An apparatus comprising: a valve unit, an actuator, and a mounting module, wherein the actuator is capable of establishing an operational connection with the valve unit, and the mounting module and the actuator together form a separate unit capable of being connected to the valve unit.

Description

[0001] The subject of this invention relates to an apparatus comprising a valve unit and an actuator, wherein the actuator is capable of establishing an operational connection with the valve unit.

[0002] These devices are specifically designed for milking animals, particularly cows, sheep, goats, llamas, and other dairy-producing animals.

[0003] The milking equipment includes multiple milking stations. Each milking station is equipped with a milking device having a milking cup assembly with at least one milking cup. The milking cup is designed to attach to the teat of a dairy animal and to drain milk from it. The milking cup includes a milking cup sleeve into which a resiliently deformable teat liner is inserted. The term "teat liner" is used synonymously here. The teat liner may also be made of other elastic materials. Teat liners made of silicone rubber are particularly hygienic.

[0004] The milking cup can optionally be connected to the milk collector via a short milk tube. The outlet fluid of the milk collector is connected to the milking line system.

[0005] As raw milk is a crucial starting point for the food and food industry, it must meet domestic and international quality requirements to protect consumers and industrial processing capacity. Therefore, relevant national or international regulations must be followed. Maintaining predetermined hygiene standards is also essential to ensuring high-quality milk. Consequently, the components of milking equipment must be cleaned. Cleaning can be performed using fluids, particularly water, with or without cleaning, sterilizing, or other additives.

[0006] In this situation, it is essential to prevent the milk to be processed from being contaminated by the cleaning fluid. For this purpose, a device equipped with a valve is used. Such valves are also known as safety valves.

[0007] These valves are specifically designed to ensure that unusable milk, such as milk from sick cows, does not enter the usable milk.

[0008] A safety valve or valve is preferably understood to refer to a valve unit having a housing with a housing body having channels for inlet and outlet, and a housing cover detachably connected to the housing. The valve unit has a movable piston that closes or opens the channels depending on its position. The piston has a piston shaft extending through a seal and the housing cover. The seal is preferably a diaphragm seal disposed between the housing cover and the housing body. The seal may also be a shaft seal.

[0009] Because a very high level of safety must be maintained, especially in milking equipment, it is known that at least the seals on the pistons, particularly the diaphragm seals, must be replaced periodically. Solutions known to date that prioritize safety have relatively complex structures.

[0010] From this perspective, the present invention is based on the purpose of illustrating a device that meets a high level of security but is associated with a low degree of complexity.

[0011] This objective is achieved by means of the means claimed in the independent claim. Further advantageous configurations are the subject of the dependent claims.

[0012] The device according to the invention includes a valve unit, an actuator, and a mounting module. The actuator is capable of establishing an operational connection with the valve unit. The actuator is preferably an electrically actuated, pneumatic, or electronically actuated actuator. For example, the actuator may be a pneumatic actuator having a cylinder-piston unit. The piston is connected to a rod that cooperates with the valve unit. Depending on the position of the piston of the actuator, the valve unit is opened or closed, thereby opening a fluid connection or passage within the valve unit.

[0013] The device according to the invention has a mounting module. The mounting module and the actuator together form a separate structural unit. This separate structural unit can be detachably connected to the valve unit.

[0014] The complexity of the device is reduced due to the invention. The mounting module allows the mounting module itself to be connected to and disconnected from the valve unit via an actuator. This also includes, in turn, the valve unit being released as a separate unit when the connection between the valve unit and the mounting module is released. This design configuration reduces the complexity of the device. In particular, this design configuration creates the possibility of performing maintenance work on the valve unit more easily. If the mounting module and the valve unit are separated, access to these parts of the valve unit can be simplified, for example, if the valve unit is a valve with a diaphragm seal and a piston. This also means that the time required to replace the diaphragm seal, and possibly a diaphragm seal with a piston, can be reduced.

[0015] A further advantage of the present invention is that, in the event of a malfunction of the actuator, the mounting module containing the actuator can be replaced.

[0016] The mounting module and valve unit are geometrically matched, allowing the mounting module to be connected to the valve unit in a specified, predefined position. The connection between the valve unit and the mounting module is preferably a form-fit connection. It can be specifically configured as a snap-fit ​​connection. The mounting module has suitable snap-fit ​​protrusions for this purpose, which engage with correspondingly designed stops on the valve unit.

[0017] A particularly preferred configuration of the device is as follows: the valve unit housing has a first nozzle forming an inlet and a second nozzle forming an outlet. The mounting module has two lugs formed parallel to each other, each lug having an opening such that one lug engages around the first nozzle and the second lug engages around the second nozzle. In this arrangement, the housing is positioned between the lugs. This configuration of the mounting module enables positioning of the mounting module relative to the valve. The mounting module may also have a stop, thereby achieving spatial positioning of the mounting module relative to the valve unit.

[0018] The actuator has a drive element connected to a piston of the valve unit. This is a form-fit connection, preferably configured such that the drive element has a notch extending along the axial direction of the piston, into which the piston shaft can be inserted. The mounting direction is transverse to or perpendicular to the axial direction of the piston.

[0019] Furthermore, the drive element preferably has two slots provided perpendicular to the axial direction of the piston, parallel to each other, and spaced apart. The piston shaft has a corresponding radially outward-pointing disc that is introduced into the slot.

[0020] In this way, upward and downward movement is achieved during the vertical displacement of the piston.

[0021] According to the concept of the invention, the following variation is first realized: wherein the mounting module is fastened in a fixed position to a support structure or wall, for example. To replace the diaphragm seal and (if necessary) to replace further seals located in the valve unit, the valve unit is detached from the pipeline to which it is connected. Alternatively, if the valve unit is fixedly connected to the emulsion transport pipeline, the possibility of detaching the mounting module from the valve unit is provided.

[0022] If the diaphragm seal is replaced and (if necessary) further seals are added, the valve unit can be reconnected to the pipeline, where alignment of the valve unit is facilitated by the fact that the mounting module is stationary.

[0023] If it is not possible to secure the mounting module statically (e.g., to a support structure or wall), the mounting module is detached from the valve unit to allow replacement of the valve unit's diaphragm seal and, if necessary, further seals. The valve unit remains connected to the pipeline. After replacement of the diaphragm seal and, if necessary, further seals, the mounting module, forming a separate structural unit with the actuator, can then be connected to the valve unit.

[0024] In the field of milking technology, so-called shut-off-drain-shut-off valves are also used. Such shut-off-drain-shut-off valves are specified, for example, by the US FDI guidelines for the field of milking technology. For example, such shut-off-drain-shut-off valves are known from DE 10 2019 128 235 A1. These valve units have a shut-off valve with an outlet connected to the inlet of a second shut-off valve. These valves are connected in series. Between these valves, a drain outlet is provided via a drain valve.

