Description
Technical field
The utility model relates to leak proof technology fields, and in particular to a kind of hydrogen-cooled device heat exchanger tube pipeline plugging pig of generator.
Background technique
More frequent to the cleaning of generator hydrogen-cooled device for Steam Turbine power conservation requirement, the heat exchanger tube after cleaning is sometimes
There is damaged leakage situation, leak stopping defect elimination is reliably carried out very much after pressure testing inspection, but the heat exchanger tube of heat exchanger as everybody knows
Side is that need cooling working medium hydrogen, the other side be cooling medium, in order to make media of both sides not because heat exchanger tube breakage is ganged up, is needed
Damaged heat exchanger tube is reliably blocked, the method used before this is indignant two kinds big: first is that changing in cooler breakage
The taper plug of heat pipe both ends production beats the tight method of contract and blocks, and the method is less reliable, there is the phenomenon that falling off sometimes；Two
It is to be blocked in such a way that installed plug is sealed welding again, the method is reliable but is influenced by factors such as environment, media,
(for example Medium Oil, hydrogen cannot get angry welding, and narrow space is unable to welding etc.), both of which has disadvantage！There are one than
Larger problem, two methods, which will open wide the both ends tube sheet of cooler, just can be carried out leak stopping, for example the hydrogen-cooled device of generator is stifled
Leakage needs to release cooler above generator, and workload is very big, takes a long time.
Based on background above, in order to improve leak stopping reliability and reduce workload, shortening maintenance duration, it is necessary to existing
The leak stopping structure of the hydrogen-cooled device heat exchanger tube of the generator of technology improves.
Utility model content
In view of this, the purpose of the utility model is to provide a kind of hydrogen-cooled device heat exchanger tube pipeline plugging pig of generator, so as to broken
The hydrogen-cooled device heat exchanger tube of damage, which is realized, accurately, conveniently, safely, fast reliably to be blocked.
The utility model is solved the above problems by following technological means: a kind of hydrogen-cooled device heat exchanger tube pipeline plugging pig of generator,
Including blind hole sphenocephaly, stretching screw, through-hole sphenocephaly, gasket, fastening nut, sealing shroud and bushing, the stretching screw
The blind threaded connection opened up in one end and blind hole sphenocephaly, the other end sequentially pass through after through-hole sphenocephaly and gasket with fastening
Nut thread connection, is arranged with sealing shroud outside blind hole sphenocephaly and through-hole sphenocephaly, and the bushing is in two sealings
Between set.
Further, the bushing is made of stainless steel.
Further, the sealing shroud is made of soft metal, elastoplastic or rubber material.
Further, the blind hole sphenocephaly, through-hole sphenocephaly, fastening screw and fastening nut are by carbon steel or stainless steel
Material is made.
Further, the step with bushing support connection is provided on the sealing shroud.
The utility model has the beneficial effects that the hydrogen-cooled device heat exchanger tube pipeline plugging pig of the generator of the structure, including blind hole sphenocephaly,
Stretching screw, through-hole sphenocephaly, gasket, fastening nut, sealing shroud and bushing, described stretching screw one end and blind hole sphenocephaly
The blind threaded connection inside opened up, the other end are threadedly coupled after sequentially passing through through-hole sphenocephaly and gasket with fastening nut,
Sealing shroud is arranged with outside blind hole sphenocephaly and through-hole sphenocephaly, the bushing is between two sealing shrouds.The structure
Hydrogen-cooled device heat exchanger tube pipeline plugging pig can realize damaged hydrogen-cooled device heat exchanger tube and accurately, conveniently, safely, fast reliably block, have
Effect improves the reliability of leak stopping, while reducing workload, shortening maintenance duration.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in detail below with reference to attached drawing, as shown in Figure 1: the generator hydrogen of the utility model
Cooler heat exchanger tube pipeline plugging pig, including blind hole sphenocephaly 1, stretching screw 7, through-hole sphenocephaly 4, gasket 5, fastening nut 6, sealing
The blind threaded connection opened up in set 2 and bushing 3, described stretching screw one end and blind hole sphenocephaly, the other end sequentially passes through logical
It is threadedly coupled after hole sphenocephaly and gasket with fastening nut, is arranged with sealing outside blind hole sphenocephaly and through-hole sphenocephaly
Set, the bushing are between two sealing shrouds.The bushing is made of stainless steel, according to the whole of required pipeline plugging pig
Body length intercepts the bushing of different length, to satisfy the use demand.The sealing shroud is by soft metal, elastoplastic or rubber
Material is made, the internal diameter of the pipeline selection of the outer diameter of sealing shroud leak stopping as needed.It is the blind hole sphenocephaly, through-hole sphenocephaly, tight
Gu screw rod and fastening nut are made of carbon steel or stainless steel material.The platform with bushing support connection is provided on the sealing shroud
Rank.
Working principle:
In use, the pipeline plugging pig insertion after assembling needs to screw fastening nut with spanner in the pipeline of leak stopping, pull
Blind hole sphenocephaly and through-hole sphenocephaly squeeze corresponding sealing shroud, and sealing shroud is made to expand and carry out leak stopping to pipeline.Installation
When, assembling external member is not serious solid in outside, and otherwise sealing shroud, which is swollen, causes not being inserted into, as long as not loosening, installation is extremely
It just can be carried out fastening in pipeline.
Using the pipeline plugging pig of the application, damaged hydrogen-cooled device heat exchanger tube can be realized accurately, conveniently, safely, it is fast reliable
Closure, effectively increase the reliability of leak stopping, while reducing workload, shortening maintenance duration.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover in the scope of the claims of the utility model.
