Abstract
The invention discloses a flange. 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 outside to inside. The middle through hole is a step hole, so that a step part is formed. A plurality of threaded blind holes are formed in the step part. A filter screen is arranged on the step part and fixed to the step part through a plurality of bolts which are matched with the threaded blind holes. The sealing area is provided with a combined type sealing gasket. The combined type sealing gasket comprises a first copper gasket layer, a second copper gasket layer and a fabric layer arranged between the first copper gasket layer and the second copper gasket layer. The first copper gasket layer and the fabric layer are bonded through an adhesive, and the fabric layer and the second copper gasket layer are bonded through an adhesive. In this way, the flange has a good filtering function and an excellent sealing effect, and is high in practicability.
