Definitions

  • the present invention relates to a filling valve for filling liquid-containing products, such as juices, still products, soft drinks, but may also contain pieces and long fruit fibers. It is currently known to use filling valves having a valve stem axially movable in the valve stem, wherein between the valve seat and the valve stem, an axial portion is formed, in which the product flows toward a located at the outlet end second sealing seat.
  • Such a filling valve according to the preamble of claim 1 was characterized by the US 5,137,187 presented.
  • This document describes a filling valve, in which two sealing elements are provided, which are arranged at a distance from each other on a valve lifter.
  • the valve stem When closing the filling valve, the valve stem is moved, wherein initially the upper sealing element comes in sealing position with its associated sealing surface while the lower sealing element has not yet reached its associated sealing surface.
  • the complete closing of the filling valve and the lower sealing element can reach its associated sealing surface, the upper sealing element is movably mounted on the valve stem.
  • a disadvantage of this arrangement is that the upper sealing element must be easily movable but also liquid-tight on the valve lifter, which exact fits and thus requires an expensive mechanical processing and beyond is also very susceptible to wear.
  • An alternative known filling valve also has a first sealing seat disposed in the axial portion upstream of the second sealing seat.
  • the first sealing seat and the second sealing seat are arranged and designed such that after closing the first sealing seat at the second sealing seat at the outlet end still a gap of 0.5 - 1.5 mm remains open, which acts as a gas barrier. If the first and second sealing seat were to be completely closed at the same time, the product would be splashed onto the mouth of the bottle and into the environment immediately during the closing process.
  • the gap on the second sealing seat which is often formed by a diameter-extended sealing area on the valve lifter and a circumferential shoulder on the valve seat, is in conflict with the overlying annular gap of the axial section formed between the valve lifter and the valve seat.
  • the gap on the second valve seat loses its effect or function as a gas barrier and the product located in the axial section above the annular gap and below the first sealing seat runs out.
  • the width of the annular gap and the size of the gap at the second sealing seat are additionally dependent on the viscosity and the surface tension of the products.
  • the problem here is the combined or alternating processing of high-viscosity or low-viscosity products, such as water, ice tea and peach juice with fruit, in a filling device. If, for example, the system functions perfectly in the case of highly viscous beverages, the beverage flows through the gas barrier, ie, over the gap of the second sealing seat, when low-viscosity products are to be filled.
  • the filling valve has at least one valve stem, which is arranged axially movable in a valve seat, wherein between the valve seat and valve stem, an axial portion is formed, in which the product flows to a second sealing seat, which is formed at an outlet end of the filling valve.
  • the second sealing seat is thus no longer left open a gap, but it is also closed, but in time after the first sealing seat, possibly in its own movement section. This ensures that after the closing of the first sealing seat of the filling process is completed and that in addition, the product located in the annular gap of the axial portion product is firmly trapped there first a gap on the second sealing seat remains so small that this as Gas barrier acts and counteracts gas entry. Finally, with the closing of the second sealing seat, which takes place only at a later time, no product is anymore splashed onto the underlying bottle or into the surroundings, even if this has a very low viscosity.
  • the advantage of the invention is that due to the temporally subsequent closing of the second sealing seat in the axial section - preferably in the annular gap - located between the valve seat and valve lifter product can not leak, and also no gas can rise in it.
  • the filling function of the filling valve is thus independent of the viscosity of the product within the usual ranges of viscosity in beverages.
  • valve stem is thus initially moved only to the extent that only the first sealing seat is closed and in the second sealing seat remains a gap, which acts as a gas barrier after reaching the capacity of a container to be filled. This means that the filling valve terminates the filling process without any spraying of filling material.
  • the filling valve according to the invention allows that the filling jet can be optimally designed for lowest turbulence and low foaming as well as high bulk performance and the processing of large particles.
  • the cumbersome consideration for a functioning gas lock is eliminated.
  • products with very different viscosities are manageable.
  • first sealing seat such that it allows a further axial movement of the valve stem in the closing direction.
  • the first sealing seat according to the invention thus has at least one highly elastic sealing element which can be deformed to such a degree after closing the first sealing seat, that it participates in the axial movement of the valve stem, without losing the sealing effect in interaction with the other sealing element of the first sealing seat.
  • Such a design of the first sealing seat is technically easy to implement because it requires no moving parts on the first sealing seat, because the further axial movement of the valve stem is based solely on the flexibility or deformability of the first sealing seat on the highly elastic properties of one or both sealing elements.
  • the sealing elements of the first sealing seat is arranged axially displaceably on the valve tappet or on the valve seat.
  • the axial displaceability makes it possible for the corresponding axially displaceable sealing element to join in the further axial movement of the valve stem after closing the first sealing seat, without losing the sealing effect in cooperation with the other sealing element.
  • the axially displaceable sealing element of the first sealing seat may be preferably held on an axially movable support, which is mounted axially movable either on the valve stem or on the valve seat.
  • the carrier may be formed by a metal sleeve, for example, which can be easily slidably provided on the valve stem or the valve seat.
  • the bellows also form the spring means, which defines a rest position for the wearer.
  • the sealing elements of the first sealing seat are formed by an elastic ring seal and a shoulder against which rests the ring seal.
  • the ring seal is preferably formed in this case on the valve stem and the shoulder is a, preferably significant, change in diameter at the valve seat.
  • it may be arranged on the valve seat and the annular seal on the valve stem and the shoulder on the valve stem.
  • the ring seal preferably includes an annular sealing lip which extends transversely to the direction of movement of the valve stem.
