    The invention relates to a so-called diverter for installation at a branching point of a pipe system, in particular in a pneumatic conveying system, with a Hauptrohrstutzen which branches in a switch box in at least two side pipe sockets, and hineinra with a between the sockets and hineinra in the junction box Switching gate, with which the flow paths can be switched to the pipe socket.
    Diverter valves of the type mentioned are particularly needed in pneumatic För-dersystemen, for example, for automatic food distribution in stables. In this case, a switch valve is placed in different positions within a switch box so that material flows such as air, bulk materials such. As feed, but also liquid substances can be redirected from one pipe system in another pipe system or in another pipe string.
    From DE-A 1 180 315 a diverter valve is known, in which the outlets to the side pipe stub are mutually closed by an adjustable flap. However, this does not form linear flow paths, and swirling occurs in the switch box. In addition, the flap is stored in bearings in the covers of the switch box, so that must be broken down to their removal of the switch box. Bearing and drive elements must be sealed to the housing.
    The invention has for its object to provide a Rohnweiche, with the quick switching is also possible as a simple way to easily remove the switch valve in case of failure or for cleaning purposes and to be able to use again.
    This object is achieved by the invention by a pipe switch with the features of the patent claim 1.
    The advantage of the pipe switch according to the invention lies in particular in that the butterfly valve sheet-shaped and arranged edgewise within the switch box and that the switch box between the pipe socket has a slot-shaped opening through which the switch flap can be inserted into the switch box, wherein a pivot axis of the Switch flap is mounted outside on the switch box. The pivot bearing is thus outside the flowpaths and thus protected from direct contact with the conveyed medium.
    This results in the following advantages in the pipe switch according to the invention: [0008] Simple installation and removal of the switch flap.
    - Attachment possibilities of switches and valves on the outside of the housing and
    Actuation by the damper drive.
    A preferred embodiment of the invention provides that the pivot axis of the flap is at least in the areas adjacent to the turnout opening cylind¬risch formed and that the edge contour of the switch box at the opening for receiving the pivot axis is rounded cylindrical section. The pivot axis seals the soft-mounting opening at the same time as soon as the switch flap is inserted.
    The preferred embodiment thus has the following additional advantages: Simple sealing of the switch installation opening and of the drive.
    Quick and easy replacement of the seal on the switch flap.
    In one possible embodiment of the invention, the overlapping areas of the pivot axis and / or the edge contour are covered at the opening with a sealing and sliding coating, for example made of PTFE. Alternatively it can be used between the pivot axis and the opening a sealing and sliding bearing element. In both cases, the bearing shell for the pivot axis forms at the same time a complete sealing of the switch installation opening.
    It is preferably provided that the pivot axis is at its two ends in each case comprises a bearing element which continues in a pawl which can be hooked to a bolt on the top or bottom of the switch box. This makes a very quick installation and removal of the switch flap possible. In addition, the lock also ensures a contact pressure and thus a good seal of the turnout opening.
    To drive the switch flap can be provided a linearly acting drive element which is pivotally mounted on a bearing point on the switch box and is connected via a Drehge¬lenk with an actuating lever which is connected to the pivot axis. It is thus easy to use a commercially available pneumatic cylinder.
    The invention will be explained in more detail with reference to the drawing. The figures show in detail: [0018] FIG. 1 a mounted diverter switch in perspective view from the outside; 2a, 2b, the pipe switch in section from above, each in different Montagesta¬ dien; FIG. 3 shows the area of the flap bearing in detail in perspective view; FIG. and [0021] FIGS. 4a-4e show the assembly of the flap on the diverter pipe shown in perspective, in various steps.
    Figure 1 shows a pipe switch 100, which consists essentially of a switch box 1 with three pipe sockets 3, 5, 7 and arranged within the switch box 1 points flap. From a main pipe socket 3, the flow path can be switched to one of the two secondary pipe sockets 4, 5 in the pipe switch 100.
    The pipe switch 100 according to the invention is designed for a robust and less prone to interference operation in harsh environment, to which according to the invention in particular the manner of mounting and mounting of the switch flap contributes, as will be explained below.
    For a robust design, all drive and switching elements are attached to the outside of the soft box 1, so that you do not come into contact with the conveyed material. At a bearing point 11.1 on the switch box 1 in the Ausführungsbei¬spiel designed as a pneumatic cylinder, linearly acting drive element 11 is pivotally arranged. At a rotary joint 12.1, the piston rod of the drive element 11 is connected to an actuating lever 12.2, which is connected in a form-fitting manner to a pivot axis 7 of the small flap 2.
