However, the existing pipeline valve structure is poorly designed. After the valve is switched in the pipeline, the user cannot accurately know whether the corresponding branch pipeline is in an open or closed state with the mainstream pipeline, or whether the valve is switched in place in the corresponding pipeline when switching, resulting in the branch pipeline that should be in a closed state still being connected to the mainstream pipeline, causing a waste of resources, poor practicality, and a small scope of application.
