Description

[0001] Valve disc, method for producing a valve disc, valve unit and fluid line system

[0002] The disclosure relates to a valve disc for a valve unit, a method for producing a valve disc, a valve unit for a fluid line system and a fluid line system.

[0003] Fluid line systems are particularly used in electric vehicles. Electric vehicles typically have a thermal management system that can adjust or regulate the temperature of various components. Cooling fluids, such as coolants or refrigerants, are used for this purpose and can be distributed through the fluid line system.

[0004] For example, the temperature of an electric vehicle's battery typically needs to be controlled and / or regulated. To ensure optimal performance and service life, its operating temperature and corresponding temperature ranges typically need to be precisely monitored and regulated.

[0005] In addition to the battery, other components may also need to be cooled, or at least their temperature monitored, controlled, adjusted, or regulated. For example, electric motors and power electronics generate heat during operation and must be cooled accordingly to prevent overheating and performance degradation. Cooling may also be required for chargers and DC-DC converters. Chargers and DC-DC converters convert energy for the battery and other electrical systems and also generate heat that must be dissipated to ensure efficient performance.

[0006] Furthermore, interior air conditioning, for example, of a vehicle cabin or vehicle interior, may be desirable. In particular, adjusting heating, cooling, and / or ventilation may be necessary to ensure occupant comfort.

[0007] This results in a large number of components whose fluid supply must be regulated. A fluid distribution system and a valve unit for an electric vehicle are known, for example, from EP 3 746 322 Bi. However, the valve unit disclosed therein only has limited flexibility, so that a comparatively large number of valve units and corresponding feed pumps and fluid channels are required. This makes the fluid distribution system more complex and has comparatively large dimensions. The valve unit is also limited in the number of different flow paths or fluidic connections, and thus in the number of fluid channels that can be connected and / or selected. This results in comparatively high equipment expenditure and a comparatively large amount of space is required for installation, e.g. in an electric vehicle.

[0008] In addition, the valve disc and the valve unit must be sealed, at least partially or completely, to prevent unwanted leakage during fluid flow. A leak can be defined as the unintentional escape of fluid from the valve disc or the valve unit. A leak can damage electrical components, in particular. Leakage can also result in fluid being lost from the fluid distribution system and / or a circuit. Such a loss can impair the functionality of components, such as cooling units. A suitable seal should be securely attached to prevent it from becoming loose or lost. Good sealing properties are also desirable.

[0009] The object of the present invention is to overcome these disadvantages. The invention is defined by the main claim and the subordinate claims. The respective dependent claims relate to advantageous embodiments.

[0010] One aspect of the disclosure relates to a valve disc for a valve unit, wherein the valve disc has a valve disc line system through which a fluid can flow through the valve disc between at least two flow openings arranged on an outer surface of the valve disc, wherein the valve disc has a sealing arrangement arranged on the outer surface of the valve disc such that it does not cover any of the flow openings on the outer surface, wherein the sealing arrangement has a base element protruding from the outer surface, a seal and an adhesion promoter arranged between the base element and the seal.

[0011] The valve disc is particularly designed to be accommodated in a valve unit. Since the valve discs are rotatable, or can be rotated to adjust flow paths through the valve unit, a good and secure attachment of the seal is necessary. Because the base element protrudes from the outer surface, a defined surface can be created on or at which the adhesion promoter and / or the seal is or will be arranged. This can ensure, for example, that the seal can be arranged accurately and / or precisely. The protruding base element makes it easier to apply and / or arrange the adhesion promoter and / or the seal. The base element can serve as an alignment aid for the adhesion promoter and / or the seal.

[0012] The bonding agent allows the seal to be securely and firmly attached to and / or onto the base element. The bonding agent allows the seal to be securely and firmly attached to the base element. This overcomes the disadvantages of conventional seals.

[0013] The sealing arrangement can serve to seal the flow openings of the valve disc against leakage. For example, the sealing arrangement can prevent or at least counteract leakage when a fluid flows through the valve disc, e.g., through the valve disc's piping system.

[0014] Leakage can refer to an unwanted flow. Leakage can refer to the unwanted escape of fluid from the valve disc. Leakage can refer to an unwanted fluidic connection and / or fluid flow between different channels, e.g., different flow lines, of the valve line system. A leakage flow can be or include a corresponding fluid flow of the leak. A leakage flow can be a fluid flow caused by a leak.

[0015] The base element may extend away from the outer surface. The outer surface may comprise one or more sides of the valve disc. A side of the valve disc may be or comprise a flat side, an end face, and / or a shell side. The valve disc may include a valve disc body. The valve disc body may include the outer surface. The base element may protrude from the valve disc body.

[0016] A sealing arrangement that does not cover the flow openings on the outer surface can be arranged such that it is not arranged in a flow opening on the outer surface. This does not necessarily rule out the possibility of the sealing arrangement being arranged above the valve line system and / or crossing the valve line system. For example, material from the valve disc can be arranged between the sealing arrangement and the valve line system and / or a flow line. A sealing arrangement that does not cover the flow openings on the outer surface can be arranged such that it does not protrude over a flow opening and / or extend over a flow opening and / or does not run over a flow opening. A sealing arrangement that does not cover the flow openings on the outer surface can be arranged such that it does not divide the flow opening into partial openings, at least in sections.A sealing arrangement which does not cover the flow openings on the outer surface can be arranged in such a way that it does not impede or block the inflow into the flow opening and / or the outflow from the flow opening.

[0017] The base element can comprise a metal or be made of metal. Alternatively or additionally, the base element can comprise a metal alloy or be made of a metal alloy. The base element can be made of the same material as the valve disc and / or the outer surface of the valve disc, or have the same material. The valve disc can be made of a metal or have a metal. Alternatively or additionally, the valve disc can be made of a metal alloy or have a metal alloy.

[0018] In some embodiments, the base element may be formed integrally with the valve disc and / or the valve disc body. In some embodiments, the base element may be formed integrally with the outer surface. A base area of ​​the base element may be smaller than the outer surface area.

