Embodiment

[0029] A gas pipeline leak detection device, combined with Figure 1-Figure 2 , including two detectors 3 and several curved bridges 14 . The curved bridge 14 is detachably arranged on the flange 2, and the curved bridge 14 is provided with a road groove 15. The specific detachable method can be clamped or bolted, and the detachable method is very mature so it will not be repeated. The detector 3 includes a housing 8, several first driving machines, a second driving machine 10, a detection unit and an adjustment unit. There are two detectors 3, and they are respectively located directly above and directly below the gas pipeline 1. The casing 8 of the detector 3 is horizontally fixed with a first connection frame 5, and the first connection frame 5 is vertically fixed with a second connection frame. Connecting frame 6, the opposite ends of two second connecting frames 6 are hollow, and the hollow parts of two second connecting frames 6 adjacent up and down are slidingly provid...

Abstract

The invention relates to the field of gas pipeline engineering, and specifically discloses a gas pipeline leak detection device, which includes a detector. The detector includes a casing, a plurality of first driving machines, a second driving machine and a detection unit. A driving wheel, the second driving machine is provided with a second driving wheel, the second driving machine is located between several first driving machines, the diameter of the first driving wheel is larger than the second driving wheel, and the outer circumference of the first driving wheel is Serrated; the detection unit includes a detection box and a number of pressure sensors. The detection box is arranged at the bottom of the shell. An elastic sheet is arranged on the top, and the pressure sensor is arranged in the detection box, and the pressure sensor is in contact with the elastic sheet to detect the pressure exerted by the elastic sheet; the flange of the gas pipeline is provided with a curved bridge. The purpose of the invention is to solve the technical problem of how to quickly detect the leak point of the gas transmission pipeline.

Description

technical field [0001] The invention relates to the field of gas transmission pipeline engineering, and specifically discloses a gas transmission pipeline leakage detection device. Background technique [0002] Gas transmission pipeline is a long transportation pipeline specially used to transport natural gas medium. The total length of gas transmission and gas pipelines in my country is more than 100,000 kilometers. Gas pipelines are one of the lifeline projects of cities and even the whole country. However, accidents of gas pipelines occur frequently across the country. The causes of accidents are generally aging leakage, external force damage, geological disaster damage, etc., which lead to gas leakage and then fire, explosion and other hazards. . Therefore, it is necessary to conduct leak detection on gas pipelines every year to facilitate timely maintenance and replacement. The existing detection equipment is generally a hand-held combustible gas detector, which is cum...
