[embodiment]
Quick high-pressure no transmission stoppage urgent repair method of the present invention, the jig that has transition holding clamp and leakage stop assembly by use, the leakage stop assembly by two fastener chains 19 be connected two coupling nuts 2 between the fastener chain and 1 group of rotating threaded shaft, is fixed on leaking position of pipeline.By dry-type encapsulated bolt 11 on the leakage stop seat 9 and the 16 extruding ring-type oil resistant rubber sealings 17 of ring-type copper sheet, make leakage stop seat sealing leakage position again, leak fluid flows out by the overflow hole on the leakage stop seat 15.Then together with leakage stop seat and pipeline welding.With leakproof pipe cap 10 dry-type encapsulated nuts is passed through the welding capping again, with plug stifled 13 and overflow hole pipe cap 12 capping overflow holes.Remove the transition holding clamp at last and can finish the leak stopping of pipeline.For guarantee the leakage stop seat combine with pipeline closely, reliable, curved cylinder is matched in the bottom surface that the bottom surface of leakage stop seat and leakage stop seat are packed into behind the ring-type oil resistant rubber Sealing with the outer diameter tube surface.And after leak stopping is finished, the dry-type encapsulated bolt on the leakage stop seat and with the plug block outside the overflow hole of lid, weld a pipe cap that is used for leakproof more respectively.
The jig that is exclusively used in quick high-pressure no transmission stoppage urgent repair method of the present invention's design is made up of transition holding clamp and leakage stop assembly.Wherein:
Described transition holding clamp comprises two fastener chains 19 and is connected two coupling nuts 2 between the fastener chain and 1 group of rotating threaded shaft etc.Described coupling nut center is the trapezoidal thread that cooperates with rotating threaded shaft, and the both sides of coupling nut connect fastener chain by movable chain card 3.Described rotating threaded shaft the inner be connected the rotation very heavy in, described rotating threaded shaft the inner is provided with "T"-shaped termination, the "T"-shaped termination of rotating threaded shaft is by two the normal rated thrust ball bearings 7 and the fixing gland 4 of thrust ball bearing, and gland clamping bolt 5 is installed in the endoporus of the very heavy cover 6 of rotation.Rotation is very heavy to be combined closely with pipeline in order to make, and the bottom surface that rotates very heavy cover also is the arc cylinder that matches with the outer diameter tube surface, and the circular arc tangent plane is consistent with need leak stopping outer diameter tube.
The main body of described leakage stop assembly is a leakage stop seat 9, the leakage stop seat is detains put bowl-shape, the curved cylinder in its bottom surface, the center of described leakage stop seat is provided with overflow hole 15, and be fixed with overflow pipe nipple 14 in the outer end of overflow hole, the fixing overflow pipe nipple of described leakage stop seat be in the overflow hole outer end with welding fixed weir pipe nipple, and the overflow pipe nipple inside and outside through all being provided with screw thread.The bottom opening of the bowl-shape wall of described leakage stop seat is provided with the annular seal groove, puts into ring-type copper sheet 16 in the groove, the ring-type oil resistant rubber of packing into outside it again sealing 17.The top of described leakage stop seat ring shape seal groove also is rotary with a plurality of dry-type encapsulated bolts 11 that are used for pushing the ring-type copper sheet.The leakage stop seat of described leakage stop assembly is provided with the welding chamfering at the bottom peripheral edge place.The leakage stop seat of described leakage stop assembly also is provided with ring-type heat dam 18 in the outside of bottom ring-type seal groove, in order to guarantee the safety of leakage stop seat in welding.Two fastener chains of described leak stopping assembly and transition holding clamp are connected by the fixedly chain card 8 of leakage stop seat both sides.
The leakage stop seat can utilize multiple steel to make, and scribbles rust proof paint at the skeleton outer surface.
The present invention not under the stop status, carries out rush repair to the pipe perforation that occurs at the high pressure-temperature in-service pipeline.At first the leak stopping assembly that selection adapts according to pipeline specifications welds overflow pipe nipple 14, mounted valve at the overflow hole place.By fastener chain 19, will rotate very heavy cover 6 and covering leaks clamping and realize connecting with pipeline, pipe perforation is covered, guarantee the normal operation of pipeline internal medium.Rotating threaded shaft 1 applies pretightening force compression oil resistant rubber sealing 17 then, connects the spill pipe overflow at overflow hole 15 then.With the welding of leakage stop seat and pipeline, welding is finished the back and is removed spill pipe again, and fastener chain and rotation are very heavy, and play plug blocks up 13, covers leakproof pipe cap 10, thereby safe, efficiently finishes leak stopping and rush to repair operation.
The present invention is applicable to vertical masonry joint pipe, volute, and the quick repairing operation of weldless tube and submarine pipeline can easily be installed in the leakage stop assembly and wait to rush to repair on the pipeline.If line construction is volute or seamed pipe, also all can strengthen the pretightening force of oil resistant rubber sealing by adjusting dry-type encapsulated bolt, realize sealing.
