Feature:
For the structure of the triple-eccentricity seal butterfly valve, when the valve is under the complete open state, its butterfly plate sealing face will break away from the valve seat sealing face completely; when it is opened from 0 to 90°, the butterfly plate sealing face will break away from the valve seat sealing face upon opening; when it is closed from 90° to 0°, and only upon closing, the butterfly plate sealing face can contact and press onto the valve seat sealing face tightly.