  • a sealing lip has due to their geometry and with appropriate thickness of the annular gap in the axial section between the valve stem and valve seat sufficient deformability to allow for concern with the shoulder further axial movement of the valve stem to close the second sealing seat.
  • the first sealing seat after its closing allows a further axial actuation of the valve stem in the closing direction of at least 1 mm. This makes it possible to set the time between the closing of the first sealing seat and the closing of the second sealing seat within wide limits.
  • the further axial actuating travel of the valve stem after closing the first sealing seat is 1.0-2.5 mm, preferably 1.5-2.5 mm.
  • This further axial actuation travel can be realized well by controlling the filling device in cooperation with an actuating mechanism for the valve tappet.
  • the time delay between the closing of the first sealing seat and the closing of the second sealing seat is realized in that the valve stem is simply moved in a sequence of movements.
  • the operation of the valve stem is realized by closing the first sealing seat and the subsequent further operation until closing of the second sealing seat by two separate controlled movements that the movement speed can be different in both processes.
  • the axial movement of the valve lifter can be held even after closing the first sealing seat for a short moment.
  • the radially outwardly extending highly elastic sealing lip 27 of the annular seal 26 can rest with its outer edge against the shoulder 28 of the valve seat 12 in the closed position of the first sealing seat 24.
  • Fig. 1a shows the position of the valve stem 14 during the filling of a product.
  • the sealing lip 27 of the annular seal 26 of the first sealing seat 24 is spaced from the shoulder 28 of the valve seat 12, as well as the teardrop-shaped thickening 32 at the lower end of the valve stem 14 of the sealing edge 34 of the second sealing seat 30.
  • the product feed 22 supplied product can thus without hindrance to the first sealing seat 24 and past the second sealing seat 30 in a below the filling valve 10 standing container (not shown) flow.
  • Fig. 1b shows the first phase when stopping the filling process.
  • the valve stem 14 in the valve seat 12 By a downward movement of the valve stem 14 in the valve seat 12, the valve stem has been moved down so far that now the sealing lip 27 of the ring seal 26 of the first sealing seat 24 rests against the shoulder 28 of the valve seat 12. This closes the first sealing seat 24, while the second sealing seat 30 is still open a gap.
  • the remaining gap between the teardrop-shaped thickening 32 of the valve stem 14 and the sealing edge 34 of the valve seat 34 preferably has a size of 0.5 - 11 ⁇ 2 mm. This gap acts as a gas barrier, as a result of which gas can not penetrate into the annular gap 36 located above the second sealing seat 30. Premature emptying of the axial region or annular gap 36 is thus excluded.
  • valve stem 14 is further moved down until the teardrop-shaped thickening 32 abuts against the sealing edge 34 of the second sealing seat, that is, the second sealing seat 30 closes.
  • Fig. 1c shown.
  • the axial section or annular gap 36 is closed at the top by the closed first sealing seat 24 and at the bottom by the second sealing seat 30th
  • the elastic sealing lip 27 deforms so much that they, as in Fig. 1c is shown no longer extends radially outward, but is bent plate-shaped according to the further axial movement of the valve stem 14 after closing the first sealing seat 24.
  • the filling valve shown in the embodiment allows for the non-spilling filling of products of liquid-containing products containing solids as well as products of different viscosity.
  • the opening of the second sealing seat for a new filling process is reversed. First, the second sealing seat 30 and only when the corresponding axial movement of the valve stem, the deformation of the sealing lip 27 in Fig. 1 is omitted, it lifts off from the shoulder 28 of the first sealing seat 24, so that the first sealing seat 24 is opened only after the opening of the second sealing seat 30.
  • the time delay can also be adjusted again by controlling the filling device by means of movement control of the valve tappet.
  • Fig. 2 shows one too Fig. 1 largely identical view of a second non-inventive embodiment in which identical or functionally identical parts are provided with identical reference numerals.
  • first sealing seat 42 of the filling valve 40 off Fig. 2 designed differently than the first sealing seat 24 from Fig. 1 ,
  • the first sealing seat 42 of the filling valve 40 from Fig. 2 has on the valve seat 14 a to the embodiment of Fig. 1 identical shoulder 28 as a sealing surface.
  • an annular sealing element 43 is arranged with an axially displaceable support 44 on the valve stem 14.
  • Carrier 44 is held axially movably on valve tappet 14 via an upper bellows 46 and a lower bellows 47 and is tightly connected to corresponding upper and lower portions of valve tappet 14 and thus sealed against the product.
  • the two bellows 46, 47 are made in one piece, as shown in the FIG. 2 is shown.
  • the carrier 44 carries on its outer circumference a seal 48, for example an O-ring seal or a flat gasket, which rests against the shoulder 28 of the first sealing seat 42 when closing the first sealing seat 42.
  • Fig. 2a the filling valve 40 is shown in the open position, that is, both the first sealing seat 42 and the second sealing seat 30 are open.
  • Fig. 2b the valve tappet 14 moves down so that first the seal 48 of the carrier 44 of the annular sealing element 43 of the first sealing seat 42 comes to lie sealingly against the shoulder 28 of the first sealing seat 42 formed on the valve seat 12.
  • a gap of about 1 mm is still present, which acts as a gas barrier and a splashing of product on an underlying bottle or in the Environment counteracts.
  • the valve tappet 14 is then moved further downwards so that now the teardrop-shaped widening 32 of the second sealing seat 30 comes to rest on its sealing edge 34, whereby the second sealing seat 30 also closes.
