Abstract
The utility model belongs to mechanical project technique area, which discloses a connection structure of the water inlet and outlet pipe and the wall body, especially to a connection structure of the water inlet and outlet pipe and the wall body of the copper cooling wall. The water inlet and outlet pipe with an expansion port is inserted into the expansion port part of the wall body connected with the water channel, and the outer edge of the expansion part of the water inlet and outlet pipe is welded with the wall body. The utility model increases the ability of the water inlet and outlet pipe to bear the vertical axial direction force of the water pipe, eliminates the welded stress and shortage existing in the angle part because of fillet weld, which is beneficial for the safe use of the connection of the water inlet and outlet pipe and the wall body, and can be widely uses in the connection structure of the water inlet and outlet pipe and the wall body of copper colling wall.
Description
Technical field
The utility model belongs to mechanical engineering technical field, discloses the syndeton of a kind of water inlet pipe and water outlet pipe and wall body, particularly the syndeton of copper cooling wall water inlet pipe and water outlet pipe and wall body.
Background technology
At present, the copper cooling wall that blast furnace uses mainly is to form water channel with whole copper coin through boring, and the water inlet pipe and water outlet pipe that is communicated with water channel by welding becomes product, as patent 00246026.2 described copper coin cooling stave.Technical characterstic of this class common that copper cooling wall has is: being connected between its water inlet pipe and water outlet pipe and the wall body, implement fillet welding after having adopted copper pipe directly to insert the boring that is communicated with water channel on the wall body.In recent years, the copper cooling wall that this fillet welding mode is produced has begun to go wrong, uses less than 5 years such as the original product from the import of PW company at certain blast furnace, promptly ruptures in a large number from the fillet welding position, brings significant damage for this blast furnace production and longevity.
Summary of the invention
The purpose of this utility model is: the syndeton of a kind of rising pipe and wall body is provided, and the syndeton of copper cooling wall water inlet pipe and water outlet pipe and wall body particularly is to eliminate the generation of above-mentioned situation.The utility model can be widely used on the syndeton of copper cooling wall water inlet pipe and water outlet pipe and wall body.
The technical scheme that realizes above-mentioned purpose is: existing water inlet pipe and water outlet pipe after enlarging, is inserted wall body enlarging place that is communicated with water channel, take jam welding between the enlarging outer rim of water inlet pipe and water outlet pipe and wall body.
Beneficial effect of the present invention is embodied in:
Compare with existing fillet welding mode, take the jam welding mode can significantly improve water inlet pipe and water outlet pipe the pulling force that forms perpendicular to the axial alternating displacement of water pipe that can bear, fundamentally eliminated simultaneously be present between water inlet pipe and water outlet pipe and wall body the bight, because formed welding stress of fillet welding and defective.In the copper cooling wall use, because the slag crust slippage in the stove, the variation that causes the wall body temperature to go round and begin again, copper cooling wall expands along its length repeatedly, displacement thereby make, be present in for this reason the bight, because the formed welding stress of fillet welding and other welding flaw, become to cause between water inlet pipe and water outlet pipe and wall body and major cause of failure occurs.Therefore, new texture disclosed in the utility model, strengthened water inlet pipe and water outlet pipe and born ability perpendicular to the water pipe axial force, eliminated be present in the bight, because the formed welding stress of fillet welding and defective, useful to the safe handling that is connected between water inlet pipe and water outlet pipe and wall body undoubtedly.
Description of drawings
Accompanying drawing is a structure sectional view of the present utility model;
In the accompanying drawing: part 1 is a water inlet pipe and water outlet pipe, and part 2 is a wall body, and part 3 is a water channel, and part 4 is enlarging.
Embodiment
Below in conjunction with accompanying drawing the present invention is specified:
As shown in Figure 1, water inlet pipe and water outlet pipe 1 has enlarging 4, and wall body 2 enlargings place that are communicated with water channel 3 are inserted in enlarging 4, and enlarging 4 outer rims and 2 of the wall bodies of water inlet pipe and water outlet pipe are taked jam welding.
New texture disclosed in the utility model has strengthened water inlet pipe and water outlet pipe and has born ability perpendicular to the water pipe axial force, eliminated be present in the bight, because the formed welding stress of fillet welding and defective, useful to the safe handling that is connected between water inlet pipe and water outlet pipe and wall body undoubtedly.The utility model can be widely used on the syndeton of copper cooling wall water inlet pipe and water outlet pipe and wall body.
Claims (1)
1. the syndeton of water inlet pipe and water outlet pipe and wall body, it is characterized in that: wall body (2) enlarging place that is communicated with water channel (3) is inserted in the enlarging (4) of water inlet pipe and water outlet pipe (1), takes jam welding between the enlarging of water inlet pipe and water outlet pipe (4) outer rim and wall body (2).
