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.

Description

technical field [0001] The invention relates to the technical field of flanges, in particular to a flange. Background technique [0002] Flange is a connection tool, and flange connection refers to a detachable connection in which flanges, gaskets and bolts are connected to each other as a combined sealing structure. Flanges are divided into threaded (screw connection) flanges, welding flanges and clip flanges. Flange connection is widely used in construction industry, urban water supply, boiler pressure vessel, petroleum industry, gas supply, chemical industry, food industry, Fire protection, pharmaceutical industry, power station, water conservancy, HVAC and other industries. Existing flanges do not have filtering capabilities and cannot adequately meet industry requirements. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a flange with better filtering function and better sealing effect, and strong pra...
