Natural gas pipeline leakage detection method

Abstract

The invention belongs to the technical field of natural gas pipeline equipment, in particular to a natural gas pipeline leakage detection method. By remotely controlling a natural gas pipeline leakagedetection device, the situation that operators have no way to evacuate in time when a safety accident occurs can be prevented, whether a pipeline leaks or not can be detected according to the sound made by an alarm, meanwhile, a specific leakage point can be detected out, and later repairing and replacement are convenient. The applied natural gas pipeline leakage detection device comprises a frame and a controller; a first sliding plate and a second sliding plate are both of round design and are slidably connected to the inner walls of the frame, and the first sliding plate is located below the second sliding plate; and a spring is fixedly connected between the lower surface of the first sliding plate and a motor rotary shaft. The natural gas pipeline leakage detection method is easy andconvenient to implement, long in detection distance and suitable for narrow space where people cannot reach and pipelines with too high heights, and the specific leakage point can be detected while the personal safety of the operators can be ensured.

Description

technical field [0001] The invention belongs to the technical field of natural gas pipeline equipment, in particular to a natural gas pipeline leakage detection method. Background technique [0002] Natural gas pipeline refers to the pipeline that transports natural gas, including associated gas produced in oil fields, from mining sites or processing plants to urban gas distribution centers or industrial enterprise users, also known as gas pipelines. With the continuous improvement of people's living standards, natural gas The use has also entered every household, and there are more and more natural gas pipelines that need to be installed. [0003] There are also some technical solutions for natural gas pipeline leakage detection devices in the prior art. For example, a Chinese patent with application number 2017216119715 discloses a natural gas pipeline leakage detection device, which includes a shell, and the bottom of the inner wall of the shell is opened with a The firs...