[0019] The adhesion promoter can serve to ensure that the seal is securely and reliably attached and / or positioned on or to the base element. The adhesion promoter can, for example, be bonded to the base element and / or the seal through a chemical reaction.

[0020] The sealing arrangement can at least partially enclose at least one, several, or all of the flow openings on the outer surface. Alternatively or additionally, the sealing arrangement can completely enclose at least one, several, or all of the flow openings on the outer surface.

[0021] The base element can be or have a web. For example, the base element can be or have a metal web. A web can be an element that extends elongately. However, the base element is not necessarily limited to a web and / or web-shaped elements. For example, the base element can be flat and / or plate-shaped at least in sections. For example, the base element can be annular at least in sections. The base element can be rectilinear at least in sections. The base element can be curved and / or arcuate at least in sections.

[0022] One or the base area of ​​the base element may be larger than one or the base area of ​​the seal.

[0023] The seal may comprise or consist of a vulcanized elastomer material. The vulcanized elastomer material may, for example, be or comprise a rubber and / or a rubber. The elastomer material and / or the seal may be or comprise nitrile rubber (NBR). Alternatively or additionally, the elastomer material and / or the seal may be or comprise fluororubber (FKM). Alternatively or additionally, the elastomer material and / or the seal may be or comprise silicone rubber (VMQ). However, the elastomer material and / or the seal is not limited to these.

[0024] It may be provided that the seal can be vulcanized onto the base element. The seal can be vulcanized together with the adhesion promoter. The seal can be chemically bonded to the adhesion promoter. The adhesion promoter can enable and / or provide a strong chemical bond between the base material and the seal, and / or between the base material and / or the elastomer material.

[0025] The adhesion promoter may comprise one or more silanes and / or one or more organic polymers. The adhesion promoter may consist of one or more silanes and / or one or more organic polymers.

[0026] The valve disk line system can have one or more flow lines, which in some embodiments can be fluidically separated from one another. It can be provided that at least two, several or all flow lines of the valve disk line system can be fluidically separated. If two flow lines are fluidically separated, it can be provided that they do not have any common flow openings. If two flow lines are fluidically separated, it can be provided that no fluid can flow and / or be exchanged between the two flow lines in the valve disk. The seal and / or the sealing arrangement can fluidically seal the flow lines from one another at the flow openings. The seal and / or the sealing arrangement can be designed to fluidically seal the flow lines from one another at the flow openings.

[0027] At least one flow line can be curved. It can be provided that at least one flow line can run at an angle of approximately 90°. Alternatively or additionally, at least one flow line can be configured to deflect a fluid flowing through the flow line by an angle of approximately 90°.

[0028] At least one flow line may have at least one flow opening. One or more flow openings may, for example, be spaced radially from the rotation axis.

[0029] At least one flow line can run from one flat side of the valve disc to another flat side of the valve disc opposite the flat side.

[0030] At least one flow line can run transversely to a rotational axis and / or parallel to a flat side of the valve disc. At least one flow line can run transversely to a rotational axis and / or parallel to a flat side of the valve disc. At least one flow line can run transversely to an axis of symmetry of the valve disc.

[0031] The flow lines and / or flow openings can be arranged and / or selected such that, when the valve disc is accommodated in a valve unit, they can enable certain fluidic connections between the openings of the valve unit at certain rotational positions of the valve disc. The flow lines and / or flow openings can be arranged and / or selected such that, when the valve disc is accommodated in a valve unit, they can block certain fluidic connections between the openings of the valve unit at certain rotational positions of the valve disc.

[0032] The valve disc line system can be configured to form a heat exchanger. A first flow line and a second flow line can be arranged and / or extend in the valve disc in such a way that they form a heat exchanger. The heat exchanger can be, for example, a counterflow heat exchanger. The heat exchanger can be, for example, a cocurrent heat exchanger. The heat exchanger can be, for example, a crossflow heat exchanger. The type and / or nature of the heat exchanger can depend on the flow guidance, flow direction, and / or arrangement of the flow lines. The flow lines can be arranged in such a way that a desired type and / or nature of heat exchanger can result.

[0033] The valve disc may have a mixing chamber. A first flow line and a second flow line may be fluidically connected to the mixing chamber, so that fluid transported by the first flow line and fluid transported by the second flow line can be mixed in the mixing chamber.

[0034] Another aspect of the disclosure relates to a method for producing a valve disc, comprising the steps:

[0035] Providing a valve disc body having a valve disc conduit system with flow openings arranged on an outer surface of the valve disc body, wherein the valve disc body has a base element projecting from the outer surface and arranged such that it does not overlap with the flow openings;

[0036] Applying an adhesion promoter to the base element;

[0037] disposing an elastomeric material over the base member such that the adhesion promoter (62) is disposed between the base member and the elastomeric material; and

[0038] Vulcanizing the elastomer material to form a seal on the base element.

[0039] The method can be used to produce a valve disc according to one aspect of the disclosure. The method can be used to produce a valve disc according to one aspect of the disclosure.

[0040] Because the base element protrudes from the outer surface, the adhesion promoter can be applied safely, easily and reliably. Vulcanization can achieve and / or ensure a good and reliable connection between the seal and the base element. During vulcanization, the adhesion promoter can be bonded to the base element and / or the elastomer material. During vulcanization, the adhesion promoter can be chemically bonded and / or reacted with the base element and / or the elastomer material. Through vulcanization and / or vulcanization, the elastomer material can crosslink so that the seal can be formed. Vulcanization can include and / or correspond to vulcanizing the elastomer material onto the base element.

[0041] Before applying the elastomer material, the adhesion promoter can be dried. Drying can enhance the adhesion promoter's effectiveness. Drying can stabilize the adhesion promoter. It may be intended that drying can remove residues, such as moist residues, that could interfere with vulcanization.

[0042] Before arranging the elastomer material and / or before applying the adhesion promoter, the base element can be cleaned and / or roughened. This can enable, for example, better adhesion and / or better application of the adhesion promoter and / or the elastomer material. In some embodiments, the cleaning and / or roughening can comprise a chemical etching process. In some embodiments, the cleaning and / or roughening can comprise a mechanical process, for example, grinding and / or polishing. In some embodiments, the cleaning and / or roughening can comprise chemical mechanical planarization (CMP).

