Electric butterfly pneumatic valve structure features and technical parameters for desulphurization

electric desulphurization butterfly pneumatic valve designed for power plant desulfurization and denitration project design, fully consider the desulfurization serous corrosion and wear of pneumatic valve, pneumatic valve plate lining is the only guarantee access to serous parts, other parts don't be limestone ( Or lime paste) Slurry erosion. Therefore, pneumatic valve and pneumatic valve stem don't need to use expensive alloy ( Materials, thus greatly save the cost. Desulfurization butterfly pneumatic valve unique pneumatic valve seat design completely separates pneumatic valve body and fluid, compared with other similar pneumatic valve, it has a better way of pneumatic valve seat firmly, in-place replacement pneumatic seat quickly, pneumatic valve in zero leakage, and less friction. Pneumatic valve pneumatic butterfly valve plate with high-performance alloy ( Material, effectively resist slurry corrosion and wear.
electric butterfly pneumatic valve is introduced for desulphurization
electric desulphurization control pneumatic valve main structure by the pneumatic valve, pneumatic valve, pneumatic valve seat, pneumatic valve stem and transmission operators such as components, pneumatic valve seat adopts detachable structure, and can according to the physical and chemical properties of different medium, choose the corresponding high temperature resistant, good low temperature resistance, corrosion resistance, light resistance, ageing resistance material.
electric desulfurization no eccentric butterfly pneumatic valve adopts the structure of linear design, has significant low operating torque characteristics of the electric device when the economy significantly; Using rubber lining structure, the butterfly plate circle sealing surface precision machining to a higher degree of finish, low coefficient of friction of rubber pneumatic valve seat, pneumatic valve life is long; Pneumatic valve plate seal face flow characteristics of a linear state, has small flow resistance coefficient, pneumatic valve flow resistance is small; The unique design of the moulded rubber pneumatic seat has excellent balance and supportive, effectively avoid uneven caused damage to the rubber, pneumatic valve seated position, the rubber is in the best state of compression to keep zero leakage.
pneumatic valve nodular cast iron shell inside and outside surface can be used high temperature electrostatic spraying epoxy resin powder coating, the coating has high corrosion resistance, high bonding strength and ductile cast iron matrix, for coating. — 。 mm。
to done, ZTHQ series electric actuators, ACV or ACV power switch control can be carried out on listed listed. Without the other match servo amplifier, input, - MADC or - ADC) Signal, the implementation of the adjustment of the parameters such as pressure, flow rate and temperature.
