Abstract
The utility model relates to a pipeline leak repairing and emptying device for repairing and maintaining underground gathering and transportation pipelines such as petroleum, chemical engineering, water supply and the like, which is composed of a pipe joint (1), a reducing joint (2) and a stop valve (3) in threaded connection. The device simple structure, convenient and practical has solved the shortcoming that the welding bottom weeping hole need be put fluid in the pipe to the greatest extent when secret gathering and transportation pipeline mends the hourglass, utilizes it to shorten the time of mending the hourglass greatly, guarantees gathering and transportation pipeline normal production operation.
Description
The utility model relates to a kind of mending-leakage evacuating device that is used for the underground gathering line repair maintenance of industry operations such as oil, chemical industry, water supply.
The underground gathering line of industries such as oil, chemical industry, water supply uses through long-term, and because of being subjected to inside and outside medium acting in conjunction, local pipeline section corrosion failure phenomenon happens occasionally.At present, when underground gathering line generation corrosion failure is repaired, need the emptying of pipeline inner fluid.And exhausting pipeline method commonly used is to open a leakage opening drainage in the bottom of pipeline, and liquid level descends, and welds after the position that repair is exposed.Treat that tube fluid flows to end, again the leakage opening welding of bottom is shut, finish patch work.This kind repairing work stopping transportation time is long, influences the ordinary production operation of gathering line.
Thereby being to provide a kind of, the purpose of this utility model can shorten the blocking Leakage evacuating device that the mending-leakage time guarantees the operation of gathering line ordinary production greatly.
The purpose of this utility model is achieved in that this device is made up of pipe joint, reducer union, stop valve, position between reducer union is placed in the middle, and the bigger end of its external diameter is connected with stop valve with pipe joint with screw thread respectively with the less end of external diameter.When a certain position of underground pipeline takes place to leak, near the leaking position of pipeline upstream pipe joint is being welded on duct bottom, pass the pipe joint endoporus this moment and use gas welding, the fluid in the discharge conduit in the duct bottom perforate.After liquid level is exposed at position to be repaired, can implement repair operation.After repairing is finished, reducer union and the stop valve that has connected in advance is screwed on the pipe joint, stop valve is in open mode all the time in the process of twisting, and the interior remaining fluid of pipeline can be flowed out and unlikely building the pressure smoothly.After having twisted reducer union, stop valve is closed, this moment, repairing pipe work all finished, and can drop into proper set and transport row again.
The utility model is simple in structure, convenient and practical, utilize this no matter to install in the pipeline whether liquid is arranged, as long as liquid level can be exposed in the position of repairing, can implement the mending-leakage operation, after mending-leakage finishes, no matter whether have the liquid also can be in the pipeline the leakage opening sealing of being opened, thereby can shorten the mending-leakage activity duration greatly, guarantee that gathering line production normally moves.
Accompanying drawing is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, the utility model is made up of pipe joint 1, reducer union 2, stop valve 3.Wherein pipe joint 1 is connected an end with pipeline to be repaired and is circular arc, is convenient to coincide, weld with pipeline, and the end that links to each other with reducer union is provided with the internal thread that matches with it.Reducer union is provided with central duct, and bigger end of its external diameter and the less end of external diameter are respectively equipped with the external screw thread that matches with pipe joint 1 and stop valve 3.Stop valve 3 employing standards 6/8 " stop valve.
Claims (3)
1, a kind of blocking Leakage evacuating device, it is made up of pipe joint (1), reducer union (2) and stop valve (3), it is characterized in that: reducer union (2) occupy the neutral position, and the bigger end of its external diameter is connected with screw thread with stop valve (3) with pipe joint (1) respectively with the less end of external diameter.
2, blocking Leakage evacuating device according to claim 1 is characterized in that: pipe joint (1) is connected an end with pipeline to be repaired and is circular arc, and the end that links to each other with reducer union (2) is provided with internal thread.
