Description

Technical Field

[0002] After the installation of urban gas pipelines, in order to ensure the stable operation of the gas pipelines, it is necessary to promptly blow and clean the remaining impurities in the gas pipelines.

[0003] The current gas pipeline purging device is mainly composed of a high-pressure air pump and a single blowing nozzle installed at the air outlet of the high-pressure air pump. Although the above-mentioned purging structure can realize the purging and cleaning of impurities in the gas pipeline, there is only one blowing nozzle at the blowing port of the high-pressure air pump and the blowing position of the blowing nozzle is fixed. As a result, when purging impurities in the gas pipeline, the blowing nozzle is easily damaged, resulting in the device not blowing the gas pipeline smoothly. At the same time, since the blowing port on the gas pipeline purging device of the above-mentioned structure is in a fixed position, the purging force of impurities farther away in the gas pipeline is easily reduced due to the long gas pipeline, and the purging is not thorough.
