Description
Technical field
A kind of concentric aligning tool of flange is the utility model is related to, specifically a kind of pressure piping flange is concentric
Aligning tool.
Background technology
SW with outside ring or metal serrated gasket are used between steam-water pipe flange, and using " son between high pressure flange
The connected mode of mother " mouth, once leakage, which occurs, to be needed to be repaired in time.For the maintenance of long campaigns pressure pipeline or heavy caliber
For the personnel of replacing valve, flange and valve are also or between flange, after the fastening bolt of connection is unclamped, all exist not
A mouthful problem is carved with degree：That is the Concentricity tolerance of flange faying face.Particularly equipment is arranged on some trenches or pipe arrangement
In the maintenance place of Relatively centralized, due to the limitation of space for maintenance, the adjustment of flange concentricity is extremely difficult.Maintenance, which need to remove, to be connect
Mouth flange exposes on the inside of sleeve pipe, carries out internal cleaning or part replacement, then flange is aligned back to dress with one heart.Prior art
Four sets of 5T jacks of maintenance, two 50T jack and some other auxiliary Heavy-duty Tools are, it is necessary to which 5 to 6 is time-consuming 4 small for each person
Shi Caineng is completed.These conventional use of service kits with it is common prize, not, the mode on top etc. use, even if flange connects reluctantly
Work(is connected into, also basic do not eliminate carves the influence that mouth is brought, or even can produce the safety problem of pipe leakage and equipment.Due to this
A little pipelines are run under high temperature, high pressure conditions for a long time, pipeline internal stress Relatively centralized, are more or less existed when plus installation
The defects of and multiple maintenance, whenever changing valve or during flange faying face sealing gasket, it is extremely prominent that pipeline carves lip reflex.
The content of the invention
In order to solve the problems of the prior art, there is provided one kind can simplify the dismounting work of major diameter pressure piping, ensure
Flange returns dress concentricity, ensures back the instrument of packing quality, and concrete technical scheme is：
A kind of major diameter high-pressure pipeline flange dismounts adjustment instrument, including C-shaped aperture card made of a steel bar, the C-shaped
The lower support bar diameter of hole card is adapted to flange hole, and the C-shaped aperture card upper support bar is provided with locking member.
The upper support bar opens bolt hole, and the locking member is the bolt through bolt hole.
It is rotatable screw rod that the upper support bar, which can be, and the locking member is nut and affixed integral pulled with its
Mouth hooks.
The utility model is applied to the large-diameter pipeline flange combining port maintenance of the large special equipment such as power station, boiler room
And large size valve more changes jobs.It is simple in construction, ensure the concentricity returned when filling of flange.This tool operation mode is simple just
Victory, lip reflex is carved for eliminating large-sized flange, can not be limited by field tool using space, fast and effectively complete equipment
Service work.
Brief description of the drawings
Fig. 1 is the structure chart of the example of the utility model one；
Fig. 2 is the use state figure of example one.
Fig. 3 is the structure chart of the example of the utility model two；
Fig. 4 is line A-A sectional view in Fig. 3；
Fig. 5 is the use state figure of example two.
Embodiment
Influence of the mouth to equipment is carved to eliminate flange, is prized, not, solve in the way of top etc. with common by former, is basic
The installation effect of equipment is not reached.Sometimes due to the reason of repairing, in order to ensure production work, even if flange is connected reluctantly
Mouth is carved to flange together, is not inherently eliminated, also or flange concentricity is somewhat excessive, it is most likely that again results in leakage.
So pressure-bearing class pipeline valve more change jobs it is very high to concentricity requirement.The maintenance angle of my unit maintainer from reality
Set out and combine the research and design of person skilled, by long-term practice, formulated a kind of simple and efficient high-strength behaviour
Make instrument.
The utility model is illustrated below in conjunction with the accompanying drawings, as shown in Figure 1-2, a kind of major diameter high-pressure pipeline flange is torn open
The whole instrument of adjustment, including C-shaped aperture card made of a steel bar, the diameter of lower support bar 3 of the C-shaped aperture card are adapted to flange hole；
The upper support bar 1 is provided with locking member.The upper support bar 1 opens bolt hole, and the locking member is through bolt hole
Bolt 2.
Lower support bar 3 of the present utility model supports also cross the flange hole of two flanges 4 when flange 4 separates under time delay
Bar 3 moves.
This dismounting adjustment instrument be applied to preferably to use simultaneously when dismounting major diameter high-pressure pipeline flange three or
Person four.
Application method of the present utility model is：
1st, each two sets of 12 inch, 18 inch adjustable wrenches are got out, dismounting adjustment instrument three described in the utility model, confirm flange
Connection concentricity adjustment work can start；
2nd, a fixing bolt in 12 directions of flange is removed, change the outfit this dismounting adjustment instrument one；
3rd, the bolt on 4 directions of flange is removed, change the outfit this dismounting adjustment instrument one；
4th, the bolt on 8 directions of flange is removed, change the outfit this dismounting adjustment instrument one；
5th, other all bolts are removed, separate two flanges；
6th, change internal part or carry out other processing；
7th, two flanges are re-closed, the bolt of vacant position is installed；
8th, above three dismounting adjustment instrument is removed respectively, returns dress bolt.
As in Figure 3-5, improvement of the present utility model, the upper support bar 1 are rotatable screw rod 6, the tight lock part
Part is nut 5 and hooks 7 with its affixed integral mouth of pulling.When screw rod 6 rotates, nut 5 can move forward and backward.
The above-mentioned outer end of screw rod 6 can add the convenient structure for rotating screw rod, and concrete mode is unlimited.
This structure can not only supported flange, can also make to pull mouth and hook by rotating screw rod and promote flange to move.Specifically make
Use method：It is after completing disassembling bolts, two flanges are slightly separated, pull enough mouth hook stretch and, rotate screw rod, make to pull mouth and hook and be moved out
It is dynamic, pull 3 points of mouth hook or multiple spot is puted forth effort to be displaced outwardly flange, return reverse during dress flange.
The advantages of the utility model：Pressure piping overhaul process simple in construction, greatly simplifying, it is often more important that guarantee connects
The concentricity returned when filling of mouth flange.The instrument designs simple and clear as shown in the figure, and independent operation is strong, utilizes flange bolt hole
Can be adjusted with a comprehensive mouthful concentricity of being carved to flange, can also in flange fastening bolt, at any time multi-angle to method
Blue concentricity is adjusted, and can complete the maintenance task of bearing pipe in a short time, is solved and is produced in puzzlement really
Present in problem.
