The invention discloses a pipeline leakage detection device. The device comprises at least two flow meters, a controller and an alarm device, wherein at least two flow meters are arranged at differentpositions along the axial direction of a pipeline, and are used for correspondingly acquiring flow values of the pipeline and sending the flow values to the controller; the controller is used for acquiring the flow values and analyzing the flow values according to a preset control rule to generate and transmit corresponding control signals; and the alarm device is used for receiving the control signals and sending corresponding warning information according to the control signals. According to the device and a method, whether the pipeline leaks or not can be directly obtained, and the detection mode is simple and accurate. The invention further discloses the pipeline leakage detection method which has the beneficial effects mentioned above.
Description
technical field [0001] The invention relates to the field of device detection, in particular to a detection device and method for pipeline leakage. Background technique [0002] In recent years, more and more vehicles use natural gas as fuel, and there are more and more natural gas leakage accidents in vehicles. Natural gas is a flammable gas, its leakage will cause air pollution, and natural gas may cause combustion or explosion accidents when exposed to open flames, resulting in serious consequences. [0003] In order to be able to understand the leakage of natural gas in time, the existing technology places at least one gas concentration sensor in the engine compartment core of the natural gas vehicle and the trunk of the natural gas tank respectively, and detects the concentration of natural gas through the gas concentration sensor and transmits the detection value to the controller. The controller analyzes the detection value according to the preset control rules, gene...
