Vertical slurry quick opening round blind, quick opening round pulp horizontal blind, the company produced LSM type wheel paddle fast - opening (patent number: ZL03210870.2), using a coaxial two-piece blind plates, which is characterized by is axially stationary front blind, through the use of screw drive behind the wheel paddle card board beveled axial thrust forward rotation, push the front blind translational extrusion seals, blinds closed and locked aim to achieve . Thus ensuring the blind with no relative motion between the seal to avoid the blind plate and seal friction, resulting in damage to produce seals leak. In addition, the wheel paddle fast - opening also has secondary pressure relief and safety interlock (shockproof, anti-loosening) function, when the cylinder body also comes with pressure, the blind can not be opened, more to ensure safe operation.
