Detailed description of the invention
Illustrate the utility model embodiment or technical solution in the prior art in order to clearer, it below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it is clear that, to those skilled in the art,
Without creative efforts, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is a kind of structural schematic diagram of pressure pipeline leak source soldering device with pressure provided by the embodiment of the utility model.
Fig. 2 is the structural representation of another pressure pipeline leak source provided by the embodiment of the utility model soldering device with pressure
Figure.
It is as shown in the figure: bolt 1, nut 2, pressure pipeline 3, shield 4.
Specific embodiment
It, below will be practical to this in order to make those skilled in the art more fully understand the technical solution in the utility model
Technical solution in new embodiment is clearly and completely described, it is clear that described embodiment is only the utility model
A part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, those skilled in the art are not having
Every other embodiment obtained under the premise of creative work is made, the protection scope of the utility model all should belong to.
Referring to Fig. 1, it show a kind of knot of pressure pipeline leak source soldering device with pressure provided by the embodiment of the utility model
Structure schematic diagram.
As shown in Figure 1, the pressure pipeline leak source soldering device with pressure includes on the outside of the leak source for being fixed on pressure pipeline 3
Nut 2, the screw hole of the nut 2 is connected with the leak source of the pressure pipeline 3, and the center line and pressure of the screw hole of nut 2
The center line of leak source on hydraulic piping 3 is overlapped, and the screw hole internal diameter of the nut 2 is greater than the leak source outer diameter on pressure pipeline 3, i.e.,
The leak source of pressure pipeline 3 is placed exactly in the screw hole of nut 2, and the bolt matched with the nut 2 is fixed in the nut 2
1。
In the present embodiment, the nut 2 is fixedly welded on the pressure pipeline 3, the bolt 1 and the nut 2
Screw thread is taper pipe thread；Weld seam between the nut 2 and the pressure pipeline 3 is welded sealing；The nut of the bolt 1 and institute
The gap between nut 2 is stated by being welded sealing.
Pressure pipeline leak source soldering device with pressure provided in this embodiment is in use, be weldingly fixed on pressure for nut 2 first
It on hydraulic piping 3, is fully located at the leak source on pressure pipeline 3 in the screw hole of nut 2, and ensures that nut and leakage pipe weld seam weld
Quality and leakproofness are connect, certainly, the size of nut 2 is selected according to the size of leak source, screwing hermetic then is carried out with bolt 1,
This sealing means for blocking leak source, directly weld one in leak source relative to one piece of patch is welded directly at electric leakage
When block patch, a Zhou Douhui of welding has the impact such as pressed gas, still can leak, and the present embodiment, leak source are located at spiral shell
In mother 2, pressed gas etc. of leak source leakage along nut 2 screw hole forward, without the welding to nut 2 and pressure pipeline 3
Place is impacted, and bolt 1 is screwed in the screw hole of nut 2, the taper pipe thread on bolt 1 and nut 2 is to the pressure gas in screw hole
Body etc. carries out bending barrier, and the leakage of pressed gas etc. can be stopped after screwing bolt, because bolt 2 and nut 2 are cone
Pipe screw thread, the pressed gas etc. gone out along the screw hole of nut 2 are difficult to continue to leak out under the continuous extruding of taper pipe thread,
And bolt 1 screw after the weld seam between nut 2 and pressure pipeline 3 is welded sealing, the seam between the nut and nut of bolt 1
Gap increases leakproofness, prevents pipe leakage, it is ensured that solve the problems, such as, keep away in non-stop-machine situation also by sealing is welded
Exempt from the impact in welding process directly facing high pressure water, is in welding process in normal atmosphere (An) force environment, to improve
It is welded into power.
It must be operated by the welding personnel for having pipeline Weldability during the welding of the present embodiment, only in this way
It is just able to achieve simple and resolves safely problem.
Further, as shown in Fig. 2, for another pressure pipeline leak source soldering dress with pressure provided by the embodiment of the utility model
The structural schematic diagram set.
As shown in Fig. 2, the present embodiment is on the basis of the above embodiments, it is described in the outside fixed blade guard 4 of nut 2
Shield 4 and the pressure pipeline 3 sealing are fixed, and the nut 2 and the bolt 1 are located in the shield 4, and the spiral shell
Resilient material is filled in the shield 4 in 1 outside of mother 2 and the bolt.In the present embodiment, the setting of shield can be further
The leak source of pressure pipeline is sealed, prevents there are pressure leakages in weld seam, once due to the sealing between nut 2 and bolt 1
Property it is bad and make pressure leakages, the elastic material filled in shield 4 can buffer the pressure of leakage.
Certainly, above description is also not limited to the example above, and technical characteristic of the utility model without description can lead to
It crosses or realizes that details are not described herein using the prior art；Above embodiments are merely to illustrate the technical solution of the utility model simultaneously
