Problems solved by technology

[0002] The traditional butterfly valve lagging on the market is used in various fields of production and life. If it encounters strong acid and alkali in harsh environments, it will destroy the functional characteristics of the rubber ring itself and affect the normal production and life. Therefore, for this type of Butterfly valve lagging in the environment has certain requirements for oil resistance, heat resistance, and acid resistance, but the butterfly valve lagging on the market now often fails to meet the requirements, which is not conducive to production and life.
