A leak detection and repair device for municipal natural gas pipelines

Abstract

The invention discloses a leak detection and repairing device for municipal natural gas pipelines. The switch and the safety switch are set on the outer layer of the base and embedded in the base. The composite translation side columns are movably installed at the left and right ends of the base and are movably connected with the tension frame. The connection with the follower plate controls the follower plate to move up and down, and is driven by a small motor. With the cooperation of the tension spring, the opening of the upper tension rod and the lower tension rod is limited, so that the pipeline can be positioned as a leak detector. It can detect different positions of the pipeline, which increases the detection range. The fixed-point leak detection is realized by the measuring port. The measuring rod measures the position of the leak detection. According to the measurement results, the pipeline patcher is controlled to expand and contract up and down and the pipeline is repaired to achieve precise fixed-point. repair.

Description

technical field [0001] The invention relates to a leak detection and repairing device for municipal natural gas pipelines, which belongs to the technical field of leak detection and repairs for natural gas pipelines. Background technique [0002] Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere. The definition of "natural gas" that people have used for a long time is a narrow definition from the perspective of energy, which refers to the mixture of hydrocarbon and non-hydrocarbon gases naturally stored in the formation. In petroleum geology, it usually refers to oil field gas and gas field gas. Its composition is dominated by hydrocarbons and contains non-hydrocarbon gases. [0003] Pipelines that transport natural gas from mining sites or processing plants to urban gas distribution centers or industrial enterprise users are also called gas pipelines. The use...
