Abstract
The utility model relates to a connecting device for the aluminum alloy heat insulation flange of the complex wind pipe and includes a flange, a corner and a flange quickset; wherein, the flange includes an inner board and an outer board; the relative surfaces on the inner board and the outer board near the outer ends are provided with insertion flute that are internally provided with insulation strips to connect the inner board and the outer board in parallel; the outer end of the outer board is connected with the insertion strips; the corner is a right triangle that is connected with three vertical rectangle planes; an L shape insertion plate is parallel with one side of the corner and are connected with the other two sides; the two sides of the flange quickset are provided with bent edges that are folded inward and are matched with the connecting insertion flute on the flange outer board. The utility model has the advantages of convenience due to the assembly that only needs insertion, easy production due to most of the components of sheets, good heat insulation as well as avoiding condensation water at the connecting part due to the heat insulation strips connected between the inner board and the outer board, as well as good sealing performance due to unified quickset and sealing pads between the two end faces of the flange.
Description
Technical field
The utility model relates to a kind of heat insulation flange connecting apparatus of aluminum alloy that is used for composite air duct.
Two kinds of main PVC adpting flange of form of flanges that composite air duct connection is at present adopted and angle steel adpting flanges.The not enough point of angle steel adpting flange: sealing is poor, and leakage rate is big; Thermal insulation is poor, is easy to generate condensed water; Install and make slowly.
Background technique
The not enough point of PVC adpting flange: leakage rate is big; Fireproof performance is relatively poor, and using has narrow limitation; Intensity is lower.
Summary of the invention
The purpose of this utility model just provides a kind of sealing and good, the easy installation of thermal insulation, the higher heat insulation flange connecting apparatus of the aluminum alloy that is used for composite air duct of intensity.
The technical solution of the utility model is: comprise flange, turning, flange cutting, described flange comprises inner panel and outside plate, near on the opposing side of outer end relative slot is arranged in inner and outer plates, heat insulation plaster is arranged in this slot, the connection slot is arranged in the outer end of outside plate with the parallel connection of inner and outer plates; Described turning is the right angle body that is connected by three orthogonal rectangular flats, also has a L type plate parallel with the one side at turning, and is connected with other two sides; There is the crimp of inside doubling on the both sides that described flange is transplanted a cutting, and match with the slot that is connected on the flange outside plate.
Between described flange inner and outer plates, the Saw blade parallel with its outer end arranged.
Also comprise the Stamping Steel Ribbon between end face of flange.
Described flange inner and outer plates and flange are transplanted a cutting and are aluminium alloy extrusions; Described heat insulation plaster is the section bar that modified plastics is made; Described turning is made by PCV.
The utility model advantage is: only needs to peg graft and can finish installation, and very convenient; Most of parts all are made of section bar, are easy to produce; Connected by heat insulation plaster between the inner and outer plates, thermal insulation is good, avoids the joint to produce condensed water; Connect by unified cutting between the end face of flange and accompany sealing gasket, make it have good sealing.The utility model adopts aluminum alloy material in addition, and its fire retardancy is better than PVC.
Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings
Fig. 1 is an end face of flange structural representation of the present utility model;
Fig. 2 is the utility model turning end-face structure schematic representation;
Fig. 3 is the schematic representation of the solid of cutting of the present utility model;
Fig. 4 is the general structure sectional drawing after the utility model connects;
Fig. 5 is the schematic representation after the airduct end face is provided with flange.
Embodiment
Referring to Fig. 1, flange A of the present utility model is made of top outside plate 1 and following inner panel 2 and the heat insulation plaster between them 3, and insert in the relative slot 4 of inner and outer plates one end inner face at the two ends of heat insulation plaster 3.There is the slot 11 of connection outside, end at outside plate 1.Inner and outer plates 2 and 1 constitutes by aluminium alloy extrusions, and heat insulation plaster 3 is the modified plastics section bar.At the inner and outer plates opposing side sawtooth striped 5 parallel with end face arranged all, its effect is to make more firm that inner and outer plates combines with wind pipe wall between them.
When mounting flange, according to the inner and outer plates 2,1 of the length intercepting flange of four walls of the end face of airduct and the length of heat insulation plaster 3.Because the FL flange length on four limits of airduct port can only be as the criterion with inner face length, so (referring to Fig. 5) vacated at its four angles, so must be installed on four angles of each airduct end face with turning shown in Figure 26, so the length of side in a front 61 at turning is identical with the thickness of wind pipe wall 7, and front 61 will be longer than in its L shaped plate 62 two ends, and its part that grows is inserted between the end face of flange heat insulation plaster 3 and wind pipe wall 7.
Referring to Fig. 3, this is that flange is transplanted a cutting 8 structural representation, and its both sides all be the crimp 81 of inside doubling, in the connection slot 11 of two flange outside plate ends that each crimp 81 insertion is docking together, with two flange A link together (seeing also Fig. 4).
The general structure of the present utility model that links together has been shown among Fig. 4, between the end face of the two flange A that dock, has been added with sealing gasket 9, to improve sealing.
Express the structure that airduct end face of the present utility model has been installed among Fig. 5, respectively connect a cover flange A on four limits, on four angles, then replenish so that whole end face is concordant, complete by the utility model turning 6.
