Description

[0001] The present invention relates to a distributor device for a piping system, comprising a housing on which an inlet and at least two outlets are provided, wherein a rotatably mounted flap is provided in the housing, by means of which a flow path from the inlet can be opened selectively to the first outlet or the second outlet, wherein the flap is rotatably mounted on a shaft on which a drive lever arranged outside the housing is arranged in a rotationally fixed manner and which can be pivoted via an actuator.

[0002] EP 0 116 120 A1 discloses a pipe branch with a switching flap for conveying ground material from an inlet nozzle to an outlet nozzle or another outlet nozzle. A rotatable folding trough is provided for this purpose, which can be pivoted via a handle connected to a shaft. Such pipe branches can direct a volume flow to one or the other outlet. Instead of manually actuating a switching flap, it is also known to provide actuators for this purpose, which, for example, comprise a lifting cylinder and are linearly adjustable.Until now, the adjustment of the actuator's movement to the pivoting path of a changeover flap was achieved by individually adjusting the changeover lever, ensuring that the changeover flap rests precisely against a valve seat of a distributor housing in its end positions. Incorrect positions of the changeover flap lead to leaks or excessive contact pressure on a seal, resulting in increased wear. The corresponding adjustment work on the lever, which usually consists of welded individual parts, is therefore considerable.

[0003] It is therefore an object of the present invention to provide a distribution device which allows simple adjustment of the flap and is easy to assemble.

[0004] This object is achieved with a distribution device having the features of claim 1.

[0005] The distribution device according to the invention comprises a drive lever for pivoting the flap, which is formed from several relatively adjustable parts in order to adjust a pivoting movement of the flap upon a predetermined movement of an actuator. The use of such an adjustment mechanism for the drive lever has the advantage that no adjustment work is required during assembly of the distribution device; in particular, no individual parts need to be welded together. Rather, the drive lever can be assembled from several individual parts into a single unit, which can then also be subsequently adjusted on site.

[0006] Preferably, the drive lever has at least three parts that are adjustable relative to one another, in particular a part coupled to the actuator, a part coupled to the shaft, and a connecting part arranged between these parts. The three parts are then adjustable relative to one another, so that, in particular, the length of the drive lever and the angular position relative to the shaft can be adjusted.

[0007] The drive lever preferably comprises a part that is non-rotatably connected to the shaft, on which a connecting part is held so as to be adjustable in the direction of rotation. Preferably, the connecting part is continuously adjustable in the direction of rotation relative to the shaft, for example, within an angular range between 3° and 20°. The connecting part can be designed to be adjustable from an initial position in opposite directions.

[0008] In a further embodiment, the drive lever is continuously adjustable in length. The drive lever can comprise an angled part that is connected to the connecting part on one side and to the actuator on the other side. An elongated guide can be provided on the connecting part, extending substantially radially to the shaft, in order to secure the angled part in different positions to the connecting part by clamping or other fastening means.

[0009] The rotational position can be adjusted via the connecting part, which has a receptacle with an adjustable stop, preferably two adjustable stops, which engage around a projection provided on the part connected to the shaft in a rotationally fixed manner. This allows the orientation of the connecting part in the direction of rotation to be changed in both directions.

[0010] The invention will be explained in more detail below using an exemplary embodiment with reference to the accompanying drawings. Fig. 1 a view of a distribution device according to the invention for a pipeline system; Fig. 2A to 2C several views of a drive lever of the distribution device of the Fig. 1; Fig. 3 a detailed view of the drive lever of the Fig. 2, and Fig. 4 a view of a modified angular part for a drive lever.

[0011] A distribution device 1 comprises a housing 2 that forms a flow channel and has an inlet 3 and two outlets 4 and 5. The inlet 3 and the outlets 4 and 5 can be designed as tubular nozzles to which pipes of a pipeline system are connected and through which a conveyed material, for example a bulk material, can flow. A flap 15 is pivotably mounted in the housing 2. On an outer edge, at least in some regions, optionally also circumferentially, the flap 15 has a seal 6 that can be placed against a valve seat or a sealing edge 7 or 8 within the housing 2 in order to guide a conveyed material flowing into the inlet 3 selectively to the outlet 4 or the outlet 5.

