The double eccentric butterfly valve is further improved on the basis of the single eccentric butterfly valve. Its structural feature is that the axis of the valve stem deviates from both the center of the butt erfly plate and the center of the body.The effect of double eccentricity enables the butterfly plate to quickly detach from the valve seat after the valve is opened, greatly eliminating unnecessary excessive compression and scraping between the butterfly plate andthe valve seat, reducing opening resistance, reducing wear, improving the valve seat life,and greatly reducing scraping. At the same time, it also allows the double eccentricitybutterfly valve to use metal seats, improving the application of butterfly valves in various fields.
The rubber ring needs to adopt a wedge-shaped structure tightly connected to the butterfly plate, and thesealing ring plays a crucial sealing role, and still maintains tightness after multiple opening and closing.
Huayi Rubber collaborated with SUFA Valve to develop the world's largest double eccentric butterfly valve,DN4800, which has been put into use and received high praise from customers.