[0043] Before applying the adhesion promoter and / or before vulcanizing the elastomer material, a plasma treatment and / or anodization of the base element can be carried out.

[0044] The plasma treatment can, for example, be used to clean the outer surface and / or the base element. The plasma treatment can, for example, be used to apply a coating to the outer surface and / or the base element, which can increase the hardness and / or the corrosion resistance of the outer surface and / or the base element. The plasma treatment can, for example, increase the surface energy of the outer surface and / or the base element. The plasma treatment can, for example, activate the outer surface and / or the surface of the base element. The increased surface energy and / or the surface activation can, for example, improve the adhesion of the adhesion promoter and / or the elastomer material. The increased surface energy and / or the surface activation can, for example, increase the adhesion and / or wettability of the adhesion promoter and / or the elastomer material, and / or functional groups (such as-OH, -NH2, -COOH) can be attached to the outer surface and / or the base element, which can, for example, make the outer surface and / or the base element more reactive and / or ready for chemical reactions.

[0045] Anodization can, for example, form an oxide layer on the outer surface and / or on the base element. The anodization and / or the oxide layer can provide corrosion protection and / or increase wear resistance. Alternatively or additionally, the anodization and / or the oxide layer can provide electrical insulation. Alternatively or additionally, the anodization and / or the oxide layer can increase adhesion.

[0046] Providing the valve disc body can comprise forming the base element. It can be provided that forming the base element comprises machining the valve disc body to form the base element. For example, the valve disc body can be machined mechanically, e.g., by machining, to form the base element. For example, the valve disc body can be milled to form the base element. Alternatively or additionally, the base element can be formed on or with the valve disc body by additive manufacturing. For example, the base element can be formed on or with the valve disc body by build-up welding, e.g., by laser build-up welding. For example, the base element can be formed on or with the valve disc body by a 3D printing process.

[0047] It can be provided that the base element is or will be formed integrally with the valve disc body.

[0048] The elastomer material may be or comprise a vulcanized elastomer material, and the elastomer material may be vulcanized again during the formation of the seal. Alternatively, the elastomer material may comprise a not yet vulcanized material, e.g., a rubber or the like, and may be vulcanized during the vulcanization, for example, vulcanized for the first time.

[0049] The application of the adhesion promoter can comprise silanization. During silanization, the adhesion promoter can be formed as a silane, for example, and / or applied as a silane. A further aspect of the disclosure relates to a valve unit for a fluid distribution system, in particular for a fluid distribution system of an electric vehicle, wherein the valve unit has a plurality of openings through which a fluid can enter or exit the valve unit, wherein the valve unit has a valve disc according to the disclosure and at least one further rotatable valve disc with a further valve disc line system, wherein the valve disc is rotatable, wherein the valve unit is configured such that, at a first rotational position of the valve disc and / or the further valve disc, a first group of openings, preferably a first pair of openings,is fluidically connected via the valve disc line system of the valve disc and / or the further valve disc line system of the further valve disc, and at a second rotational position of the valve disc and / or the further valve disc, a second group of openings, preferably a second pair of openings, is fluidically connected via the valve disc line system of the valve disc and / or the further valve disc line system of the further valve disc, wherein at least one opening of the second group is different from an opening of the first group.

[0050] The valve disc and the further valve disc, and / or the valve disc line system and the further valve disc line system, can thus form an adjustable line system through the valve unit.

[0051] This allows for flexible switching between different flow paths using the valve unit according to the disclosure. Since a fluidic connection between two (or more) openings can be established or broken by rotating the valve disc and / or the additional valve disc, it is also possible to switch very quickly between different fluidic connections and / or to establish or break a specific fluidic connection very quickly.

[0052] Because the valve disc and the additional valve disc, and / or the valve disc line system and the additional valve disc line system, form an adjustable line system through the valve unit, a highly flexible flow guidance and combination of possible fluidic connections can be achieved by appropriately selecting the number of valve discs or additional valve discs and / or by appropriately designing the valve disc line system and the additional valve disc line system(s). "Fluidic connection" can mean that a fluid can be transported, conveyed, and / or guided between the respective fluidically connected components, devices, elements, or the like.A “flow path” can correspond to a fluidic connection of at least two openings, which can be fluidically connected to each other at a certain rotational position of the valve disc and a certain rotational position of the other valve disc.

[0053] The fluid can be, for example, liquid and / or gaseous. The fluid can be or comprise a coolant and / or a refrigerant. The fluid can be or comprise one or more of water, air, glycol, mineral oil, or cooling oil. The fluid can comprise a synthetic coolant, which can be, for example, silicone-based, glycol-based, and / or polyalkylene glycol-based.

[0054] In some embodiments, the valve unit may have exactly one additional valve disc. For example, an additional valve disc may be a second valve disc.

[0055] In some embodiments, the valve unit may have two or more additional valve discs. For example, a second and a third valve disc may be provided, and / or at least one additional valve disc may include and / or correspond to at least a second and / or a third valve disc. The present disclosure also encompasses embodiments with two or more additional valve discs. If the valve unit has two or more additional valve discs, these may include some, several, or all of the features, functions, and advantages of the valve disc and / or additional valve disc. “Additional valve disc” may also mean a plurality of additional valve discs. “Additional valve disc” may also mean “at least one of the additional valve discs.”

[0056] One or the further valve disc can be a valve disc according to the disclosure or correspond to such a valve disc. One or the further valve disc can have one, several or all features of a valve disc according to the disclosure. The further valve disc line system can correspond to a valve disc line system of a valve disc according to the disclosure. However, the flow paths of the respective valve discs or the respective valve disc line systems do not necessarily have to be identical. However, one or the further valve disc does not necessarily have to be identical to a valve disc according to the disclosure. One or the further valve disc does not necessarily have to have all features of a valve disc according to the disclosure. One or the further valve disc can have at least one different feature compared to a valve disc according to the disclosure.