[0012] The essentially plate-shaped flap 15 is coupled in a rotationally fixed manner to a shaft 9, which extends through the housing 2 to an outer side and is connected outside the housing 2 to a drive lever 10. The drive lever 10 can be pivoted via an actuator 12, wherein the actuator 12 is variable in length for this purpose and is designed, for example, as a lifting cylinder or electromechanical actuating unit. The actuator 12 is connected to the drive lever 10 via a connecting element 14, for example a bolt, and on the opposite side via a connecting element 13 to a holder 11, which is fixed, for example, to the housing 2. The holder 11 can also engage around the shaft 9, wherein the actuator 12, the drive lever 10 and the holder 11 form a force triangle in order to move the flap 15 from the position shown in FIG. 1 when the length of the actuator 12 is changed. Fig. 1 left position, for example, into the position shown as flap 15'.

[0013] The drive lever 10 is in the Fig. 2A to 2C. The drive lever 10 comprises a part 16 which is connected to the shaft 9 in a rotationally fixed manner and has a receptacle 29 having two radial grooves 17 into which a projection or a wedge on the shaft 9 can be inserted in order to establish a rotationally fixed connection between the part 16 and the shaft 9. Other fastening means for establishing a rotationally fixed connection, for example clamping elements or positive locking means, can also be used.

[0014] The part connected to the shaft 9 in a rotationally fixed manner comprises a radially projecting projection 18 which engages in a receptacle 19 of a connecting part 20, as can also be seen in the enlarged illustration of the Fig. 3 is visible. The connecting part 20 comprises an adjustment mechanism on the receptacle 19 in order to be able to adjust the angular position of the connecting part 20 relative to the part 16. On opposite sides, a threaded bolt 25 is provided for this purpose, which engages through an internal thread on the connecting part 20 and can be clamped to the connecting part 20 via a nut 26. The threaded bolt 25 forms a stop 28 for the projection 18 at its front end, so that in order to adjust the angular position of the connecting part 20 relative to the shaft 9, the nut 26 is first loosened in order to then turn the threaded bolt 25 via the head 27 into the desired position and then secure this position via the nut 26. The threaded bolt 25 can then be adjusted accordingly on the opposite side so that the connecting part 20 is now aligned at a different angle to the shaft 9.The adjustment range α between the connecting part 20 and the part 15 can, for example, be in a range between 3° and 20°, in particular 6° to 15°.

[0015] The connecting part 20 comprises an elongated guide 23, which is designed as a recess and includes an elongated slot 24 through which fastening means in the form of screws 32 pass. A web 31 of an angular part 30 can be secured to the connecting part 20 via the screws 32. The angular part 23 can be moved along the guide 23 and then fixed in the desired position. This allows the radial length of the drive lever 10 to be adjusted.

[0016] The angular part 30 comprises a second web 33, on which an opening 34 is provided for the passage of the connecting element 14 in order to couple the angular part 30 to the actuator 12.

[0017] The drive lever 10 thus comprises three parts that can be adjusted relative to one another, namely the part 16 connected to the shaft 9, the connecting part 20 that can be rotated relative to the part 16, and the angular part 30 that can be adjusted radially to the connecting part 20 and can optionally also be non-angular. This allows both the length of the drive lever 10 and its orientation in the direction of rotation to be adjusted retrospectively, for example if the flap 15 and the seal 6 are subject to a certain amount of wear and therefore require readjustment. In addition, the pivoting path of the flap 15 and the contact with the valve seats 7 and 8 can be optimized by appropriate adjustment.

[0018] In Fig.4 shows a modified angular part 30' that is longer than the angular part 30. The web 31' can be inserted into the guide 23 and fixed in the desired position via screws 32 that extend through the openings 32'. The angular part 30' further comprises a second leg 33', on which an opening 34' is provided for coupling to the actuator 12. This allows adaptation to different sizes of distribution devices 1 by exchanging the angular part 30 or 30'.

[0019] The adjustment mechanisms for rotational adjustment and length adjustment shown in the illustrated embodiment can also be designed differently, preferably using stepless adjustment devices that enable fine adjustment.
