STEELFlange type hard sealed butterfly valve
The valve body and valve seat of a three eccentric metal hard sealed butterfly valve are connected components, and the sealing surface of the valve seat is welded with heat-resistant and corrosion-resistant alloy materials. The multi-layer soft stacked sealing ring is fixed on the valve plate. Compared with traditional butterfly valves, this type of butterfly valve has the advantages of high temperature resistance, easy operation, no friction when opening and closing, and compensating for sealing with the increase of torque of the transmission mechanism when closing, improving the sealing performance and extending the service life of the butterfly valve. It is suitable for industries such as high temperature resistance, high pressure resistance, corrosion resistance, and wear resistance. The structural types can be divided into single eccentricity, double eccentricity, and triple eccentricity.
Structural characteristics
1. Novel and reasonable design, unique structure, light weight, convenient operation, and fast opening and closing;
2. Hard sealed telescopic butterfly valves not only have the function of regulating and intercepting flow, compensating for thermal expansion and contraction caused by pipeline temperature differences, but also provide convenience for valve installation, replacement, and maintenance;
3. The sealing part can be adjusted and replaced, and the sealing performance is reliable