[0057] It can be provided that the rotational position of the valve disc does not necessarily have to coincide with and / or correspond to the rotational position of the further valve disc. For example, with respect to a reference angle and / or a reference rotational position, the valve disc can be rotated by an angle so that it can be in its first rotational position. For example, with respect to a reference angle and / or a reference rotational position, the further valve disc can be rotated by a second angle so that it can be in its first rotational position. The first angle does not necessarily have to be the same as the first angle. For example, with respect to a reference angle and / or a reference rotational position, the valve disc can be rotated by a third angle so that it can be in its second rotational position.For example, relative to a reference angle and / or a reference rotational position, the additional valve disc can be rotated by a fourth angle so that it can be in its first rotational position. The third angle does not necessarily have to be the same as the fourth angle. It can also be provided that the respective reference angles and / or reference positions of the valve disc and the additional valve disc can be different.

[0058] The number of rotational positions of the valve disc and / or the additional valve disc is not limited to two. In some embodiments, the sum of the number of rotational positions of the valve disc and the additional valve disc can correspond to at least the number of adjustable or selectable fluidic connections and / or flow paths.

[0059] The seal of the valve disc can contact the other valve disc when the valve disc and the other valve disc are in a rest position. A rest position can mean that the respective valve discs are not rotating. A rest position can mean that the respective valve discs can be in a rotational position where they are at rest.

[0060] In the first rotational position, a first opening may be fluidly connected to a second opening, and in the second rotational position, the first opening and / or the second opening may be fluidly connected to a third opening. In the first rotational position, a first opening may be fluidly connected to the second opening, and in the second rotational position, a third opening may be fluidly connected to a fourth opening.

[0061] It can be provided that if at least two, several or all openings of the first group are fluidically connected, at least two, several or all openings of the second group cannot be fluidically connected.

[0062] However, other and / or additional fluidic connections may also be present and / or enabled depending on the respective rotational position of the valve disc and / or the additional valve disc(s). In some embodiments, additional valve discs, e.g., a third valve disc, may enable even greater variability and / or adjustability.

[0063] The valve disc and / or the additional valve disc can be detachable from the valve unit. This allows for easy replacement of the valve discs. The valve unit can also be easy to maintain and / or clean. Furthermore, the flow paths and / or fluidic connections can be changed and / or adapted by replacing one or more valve discs.

[0064] A rotational axis of the valve disc and a rotational axis of the additional valve disc can be aligned parallel. Alternatively or additionally, it can be provided that a rotational axis of the valve disc and a rotational axis of the additional valve disc can coincide. In some embodiments, a rotational axis of the valve disc and a rotational axis of at least one, several, or all additional valve discs can be aligned parallel and / or coincide. This can result in a particularly simple flow guidance.

[0065] The further valve disc can be spaced from the valve disc in the direction of the axis of rotation. In some embodiments, the further valve disc can be arranged above the valve disc. If the valve unit has more than two valve discs, these can each be spaced from one another, arranged one above the other and / or stacked. This can result in a compact design of the valve unit. The valve unit can be comparatively small. The further valve disc can be rotatable independently of the valve disc. It can be provided that the valve disc and all further valve discs can be rotatable independently of one another and / or can be or be moved independently of one another.

[0066] It can be provided that the valve disc and the further valve disc, and / or adjacent valve discs, can be sealed so that no leakage or the like can escape between the respective valve discs and / or is at least minimized. Leakage can be an undesired fluid discharge.

[0067] The valve disc and / or the additional valve disc can be configured as an expansion valve. In some embodiments, a function as an expansion valve can result depending on the rotation of the valve disc and / or the additional valve disc. For example, an expansion valve can be formed or become formed by selecting an overlap or a flow cross-section, and / or a corresponding function can be provided or become provided.

[0068] A flow cross-section can be varied at a flow opening of the valve disc line system depending on the rotation of the valve disc and / or the further valve disc.

[0069] A flow cross-section at a flow opening of the further valve disc line system can be variable depending on the rotation of the further valve disc and / or the rotation of the valve disc.

[0070] It can be provided that an overlap of a flow opening of the valve disc line system with one or more flow openings of the further valve disc line system can be adjustable depending on the rotation of the valve disc and / or the further valve disc. For example, this makes it possible to adjust the amount of fluid, e.g., a mass flow and / or a volume flow, that can flow from the valve disc into the further valve disc (or vice versa).

[0071] If the valve unit has at least two further valve discs, an overlap of a flow opening of the further valve disc line system of one of the further valve discs with one or more flow openings of the further valve disc line system of another of the further valve discs can be adjustable depending on the rotation of one further valve disc and / or the other further valve disc.

[0072] An overlap of a flow opening of the valve disc line system with at least one opening of the valve unit can be adjustable depending on the rotation of the valve disc. It can be provided that an overlap of a flow opening of the further valve disc line system with at least one opening of the valve unit can be adjustable depending on the rotation of the further valve disc. This makes it possible to adjust, for example, a quantity of fluid, for example a mass flow and / or a volume flow, that can flow from the valve disc and / or the further valve disc into the opening.

[0073] The valve disc and / or the additional valve disc can be adjustable in an axial direction. Alternatively or additionally, the valve disc and / or the additional valve disc can be adjustable in a direction parallel to the rotational axis of the valve disc and / or the additional valve disc. Alternatively or additionally, the valve disc and / or the additional valve disc can be adjustable in a direction perpendicular to the rotational direction of the valve disc and / or the additional valve disc.

[0074] For example, a flow cross-section and / or an overlap between a flow opening of the valve disc and an opening, and / or between a flow opening of the further valve disc and an opening, can be adjustable.

[0075] It can be provided that in the case of an axial adjustment, the valve disc and the further valve disc are or will be adjusted equally and / or by the same adjustment distance.

