According to another aspect of the present invention, a kind of method of valve body structure welding is provided, method uses above-described embodiment
In valve body machining device welded, method includes the following steps:The valve body of welding is fixed in receiving portion, by valve body
Spool open;Be passed through nitrogen into the pipeline to be welded of valve body by the first protective device, by the second protective device to
It is passed through cooling water in receiving portion so that the main part of valve body is soaked in cooling water, at this point, the pipeline to valve body welds
Operation.During carrying out weld job to the pipeline of valve body, the second protective device constantly Cooling Water into receiving portion.
Specifically, conventional bonding technique flow:Dry wipe is impregnated in the hot water, then is wrapped in electronic expansion valve body table
Face, for damp strips using needing to change afterwards for several times, the moisture of wet cloth is caused welding quality hidden danger by flame calcination rapid evaporation.
There are the following problems for the above welding operation mode:
1, packet wet cloth efficiency is low, and each electric expansion valve takes 20s.
2, packet wet cloth flow:Dry wipe is impregnated in the hot water, twists off that wet cloth is wrapped in electronics again after partial moisture is swollen
On swollen valve body.
3, welding process Flame calcination wet cloth leads to wet cloth moisture evaporation, unstable to the cooling protection effect of spool.
4, long-time operation causes employee's both hands red and swollen, whitens, and staff labor intensity is larger to be difficult to competent post, production effect
Rate is low.
The application is improved based on above-mentioned defect, develops a kind of electric expansion valve water-soaking device, new production
Technique optimizes multiple working procedure with respect to the process that traditional handicraft eliminates packet wet cloth, and manpower and materials are greatly saved, and improves life
Efficiency is produced, while avoiding the problem of artificial packet wet cloth is difficult to ensure consistency well.
Original is changed to electric expansion valve being put into distilled water using electric expansion valve packet wet cloth welding manner and is welded, is reduced
Packet wet cloth acts.Electric expansion valve pipeline assembly welding manner is adjusted, design immersion welder, by electric expansion valve valve
Body immerses in limited post, carries out shower of supplying water in real time using air pump alignment limited post, cools down in time to valve body, protect in real time
Shield spool is not ruined.Opposite traditional approach soldering angle consistency is higher, improves electric expansion valve components welding uniform quality
Property.Welding electric expansion valve tube assembly can be made more simple and easy to do using the valve body machining device.
Such electric expansion valve is not suitable with using the pattern of traditional water box in the prior art, is set for electronic expansion valve structure
Count with certain angle limited post, on the one hand position it is more efficient, on the other hand can ensure welding operation.By valve when welding
Body immerses in limited post, is supplied water in real time using air pump and carries out circulating cooling to valve body, compares packet wet cloth cooling effect more preferably.It will be electric
Sub- expansion valve is put into distilled water and welds, and cancels packet wet cloth post, and scene carries out anatomy verification to welding rear valve body, and effect is good
Good, can effectively protect to valve body and spool improve production efficiency.Use the valve body machining device that can take water spray type, leaching
Ability of swimming, water jet or other way of supplying water carry out welding processing to valve body.
Electronic expansion valve body is entirely dipped into water, the inlet/outlet pipe of electric expansion valve, which is connected thereto pipe, to be welded,
Nitrogen filled protection must be carried out when welding.Pass through from spool it has to be noticed that the nitrogen being filled in order to prevent is heated to form high-temperature gas
Electric expansion valve is damaged, it must inflated with nitrogen be protected respectively from the inlet and outlet of expansion valve when welding.Tool operation is as follows:
As shown in figure 3, when welding left end is taken over, it is filled with nitrogen in left end, prevents from that component is caused to aoxidize when welding, simultaneously
Also ensure that the high temperature nitrogen of heating does not pass through from spool.When same welding right end is taken over, it is filled with nitrogen guarantee in right end and is added
The high temperature nitrogen of heat does not pass through from spool.It, can be with fountain head to electronic expansion valve body when welding electric expansion valve pipe group
It is continuously sprayed water, the size of water flow must ensure the whole surface for flowing through expanding valve body.As noted earlier,
Also nitrogen filled protection must be carried out when welding.It is passed through from spool it has to be noticed that the nitrogen being filled in order to prevent is heated to form high-temperature gas
Cross damage electric expansion valve, it must inflated with nitrogen be protected respectively from the inlet and outlet of expansion valve when welding.Concrete operations are as follows:
As shown in figure 4, when welding left end is taken over, it is filled with nitrogen in left end, prevents from that component is caused to aoxidize when welding, simultaneously
Also ensure that the high temperature nitrogen of heating does not pass through from spool.When same welding right end is taken over, it is filled with nitrogen guarantee in right end and is added
The high temperature nitrogen of heat does not pass through from spool.Wherein, f is weld in Fig. 2 to Fig. 4, and c can be a kind of spray equipment.
To sum up the operation is suitable for actual production site welding, repair can use a mineral water bottle when welding is sprayed water
Son, tank full water extrude the water in bottle when making a hole welding on lid, and continuous uniform is sprayed on valve body, in order to make
Water is sprayed onto on valve more uniformly, and first valve body can be wrapped up with immersion sleeve, when welding directly valve body dipping bath in water,
Water flow must be suitable, it is necessary to assure wet cloth is continuously in the state of moistening, absolutely notices that water cannot be sprayed onto valve inner.Welding
When expansion valve be open.Preferably solves the problems, such as electric expansion valve actual production welding process spool high temperature deformation.
Than that described above, it is also necessary to which explanation is " one embodiment " spoken of in the present specification, " another implementation
Example ", " embodiment " etc. refer to that specific features, structure or the feature of embodiment description is combined to be included in the application summary
Property description at least one embodiment in.It is not centainly to refer to the same reality that statement of the same race, which occur, in multiple places in the description
Apply example.Furthermore, it is understood that when describing a specific features, structure or feature in conjunction with any embodiment, what is advocated is knot
Other embodiment is closed to realize that this feature, structure or feature are also fallen within the scope of the present invention.
In the above-described embodiments, it all emphasizes particularly on different fields to the description of each embodiment, there is no the portion being described in detail in some embodiment
Point, it may refer to the associated description of other embodiment.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by repair
