Abstract

The utility model provides a connection mechanism of an electro-thermal tube and a flange and relates to electric heating components. The connection mechanism includes a flange and an electro-thermal tube. A fixing hole used for fixing the electro-thermal tube is arranged in the flange. An end of the electro-thermal tube is inserted into the fixing hole. The fixing hole is a curling hole. An outer hole opening of the curling hole connects with the tube wall of the electro-thermal tube in a welding manner. The utility model provides the connection mechanism of the electro-thermal tube and the flange. The connection mechanism of the electro-thermal tube and the flange has characteristics of simple structure, reasonable design, high sealing performance and good mechanical strength. And the electro-thermal tube can be fixed firmly and the fixing point has high precision.

Description

The syndeton of a kind of electrothermal tube and flange
Technical field
The utility model relates to electric heating element, specifically is the syndeton about a kind of electrothermal tube and flange.
Background technology
Electrothermal tube on the existing electrical equipment with heating function fixing has plenty of electrothermal tube is fixed to earlier on the flange and electrothermal tube is fixed on the heating position of electrical equipment through flange then again.Electrothermal tube is fixed on the mode on the flange, generally is on flange, to hold fixing hole successfully, and electrothermal tube passes that useful riveted way is fixedly connected behind the fixing hole, though riveted way has the benefit that reduces environmental pollution, connects firmly inadequately, and shock resistance is poor; The applicant is in the Chinese utility model patent (patent No.: CN200820120275.9) disclose a kind of electrothermal tube and flange welding connection structure; Mainly comprise flange and electrothermal tube; At flange sheath of electrothermal tube position increase with top; One end and the flange of sheath are welded to connect, and the other end of sheath and the mouth of pipe of electrothermal tube are welded to connect.But there is baroque deficiency in this patent, and the utility model is the further improvement to this patent.
The utility model content
The utility model mainly is to solve above-mentioned technical problem, thereby provides a kind of simple in structure, reasonable in design, electrothermal tube fixation, fixing point precision high, the electrothermal tube that sealing and mechanical strength are good and the syndeton of flange.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
The syndeton of a kind of electrothermal tube and flange comprises flange and electrothermal tube, has the fixedly fixing hole of electrothermal tube on the flange, and an end of electrothermal tube inserts in the fixing hole, and described fixing hole is the flange hole, and the aperture, the outside and the electrothermal tube tube wall in flange hole are welded to connect;
As preferably, between the inwall in the tube wall of described electrothermal tube and flange hole through being welded to connect;
As preferably, being welded to connect to spot welding of the aperture, the outside in described flange hole and electrothermal tube tube wall is connected;
As preferably, dig to the inboard or the outside of flange in described flange hole;
As preferably, the mouth of pipe of described electrothermal tube flushes with the inboard aperture in flange hole, and an end of electrothermal tube eduction rod extends to outside the mouth of pipe of electrothermal tube;
As preferably, be provided with fixing plug between the mouth of pipe of described electrothermal tube and the electrothermal tube eduction rod;
As preferably, described flange is the recessed disc-shaped structure in bottom.
The fixing hole that the utility model flange and electrothermal tube cooperate is made the flange hole; Prolonged the contact length of flange and electrothermal tube; Soldering paste can fill up the gap between electrothermal tube and the flange in welding process, and the length of welding section is effectively prolonged, and has guaranteed sealing and the mechanical strength after the welding; Flange and the argon arc welding spot welding of electrothermal tube elder generation are fixed, and prevent the occurrence positions skew when crossing the high temperature soldering furnace of electrothermal tube and flange, guarantee the consistency and the accuracy of welding position.Therefore, the utlity model has simple in structure, reasonable in design, electrothermal tube fixation, fixing point precision advantages of higher.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is A place enlarged drawings in the accompanying drawing 1.
Among the figure: flange 1, electrothermal tube 2, flange hole 3, aperture, the outside 4, electrothermal tube eduction rod 5, chock plug 6, gap location 7.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment: like Fig. 1, shown in 2, the syndeton of a kind of electrothermal tube 2 of the utility model and flange 1 comprises flange 1 and electrothermal tube 2; Flange 1 is the recessed disc-shaped structure in bottom; The bottom is the plane, and flange 1 bottom has the fixing hole of electrothermal tube 2, and fixing hole is split into flange hole 3; Dig to the inboard of flange 1 in flange hole 3; One end of electrothermal tube 2 is in 4 insertion flange holes 3, aperture, 3 outside, flange hole, and the mouth of pipe of electrothermal tube 2 flushes with the inboard aperture in flange hole 3, and an end of electrothermal tube eduction rod 5 extends to outside the mouth of pipe of electrothermal tube; Be provided with the fixedly chock plug 6 of usefulness between the mouth of pipe of electrothermal tube and the electrothermal tube eduction rod, the aperture, the outside 4 in flange hole 3 is connected with argon arc welding spot welding with the tube wall of electrothermal tube 2.
The utility model adds opens flange hole 3 according to the number of the fixedly electrothermal tube of wanting 2 earlier man-hour on flange 1, penetrate in the flange hole 3 at the end with electrothermal tube 2, makes the mouth of pipe of electrothermal tube 2 concordant with 3 mouthfuls in flange 1 flange hole; Again electrothermal tube 2 mouths of pipe and flange 1 flange hole, 3 usefulness argon arc welding spot welding are fixed; Fit clearance place 7 between flange 1 flange hole 3 and electrothermal tube 2 is coated with Ni-based soldering paste (a kind of main component is the paste welding material of nickel) then; It is fixing that electrothermal tube that coats soldering paste 2 and flange 1 are promptly accomplished welding through the high-temperature soldering stove, realizes between the inwall in tube wall and flange hole of electrothermal tube through being welded to connect (not drawing among the figure).