[0025] The opening and closing sequence of the individual valves is crucial in this type of shut-off-drain-shut-off valve. It is also necessary to replace the seals for all three valves. If such an arrangement of valve units with shut-off-drain-shut-off valves is provided, the mounting module has actuators suitable for and designed to actuate the individual valves. The mounting module preferably has a top component operatively connected to the actuator. Each shut-off valve has a piston rod. The top component has a U-shaped configuration, with a spring in each free leg of the U-shaped top component, the spring engaging with the corresponding piston rod of the valve. The spring force is selected in such a way that, depending on the movement of the top component, one valve closes first, then the second valve. A bridging element overcomes the spring force displacement.

[0026] The mounting module is preferably designed to have a support that engages with the underside of the valve unit. The mounting module preferably has a pivotable bracket that can be connected to the valve unit in a form-fit manner.

[0027] The valve unit of a milking apparatus for milking dairy animals according to the present invention comprises a first valve having an inlet nozzle and a second valve having an outlet nozzle. The outlet of the first valve and the inlet of the second valve form a passage. The valve unit also includes a discharge valve having a reciprocating valve body. In the closed position, the valve body of the discharge valve closes, connecting the passage to a free space passage. In the open position, the valve body of the discharge valve opens the passage. This free space is fluidly connected to at least one port.

[0028] According to a further aspect of the invention, the valve unit includes a first valve having an inlet nozzle and a second valve having an outlet nozzle. The outlet of the first valve and the inlet of the second valve form a passage. The valve unit also includes a drain valve having a reciprocating valve body. In the closed position, the valve body of the drain valve closes, connecting the passage to a free space passage. In the open position, the valve body of the drain valve opens the passage. This free space is fluidly connected to at least one port.

[0029] This configuration of the valve unit according to the invention creates the possibility of cleaning the passage connecting the first and second valves to each other. Cleaning fluid can flow into the free space of the discharge valve and from there out through the at least one port into the passage. This achieves passage cleaning. It is possible that fluid present in the passage, as well as fluid introduced into the free space, can also be extracted through this one port. If needed, a suitable ventilation system is available through which fluid flows away or out. A configuration in which two ports are provided for fluid connection to the free space is particularly preferred. The ports are preferably arranged opposite each other, so that fluid inlet is formed via one port and fluid outlet is formed via the other port.

[0030] Free space should be understood as a space within which free flow can occur, particularly when the drain valve is in the open position. Free space can be formed, for example, by creating a groove in the inner side surface of the drain valve, thus forming a space to accommodate the valve body. To simplify design and reduce technical costs in implementing the drain valve, especially when the drain valve is made of plastic, it is recommended that the cross-section of the free space be annular. This includes a valve body with a circular cross-section, at least when viewed in a cross-section along the axial direction of the valve body. The valve body can be designed, for example, in the form of a truncated cone, such that when in the closed position, the edges of the truncated cone-shaped valve body close the passageway. The space in which the valve body resides preferably has a circular cross-section.

[0031] The passage has a valve seat that interacts with the valve body. The valve body may have a seal disposed on and detachably connected to the latter. This simplifies the replacement of the seal. To meet hygienic requirements, this operation must be performed at predetermined time intervals. The seal is preferably an O-ring seal. In the closed position, the O-ring seal rests on the valve seat.

[0032] Based on a further optimized configuration of the valve unit, it is recommended that the valve body have a seal that seals the free space relative to the environment. This specifically ensures that in the event of leakage from the drain valve relative to the passage, fluid flows into the environment. There is also the possibility of cleaning the free space in the closed position of the drain valve.

[0033] The valve unit preferably includes a first valve with an inlet nozzle, a second valve with an outlet nozzle, an outlet of the first valve and an inlet of the second valve forming a passage, and a discharge valve with a valve body that can move back and forth and close the passage connecting the passage to a free space in a closed position, and open the passage in an open position, the free space being fluidly connected to at least one port.

[0034] The cross-section of the free space is preferably annular.

[0035] It is particularly recommended that the passage have a valve seat that interacts with the valve body. The valve body preferably has a sealing element that abuts against the valve seat in the closed position. A configuration in which the valve body has a seal that seals the free space from the surrounding environment is particularly preferred.

[0036] The discharge valve is preferably designed such that, when in the open position, the valve body releases free space toward the atmosphere.

[0037] The valve unit is preferably designed such that free space fluid is connected to two ports arranged opposite to each other.

[0066] Figure 26 Shown in perspective according to Figure 25 The actuation unit.

[0067] Figure 1 The device 1 is shown in perspective. The device 1 includes a valve unit 2, an actuator 3, and a mounting module 4.

[0068] Valve unit 2 has a housing body 5. Housing body 5 has an inlet nozzle 6 and an outlet nozzle 7. The inlet nozzle 6 is detachably connected to a portion 9a of the emulsion transport line via a clamping connection 8a. The outlet nozzle 7 is connected to a portion 9b of the emulsion transport line by means of a detachable clamping connection 8b.

[0069] The housing cover 10 is detachably connected to the housing body 5. The housing cover 10 has a cap-shaped design. In this case, the preferred configuration is that the connection between the housing body 5 and the housing cover 10 is a releasable screw connection.

[0070] Mounting module 4 has a mounting plate 15. In the illustrated exemplary embodiment, mounting plate 15 has openings 16a, 16b, by means of which mounting plate 15 can be secured to a support structure (not shown). Mounting plate 15 has a carrier 17, on which actuator 3 is fastened. Guide member 19 is provided on the side of carrier 17 opposite to actuator 3. Guide member 19 has two lugs 19a, 19b arranged at intervals from each other. Drive member 14 is guided between lugs 19a, 19b of guide member 19. Drive member 14 is connected to actuator 3 via a connecting member 20 extending through a channel opening 18 in carrier 17.

[0071] The actuator 3 is preferably configured as a piston-cylinder unit. It is more preferably a pneumatic piston-cylinder unit. The actuator 3 is connected to a controller (not shown), thereby enabling the actuator 3 to be activated and deactivated according to a control signal.

[0072] The actuator 3 and the mounting module 4 together form a separate structural unit that is releasably connected to the valve unit 2 in a form-fitting manner.

[0073] Figure 4 The cross-sectional view shows the results according to Figure 1 Device 1. The housing body 5 has external threads 26. A slip nut 25 is screwed into the external threads 26 through the edge, thereby securing the housing cover 10 to the housing body 5 when the diaphragm seal 13 is inserted.

[0074] From the basis Figure 4 As can be seen from the cross-sectional diagram, valve unit 2 is formed by a valve having a moving piston 12. The moving piston 12 of valve unit 2 has a piston shaft 11. The piston shaft 11 is formed in two parts. It has a first part 11.1 and a second part 11.2. The first part 11.1 and the second part 11.2 of the piston shaft are detachably connected to each other. This connection is preferably a form-fit and / or force-fit connection, especially a threaded connection.

[0075] Piston shaft 11 extends through diaphragm seal 13. Diaphragm seal 13 is formed with a first portion 11.1 and a second portion 11.2 of piston shaft such that diaphragm seal 13 is disposed between and secured to the first portion 11.1 and the second portion 11.2 of piston shaft. Diaphragm seal 13 has a circumferential edge region formed in the form of a bead, which is positioned in a sealing manner between housing body 5 and housing cover 10.

[0076] The movable piston 12 has a closure 12.1 at one end, by means of which the outlet 12.2 of the valve unit 2 can be opened and closed.

