Thread-based under-pressure oil pipe leakage repairing device

Abstract

The invention discloses a thread-based under-pressure oil pipe leakage repairing device, and relates to the technical field of pressure pipeline protection devices. The thread-based under-pressure oil pipe leakage repairing device comprises a compression bolt, a lock washer, an end cover, a rotating hand wheel, a main rotating rod, a rear pressing plate bolt, a rear pressing plate, a cavity, a push sleeve, a leakage-proof partition plate sleeve, a transmission gear shaft, a push cover, a front pressing plate, a control gear shaft, a flange buckle, a rubber hole film and the like. When leakage repairing is carried out, a leakage repairing flange and the rubber hole film wrap a leakage point, the rotating hand wheel is rotated, a main transmission rod drives the push sleeve to push a leakage repairing agent in the cavity forwards, the leakage repairing agent is evenly distributed in the rubber hole film, the leakage repairing agent overflows from small holes of the rubber hole film and is in full contact with the leakage point, and then an injection needle on the rubber hole film is pulled out to complete leakage repairing; and emergency leakage repairing can be conducted on the oil pipe under the condition of medium-low pressure pipeline leakage, and the device has the characteristics of being wide in applicability, high in leakage repairing efficiency, easy to operate and the like.

Description

technical field [0001] The invention relates to a thread-based pressure oil pipe leakage repair device, in particular to a pressure oil pipe leakage repair device capable of resisting pressure and impact in the case of medium and low pressure oil pipe leakage. Background technique [0002] Pipeline leakage will not only cause a lot of waste of resources, but also cause serious damage to the natural environment. At present, pipeline leakage repair technology is in the development stage. Most leak traps need to stop the well, stop the pressure, and release the pressure before the empty pipe can be manually operated. Repair, such as Patent Publication No. CN211118265U, although the reliability of the leakage repair device is better, the oil pipe can only be repaired after the empty pipe is needed, the scope of application is small, and it belongs to the consumption type repair device, the cost is high, and it cannot be reused; the present invention The head adopts screw drive, ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of this invention is to solve the problems of oil and gas pipeline pressure leak repairing tools in the current market, which are bulky, difficult to operate, and low leak repairing effect.

When repairing the leaks of the pipelines, it is necessary to completely wrap the pipelines before the leaks can be repaired. The staff not only has cumbersome operations when repairing leaks, but also has problems such as low efficiency of repairing leaks.
