Detailed description of the invention
The embodiment of the present invention will be described in further detail below.
The present invention is exclusively used in the U-tube anti-vibrating of heat exchanger bend loss, and its preferably detailed description of the invention is:
Including sheet frame, rolling pipe collar, described rolling pipe collar includes that many round steel rollings form, and is formed between adjacent round steel
The shape coincideing with heat exchanger bend pipe outer wall the inner side being welded on described sheet frame, the tube bank of heat exchanger bend pipe interts into rolling pipe collar
In, described sheet frame is connected fixing with the deflection plate of heat exchanger bend pipe tube bank tail end.
Described sheet frame and rolling pipe collar are one group, and described sheet frame directly welds with the deflection plate of heat exchanger bend pipe tube bank tail end
Fixing, described deflection plate has gusset with the corner welding being connected outside sheet frame.
Described sheet frame and rolling pipe collar are many groups, many group sheet frames baffling by connecting plate with heat exchanger bend pipe tube bank tail end
Plate connects.
Described heat exchanger bend loss be cloth form of tubes be the U-tube bundle of 30 ° and 60 °.
The present invention is exclusively used in the U-tube anti-vibrating of heat exchanger bend loss, it is adaptable to heat exchanger tube cloth form of tubes is 30 ° and 60 °
The U-tube bundle of stringing, it is to avoid traditional lath cutting forming tubulation hoop, occurs that cutting accuracy is difficult to ensure card, the problem assembling difficulty,
The pipe collar laminating heat exchanger tube outer wall of rollforming, can effectively alleviate the vibration of U-shaped heat exchange tube Beam End end.
Specific embodiment:
As shown in Figure 1 to Figure 3, including sheet frame 1, rolling pipe collar 2, gusset 3, connecting plate 4；Described rolling pipe collar 2 is 2 circles
Steel rolling given shape interts after tube bank, is welded to connect with sheet frame 1, constitutes special type pipe collar frame, described sheet frame 1 and tube bank tail
End deflection plate is welded and fixed, and described gusset 3 is welded to connect deflection plate and sheet frame 1；One group can be increased very when restraining size and being bigger
At most group pipe collar frame, is welded on deflection plate through described connecting plate 4, is i.e. exclusively used in the U-tube anti-vibrating of heat exchanger bend loss and installs
Complete.
Fig. 1 is the structural representation only arranging one group of special type pipe collar frame, and in figure, each row's heat exchanger tube inserts a pair rolling pipe
Hoop 2, is welded in sheet frame 1, and sheet frame 1 is welded to connect with tail end deflection plate；
Fig. 2 is the anti-vibrating schematic diagram arranging two groups of special type pipe collar frames, and in figure, two groups of special type pipe collar frames pass through gusset 3, connect
In fishplate bar 4 welding and deflection plate；
Fig. 3 is the A-A view of Fig. 1 and Fig. 2, and in figure, in the tube bank of 30 ° of cloth form of tubes, often row's heat exchanger tube inserts a pair point
The rolling pipe collar 2 that weldering is in parallel, through being rolled into the waveform of laminating heat exchanger tube arrangement profile, is welded in sheet frame 1, reinforces through gusset 3
It is welded on deflection plate.
The embodiment of the present invention be exclusively used in the U-tube anti-vibrating of heat exchanger bend loss, described rolling pipe collar 2 is according to cloth form of tubes
Rollforming, heat exchanger tube outer wall of fitting, it is particularly well-suited to the U-tube bundle that heat exchanger tube cloth form of tubes is 30 ° and 60 ° stringings, pipe collar 2
Use round steel, can effectively alleviate the vibration of U-shaped heat exchange tube Beam End end.
As it is shown on figure 3, in the tube bank of described 30 ° of cloth form of tubes, often row's heat exchanger tube inserts rolling pipe collar 2, described rolling pipe
Hoop 2 is the round steel in parallel by a pair spot welding, makes the waveform of the laminating exclusive shape of heat exchanger tube through prior rolling, penetrates in tube bank
After, two ends are welded in sheet frame 1, and described sheet frame 1 is the long lath with one fixed width, is wound on tube bank most external, reinforces through gusset 3
After, it is welded on deflection plate, is so far exclusively used in the anti-vibrating fabrication and installation of U-tube heat exchanger bend loss and completes.
When restraining size and being bigger, one group of pipe collar frame antihunt action is not enough, can increase by one group of even multi units tube hoop frame, manufactures
Connecting plate 4 is welded to connect to deflection plate or support plate (as shown in Figure 2) after gusset 3 is reinforced again.
In sum, what the embodiment of the present invention provided is exclusively used in the U-tube anti-vibrating of heat exchanger bend loss, described rolling pipe collar
2 can carry out roll forming according to different comb forms, use round steel to have the bonding strength more higher than steel plate strip and rigidity；
When equipment tube bank size increases can the quantity of flexible design pipe collar frame and type of attachment, improve vibration-isolating effect.