[0077] exist Figure 4 In the illustrated operating position, the outlet 12.2 of valve unit 2 is closed by the sealing body 12.1, thereby eliminating fluid connection between the inlet nozzle 6 and the outlet nozzle 7. The moving piston 12 can be moved to the open position by means of the actuator 3, thereby establishing fluid connection between the inlet nozzle 6 and the outlet nozzle 7.

[0078] The second portion 11.2 of the piston shaft 12 extends through the housing cover 10 and is detachably connected to the drive member 14. Specifically, from... Figure 4 It can be seen that the connecting member 20 and the piston shaft 11 are located on a common axis. The second part 11.2 of the piston shaft 11 has two radially outwardly pointing ribs 21a and 21b spaced apart from each other. The ribs 21a and 21b are preferably annular. The drive member 14 has corresponding grooves 22a and 22b that are adapted to the contours of the ribs 21a and 21b. As a result, the drive member 14 is connected to the piston 12 of the valve unit 2 in a form-fit manner.

[0079] Specifically, it can be seen from Figure 5 The mounting module 4 is shown in the image. The mounting module and the valve unit are geometrically matched, allowing them to be connected to a specified, predefined location. The connection between the valve unit and the mounting module is preferably a form-fit connection. It can be specifically configured as a snap-fit ​​connection. The mounting module preferably has suitable snap-fit ​​protrusions that engage with correspondingly designed stops on the valve unit, and vice versa.

[0080] In a preferred exemplary embodiment, the mounting module 4 has two lugs 23a and 23b spaced apart from each other. Each lug 23a and 23b has a groove 24a and 24b, respectively. In the mounted state, i.e., with the valve unit 2 connected to the mounting module 4, the edge of the groove 24a partially engages around the inlet nozzle 6. The edge of the groove 24b partially engages around the outlet nozzle 7. The grooves 24a and 24b also form stop surfaces for positioning the mounting module. The figure also shows a web 27, which is part of the mounting module 4. The web 27 preferably has a spring-loaded design. In the mounted state, the free end region of the web 27 abuts against the housing body 10 of the valve unit 2. The web 27 is preferably connected to the valve unit 2 by a snap-fit ​​mechanism.

[0081] Figures 1 to 4 The device is shown in its installed state, meaning that valve unit 2 is connected to the emulsion line 9. Furthermore, valve unit 2 is operatively connected to actuator 3, which forms a separate structural unit with mounting module 4.

[0082] Figure 5 A perspective view shows portions 9a and 9b of the device 1 and the emulsion transport line, wherein the device 1 is not connected to the emulsion transport line.

[0083] A valve unit 2, comprising a housing body 5 with an inlet nozzle 6 and an outlet nozzle 7, is arranged between the ends of portions 9a and 9b of the emulsion transport pipeline. The valve unit 2 is fluid- and airtightly connected to portions 9a and 9b of the emulsion transport pipeline via clamping connections 8a and 8b. Arrow A indicates the mounting direction of the mounting module 4, on which an actuator 3 is mounted.

[0084] During installation, lug 23a engages around a portion of the inlet nozzle 6. Lug 23b engages around a portion of the outlet nozzle 7. Ribs 21a and 21b of the piston shaft 11 (which point radially outward relative to each other) slide into recesses 22a and 22b. Actuator 3 is form-fitted to piston 12 of valve unit 2.

[0085] Figure 4 The operation position of valve unit 2 closed is shown, thus eliminating fluid connection between inlet nozzle 5 and outlet nozzle 7. By activating actuator 3, piston 12, connected to actuator 3 via shaft 15, drive member 14, and connecting member 20, can be moved to an operation position that establishes fluid connection between inlet nozzle 5 and outlet nozzle 7.

[0086] The mounting module allows for connection and disconnection from the valve unit. If the valve unit is fixed to the emulsion delivery line, the mounting module is detached from the valve unit as a separate unit.

[0087] Figure 6 and Figure 7 An embodiment where the diaphragm seal 13 is preferably replaced is shown. For this purpose, the mounting module 4 is detached from the valve unit 2. In this variant, the valve unit 2 remains connected to the emulsion delivery line with portions 9a, 9b. The housing cover 6 can be removed by releasing the connection between the housing body 5 and the housing cover 6. The housing body 5 has external threads 26. A slip nut 25 is screwed into the external threads 26 via its edge, thereby securing the housing cover 10 to the housing body 5 with the diaphragm seal 13 inserted. The housing cover 10 can be detached from the housing body 5 by loosening the slip nut 25. The first portion 11.1 and the second portion 11.2 of the piston shaft 11 are separated from each other. The diaphragm seal 13 is then released and can be replaced by another diaphragm seal. If the piston 12 has a seal, it can be replaced if necessary.

[0088] The mounting module allows the valve unit to be connected to and disconnected from the mounting module. If the mounting module is secured to the structure, the valve unit can be detached from the emulsion delivery line portion and from the mounting module by releasing the clamping connection.

[0089] The preferred configuration of the piston shaft 11 and the drive element 14 allows the piston shaft 11 to be separated from the drive element 14. The installation or removal direction of the valve unit extends substantially perpendicular to the longitudinal axis of the piston rod 11 and the drive element 14.

[0090] Assembly is performed in reverse order. The position of valve unit 2 is also defined by recesses 24a and 24b. During installation, the drive members 21a and 21b of piston shaft 11 slide into drive member 14.

[0091] Due to the device's design configuration, its complexity is reduced. In particular, this design configuration creates the possibility of performing maintenance work on the valve unit more easily. If the valve unit and mounting module are separated, seal replacement can be simplified. This also means that maintenance time, such as replacing diaphragm seals and possibly diaphragm seals with pistons, can be reduced. A further advantage is that, in the event of a failure of the actuator included in the actuation unit, the mounting module containing the actuator can be replaced.

[0092] Figures 8 to 13 A further configuration of the device according to the invention is shown.

[0093] Figure 8 A perspective view of a milking apparatus 1 with valve unit 2 for milking dairy animals is shown. Valve unit 2 includes a first valve 30. The first valve 30 has an inlet nozzle 31, which is connected to a portion 9a of an emulsion transport line via a clamping connection 8a. A second valve 50 is provided. The second valve 50 has an outlet nozzle 51, which is connected to a portion 9b of the emulsion transport line via a clamping connection 8b.

[0094] Valve unit 2 with first valve 30 and second valve 50 in Figure 9 and Figure 10 The image is shown in the middle. Figure 9 The first valve 30 and the second valve 50 are shown in an assembled state. In the illustrated embodiment, the first valve 30 and the second valve 50 are connected to each other via a housing component 70.

[0095] The first valve 30 includes a housing 32. In a preferred exemplary embodiment, the housing 32 of the first valve 30 is formed of a plurality of components. The housing 32 has a housing body 33. The housing body 33 has an inlet nozzle 31. The housing body 33 is detachably connected to a housing cover 34. A first piston shaft 35 extends out of the housing cover 34.

