Definitions
- the invention relates to a valve for the metered filling of liquids in packaging, with a housing with a supply nozzle, front mouthpiece and outlet device, with a movably driven in the housing, engageable with a valve seat and in front a valve cone and behind it a thickened middle part and closing body with rear sealing devices.
- valves or metering valves used for this purpose have a housing in which a closing body, which is flowed with the liquid to be filled from the back via the feed nozzle, is intermittently moved backwards to open the valve and is pushed forward again. to close the valve.
- a known valve achieves the outflow of the liquid filling material at a low outlet speed with sufficiently large filling quantities, so that, for example, when filling milk, undesirably strong foam formation in the packaging is avoided.
- the known filling valve also fulfills a further condition, namely that undesired dripping of the liquid is prevented after the valve is closed.
- screens were previously arranged at the outlet-side end of the metering valve, while the known valve described at the beginning has an outlet plate at the outlet-side end of the mouthpiece, in which bores running parallel to one another in the direction of the longitudinal axis of the mouthpiece are arranged to form outlet holes, the diameter of which is between 1 mm and 5 mm.
- the outlet holes in the outlet plate of the known valve disadvantageously become clogged when liquids with a small fiber content are to be filled. This often happens when filling fruit juices that are deliberately made by the manufacturer with pieces of fiber and others 2 small particles should remain mixed.
- the known valve does not allow the filling of fruit juices or the like. If one were to enlarge the outlet openings in the known valve in order to reduce the risk of clogging, then the liquid in the space described would no longer hold on the rear side of the outlet plate after the valve was closed, and the undesirable dripping would result disadvantageously. Once there is one or even several outlet holes have become blocked, the filling accuracy of the known valve suffers with a further disadvantage.
- the flow jet of the known valve is disadvantageously often unsteady and has too great a surface roughness, so that the jet entering the packaging entrains too much air laterally. Due to the geometry of the known valve, the filling jet also disadvantageously contains a radial flow component, by means of which the emerging jet also becomes restless.
- the object of the invention is therefore to design the valve of the type mentioned in such a way that both water-like liquids and those with a fiber portion can be filled in a metered manner without the risk of clogging and, at the same time, a liquid jet with little to no trapped air at little without relative movements between the packaging and the outlet device Exit speed is reached.
- the thickened central part of the closure body is provided on its circumferential area with a ring of flow channels extending in the direction of the longitudinal axis of the mouthpiece, which openly open towards the front and back into the interior formed by the housing.
- the closing body works by opening and closing the valve in that the valve cone lifts off its seat or is pressed against the seat.
- the Strömungskanä 'le in this intermittently moving closure body, namely in the peripheral region of its thickened central part.
- the new valve is open, ie there is no longer a screen surface or an outlet plate, as was previously considered essential to prevent dripping.
- dripping is largely prevented even without the action of a surface tension on the liquid under the valve seat, and preferably the space under or in front of the valve seat is made as small as possible, and a reduction or elimination of the undesired dripping is found.
- the radial component of the inflowing liquid is converted into a laminar flow in the flow channels, so that the exiting liquid jet is so calmed that almost no air is trapped in the jet and could thus be entrained in the liquid.
- the escaping liquid jet has a low basic speed in large quantities, and dripping is minimized due to the small wetted area under or in front of the valve seat, although the valve cone arranged at the front remains surrounded by an annular wall so that there is no splashing when the valve is closed.
- the closing body has a front cylinder between the valve cone at the front and the central part and a rear cylinder between the central part and the rear sealing devices.
- the diameters of the front and rear cylinders are preferably smaller than that of the thickened middle part. This creates spaces in front of and behind the thickened middle part in connection with the approximately cylindrical jacket-shaped side walls of the housing, in which the liquid can move as it is forced on it by the geometry of the valve. On the inlet side so the liquid can behind the supply pipe spirally in the space are moved behind the thickened central portion, then in the Strömungskanä le 'enter.
- the liquid In the space around the front cylinder, which is approximately an annular space, the liquid can be carried on calmly, so that the flow can calm down to a certain extent.
- a desired effect the collecting and deflecting effect can be applied to the through-flowing liquid are successively applied, such as in the space rearwardly of the thickened central portion, the Laminier Ober the Strömungskanä 'le in the space in the area of the thickened center part and the settling in the front room in front of the thickened middle section.
