Description
Technical field:
The present invention relates to a kind of oil-gas pipeline fast plugging devices, and in particular to one kind is based on thermit reaction to leakage pipe
Carry out the device of quick blocking.
Background technique:
Oil and gas industry is the lifeblood industry of relationship country survival and development, and the pipeline of oil gas is petroleum
The most important means of transportation of industrial and commercial bank's industry, thus it is guaranteed that the safe and highly efficient operation of oil-gas pipeline system is to guarantee petrochemical industry
Safety and stability and country long term growth have great significance.Due to the natural calamities such as burn into landslide, Yi Ji
Tripartite's destruction etc. can all lead to the generation of pipe leakage accident.Gas oil pipe leakage is in addition to causing very huge economic loss and environment
Pollution is outer, can also cause fire, explosion accident, seriously jeopardize people life property safety.
The method that pipe leakage common at present blocks has:
(1) pipeline shutdown reparation: needing to carry out stopping transportation reparation for the oil-gas pipeline for leaking extremely serious, though this method
Right safety is higher, but will cause huge economic loss, and pipeline restarts that process is more, the duration is very long after the completion of repairing, and removes
Significant leakage does not have to the method generally.
(2) press and open holes blocking technology: mechanical three-way, sandwich valve and tapping machine are installed in pipeline section two sides to be repaired, utilized
Tapping machine carries out pipeline tapping operation, is then injected into block head and completes to block；The fluid media (medium)s such as oil gas continue from bypass pipe at this time
Flow further downstream proposes block head after the completion of the reparation of former pipeline section, restores the operation of former pipeline, finally removes related accessories.Band
Pressure venting techniques now apply comparative maturity, have many advantages, such as on-line production reparation, guarantee production, reduce economic loss, shorten the construction period,
But need to the aperture on former pipeline, the sealing performance of block head is unable to get guarantee, and plugging holes safety is not high, and meeting after repairing
Leave piece attachments.
(3) intelligent blocking technology: intelligent plugging device enters from pipeline service end, travels forward under medium effect in pipe,
Predetermined position is reached, under ultra-low frequency electromagnetic signal (ELF) instruction, anchor itself mechanism and sealing mechanism completion are set, to be repaired
It returns to work after the completion of work, withdraws anchor mechanism and sealing mechanism under ELF instruction, reached under the promotion of medium in pipe and receive ball end,
To complete whole process flows.Intelligent blocking technology is not necessarily to aperture, but the closure of this technology is at high cost, it is with pressure stifled to cannot achieve
Leakage.
(4) fixture maintenance technique: in leaking position of pipeline installs fixture, forming sealing cavity by fixture and leakage position,
To achieve the purpose that plug leak original pipe-repairing.Fixture maintenance is primarily adapted for use in pressure lower, the lesser pipe of leakage path
The temporary plugging in road；Its advantage is that easy to operate, maintenance cost is low, but surface smoothness to pipeline and ovality require compared with
Height is limited by sealing material, is not suitable for the closure of elevated pressures, there is risk of leakage again.
Existing blocking technology common problem is to block and require height, blocking time long operator, be unfavorable for letting out
The quick control of leakage accident.
Of the existing technology in order to overcome the problems, such as, the present invention is cleverly by thermit reaction and pipe plugging reinforcing device phase
In conjunction with proposing a kind of pipeline fast plugging device based on thermit reaction.The present invention can be under the premise of pipeline on-line production
Leakage part on pipeline is blocked, has many advantages, such as that simple to operate, sealing intensity is high, sealing effect is good, it can be real
The quick permanent closure of existing pipe leakage.
