Description
Technical Field
[0001] The utility model relates to the technical field of steam pipelines, in particular to a ground drainage device for directly buried steam pipelines. Background Art
[0002] Condensate will be generated during the steam pipeline transportation process. If the condensate is not discharged in time, water hammer will occur and cause damage to the pipeline. Therefore, a drain device should be installed at a low point along the steam pipeline. When the steam pipeline is directly buried, an underground drain well is generally set up. Because the underground drain well occupies a large area, there is no place to set it up locally, and the drain well is set up underground, which is not conducive to inspection, inspection and maintenance.
