[0002] In the existing pipeline system, a filter is connected in parallel with a bypass pipe to supply water to the user end. When the pipeline filter in the system fails, the bypass valve of the pipeline filter is opened to supply water to the system, and the inlet and outlet valves of the filter are closed at the same time, and the filter is shut down for maintenance. Since the turbid loop system is an open system, there are debris in the water supply process that flows to the user end through the bypass pipe and blocks the nozzle at the user end, affecting the user's normal production. In severe cases, the rolling mill needs to be stopped for treatment. The main reason for the technical disadvantage is that there is no filtering device on the bypass pipe.

[0003] The Y-type filter currently available on the market can filter the bypass pipe. However, the Y-type filter is relatively expensive and it is troublesome to replace the Y-type filter. It is necessary to cut off the pipe and reinstall the Y-type filter. It is also necessary to find a Y-type filter with a suitable pipe diameter, otherwise it is difficult to replace.
