Description

[0001] The present invention relates to a modular throttle assembly for a process plant, such as a chemical plant, a power plant, a food processing plant, or the like; a controllable throttle module, in particular one that can be inserted therein, for controlling, in particular for adjusting and / or regulating, one or more fluid profiles and / or fluid flows in the process plant; and a fixed throttle module, in particular one that can be inserted therein, for controlling, in particular for adjusting and / or regulating, one or more fluid profiles and / or fluid flows in the process plant. Furthermore, the invention relates to a method for providing different fluid profiles, in particular fluid characteristics, of a fluid flow, in particular a process fluid flow, by means of a corresponding modular throttle assembly and / or a corresponding controllable throttle module and / or a corresponding fixed throttle module.

[0002] Publication WO 2021 / 071 738 A1 discloses a valve for regulating fluid flow, comprising a housing that defines a fluid inlet and a fluid outlet. A flow control element is located within the housing and is configured to dissipate energy in a fluid flowing from the fluid inlet to the fluid outlet. A valve seat is positioned within the housing and comprises a plurality of vortex generators that create vortices in the fluid as the fluid flows through the valve seat. A piston is located within the housing and is movable relative to it between a closed and an open position. The piston moves away from the valve seat as it moves from the closed position toward the open position, so that the fluid flow through the flow control element and the valve seat increases as the piston moves from the closed to the open position.The piston is designed as a cage valve. The housing is specifically designed and structured to accommodate the piston and the flow control element, which negatively impacts flexibility and compatibility for various applications. The possible and adjustable fluid flow patterns are also limited.

[0003] Several throttle discs are known from US 10,989,329 B2. This patent discloses a device for controlling fluid flow, comprising a body with a central opening extending along a longitudinal axis through it, and a plurality of channels extending from an outer side wall of the body to an inner side wall. At least one first channel can intersect at least one other channel, with the throttle discs arranged around a circumference. However, the specific structure and design make the arrangement incompatible with other valves and complicate the assembly, replacement, and repair of the throttle elements or discs. The fluid flow patterns that can be achieved or adjusted are also limited.

[0004] The same applies to the publication EP 2 825 723 A2, which describes a throttle with a piston or a control piston.

[0005] Document CN 1 15 492 987 A relates to an adjustable combined lamella structure comprising a lamella assembly used to adjust the flow rate of the throttle valve. The lamella assembly includes throttle lamellae with grooves formed in their surfaces and drainage holes extending through the front and back surfaces of the lamellae. The multiple throttle lamellae are stacked sequentially and rotatably mounted in a sleeve on the guide rod.

[0006] The publication DE 31 44 609 A1 relates to a valve with several valve seats arranged one behind the other in the direction of flow, each of which interacts with a movable closing element.

[0007] The German patent application DE 10 2021 120 551 A1 relates to a throttle channel for a throttle body for reducing the fluid pressure at a control valve for installation in a process fluid line of a process plant, such as a chemical plant, a power plant, a brewery or the like, wherein the throttle body is additively formed layer by layer in one direction of construction, and comprises a throttle channel profile extending from an upstream throttle channel inlet to a downstream throttle channel outlet, wherein the throttle channel has a throttle channel cross-section having a gable arc and at least one overhang surface immediately adjoining the gable arc, the overhang angle of which does not exceed an angle threshold of at most 75°, wherein the throttle channel has a throttle channel width transverse to the direction of construction and wherein the gable arc defines an arc width w in the range of 5% to 30% of the throttle channel width B.

[0008] The publication DE 830 142 B concerns a shock absorber for a diaphragm subjected to pressure from liquid or gas, e.g. for diaphragm-controlled valves.

[0009] The object of the present invention is to overcome the disadvantages of the prior art and in particular to provide an improved throttle connection, as well as an improved, in particular usable, adjustable throttle element and / or fixed throttle element, which not only increase the modularity, flexibility and / or compatibility but also have improved flow and / or throttling properties.

[0010] The problem is solved by the features of the independent claims. The dependent claims describe preferred embodiments. Further aspects, advantages, and features become apparent from the dependent claims, the description, and the accompanying drawings.

[0011] The invention relates to a modular throttle inlet for a process engineering plant, such as a chemical plant, a power plant, a food processing plant, or the like, comprising: a housing body for connecting to a process fluid pipeline of the process plant, wherein the housing body has an inlet opening and an outlet opening for a process fluid, wherein the housing body forms a receiving space which is designed for the insertion of different throttle modules, including both adjustable throttle modules, in particular according to one or more of the aspects and / or embodiments of the invention described herein, and fixed throttle modules, in particular according to one or more of the aspects and / or embodiments of the invention described herein, characterized by the fact that The size of the receiving space is matched to the size of the different throttle modules in such a way that the different throttle modules, in a state inserted in the receiving space, are in contact with a wall of the housing body on the outside, in particular in the circumferential direction, essentially completely, and in a sealing manner.

[0012] The invention relates to an adjustable throttle module, in particular for a modular throttle receiver according to one or more of the aspects and / or embodiments of the invention described herein, for controlling, in particular for adjusting and / or regulating, one or more fluid flows and / or fluid currents in a process plant, such as a chemical plant, a power plant, a food processing plant, or the like, comprising: a fluid control body with a substantially cylindrical section, designed for particularly form-complementary engagement with a substantially hollow cylindrical control piston; characterized by the fact that the essentially cylindrical section has at least one elongated recess, in particular a slot, on an outer surface, in particular a circumferential surface, wherein the at least one elongated recess, in particular the slot, extends in the axial direction of the fluid control body.

[0013] The invention relates to a fixed throttle module, in particular for a modular throttle mount according to one or more of the aspects and / or embodiments described herein and / or in particular for, preferably fluidically, connection with an adjustable throttle module according to one or more of the aspects and / or embodiments described herein, for controlling, in particular for adjusting and / or regulating, one or more fluid flows and / or fluid currents of a process plant, such as a chemical plant, a power plant, a food processing plant, or the like, comprising: at least one substantially disc-shaped throttling element comprising at least one throttling channel extending between at least one fluid inlet area and at least one fluid outlet opening, characterized by the fact that the at least one throttle channel is inclined, in particular oblique, and / or angled with respect to a surface, in particular a cross-sectional area, of the at least one substantially disk-shaped throttle element.

[0014] The invention relates to a fixed throttle module, in particular according to one or more of the aspects and / or embodiments described herein and / or in particular for, preferably fluidically, connection with an adjustable throttle module according to one or more of the aspects and / or embodiments described herein, for controlling, in particular for adjusting and / or regulating, one or more fluid flows and / or fluid currents of a process plant, such as a chemical plant, a power plant, a food processing plant, or the like, comprising: at least two essentially disc-shaped throttling elements, which are connected in series, particularly in the flow direction of a process fluid, characterized in that the at least two essentially disc-shaped throttling elements form at least one common fluid flow channel which runs through both of the at least two essentially disc-shaped throttling elements.

