Abstract
The invention discloses a pipeline cleaner which comprises two straight leather cups (1, 2), two disk leather cups (3) and a shaft bracket, wherein the diameter of the first straight leather cup (1) is slightly less than that of the second straight leather cup (2), the edge of the circumference of the second straight leather cup (2) is provided with a chamfer angle with a certain angle, and the outer circumferences of the straight leather cups are symmetrically provided with at least two holes (4). The invention increases the passing property in a pipeline of the pipeline cleaner, and is not easy to occur in the blockage during the pipeline cleaning construction.
Description
Technical field
The present invention relates to be used for the equipment that pipeline pigging work progress is used in a kind of industrial gas oil, be specially pipeline cleaner.
Background technology
Regulation and the standard relevant according to country, need oil and gas pipeline is carried out pigging and testing, by pipeline is detected, in time obtain the first-hand scientific information of pipeline good working condition at the pipeline initial stage of building up, in time find pipeline make, anticorrosion, laying stage is because defect of pipeline such as the construction operation mechanical damage that causes lack of standardization, weld seam abnormity point carry out necessary reparation and strick precaution; Can be with this as acceptance criteria to pipeline quality, the more important thing is in order to compare with the periodicity testing result of carrying out later on, judge that defect of pipeline is the tubing defective that can not grow or because anticorrosive coat destroys the developing fault that causes, thereby judge the speed of growth of corrosion, carry out the assessment of pipeline residual life.
At the pipeline pigging with detect in the work progress, carrying out the pigging work that deformation detection and corrosion must advanced line pipe roads before detecting, the purpose of pigging work is:
(1) removes the pipe interior residue as long-pending oil, dust, construction legacy etc., to reduce its influence to testing result.
(2) checking pipeline machinery trafficability characteristic can be to guarantee passing through smoothly of checkout equipment.
(3) according to wiper and go out the principle condition clearly and confirm tentatively whether pipeline possesses the condition of the detector that puts into operation.
The equipment that must use in the pipeline pigging work progress is exactly wiper, detection company wiper commonly used has the leather cup wiper at present, the gauging disc wiper, bristle pig, two straight two dish wipers wherein are a kind of leather cup wipers of using always, it is by two straight leather cups 1,2 and two dish leather cups 3 and pedestal constitute, the diameter of two straight leather cups all is the same with thickness, existing two straight two dish wipers are in the process of carrying out the pipeline pigging, if running into pipeline bigger undergauge or pipeline distortion occur and piles up under the situation of a large amount of foreign material the easy stifled phenomenon of card that takes place in wiper the place ahead.
Summary of the invention
Be to solve the deficiencies in the prior art, the object of the present invention is to provide a kind ofly when bigger undergauge or bigger distortion appear in pipeline, still can move on, do not block the pipeline cleaner of stifled phenomenon.
For achieving the above object, the technical solution adopted in the present invention is: a kind of pipeline cleaner, comprise two straight leather cups and two dish leather cups and pedestal, it is characterized in that: the diameter of the first straight leather cup is slightly less than the diameter of the second straight leather cup, the diameter of the second straight leather cup is less than or equal to the internal diameter of pipeline, while, the chamfering of certain angle was got in second straight leather cup edge, and had at least two apertures in straight leather cup excircle symmetry, and two dish leather cup diameters are bigger than the internal diameter of pipeline.
After having adopted the present invention, because two dish leather cup diameters are bigger than the internal diameter of pipeline, seal with the pipeline internal diameter, can make the front and back of wiper form certain pressure reduction, promote wiper operation forward in pipeline, the main effect of two straight leather cups is foreign material of releasing in the pipeline, it and pipeline blow-by, two straight leather cups are selected different diameters for use, the diameter of second straight leather cup is less than or equal to internal diameter of the pipeline, the diameter of the first straight leather cup is slightly less than the diameter of the second straight leather cup again, get the chamfering of certain angle again along the edge owing to second straight leather cup, and have at least two apertures in straight leather cup excircle symmetry, the ability of releasing foreign material in the wiper in-line running is reduced, and make wiper the place ahead be unlikely to pile up a large amount of foreign material, thereby strengthen the handling capacity of wiper, even if bigger undergauge or pipeline distortion appear in pipeline, can not block stifled phenomenon yet, guaranteed normally carrying out of pipeline pigging work.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the schematic diagram of the straight leather cup of wiper among the present invention.
The specific embodiment
Lift preferred embodiment below, and conjunction with figs. is as follows to the detailed description of the invention.
See Fig. 1, Fig. 2, carrying out two used straight two dish wipers of pigging with the pipeline of DN600 is example, the pipeline internal diameter of the pipeline of DN600 is 588mm, two dish leather cup 3 diameters are selected 596mm for use, the diameter of second straight leather cup 2 is selected 588mm for use, and the diameter of first straight leather cup 1 is selected 580mm for use, so just can guarantee first straight leather cup 1 easier passing through when undergauge appears in pipeline, the angle that chamfering is got at second straight leather cup 2 edge is 15 degree, each is separated by 90 ° and opens four apertures 4 on straight leather cup, and diameter is 30mm, and the ability of releasing foreign material in the wiper in-line running is reduced, and wiper the place ahead is unlikely to pile up a large amount of foreign material, the wiper maximum can be by the deflection of pipeline 30% like this, what strengthened wiper can cross ability, reduces the stifled risk of card takes place, and has guaranteed normally carrying out of pipeline pigging work.
