Definitions
- the invention relates to a filling spout and, in particular although not exclusively, to a filling spout for a weight metering machine.
- document FR-2 688 196 discloses a filling spout producing a jet of liquid at high flow rate in laminar regime.
- This spout comprises a tubular body and a calibrating member movable inside the body between a low position in which it closes a body orifice 10 and a high position in which it allows the flow of the liquid.
- a conical inner wall portion of the tubular body adjacent to the flow port and a conical sizing portion of the sizing member define between them an annular space of decreasing section up to the flow port.
- This annular space has a sufficient length relative to the width of the annular space taken in a radial direction at the level of the flow orifice to obtain a laminar flow even for high flow rates.
- a calibration member having a low taper that is to say the angle of the lateral surface with respect to the axis is small.
- the calibration part comes to bear on the edge of the flow orifice to ensure the closure of the spout.
- a small taper of the calibration part implies a large stroke of the calibration member to obtain full opening of the filling spout.
- a large stroke of the calibrating member is incompatible with the control devices usually used to adjust the position of the calibrating member.
- An object of the invention is to propose a filling spout producing a jet at high flow rate
- a filling spout comprising a tubular body having a calibration portion and terminated by a flow orifice, and a movable valve inside the tubular body and having a conical sizing part followed by an end part having a section decreasing more rapidly than the sizing part, the sizing part of the tubular body and the sizing part of the valve delimiting between them an annular space of decreasing section towards the flow orifice of the tubular body, this annular space having, relative to the width taken in a radial direction at a lower end of the annular space, a length sufficient to obtain a laminar flow in the annular space in which the calibration portion of the valve has a lower end having a radius greater than the radius of the flow orifice.
- the strong decrease in the section of the terminal part allows a maximum flow rate to be obtained with a short stroke of the valve and it has been found that, surprisingly, the increase in section which results immediately upstream from the orifice flow did not destroy the laminar flow regime obtained by the calibration part.
- the invention thus achieves a compromise between the conditions for optimum flow and industrial constraints.
- the filling spout comprises a tubular body 2 having a flow orifice 3 for the outlet of the liquid to be packaged.
- the spout further comprises a valve 4 movable inside the tubular body along a vertical axis 6 thereof.
- the left half of the figure shows the valve 4 in the low position in a position for closing the lower orifice 3.
- the right half of the figure shows the valve in the high position in a position allowing the maximum flow of the liquid to be conditioned .
- the tubular body 2 comprises a conical calibration part 8.
- the valve 4 comprises a conical calibration part 10 of the same conicity as the calibration part 8.
- These two parts 8 and 10 define between them an annular space of decreasing section in the direction of the flow orifice 3.
- This annular space has a length L along the axis 6, preferably at least equal to approximately eight times the width 1 . of a lower end of the annular space taken in a radial direction.
- the tubular body 2 has a terminal part 12 adjacent to the lower orifice 3.
- the valve 4 has a terminal part 14, conical in the illustrated embodiment and having a taper greater than that of the calibration part 10 of the body tubular 2.
- the end part 14 forms an angle of 60 ° with the axis while the conical calibration part 10 forms an angle of 16 ° with the axis.
- the radius R of the calibration part 10 at the lower end of the annular space is greater than the radius r of the flow orifice 3 of the tubular body so that the end part 14 closes the lower orifice 3 when it comes into contact with the terminal part 12 of the body 2.
- the taper of the end portion 14 is calculated so that at the end of the opening stroke this end portion is completely contained inside the tubular body without protruding from the flow orifice 3 and the calibration part 12 has a curved S-shaped profile along a section through an axial plane. This profile has two opposite curvatures, a concave upper curvature contiguous to the conical calibration part 8, and a convex lower curvature adjacent to the flow orifice 3.
- the terminal part of the valve may have a shape other than conical, for example a curved profile along the curved profile of the end part of the tubular body 2.
- the end part of the tubular body 2 may have a conical shape whose taper may be close to or identical to the taper of the terminal part of the valve.
