The equipment with water-cooled star-shaped ash discharge valve has been standardized. The ash discharge valve processed by the working end face and side clearance can discharge ash smoothly and overcome large negative pressure. The casing of the equipment is made of high-quality heat-resistant cast iron, the rotor (that is, the central shaft part) blades are made of 304 material, the central shaft is designed as a hollow shaft, and the material is steel 45 and has been quenched and tempered. The hollow shaft should be supplied with cooling water during operation. , In order to overcome the influence of high-temperature materials on the deformation of the spindle, the equipped motor and reducer of the equipment are all selected domestic famous products. Standard and reasonable design, materials and production can ensure the long-period trouble-free operation of the star-shaped ash discharge valve equipment.