[0015] The invention relates to a method for providing different fluid profiles, in particular fluid characteristics, of a fluid flow by means of - a modular throttle receptacle according to one or more of the aspects and / or embodiments of the invention described herein and / or - a controllable throttle module according to one or more of the aspects and / or embodiments of the invention described herein, and / or - a fixed choke module according to one or more of the aspects and / or embodiments of the invention described herein.

[0016] A "throttle receptacle" can be understood to be a body, structure, device and / or part, e.g. a component, that is designed to accommodate several, in particular different and / or substantially identical, throttle modules, for example, adjustable throttle modules and / or fixed throttle modules as described herein.

[0017] The throttle receptacle according to the invention can comprise or be formed by a housing body. The housing body can include an inlet opening or process fluid inlet and an outlet opening or process fluid outlet, for example for a process fluid, as well as a through-opening or process fluid passage arranged between the process fluid inlet and the process fluid outlet. The housing body can also include an actuation opening for inserting an actuating rod and / or a control piston (and / or optionally an actuator). Furthermore, a cover, e.g., a housing cover, can be provided, which is attached or attachable to the housing body, for example for closing and / or covering the actuating opening. The housing cover can have a through-opening, in particular extending in the direction of a stroke axis, for the actuating rod and / or the control piston or the like. The actuating rod orThe control piston can be translationally movable along the stroke axis H, e.g., in the axial direction of the housing body and / or the actuating rod. The control piston can be actuated by means of the actuating rod or a valve rod.

[0018] When this text refers to an essentially "vertical," "axial," or "perpendicular" direction, it may mean a direction that essentially corresponds to the direction of the stroke axis of the control valve and / or the direction of gravity (and vice versa). Similarly, when this text refers to an essentially "horizontal" or "transverse" direction, it may mean a direction that essentially corresponds to a direction perpendicular to the direction of the stroke axis and / or the direction of gravity. Other directions, such as those described above, may be explicitly mentioned.

[0019] Mounting devices, such as flange-like fastening sections, can be provided at both the process fluid inlet and outlet of the housing body for connecting a pipeline for conveying process fluid, in particular a process fluid pipeline, e.g., of the process plant. It is conceivable that the mounting devices can be detachably attached to the process fluid pipeline, e.g., by means of screw connections.

[0020] The throttle body and / or the housing can be a single-piece body made of one or more media- and / or temperature-resistant materials. For example, the throttle body and / or the housing can be a single-piece metal casting or forging, with sections of a machined surface, such as polished and / or coated, for example, painted, powder-coated, chrome-plated, enamelled, electroplated, or the like. It is preferred that the housing defines an interior space, the openings of which are preferably exclusively the process fluid inlet, the process fluid outlet, and the actuating opening. It is conceivable that the housing has further openings to the interior space, for example, openings for inserting sensors or one or more additional process fluid inlets or outlets.

[0021] The housing cover is designed and configured to cover and / or close the actuation opening. In particular, the housing cover may include a mounting section for installing an actuator, especially a pneumatic one, or a yoke, coupling structure, especially a lantern, or the like for supporting an actuator. A corresponding mounting section may also be present on the housing body. Manual, pneumatic-hydraulic, and / or electric actuators may be used.

[0022] The through-opening can be free of sealant for sealing between the housing cover and the actuating rod. The through-opening can be free of guides, such as a plain bearing, a ball bearing, or the like, for the translational guidance of the actuator. The housing cover can be made of a temperature- and / or media-resistant material. It is conceivable that the same material is selected for both the housing body and the housing cover. The housing cover and the housing body can be designed for mounting the housing cover in direct contact. For example, the housing body and the housing cover can have corresponding flange sections for attaching the housing cover to the housing body. A coupling structure, in particular a lantern, can also be provided between them, but this is not mandatory.The housing cover can have a plate-like cover section, which may preferably be designed to completely close the actuating opening of the housing body in the radial direction and in the circumferential direction with respect to the stroke axis, with the exception of the through-opening.

[0023] The inventive aspects and / or embodiments of the throttle device described herein may be suitable, designed, set up and / or configured for a process plant, such as a chemical plant, a power plant, a food processing plant or the like, in particular for adjusting a process fluid flow of the process plant.

[0024] The housing body of the throttle receptacle according to the invention can form a receiving space which is set up, configured and / or designed to receive or insert "different throttle modules".

[0025] The term "different throttle modules" can be understood to mean, for example, that several throttle modules, in particular different and / or essentially identical ones, can be included. For instance, adjustable throttle modules and / or fixed throttle modules as described herein can be included. As an example, it is possible that i) two or more throttle modules, e.g., two or more fixed throttle modules with essentially identical throttle channel profiles or geometries, are included and / or used within the device. Furthermore, it is possible that ii) two or more fixed throttle modules, e.g., with different throttle channel profiles or geometries, are included and / or used within the device. Furthermore, iii) various combinations of adjustable throttle modules with fixed throttle modules, e.g., as described in point i) and / or ii), are also possible.Furthermore, the number of throttle modules can be varied. In other words, the receiving space is dimensioned and / or designed to accommodate a plurality of different or essentially identical throttle modules, in particular the throttle modules described herein. The throttle modules and the throttle receiver described herein can therefore also be understood as a kit, e.g., a throttle receiver kit comprising a plurality of different and / or essentially identical throttle modules according to one or more of the aspects and / or embodiments of the invention described herein.

[0026] The receiving space can be dimensioned such that several throttle modules described herein can be arranged one behind the other, in succession, and / or one above the other, particularly in the direction of the stroke axis or axial direction. The throttle modules can be held in the receiving space, for example, by force-fit and / or form-fit.

[0027] A "modular" choke housing can therefore be understood here to mean that several choke modules, in particular different and / or essentially identical ones, such as the adjustable choke modules and / or fixed choke modules described herein, can be inserted, placed, arranged, or positioned within the housing space. The housing space can, for example, always have the same dimensions; thus, no adaptation, modification, and / or alteration of it is necessary to accommodate the choke modules, in particular the different and / or essentially identical ones. In this way, choke modules can be easily combined, exchanged, installed, removed, and / or changed, and / or combined or assembled as needed. Furthermore, the housing space, in particular its design, dimensions, and / or arrangement, makes it possible to accommodate one or more, for example,To control, monitor, regulate, and / or adjust various fluid flows, jets, and / or streams without, for example, having to adapt or modify the housing body, or without being forced to provide different housing bodies, particularly those with different structural designs, for each application. The throttle receptacle according to the invention, or the housing body and / or the receiving space, thus realizes a modular design that can be compatible with a plurality of throttle elements described herein. This not only saves resources and time during assembly and maintenance but also enables greater flexibility and multiple applications. A control valve equipped, for example, with the modular throttle receptacle according to the invention can be referred to as a modular control valve.

