Double eccentric soft sealing flange butterfly valve outlet Uzbekistan

The nominal diameter of double eccentric butterfly valves can be dn100-dn2600, and the engineering pressure can be pn10-pn16. The valve body of this batch of double eccentric butterfly valves is nodular cast iron, and the valve plate is also nodular cast iron. The pressure is PN10, and the size is mainly dn400. The double eccentric structure is adopted, which has longer service life than the center line butterfly valve. The two-stage valve stem design increases the flow area and reduces the flow resistance. A labor-saving device is designed at the bottom of the valve stem to reduce the operating torque.

The double eccentric butterfly valve is further improved on the basis of the single eccentric butterfly valve. The utility model is characterized in that the axis of the valve rod deviates from the center of the butterfly plate and the center of the body. The effect of double eccentricity enables the butterfly plate to leave the valve seat immediately after the valve is opened, greatly eliminates the unnecessary excessive extrusion and scraping between the butterfly plate and the valve seat, reduces the opening resistance, reduces the wear and improves the service life of the valve seat. At the same time, the double eccentric butterfly valve can also adopt metal seat, which improves the application of butterfly valve in high temperature field, mainly serving the fields of petroleum, metallurgy, water treatment, water supply and drainage, etc.