[0076] In some embodiments, it can be provided that the valve disc is or will be axially adjusted when it is or is being moved. It can be provided that the valve disc is axially adjusted when the valve disc rotates. This means, for example, that the seal of the valve disc does not come into contact with the further valve disc and / or the housing of the valve unit when the valve disc rotates. This means, for example, that the seal of the valve disc is or will be pressed less strongly onto the further valve disc and / or the housing of the valve unit when the valve disc rotates. This can facilitate the rotation of the valve disc and / or prevent or at least reduce wear of the seal due to friction. In some embodiments, it can be provided, for example, that before rotating the valve disc, e.g.during or to change a flow path through the valve unit, the valve disc is axially adjusted and / or moved. After or during the axial adjustment and / or movement, the seal of the valve disc may no longer be pressed as strongly, or not at all, onto the other valve disc and / or the housing. After or during the axial adjustment and / or movement, the compressive force of the seal of the valve disc on the other valve disc and / or the housing may be reduced or eliminated. After the axial adjustment and / or movement, the valve disc can be or be rotated into a certain position. After the rotation of the valve disc, the valve disc can again be axially adjusted and / or moved. The axial movement and / or adjustment after the rotation can be opposite to the axial movement and / or adjustment before the rotation.After or during the axial adjustment and / or movement, a pressure force of the seal of the valve disc on the other valve disc and / or on the housing can be increased again, for example in order to increase the sealing effect of the seal.

[0077] By means of the axial adjustment and / or movement, a distance of the valve disc in the axial direction to the further valve disc and / or to the housing of the valve unit can be adjusted and / or varied.

[0078] Accordingly, it can be provided that the additional valve disc is or will be adjusted axially when it is or is being moved. It can be provided that the additional valve disc is or will be adjusted axially when the additional valve disc rotates. This means, for example, that the seal of the additional valve disc does not come into contact with the valve disc and / or the housing of the valve unit when the additional valve disc rotates. This means, for example, that the seal of the additional valve disc can be or will be pressed less strongly onto the valve disc and / or the housing of the valve unit when the additional valve disc rotates. This can make rotation of the additional valve disc easier and / or prevent or at least reduce wear on the seal due to friction.

[0079] In some embodiments, for example, it can be provided that before the further valve disc is rotated, e.g. during or to change a flow path through the valve unit, the further valve disc is axially adjusted and / or moved. After or during the axial adjustment and / or movement, the seal of the further valve disc can no longer be pressed as strongly, or not at all, onto the valve disc and / or the housing. After or during the axial adjustment and / or movement, a compressive force of the seal of the further valve disc on the valve disc and / or the housing can be reduced or eliminated. After the axial adjustment and / or movement, the further valve disc can be or can be rotated into a specific position.

[0138] Figure 1a shows a partially sectioned top view of a valve disc 20. The valve disc 20 has a sealing arrangement 60. The sealing arrangement comprises a base element 61 and a seal 63. An adhesion promoter (not shown in Figure 1a) is arranged between the base element 61 and the seal 63.

[0139] The valve disc 20 may have one, several or all features of a valve disc 20 according to the disclosure.

[0140] The valve disc has a valve disc line system 21. The valve disc line system 21 comprises one or more flow lines 23. The flow lines 23 can extend through the valve disc 20. The valve disc line system 21 comprises one or more flow openings 24. The flow openings 24 are arranged on the outer surface of the valve disc 20. Fluid can enter the valve disc line system 21 and / or a flow line 23 through a corresponding flow opening 24 and exit the valve disc line system 21 and / or the flow line 23 through another corresponding flow opening 24. A flow line 23 can, for example, be fluidically connected to two corresponding flow openings 24 and / or have two corresponding flow openings 24. It can be provided that at least two, several or all of the flow lines 23 are not fluidically connected to one another.The sealing arrangement 60 and / or the base element 61 protrudes from an outer surface of the valve disc 20. For example, the base element 61 and / or the sealing arrangement 60 can extend from a flat side of the valve disc 20. The sealing arrangement 60 can be arranged such that it can seal a flow opening 24 of a valve disc conduit system 21. The sealing arrangement 60 can be arranged such that it at least partially or completely encloses a flow opening 24.

[0141] The base element 61 can be formed integrally with the valve disc 20. The base element 61 can be formed integrally with the outer surface. The base element 61 can be formed integrally with the valve disc 20. The base element 61 can be formed integrally with a valve disc body of the valve disc 20. However, it can also be provided that the base element 61 is not formed integrally.

[0142] The sealing arrangement 60 is arranged on the outer surface of the valve disk 20 such that it does not cover any of the flow openings 24 on the outer surface. The valve disk line system 21 and / or a flow line 23 in the valve disk can run beneath the sealing arrangement 60, wherein material of the valve disk 20 can be present and / or arranged between the valve disk line system 21 and / or the flow line 23 and the sealing arrangement 60. In other words, the sealing arrangement 60 and the valve disk line system 21, and / or the sealing arrangement 60 and a flow line 23, can intersect without overlapping on the outer surface. In the exemplary embodiment shown in Figure 1a, the sealing arrangement 60, for example, crosses two flow lines 23 running in the valve disk 20, as shown by the partial section, without covering their flow openings 24 on the outer surface.

[0143] The sealing arrangement 60 and / or the base element 61 can, for example, have a web, as shown merely by way of example in Figure 1a. The shape of the sealing arrangement 60 and / or the base element 61, in particular its spatial extension and / or spatial dimension, is not limited thereto, however. The sealing arrangement 60 and / or the base element 61 can be designed such that one or more flow openings 24 can be sealed against leakage. Figure 1b shows an exemplary side view of an exemplary sealing arrangement 60. The sealing arrangement 60 has a base element 61 and a seal 63. An adhesion promoter 62 is arranged between the base element 61 and the seal 63. The adhesion promoter 62 can ensure and / or enable a good connection between the base element 61 and the seal 63. The area of ​​the base element 61 can be larger than the area of ​​the seal 63, e.g., in a plan view (e.g., in the view of Fig.la and / or perpendicular to figure ib).

[0144] Figure 2a shows an exemplary sealing arrangement 60 that completely encloses a flow opening 24 on an outer surface of a valve disc 20. The sealing arrangement 60, and / or the base element 61, can be circular or annular, for example, but is not limited thereto. The sealing arrangement 60 can be arranged on or at a side surface of the valve disc 20, for example, but is not limited thereto.