[0028] According to the invention, the size of the receiving space can be matched to the size of the different throttle modules such that, when inserted into the receiving space, the different throttle modules bear against a wall of the housing body, particularly in a sealing manner, on the outside, especially in the circumferential direction. Alternatively or additionally, the different throttle modules can be arranged next to, one below, or one above the other, particularly in the axial direction. Alternatively or additionally, it is possible to insert the different throttle modules individually into the housing body. For example, the different throttle modules can individually bear against the housing body or its wall, particularly in the axial direction.

[0029] A "size" can be understood as a dimension, for example, the width, length, and / or height of the receiving space. The height of the receiving space can be measured in the direction of the stroke axis, i.e., in the axial direction of the housing body. The width of the receiving space can be measured essentially perpendicular to the stroke axis and / or be limited by a wall of the housing body. The receiving space can be rotationally symmetrical, e.g., essentially cylindrical, for example, having an essentially circular cross-section. The receiving space can extend or run essentially in a straight line in the axial direction, i.e., have an essentially constant cross-section. However, other shapes and / or cross-sections are also conceivable.

[0030] The receiving space can be limited, particularly in the axial direction of the housing body or in the direction of the stroke axis, by at least one shoulder, especially an axial stop. The at least one shoulder can be formed in or through a wall of the housing body, e.g., integrally with it, in one piece, or layer by layer. The at least one shoulder can determine and / or define the height of the receiving space, for example, an insertion height of the receiving space for the different throttle modules. For example, the position, arrangement, and / or placement of the at least one shoulder in the axial direction or in the direction of the stroke axis can determine the height of the receiving space and / or how many throttle modules can be inserted or used in it, e.g., one above the other, one below the other, or one after the other.At least one of the steps can also serve as a stop, for example to fix, hold, and / or support the throttle modules in the axial direction. In this way, axial support can be provided for the throttle modules.

[0031] The receiving space can be located, at least partially and / or section by section, in the area of ​​the through-hole or process fluid passage of the housing body, for example, essentially between the process fluid inlet and outlet. The receiving space can be dimensioned and arranged within the housing body such that the process fluid enters the various throttle modules "essentially in the axial direction" or in the direction of the housing body's stroke axis and / or flows through them sequentially. The position and arrangement of the receiving space can ensure that the process fluid flows through the receiving space and any throttle modules arranged within it, essentially in the axial direction or in the direction of the stroke axis. This allows the process fluid to exert an axial force on the throttle modules, which (additionally) fixes them in the axial direction.can press against, for example, at least one step. In this context, "flow in an essentially axial or vertical direction" should not be understood as an absolute, i.e., purely axial or vertical, flow, but rather as an effective flow. This means that the process fluid can, for example, flow within the throttle modules (e.g., in a throttle channel), at least partially / sectionarily also in a radial direction or transversely to the stroke axis (e.g., radial partial flows / flows, for example in the plane, are also conceivable), but overall or effectively in an axial direction through the receiving space or the throttle modules.

[0032] The throttle modules, when inserted into the receiving chamber, can be in contact with a wall of the housing body, particularly in the circumferential direction, essentially completely, and in a substantially sealing manner. "Substantially sealing" means that the process fluid preferably cannot or does not flow between the wall of the housing body and a circumferential surface of one or more throttle modules, particularly those inserted into the receiving chamber. Rather, as mentioned above, the process fluid flows essentially in an axial or vertical direction, or in the direction of the stroke axis, through the receiving chamber, i.e., for example, further inwards in a radial direction, and through the throttle modules that can be arranged therein, for example, through the throttle channels.

[0033] The at least one paragraph can define the insertion height such that the different throttle modules can be inserted into the receiving space to at least 60%, in particular at least 70%, preferably at least 85%. Alternatively or additionally, the different throttle modules can be inserted into the receiving space to a substantially maximum of 85%, substantially at most 70%, preferably at most 60%. This can be understood, for example, to mean that a wall or height of the receiving space is such that a large proportion (e.g., a total height) of the throttle modules can be inserted into it, and, when inserted, only an insignificant, e.g., a percentage, protrudes from the receiving space in the direction of the lifting axis. This ensures, for example, that the throttle modules can be held firmly or securely in the receiving space and / or provides an advantageous fixation.The different throttle modules can be connected in series within the receiving space, in particular one above the other and / or one below the other, and / or arranged sequentially in the direction of fluid flow, for example individually. In other words, the different throttle modules can be arranged adjacent to one another and / or stacked on top of or above each other within the receiving space, for example in such a way that the process fluid can pass through the throttle modules sequentially, particularly in the direction of the stroke axis.

[0034] The throttle receptacle according to the invention, in particular the housing body, can be designed as an angle valve. For example, the inlet opening and the outlet opening can be arranged essentially at right angles to each other. The receiving chamber can be located essentially below a center line of the inlet opening, or be arranged and / or formed there. This ensures that the process fluid enters the receiving chamber essentially in an axial direction.

[0035] According to the invention, an adjustable throttle module, in particular for a modular throttle mount according to one or more of the aspects of the invention and / or embodiments described herein, can be provided for controlling, in particular for adjusting and / or regulating, one or more fluid flows, fluid jets and / or fluid currents, in particular in a process engineering plant, such as a chemical plant, a power plant, a food processing plant, or the like.

[0036] A "controllable throttle module" can be understood as a device, structure, assembly, part, component, element, and / or subassembly that is designed and / or configured to influence and / or change a fluid, in particular a process fluid flow, especially one or more of its parameters, such as volumetric flow rate, flow rate, velocity, and / or pressure. "Controllable" can refer, for example, to the ability to actively make settings / adjustments, meaning that the fluid, in particular the process fluid flow, can be controlled, varied, changed, and / or regulated, for example, as a result of the position or movement of the control rod and / or a control piston. Controllable throttle modules can therefore be capable of providing, adjusting, and / or controlling different fluid profiles, fluid jets, and / or fluid flows, for example.Depending on the position, orientation and / or orientation of the actuating rod or the control piston.

[0037] According to the invention, a fixed throttle module, in particular for a modular throttle mount according to one or more of the aspects and / or embodiments described herein, and / or in particular for, preferably fluidically, connection with an adjustable throttle module according to one or more of the aspects and / or embodiments described herein, can be provided for controlling, in particular for adjusting and / or regulating, one or more fluid flows, fluid jets and / or fluid streams, in particular in a process plant, such as a chemical plant, a power plant, a food processing plant, or the like.

