    In packing machines of the type which manufacture packing containers with liquid contents a filling pipe with a valve arrangement situated at the outlet end is frequently used. The valve arrangement in accordance with the present invention comprises a movable valve element which is manoeuvred with the help of pressure variations in the filling pipe. The movable valve element is cup-shaped and is adapted so that it is lifted through excess pressure in the filling pipe from a fixed disc-shaped seat so that an annular discharge opening results.

    The liquid pipe 6, while the liquid part 51 of the prol, enters through one nozzle 5 and the solid part through another nozzle. The liquid part of the product is supplied in a continuous flow, which flows around the valve block 8, the solid part of the product is supplied by a dosing pump periodically: Valve elementleite 8 is: C in the lower positionJ and its sealing ring 9 is tight to the sealing surface 19 valve -: Element 7 After the clips form a transverse seam on an iTpy6e of packaging material, the invention relates to a filling technique and can be used, for example, in packaging machines.
    The purpose of the invention is to improve the reliability of the packaging of liquid products containing solid particles.
    FIG. 1 is a schematic diagram of the packaging magazine; la fig, 2 - nilssny end of the tube of packaging material with a valve mechanism, a section; Fig 3 - valve mechanism, section; in fig. 4 - then, an embodiment
    The valve mechanism to the packaging machine consists of a roll 1 for packaging material 2, a reversing roller 3, cutting off the burners m 4 of the packaging container 5, a Bvrtikalno installed feed tube
    6 and located at its lower end with the possibility of j interconnection between two valve elements
    : 7 and 8, while the valve element 7 is fixedly supported and the valve element 8 is imitated with a POSSIBILITY of movement in the axial direction relative to the valve element
    7 for the formation of an annular gap between them during the ejection of the product,
    The valve element 8 of the mocquet can be mounted on the feed pipe b and have an annular form and around its circumference a sealing ring 9 can be placed. The solid part of the product interacts, which, acting on the valve element 8, lifts it, forming an annular hole. After that it it mixes with the liquid part of the product, which comes with a greater speed; this ensures more efficient mixing. Under the combined force of gravity and pressure of a part of the product, the valve element 8 is pressed down and overlaps AET delivery solid part, the valve element 8 remains in the closed position until the embedded guide delivery stroke of the metering pump., 9z.p., 4 ILA
    with a fixed valve member 7 and a protrusion 10 with a seal having a conical or curved shape.
    The feeding tube 6 can be made in the form of two concentrically arranged branch pipes 11 and 12, while the valve element B is fixed on the outer surface of the branch pipe 11. The lower end of the branch pipe 12 can be made narrowing towards the outlet opening, the fixed valve element 7 in the upper parts can be made goat.,
    and its diameter is less than the diameter of the pipe no. 12.
    The valve element 7 can be installed on the lower end of the nozzle 12, and the valve element 8 can be

    The mechanism works as follows.
    The packaging material web 2 is fed by cutting zazhin 4 and forms a tube 13, continuously moving downward, with containers formed at its lower end for filling with product. The product is continuously fed to the bottom.
    pipes 13 from feed pipe 6. The liquid part of the product comes from tank 14 through a pump or a constant flow valve 15 and pipe 12J and the solid part goes from tank 16 through pipe 11 to the lower end of the feed pipe 6 and is discharged through hole 17. part of the product flows through the pipe 12 on the outer surface of the valve element 8 and exits through the opening into the pipe 13 from the packaging material. This flow is continuous and therefore the lower end of the pipe 13 is filled with a liquid, part of the product. The flow of the solid part of the product is interrupted for some time, and the metering pump 18 remains at rest
    As a result of the fact that the solid part of the product does not flow through the pipe 12, the valve element 8 is
    in the lower position and its sealing ring 9 fits snugly to the sealing surface 19 of the valve element 7.
    After the cut-off clips 4 form a transverse seam on the pipe 13, the metering pump 18 supplies from the reservoir 16 to the nozzle 11 a predetermined amount of solid part which acts on the inner, surface of the valve element B. At the same time, overcoming the force of gravity and force, created by the liquid part rises. At this time, the sealing ring comes off from the sealing surface 19 of the valve element 7, forming an annular opening.
    The solid part of the product flows outward in the form of a conical annular flow between the sealing ring
    9 and the sealing surface 19 and comes into direct contact with the liquid part flowing with greater speed, mixes with it and flows through the opening 17. As a result of the fact that the solid part of the product is fed into the liquid part,
    the latter comes at a high speed, efficient mixing takes place and at the same time the liquid part carries away solid particles, preventing them from sticking to the lower end of the feeding tube. b. Since the inner surface of the housing 20 is conical, raising the valve member 8 somewhat reduces the annular opening between the outer surface of the valve member 8 and the inner wall of the housing 20.
    As soon as a predetermined amount of product is supplied through pipe 11, the pump 18 is turned off, the pressure in the filling pipe decreases and the solid part of the product can no longer

    lift the valve 8 to the upper position. Under the joint action of the force of gravity and pressure of the liquid part of the product, the valve element 8 is pressed down and blocks the flow of the solid part of the product. This also contributes to the metering pump 18, which creates a vacuum in the pipe 11 during the reverse stroke. The valve element 8 remains in the closed position until the vacuum in the pipe 6 changes as a result of the next injection stroke of the metering pump 18.
    In another embodiment of the valve mechanism (Fig. 4), the solid part of the product flows into the nozzle 12. At the same time, as in the first embodiment, the expanded part of the nozzle 12 is located at the lower end of the supply pipe and serves as the housing 20 "Valve element 7 is located at the bottom end of the feeding tube 6 and can be made in one piece with the body 20,
    5, the lower end of which narrows towards the outlet 17. Thus, the valve element 7 is a part of the lower end of the nozzle 12 and can be made in one piece with it. The sensor 19 on the surface 19 of the valve 7 protrudes in the form of a ring around the outlet and interacts with the sealing ring 9 of the valve 8, which abuts against the pipe 11 and can be moved in the vertical direction. The sealing ring 9 has a cylindrical outer surface, forming the lowest closing part of the conical or curved ° linear edge of the protrusion 10 of the valve element 8
    In the center of the valve element 8 is provided with a vertical hole, which is a continuation of the pipe 11.
    5 Through this hole the liquid part of the product can continuously flow at the desired speed. The nozzle 11 may be provided with a finger 21, mounted inside it concentrically
    0 at the level of the narrowed zone 22 of the opening of the valve element 8. When lifting the valve element 8 to pass the solid part of the product, the gap between the finger 21 and the narrowed zone
    5 22 expands and the downward force decreases. When the flow of the solid portion of the product is interrupted, the metering pump 18 creates a short-term vacuum on the underside.

    valve element 8 and thus initiates a downward movement of valve 8. This means that the product between the finger 21 and the constricted zone 22 is successively reduced, which increases the pressure in the pipe 11, and it acts on the valve element. 8, again lowering it to the closed position. The increased pressure in 1 tube 11 contributes to the acceleration of the flow of liquid, and this flow can be used for cleaning. To direct the flow of fluid to the inner surface of the pipe 13 of an investment material, an expander, for example a conical element 1:: can be installed near the lower end of the valve element 8.
