Significantly.Condensing-type unit, high back pressure heat supply heat heat supply network recirculated water by improving low pressure (LP) cylinder exhaust steam pressure and exhaust temperature
Reach heat supply purpose.
With the upgrading that national energy conservation and emission reduction requires, the ideal high back pressure condenser heat supply of energy-saving effect is promoted rapidly
It comes, so-called high back pressure condenser heat supply is exactly that municipal heat supply hot net water introducing condenser is made full use of the weary of turbine discharge
Heat heating hot net water.High back pressure condenser when being welded at the scene with expansion joint usual welding angle height reach 20mm, in welding process
In easily base material is caused to deform, cause the use quality of high back pressure condenser to reduce, reduced service life.
Utility model content
Utility model aims to solve easily base material being caused to deform in the welding process, provide a kind of high
The auxiliary welding tool of back pressure condenser expansion joint.
The technical solution adopted in the utility model is as follows：
A kind of auxiliary welding tool of high back pressure condenser expansion joint, including sheath, the sheath are set as semi-ring bucket
Shape, the sheath lower section are provided with cooling zone, and the cooling zone is provided with High-temperature cooling device, and the sheath side is provided with solid
Determine hole, the mounting hole is arranged on the bulge of half ring bucket, and it is quadrant at bulge to be set as distance
Distance, the mounting hole are provided with dismountable connecting rod, and the connecting rod connects corresponding mounting hole.
Further, the sheath is that half ring bucket or semi-ring are horn-like, the annular surface that the semi-ring, that is, angle is 180 °.
Further, the connecting rod is bolted on mounting hole, and the connecting rod can be also hinged and mounting hole.
Further, the sheath uses alloy material, the size of the semi-ring of the sheath bigger than the weld of expansion joint
3cm~6cm.
Further, the auxiliary welding tool is formed using 4 sheaths, and in use, is carried out using dislocation fixation
Fixed, two sheaths are spliced into a circle, and corresponding two sheaths are also spliced into a circle, and one of circle is rotated by 90 °,
It is attached the connection of bar, dislocation is formed and fixes.
In conclusion by adopting the above-described technical solution, the utility model has the beneficial effects that：
1. the auxiliary welding tool of the utility model design can be protected base material when carrying out the welding of expansion joint
Shield so that base material is unlikely to deform, and influences the use of expansion joint；
2. the cooling zone that the utility model uses can will cool down the spark etc. to splash in welding process so that weldering
The temperature at the place of connecing does not diffuse into base material, further protects base material；
3. the utility model uses tubbiness or horn-like, the spark of splashes is completely cut off except base material so that entire
Welding process can directly concentrate on the process problem welded without worrying spark；
4. the utility model uses dislocation fixation, and 4 sheath groups are integral, need to can only be fixed by connecting rod,
Reduce fixed step；
5. the sheath of the utility model is dimensioned to bigger 3cm~6cm than weld, fine rotation can be carried out, it will not
Connecting rod is allowed to influence welding process.
Description of the drawings
The utility model will illustrate by example and with reference to the appended drawing, wherein：