[0038] In contrast to an adjustable throttle module, a fixed throttle module can be understood as a device, structure, assembly, part, component, element, and / or subassembly in which no variable or adjustable setting or adaptation of the fluid, particularly the process fluid flow, is possible, especially of one or more of its parameters, such as volumetric flow rate, flow rate, velocity, and / or pressure, etc. In other words, fixed throttle modules can have a fixed, unchangeable, predetermined, and / or static structure or configuration, such as the profiles and / or geometries of throttle channels, orifice diameters, dimensions, etc. Fixed throttle modules therefore cannot be "adjustable." However, fixed throttle modules can be capable of providing, adjusting, regulating, and / or controlling different fluid profiles, fluid jets, and / or fluid flows, e.g.,compared to a fluid flow pattern and / or fluid flow when no fixed throttle module is used. This can be achieved, for example, by providing i) multiple fixed throttle modules, ii) (structurally) different fixed throttle modules, and / or iii) combinations or numbers of fixed throttle modules.

[0039] The following section will first discuss an example of an adjustable throttle module.

[0040] A controllable throttle module according to the invention can comprise a fluid control body with a substantially cylindrical section. The substantially cylindrical section can be configured and / or arranged for engagement, particularly in a form-complementary manner, with a substantially hollow cylindrical control piston. The substantially cylindrical section can preferably be essentially solid cylindrical. The substantially cylindrical section can have, for example, on an outer surface, in particular a circumferential or lateral surface, at least one elongated recess, in particular a slot, a groove, or a groove. The at least one elongated recess, in particular the slot, can extend in the axial direction of the fluid control body and / or run in this direction, for example, substantially straight. However, other configurations, e.g., curved, stepped, and / or kinked configurations, are also conceivable.The at least one elongated recess, in particular the slot, can extend substantially the entire length of the outer surface, in particular the circumferential or lateral surface, in the axial direction of the fluid control body. The at least one elongated recess, in particular the slot, can have different cross-sections or cross-sectional shapes. A fluid flow, in particular a fluid characteristic curve, can be adjustable via the cross-section of the at least one elongated recess. For example, the at least one elongated recess, in particular the slot, can have a substantially circular cross-section. Other cross-sections are also possible. It is possible that the cross-section changes or varies, for example, in the direction of extension of the at least one elongated recess, in particular the slot, for example, by tapering, for example, in a V-shape. The tapering can be continuous, e.g., gradual or steady; or abrupt, e.g.,initially runs in a largely straight line and only narrows after a certain distance.

[0041] The fluid control element can comprise a substantially disk-shaped section configured to provide a sealing surface or sealing edge for the substantially hollow cylindrical control piston, in particular its end face. For example, the substantially disk-shaped section can be substantially flat and / or planar, or even disc-shaped. The substantially disk-shaped section can be connected to, and in particular adjoin, the substantially cylindrical section; these sections can be manufactured, for example, in one piece and / or layer by layer.The essentially disc-shaped section can have a larger outer diameter than the essentially cylindrical section, for example such that the essentially cylindrical section and the essentially disc-shaped section form a shoulder, in particular a circumferential one, for example a radial shoulder which runs, for example, in the circumferential direction of the fluid control body.

[0042] The at least one elongated recess, in particular the slot, can extend axially through the section of the fluid control body, which is in particular substantially disc-shaped, preferably substantially completely, and in particular define and / or form a fluid passage opening for a process fluid therein. The design, structure and / or construction of the fluid control body is simple and cost-effective to manufacture; in particular, the fluid control body can be designed as a single-piece body made of one or more media- and / or temperature-resistant materials, for example, a metal.

[0043] A controllable throttle module can comprise a substantially hollow cylindrical control piston, which can be designed in a substantially cup-shaped or sleeve-shaped form, e.g., substantially hollow cylindrical, with one side or surface being closed. The substantially hollow cylindrical control piston can be dimensioned and / or designed to engage with the fluid control body, preferably to accommodate it, in particular for controlling or regulating one or more fluid flows and / or fluid currents via the at least one elongated recess, in particular the slot. The dimensions of the substantially hollow cylindrical control piston, in particular the cavity, can therefore be matched to the dimensions of the fluid control body, e.g., in a form complementary manner. The substantially hollow cylindrical control piston, in combination with the fluid control body, can also be referred to as a fluid regulating device, element, or assembly.For example, the essentially hollow cylindrical control piston can be dimensioned and / or designed to enclose, preferably cover, the outside, in particular the circumferential surface or lateral surface, of the essentially cylindrical section, such that the at least one elongated recess, in particular the slot, and / or the fluid passage opening in the essentially disk-shaped section, can be released and / or closed by the control piston, preferably in a controlled manner, in particular at least partially and / or essentially completely.

[0044] For example, the control piston can have a first position in which the at least one elongated recess, in particular the slot, and / or the fluid passage opening in the substantially disk-shaped section is substantially open, for example at least partially / sectionally and / or substantially completely. This can be referred to as the open position or open state. The control piston can have a second position in which the at least one elongated recess, in particular the slot, and / or the fluid passage opening in the substantially disk-shaped section is substantially obstructed, blocked, and / or closed. This can be referred to as the closed position or closed state. By moving the control piston, in particular in the direction of the stroke axis, e.g.Between the first and second positions, different fluid profiles, in particular fluid characteristics, and / or different cross-sections can be set for controlling and / or regulating the process fluid, e.g. actively, or the process fluid flow can also be essentially completely blocked.

[0045] The essentially hollow cylindrical control piston can have an end face / closing surface, particularly at its end (e.g., viewed in the direction of the stroke axis), such as a sealing surface or sealing edge, which, especially in a closed state of the controllable throttle module, rests against the essentially disk-shaped section of the fluid control body, particularly in a sealing manner, for example, against an essentially flat, planar, and / or shallow surface formed there, such as a seat / sealing surface. The essentially disk-shaped section, particularly the seat, can form a contour (e.g., a seat contour and / or a sealing contour or sealing edge) with the sealing surface, particularly at its end, which is complementary in shape or parallel to the plane and can serve for closing (e.g., closed position or closed state). Depending on the fluid and / or degree of sealing, or...However, this contour can also be designed or formed differently depending on the sealing class.

[0046] The adjustable throttle module can include a clamping element, in particular a substantially sleeve-shaped one. A "substantially sleeve-shaped clamping element" is understood to be a body, element, part, component, and / or structure that is essentially cylindrical, in particular hollow cylindrical. The clamping element, in particular a substantially sleeve-shaped one, can be formed in one piece and / or manufactured layer by layer, for example, from metal, e.g., from the same material as the housing body and / or the fluid control element. The clamping element, in particular a substantially sleeve-shaped one, can be configured, in particular in the assembled state: - to fix the fluid control body, in particular the essentially disc-shaped section, in the axial direction of the fluid control body, in particular by pressing, clamping and / or clamping it; In particular, the essentially sleeve-shaped clamping element may also have an end face, e.g. in the axial direction, which can bear against the essentially disc-shaped section, in particular in a sealing manner. This can provide additional axial fixing and / or clamping for the fluid control body and / or, if applicable, further throttle modules; and / or - to accommodate, surround and / or enclose the essentially hollow cylindrical control piston, and / or to center it in the radial direction of the fluid control body, preferably on the circumference or in the circumferential direction of the essentially hollow cylindrical control piston; This can prevent and / or minimize a danger or risk of, for example, radial deflection, deviation and / or buckling of the control piston (e.g. with respect to a stroke axis), especially at high process pressures.