[0145] Figure 2b shows another exemplary arrangement of a sealing arrangement 60 for preventing leakage of a flow opening 24. The sealing arrangement can extend over the edge of the valve disc to the top and / or bottom of the valve disc 20, or beyond into or onto the top and / or bottom.

[0146] Figure 2c shows further exemplary arrangements of sealing arrangements 60 for preventing leakage from flow openings 24. The sealing arrangement 60 shown in Figure 2c at the lower edge of the valve disc can, for example, correspond to the continuation of a sealing arrangement 60 arranged as in Figure 2b, e.g., a sealing arrangement 60 extending from one side surface into the flat side of the valve disc 20. However, the shape of the sealing arrangements 60 is merely exemplary and not limited to those shown in the figures.

[0147] Figure 3 shows an exemplary flow diagram of an exemplary method 1000 for producing a valve disc 20.

[0148] In a step 1010, a valve disc body is provided. The valve disc body has a valve disc line system 21 with flow openings 24 arranged on an outer surface of the valve disc body. The valve disc body has a base element 61 protruding from the outer surface. The base element 61 is arranged such that it does not overlap with the flow openings 24 on the outer surface. In some embodiments, the base element 61 can be formed during or before the provision of the valve disc body. Providing the valve disc body can, for example, comprise forming the base element 61. Forming the base element 61 can comprise machining the valve disc body to form the base element 61. For example, the valve disc body can be mechanically machined, e.g., by machining, to form the base element 61. For example, the valve disc body can be milled to form the base element 61.Alternatively or additionally, the base element 61 can be formed on or with the valve disc body by additive manufacturing. For example, the base element 61 can be formed on or with the valve disc body by deposition welding, e.g., by laser deposition welding. For example, the base element 61 can be formed on or with the valve disc body by a D-printing process.

[0149] It can be provided that the base element 61 is or will be formed integrally with the valve disc body.

[0150] In a step 1020, an adhesion promoter 62 is applied to the base element 61. The application of the adhesion promoter 62 may comprise silanization. The adhesion promoter 62 may be or comprise a silane. Alternatively or additionally, the adhesion promoter 62 may be or comprise an organic polymer.

[0151] Because the base element 61 protrudes from the outer surface, the bonding agent 62 can be reliably, securely, and / or precisely positioned. Because the base element 61 protrudes from the outer surface, the alignment of the bonding agent 62 during application can be simplified and / or facilitated.

[0152] A silane can be or comprise a chemical compound that combines a silicon atom with hydrogen atoms and / or organic radicals (e.g. alkyl or aryl groups).

[0153] The adhesion promoter 62 can serve to improve and / or provide the bond of a seal 63 or an elastomer material to the base element 61. The silane can be or comprise, for example, aminosilane, vinyltrichlorosilane, octylchlorosilane, tetraethylorthosilane, or the like.

[0154] It may be provided that the base element 61 can be cleaned and / or roughened before the adhesion promoter 62 is applied. In some embodiments, the cleaning and / or roughening can comprise a chemical etching process. In some embodiments, the cleaning and / or roughening can comprise a mechanical process, for example, grinding and / or polishing. In some embodiments, the cleaning and / or roughening can comprise chemical mechanical planarization (CMP).

[0155] Before applying the adhesion promoter 62, a plasma treatment and / or anodization of the base element 61 can be carried out. The plasma treatment can, for example, be used to clean the outer surface and / or the base element 61. The plasma treatment can, for example, be used to apply a coating to the outer surface and / or the base element 61, which can increase the hardness and / or the corrosion resistance of the outer surface and / or the base element. The plasma treatment can, for example, increase the surface energy of the outer surface and / or the base element 61. The plasma treatment can, for example, activate the outer surface and / or the base element 61. The increased surface energy and / or the surface activation can, for example, improve the adhesion of the adhesion promoter and / or the elastomer material. The increased surface energy and / or the surface activation can, for example, improve the adhesion of the adhesion promoter and / or the elastomer material.adhesion and / or wettability of the base element 61 and / or the adhesion promoter 62 can be increased, and / or functional groups (such as -OH, -NH2, -COOH) can be attached to the outer surface and / or the base element 61, which can, for example, make the outer surface and / or the base element 61 more reactive and ready for chemical reactions.

[0156] Applying the adhesive 62 may involve immersing the valve disc body and / or the base element 61 in an adhesion promoter solution, for example, a silane solution. Applying the adhesive 62 may involve spraying the adhesion promoter 62, for example, a silane. Applying the adhesive 62 may involve spreading and / or brushing the base element 61. However, the application of the adhesive 62 is not necessarily limited thereto.

[0157] The adhesion promoter 62 can react with the surface of the base element 61. If the adhesion promoter 62 comprises a silane, it can be provided that the adhesion promoter 62 can create a siloxane bond on or at the base portion.

[0158] In some embodiments, the adhesion promoter 62 may alternatively or additionally be or comprise an adhesive. The adhesion promoter 62 may comprise or comprise an organic polymer. For example, the adhesion promoter 62 may be or comprise a polyurethane, an epoxy resin, a silicone polymer, a silane, a polysulfide, or the like.

[0159] In a step 1030, an elastomer material is arranged over the base element 61. The adhesion promoter 62 is arranged between the elastomer material and the base element 61.

[0160] Because the base element 61 protrudes from the outer surface, the elastomer material can be reliably, securely, and / or precisely placed. Because the base element 61 protrudes from the outer surface, the alignment of the elastomer material during application and / or placement can be simplified and / or facilitated.

[0161] Before arranging the elastomer material and / or after applying the adhesion promoter 62, the adhesion promoter 62 can be dried. Drying can increase the effect of the adhesion promoter 62. Drying can stabilize the adhesion promoter 621. It can be provided that drying can remove residues, e.g., moist residues, that interfere with vulcanization. The adhesion promoter 62 can form a stable layer on the base element 61 upon drying. If the adhesion promoter 62 comprises a silane, the silane can react further upon drying and / or form a stable layer on the base element 61.

[0162] The elastomer material may comprise a not yet vulcanized material, e.g., a rubber material, a rubber material, or the like. The elastomer material may comprise or be, for example, a natural rubber, a synthetic rubber, a fluororubber, a silicone rubber, polychloroprene, acrylonitrile rubber, or the like.

