Embodiment 1

[0027] The pressure gas pipeline leakage detection system includes a hub 1, 6 spoke fingers 2, 6 sensing units 3, a positioning unit 4, 6 fingers 5 and a console.

[0028] The core 1 moves in the pipeline with the pressure gas. The center 1 is equipped with fluid dynamics software CFD, and according to the pressure data collected by the sensing unit 3, the pressure gradient distribution data inside the pressure gas pipeline is automatically generated, and according to the preset pressure gradient change critical value, it is confirmed whether the gas pressure pipeline is Leakage, in the event of a confirmed pipeline leak, an alert is sent to the console.

[0029] One end of the spoke fingers 2 is fixedly connected to the central hub 1 for moving the central hub 1 in the pipeline with the pressure gas, and the six spoke fingers 2 are symmetrically distributed around the center of the central hub 1 .

[0030] Each of the sensing units 3 is installed on one of the spoke fingers ...

Embodiment 2

[0035] Compared with the second embodiment, this embodiment has the same technical features except for the following differences.

[0036] The hub 1 is used to analyze and process the data collected by the sensing unit 3 to form real-time pressure data, and transmit the pressure data to the console.

[0037] The console is equipped with fluid dynamics software CFD, which generates a pressure gradient distribution map inside the pressure gas pipeline according to the pressure data transmitted by the center 1, and determines whether the pipeline leaks according to the preset pressure gradient change critical value.

Abstract

A leak detection system for a pressure gas pipeline, including a hub, several spokes, a number of sensing units, and a console; wherein, the hub moves in the pipeline with the pressure gas, and is used to analyze and process the data collected by the sensing units to form real-time pressure data or pressure Gradient data, and the pressure data or the alarm signal obtained by analysis and processing are transmitted to the console; one end of the radial finger is fixedly connected with the central core (1), which is used to make the central core move with the pressure gas in the pipeline, and several radial fingers are distributed symmetrically with the central center ;The sensing unit is installed on the spoke finger to sense the pressure value of the pressure gas in the pipeline and transmit the collected data to the center; the console and the center are connected by wireless or wired to receive the signal transmitted by the center and analyze and process and send out instruction. The invention can more accurately judge whether there is leakage in the pressure gas pipeline.

Description

technical field [0001] The invention relates to a pressure gas pipeline leakage detection system and method. Background technique [0002] During the pipeline transportation of pressurized gas, due to the existence of various influencing factors, the pipeline often leaks. Pipeline leaks not only cause resource loss, but also cause serious safety hazards. Therefore, it is very important to carry out leak detection on the pressure gas pipeline. But at present, it is generally only based on the change of gas pressure to judge whether the pipeline is leaking. This kind of judgment method not only cannot accurately judge the leakage of the pipeline, but also cannot accurately locate the location of the leakage. [0003] To sum up, there is currently no system and method that can accurately detect whether the pressure gas pipeline is leaking and accurately locate the leak point. Contents of the invention [0004] In order to solve the technical problems of poor detection accu...
