Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • a beer line to be cleaned is connected to the intermediate housing of the device; at the other end, these beer lines are connected to one another, so that a cycle results.
  • the cleaning liquid such as lye, acid, rinse water and disinfectant solution
  • the cleaning liquid is fed to the four-way switch valve via the inlet connection.
  • the cleaning liquid first flows through a valve opening into the channel opening into one end face of the piston and from there through the first intermediate housing into one beer line and further through the other beer line, the other channel and the second valve opening back into the drain connection.
  • Cleaning bodies designed as sponges are taken along. As soon as they hit the piston of the changeover valve, it is moved and the flow direction is reversed.
  • the drain connection is in the In case that rinsing water is used as cleaning liquid, it is connected to the normal house routine. In the case of lye, acid and disinfectants, these are each returned to a designated container, where they are collected and reused.
  • one valve opening is connected to the inlet connection, while the other is connected to the outlet connection via a connection space formed in the socket of the changeover valve housing.
  • the manufacture of such a housing is technically complex and requires the production of several individual parts that have to be assembled in a further operation. To avoid leaks, these individual parts must be manufactured with great accuracy. This high workload during the manufacture of the individual parts of the changeover valve and the subsequent assembly of the individual parts causes high costs.
  • DE-PS 689 234 discloses a device for cleaning tubes, which is connected to form a closed circuit at the two ends of the pipeline to be cleaned and to a pressurized liquid source.
  • This device has a housing with a central bore which has six axially offset openings which are connected in pairs by housing channels.
  • a slide is arranged in the central bore, which overrides part of these openings and carries rods with attached sieve plates with the same diameter as the slide at both ends. If the sieve openings are closed by the cleaning bodies carried along with the liquid flow, a displacement of the slide is brought about, which has the consequence that the liquid flows in the opposite direction of flow.
  • the invention is based on the object of specifying a cleaning device of the type described at the outset, which has a simple structural design in a functionally reliable manner.
  • the bush Since the bush has the simple geometric shape of a continuous hollow cylinder, it can be easily removed from a shape. This also applies if it is molded in one piece with the housing, i.e. if it is completely manufactured in one and the same operation. Since these housings are usually made of plastic, the bushing and the housing can be produced by injection molding. In addition, this socket is characterized by high stability. Since it is manufactured in a "cast", seams are avoided, which can easily lead to leaks. This configuration of the bushing is possible because, according to the invention, the connection space is arranged within the piston cross section. Moving the connection space from the housing bushing to the piston also results in a smaller, more compact housing. Overall, the device is easy to manufacture and therefore inexpensive to produce. Because of the high precision that can be achieved during production, the switchover takes place with a high degree of certainty.
  • valve connector can be used later.
  • its position can be adjusted with respect to the valve openings.
  • the cleaning liquid is led from the inlet connection directly to a valve opening without the cleaning liquid being lost.
  • the configuration of the piston according to claim 4 creates a possibility of keeping leakage losses in the changeover valve even smaller in a simple and inexpensive manner. Because the throttle gap between the valve stub and the nutrand also contributes to the sealing.
  • connection devices with the housing according to claim 7 also opens up the possibility of injection molding the connection devices onto the housing. For this reason, housings and connection devices can be produced inexpensively in a single operation.
  • the design of the connection devices as ring elements allows the usually essentially cylindrical intermediate housing to be coupled to the valve housing.
  • the housing can be integrally connected to the housing by the circular arc-shaped ring segments and the resilient intermediate pieces.
  • the associated intermediate housings have, for example, a flange which is pressed into the ring element by an axial movement and is locked there by the spring force of the intermediate pieces.
  • the resilient intermediate pieces are separated by recesses from the outer wall of the housing.
  • the circumferential housings provided for this purpose have cams fitting into these recesses.
  • the intermediate housing can be easily connected to the housing by hand.
