Abstract
The utility model relates to a U-shaped pipeline leakage-stopping plug used for repairing a seriously-eroded pipeline online without production halts or hot work. The utility model is characterized in that an arc steel plate is fastened with a U-shaped connecting arm to form an annular connecting body. The arc steel plate is provided with an engaging lug on both ends and the engaging lug is provided with a via hole for a bolt. A rubber plate for stopping leakage is embedded inside the arc steel plate and a screw thread is respectively arranged on both ends of the U-shaped connecting arm. The U-shaped pipeline leakage-stopping plug used for repairing a seriously-eroded pipeline online without production halts or hot work has the advantages that the utility model can be applied in the following situations: firstly, the pipeline leaks due to corrosion and perforation, but the eroded pipeline fails to be replaced due to the fact that production is not to be halted. Therefore, an online pressurized leak stoppage is needed; secondly, an online pressurized leak stoppage is necessary in the first-grade fire-forbidden fire district. After the leaking point of the pipeline is blocked and corrosion-resistant treatment is done, the leakage fails to reappear due to time. As the leakage-stopping plug is integrated with the rubber for stopping leakage, the leakage-stopping plug is easy to be put in place and does not affect the blockage speed despite the fact that the medium has a high pressure, the oil is smooth and the water is hot inside the pipeline.
Description
Technical field
The utility model belongs to the corrosion pipeline repair outfit, relates in particular to a kind of online reparation that is applied to not stop production, do not get angry on the pipeline of heavy corrosion pipeline U type leak stopping card.
Background technique
All kinds of embedded metal pipeline overwhelming majority in the industrial field are operated in the media such as the great soil of corrosivity, the military service buried pipeline all has corrosion in various degree for a long time, thereby reduced the usability of metal construction, shortened service life, maintenance just needs stop work and production, also has a great potential safety hazard simultaneously.Widespread usage is to adopt machining fixture high-pressure injection plastic or steel band tension leak stopping or two halves big-ear clamp in the leak stopping means of seriously corroded perforation leakage at present.The problem that exists: 1, machining fixture high-pressure injection plastic method: (1) long construction period, cost height, next step operation construction of the big inconvenience of profile.(2) instability of fed sheet of a media pressure in the pipeline often causes repeatedly seepage again, needs injecting glue repeatedly.2, steel band tension blocking method: (1) because steel band and iron plate, rubber are separate splits, in executing stifled process, reasons such as pipeline internal medium pressure is big, cunning, hydro-thermal, be difficult to set upright execute fast stifled.(2) steel band is executed in the stifled process in reinforcing, because pulling force causes the variation of steel band stress Organizational Structure, owing to be that the time one grows now and relaxs one's efforts, ruptures, and causes phenomenons such as seepage by jackscrew locking.3, two halves big-ear clamp method: owing to be that two halves semicircle steel plate is formed, need execute at the scene when blocking up and assemble once more, so it is slow to execute stifled speed, and the both sides ear is too big, is not easy to next step reinforcement and preservative process and handles.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of pipeline U type leak stopping card is provided, and during online reparation, can not get angry, do not stop production, withstand voltage height, online pressure sealing, using method is easy, it is fast to execute stifled speed, and economical with materials is in light weight, ensures construction safety.
The utility model for achieving the above object, by the following technical solutions: a kind of pipeline U type leak stopping card, it is characterized in that: mainly be buckled into circular connector by curved plate and U type link arm, described curved plate two ends are provided with engaging lug, engaging lug is provided with the bolt via hole, be inlaid with the leak stopping rubber plate in the curved plate, described U type link arm two ends are provided with screw thread.
Described curved plate is provided with the aperture of fixedly leak stopping with rubber plate.
Folding has sealing strip around the described curved plate.
Described leak stopping is adopted the rubber plate special-purpose high temperature resistant, that oil resistant is dirty with rubber plate, and the rubber plate outer surface is provided with fixedly uses projection.
The beneficial effects of the utility model: can effectively be applied in following several situation: the corrosive pipeline perforation is leaked, but because production needs not allow again to stop production, can't change the pipeline section that has corroded, needs online pressure sealing; Forbid the first class fire prevention division of getting angry, can online pressure sealing; After blocking pipe leakage point, through preservative treatment, can be owing to seepage appears in time relation again: covering leaks clamping and leak stopping rubber be one, can be not big, cunning, reason such as hydro-thermal because of pipeline internal medium pressure, and be difficult to set upright and influence the stifled speed of executing.

Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.
As shown in the figure, a kind of pipeline U type leak stopping card, mainly be buckled into circular connector by curved plate 1 and U type link arm 2, described employing 3-8 millimeters thick curved plate two ends are provided with engaging lug 3, engaging lug is provided with bolt via hole 4, be inlaid with leak stopping in the curved plate with rubber plate 5, adopt the U type link arm two ends of φ 14mm round steel to be provided with screw thread, the diameter of U type link arm round steel can be according to leak stopping card length setting.Repaiied the size of plugging road diameter, it is fixed that the covering leaks clamping size of processing is come.U type link arm and engaging lug quantity are provided with 8 millimeters apertures 6 of two or more fixedly leak stopping sealed rubber plates according to described curved plate.The rubber plate outer surface is provided with 8 millimeters high 6 millimeters rubber projections 9 of two or more diameters, behind the insertion aperture 6, plays the fixedly effect of rubber plate.Folding has 5 mm wides that the sealing strip 8 of radian is arranged around the described curved plate, can stop the resin binder of smearing to enter the curved plate internal surface and combine (rubber plate and metal tube are that its bonding effect of different materials is poor) with rubber plate, thereby guarantee the pipeline section good bond of pipeline U type leak stopping card and corrosion.Described leak stopping rubber plate adopts the rubber plate special-purpose high temperature resistant, that oil resistant is dirty, is used for the shutoff corrosion surface.Curved plate is crossed nut 10 with U type round steel cartoon and is connected.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
