Background technology
At present, after the pipe perforation of petrochemical industry, pipe plugging method is: after stopping production, emptying, nitrogen displacement, adopts and cuts off perforated section pipeline, weld new pipeline. There is the problem that the production line using this perforation pipeline stops production, production and operation impact is huge; Use tank car to take up perforation exhausting pipeline liquid, and carry out nitrogen displacement; Need fire operation, cutting poling pipeline section, weld new pipeline section, there is bigger fire, risk of explosion; ; Fire operation narrow space, it is impossible to welding quality, overall compressive resistance reduces; Perforation place mostly is the most corrosion-prone pipeline section, and the irony pipeline after replacing is still easily corroded and again bores a hole; Pipeline for glass steel material, it is necessary to whole replacing, wastes a large amount of manpower and materials; Cross-operation is many, and construction quality cannot ensure.
Summary of the invention
Present invention seek to address that above-mentioned prior art Problems existing, and provide one to stop production, can Operating Pressure, on producing without impact, without emptying, nitrogen displacement, without fire operation, stop the petrochemical industry pipe special leak stopping emergency control method of fire, support risk.
This invention address that described problem the technical scheme is that
A kind of petrochemical industry pipe special leak stopping emergency control method, carries out in the steps below:
Step one, a leak stoppage device is used to block pipeline leak source: (1) leak stoppage device is tied up circle by the rustless steel wedge shape that grease proofing, acid-proof, high voltage bearing wedge-type seal silica gel ring and shape are contrary and formed, wedge-type seal silica gel ring is wrapped in leak source Near Pipelines, then ties up circle in wedge-type seal silica gel ring outer wrap rustless steel wedge shape; (2) wedge-type seal silica gel ring and rustless steel wedge shape are tied up circle entirety and shifts to leak source, cover leak source;
Step 2, use enhancement mode fixed cover joint, it is fixed on perforated pipe line segment, form permanent leak stopping structure: the greasy dirt on pipeline around a leak stoppage device, foreign material are cleaned out by (1), and polish pipeline with hairbrush, make pipeline surface present matte surface, then tighten disposable leak stoppage device and surrounding pipeline with high intensity pressure sealing adhesive tape;(2) pressure leakage-stopping glue of uniform application suitable depth on the pipeline near high intensity pressure sealing adhesive tape outside and leak source, again enhancement mode fixed cover joint is enclosed within winding high intensity pressure sealing adhesive tape and smears on the pipeline of pressure leakage-stopping glue, it is fastened and fixed set joint, forms permanent leak stopping structure.
Adopting the present invention of technique scheme, compared with prior art, it provides the benefit that:
1. need not stop production, can Operating Pressure, on produce without impact;
2. without operations such as emptying, nitrogen displacements;
3. without fire operation, fire, support risk are stopped;
4. the compressive resistance of high intensity special glue can reach 35mpa, additional enhancement mode fixed cover joint (multiple pressure rating is optional), and the pipeline section compressive resistance after process will be greater than former line sections;
5. special glue anticorrosion, acid and alkali-resistance, the pipeline section anti-corrosive properties after replacing substantially exceed irony pipeline;
6. special glue can be used on irony pipeline, glass steel pipeline, pvc pipeline, directly leak source can be carried out gluing leak stopping for glass steel material pipeline, need not change whole piece pipeline;
All kinds of indexs such as 7. many without cross-operation, the pipeline after reparation is pressure, anticorrosion are above former line sections.
As preferably, the present invention further technical scheme is:
Described enhancement mode fixed cover joint, including liner, lining and overcoat; Described overcoat is made up of the circular slab with gap, and described lining is arranged on the circular slab opening position of overcoat, and the circular slab of lining and overcoat forms a radially adjustable annulus closed, and described inside lining filling is in annulus; Also include retainer ring, fixing axle, screw bolt and nut; Described retainer ring includes connecting ring and connecting plate, the connecting plate of a pair retainer ring is separately fixed on the outer wall of circular slab opening position of overcoat, the connection ring set of retainer ring is on fixing axle, and fixing axle is relatively fixed ring and rotates, and retainer ring is longitudinally provided with multiple screw mounting groove; Fixing axle is axially arranged with the screw hole corresponding with the screw mounting groove of retainer ring; Described screw bolt and nut connects two fixing axles of opening position, is tightened up or unclamp the gap size of overcoat by adjusting nut.