[0163] In a step 1040, the elastomer material is vulcanized so that a seal 63 is formed on the base element 61.

[0164] Vulcanization may comprise mixing the elastomer material with a vulcanizing agent. Alternatively or additionally, the elastomer material may already comprise a vulcanizing agent. The vulcanizing agent may, for example, comprise sulfur or another suitable vulcanizing agent.

[0165] Vulcanization may comprise heating the base member 61 and the elastomer material 63. Vulcanization may comprise heating the adhesion promoter 62. For example, an oven, a vulcanization press, an autoclave, or other suitable device may be used for this purpose. Heating may comprise heating to a temperature of 140°C, or of at least 140°C. Alternatively or additionally, heating may comprise heating to a temperature of 160°C, or of at least 160°C. Alternatively or additionally, heating may comprise heating to a temperature of 180°C, or of at least 180°C. Alternatively or additionally, heating may comprise heating to a temperature of more than 180°C. Alternatively or additionally, heating may comprise heating to a temperature of 250°C, or of up to 250°C. Vulcanization can take place under a pressure of 1 MPa or more than 1 MPa.Alternatively or additionally, vulcanization can be carried out under a pressure of 2 MPa or more than 2 MPa. Alternatively or additionally, vulcanization can be carried out under a pressure of 6 MPa or more than 6 MPa. Alternatively or additionally, vulcanization can be carried out under a pressure of 10 MPa or up to 10 MPa.

[0166] During vulcanization, a chemical reaction can occur that can make the elastomer material elastic and stable. The chemical reaction can comprise a chemical reaction of the vulcanizing agent, e.g. between the vulcanizing agent and rubber. During vulcanization, cross-linking of molecules of the elastomer material can occur. During vulcanization, chemical bonds can be created between molecules of the elastomer material and the adhesion promoter 62 and / or the base element 61. This allows the elastomer material to adhere to the adhesion promoter 62 and / or the base element 61. Vulcanization can comprise vulcanizing the elastomer material onto the base element 61 and / or the adhesive 62. During vulcanization, the elastomer material can form a seal 63. The seal 63 can be or become connected to the adhesion promoter 62 and / or the base element 61.

[0167] The elastomer material may be or comprise a vulcanized elastomer material, and in forming the seal, the elastomer material may be vulcanized again.

[0168] Before applying the adhesion promoter 62 and / or before vulcanizing the elastomer material, a plasma treatment and / or anodization of the base element can be carried out.

[0169] The plasma treatment can, for example, be used to clean the outer surface and / or the base element 61. The plasma treatment can, for example, be used to apply a coating to the outer surface and / or the base element 61, which can increase the hardness and / or the corrosion resistance of the outer surface and / or the base element 61. The plasma treatment can, for example, increase the surface energy of the outer surface and / or the base element 61. The plasma treatment can, for example, activate the outer surface and / or the surface of the base element 61. The increased surface energy and / or the surface activation can, for example, improve the adhesion of the adhesion promoter 61 and / or the elastomer material. The increased surface energy and / or the surface activation can, for example, increase the adhesion and / or wettability of the adhesion promoter 62 and / or the elastomer material, and / or functional groups (such as-OH, -NH2, -COOH) may be applied to the outer surface and / or the base element 61, which may, for example, make the outer surface and / or the base element 61 more reactive and / or ready for chemical reactions.

[0170] Anodization can, for example, form an oxide layer on the outer surface and / or on the base element 61. The anodization and / or the oxide layer can provide corrosion protection and / or serve to increase wear resistance. Alternatively or additionally, the anodization and / or the oxide layer can provide electrical insulation. Alternatively or additionally, the anodization and / or the oxide layer can increase adhesion.

[0171] The sealing arrangement 60 can be configured to be resistant to temperatures of up to 250°C, in particular not to be destroyed or decomposed, and / or to still have a good sealing effect. In some embodiments, the sealing arrangement 60 can be configured to be resistant to temperatures of more than 250°C, in particular not to be destroyed or decomposed, and / or to still have a good sealing effect. Thus, the valve disc and / or the valve unit can be suitable for the flow of fluid at a high temperature.

Even though two valve discs 20, 30 are shown in the figures, the valve unit 10 can have more than two valve discs 20, 30, in particular two or more further valve discs 30. The valve disc 20 has a sealing arrangement not shown in Figures 4, 5a and 5b. The further valve disc 30 can have a sealing arrangement not shown in Figures 4, 5a and 5b. The valve disc 20 can have one, several or all features of a valve disc 20 according to the disclosure. The further valve disc 30 can have one, several or all features of a further valve disc 30 according to the disclosure.

[0174] The sealing arrangement of the valve disc 20 can serve to prevent leakage and / or leakage flow into or out of the valve disc line system 21 of the valve disc 20 when fluid flows through the valve unit 10. The sealing arrangement of the valve disc 20 can serve to prevent leakage and / or leakage flow into or out of one or more flow openings 24 of the valve disc 20 when fluid flows through the valve unit 10.

[0175] If the further valve disc 30 has a sealing arrangement, the sealing arrangement of the further valve disc 30 can serve to prevent leakage and / or leakage flow into or out of a further valve disc line system 31 of the further valve disc 30 when fluid flows through the valve unit 10. If the further valve disc 30 has a sealing arrangement, the sealing arrangement of the further valve disc 30 can serve to prevent leakage and / or leakage flow into or out of one or more flow openings 24 of the further valve disc 30 when fluid flows through the valve unit 10.

[0176] It can be provided that the sealing arrangement of the valve disc 20, in particular the seal 63 of the valve disc 20, can contact the further valve disc 30 and / or a housing of the valve unit 10. In particular, it can be provided that the sealing arrangement of the valve disc 20, in particular the seal 63 of the valve disc 20, contacts the further valve disc 30 and / or the housing of the valve unit 10 when the valve disc 20 and / or the further valve disc 30 is not moving, in particular is in a rest position and / or is not rotated.

