Abstract
The invention discloses a flange with a filtering function. The flange comprises a flange plate body. The flange plate body is sequentially divided into a bolt fastening area, a sealing area and a middle through hole from exterior to interior. The middle through hole is a step hole, and accordingly a step part is formed. The step part is provided with a plurality of threaded blind holes and provided with a filtering net. The filtering net is fixed to the step part through a plurality of bolts matched with the thread blind holes. By means of the above manner, the flange is simple and reasonable in structure, the filtering function is achieved, and the industry requirement can be fully met.
