What is the concept of corner filter? The angle filter is suitable for various water supply systems, especially the continuous operation without shutdown system, which can filter out various mechanical impurities in the water and ensure the safe and reliable operation of the system equipment.Example of corner filter marking:1. Nominal diameter 100 and nominal pressure 1. 6MPa. the filter screen specification is 80 mesh/inch, and the angle-through pipe filter made of carbon steel is marked as jsy I 100-1.6/80C.2. the nominal size is 250, the nominal pressure is 2. 5MPa, the filter screen specification is 60 mesh/inch, and the angle inclined pipe filter made of stainless steel is marked as: JSJ250-2.5/60 S.3. the nominal size is 80, the nominal pressure is 4.0MPa, the filter screen specification is 30 Mesh/inch, and the straight-through basket filter made of stainless steel is marked as jsl I 80-4.5/30 S.Angle filter structure and principle:The inner structure of the angle filter is a pig man
