Description
Technical field
The present invention relates to piping failure restorative procedure technical fields, and in particular to it is a kind of can rapidly and efficiently pipe-repairing it is interior
Jacketed tubular type pipeline craft leakage mending method.
Background technique
General pipeline gas leakage repairing is needed to air leak position after pipeline stops vapour, and external from pipeline carries out repair welding.
Currently, generalling use from the outside of pipeline and being repaired to its damaged position when damaged leakage occurs for various pipes
It mends.But most of pipeline is suitable for gas or liquid that conveying has certain pressure, in pipeline air pressure inside or hydraulic pressure
Under power effect, the damaged part after being repaired can reappear breakage, or even can generate the breakage more introduced a fine variety.In addition from pipeline
Damaged position is repaired in outside, needs to realize and is cleaned, polished to the outer wall of pipeline.Certainly will return in this way makes its surface
Certain damage is caused, and there are many very intensive of conduit arrangements, is not easy to clean it, or even be not easy to it
It is repaired.Pipe leakage breakage can certainly be solved the problems, such as using the method for replacement pipeline, but some fields are made
The equipment of industry, or navigation naval vessel can not find sometimes can be used for replace pipe fitting, and be not easy to again it is right from the outside of pipeline
It is repaired.Therefore.It is necessary to design one kind can efficiently quickly repair leakage damaged part from the inner wall of pipeline
Multiple method.
Summary of the invention
It is an object of the present invention to overcome defect existing in the prior art, provide a kind of structure it is simple, it is easy to use,
Repairing effect is good, can efficiently quickly from the inner wall of pipeline leakage damaged part is repaired in jacketed tubular type pipeline mend
Leakage method.
To achieve the above object, the technical scheme is to design tubular type pipeline craft leakage mending methods jacketed in one kind, use
Leak site is repaired from pipeline inner wall, the method for repairing and mending includes the following steps:
S1, the material inside the pipeline with leakage defect is drained completely；
S2, the inner wall for draining clean pipeline is cleaned, drying and processing；
S3, one section of flexible casing is taken, opening up a gap in the side of casing makes the C-shaped openning shape in its section；
S4, in the inner wall coating hot-melt adhesive for being equipped with c-shaped opening shape casing, then magnetic send tube head be bonded with having it
Together, with the outer wall of clamp gripping sleeve when bonding, the c-shaped opening closure of the casing after being bonded it will send the one of tube head
End is connect with flexible axle；
S5, upper hot melt adhesive is also coated in the outer wall of casing；
S6, it is provided with magnetic induction sensor near the outer wall of leaking position of pipeline, and by magnetic induction sensor and controls
Device connection；
S7, with flexible axle by be bonded with casing send tube head be sent into pipeline, when magnetic induction sensor by controller issue letter
After number, tube head is sent in flexible axle stopping；
S8, will there is the pipeline outer wall of damaged leak site to heat, by the heating to pipeline outer wall, passes to its heat
The inner wall of pipeline, then by the way that inside pipeline the hotmelt melts on sleeve outer wall will be coated in, and by casing and give between tube head
The hotmelt melts of bonding, casing revert to c-shaped opening shape under the action of elasticity and send tube head to be detached from and be pasted onto pipeline
On inner wall；
S9, tube head will will be sent to take out out of pipeline by flexible axle.
Casing is first processed into the C-shaped opening shape casing in section, then by using flexible casing by the present invention
It is bonded in and is sent on tube head with hot melt adhesive, in the outer wall of bonding Shi Keyong clamp gripping sleeve, be closed c-shaped opening, also
It is that can be successfully sent to it inside pipeline by flexible axle so that the external dimensions of casing becomes smaller.Simultaneously in the outer of casing
