Abstract
The utility model relates to a hydraulic pipeline leaking stopping device which comprises a box body, a hydraulic arm II, a hydraulic arm I, a leaking stopping piece, a pipeline, tightening steel rings, a hydraulic cylinder and hydraulic pipes. The leaking stopping device is characterized in that the hydraulic cylinder is fixed on the box body through the two hydraulic pipes; the box body is fixed on the pipeline through the tightening steel rings; and the leaking stopping piece is fixed on the hydraulic arm I. The utility model has the benefits as follows: repair personnel are far from a leakage point, so that the repair risk is reduced; the hydraulic cylinder can be operated for repair at a place 10 m away; through the adoption of hydraulic pressure serving as power, the leaking stopping piece can be tightly fixed at the leakage point; the mode of pressure release is not adopted, so that manpower, time, and oil and gas resources are all saved; and the leaking stopping device is safe and reliable and has simple structure.
Description
Technical field
The utility model relates to oil and gas pipes system repairing field, specifically a kind of hydraulic pipeline leak stopping device.
Background technique
At present, increasing along with the long oil and gas pipeline of China, oil and gas pipes is revealed to pipeline transport enterprise and has been brought great risk, when pressure sealing device in the past has leak source on long oil and gas pipeline, can simply rush to repair leak source, but need the pipeline brownout operation during repairing, and the repairing personnel risk is also bigger.
Summary of the invention
The purpose of this utility model provides a kind of hydraulic pipeline leak stopping device, the technological scheme that its technical problem that solves the utility model adopts is: structure of the present utility model comprises casing, No. two hydraulic arms, a hydraulic arm, sealing piece, pipeline, fastening steel ring, oil hydraulic cylinder, hydraulic tube, it is characterized in that oil hydraulic cylinder is fixed on the casing by two hydraulic tubes, casing is fixed on the pipeline by fastening steel ring, sealing piece is fixed on hydraulic arm, by No. two hydraulic arms, the motion of a hydraulic arm is fixed on the pipeline leak point sealing piece, after compressing, sealing piece and pipeline weld repairing, overall pulling down leak stopping machine after the end of job; Because about the power that No. two hydraulic arms, hydraulic arm provide by hydraulic press makes it to have, the characteristics of side-to-side movement, the repairing personnel are operated away from leakage point, also just promptly avoided the step-down repairing, reduced personnel's injury risk, the power that oil hydraulic cylinder provides can be in pipeline carries out normal shutoff under 30 kilograms the pressure.
The working principle that realizes the hydraulic pipeline leak stopping is, when leak source appears in oil and gas pipeline, earlier the leak stopping machine is fixed on pipeline one side by fastening steel ring apart from leakage point≤30cm, by hydraulic power No. two hydraulic arms are moved to directly over the leak source, make oil hydraulic cylinder drive sealing piece then and press on the leak source, not leaking outside with oil (gas) is as the criterion.When confirming that oil (gas) nothing leaks outside, sealing piece is welded on the pipeline.
The beneficial effects of the utility model are, this hydraulic pipeline leak stopping device can allow the repairing personnel away from leak source, reduce the repairing risk, the operation oil hydraulic cylinder just can be rushed to repair outside 10 meters, adopts hydraulic pressure as power, can make sealing piece tightly be fixed on the leak source, need not take the step-down mode, promptly save manpower, time, save petroleum resources again, safe and reliable, simple in structure.
Description of drawings
Fig. 1 is the utility model example structure schematic representation;
Among the figure: casing 1, No. two hydraulic arms 2, hydraulic arm 3, sealing piece 4, pipeline 5, fastening steel ring 6, oil hydraulic cylinder 7, hydraulic tube 8.
Embodiment
With reference to accompanying drawing the utility model is done following concrete detailed description, structure of the present utility model comprises casing 1, No. two hydraulic arms 2, a hydraulic arm 3, sealing piece 4, pipeline 5, fastening steel ring 6, oil hydraulic cylinder 7, hydraulic tube 8, it is characterized in that oil hydraulic cylinder 7 is fixed on the casing 1 by two hydraulic tubes 8, casing 1 is fixed on the pipeline 5 by fastening steel ring 6, sealing piece 4 is fixed on hydraulic arm 3, by No. two hydraulic arms 2, the motion of a hydraulic arm 3 is fixed on pipeline 5 leak points sealing piece 4, sealing piece 4 welds repairing, overall pulling down leak stopping machine after the end of job after compressing with pipeline 5; Because about No. two hydraulic arms 2, the power that No. one hydraulic arm 3 provides by hydraulic press make it to have, the characteristics of side-to-side movement, the repairing personnel are operated away from leakage point, also just promptly avoided the step-down repairing, reduced personnel's injury risk, the power that oil hydraulic cylinder provides can be in pipeline carries out normal shutoff under 30 kilograms the pressure.
The working principle that realizes the hydraulic pipeline leak stopping is, when leak source appears in oil and gas pipeline, earlier the leak stopping machine is fixed on pipeline one side by fastening steel ring 6 apart from leakage point≤30cm, by hydraulic power No. two hydraulic arms 2 are moved to directly over the leak source, make oil hydraulic cylinder 7 drive sealing piece 4 then and press on the leak source, not leaking outside with oil (gas) is as the criterion.When confirming that oil (gas) nothing leaks outside, sealing piece 4 is welded on the pipeline 5.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design concept; common engineers and technicians make the technical solution of the utility model in related domain various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