- the feed nozzle is attached laterally so that the closing body can carry out its movement stroke directly in the outflow direction, ie in the direction of the longitudinal axis of the mouthpiece.
- the closing body largely fills the approximately cylindrical interior of the housing.
- the diameters of the Strömungskanä 'le are large compared to the outlet openings of known valves, amount to two to ten times, preferably three- to six times. Clogging of the individual flow channels by fibers or particles contained in the liquid to be filled is practically excluded.
- Central flow grooves and / or radially closed through holes are formed in the middle part of the closing body.
- the valve according to the invention functions with flow channels only in the form of flow grooves which are radially open from the outside; and in another embodiment, good results are also achieved with a valve, the flow channels of which are formed only by radially closed through holes.
- the new valve works best if both types of flow channels are arranged simultaneously and side by side.
- the radially closed through holes can be arranged at a slight radial distance from the outer circumference of the central part and the radially open flow grooves can each be configured between two through holes directly on the circumferential surface.
- both the ring of through holes and that of flow grooves are provided at the same time, then optimal opening areas are achieved in relation to the available cross section.
- the cross-sectional area to be flowed through then lies in a very small space in the area of these described rings, creating a large passage cross-section for the liquid to be filled. If one chooses as an example the embodiment in which only the flow grooves are used, then this can be so deep, i.e. execute with such a large radial depth dimension that there is a kind of blade or wing between two grooves.
- the flow channels in the peripheral area of the closing body act like a laminator.
- the length of the thickened central part of the valve body can be understood as a laminator. This laminator eliminates virtually any radial component in the flow of 'le Strömungskanä by the moving liquid.
- the essential part of the invention is this laminator, with which both water-like liquids and those with a fiber content or other solids are permitted to be filled. Due to the relatively large diameter of the flow channels in comparison to the previous filling valves, not only is clogging avoided, but it is also possible for the reasons explained above to form a largely air-free liquid jet with a smooth surface.
- the invention is furthermore advantageously characterized in that the sealing surface located in the transition region between the valve cone and the front cylinder can be brought into engagement with the valve seat in the mouthpiece and the valve cone projects into a free space between the valve seat and the front outer edge of the mouthpiece.
- the closing body has from front to back or in the most common vertical arrangement of the valve in the filling machines from bottom to top (against the direction of flow) behind the valve cone the front cylinder, behind the middle part and behind this the rear cylinder.
- the valve cone widens to an annular surface, which represents the sealing surface of the closing body. The vertical up and down movement or the intermittent movement of the closing body forwards and backwards engages this sealing surface with the valve seat in the mouthpiece or disengages it from this valve seat.
- valve cone now projects into a free space on the downstream side or in front of the valve seat. This space is located between the valve seat and a front outer edge of the mouthpiece.
- the liquid can flow out without significant throttling effects. This was not the case with the older valves, because a sieve, a perforated plate or the like was always arranged at the outermost end.
- the measures according to the invention teach that the liquid to be filled is only treated in the flow channels, ie only in the laminator, in which the radial component of the flow is eliminated.
- the actual outlet surface of the metering valve according to the invention is formed between the surface of the valve cone inside and the valve seat outside.
- the size of this ring area determines the passage cross section and thus the amount of liquid flowing per unit of time. Obviously there is a desire to make this passage cross-section as large as possible in order to achieve the lowest possible exit velocity for a large liquid volume. 6
- the measures according to the invention achieve excellent results compared to known valves.
- the free space in the region of the front end of the mouthpiece below or in front of the valve seat is advantageously kept small according to the invention. Then the dripping is negligibly small or even eliminated. If, after flowing past the valve seat, the liquid no longer needs to be influenced in any way, this free space can be briefly designed, as seen in the longitudinal direction of the mouthpiece. The shorter the ring-shaped outer wall, the smaller this free space. To avoid uncontrolled spraying of the fluid outwards on closing the valve, however, the wall of the 'mouthpiece can forward and thus are not made arbitrarily short the length of the free space. However, an optimization succeeds as soon as the spraying is eliminated. The free space then does not need to be designed any larger, and one can even coat or produce its inner surfaces with a material in which the liquids in question run off very quickly. Then no drops can form and the dripping stops.
- the free space between the valve seat and the front outer edge of the mouthpiece in its rear region, which is a quarter to two thirds of the axial length in front of the valve seat is formed by a surface which is spherical in cross section.
