Abstract
The present invention relates to a kind of blocking Leakage methods, its leak repairing step is: first making one for being welded in the seal pipe of pipeline leakage, one end of seal pipe prepares to be welded on the failure pipeline of leakage, so the outer surface of the pipeline of this one end and leakage of seal pipe will cooperate closely convenient for welding, the other end of seal pipe is connected with valve；Seal pipe the one end for not filling valve close to the pipeline of leakage by valve opening, and leakage point is in the inner cavity of sealing pipeline, and since valve is in the open state, the pressure in seal pipe is close to atmospheric pressure, convenient for welding；Abutment joint between seal pipe and leakage pipeline is welded, welding quality meets seal request；Close valve.Maintenance process, method simple practical can be carried out to pipeline leakage point in the case where pipeline is not stopped using.
Description
Technical field
The invention belongs to leakage mending technique fields, are related to a kind of blocking Leakage method.
Background technique
Pipeline is widely used in industrial production, and pipeline is in use because a variety of causes is it is possible that leakage.Usually
After pipeline leakage occurs, after stopping pipeline use, replacement or repairing pipeline.If stopping pipeline wearing using processing pipeline
Leakage can have an impact to production, some possible situations cause serious economic loss.There are more leakage pipeline needs using
Leak stopping is carried out in journey.
Summary of the invention
In order to overcome the disadvantages mentioned above of the prior art, the present invention provides a kind of blocking Leakage method, it can pipeline not
In the case where stopping using, maintenance process, method simple practical are carried out to pipeline leakage point.
The technical solution adopted by the present invention to solve the technical problems is: a kind of blocking Leakage method, leak repairing step is:
1. first making one for being welded in the seal pipe of pipeline leakage, one end of seal pipe prepares the failure pipe for being welded on leakage
On road, so the outer surface of the pipeline of this one end and leakage of seal pipe will cooperate close convenient for welding, the other end of seal pipe
It is connected with valve；
2. seal pipe, the pipeline for not filling one end of valve close to leakage by valve opening, leakage point is in the inner cavity of sealing pipeline
In, since valve is in the open state, the pressure in seal pipe is close to atmospheric pressure, convenient for welding；
3. the abutment joint between seal pipe and leakage pipeline is welded, welding quality meets seal request；
4. closing valve.
The first step is first completed before welding leak repairing.
The positive effect of the present invention is: in the state of not stopping conduit running, can carry out pipeline welding leak repairing, difficulty
It is smaller, there is very much practicability.
Detailed description of the invention
Fig. 1 is 1 structural schematic diagram of embodiment；
Fig. 2 is another embodiment schematic diagram.
In figure: 1- pipeline, 2- leakage point, the big seal pipe of 3-, 4- flange, 5- gasket, 6- screw bolt and nut, 7- steel plate,
The small seal pipe of 8-, 9- valve.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and embodiments.
Referring to Fig. 1 and Fig. 2, a kind of blocking Leakage method, leak repairing step is:
1. first making one for being welded in the seal pipe of pipeline leakage, one end of seal pipe prepares the failure pipe for being welded on leakage
On road, so the outer surface of the pipeline of this one end and leakage of seal pipe will cooperate close convenient for welding, the other end of seal pipe
It is connected with valve；
2. seal pipe, the pipeline for not filling one end of valve close to leakage by valve opening, leakage point is in the inner cavity of sealing pipeline
In, since valve is in the open state, the pressure in seal pipe is close to atmospheric pressure, convenient for welding；
3. the abutment joint between seal pipe and leakage pipeline is welded, welding quality meets seal request；
4. closing valve.
The first step is first completed before welding leak repairing.
Embodiment 1
A kind of blocking Leakage method, leak repairing step is:
1. the pipeline 1 of leakage is the sintering machine wind box of smelter and the connecting tube of large flue, air pressure is forced down than atmosphere in pipeline 1
16kpa, the medium in pipeline 1 are sintering flue gas, predominantly air, no kindling, explosion risk, the diameter of pipeline 1 is
1200mm, 2 diameter 20mm of leakage point, the corrosion of the pipe wall and serious wear of pipeline 1 in the range of 2 surrounding about 100mm of leakage point.
2. preparing the big seal pipe 3 of a diameter 300mm, big seal pipe 3 is 200mm long, and one end of big seal pipe 3 is according to wearing
The shape of 2 surrounding conduit 1 of leak source, which is repaired, cuts out end face, so that cooperation is close between the big end face of seal pipe 3 and the pipeline 1 of leakage,
Convenient for welding.
3. the other end of big seal pipe 3 welds a flange 4, one steel plate 7 matched with flange 4 of production, on steel plate 7
The hole that a diameter is 50mm is opened, the small seal pipe 8 that a diameter is 50mm is welded on hole, in the other end of small seal pipe 8
One valve 9 is installed by thread.
4. there is gasket 5 between steel plate 7 and flange 4, flange 4, gasket 5 and steel plate 7 are fastened on screw bolt and nut 6
Together.
5. opening valve 9, the end face worked good between big seal pipe 3 and the pipeline 1 of leakage is docked to the pipeline 1 of leakage
On, leakage point 2 is in the inner cavity of big sealing pipeline 3, welds the abutment joint between big seal pipe 3 and leakage pipeline 1.Due to valve
Door 9 is in the open state, and for the pressure in big seal pipe 3 close to atmospheric pressure, the pressure on 2 side of soldered is almost equal, and welding is difficult
It spends small.
6. closing valve 9.Leak repairing work is completed.
Sintering machine air draft pipe is carried out using this method not need sintering machine shutdown, difficulty of construction in wire bonding leak repairing
It is small, it does not leak out after welding leak repairing, can leak out to sintering is reduced, be conducive to improve blower energy utilization rate.
Claims (2)
1. a kind of blocking Leakage method, it is characterised in that leak repairing step is:
(1) one is first made for being welded in the seal pipe of pipeline leakage, and one end of seal pipe prepares the failure for being welded on leakage
On pipeline, thus the outer surface of the pipeline of this one end and leakage of seal pipe to cooperate it is close convenient for welding, seal pipe it is another
End is connected with valve；
(2) seal pipe, the pipeline for not filling one end of valve close to leakage by valve opening, and leakage point is in the inner cavity of sealing pipeline
In, since valve is in the open state, the pressure in seal pipe is close to atmospheric pressure, convenient for welding；
(3) abutment joint between seal pipe and leakage pipeline is welded, welding quality meets seal request；
(4) valve is closed.