[0047] The clamping element, which is essentially sleeve-shaped, can include at least one opening. This opening can be designed like a window or in a window-like manner in an outer wall or on the outer circumference of the essentially sleeve-shaped clamping element. It is also possible to provide several openings, for example, with essentially identical dimensions (e.g., length, width, height), which can be arranged, for example, in a circumferentially uniform manner, e.g., at uniform intervals. However, different and / or varying distances are also conceivable. A number of the openings can be aligned with or correspond to a number of the elongated recesses of the fluid control body.The at least one opening can be dimensioned and / or arranged, particularly in the assembled state, such that the at least one elongated recess, in particular the slot, of the fluid control body is at least partially / sectionarily released. The at least one opening can be at least partially / sectionarily released both in the closed position or closed state (e.g., second position) and in the open position or open state (e.g., first position). In other words, the clamping element, which is in particular substantially sleeve-shaped, can serve solely for axial / radial clamping or centering, whereby the at least one elongated recess, in particular the slot, of the fluid control body is released or closed by the substantially hollow cylindrical control piston.

[0048] In a first embodiment, a fixed throttle module is provided, in particular for a modular throttle mounting according to one or more of the aspects and / or embodiments of the invention described herein, and / or in particular for, preferably fluidically, connection with an adjustable throttle module according to one or more of the aspects and / or embodiments of the invention described herein, for controlling, in particular for adjusting and / or regulating, one or more fluid profiles and / or fluid flows, in particular in a process engineering plant, such as a chemical plant, a power plant, a food processing plant, or the like.

[0049] The fixed throttle module according to the invention can comprise at least one substantially disc-shaped throttle element, which includes at least one throttle channel, for example formed therein. The at least one throttle channel can extend between at least one fluid inlet area and at least one fluid outlet opening.

[0050] A "throttling channel" can be defined as a channel, passage, and / or passageway that has a specific geometry (e.g., course, shape, cross-section, orientation, inclination, direction, etc.) and / or specific dimensions and is designed to guide, direct, and / or control a fluid, particularly a process fluid, or to influence the fluid as it passes through the throttling channel, for example, to regulate the flow rate, such as slowing it down, throttling it, and / or reducing it. In particular, one or more parameters of the fluid, such as volumetric flow rate, flow rate, velocity, and / or pressure, etc., can be influenced or changed by a throttling channel.

[0051] A "fluid inlet area" can be understood as a section, area, and / or location or region where a fluid can enter, but where the fluid cannot (e.g., completely) penetrate or exit the throttling element, but is instead directed, for example, radially or in a plane. A fluid inlet area can, for example, be a recess, particularly a groove, with a depth less than the thickness of the essentially disc-shaped throttling element. A "fluid outlet opening," on the other hand, can be understood as a section, area, and / or location or region where the fluid can exit or leave the throttling element. The at least one fluid outlet opening can be designed as a through-hole, i.e., it can, for example, essentially completely penetrate the throttling element.

[0052] According to the invention, the at least one throttle channel can be inclined, in particular oblique, and / or angled with respect to a surface, in particular a cross-sectional area, of the at least one substantially disk-shaped throttle element. In particular, the at least one throttle channel can be inclined, in particular oblique, and / or angled with respect to the, for example, flat, planar, and / or planar surface or top surface of the substantially disk-shaped throttle element. For example, the at least one throttle channel can be designed as a depression or recess, in particular as a groove or channel, wherein the depth of the at least one throttle channel can change or vary. For example, the depth of the at least one throttle channel can increase from the at least one fluid inlet area to the at least one fluid outlet opening, for example continuously, steadily, and / or gradually.Abrupt changes in the form of steps are also conceivable. This can create a kind of self-cleaning effect, even when the valve is closed, because the fluid, especially the process fluid, can flow out through the slope, angle, and / or inclination, carrying impurities with it. The at least one throttle channel can, for example, run at least at an angle of approximately 2°, 3°, 5°, 7°, 10°, 20°, 25°, 30°, 35°, 40°, 45°, or even more than 45° (e.g., 50°, 60°, 75°) with respect to the surface, especially the cross-sectional area, of the at least one substantially disc-shaped throttle element. The angle, or angular value, of the at least one throttle channel can, for example, depend on the thickness of the substantially disc-shaped element; for example, a greater thickness allows for a larger angle or inclination to be selected and / or provided.

[0053] In a second embodiment, which can be combined with one or more of the aspects and / or embodiments of the invention described herein, a fixed throttle module is provided, in particular for a modular throttle receptacle according to one or more of the aspects and / or embodiments of the invention described herein, and / or in particular for, preferably fluidically, connecting it to an adjustable throttle module according to one or more of the aspects and / or embodiments of the invention described herein, for controlling, in particular for adjusting and / or regulating, one or more fluid profiles and / or fluid flows, in particular in a process plant, such as a chemical plant, a power plant, a food processing plant, or the like.

[0054] The fixed throttle module can comprise at least two essentially disc-shaped throttle elements, which can be arranged in series, one after the other, and / or one above the other or stacked, particularly in the flow direction of a process fluid and / or in the direction of the stroke axis. The at least two essentially disc-shaped throttle elements can form at least one common fluid flow channel. The at least one common fluid flow channel can extend through both of the at least two essentially disc-shaped throttle elements.A "common fluid flow channel" can be understood as a channel, passage, and / or passage that connects a channel of a first, comprising at least two essentially disc-shaped throttling elements, with a channel of a second, comprising at least two essentially disc-shaped throttling elements, particularly fluidically, such that, for example, the fluid can pass through and / or penetrate the at least two essentially disc-shaped throttling elements via the first and second, i.e., the common fluid flow channel. The idea behind a common fluid flow channel is that the essentially disc-shaped throttling elements can cooperate or work together to, for example, influence the flow of the fluid. This can be achieved by changes, e.g., in position, orientation, or the like, for example, by rotation or turning, and / or by selecting / combining specific orBy using different, essentially disc-shaped throttling elements and / or a number of them, the common fluid flow channel can be changed, modified and / or adapted, which in turn changes the flow rate.

[0055] The fixed throttle or the essentially disc-shaped throttle elements can, for example, be inserted, placed, and / or received in the receiving space of the throttle housing, e.g., one above the other. The essentially disc-shaped throttle elements can thus be easily combined, exchanged, and / or installed / removed, changed, and / or, e.g., combined and assembled as needed / required, to form, for example, various shared fluid flow channels. It is also possible, e.g., after installation or assembly, to change the alignment / orientation of the at least two essentially disc-shaped throttle elements relative to each other, e.g., by rotating them, in order to influence or modify the shared fluid flow channel. Thus, one or more, e.g.,Various fluid flows and / or fluid currents can be controlled, monitored, regulated and / or adjusted, thereby enabling the fixed throttle according to the invention to achieve a modular design.