[0096] The second valve 50 is also configured in a similar manner. The second valve 50 has an outlet nozzle 51 formed on the housing body 53 of the housing 52. The housing body 53 is detachably connected to the housing cover 54. The second piston shaft 55 of the second valve 50 extends through the housing cover 54. The outlet nozzle 51 is connected to a portion 9b of the emulsion transport line via a clamping connection 8b.

[0097] The housing covers 34 and 54 can be configured as separate components. They are preferably able to form a single structural unit.

[0098] A radially outward flange 36 is provided on the side surface of the housing cover 34. A slip nut 37 engages around the housing cover 34. The second valve 50 also has a radially outward flange 56 on its housing cover 54. A slip nut 57 engages around the housing cover 54.

[0099] The housing body 33 has a threaded portion 38 adjacent to the housing cover 34. The housing body 53 of the second valve 50 has a threaded portion 58 adjacent to the housing cover 54.

[0100] A housing component 70 is provided, comprising a housing body 33 connected to the first valve 30 and a housing body 54 connected to the second valve 50. The housing component 70 has a drain valve. The valve body 76 of the drain valve is accessible from... Figure 10 I saw it in the middle.

[0101] Figure 11 The cross-sectional diagram shows the results according to Figure 8 Device 1. From according to Figure 11As can be seen from the cross-sectional view, the first valve 30 has a first moving piston 39. The first moving piston 39 of the first valve 30 has a first piston shaft 35. The first piston shaft 35 is formed in two parts. It has a first portion 35.1 of the piston shaft and a second portion 35.2 of the piston shaft. The first portion 35.1 and the second portion 35.2 of the piston shaft are detachably connected to each other. This connection is preferably a form-fit and / or force-fit connection, especially a screw connection. The first piston shaft 35 extends through a diaphragm seal 44. The diaphragm seal 44 is formed with the first portion 35.1 and the second portion 35.2 of the piston shaft such that the diaphragm seal 44 is arranged between the first portion 35.1 and the second portion 35.2 of the piston shaft and thereby fixed to the first piston shaft 35. The diaphragm seal 44 has a circumferential edge region formed in the form of a bead, which is positioned in a sealing manner between the housing body 33 and the valve cover 34.

[0102] The first moving piston 39 has a closure 40 at one end, by means of which the outlet 41 of the first valve 30 can be opened and closed.

[0103] exist Figure 11 In the illustrated operating position, the outlet 41 of the first valve 30 is closed by the sealing body 40, thereby eliminating fluid connection between the inlet nozzle 31 and the outlet 41. The first moving piston 39 can be moved to the open position, thereby creating fluid connection between the inlet nozzle 31 and the outlet 41.

[0104] Figure 11 The second valve 50 is shown to have a second moving piston 59. The second moving piston 59 has a second piston shaft 55, which comprises two parts: a first part 55.1 and a second part 55.2. Shaft parts 55.1 and 55.2 are detachably connected to each other. Shaft parts 55.1 and 55.2 are preferably screwed together. The second moving piston 59 has a closing body 60. The closing body 60 of the second valve 50, according to… Figure 11 In the diagram, the inlet 51 is closed, so that there is no fluid connection between the inlet 61 and the outlet nozzle 51.

[0105] The second piston shaft 55 extends through the diaphragm seal 54. The diaphragm seal 54 is formed with the first portion 55.1 and the second portion 55.2 of the piston shaft such that the diaphragm seal 54 is disposed between the first portion 55.1 and the second portion 55.2 of the piston shaft and thereby fixed to the second piston shaft 55. The diaphragm seal 54 has a circumferential edge region formed in the form of a bead, which is positioned in a sealing manner between the housing body 53 and the housing cover 54.

[0106] The housing component 70 has a channel 71 that connects the outlet 41 of the first valve 30 to the inlet 61 of the second valve 50. The channel 70 can be accessed by means of… Figure 11 The discharge valve 75 shown in the diagram is either closed or open.

[0107] The discharge valve 75 has a valve body 76. The valve body 76 is connected to an actuation unit, which enables the valve body 76 to move from an open position to a closed position and vice versa. Figure 11 The open position of valve body 76 is shown. The cross-section of valve body 76 is substantially circular.

[0108] If the discharge valve 75 is in the open position, this means that the fluid in passage 71 is connected to the ambient atmosphere, and the first valve 30 and the second valve 50 are closed. In this operating position of these valves, fluid in the passage, particularly milk, can flow out of passage 71.

[0109] The first valve 30, the second valve 50, and the discharge valve 75 form a valve unit also known under the name "block-discharge-block". Figure 11 As shown, the first valve 30 and the second valve 50 are closed, meaning that these valves 30 and 50 are in the blocking position. The discharge valve 75 is in the open position, meaning that it is in the discharge position.

[0110] Figures 8 to 13 A valve unit 2 is shown, comprising a first valve 30, a second valve 50, and a discharge valve 75, and incorporating a mounting module 4. In a preferred exemplary embodiment, the mounting module 4 has an actuator 3. The actuator 3 actuates the first valve 30, the second valve 50, and the discharge valve 75 via an actuation unit 80. The mounting module 4 with the actuation unit 80 forms a structural unit. The valve unit and this structural unit together form the device.

[0111] Valve unit 2 is preferably in the form of a shut-off-discharge-shut-off valve unit. Valve unit 2 can be switched such that, in a first position, both the first valve 30 and the second valve 50 are open and the discharge valve 75 is closed. In a second position, which can also be referred to as the shut-off position, the first valve 30 and the second valve 50 are closed and the discharge valve 75 is open.

[0112] The actuator 3 is preferably formed as a piston-cylinder unit. This is particularly a pneumatic piston-cylinder unit, the ports of which are not shown. The actuator 3 is connected to a controller (not shown), thereby enabling the actuator 3 to be activated and deactivated according to a control signal. The actuator 3 is fixed to the mounting plate 15 in a stationary manner.

[0113] The actuation unit 80 includes a top component 81. The top component 81 has a first leg 81.1 and a second leg 81.2, which are connected to each other via a support plate 81.3. The top component 81 is preferably formed as a single piece. The support plate 81.3 has a through opening through which the rod 43 of the actuator 3 extends. Figure 11 The display rod 45 has a flange 46, on which the support plate 81.3 rests.

[0114] The retainer 82 is connected to the mounting plate 15. The retainer 82 includes two claw-shaped lugs 83.1, 83.2 that partially engage around the first and second legs 81.1, 81.2. The lugs 83.1, 83.2 and the legs 81.1, 81.2 are designed such that the top member 80 can slide within the retainer 82 in the longitudinal direction of the lugs 83.1, 83.2.

[0115] The first leg 81.1 of the top component 81 has a first groove 84.1 extending in the longitudinal direction of the first leg 81.1 and extending over a portion of the longitudinal range of the first leg 81.1 from its free end. A first abutment 85.1, pointing radially inward toward the first groove 84.1, is provided at the free end of the first leg 81.1. The first groove 84.1 extends in the longitudinal direction of the first leg 81.1 into a first threaded hole 86.1. A first adjusting screw 87.1 is screwed into the first threaded hole 86.1.

