Description
Technical field:
The present invention relates to a kind of water-soluble pipeline plug and its pipe plugging methods.
Background technique:
Currently, the pipeline of the flammable and explosive substances such as conveying natural gas, petroleum, 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
It is able to bear pressure, will result in accident as pressure breaks through butter.Because butter wall cannot bear pressure, needed before construction
A large amount of water and nitrogen is used to replace the hazardous gas of pipeline.(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, needed before construction using a large amount of water and nitrogen
Gas replaces the hazardous gas of pipeline.(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 needing 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.

The closure part passes through fixed part by connecting rod, connects postposition fastening part, tightens fastening part, match these three
Part is fitted close, and is linked into an integrated entity.And sealant is squeezed, so that sealant is filled tiny gap.
Fixed part side extension is flexible or elastic extension, and flexible or elastic extension and fixed part are axially formed
Angle is 0-90 degree.Anti-rotation groove is equipped with inside fixed part.
The postposition fastening part be it is cylindric, centre be equipped with screw thread.Fastening part is equipped with and what driving means cooperated tightens
Hole.
The 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, tightens handle and intermediate connecting rod is to stretch
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, the specific steps are as follows:
(1) cut that old pipeline is to be replaced or helpdesk cuts off by cold cut；
(2) the old pipeline inner wall of the place of cutting off two sides in step (1) is cleaned to no greasy dirt state using clean wiping cloth；
(3) according to welding when weld bond generate temperature conduction, to product temperature less than 80 DEG C, determine position first will block
Portion is mounted in pipeline.
(4) sealant is close to closure part.
(5) fixed part is pushed in turn in push-in in sequence.
(10) other end of pipeline is also carried out according to above step.
(11) place of cutting off is pushed into new pipeline in step (1)；
(12) new pipeline is weldingly connected with old pipeline.
The present invention using the above scheme, has the advantages that
(1) the dangerous pipeline such as specification conveying natural gas, conveying hazardous chemical, transfer oil is in replacement and maintenance, system
The full constructing operation specification in Dingan County.Shorten the time of fire operation, improves production efficiency.
(2) water-soluble pipeline plug and required auxiliary material are made using soluble material, can thoroughly be decomposed,
Without taking-up, pipeline will not be polluted and block, it is biodegradable not pollute the environment；