[0056] The at least two essentially disc-shaped throttle elements can be essentially identical in design, or they can differ, for example, with regard to a geometric design, such as one or more throttle channels, and / or dimensions (e.g., thickness) and / or material. For example, the at least two essentially disc-shaped throttle elements can each have different throttle channels that differ from one another in particular in their course, orientation, shape, inclination, direction, cross-section, and / or size or dimension (e.g., length, width, height).

[0057] The common fluid flow channel can be configured to guide the process fluid sequentially through the at least two essentially disc-shaped throttling elements, wherein, in particular, the common fluid flow channel guides the process fluid essentially vertically or axially through the at least two throttling elements. As already mentioned, "essentially axial or vertical" is not to be understood as an absolute, i.e., purely axial or vertical, flow, but rather as an effective flow; that is, the process fluid can, for example, within the at least two essentially disc-shaped throttling elements (for example, in a throttling channel), also flow at least partially / sectionwise in a radial direction or transversely to the stroke axis (e.g., radial throttling elements are also possible).Partial flows / flows (for example, conceivable in the plane), but overall or effectively in axial or vertical direction through the at least two essentially disc-shaped throttling elements.

[0058] The at least two essentially disc-shaped throttle elements can each comprise at least one throttle channel; for example, a first essentially disc-shaped throttle element can form a first throttle channel and a second essentially disc-shaped throttle element can form a second throttle channel. As already mentioned, the first and second throttle channels can be essentially identical or differ as described above, with reference to the preceding explanations in this regard. The first and / or second throttle channel can each extend between at least one fluid inlet area and at least one fluid outlet opening.The fluid outlet opening of a throttle channel of one of the at least two substantially disc-shaped throttle elements (for example, a fluid outlet opening of the first throttle channel of the first substantially disc-shaped throttle element) can be connected, coupled, and / or aligned with the fluid inlet region of a throttle channel of a second of the at least two substantially disc-shaped throttle elements (for example, a fluid inlet region of the second throttle channel of the second substantially disc-shaped throttle element), particularly fluidically. For example, the first and second substantially disc-shaped throttle elements can be arranged and / or aligned with each other such that the fluid outlet opening of the first throttle channel is located directly above the fluid inlet region of the second throttle channel, but not, for example, above the fluid outlet opening of the second throttle channel.In this way, the fluid is forced to first penetrate (e.g., essentially completely) the fluid inlet area or the second throttle channel before reaching the fluid outlet opening of the second, essentially disc-shaped throttle element. As mentioned, this allows one or more fluid paths and / or flows to be advantageously controlled, adjusted, and / or regulated.

[0059] The invention relates to a method for providing different fluid profiles, in particular fluid characteristics, of a fluid flow by means of - a modular throttle receptacle according to one or more of the aspects and / or embodiments of the invention described herein and / or - a controllable throttle module according to one or more of the aspects and / or embodiments of the invention described herein, and / or - a fixed choke module according to one or more of the aspects and / or embodiments of the invention described herein.

[0060] The different fluid profiles, especially fluid characteristics, can be determined by Varying a geometric design, in particular a cross-section and / or a shape, which has at least one elongated recess, in particular a slot, and / or Controlling, in particular adjusting and / or regulating, a stroke of the essentially hollow cylindrical control piston, be provided.

[0061] Different fluid flow patterns, particularly fluid characteristics, can be achieved by varying or combining different throttling modules, e.g., with regard to their number and design. In particular, these can be achieved by varying the geometric design, especially the shape, orientation, or inclination of the respective throttling channels of the at least two essentially disc-shaped throttling elements. It is also possible to change the orientation of the at least two essentially disc-shaped throttling elements relative to each other, e.g., by rotating them, in order to influence and / or achieve different fluid flow patterns, particularly fluid characteristics.

[0062] Furthermore, the method can control, in particular adjust, a damping of the fluid flow by varying a number and / or a design, in particular a structure or geometric design, for example of the throttle channels, as mentioned above, of the at least two essentially disc-shaped throttle elements.

[0064] The invention will now be explained in more detail with reference to embodiments shown in the drawings, wherein in all drawings essentially functionally identical elements have the same reference numerals.

[0065] The drawings are schematic and not to scale.

For the sake of simplicity, identical reference numerals are used to identify identical elements that are common to all drawings. It is intended that elements and features of one embodiment may be advantageously incorporated into other embodiments without further mention.

[0066] Each embodiment serves to illustrate the disclosure and should not be understood as limiting the disclosure. Furthermore, features presented or described as part of one embodiment may be used in conjunction with other embodiments to create a further embodiment. It is intended that the description includes such modifications and variations.

[0067] Fig. Figures 1A-D show a fluid control element 100 of an adjustable throttle module according to an exemplary embodiment. An adjustable throttle module is used, for example, in the Fig. 3A-D and 4A-B are described in more detail. Fig. 1A is a perspective view of the fluid control body 100 and Fig. 1B a top view of the fluid control body 100. Fig. 1C is a side view of the fluid control body 100 and Fig. 1D a section view through section AA from Fig. 1C.

[0068] As in the Fig. As can be seen in Figures 1A-D, the fluid control body 100 can comprise a substantially cylindrical section 102. The substantially cylindrical section 102 can have, for example on an outer surface 104, in particular a circumferential surface or lateral surface of the substantially cylindrical section 102, at least one elongated recess 106, in particular a slot, a groove or a slot. In the Fig. Figures 1A-D show in particular two essentially elongated recesses 106 which are essentially opposite each other, whereby more or fewer may also be provided in the fluid control body 100.

[0069] The at least one elongated recess 106 can be oriented in the axial direction, or in the direction of the stroke axis H (szB Fig. 4A / B), of the fluid control body 100 extend and / or run in this direction, for example essentially straight, as at section AA in Fig. 1C can be seen. However, other configurations, e.g., curved, stepped, and / or kinked configurations, are also conceivable. The at least one elongated recess 106, in particular the slot, can extend substantially completely over the outer surface 104, in particular the circumferential or lateral surface, in the axial direction of the fluid control body 100. As in Fig. As can be clearly seen in Figure 1C, the at least one elongated recess 106, in particular the slot, has a cross-section that changes or varies, for example, in the direction of extension of the at least one elongated recess 106, i.e., it tapers, for example, in a V-shape. The essentially elongated recess 106 can, for example, taper in the direction of the essentially disk-shaped section 108. Such a cross-section and / or the arrangement of the recess 106 along the outer surface 104 can provide advantageous flow and throttling characteristics, enabling the low-noise and low-stress reduction of high pressures and the safe and reliable throttling, control, adjustment, and / or regulation of demanding process fluids.