[0116] The second leg 81.2 of the top component 81 has a second groove 84.2 that extends in the longitudinal direction of the second leg 81.2 and extends over a portion of the longitudinal range of the second leg 81.2 from its free end. A second abutment 85.2 is provided at the free end of the second leg 81.2, pointing radially inward toward the second groove 84.2. The second groove 84.2 merges into a second threaded hole 86.2 in the longitudinal direction of the second leg 81.2. A second adjusting screw 87.2 is screwed into the second threaded hole 86.2.

[0117] The first groove 84.1 is open toward the first piston shaft 35 of the first valve 30, allowing the first piston shaft 35 to be introduced into the first groove 84.2. In the installed state, as... Figure 8 and Figure 9As shown, the second portion 35.2 of the piston shaft of the first piston shaft 35 of the first valve 30 extends into the first groove 84.1. The second portion 35.2 of the piston shaft of the first piston shaft 35 has a first rib 65 pointing radially outward. The first rib 65.1 is preferably annular. The shape of the rib 65.1 is adapted to the internal contour of the first groove 84.1. In the installed state, the first rib 65.1 preferably rests on the first abutment 85.1. A first spring element 88.1, particularly a compression spring, is preferably provided between the free end region of the first piston shaft 35 and the first adjusting screw 87.1.

[0118] The second groove 84.2 is open toward the second piston shaft 55 of the second valve 50, allowing the second piston shaft 55 to be introduced into the second groove 84.2. In the installed state, as... Figure 8 and Figure 9 As shown, the second piston shaft 55, particularly the second portion 55.2 of the piston shaft of the second valve 50, extends into the second groove 84.2. The second portion 55.2 of the piston shaft of the second piston shaft 55 has a radially outwardly pointing second rib 65. The second rib 65.2 is preferably annular. The shape of the second rib 65 is adapted to the internal contour of the second groove 84.2. In the installed state, from... Figure 8 or Figure 9 It can be seen that the second rib 65 rests on the second abutment 81.2. Preferably, a second spring element 88.2, particularly a compression spring, is provided between the free end region of the second piston shaft 55 and the second adjusting screw 87.2.

[0119] The actuation unit has a transmission element 90. The discharge valve 75 of valve unit 1 is actuated by means of the transmission element 90. The transmission element 90 is preferably U-shaped. It has first and second legs 91.1 and 91.2 that are spaced apart from each other and parallel to each other. The legs 91.1 and 91.2 are connected to each other via a base 91.3. The first leg 91.1 is indirectly connected to the actuator 3. This indirect connection is preferably generated by a spring element. Particularly preferably, a compression spring 92 is provided, which is supported on the support plate 81.3 and applies a compressive force to the first leg 91.1 and is arranged on the support plate 81.3. Preferably, the preload of the compression spring 92 is adjustable. For this purpose, a threaded rod 43 is provided, which extends in the axial direction of the actuator rod 43 and is connected to it. The threaded rod extends through the first leg 91.1. A nut resting on the first leg 91.1 can be screwed into the free end region of the threaded rod 43.

[0120] The discharge valve 75 preferably has a cylindrical closure body 76. One end of the closure body 76 is detachably connected to the second leg 91.2. The closure body 76 preferably has a threaded pin 77 extending in the axial direction of the closure body 96. The second leg 91.2 has a slot 78 through which the threaded pin 77 extends. A nut 79 is screwed onto the threaded pin 77, thereby detachably securing the closure body 76 to the second leg 91.2.

[0121] To allow valve unit 2 to be detachably secured to the mounting module, a pivotable bracket 48 is provided, such as from... Figure 12 As can be seen from the image, the pivotable bracket can be connected to valve unit 2 via a snap-fit ​​mechanism. Figure 8 The bracket is shown in the connected position. As a result, the mounting module is detachably connected to the valve unit.

[0122] To release the mounting module from the valve unit, or vice versa, the release screw connection is used to connect the closure 76 of the discharge valve 75 to the second leg 91.2 of the transmission element 90. The pivotable bracket is then released from the valve unit, as... Figure 12 As shown. Valve unit 2 can be removed from mounting module 4. Maintenance work can be performed on the valve unit.

[0123] Figure 11 The operation state of the first valve 30 and the second valve 50 being closed is shown. The discharge valve 75 is open. If actuator 3 is actuated, that is, if the rod of actuator 3 is... Figure 11 When valve unit 2 in the diagram moves vertically upwards, top component 81 moves upwards. During this movement, transmission element 90 also moves upwards vertically, resulting in the closure of the discharge valve 76. When the actuator is further actuated, the compression spring is compressed, thus keeping the closure of the discharge valve 76 in the closed position. Only after a predetermined stroke is reached does the first abutment 85.1 begin to abut against the first piston shaft 35 at 46.1. The second abutment 85.2 begins to abut against the second piston shaft 55 at 46.2. Continued upward movement of top component 81 drives the first piston shaft 35 and the second piston shaft 55, resulting in the first valve 30 and the second valve 55 being moved to the open position.

[0124] Figure 14 A further embodiment of a valve unit 100 for milking dairy animals is shown in a front view. The valve unit 100 includes a first valve 110. The first valve 110 has an inlet nozzle 111 that can be connected to a pipeline (not shown) of the milking equipment.

[0125] The first valve 110 includes a housing 112. In a preferred exemplary embodiment, the housing 112 of the first valve 110 is formed of a plurality of components. The housing 112 has a housing body 113. The housing body 113 has an inlet nozzle 111. The housing body 113 is detachably connected to a housing cover 114. A first piston shaft 115 extends out of the housing cover 114.

[0126] The second valve 140 is also configured in a similar manner. The second valve 140 has an outlet nozzle 141 formed on the housing body 143 of the housing 142. The housing body 143 is detachably connected to the housing cover 144. The second piston shaft 145 of the second valve 140 extends through the housing cover 144.

[0127] Housing covers 114 and 144 can be configured as separate components. Specifically, they can be... Figure 7 As can be seen, the shell covers 114 and 144 are formed as single structural units.

[0128] A radially outwardly pointing flange 116 is provided on the side surface of the housing cover 114. The second valve 140 also has a radially outwardly pointing flange 146 on its housing cover 144.

[0129] The housing body 113 has a groove 117 in the end region opposite to the housing cover 114. The second valve 140 has a housing body 143 and a groove 147 formed opposite to the housing cover 144.

[0130] A housing component 200 is provided, which connects to the end region of the housing body 113 of the first valve 110 opposite to the housing cover 114, and to the end region of the housing body 143 of the second valve 140 opposite to the housing cover 144. The housing component 200 has a connecting device 201. The connecting device 201 is preferably designed as a threaded hole. In a preferred configuration, the threaded hole of the connecting device 201 is screwed into a threaded rod 202. The threaded rod 202 extends from the connecting device 201 toward the housing covers 114, 144. A first clamping element 203 is fixed to the threaded rod 202.

[0131] The first clamping element 203 is designed such that its edge region extends into the groove 117 of the first valve 110, and a further edge region extends into the groove 147 of the second valve 140. This configuration achieves a form-fit and force-fit connection between the first clamping element 203 and the housing body 113 of the first valve 110 and the housing body 143 of the second valve 140.

