Leak hunting equipment for detecting natural gas pipelines with different pipe diameters

Abstract

The invention relates to the technical field of natural gas pipeline detection and discloses leak hunting equipment for detecting natural gas pipelines with different pipe diameters. The equipment comprises a rack body, wherein the top of the rack body is fixedly connected with a disc body, the top of the disc body is fixedly connected with an air chamber, the top of the disc body is rotatably connected with a rotating wheel, a piston is movably connected in an air chamber, the end, far away from the disc body, of the air chamber is elastically connected with a suction port, and the top of the air chamber is elastically connected with an air outlet. The leak hunting equipment for detecting natural gas pipelines with different pipe diameters can detect leak of pipelines with different pipe diameters, such that the universality of the equipment is improved. Periphery gas of the pipeline is inhaled via a gas guiding pipe and the suction port by changing the volume of the air chamber and is discharged into a transparent container. After methane is reacted with oxygen in the transparent container, a yellow-green color deficiency becomes shallow quickly under illumination to generate an oily liquid which is easy to observe, thereby achieving an effect of lowering the detection cost as leak is detected by oxygen.

Description

technical field [0001] The invention relates to the technical field of natural gas pipeline detection equipment, in particular to a leak detection equipment for natural gas pipelines with different pipe diameters. Background technique [0002] With the development of science and technology, more and more resources are developed and utilized. Natural gas is one of them. Natural gas is flammable. Once a gas pipeline leaks, it is very dangerous. It may explode when encountering an open flame. Therefore The tightness detection of pipelines is very important. The existing natural gas pipeline detection equipment can only detect the leakage of one pipe diameter. For natural gas pipelines with different diameters, different specifications of detection equipment are required, which increases the cost of detection, and the detection process Due to different leak detection principles, there are many types of leak detectors used, such as gas sensors, infrared laser detection equipment,...