[0070] The fluid control body 100, as in the Fig. As shown in Figures 1A-D, it can comprise a substantially disc-shaped section 108 which is designed to form a sealing surface or sealing edge (e.g., seat or sealing surface 380, in particular in Fig. 3A / C) for an essentially hollow cylindrical control piston (see control piston 320 e.g. in Fig. 3A, 3C and 4A-4B), in particular its end face (see closure surface 370 in particular) Fig. 3C), to provide. As in Fig. As shown in Figures 1A-D, the substantially disc-shaped section 108 can be substantially flat, planar, and / or planar, for example, plate-like. The substantially disc-shaped section 108 can be connected to the substantially cylindrical section 102. The section shown in the Fig. The fluid control body 100 shown in Figures 1A-D, i.e., the essentially cylindrical section 102 and the essentially disc-shaped section 108, can be manufactured, for example, from a single piece and / or layer by layer, e.g., from metal, and / or, for example, by means of a 3D printing process. As, for example, in Fig. As can be seen in Figure 1B, the essentially disc-shaped section 108 can have a larger outer diameter d1 than the essentially cylindrical section 102 (see diameter d2). The ratio between d1 and d2 can be such, for example, that the essentially cylindrical section 102 and the essentially disc-shaped section 108 form a step, particularly a circumferential one, for example a radial step, which runs, for example, in the circumferential direction of the fluid control body 100, see, for example, the step 109 in Fig. 1B. The ratio between d1 and d2 can also be chosen such that the values ​​in the Fig. 3A / C recognizable seating or sealing surface 380 (or paragraph 109) of a sufficient size for the sealing surface 370 (see Fig. 3C) of the control piston 320.

[0071] As in average AA of the Fig. To be recognized in 1D, the at least one elongated recess 106, in particular the slot, can extend in the axial direction of the fluid control body 100 through the, in particular substantially disc-shaped, section 108, preferably substantially completely, and in particular a fluid passage opening 110 (szB) therein. Fig. 1B and Fig. 1D) define and / or train for a process fluid, thereby providing advantageous flow and throttling properties.

[0072] Fig. Figures 2A-D show a fluid control body 200 of a controllable throttle module according to an embodiment. Fig. 2A is a perspective view of the fluid control body 200 and Fig. 2B a top view of the fluid control body 200. Fig. 2C is a section view through section AA from Fig. 2B and Fig. 2D is a side view of the fluid control body 200.

[0073] The basic structure of the fluid control body 200 in the Fig. 2A-D is essentially identical to the fluid control body 100 of the Fig. 1A-D, so that reference can be made to the previous statements in this regard, whereby reference can be made to the Fig. 2A-D, correspondingly adapted reference symbols are used. The fluid control body 200 of the Fig. However, 2A-D differs in the cross-section of the at least one elongated recess 206, in particular the slot and / or the fluid passage opening 210. As in the Fig. As can be seen in 2A-D, the at least one elongated recess 206, in particular the slot and / or the fluid passage opening 210, has a substantially round cross-section that does not include a taper. It has been shown that even with the one in the Fig. The cross-section shown in 2A-D and / or the arrangement of the recess 106 along the outer surface 104 also provide advantageous flow and throttling properties, with which high pressures can be reduced with low noise and stress, and demanding process fluids can be throttled or controlled, adjusted and / or regulated safely and reliably.

[0074] Fig. 3A-D shows an assembly 300, which includes an adjustable throttle module with a fluid control element, for example a fluid control element 100 as in the Fig. 1A-D shown (where it is clear that alternatively the fluid control body 200 can also be used as in the Fig. 2A-D shown, which can be used), as well as a control piston 320, which is attached and / or fastened to an exemplary actuating rod 325, and a clamping sleeve, as well as a fixed throttle module 340, which comprises three exemplary substantially disc-shaped throttle elements 350A-C, in particular throttle discs. In other words, the Fig. Figures 3A-D show a combination of an adjustable throttle module and a fixed throttle module comprising several throttle elements, in particular throttle discs. It should be noted that this configuration / arrangement is only exemplary; that is, fewer throttle discs 350A-C can also be used (e.g., only one), or one or more of the throttle discs 600-800 can be used, as in the following examples: Fig. 6A-D, 7A-D and Fig. 8A-D can be shown, used, assembled and / or combined. Furthermore, it should be clear that, for example, only one of the two, i.e., exclusively the adjustable throttle module (see e.g. Fig. 5B), e.g. with fluid control body 100 / 200, control piston 320 and clamping sleeve, or exclusively the fixed throttle module (see e.g. Fig. 5A), e.g. with one or more 350A-C and / or 600-800 choke elements, as e.g. in the Fig. 6A-D, 7A-D and Fig. 8A-D shown, can be used.

[0075] As in Fig. As can best be seen in Figure 3C, the controllable throttle module can comprise a hollow cylindrical control piston 320, which can be designed in a substantially cup-shaped or sleeve-shaped form, e.g., substantially hollow cylindrical, with one side or surface being closed. The substantially hollow cylindrical control piston 320 can be dimensioned and / or designed to engage with the fluid control body 100, preferably to accommodate it, in particular for controlling or regulating one or more fluid flows and / or fluid flows through the at least one elongated recess 106, in particular the slot, for example by controlled opening / closing, for example, in particular by translational movement along the stroke axis H.

[0076] As in the average of Fig. As can be seen from section 3C, the dimensions of the essentially hollow cylindrical control piston 320, in particular the cavity 322, can be adapted to the dimensions of the fluid control body 100, in particular the essentially cylindrical section 102, e.g., be designed / configured to be complementary in shape. For example, the essentially hollow cylindrical control piston 320 can be dimensioned and / or designed to enclose the outer surface 104, in particular the circumferential surface or lateral surface, of the essentially cylindrical section 102, preferably to enclose, preferably to cover, orto cover, so that the at least one elongated recess 106 / 206, in particular the slot, and / or the fluid passage opening 110 in the substantially disc-shaped section 108, can be released and / or closed by the control piston 320, preferably controlled, in particular at least partially and / or substantially completely, for example by a movement of the control piston along the stroke axis H, in particular translationally (see point 360 from . Fig. 3A / 3C where the control piston encloses / surrounds the circumferential surface and the recess 106). By moving the control piston 320, particularly in the direction of the stroke axis H, e.g. between a first position (cf. e.g. open position in Fig. 4A) and second position (cf. e.g. closed position in Fig. 4B), in particular including partial positions in between, different fluid profiles, in particular fluid characteristics, and / or different cross-sections for controlling and / or regulating the process fluid, e.g. actively, can be set, or the process fluid flow can also be essentially completely blocked.