[0132] From this diagram, in particular Figure 15As can be seen, the nut 204 is screwed onto the threaded rod 203 and rests on the first clamping element 203. By rotating the nut, the distance between the first clamping element 203 and the connecting device 201 can be changed, thereby creating a force-fit connection between the housing component 200 and the housing body 113 of the first valve 110 and the housing body 143 of the second valve 140.

[0133] Figure 14 and Figure 15 A second clamping element 205 is shown. A threaded rod 202 extends through the second clamping element 205. The second clamping element 205 has a first edge region that rests on the flange 116 of the housing cover 114 of the first valve 110. The second clamping element 205 has a second edge region that rests on the flange 146 of the second valve 140. A nut 206 is provided to secure the second clamping element 205. By means of the nut 206, forces acting on the housing covers 114 and 144 can be applied to the second clamping element 205, thereby connecting the housing cover 114 of the first valve 110 to the housing body 113 of the first valve 110. The housing cover 144 and housing body 143 of the second valve 140 also correspond in this manner.

[0134] The aforementioned fixing and connection of housing component 200 to housing body 113, 143 and housing cover 114, 144 is as described above. Figure 14 A front view of the valve unit 100 is shown. Preferably, a corresponding configuration is also provided on the rear side of the valve unit, which to some extent conforms to... Figure 3 This is shown in the cross-sectional diagram.

[0135] In particular, from Figure 15 and Figure 16 It can be seen that slots 117 or 147 are defined by radially outwardly pointing ribs 118 or 148, wherein each rib 118, 148 is part of the housing body 113 or 143. Specifically, from... Figure 16 It can be seen that ribs 118 and 148 each have teeth 119 and 149, respectively.

[0136] The housing component 200 preferably has a configuration corresponding to the respective teeth 119, 149, particularly at least one cam 211.1, 211.2. Cam 211.1 engages between the teeth of tooth 119, while cam 211.2 engages between the teeth of tooth 149.

[0137] from Figure 16 It can be seen that the housing bodies 113 and 143 are arranged such that the longitudinal axes of the inlet nozzle 111 of the first valve 110 and the outlet nozzle 141 of the second valve 140 are located on a common straight line A.

[0138] The meshing teeth create the possibility of aligning the housing bodies 113 and 143 with each other during valve unit assembly, enabling compensation for any angular misalignment that may exist between the milking line portion connected to the inlet nozzle 111 and the milking line portion connected to the outlet nozzle 141. Figure 4 and Figure 5 The diagram illustrates the "tilted" arrangement of the inlet nozzle 111 and the outlet nozzle 141. Figure 5 It can be seen that the inlet nozzle 111 is offset by an angle B relative to the outlet nozzle 141.

[0139] In another embodiment not shown, housing bodies 113 and 143 are arranged relative to each other such that teeth 119 and 149 of housing bodies 113 and 143 mesh with each other.

[0140] Figure 19 Showing along according to Figure 20 The cross-sectional diagram of the cross-section line EE. From... Figure 7 As can be seen from the cross-sectional view, the first valve 110 has a first moving piston 120. The first moving piston 120 of the first valve 110 has a first piston shaft 115. The first piston shaft 115 is formed in two parts. It has a first portion 115.1 and a second portion 115.2 of the piston shaft. The first portion 115.1 and the second portion 115.2 of the piston shaft are detachably connected to each other. This connection is preferably a form-fit and / or force-fit connection, particularly a screw connection. The first piston shaft 115 extends through a diaphragm seal 124. The diaphragm seal 124 is formed with the first portion 115.1 and the second portion 115.2 of the piston shaft such that the diaphragm seal 124 is arranged between the first portion 115.1 and the second portion 115.2 of the piston shaft and thereby fixed to the first piston shaft 115. The diaphragm seal 124 has a circumferential edge region formed in the form of a bead, which is positioned in a sealing manner between the housing body 113 and the valve cover 114.

[0141] The first moving piston 120 has a closure 122 at one end, by means of which the outlet 123 of the first valve 110 can be opened and closed.

[0142] exist Figure 20 In the illustrated operating position, the outlet 123 of the first valve 110 is closed by the sealing body 122, thereby eliminating fluid connection between the inlet nozzle 111 and the outlet 123. The first moving piston 120 can be moved to the open position, as shown. Figure 24 As shown, this creates a fluid connection between the inlet nozzle 111 and the outlet 123.

[0143] Figure 20The second valve 140 is shown to have a second moving piston 150. The second moving piston 150 has a second piston shaft 145, which comprises two parts: a first part 145.1 and a second part 145.2. Shaft parts 145.1 and 145.2 are detachably connected to each other. Shaft parts 145.1 and 145.2 are preferably screwed together. The second moving piston 150 has a closing body 152. The closing body 152 of the second valve 140, according to… Figure 20 In the diagram, the inlet 153 is closed, so that there is no fluid connection between the inlet 153 and the outlet nozzle 141.

[0144] The second piston shaft 145 extends through the diaphragm seal 154. The diaphragm seal 154 is formed with the first portion 145.1 and the second portion 145.2 of the piston shaft such that the diaphragm seal 154 is disposed between the first portion 145.1 and the second portion 145.2 of the piston shaft and thereby fixed to the second piston shaft 145. The diaphragm seal 154 has a circumferential edge region formed in the form of a bead, which is positioned in a sealing manner between the housing body 143 and the housing cover 144.

[0145] The housing 200 has a channel 160 that connects the outlet 123 of the first valve 110 to the inlet 153 of the second valve 140. Channel 160 has a passage 161. Passage 161 has a valve seat 162. Passage 161 can be used by means of… Figure 20 The discharge valve 180 shown in the diagram is either closed or open.

[0146] The discharge valve 180 has a valve body 181. The valve body 181 is connected to an actuation unit, which enables the valve body 181 to move from an open position to a closed position and vice versa. Figure 7 The open position of valve body 181 is shown. Valve body 181 is substantially circular in cross-section. At its free end is a sealing element 182 that interacts with valve seat 162. From... Figure 20 It can be seen that the free space 183 surrounds the valve body 181. In the open position of the valve body 181, there is a fluid connection between the channel 160 and the free space 183. If the valve body 181 moves to... Figures 22 to 24 At the location shown, the fluid connection between channel 160 and free space 183 is interrupted.

[0147] Back Figures 14 to 18 As can be seen, the housing component 200, which also houses the discharge valve 180, has a first port 190 and a second port 191. Ports 190 and 191 are fluidly connected to the free space 183. Ports 190 and 191 are preferably arranged to be radially offset, i.e., offset by 180° when viewed in the circumferential direction of the free space 183. Fluid can flow into the free space 183 through port 190 and flow out through the second port 191.

[0148] From the basis Figure 20 As can be seen from the diagram, in the open position of the discharge valve 180, the free space 183 is preferably connected to the atmosphere.

[0149] The valve unit configuration according to the invention allows for a variety of cleaning possibilities, depending on the location of the first valve, the second valve, and / or the drain valve.

[0150] If the discharge valve 180 is in the closed position, this means that the passage 161 leading to the channel 160 is closed, so cleaning of the free space 183 can be carried out by allowing cleaning fluid to be guided into the free space through one port and out through the other port.

