Abstract
The utility model discloses a releasing hoop blocking device for pipelines under pressure, which is suitable to the blockage of the oil pipeline under pressure in an oil field without stopping production. The device comprises a main body, a cap nut, a central top rod, a packing press cap, and a sealing packing, wherein the sealing packing and the packing press cap are arranged in the main body and are fixed by the cap nut. The lower end of the central top rod is provided with a wedge which can pass through the sealing packing and the packing press cap and move up and down in the main body. The utility model can detach the theftproof sealing hoop under pressure on normal pressure for carrying out the operation of welding repair. The utility model has the advantages of high safety, quick speed, less environmental pollution and simple operation and the stop production can not occur caused by the welding of a leakage point. The pressure in the pipeline can be discharged, and the normal process of the production and the personal safety of workers can be ensured.
Description
Technical field
The utility model relates to the leak stopping repair welding equipment in line transportation field, and particularly pipe pressurized releasing hoop leakage-baffling device is applicable to that the band of oil field oil transport pipeline is pressed the releasing hoop plugging operations that do not stop production.
Background technique
On the defeated Zhi Ganguan road of crude oil collection, the lawless person usually installs the whole cassette sealing clip that has the fire ball valve in order to steal national crude oil on oil transport pipeline, the seal section drilling hole of oil stolen or on the low pipeline of pressure direct drilling hole of oil stolen.In order to repair ruined oil transport pipeline, field produces unit often is forced to and will the oil transport pipeline stopping production of theft with the sealing clip be installed, release the pressure in the pipeline, remove the sealing clip again and carry out the soldering operation, or carry out soldering again after the less pipeline of pressure emitted the manual stifled timber wedge of spray.Not only influence ordinary production and workmen's personal safety is had bigger danger, produce to the oil field and brought enormous economic loss.
Summary of the invention
The purpose of this utility model provides pipe pressurized releasing hoop leakage-baffling device, improves present pipe plugging mode, it can be with on the normal pressure pipeline press the removal clip and carry out the soldering operation, guarantees ordinary production, reduces production costs.
Use the present technique solution can reach above-mentioned purpose: pipe pressurized releasing hoop leakage-baffling device comprises body, cap nut, center push rod, packing pressure cap and sealed packing, and sealed packing and packing pressure cap are installed in the body, are fixed by cap nut; Push rod lower end, center installation chock can pass sealed packing and the packing pressure cap is up and down in body.
The utility model can carry out the soldering operation after band on the normal pressure oil transport pipeline is pressed the leak stopping of removal clip.Have safe and convenient, reduce environmental pollution, advantage simple to operation.The band that can be widely used on oil field individual well oil transport pipeline and the oil transportation service main pipeline is pressed the operation of removal clip, need not to be forced to stop production for the soldering leak source, releases the pressure in the pipeline.What guaranteed to produce normally carries out personal safety with the workman.The utility model also can be used for the leak stopping soldering operation under other conveyance conduit same case.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description: referring to accompanying drawing, pipe pressurized releasing hoop leakage-baffling device comprises body 1, cap nut 3, center push rod 4, packing pressure cap 5 and sealed packing 6, sealed packing 6 and packing pressure cap 5 are installed in the body 1, and be fixing by cap nut 3.Push rod 4 lower ends in center install that chock 2 can pass sealed packing 6 and packing pressure cap 5 is up and down in body 1, chock 2 with wooden be best.Body 1 is a cylinder, and the two ends external diameter is provided with screw thread, and the top internal diameter is provided with step sealed packing 6 and packing pressure cap 5 are installed.Body 1 also is provided with the release outlet and is communicated with body 1, and the release outlet is gone up release plug 7 is installed.
During on-the-spot the use, chock 2 and center push rod 4 are connected, the quick ball valve of the sealing clip installed on body 1 lower end and the stolen pipeline is connected, and guarantees that the joint seals.The ball valve of sealing clip is opened to fully open position, and the center push rod 4 of transferring this device makes chock 2 pass the ball valve of sealing clip and is connected pipe nipple, aims at and seals the interior pipeline eyelet of clip.Then center push rod 4 is applied impact force chock 2 is pounded tightly, block leak source.Unclamp the release plug 7 on this device, check whether leak source is blocked.Lay down the sealing clip on the pipeline after blocking, promptly finish band and press the sealing clip leak stopping work of unloading.The part that leaks outside of blocking the chock 2 of leak source is cut off, the metal patch of making is placed on position suitable on the leak source.Patch hold down gag or general tool with special use compress patch, and be with electric welding that patch and pipeline welding is firm.
