Description

Technical Field

[0001] The utility model relates to the technical field of filter devices, and more specifically, to a filter device for water supply and drainage. Background Art

[0002] When municipal water supply and drainage pipelines are transporting water, the water may contain impurities, which may easily cause blockage in the main pipeline, affecting the water transport of the pipeline. In addition, there are several branch pipelines connected to the main pipeline. If only a single filtration is performed through the main pipeline, the filtration effect is poor, and some impurities will still enter the branch pipeline. When the connection section between one of the branch pipelines and the main pipeline is blocked, the main pipeline needs to be closed to stop transporting water, and then the connection section between the branch pipeline and the main pipeline needs to be disassembled for unblocking or replacement. At this time, the remaining branch pipelines cannot use the water source, which is very inconvenient. Utility Model Content
