Specific operation mode:
Need do steel pipe 1 step-down of rushing to repair stop the supple of gas or steam (cutting off the water) band gas (cutting off the water) cut two places, each disconnected lower 6m pipeline section is as working pit; Need do with high pressure water steel pipe 1 inner wall washing rushed to repair clean, and detect one time with pipeline robot along inner-walls of duct, find that obstacle makes a record, row relax of going forward side by side; Need do the both sides, 0.5m place, steel pipe 1 outer end of rushing to repair in distance and respectively weld the doughnut-shaped steel plate that internal diameter is outer diameter of steel pipes, its width is 2 times of steel flanges dish 3 width that need make the steel pipe 1 rushed to repair; According to the operating pressure that need make the steel pipe 1 rushed to repair, select suitable steel flanges dish 3, the need being welded on stop the supple of gas or steam (cutting off the water) do on the outer wall end face of the steel pipe 1 rushed to repair, and wherein 0.8MPa needs to adopt down hill welding with upward pressure; The PE bushing pipe 12 of thick for 10mm same caliber is welded with hot-melting machine, its length is than being steel pipe 1 20mm greatly rushed to repair, and 10mm is respectively stayed in two ends, and PE bushing pipe 12 is U-shaped, connect drawing head, by winch, U-shaped PE bushing pipe 12 is moved to the operating pit of the other end from the operating pit of one end; By the method for electric heating melting, PE flange plate 4 thick for 10mm is welded on the end face of PE bushing pipe 12, makes the distance between PE flange plate 4 and steel flanges dish 3 be 10mm; Two same caliber steel pipe nipples in operating pit place connect, this steel pipe nipple side welding steel flanges dish 3, be connected with PE flange plate 4, add the rubber gasket (when 0.4Mpa is to adopt anti-high pressure steel pad during upward pressure) of GB between steel flanges dish 3 and PE flange plate 4, the other end of steel pipe nipple be fixedly welded on do not need rush to repair steel pipe 2 on; The doughnut-shaped steel plate that each welding is same on the steel pipe 2 not needing to rush to repair at distance doughnut-shaped steel plate 1m place, the upper protecting jacket of welding, form steel protecting jacket 5, allow steel mould connection set and be in closed state; In steel protecting jacket 5 upper end, gas cutting digs out a circular hole, circular hole position is just to logical button bolt and nut joint below, because pipe network running pressure is more than 0.4MPa, fluid strengthens the impact force of tube wall, tour personnel are in the patrol and detection process that pipe network is regular, if find that there is Seepage, can in time with spanner tightly logical button bolt and nut, until No leakage, at the steel pipe nipple 7 of circular hole place welding DN150, then welding flange, and add sealing gasket, assemble the Flange Ball Valves 8 of DN150 more up, finally seal up blank flange stifled 9; After entirety has been debugged, device is placed in the underground protection well 10 with brick one-tenth.
Device is all greatly improved in leakproofness, bearing capacity, working life, practicability and Security, and can detect leakproofness at any time, makes the ability of its safe operation have also been obtained very large raising; Pipeline runs in situation with pressure; especially under high pressure conditions; fluid strengthens the scouring force of pipeline, and device adds steel protecting jacket 5, for guaranteeing security of operation; blank flange stifled 9 can regularly be pulled down by tour personnel; open Flange Ball Valves 8 and detect whether have gas leakage or water leakage phenomenon, if had, logical button nut has likely loosened; bolt and nut can be detained, until No leakage in time with spanner is tightly logical.Steel pipe inner wall progress to repaired than being pasted by PE bushing pipe 12 with glue in prior art; Because prior art gluing pastes and is only applicable to the pipe network (low-pressure pipe network of as the saying goes) being less than 0.01MPa operating pressure, and the time grown, often occur that viscose lost efficacy, PE bushing pipe 12 with need do the steel pipe 1 the rushed to repair phenomenon from drum, the hole of originally gas leakage (leaking) does not do the process strengthening welding steel, so time length can continue the phenomenon that corrosion air-leakage (leaking) occurs, once gas leakage can be full of the length range that whole need make the steel pipe 1 rushed to repair, the danger of potential safety hazard and gas leakage detonation is very large, and serious consequence is beyond imagination.
The above is only preferred implementation of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