- the free space is divided into a spherical part, which takes up a quarter to two thirds of the total length, and an approximately cylindrical part, which takes up the remaining part of the axial length of this free space between the valve seat and the outer edge of the mouthpiece.
- the spherical rear area of the free space widens in cross section from a smaller inner angle ⁇ to a larger outer angle a.
- the smaller, inner angle ⁇ plays a role in the flow pattern of the liquid. If you change the front or lower or smaller angle ß, then you change the passage speed of the liquid. Tests have shown that a cheap embodiment works well when the angle ⁇ is between 8 ° and 30 °, preferably between 10 ° and 25 °. This considered favorable embodiment allows the transport of 1.5 liters of liquid in 5 seconds, in another embodiment even in 4.2 seconds.
- annular tear-off edge is attached within the free space between the valve seat and the front outer edge of the mouthpiece. This is set against each other by two approximately at 90 ° 7
- tear-off edge is annular. It is preferably in an approximately horizontal plane, i.e. transverse to the longitudinal axis of the mouthpiece; at the height that separates the front cylindrical part of the free space from the rear spherical part. This ring-shaped edge ensures that the liquid flowing out is torn off. As a result, the most forward cylindrical space is no longer critical with regard to the spray effect and the like.
- the invention is further advantageously designed in that the outer diameter of the thickened part of the closure body is larger than the outer diameter of the front cylinder and both outer diameters are larger than the outer diameter of the rear cylinder.
- the outer diameter of the front cylinder interacts both with the outlet cross section of the liquid at the valve seat and with the laminator.
- the outer diameter for example, the front cylinder not be reduced too much, because otherwise the annular Austrittsflä 'che for the liquid to'd small.
- said diameter is limited by the laminator, ie the diameter of the flow channels, to larger values, because the larger the outer diameter of the front cylinder, the smaller the area of the sum of the cross-sectional areas of the flow channels.
- the outer diameter of the thickened middle part of the closing body In the case of a valve, for example, one has chosen 47 mm as the outer diameter of the thickened middle part of the closing body. Its function is to receive the liquid supplied in a radial manner above the closing body in the space around the rear cylinder and to distribute the liquid evenly over the inlet surfaces of the individual flow channels.
- the circular line resulting at this height represents the rear or rear end of the laminator area, where an upper laminator edge results, so to speak. In operation, this should not come to lie behind or above the leading edge, which represents the lower edge or front edge of the feed connector, even when the closing body is pulled backwards. In the closed state of the valve, the upper laminator edge should therefore lie one stroke length in front of or below the inlet edge of the feed nozzle.
- the new valve works very well, ie in the rear part next to the rear cylinder, the liquid is collected and fed evenly to the flow channels, in the flow channels in the thickened middle part of the closure body the radial component of the flow is eliminated and the outflowing liquid is calmed next to the front cylinder.
- the length of the thickened portion of the closure about the 1, 5 times its outside diameter.
- the diameter of the through holes is approximately one tenth of the axial length of the thickened part of the closure body.
- the axial length of the thickened central part of the closure body is made as large as possible.
- this is a wish that cannot be realized in practice, because the structure and shape of the overall device and thus also of the housing means that the laminator area cannot be shaped indefinitely. For example, such a length must remain for the calming area that the liquid can flow smoothly around the front cylinder and the flow pattern can calm down further.
- its outside diameter i.e. that of the thickened middle part of the closing body, should be smaller than its length.
- the person skilled in the art also finds that the outside diameter of the front cylinder must not be larger than the inside diameter of the ring of the through holes.
- the outer diameter of the rear cylinder can therefore be smaller than that of the front cylinder, because in the rear area around the rear cylinder a valve seat and thus an outflow cross section are not formed as in the front.
- the person skilled in the art can advantageously design the valve further in that, according to the invention, the length of the thickened central part of the closing body is greater than the length of the front cylinder.
- a length of the flow channels is achieved, through which the individual liquid jets emerging from the through-holes can merge and merge into a single jet at the bottom at the front. This combined jet can then flow out around the front cylinder of the closing cone and forward around the valve cone in a calm form (flow pattern).
- valve seat By arranging the valve seat at a distance below the thickened central part of the closing body, the entire space located under the valve seat is emptied when the valve is closed and, with suitable measures, some of which are described above, designed freely to prevent dripping. In the area of the laminator, ie in the area of the flow channels, the surface tension of the respective liquid no longer needs anything special 9
