Medium sensitivity of butterfly valve

The butterfly valve is suitable for the pipeline system that transports water, oil, gas, water-solid two-phase and gas-solid two-phase flow as a switch or adjustment device. Therefore, the sensitivity of the butterfly valve sealing pair to the medium also needs to be considered when designing One of the important factors, the design is mainly considered from the material selection and structural form. For example, for a cut-off butterfly valve with a high dust content in the medium, it is necessary to use a rubber material with good elasticity as a sealing ring, or use a multi-layer metal hard sealing ring with a self-cleaning structure, and rely on the sealing pair to seal the body while the sealing pair is relatively moving. It can remove dirt such as particles, or use blowing and cleaning functions to reduce the pollution of dust on the sealing pair.