[0177] It can be provided that, if the further valve disc 30 has a sealing arrangement, the sealing arrangement of the further valve disc 30, in particular the seal of the further valve disc 30, can contact the valve disc 20 and / or the housing of the valve unit 10. In particular, it can be provided that the sealing arrangement of the further valve disc 30, in particular the seal of the further valve disc 30, contacts the valve disc 20 and / or the housing of the valve unit 10 when the valve disc 20 and / or the further valve disc 30 is not moving, in particular is in a rest position and / or is not rotated.

[0178] In some embodiments, it can be provided that the valve disc 20 is axially adjustable or is adjusted axially when it is moved. It can be provided that the valve disc is adjusted axially when the valve disc rotates. This means, for example, that the seal 63 of the valve disc 20 does not come into contact with the further valve disc 30 and / or the housing of the valve unit 10 when the valve disc 20 rotates. This means, for example, that the seal of the valve disc 20 can be or become pressed less strongly onto the further valve disc 30 and / or the housing of the valve unit 10 when the valve disc 20 rotates. This can make rotation of the valve disc 20 easier and / or prevent or at least reduce wear of the seal 63 due to friction.

[0179] In some embodiments, for example, it can be provided that before the valve disc 20 is rotated, e.g. during or to change a flow path through the valve unit 10, the valve disc 20 is axially adjusted and / or moved. After or during the axial adjustment and / or movement, the seal 63 of the valve disc 20 can no longer be pressed as strongly, or not at all, onto the further valve disc 30 and / or the housing. After or during the axial adjustment and / or movement, a compressive force of the seal 63 of the valve disc 20 on the further valve disc 30 and / or the housing can be reduced or eliminated. After the axial adjustment and / or movement, the valve disc 20 can be or can be rotated into a specific position. After the rotation of the valve disc 20, the valve disc 20 can again be axially adjusted and / or moved.The axial movement and / or adjustment after rotation can be opposite to the axial movement and / or adjustment before rotation. After or during the axial adjustment and / or movement, the compressive force of the seal 63 of the valve disc 20 on the other valve disc 30 and / or the housing can be increased again, for example, to increase the sealing effect of the seal 63.

[0180] By means of the axial adjustment and / or movement, a distance between the valve disc 20 in the axial direction and the further valve disc 30 and / or the housing of the valve unit 10 can be set and / or varied. Accordingly, it can be provided that the further valve disc 30 is or will be axially adjusted when it is or is being moved. It can be provided that the further valve disc is axially adjusted when the further valve disc rotates. This means, for example, that a seal of the further valve disc 30 cannot come into contact with the valve disc 20 and / or the housing of the valve unit 10 when the further valve disc 30 rotates. This means, for example, that the seal of the further valve disc 30 can be or will be pressed less strongly onto the valve disc 20 and / or the housing of the valve unit 10 when the further valve disc 30 rotates.This can facilitate the rotation of the further valve disc 30 and / or prevent or at least reduce wear of the seal due to friction.

[0181] In some embodiments, for example, it can be provided that before the further valve disc 30 is rotated, e.g. during or to change a flow path through the valve unit 10, the further valve disc 30 is axially adjusted and / or moved. After or during the axial adjustment and / or movement, the seal of the further valve disc 30 can no longer be pressed as strongly, or not at all, onto the valve disc 20 and / or the housing 10. After or during the axial adjustment and / or movement, a compressive force of the seal of the further valve disc 30 on the valve disc 20 and / or the housing can be reduced or eliminated. After the axial adjustment and / or movement, the further valve disc 30 can be or be rotated into a specific position. After the rotation of the further valve disc 30, the further valve disc 30 can in turn be axially adjusted and / or moved.The axial movement and / or adjustment after rotation can be opposite to the axial movement and / or adjustment before rotation. After or during the axial adjustment and / or movement, the compressive force of the seal of the additional valve disc 30 on the valve disc 20 and / or the housing can be increased again, for example, to increase the sealing effect of the seal.

[0182] By means of the axial adjustment and / or movement, a distance of the further valve disc 30 in the axial direction to the valve disc 20 and / or to the housing of the valve unit 10 can be adjusted and / or varied.

[0183] It may be provided that the valve disc 20 can be adjustable and / or movable independently of the further valve disc 30. In some embodiments, it may be provided that both the valve disc 20 and the further valve disc 30 can be or can be axially adjusted. In some embodiments, during or upon a change in a flow path through the valve unit 10, both the valve disc 20 and the further valve disc 30 can be or can be adjusted and / or moved, for example, in a temporally overlapping manner.

[0184] If the valve unit 10 has additional valve discs, these can also be axially adjustable.

The adjusting element can be configured to interact mechanically with the further valve disc 30 upon rotation of the valve disc 20 such that a distance between the valve disc 20 and the further valve disc 30 is varied during said rotation. In this case, a contact pressure of the seal can be varied and / or changed. The distance can be varied perpendicular to the direction of rotation during rotation. For example, the seal 63 of the valve disc 20 can not contact the further valve disc 30 during rotation.

[0187] Alternatively or additionally, the adjusting element can be configured to mechanically interact with the housing of the valve unit 10 upon rotation of the valve disc 20 such that the distance between the valve disc 20 and the housing varies during said rotation. The distance can be varied perpendicular to the direction of rotation and / or in a plane of the direction of rotation during rotation. For example, the seal of the valve disc 20 cannot contact the housing during rotation.

[0188] The adjusting element can be designed such that the distance in the first rotational position and the second rotational position of the valve disc 20 and / or the further valve disc 30 is smaller than in at least one other rotational position of the valve disc 20 and / or the further valve disc 30.

[0189] The adjustment element can be ramp-shaped. The further valve disc 30 can have a complementary adjustment element, e.g., a complementary ramp-shaped element.

In some embodiments, the further valve disc 30 can be arranged above the valve disc 20. Alternatively or additionally, it can also be provided that the valve disc 20 can be arranged above at least one further valve disc 30. If the valve unit has more than one further valve disc 30, it can be provided that at least one further valve disc 30 can be arranged above at least one further valve disc 30, for example in the direction of the axis of rotation D.
