Abstract
A leak stopper for an oil delivery pipe belongs to the technical field of oil fields, and solves the problems that the maintenance of the present oil pipeline has the disadvantages of low probability of operation, low operating efficiency and potential safety hazard. The leak stopper comprises an upper pipe hoop (1) and a lower pipe hoop (2), wherein pin holes are formed at one end of the upper pipe hoop (1) and one end of the lower pipe hoop (2) which are movably connected through a pin shaft (3), and screw holes are formed at the other end of the upper pipe hoop (1) and the other end of the lower pipe hoop (2) which are fixedly connected through a fastening bolt (4). The leak stopper is characterized in that grooves are formed on the inner surfaces of the upper pipe hoop (1) and the lower pipe hoop (2), and sealing gaskets (5) are fixed in the grooves. The leak stopper for the oil delivery pipe has the advantages of good sealing effect, simple operation, high plugging efficiency and excellent safety performance.
Description
Technical field
The utility model belongs to the oilfield technology field, is specifically related to a kind of leakage-baffling device that is used for oil field pipe.
Background technique
The oil field is in oil recovery process, and the former oil require of exploiting out is transported to metering room, terminal and multi-purpose station by petroleum pipeline.Petroleum pipeline is buried in underground usually, and through using for a long time, the situation of missing or boring a hole will appear in the pipeline part.In case this situation occurs, come the pipeline that leakage or perforation occur is carried out the leak stopping maintenance with regard to the team that needs repairing.Existing pipe repairing method normally adopts the method for electricity, gas welding to carry out, because that petroleum pipeline is embedded in is underground, the position is lower, inconvenient workman operation; Oil in pipeline, G﹠W are difficult for being drained by complete emptying, bring difficulty and danger can for workman's electricity, the operation of gas welding maintenance construction, greatly progress, quality and the construction safety of influence electricity, the construction of gas welding maintenance operation.
The model utility content
The purpose of this utility model be for the maintenance that solves existing petroleum pipeline exist not easy to operate, efficiency of construction is low and have the problem of potential safety hazard, and provides a kind of transport pipe leak stopping device.
This transport pipe leak stopping device is made up of last pipe collar, following pipe collar, one end of last pipe collar reaches down, and an end of pipe collar is provided with pin-and-hole, and flexibly connect by bearing pin, the other end of last pipe collar reaches down, and the other end of pipe collar is provided with screw, and it is fixedly connected by clamping bolt, it is characterized in that: the internal surface of pipe collar had groove under upward pipe collar reached, and the groove internal fixation has sealing gasket.
This transport pipe Plugging device has following beneficial effect:
Last pipe collar is flexible connection with following pipe collar one end, and both realize opening and closure of transport pipe leak stopping device by rotating around bearing pin, thereby the convenient construction personnel are enclosed within transport pipe leak stopping device on the petroleum pipeline.The internal surface of pipe collar had groove under last pipe collar reached, and the groove internal fixation has sealing gasket; During construction sealing gasket is aimed at the leak source of petroleum pipeline, then clamping bolt is tightened, transport pipe leak stopping device is bound round securely on petroleum pipeline, the pressure that it produced can make sealing gasket fully contact and form the good face that is sealed and matched with the petroleum pipeline surface, thereby reaches the purpose of effective shutoff leak source.
Good, simple to operate, the shutoff efficient height of this transport pipe leak stopping device plugging effect, owing to do not need electricity, gas welding, so Safety performance is good.
Description of drawings
Fig. 1 is an overall structure sectional view of the present utility model.
The last pipe collar of 1-; Pipe collar under the 2-; The 3-bearing pin; The 4-clamping bolt; The 5-sealing gasket.
Embodiment
The utility model is described in further detail below in conjunction with embodiment:
This transport pipe leak stopping device is made up of last pipe collar 1, following pipe collar 2, one end of last pipe collar 1 reaches down, and an end of pipe collar 2 is provided with pin-and-hole, and by bearing pin 3 flexible connections, the other end of last pipe collar 1 reaches down, and the other end of pipe collar 2 is provided with screw, and it is fixedly connected by clamping bolt 4, it is characterized in that: the internal surface of pipe collar 2 had groove under upward pipe collar 1 reached, and the groove internal fixation has sealing gasket 5.
The last pipe collar 1 of this transport pipe leak stopping device is flexible connection with following pipe collar 2 one ends, and both realize opening of transport pipe leak stopping device and closed by centering on bearing pin 3 rotations, thereby the convenient construction personnel are enclosed within transport pipe leak stopping device on the petroleum pipeline.Last pipe collar 1 and down the radian of the internal surface of pipe collar 2 should be processed into identically with the radian of petroleum pipeline outer surface, purpose is to make that it fully contacts with petroleum pipeline, fixation.The internal surface of pipe collar 2 had groove under last pipe collar 1 reached, and the groove internal fixation has sealing gasket 5, and sealing gasket 5 can be made by oil resistant rubber or teflon; During construction sealing gasket 5 is aimed at the leak source of petroleum pipeline, then clamping bolt 4 is tightened, transport pipe leak stopping device is bound round securely on petroleum pipeline, the pressure that it produced can make sealing gasket 5 fully contact and form the good face that is sealed and matched with the petroleum pipeline surface, thereby reaches the purpose of effective shutoff leak source.
When leakage or perforation take place and need leak stopping in petroleum pipeline, at first to close oil-feed and fuel-displaced valve, the pipeline that leakage or perforation take place is dug out, and find out leakage points; Remove the thermal insulation layer on the leakage points place pipeline external wall,, the sealing gasket of last pipe collar 1 or following pipe collar 2 is aimed at leak source, be stuck on the petroleum pipeline then according to the position of leak source in pipeline top or bottom; With spanner clamping bolt 4 is tightened again, oil, gas, water in the pipeline can not be spilt from pipeline.Open the oil-feed valve pressure testing of petroleum pipeline, no longer include oil in the pipeline, when seepage goes out, be leak stopping and complete successfully.Again the pipeline that digs out is buried again, open turnover fuel tap door, return to normal production.
Good, simple to operate, the shutoff efficient height of this transport pipe leak stopping device plugging effect, owing to do not need electricity, gas welding, so Safety performance is good.