  • the cams of the intermediate housing are pressed axially into the resilient intermediate pieces. These are deflected in the radial direction and spring back to their original position as soon as the cams have slid into the recesses.
  • the resilient intermediate pieces lie on a circular line with a smaller inner diameter than the ring segments, so that the cams of the intermediate housing come to lie in the axial direction under the intermediate pieces in the assembled state of the device.
  • the length of the ring segments in the circumferential direction is advantageously greater than the length of the cams of the intermediate housing.
  • the length of the intermediate pieces corresponds essentially to the length of the cams, the distance from the housing, that is to say the height of the recesses, is less than the height of the cams.
  • the required torque can be applied particularly easily by hand if the intermediate housing has longitudinal ribs on the outer circumference.
  • the resilient intermediate pieces have two different wall thicknesses and thus form a stop for the longitudinal ribs.
  • the switching valve can be installed stationary, for example in the beer cellar.
  • the fixation of the changeover valve on a base prevents the changeover valve from "wandering" during its operation.
  • the surface course of the supports allows them to be injection molded in one piece with the housing and still be easily removed.
  • the duration of this switchover process is influenced by the number of openings in the end face of the piston, the number and size of the cleaning bodies and the pressure of the flowing cleaning liquid. If the orifices are distributed over the entire end face of the piston, for example if the end face of the piston is designed as a sieve, it takes a certain time, depending on the number of cleaning bodies, until all of the orifices are closed and the piston is displaced. With a small number of cleaning bodies, the switching process is slow.
  • the reduction of the piston end face compared to the piston is a structurally very simple measure in order to carry out the switching process with high precision and with little delay.
  • the intermediate housing is made of transparent plastic, the position of the piston is visible from the outside.
  • the orifices are limited to central regions of the end faces, there is a central flow of the cleaning liquid in the intermediate housing in the direction of the end face of the piston. With the help of this centric flow, the cleaning bodies can be guided until shortly before hitting the end face. This results in an exact assignment of the cleaning body and the end face of the piston. Even a cleaning body can be sufficient to cover the mouth.
  • the concave design of the end faces of the piston also serves for the exact guidance of the cleaning bodies, which are, for example, ball-shaped, on the end faces of the piston.
  • the cross-slot-shaped mouth according to claim 18 can be arranged at the lowest point of the concave curvature of the end face. With the help of the centric flow, this mouth can be closed with a single cleaning body. As soon as it hits the muzzle, the piston is immediately moved without delay. Furthermore, the cross-slit design of the mouth on the end face is very easy to produce by injection molding since only a stable core is required, which is characterized by high stability.
  • the tapered shaft according to claim 19 results in material recesses in the body, through which material accumulations can be avoided and better spraying results can be achieved.
  • a changeover valve 1 has a valve housing 2 with an inlet connection 3 and an outlet connection 4. On the outside of the housing, connection devices 9 for intermediate housings 10, 10 'are arranged, which connect pipes, not shown, to the changeover valve 1.
  • the connection devices 9 have ringseg elements 11, which are connected by resilient intermediate pieces 12.
  • a piston 5 is slidably mounted, in the end faces 7, 7 'each a cross-shaped channel 8, 8' opens.
  • a valve body 39 with a longitudinal groove 17, in the bottom of which two valve openings 18, 19 open (FIGS. 3 and 4). These are connected via channels 8, 8 'to the end faces 7, 7'.
  • the mouths 6, 6 'of the channels 8, 8' are cross-shaped (Fig. 6).
  • the valve body 39 has a smaller diameter than the piston sections 5a, 5b.
  • connection space 27 between the valve body 39 and the bushing 26 of the housing, which is designed as a continuous hollow cylinder and is connected to the drain connection 4.
  • the connecting space 27 is delimited at both ends by annular shoulders 40, 41. These wear on their periphery for sealing against the bush 26 in an annular groove sealing elements 42, 43 and determine the size diameter D of the piston 5.
  • the end faces 7, 7 'of the piston 5 are concave (Fig. 6).
