Description
Technical field
The utility model is related to air-supply apparatus of blast furnace technical field, more particularly to a kind of air-tight test work of lower section assembling
Dress.
Background technology
Lower section assembling at this stage is the important component of air-supply apparatus of blast furnace, is also a weak link in supply air system,
Its structure is：Flange five, lower section halfbody I, bellows, attachment structure, lower section halfbody II and flange four refer to accompanying drawing 1.It makes
When critical process be to need to carry out air-tight test, pressure requirements 0.4MPa after integral solder terminates.
Conventional air pressure method is to seal twice section halfbody end flanges, is internally poured workpiece table after compressed air
Face weld seam position smears suds, and it is just breakthrough to blow afloat position lathery.Normal squeezing air duct pressure is about 0.7 ~
0.8MPa, therefore after lower section assembling with compressed air piping UNICOM, its internal pressure just reaches when being balanced with manifold pressure
More than 0.7MPa.Because without effectively monitoring the means of internal pressure, therefore now suppress and can be easy to be held beyond this equipment
Pressure energy power, will bring great potential safety hazard, and it is serious non-that hypertonia can cause the middle bellows for playing cushioning effect to produce
Elastic stretching deforms, so as to cause bellows to be scrapped.
Urgently need a kind of i.e. easy to loading and unloading at present, the frock of air pressure inside situation can be intuitively reflected again, it is above-mentioned to solve
There is problem.
Utility model content
In order to solve the above-mentioned technical problem the utility model provides a kind of airtightness testing tool of lower section assembling, is lower section
Assembly production and checkout procedure provide quality and safety assurance when doing air-tight test.
The utility model is realized by following technical measures：A kind of airtightness testing tool of lower section assembling, with
Section assembling structure is supported the use, and the frock is connected thereto part includes flange five and flange four, also including frock I and frock II,
The frock I is affixed with flange four, and the frock II is affixed with flange five；The lateral surface of the frock I is provided with air gauge and enters gas
Joint；The air inlet joint connects compressed air piping.After using this technology measure, there is provided a kind of i.e. easy to loading and unloading, again can be straight
The frock of reflection air pressure inside situation is seen, the sealing frock of two end flanges, and one pressure of ingenious installation on is specially devised
Power table, is allowed to be connected with inside cavity, so that internal directly read on pressure gauge, is carried while quality and safety is effectively ensured
High efficiency.
Preferably, the medial surface of the frock I and the patch merga pass seal sealing of the lateral surface of flange four；The frock II
Medial surface and the patch merga pass seal sealing of the lateral surface of flange five.Using after this preferred scheme, ensure that overall air-tightness.
Compared with prior art, the utility model beneficial effect can be learnt according to the narration to above-mentioned measure：Overcome existing
The mode of suppressing can be easy to the defect of the bearing capacity beyond equipment, there is provided a kind of compact conformation is rigidly good, can be according to done gas
The workpiece of the different structure of tightness test carries out bulge test；Can the flexible fast assembling-disassembling according to the characteristics of test structure, realize
It is portable intuitively to reflect air pressure inside situation, significantly improve the bellows caused by pressure testing is excessive and produce serious non-resilient drawing
Stretch deformation；For test result provides reliable and stable data, quality and safety is can effectively ensure that；It is relatively advanced in similar frock,
Its reuse can be the daily production maintenance cost of machine industry reduction and then the creation of value.

Specific embodiment
For the technical characterstic for illustrating this programme can be understood, below by specific embodiment, this programme is illustrated.
Referring to the drawings 1-6, a kind of embodiment of the airtightness testing tool of lower section assembling：A kind of air-tightness of lower section assembling
Test tool is supported the use with lower section assembling structure, according to the complete field of structure design of part flange 51 and flange 46 in lower section assembling
Combination sealing carries out suppressing work.With the Q235-B steel plates that thickness is 20mm respectively by under flange 51, the profile gas cutting of flange 46
Expect each one i.e. frock II 8 and frock I 7, and match somebody with somebody the brill connecting holes I of Φ 32 in frock I 7 by the bolt groove location in flange 46
7.2；Two circular holes of Φ 12 7.1 are bored into the centre position of frock I 7 simultaneously, as shown in accompanying drawing 2,3,6；Similarly flange 51 and frock
II 8 are fixed using same method by connecting hole II 8.1, as shown in accompanying drawing 4,5,6.When using, by two pieces frock I 7 and work
Fill II 8 to be connected by bolt 12 with flange 46 in lower section assembling and flange 51 respectively, respectively stopping in respective its spacer flanger
Rubber blanket 13 is padded for sealing in oral area position.The circular holes 7.1 of a Φ 12 in frock I 7 are welded into air inlet joint 10 for connecting
Compressed air piping, another 12 circular hole of Φ 7.1 welding air gauge 9, makes it be all connected with internal cavities.After connection source of the gas now
The gas pressure of internal cavities can be directly displayed on air gauge 9, and section assembling downwards is internal when suppressing is passed through gases at high pressure, waits to press
Power meter reading just closes air valve when slowly rising to drawing requirement pressure 0.4MPa.Now the air pressure of the device interior is in its work
In pressure limit, it is ensured that be not in any danger on the premise of quality.It is easy to quality inspection personnel inspection simultaneously, air gauge can a mesh
It is clear and sees whether internal pressure has reached Design Requirement Drawing.
Certainly, described above is also not limited to the example above, and technical characteristic of the utility model without description can lead to
Cross or such as external gas source and pneumatic equipment are realized using prior art, will not be repeated here；Above example and accompanying drawing are only used for
Illustrate that the technical solution of the utility model is not to limitation of the present utility model, with reference to preferred embodiment new to this practicality
Type has been described in detail, it will be understood by those within the art that, those skilled in the art are in this reality
With the change, remodeling, addition made in new essential scope or replace without departure from objective of the present utility model, should also belong to
In claims of the present utility model.