    The actuating lever 12.2 runs behind the connection with the pivot axis 7 in a switching cam 12.3. The switching cam is shaped and dimensioned so that it acts in the Um¬schaltstellung the switch flap on an actuating element of a switching device 13, which is also arranged on the outside of the switch box 1. As a result, a safe changeover state can be signaled. If the switch flap can not be pivoted due to a blockage or not completely, the extension reaches 12.3 despite actuated An¬triebsvorrichtung 11, the switching device 13, whereby a control device, an error can be signaled.
    2a shows the Rohnweiche 100 in section from above, and immediately before the insertion of the switch valve. 2
    In the throat between the sockets 4, 5 a turnout opening 6ausausildet. Before that, a groove-shaped sliding bearing element 8 is set, which likewise contains a threaded installation opening for the passage of the switch flap 6. The switch flap 2 has at one end a pivot axis 7, which serves not only the storage and the drive of the switch flap 2, but at the same time also flush with the sliding bearing element 8anlegt and thus causes a seal on the edge of the turnout opening 6.
    Figure 2b also shows in sectional view from above the assembled state of the Rohr¬weiche 100. A flow path leads straight from the main pipe socket 3 through the switch box I through to the side pipe socket 4, provided that the switch valve in the Gestri¬chelt in Figure 2b is shown rest position. If the flow is to be directed to the side pipe socket 5, the switch valve 2 is switched to the working position, which is shown in Figure 2bwith solid lines. The material is now deflected. The connection to the secondary pipe socket 4 is also closed. The described flow paths can also be flowed through in reverse.
    The switch flap 2 is preferably made of a sandwich-like package of two metal sheets with an interposed, specially designed rubber gasket made of plastic with similar qualities and functions.
    The assembly of the diverter valve according to the invention is shown stepwise in Figures 4a to 4e, wherein the diverter 100 is shown in each case in perspective with a view of the Neben¬rohrstutzen 4, 5.
    In Figure 4a, only the switch box 1 is shown with the side-mounted drive element II and the pivot 12.1.
    Clearly visible is the slot-shaped gate installation opening 6 in the junction box 1 between the secondary pipe stub 4, 5 and the formation of the edge portion of the Weichenein¬bauöffnung, which is formed channel-shaped to receive a cylindrical member.
    If the switch flap 2 is removed, as shown in Figure 4a, the bearing is freely accessible and can be easily cleaned. The open switch installation opening 6 can be used, for example, to clean the interior of the switch box 1 with a jet of water.
    The distance between the side pipe stub 4, 5 and the between them eingeschlos¬sene angle are each chosen so that the area of the throat between the Nebenrohrstut¬zen 4, 5 is easily accessible at any time to remove the switch flap 2 or replace it again To be able to
    On top of the switch box, a bolt 1.1 is arranged, which is required for the attachment of bearing elements for the pivot axis 7 of the switch flap 2. A similar bolt is attached to the bottom.
    In Fig. 4b, a groove-shaped sliding bearing element 8 is set, which also contains a Weichcheneinbauöffnung. It thus extends along the edge contour recognizable in FIGS. 4a and 4b with two parallel lateral edges and arcuate edge regions at the lower and upper edge.
    In Figure 4c, the switch flap 2 is fully inserted into the switch box 1, so that from the outside only their end-side pivot axis 7 is visible. The pivot axis 7 is formed cylindrically at least in the contact region to the sliding bearing element 8, so that at the same time a sealing of the slot 6 is achieved by pivot axis 7 and slide bearing element 8 in interaction. On the pivot axis 7 a square is formed above to produce a positive connection with the operating lever 12.2.
    In Figure 4c, the bearing elements 7.1 are added to the top and bottom of the pivot axis 7, which are shown in Figure 3 in detail. The bearing elements 7.1 have an annular structure with a recess and an extension as a pawl, as can be seen in the enlargement of Figure 3. A bearing element 7.1 is pushed with its recess in each case to an end of the pivot axis 7. By a slight pivoting movement Verriege¬lung the pawl takes place on the bolt 1.1 on the switch box 1. This process is repeated at the other end of the pivot axis, on the underside of the switch box 1. Thereby, the bearing element 7.1 is pulled to the housing. It in turn is based on the shape of its recess at the rear of the pivot axis 7 and presses the pivot axis 7auf the sliding bearing element 8 and thus to the edge region of the switch installation opening. 6
    In Figure 4e, a switching device 13 is additionally attached. The operating lever is placed on the end of the pivot axis 7 and also connected to the pivot 12.1, whereby the transfer tube 100 is fully assembled.
    The dismantling takes place in the reverse order: After removing the Betäti¬gungshebels 12.1 need only the bearing elements 7.1 to be unlatched again to pull the switch flap 2 completely out of the switch box 1 can.