  • the inlet connection 3 shows on its inside an internal thread 13 into which a valve stub 14 is screwed.
  • the valve stub 14 projects with its one end 15, which has a smaller diameter than the other end 16, down to the bottom of a longitudinal groove 17 of the piston 5. To fix its position, it is locked with the aid of a nut 35.
  • the cleaning liquid flows from the inlet connection 14 to the valve opening 18 opening into the bottom of the longitudinal groove 17 (FIG. 5).
  • the other valve opening 19 is connected to the drain connection 4.
  • the intermediate housing 10, 10 ' have at one end work connections 20 to which the pipes to be cleaned are connected. At their other end they carry cams 21, by means of which the intermediate housing 10, 10 'are attached to the valve housing 2 of the cleaning device 1.
  • the cams 21 engage in recesses 22 which are formed in that the resilient intermediate pieces 12 of the ring elements 9 are at a distance from the housing 2.
  • the intermediate pieces 12 have semicircular recesses 24, which in the embodiment shown serve as a stop for longitudinal ribs 25 of the intermediate housing 10.
  • the diameter d1 of the end face 7, 7 'and the slightly larger diameter d2 of the interior 44, 45 of the intermediate housing 10, 10' are smaller than the largest diameter D of the piston 5th
  • Fig. 3 the entire cleaning device is illustrated in section.
  • the housing 2 has a continuous, hollow cylindrical bushing 26.
  • the piston 5 is slidably mounted in this bushing 26, the two piston sections 5a and 5b of the largest diameter being guided in the bushing 26 in a sealed manner.
  • the right-hand valve opening 18 stands with that which is not visible in FIG. 3 Valve socket 14 in connection, while the valve opening 19 is connected to the drain port 4 via an annular connection space 27.
  • the cleaning liquid flows through the valve stub 14 and the valve opening 18 into the channel 8 opening into the end face 7 of the piston 5, through the cross-shaped mouth 6 into the interior 44 and from there into the right intermediate housing 10 the cleaning liquid carried.
  • the cleaning liquid flows into the intermediate housing 10 'and from there via the channel 8' to the valve opening 19 and via the connection space 27 in the drain port 4.
  • the cross-slot-shaped mouth 6, 6 'in the end face 7, 7' of the piston 5 is closed by the cleaning body 36.
  • the opening of this mouth 6 ' takes place immediately and without delay due to the small diameter of the end face 7 and interior 45, the central flow in the interior and the concave formation in the end face 7 of the piston 5.
  • valve stub 14 is now also available the Valve opening 19 and the valve opening 18 via the connection space 27 with the drain port 4 in connection.
  • the direction of flow of the cleaning liquid is reversed and as soon as the cleaning body 36 meets the cross-shaped mouth 6 'in the concave end face 7' of the piston 5, it closes the mouth 6 and there is a displacement of the piston back into that shown in Fig. 3 Position. This switching process is repeated during the entire cleaning time which is considered necessary for cleaning the pipeline.
  • the cleaning device 1 shown in the drawing shows supports 30 which consist of a leg 31 extending from the housing 2 at an obtuse angle and a second leg 32 running parallel to the base.
  • the legs have surfaces parallel to the socket axis, so that easy removal is possible.
  • a reinforcing rib 33 extends between the legs 31 and the housing 2 and is arranged in a plane perpendicular to the socket axis.
  • the second legs 32 which run parallel to the fastening base, have bores 34 for fastening means, not shown in detail.
  • the longitudinal groove 17 has a width which is equal to the diameter of the valve stub 14 and is delimited at the ends by half-cylindrical surfaces 46 which correspond to the circumferential surface of the valve stub. This in connection with the exact axial adjustment of the valve stub results in a very good seal of the incoming cleaning liquid.
  • the surfaces 35 form a stop limiting the axial movement of the piston 5, so that it always comes to rest in a position in which the valve stub 14 is exactly aligned with the respective valve opening.