[0151] If the discharge valve 180 is in the open position, this means that passage 160 is fluidly connected to free space 183, and the first valve 110 and the second valve 140 are closed, allowing fluid within the passage, particularly milk, to be directed out via one port 190 or the other port 191. In these operating positions of the valves, cleaning of passage 160 and free space 183 can be performed by directing cleaning fluid into free space 183 via one port 190 and out via the other port 191.

[0152] In a preferred configuration, with the discharge valve 180 in the open position, the free space 183 can be connected to the atmosphere. In this operating position, fluid, particularly milk, in the passage 160 can be drawn out from the discharge valve 180.

[0153] The first valve 110, the second valve 140, and the discharge valve 180 form a valve unit also known under the name "block-discharge-block". Figure 20 In the positions shown, the first valve 110 and the second valve 140 are closed, meaning they are in the blocking position. The discharge valve 180 is in the open position, meaning it is in the discharge position.

[0154] In a preferred embodiment, the valve unit is operated such that, in an operating position also known as a transition position, all valves—meaning the first valve 110, the second valve 140, and the discharge valve 180—are closed, as shown below. Figure 22 As shown.

[0155] Figure 24Further operating positions of the valve unit are shown, with the first valve 110 and the second valve 140 open. The discharge valve 180 is closed. If fluid (particularly milk) flows into the first valve 110 through inlet nozzle 111, the fluid exits the first valve 110 through outlet 123 and flows into passage 160. The fluid flows out of passage 160 through inlet 153 into the second valve 140 and exits the latter via outlet nozzle 141. Here, in Figure 24 In the text, flow is indicated by arrows.

[0156] In this operating position, the discharge valve 180 is closed. Specifically, from... Figure 24 As can be seen, the valve body 181 has a seal 184 in the end region opposite the sealing element 182. When the discharge valve 180 is closed, as... Figure 24 As illustrated, the seal 184 rests on the inner wall of the housing component 200, thus sealing the free space 183 relative to the channel 160 and relative to the atmosphere. In this operating condition, it is possible to clean the free space 183, particularly by flushing it by connecting the port 190 to a fluid source (especially a water container or the like), allowing fluid (preferably water) to flow through the port 190 into the free space 183 and exit again via the port 191.

[0157] Figure 25 A preferred embodiment of the device 300 is shown in perspective. The device 300 includes a valve unit 100 coupled with an actuation unit 320. The actuation unit 320 also forms a mounting module. The mounting module and the valve unit together form the device.

[0158] The mounting module allows for connection and disconnection from the valve unit. The mounting module can be secured to the structure. During this type of use of the device, the valve unit is released as a separate unit. It is also possible that the valve unit remains securely connected to the portion of the milking equipment piping while the mounting module is detached and removed from the valve unit.

[0159] Due to the device's design configuration, its complexity is reduced. In particular, this design configuration creates the possibility of performing maintenance work on the valve unit more easily. If the mounting module and valve unit are separated, seal replacement can be simplified. This also means that maintenance time, such as replacing diaphragm seals and possibly diaphragm seals with pistons, can be reduced. A further advantage is that, in the event of a failure of the actuator included in the actuation unit, the mounting module containing the actuator can be replaced.

[0160] The mounting module and the valve unit are geometrically matched, allowing the mounting module to be connected to the valve unit in a specified, predefined position. The connection between the valve unit and the mounting module is preferably a form-fit connection. It can be specifically configured as a snap-fit ​​connection. The mounting module for this purpose has suitable snap-fit ​​protrusions that engage with correspondingly designed stops on the valve unit. This will be explained further below.

[0161] In the vertical alignment of the device 300, the actuation unit 320 has an upper mounting plate 322 and a lower mounting plate 324. The actuator 330 is securely connected to the upper mounting plate 322 and the lower mounting plate 324 and is positioned between them (see, for example, [reference needed]). Figure 19 The upper mounting plate 322 has a fastening portion 323. In the illustrated exemplary embodiment, the lower mounting plate 324 also has a fastening portion 325. The fastening portions 323 and 325 are preferably located in a common plane. By means of the fastening portions 323 and 325, the actuation unit 320 can be fixed to, for example, a structure (not shown), preferably a wall or support.

[0162] The fastening portion 323 and the upper mounting plate 322, as well as the fastening portion 325 and the lower mounting plate 324, are substantially L-shaped in cross-section.

[0163] The actuator 330 is preferably formed as a piston-cylinder unit. This is particularly true of a pneumatic piston-cylinder unit, the ports of which are not shown. The actuator 330 is connected to a controller (not shown), thereby enabling the actuator 330 to be activated and deactivated according to a control signal. If the actuator 330 is activated, the rod 332 of the actuator 330 moves out of the cylinder of the actuator 330 (see [link to controller]). Figure 21 , Figure 10 ).

[0164] The free end of the rod 332 of the actuator 330 rests on the top component 340. The top component 340 has a support plate 342. The support plate 342 is preferably aligned parallel to the upper mounting plate 322.

[0165] L-shaped retaining plate 346 is pivotally connected to support plate 342. Support plate 342 has slots into which protrusions from legs 347 extend. These slots and legs mate with each other, allowing retaining plate 346 to pivot a certain amount, which will be discussed further.

[0166] The two guide members 350 and 352 are preferably connected to the support plate 342. The guide members 350 and 352 are preferably guide members with a circular cross-section. Figure 13 It can be seen that the guides 350 and 352 extend from the support plate 342 through the upper mounting plate 322 and through the lower mounting plate 324.

[0167] A transmission element 360 is provided. The discharge valve 180 of the valve unit 100 is actuated by means of the transmission element 360. The transmission element 360 is preferably U-shaped. It has a first leg 362 and a second leg 364 that are spaced apart from each other and parallel to each other. The legs 362 and 364 are preferably arranged parallel to the support plate 342. Each leg 362 and 364 has its own guides 350 and 352 passing through an extended through opening.

[0168] From the basis Figure 26 As can be seen from the diagram, the lower mounting plate 342 is positioned between the first leg 362 and the second leg 364 of the transmission element 360. A first compression spring 370 surrounding the guide member 350 is positioned between the first leg 362 and the lower mounting plate 324.

[0169] The guide member 350 has an abutment member 354 disposed between a retaining plate 346 and a first leg 362 in the axial direction of the guide member 350. The guide member 352 has an abutment member 356 disposed between a retaining plate 346 and a second leg 364 in the axial direction of the guide member 352.

[0170] The second guide member 352 preferably has a corresponding second compression spring 372. The second compression spring 372 rests on the lower mounting plate 324 and the first leg 362. The guide members 350, 352 and the transmission element are preferably symmetrically formed so as to avoid tilting during the displacement of the transmission element 360 along the guide members 350, 352.

[0171] The valve body 181 of the discharge valve (vent valve) of valve unit 100 is mounted on the support leg 364. The valve body 181 is preferably detachably connected to the support leg 364 of the transmission element 360.

[0172] Specifically from the basis Figure 13 As can be seen from the illustration, two spring elements 390 and 392 are provided. Spring elements 390 and 392 are preferably tension springs. The free ends of each spring element 390 and 392 are connected to the top member 340, preferably to the retaining plate 346. In practical terms, this is achieved, for example, by the retaining plate 346 having a cutout with lugs engaging in the holes at the free ends of the spring elements.

