THE DESIGNS AND DEVELOPMENT OF ROTARY AIRLOCK VALVE
Rotary airlock valves are widely used device in material handling processes and convey material to maintain constant air pressure between inlet and outlet ports. This valve can operate as an airlock, feeder or combination of feeder airlock in a pressure conveying system. A rotary airlock valve acts as lock to the air where an air seal is needed between ports. Design and Construction- · Rotary airlock valves have a heavy cast housing which consist a body and two end covers, an internal rotating rotor and drive package. The body has two parts an inlet and outlet that allow entering the material and exit valve. The rotor shaft has multiple vanes and extends out through the housing to external bearing that supported by end covers. · Inside housing, the vane radiate out from shaft to the housing. The space between rotor vanes creates pickup material at inlet port and transport to the outlet port. The drive package consist a electric motors that connect to the ro
