Shown embodiment has first couple of inner support bar 122-123 and second couple of outer support bar 120-121.As shown in the figure, described inner support bar 122 roughly is positioned at first end, 126 places of described pipeline 103A and 103B, and described inner support bar 123 roughly is positioned at second end, 127 places of described pipeline 103A and 103B.Also as shown in the figure, described outer support bar 120 roughly is positioned at described first end 126 places of described pipeline 103A and 103B, and described outer support bar 121 roughly is positioned at described second end 127 places of described pipeline 103A and 103B.In described embodiment, the every pair of described support bar 120,121 and 122,123 is located such that roughly preferably that all they are symmetrically located on described pipeline 103A and the 103B.Though the present invention is provided with the first pack support bar 122,123 and the second pack support bar 120,121, and any amount of support bar is set, for example single pack support bar 122,123 or 120,121, also within the scope of the invention.
As shown in Figure 1, support bar 120-123 is connected to described pipeline 103A and 103B by connecting joint or tie point 125.Described support bar 120-123 is welded to described pipeline 103A and 103B by gas tungsten arc welding (or gas tungsten arc welding (Gas Tungsten Arc Welding)) technology usually; but be to use other weldprocedure; for example flux cored arc welding (or flux-cored electrode arc-welding (Flux Cored Arc Welding)) technology, gas shield metal () polar arc weldering (Gas Metal Arc Welding), or with described support bar 120-123 brazing or soft soldering on described pipeline 103A and the 103B also all within the scope of the invention.
According to an aspect of the present invention, after described support bar 120-123 is connected to described pipeline 103A and 103B, use Local Heating Process or handle to be released in the stress that connects joint 125 places and described connection joint 125 is strengthened.According to present embodiment on the other hand, after described support bar 120-123 is connected to described pipeline 103A and 103B, can utilizes Local Heating Process or handle discharge pipeline 103A and being positioned at the stress near the described zone that is connected the joint 125 and being strengthened near the described zones that are connected the joint 125 of being positioned at of described pipeline 103A and 103B of 103B.
Use any thermal source all to fall within the scope of the invention in Local Heating Process or in handling.For example and without limitation, Fig. 2 shows the Local Heating Process of utilizing flame, described flame is for example from torch 200, and Fig. 3 shows Local Heating Process or the processing of using ruhmkorff coil 300, described ruhmkorff coil 300 be positioned described connection joint 125 around and/or described pipeline 103A and the contiguous described zone that is connected joint 125 of 103B.As shown in Figure 3, the basic element of character of heating system is AC power supplies 301 and ruhmkorff coil 300.It will be understood to those of skill in the art that described power supply 301 sends alternating current by described coil, produces magnetic field.When the contiguous described zone that is connected joint 125 of described connection joint 125 and/or described pipeline 103A and 103B is placed in the described ruhmkorff coil 300, as the situation among Fig. 3, the magnetic field eddy current of in the contiguous described zone that is connected joint 125 of described connection joint 125 and/or described pipeline 103A and 103B, inducting, described eddy current then do not needing the accurate amount of localized heat of generation under the situation about contact with described ruhmkorff coil 300 physics.
Regardless of thermal source, described Local Heating Process or only handle by heating described connection joint 125 and/or described pipeline 103A and with the contiguous described zone that is connected joint 125 of 103B it is enhanced and discharges its stress.In the present embodiment, described connection joint 125 and/or described pipeline 103A can be heated to the temperature of scope in 704 ℃ to 816 ℃ with the contiguous described zone that is connected joint 125 of 103B, and preferably, are heated at least 760 ℃.According to present embodiment on the other hand, in case carried out after the Local Heating Process, can allow described pipeline 103A, 103B and the air cooling of described support bar 120-123 assembly; Yet other method of cooling is as forced ventilation or quenching, also within the scope of the invention.
Therefore, method of the present invention allows to discharge stress under the situation of not using stove (or process furnace).And then, the preferred aspect of the method according to this invention, though not necessarily so, sensor module 10 can be installed under the situation of need not be for stress relief and cooling purpose and described pipeline 103A, 103B and described support bar 120-123 assembly being taken off from production line.And, the method according to this invention, all right.But be not certain, at other parts, for example described driving mechanism 104 or described transmitter 105-105 ' have been assembled into that described pipeline 103A, 103B are last afterwards to carry out local heat treatment again, so the stress relief process is not disturbed described assembling process.
The invention describes the concrete example how instruction those skilled in the art made and used optimal mode of the present invention.For the purpose of instruction inventive principle, simplify or omitted some traditional aspects.It will be appreciated by those skilled in the art that the various modification of these examples within the scope of the present invention.The limit that to the specific descriptions of the foregoing description is not all embodiment within the scope of the present invention that the contriver is thought is described.For example, though disclosed concrete example shows a pair of pipeline 103A, 103B among Fig. 1-3, the pipeline of employing any amount also within the scope of the invention.For example and without limitation, use one pipeline, for example pipeline 103A or 103B, and adopt at least one support bar to supporting structure also within the scope of the invention with described pipe connection.Described support bar can with described supporting structure be one or be connected on the described supporting structure in mode arbitrarily, described mode arbitrarily includes but not limited to, as welding, brazing or soft soldering.
Some element that those skilled in the art will recognize that the foregoing description can make up in a different manner or omit forming other embodiment, and these other embodiment also drops within scope of the present invention and the instruction.Those skilled in the art are also with clear, and the above embodiments can make up whole or in part to be formed on the additional embodiments within scope of the present invention and the instruction.
Therefore, though described specific embodiments of the invention and example at this for purpose of explanation, as recognized by those skilled in the art, the modification of various equivalences can also be arranged within the scope of the invention.May be used on other embodiment the embodiment above-described and illustrated in the accompanying drawings in this instruction that provides except those.Therefore, scope of the present invention is determined by following claim.
