Mine electric butterfly, MD941X ore mine with an electric electric butterfly valve DN600: Ex-protection rating of IP68. Suitable for explosive environments, high safety factor, operating functions, stable performance. Explosion-proof products dI and dIIBT4 two kinds, dI for coal mining face non; dIIBT4 used in factories, for environmental IIA, IIB grade explosive gas mixtures T1 ~ T4 group was. Performance of this product comply with JB / T8528-1997 of. Explosion-proof performance in line with the provisions of GB3836.1-2000 and JB / T8529-1997 of. And explosion-proof electrical products by the National Testing Center test, made explosion-proof certification. Mine electric butterfly valve Features: 1, electric butterfly valve has a simple structure, small size, light weight, material consumption province, small installation size, switch quickly, 90 ° reciprocating rotary drive torque characteristics of small, used to cut, turn, adjusting the line of medium, having a good fluid sealing properties and closing control characteristics. 2, the electric valve can carry mud accumulation of fluid in the pipe mouth least. Under low pressure, can achieve a good seal. Regulation performance. 3, streamline design electric butterfly valve disc, so that the loss of fluid resistance, can be described as an energy-saving products. 4, electric butterfly valve stem through-rod structure, after quenching, with good mechanical properties and corrosion resistance, scratch resistance. Electric butterfly valve opening and closing the valve stem when only rotational movement without making lifting operation, the valve stem packing is not easy to destroy, reliable sealing. And disc taper pin fixed, extended end to prevent out design, in order to avoid the stem and disc connected to the stem of the accident when the collapse of the fracture. 5, electric butterfly valve connections are flanged, wafer, welded connections and lug wafer connection. Drive in the form of a manual, worm gear, electric, pneumatic, hydraulic, electro-hydraulic actuator linkage, enabling remote control and automation.
