The present invention is applicable to the technical field of pipeline detection, and provides an external pressure detection device for pipelines, including a casing, a fixing device, a detection device and a support device, the fixing device includes a fixing part and a sealing part, and the detection device includes a pressure gauge and a pressure relief valve and a supercharging device; the support device includes a symmetrically arranged support rod, a support frame, a driving rod, a driven rod and a power part, the support rod is bent and formed, one side of the active rod is fixedly connected to the power part, and the driven rod includes an upper driven rod Rod and lower driven rod, the upper and lower ends of the limit block are respectively movably connected to the end of the upper driven rod and the end of the lower driven rod, and the other end of the lower driven rod is movably connected to the bottom of the bent end of the support rod. Fixing sleeve that accommodates the support rod; the support device is located below the sleeve. Thereby, the invention can improve the detection quality of pipeline airtightness, and at the same time, can facilitate movement, effectively detect pipelines in different positions, and improve work efficiency.
Description
technical field [0001] The invention relates to the technical field of pipeline detection, in particular to a pipeline external pressure detection device. Background technique [0002] At present, the pipe end welding, weld seam and socket joint of the pipeline, especially the leakage water pressure detection of the large-diameter pipeline, is mainly carried out by the internal pressure method, and the pressure equipment for detecting the large-diameter pipeline is huge and inconvenient to move, which is called the large-diameter pipeline. The pipeline pressure detection on the pipeline construction site brings inconvenience. When the local pressure index and leakage of large-diameter pipelines are in dispute, it is difficult to test the existing equipment. [0003] In summary, there are obviously inconveniences and defects in the actual use of the prior art, so it is necessary to improve it. Contents of the invention [0004] In view of the above-mentioned defects, the ...
