AI Technical Summary
Existing butterfly valves have complex structures, their sealing rings are prone to wear, their service life is short, they do not have bidirectional sealing capabilities, their installation direction is restricted, and there is a risk of media leakage.
The butterfly valve adopts a U-ring elastic seal, combined with a guide mechanism and a fully welded design. It uses a U-shaped metal valve seat seal ring, and reduces wear through the guide bushing and V-shaped elastic metal ring to ensure reliable sealing. The anti-rotation pin connection ensures accurate opening and closing.
It improves sealing performance, extends service life, adapts to high temperature and high pressure environments, eliminates the risk of media leakage, and ensures accurate switching action.
