Abstract

The invention relates to an inlet valve, a mixing device and a control method for introducing a powdery substance into a liquid present in a container of the mixing device. The present invention has the object of developing the inlet valve, the mixing device, the control method and the method so as to avoid the formation of dead space in the region of the internal wall of the container at the entry point for the powder, and clumping and blocking of the powder at the entry point and in the inlet valve, and so as to ensure reliable and smooth introduction of the powder into the liquid and simple adaptation to different powdery substances. Furthermore, the configuration of the inlet valve aims for a low-wear and replacement-friendly arrangement of the seat seal. This is achieved, in terms of the device, with an inlet valve in which, inter alia, ∙ the valve seat (2a) forms a seat opening (2b) through which the powdery substance (P) is introduced into the liquid (F), ∙ the seat opening (2b) with the valve plate (8a) can be changed between fully closed (shut position) or fully opened (open position), ∙ the seat opening (2b) is arranged in and flush with a region of extent of a wall of the container jacket (100.1) or of the container bottom (100.2), ∙ the valve closing member (8) can be transferred by means of the control device (30) into the shut position and into the open position, ∙ the control device (30) has at least one signal receiver (16), ∙ the at least one signal receiver (16) is a measurement device for the mixing parameters composition and nature of the powdery substance (P), throughflow of the powder (P) in the inlet valve (20), pressure in the mixing device (1000) in the region of the seat opening (2b) and/or temperature of the liquid (F), and ∙ the shut position or the open position of the inlet valve (20) can be set during the introduction procedure depending on the mixing parameters.
