Definitions

  • the invention relates to a metering valve on metering pumps according to Preamble of claim 1.
  • a metering valve of this type in particular for metering flowable, lumpy solid particles, such as jam, yoghurt or the like, is known from DE-A-195 04 546 C1.
  • This known metering valve also works like a so-called rotary slide valve (see, for example, US-A-3,228,412), but in such a way that the cam, similar to a finger held in front of an opening, closes the supply opening and pivots it for the purpose of opening and thereby a relatively large part of the housing space is released, whereby, as has been shown, the dosed filling material can flow around the cam in the open position without any risk of clogging.
  • the actual metering is carried out by correspondingly clocked actuation coordination by the metering valve and a metering pump arranged above the opening of the inflow channel on the valve housing, which is not particularly shown in DE-A-195 04 546.
  • This metering valve works absolutely satisfactorily with regard to the requirement to avoid blockages in the case of difficult metered items of the type mentioned above and to create a large flow space in the housing space when it is open.
  • the disadvantage here is that two such metering valves, which are not exactly cheap, must be assigned to a metering pump, namely one for the suction process and one for the exhaust process.
  • the arrangement of two such metering valves for each metering pump requires space in the area above the filling station, for example a so-called FFS packaging machine, and also a corresponding double drive effort for two such metering valves.
  • the invention is accordingly and starting from the metering valve type mentioned the task, while maintaining of its benefits including easy cleaning to redesign and improve such a metering valve, that one for a dosing pump with only one dosing valve for the Suction and exhaust process comes out, and also if necessary Suction and discharge openings of the metering valve at the same time should be lockable.
  • the two inflow and outflow channels are preferably vertical and parallel arranged side by side in the housing, if possible only weakly curved flow paths in the valve from the suction side to the Pump and reach from this to the discharge opening.
  • the metering valve according to the invention and its advantageous embodiments are subsequently based on the graphic Representation of exemplary embodiments explained in more detail.
  • Certain metering valve still consists of a Inlet and outlet channels 9, 10 containing housing 2 with a one with respect to the diameter D of the inflow and outflow channels 9, 10 larger diameter, cylindrical cavity 8 of the housing 2 pivoting locking part 1.
  • This locking part 1 is as Head of a protruding into the housing 2 sealed, with respect Reduce the diameter D1 of the cavity 8 Control shaft 3 formed.
  • the actual closing surface 6 of the Locking part 1 extends parallel to the cylindrical wall 7 of the cavity 8, and the closing part 1 is covered in the form of a on the pivot axis 4 of the control shaft 3 from this formed on one side oriented cam 5.
  • the radius R of the closing surface 6 of the cam 5 is somewhat smaller than the radius R 'of the cavity 8 outside the range of the cylindrical Dimensioning plane ZE 'of both openings 9', 10 '.
  • the two Inlet and outlet channels 9, 10 in the housing 2 essentially opposite a pump suction and discharge opening 11 are arranged.
  • the two adjacent to each other through an intermediate web 12 spaced openings 9 ', 10' of the inflow and outflow channels 9, 10 are in the cylindrical adjustment plane ZE of the closing surface 6 of the cam 5 arranged.
  • the closing surface 6 dimensioned in its arc length L such that, with a corresponding Position of the cam 5, the two openings 9 ', 10' at least are closed (total closed position according to Fig. 4).
  • the maximum possible arc length L extends from one or the other opening edge 11 'of the pump suction and Ejection opening 11 to the inner opening edge 9 '' ', 10' '' one or the other opening 9 ', 10' (see Fig. 5).
  • Drainage channels 9, 10, not as shown in FIGS. 1 to 4 mandatory vertically opposite the suction and discharge opening 11 and must be arranged parallel to each other, which is preferred is, but also, as shown in Fig.6, with appropriate Design of the bottom of the housing can be arranged can.
  • the Radius R of the closing surface 6 of the cam 5 is smaller than the radius R 'of the cavity 8 outside the range of the cylindrical Arrangement level ZE 'of the openings 9', 10 'of the two Inflow and outflow channels 9, 10, but here in the area outside the arrangement level ZE ', in the middle, the pump suction and discharge opening 11 is arranged.
  • Fig.3 is both the piston K of the metering pump P and also the closing part 1 of the metering valve can be flushed around freely. Due to the total closing ability of the metering valve (see FIG.
  • FIG. 7 Only for the sake of completeness is a longitudinal section in FIG. 7 represented by the metering valve, which is also present Case consists of two parts, i.e. from the to the drive side completely open housing 2, which on this side by the attachable bearing part LT for the closing part 1 completed becomes.
  • the bearing part In the case of sterile operation, the bearing part is LT with connections and channels AK for the passage of a suitable Provide sterile.
