Description
Technical field：
The present invention relates to a kind of water-soluble pipeline plug and its pipe plugging methods.
Background technology：
Currently, the pipeline of the flammable and explosive substances such as conveying natural gas, oil, after being used for a while, because of pipeline
Corrosion, replaced and repaired, replaced and need to carry out welding fire operation when repairing.When welding fire operation,
If effectively flammable and explosive substance cannot be isolated, great explosion and pyrophoricity accident will occur.In the past to pipeline
The mode blocked mainly has：（1）Butter plugging method is also referred to as butter wall：This method is pushed away in the pipe ends to need repairing
Enter a certain amount of butter, form a butter column, to play the role of blocking isolation, the disadvantage is that needing operator in the short time
Fire operation is welded in interior completion, otherwise butter meeting slump failure, and butter, which can not take out to remain in, can pollute pipeline in pipeline, no
Pressure can be born, will result in accident as pressure breaks through butter.Because butter wall cannot bear pressure, needed before construction
To use a large amount of water and nitrogen to the hazardous gas of pipeline into line replacement.（2）Ball plugging method is also referred to as spherical pig：This side
Method is respectively to place an inflatable rubber batching sphere in the pipe ends to need repairing, and cooperation butter wall together, plays closure
The effect of isolation needs to take out batching sphere after the completion of operation, the disadvantage is that allowing for taking out rubber batching sphere, in the mistake of taking-up
Cheng Zhong needs to destroy rubber batching sphere, and pipeline can be polluted while can also be on pipeline by damaging the rubber residues to fall off
Instrument result in blockage.Because this method cannot equally bear pressure, need to use a large amount of water and nitrogen before construction
Gas is to the hazardous gas of pipeline into line replacement.（3）Freeze plugging method：This method is rushed completely inside the pipeline needed replacing
Water is freezed two sections of icicles in pipeline using freezing equipment, plays the role of closure with this, the disadvantage is that being needed before operation a large amount of
Preparation needs to expend a large amount of resource, if in the cooling time that the season of high temperature needs to grow very much, and in cold area
Domain, icicle takes a long time just can thoroughly melt after the completion of operation, causes the waste in resource.

It is also stayed among closure part and fixed part after thoroughly tensing at regular intervals, it is ensured that there are sufficient overdose spaces for fluid sealant.
The interconnecting piece of the closure part is round estrade shape, and connecting rod is equipped with before round estrade shape face, is set in connecting rod
There is screw thread.
, there are multiple flexible edges at the edge that the pressure-bearing portion is contacted with inner wall of the pipe, can be with contraction distortion.Closure part round platform
Body shape structure is equipped with anti-rotation protrusion, coordinates with the groove inside fixed part, plays the purpose for preventing rotation.
The closure part passes through fixed part, connection postposition fastening part to tighten fastening part, these three is made to match by connecting rod
Part is fitted close, and is linked into an integrated entity.And crush seal glue, so that fluid sealant is filled tiny gap.
The fixed part lateral edge is interval cyclic annular flexible barbs edge.Fixed part is internally provided with anti-rotation groove.
The postposition fastening part is cylindric, and centre is equipped with screw thread.Fastening part is equipped with and what pusher coordinated tightens
Hole.
The fluid sealant is that ready-made disk is cyclic annular.
The installation tool is made of two pan heads and a handle.The head of front is equipped with to be connected with fastening part
The protrusion auxiliary section connect.The head of back plays the role of to stablize in pipeline, and it is that can stretch to tighten handle and intermediate connecting rod
Contracting design, do not influenced by mounting distance, handle is far pulled outwardly by product mounting distance away from pipeline opening, otherwise mounting distance proximad in
It pushes away.
Use during pipeline maintenance of the plugging device, is as follows：
（1）Cut that old pipeline is to be replaced or helpdesk cuts off by cold cut；
（2）Using clean wiping cloth by step（1）In the old pipeline inner walls of the place of cutting off both sides clean to no greasy dirt state；
（3）According to the temperature conduction that weld bond when welding generates, the temperature to product is less than 80 DEG C, determines that position will first block
Portion is mounted in pipeline.
（4）Fluid sealant is close to closure part.
（5）Fixed part is pushed in turn in push-in in sequence.
（10）The other end of pipeline is also carried out according to above step.
（11）To step（1）In the place of cutting off be pushed into new pipeline；
（12）New pipeline is weldingly connected with old pipeline.
The present invention using the above scheme, has the following advantages that：
（1）Specification conveys the dangerous pipelines such as natural gas, conveying hazardous chemical, transfer oil in replacement and repair, system
The full constructing operation specification in Dingan County.Shorten the time of fire operation, improves production efficiency.
