airduct of newtype, it is characterized in that: frame material is encircled into the airduct shape, frame material has certain thickness (for example 30 millimeters thickness) and makes hollow form, internal surface and outer surface at frame material cover one deck gastight material respectively, and inside and outside two layers of gastight material add that the frame structure of hollow has constituted with the thermal insulation wind pipe of air blanketing as main heat preserving mode.
Gastight material can be that rigid material is made, and for example makes with galvanized sheet iron; Also can make with flexible material, for example make with aluminium foil composite glass fiber cloth, when adopting flexible material, patented technology also comprises with making structure reaches airtight purpose.
Hollow blast pipe can have three kinds of citation forms: first kind of form is inside and outside each one deck flexible airtight material, therebetween hollow frame material; Second kind of form is inside and outside two layers of rigidity gastight material, therebetween hollow frame material; The third form is one deck rigid material and one deck flexible material, therebetween hollow frame material.
When the hollow airduct adopts first kind of form, one end that each can be saved airduct is sewed together with the flexible material of flexible material with inner and outer surface, the other end flexible material at airduct is fixed on the framework of Hollow blast pipe, realizes flexible material tightening on the airduct surface by this way.Certainly, also two ends of flexible material can be fixed on the framework, realize flexible material tightening on the airduct surface with this.
When the hollow airduct adopted first kind of form, the plug-in type connecting structure was adopted in connecting between airduct and the airduct.
Description of drawings Fig. 1: rectangular hollow airduct structure drawing in side sectional elevation
This rectangular hollow airduct adopts flexible airtight material as inner and outer surface, and flexible material 1 is the outer surface of airduct, and joint 2 is the joint of making of flexible material 1.Member 3 is vertical strong frame of airduct, member 4 for vertically flat be used for the stayed surface flexible material, it connects mutually with the transverse frame of airduct two ends, member 3, member 4 have constituted the hollow frame of airduct with the transverse frame of airduct two ends.Flexible material 5 is the internal surface of airduct, and joint 6 is the joint of making of flexible material 5.Air blanketing between member 1 and the member 2 provides excellent thermal insulation property for airduct.The thickness of adjusting hollow frame can be adjusted the thermal insulation property of airduct easily.
Fig. 2: the rectangular frame airduct vertically connects part sectioned view
Outer surface flexible airtight material 1, transverse frame 7, inner surface flexible airtight material 5, vertically flat 4 The coupling compoonent 13 of inner surface flexible material 5 and transverse frame, outer surface flexible material 1 and transverse frame Coupling compoonent 8 has consisted of the local longitudinal profile of airduct in left side together; Flexible airtight material 9, transverse frame 10, vertically consisted of together the local longitudinal profile of airduct on right side for flat 11, the connection of left and right sides airduct Adopt insert structure in the framework, be fixed by member 12 that (for the airduct of level, member 12 is not must The member of wanting). This blast connection makes the air approach outside joint flows to airduct in the airduct longer, simultaneously warp Crossing two places has the contact position of position member 9 with member 1 contact position and member 9 and the member 5 of sealing effectiveness, Member 10 is elastomeric element simultaneously, and therefore, sealing effectiveness is good. The airduct very high to seal request, also Can adopt in the joint additional seal approach.
If adopt circular hollow frame, can make circular Hollow blast pipe.
