BUTTERFLY VALVE WITH ANTI-SCALE SYSTEM

摘要

A butterfly valve with an anti-scale system is provided to extend the cycle of scale removal work by delaying accumulation time of scales in the butterfly valve. A butterfly valve with an anti-scale system for delaying scale accumulation time includes a disc, a housing, and a brush. The disc is disposed in the housing. The brush having a specific pattern is interposed between the housing and the disc, spaced from the disc. The disc is curved to increase the contact area with the brush.
