The electric flanged butterfly valve is composed of valve body, butterfly plate, sealing ring, transmission mechanism and other main components. Its structure adopts three-dimensional eccentric principle design, elastic seal and hard and soft multi-layer seal compatible processing technology, so that the butterfly valve in operation, reduce its torque force, to achieve labor saving, energy saving functions. Thus ensuring overall corrosion resistance. High temperature resistance. , the reliability of anti-degradation. Based on the introduction of foreign advanced technology, this product adopts precision J-shaped elastic sealing ring and three-eccentric multi-layer metal hard seal structure, which is widely used in the medium temperature ≤425℃ gold, electric power, petrochemical industry, water supply and drainage and municipal construction and other industrial pipelines for regulating flow and carrying current body.
The valve adopts three eccentric structure, the valve seat and plate sealing surface are made of different hardness and stainless steel, with good corrosion resistance, long service life, the valve military seal function, the product conforms to the ***GB/T13927-92 valve pressure test standard. The valve adopts three eccentric sealing structure, the valve seat and the butterfly plate almost no wear, with more and more tight sealing function; The sealing ring is made of stainless steel, with the double advantages of metal hard seal and elastic seal, regardless of low temperature and high temperature, it has excellent sealing performance, corrosion resistance, long service life and other characteristics; The sealing surface of the plate is surfacing cobalt-based cemented carbide, which is wear-resistant and has long service life. The large size plate adopts quilted frame structure, high strength, large flow area and small flow resistance; The valve has a bidirectional sealing function, the installation is not limited by the flow direction of the medium, nor affected by the spatial position, can be installed in any direction; The drive unit can be installed in multiple stations (90° or 180° rotation) for easy user use.
Main performance characteristics
Small and light, flexible operation, labor-saving, convenient;
Reliable sealing, can achieve gas seal without leakage;
The three-eccentric principle is adopted to make the sealing surface approximate zero loss and extend the service life of the valve.
Wide range of applications. Such as: can be used for water, steam, oil, air, gas and other media.
Applicable to different temperatures and pressure levels below 6.4MPa, corrosion resistance and other medium pipelines
