Leakage detection device for natural gas hydrogen-doped pipeline

Abstract

The invention discloses a leakage detection device for a natural gas hydrogen-doped pipeline, which belongs to the field of natural gas hydrogen-doped pipelines and comprises a first detection main body, a second detection main body and a cushion layer, fixing devices are symmetrically arranged on the two sides of the first detection main body, and fixing rings are symmetrically arranged on the two sides of the second detection main body; a first baffle plate is arranged at the right position of the middle in the first detection main body; a detection pipe extending into the first detection body is arranged in the middle of the surface of the first detection body, and a detection meter is connected to the top of the detection pipe. According to the invention, through the cooperation of the slot, the projection and the sealing plate, the sealing performance of the detection device during gas leakage detection is further improved, and the detection result is accurate and rapid. By improving the fixing device, the practical use is more convenient. By improving the baffle plate in the first detection main body, the flange plate on the pipeline can be located at the middle position of the detection device in the detection process, so that the detection pipe and the detection head are located right above the flange plate, and the detection speed is higher.
