Description
Technical field：
It the utility model is related to a kind of explosion-proof pipe plugging erecting device.
Background technology：
At present, the pipeline of the flammable and explosive substances such as natural gas, oil is conveyed, after being used for a while, because pipeline
Corrosion, it is necessary to changed and repaired, change and need to carry out welding fire operation when repairing.When welding fire operation,
If effectively can not isolate to flammable and explosive substance, great blast 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 post, to play a part of closure isolation, shortcoming is to need operator in the short time
Interior to complete welding fire operation, otherwise butter meeting slump failure, butter, which can not take out to remain in, can pollute pipeline in pipeline, no
Pressure can be born, accident is will result in as pressure breaks through butter.Because butter wall can not bear pressure, needed before construction
Substantial amounts of water and nitrogen is used to enter line replacement to 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, coordinates butter wall together, plays closure
The effect of isolation, need to take out batching sphere after the completion of operation, shortcoming is to allow for taking out rubber batching sphere, in the mistake of taking-up
, it is necessary to destroy rubber batching sphere in journey, damaging the rubber residues to come off can pollute while can also be on pipeline to pipeline
Instrument result in blockage.Because this method can not equally bear pressure, substantial amounts of water and nitrogen are needed to use before construction
Gas enters line replacement to the hazardous gas of pipeline.(3) freeze plugging method：This method is that punching is full inside the pipeline for needing to change
Water, two sections of icicles are freezed in pipeline using freezing equipment, closure is played a part of with this, shortcoming is needed largely before operating
Preparation is, it is necessary to expend substantial amounts of resource, if the cooling time for needing to grow very much in the season of high temperature, and in the area of cold
Domain, icicle takes long enough just can thoroughly melt after the completion of operation, causes the waste in resource.(4) water-soluble pipe plugging
Device：A kind of duct closing type device that can meet water decomposition.By lock glue sealing ring, water-soluble fluid sealant, closure mainboard, supporting plate etc.
Composition.Lock glue sealing ring offsets with closure mainboard, lock glue sealing ring and the groove for blocking mainboard, fills water-soluble fluid sealant, plays
The purpose of slight gap between sealing blocking mainboard and inner-walls of duct.Supporting plate side flushes with closure mainboard, opposite side adhesion
Onto inner-walls of duct, play a part of fixed pressure-bearing.The program is safe and effective, with pressure-bearing but also pipeline can need not only be grown
Time nitrogen displacement.All material is water-soluble material, and a whole set of closure dress can be removed by being washed by water after the completion of piping foundation welding
Put, pipeline will not be polluted.But requirement of the program to installation is very high, especially former pipeline only cut one it is narrow and small
During position, narrow space installation operation personnel can not operate, it is difficult to ensure installation quality.Prior art does not solve to this
Plan.