[0173] The opposite ends of spring elements 390 and 392 are connected to the lower mounting plate 324.

[0174] The lower mounting plate 324 has a profile that matches the housing component 200 of the valve unit, such that when the valve unit 100 is connected to the actuation unit 300, the end face of the lower mounting plate 324 rests on the housing component 200. Figure 26The lower mounting plate 342 shows two rear handles 326, 327 spaced apart from each other, which are in particular hook-shaped. The housing component 200 has two pins 207 spaced apart from each other. Figure 2 The pistons extend substantially vertically when vertically aligned, i.e., when the piston shafts 115 and 145 extend vertically. Each pin 207 has two stops 208 and 209 spaced apart in the axial direction of the respective pin 207. A radially outwardly pointing web 210 is provided between the stops.

[0175] If valve unit 100 is connected to actuation unit 320, the rear handles 326, 327 engage at least partially around each pin 207. Each rear handle 326, 327 has a notch into which the web 210 of the associated pin 207 engages. In this way, a detachable form-fit connection is formed between housing component 200 and lower mounting plate 324. Stops 208, 209 define the position of housing component 200, and thus also the valve unit, relative to lower mounting plate 242 in the vertical direction.

[0176] The upper mounting plate 322 has a profile that matches the housing covers 114, 144 of the valve unit 100, such that when the valve unit 100 is connected to the actuation unit 320, the end face of the upper mounting plate 344 rests partially on the respective housing covers 114, 144. Figure 13 The display shows that the mounting plate 344 has two rear handles 328 that are hook-shaped and spaced apart from each other.

[0177] The housing cover 114 has first and second ribs 125.1 and 125.2. The first rib 125.1 and the second rib 125.2 are located in a common plane and extend substantially parallel to the longitudinal axis of the first piston shaft 115. The first rib 125.1 and the second rib 125.2 are spaced apart from each other such that, in the assembled state, the upper mounting plate 322 engages between the first rib 125.1 and the second rib 125.2.

[0178] The housing cover 144 has a first rib 151.1 and a second rib 151.2. The first rib 151.1 and the second rib 151.2 are located in a common plane and extend substantially parallel to the longitudinal axis of the second piston shaft 120. The first rib 151.1 and the second rib 151.2 are spaced apart from each other such that, in the assembled state, the upper mounting plate 322 engages between the first rib and the second rib (see...). Figure 20 ).

[0179] It is equipped with a locking device 380, which is particularly capable of locking from Figure 19As can be seen, the locking device 380 has a first leg 381 and a second leg 382, ​​each wedge-shaped. In the assembled state, the first leg 381 rests on the first rib 125.1 and the second rib 125.2 of the housing cover 114 and extends through the rear handle of the upper mounting plate 322. Similarly, the second leg 328 rests on the first rib 151.1 and the second rib 151.2 of the housing cover 144 and extends through the rear handle of the upper mounting plate 322. Due to the geometric configuration, especially the geometry of the legs, a form-fit and force-fit connection is achieved between the housing covers 114 and 144 and the upper mounting plate 322.

[0180] The first piston shaft 115 of the first valve 110 and the second piston shaft 145 of the second valve 140 extend toward the retaining plate 346. The retaining plate 346 has openings 345.1 and 345.2. The free end portion of the first piston shaft 115 extends into opening 345.1. At a distance from the free end portion of the first piston shaft 115, the first piston shaft 115 has a circumferential stop 127. The free end portion of the second piston shaft 145 of the second valve 140 extends into opening 345.2. At a distance from the free end portion of the second piston shaft 145, the latter has a circumferential stop 154.

[0181] Figure 19 and Figure 20 The device is shown in an operating state where the first valve 110 and the second valve 140 are closed and the discharge valve 180 is open. In this operating state, the rod 332 of the actuator 330 is at least partially retracted. The support plate 342 is at a distance from the stop 127 of the first valve 110 and the stop 154 ​​of the second valve 140. The retaining plate 346 rests on the stop 127 of the first valve 110 and the stop 154 ​​of the second valve 140. For this operating state, the total spring force of the spring elements 390 and 392 is sufficient to close the first valve 110 and the second valve 140.

[0182] Spring elements 390 and 392 apply tensile force to guides 350 and 352 connected to retaining plate 346. Abutments 354 and 356 of guides 350 and 352 act on first leg 362, thereby overcoming the total spring force from the first and second compression springs 370 and 372 to open discharge valve 180.

[0183] The stroke of the discharge valve 180 is preferably selected such that the discharge valve 180 is opened, allowing cleaning of the discharge valve 180, particularly the free space 183 and the passage 160, to be performed. In particular, alternatively or additionally, the stroke of the discharge valve 180 may be selected such that when the discharge valve 180 is open, the free space 160 and the passage are connected to the surrounding atmosphere.

[0184] Figure 21 and Figure 22 The device is shown in an operating state where the first valve 110, the second valve 140, and the discharge valve 180 are all closed. In this operating state, the rod 332 of the actuator 330 is partially extended. The support plate 342 is at a distance from the stop 127 of the first valve 110 and the stop 154 ​​of the second valve 140, wherein the distance in this operating state is less than the distance in the operating state where the first valve 110 and the second valve 140 are closed and the discharge valve 180 is open. Specifically, the stroke of the actuator rod 322 corresponds to the stroke of the guides 350, 352 with their abutments 354 and 356. The stroke of the abutments 354 and 356 of the guides 350, 352 has the effect of releasing the compression springs 370, 372, causing the transmission element 360 to move along the axial direction of the guides 350, 352 and close the discharge valve 180. The time interval during which the valve unit is in this transition position preferably depends on the dynamic conditions and / or the actuator controller.

[0185] Figure 23 and Figure 24 The device is shown in an operating state where both the first valve 110 and the second valve 140 are open. The discharge valve 180 is closed. In this operating state, the rod 332 of the actuator 330 extends. As the rod 332 extends, the support plate 342 enters contact with the stops 127 and 154, and the pistons 120 of the first valve 110 and 150 of the second valve extend so far that the valves change to the open state. The guides 350 and 352 connected to the support plate 342 are also moved. The stroke of the abutments 354 and 356 of the guides 350 and 352 can have the effect of further releasing the compression springs 370 and 372, thereby increasing the closing force of the discharge valve.

[0186] The locking device 380 is preferably usable as a tool. Legs 381 and 382 can be inserted between the support plate 342 and the retaining plate 346. By pivoting the locking device 380, the retaining plate 346 is pivoted in such a way that the free end portions of the first piston shaft 115 and the second piston shaft 145 disengage from openings 345.1 and 345.2, thereby separating the valve unit from the top component 340. The valve unit can then be separated from the lower mounting plate 324.

[0187] The preferred configuration of the actuator unit also has the advantage that, in the event of a failure of the actuator and / or the controller connected to the actuator, the first and second valves are closed and the discharge valve is opened. This has the advantage that, viewed in the direction of milk flow, milking system components arranged downstream of the valve unit, such as milk tanks, are not contaminated by the fluid, especially the cleaning fluid.
