Description
Technical field
The present invention relates to the leakage stopping technology of gas pipeline, in particular to the blocking method of a kind of gas pipeline and realization should
The device of method.
Background technique
With the continuous improvement of living standards, requirement of the people to house interior decoration is higher and higher, and building gas pipe, service pipe, indoor pipe
System of laying directly influence the decorative effect of Indoor Residential Ecological.Since gas pipeline secretly buries, after pipeline leaks,
It is not easy to be found, and relatively difficult to leakage failure processing, this is just that the safety of gas pipeline has buried hidden danger.
Currently, in the prior art, in the Chinese patent document that Authorization Notice No. is CN101900238B, describing
A kind of gas pipeline is not stopped the supple of gas or steam the blocking method not welded, and the soft sealed briquette matched with leakage point size, placement are selected
Between the arc compact heap of device for plugging and the leakage point of gas pipeline, by rotating the housing screw of device for plugging, compress
Screw pushes arc compact heap to move radially, and arc compact heap pushes soft sealed briquette to be pressed on leakage point, until soft close
Envelope briquetting blocks leakage point completely, screws the fine tuning backing-up screw on device for plugging, and fine tuning backing-up screw acts on arc compression
It on block, is pressed on soft sealed briquette by arc compact heap, by the pressure of housing screw and fine tuning backing-up screw, is made soft
Sealed briquette is pressed on leakage point.
Above-mentioned this blocking method, which mainly rotates adjusting fine tuning backing-up screw, makes soft sealed briquette be pressed on leakage point
On, still, since gas pipeline is often embedded in underground, fine tuning backing-up screw is easy to be generated pine by the corrosion of corrosive fluid
It is dynamic, secondary let out is easy to happen after leak stopping for a period of time so as to cause compression decreased effectiveness of the sealed briquette on leakage point
Leakage.
Summary of the invention
The first object of the present invention is to provide a kind of blocking method of gas pipeline, remains applied to the pressure on compact heap
Power compresses significant effect, is not likely to produce secondary leakage to remain the pressing force to leakage.
Above-mentioned technical purpose of the invention has the technical scheme that a kind of leak stopping side of gas pipeline
Method, the leakage point for including the following steps: a, finding out gas pipeline, by leakage point surrounding conduit preservative substance, iron rust and
Impurity is cleaned out；
After step a, also in turn include the following steps:
B, the device for plugging that selection is matched with gas pipeline diameter covers the soft ontology winding of device for plugging
On gas pipeline, first end and the second end are fixed together, soft ontology and gas pipeline are arranged fastening, soft ontology
On seal and the outer circumference surface of gas pipeline fit closely, seal soft ontology and combustion gas on soft body width direction
Gap between pipeline makes to form closed cavity between soft ontology and gas pipeline, and the compact heap on device for plugging is corresponding
It is covered on leakage point, mitigates the outside gas leakage of leakage point；
C, the air valve on gas nozzle is opened, is inflated by way of squeezing rubber ball into air bag, makes the compact heap on air bag
Be pressed on leakage point, seal leakage point, into air bag constantly inflation until compact heap seal leakage point completely, be then shut off gas
Valve is pressed on leakage point with keeping air bag to pass through compact heap always.
By using above-mentioned technical proposal, device for plugging adapter sleeve is set to the surrounding of the leakage point of gas pipeline, repairing
Personnel are inflated by way of squeezing rubber ball into air bag, and the compact heap on air bag is made to compress leakage point, live to leak with leak stopping
Point, makes leak point no longer leak combustion gas, applies pressure leak stopping leakage point by air bag, so that leak stopping is got up more convenient, laborsaving, gas
Capsule is closed by air valve, remains the pressure being applied on compact heap, to remain the pressing force to leakage, it is aobvious to compress effect
It writes, is not likely to produce secondary leakage.
Further, further include step d after step c: detecting whether detection mouth has gas leakage by coal gas detection instrument
Out, if detection mouth has gas leakage to come out, device for plugging leak stopping is reinstalled, if detection mouth comes out without gas leakage,
Detection mouth is closed by closing cock, completes plugging operation.
By using above-mentioned technical proposal, after leakage point is lived in leak stopping, repair personnel detects inspection using coal gas detection instrument
The case where whether combustion gas surveyed at mouth leaks, and realization is accomplished to check, compact heap is avoided not block leakage point to plugging operation
Occur, ensures that leakage work is up to standard, if there is combustion gas to leak out from detection mouth, reinstall the position of device for plugging, with
Realize the leak stopping to leakage point.
The second object of the present invention is to provide a kind of device for plugging, to the leak stopping of leakage point operation enhanced convenience, laborsaving,
And preferable plugging effect can be remain.
Above-mentioned technical purpose of the invention has the technical scheme that leak stopping side described in a kind of realize
The device for plugging of method covers the soft ontology on gas pipeline including winding, and the soft body internal surface is provided with several
