A control mechanism (20; 70) and a method for use in an installation for transporting bulk material, granular material or powdery material through a conveyor line (1) with the aid of a pressurized gaseous medium. The control mechanism (20; 70) is arranged for being connected to the conveyor line (1) for the purpose of introducing a pressurized gaseous medium (15) therein and comprises a connecting opening (24) for connecting the control mechanism (20; 70) to an inlet (25) in the conveyor line (1), an intake (26) for gaseous medium (15), which is in communication with the connecting opening (24), valve means (28; 71), which operatively engage the intake (26), and means (31, 32, 35, 50, 51; 32) for controlling the valve means (28; 71) associated with the pressure of the gaseous medium in the conveyor line (1). The control mechanism (20; 70) is arranged for directly controlling the control valve (28; 71) in response to the sensed pressure in the conveyor line (1) for the purpose of metering the pressurized gaseous medium (15) that is being delivered thereto.
A control mechanism for use in an installation for transporting bulk material, granular material or powdery material through a conveyor line with the aid of a pressurized gaseous medium, which control mechanism is arranged for being connected to said conveyor line for the purpose of introducing a pressurized gaseous medium therein, characterized in that said control mechanism comprises a connecting opening for connecting said control mechanism to an inlet in the conveyor line, an intake for gaseous medium, which is in communication with said connecting opening, a control valve which operatively engages said intake, and means for sensing pressure of the gaseous medium in the conveyor line for directly controlling said control valve in response to said sensed pressure for the purpose of metering the pressurized gaseous medium that is being delivered to said connecting opening via said intake.
An installation for transporting bulk material, granular material or powdery material through a conveyor line by means of a pressurized gaseous medium, from an intake point to an outlet point thereof, comprising control mechanisms according to any of the previous claims, which control mechanisms are connected to the conveyor line between said intake point.
