Rectangularsingle-blade valve is a reliable equipment for regulating and opening air, fluegas, dust gas and combustible gas. It can be used as ventilation equipment for ventilation and dust removal pipeline. Electric rectangular louver valve is easy to operate, especially suitable for large caliber, large flow rate, low pressure difference occasions, widely used in metallurgy, mining, building materials, chemical industry, power station and other industrial departments.
Desulphurization valve is a kind of valve which is suitable for desulphurization and denitrification in power plant. Limestone-gypsum wet method is used in desulphurization system.The medium of limestone slurry system will appear strong corrosion after desulphurization. The requirement of desulphurization valve is that it cannotonly resist chloride, oxide, acid, but also withstand harsh particle wear and slurry scour. Special valves for desulphurization can be divided into manual,electric and pneumatic in terms of execution mode.
The structure of the valve for the rectangular desulfurization is as follows: the structure of the desulfurization valve is reasonable, the operating torque islow, the appearance of the configuration executor is small, the valve plate1.4529 or 1.4469 has high strength and corrosion resistance, and the valve seat of the desulfurization valve has extremely strong chloride and acid-oxygen corrosion, is resistant to erosion and has long service life, the balance and the support property of the molded rubber valve seat are effectively avoided,the damage to the rubber due to uneven stress is effectively avoided, and when the full-closed position of the desulfurization butterfly valve is in the fullyclosed position, the rubber is in an optimal compression state to keep zero leakage
The automatic control valve is equipped with high quality electric actuator or single and double acting pneumatic actuator, with clutch to realize hand,electric dual use, rubber sealing surface at both ends of desulphurization valve protruding nodular cast iron flange surface, valve without additional rubber sealing gasket when pipe installation. The inner and outer surface of nodular cast iron shell of rectangular desulphurization valve is coated with epoxy resin powder sprayed at high temperature. The coating has high corrosion resistance and very high bonding strength with nodular cast iron substrate.