[0077] The essentially hollow cylindrical control piston 320 can have a sealing surface 370, in particular at its end face (e.g. viewed in the direction of the stroke axis), e.g. a sealing surface (cf. Fig. 3C), which, in particular in a closed state, rests against the substantially disc-shaped section 108 of the fluid control body 100, in particular sealingly, for example against a substantially flat, planar and / or planar surface formed there, for example a seat surface or sealing surface 380 (cf. Fig. 3C). The essentially disc-shaped section 108, in particular the sealing surface 380, can form a contour 395 with the sealing surface, in particular the end face, which is in particular complementary in shape or parallel to the plane (e.g. a seat contour and / or a sealing contour; as best shown in the Fig. 4B to recognize) form, which are used to close (e.g. closed position or closed state of the Fig. 4B). Depending on the fluid and / or degree of sealing or sealing class, this contour 395 can also be designed or formed differently.

[0078] The adjustable throttle module can include a clamping element 330, in particular a substantially sleeve-shaped one, which, as e.g. in Fig. 3A / 3C shows that the clamping element 330 is essentially cylindrical, in particular hollow cylindrical, for example with a rotationally symmetrical or essentially circular cavity 322. The clamping element 330, in particular essentially sleeve-shaped, can be configured, in particular in the assembled state: - to fix the fluid control body 100, in particular the essentially disc-shaped section 108, in the axial direction of the fluid control body 100 or in the direction of the stroke axis H, in particular by pressing, clamping and / or clamping it; In particular, for example in the axial direction, an end face can be provided on the clamping element 330 which can bear against the seat surface or sealing surface 380 of the essentially disc-shaped section 108 and / or exert a force on it. This can, for example, provide additional axial fixing and / or clamping for the fluid control body 100 and / or, if applicable, also the further throttle modules 350A-C; and / or - to accommodate, surround and / or enclose the essentially hollow cylindrical control piston 320, and / or to center it in the radial direction of the fluid control body 100, preferably on the circumference or in the circumferential direction of the essentially hollow cylindrical control piston 320; This can prevent and / or minimize a danger or risk of, for example, radial deflection, deviation and / or buckling of the control piston (e.g. with respect to a stroke axis H), especially at high process pressures.

[0079] The clamping element 330, which is essentially sleeve-shaped, can comprise at least one opening 390 (see below). Fig. 3A / B). The at least one opening 390 can be provided like a kind of window or in a window-like manner in an outer wall or on an outer circumference of the essentially sleeve-shaped clamping element 330. It is also possible to provide several openings 390, which, as in Fig. 3A can be identified, for example, with essentially identical dimensions (e.g., length, width, and / or height) and arranged, for example, essentially uniformly distributed in the circumferential direction, e.g., evenly spaced. The at least one opening 390 can, particularly in the assembled state, be dimensioned and / or arranged such that the at least one elongated recess 106, in particular the slot, of the fluid control body 100 is at least partially / sectionarily released (see 3A). Fig. 3A, e.g., at position 360). The at least one opening 390 can be at least partially / sectionarily released both in the closed position or closed state (e.g., second position) and in the open position or open state (e.g., first position). In other words, the clamping element 330, which is essentially sleeve-shaped, can serve only for axial / radial clamping or centering, wherein the at least one elongated recess 106, in particular the slot, of the fluid control body 100 is released or closed by the essentially hollow cylindrical control piston 320.

[0080] As already mentioned, in the Fig. 3A-3D also shows a fixed choke module 340, which includes three exemplary essentially disc-shaped choke elements 350A-C, in particular choke discs (e.g. also Fig. 6A-D, 7A-D and Fig. 8A-D). It should be noted that only a single, essentially disc-shaped throttle element, or two or more, can be used.

[0081] Fig. Figures 3E-F show a schematic and exemplary cross-section / path of a common fluid flow channel 375, which is e.g. through one or more of the essentially disc-shaped throttling elements 350A-C from the Fig. 3A-D, especially throttle discs (e.g. also Fig. 6A-D, 7A-D and Fig. 8A-D) can be trained. Fig. 3E-F is an exemplary fluid flow 375', sketched by the dashed arrow to illustrate which fluid flow is possible through the common fluid flow channel 375. It should be clear that other flows are conceivable or possible. The following sections describe the Fig. 3E-F is described using an example of a fixed throttle module with at least two substantially disc-shaped throttle elements 350A-B, which can be connected or stacked in series, in succession and / or above or below each other, particularly in the flow direction of a process fluid and / or in the direction of the stroke axis, as e.g. in the Fig. 3A-D shown.

[0082] As in the Fig. To identify 3E-F, the at least two essentially disc-shaped throttling elements 350A / B can form at least one common fluid flow channel 375, through which, for example, the fluid can flow along path 375'. The at least one common fluid flow channel 375 can run through both of the at least two essentially disc-shaped throttling elements 350A / B, e.g., path 375'. The common fluid flow channel 375 can connect a first channel 375A of a first 350A, which contains at least two essentially disc-shaped throttling elements 350A / B, with a channel 375B of a second 350B, which contains at least two essentially disc-shaped throttling elements 350A / B, in particular fluidically (e.g., at the point where the fluid flows), such that, for example, the fluid flows through the first 375A and second 375B channels.the common fluid flow channel 375, for example starting from the essentially elongated recess 106, which can pass through and / or penetrate at least two essentially disc-shaped throttling elements 350A / B, e.g., along path 375'. In the example of the . Fig. The fluid can exit through the throttling element 350C, for example. This throttling element 350C can comprise or form one end of the path 375' and / or the common fluid flow channel 375 and / or can have one or more, in particular axially arranged, through-openings in order to distribute the flow, in particular the process fluid flow, e.g. in the outlet or the outlet opening and / or in its direction, into several fluid jets, preferably uniformly.

[0083] The at least two essentially disc-shaped throttle elements 350A / B can each comprise at least one throttle channel; for example, a first essentially disc-shaped throttle element 350A can form a first throttle channel and a second essentially disc-shaped throttle element 350B can form a second throttle channel. These can then be connected, in particular fluidically, for example by alignment, e.g., rotation, and thus form a common fluid flow channel 375.

[0084] The first and / or second throttle channel, as in Fig. 3E-F, shown schematically, can each extend between at least one fluid inlet area and at least one fluid outlet opening, which are subsequently referred to in relation to the Fig. 6A-D, 7A-D and 8A-D will be explained. Fig. Figures 6A-D, 7A-D, and 8A-D show essentially disc-shaped throttle elements 600-800, in particular throttle disks 600-800; according to one or more embodiments, in particular with different geometric configurations, e.g., of one or more throttle channels. For example, the essentially disc-shaped throttle elements 600-800 of Fig. 6A-D, 7A-D and 8A-D each have different throttle channels, which differ from each other in particular in terms of their course, alignment, orientation, shape, (possibly also an inclination), direction, (possibly also a cross-section) and / or size or dimension (for example, length, width, height).

[0085] A fluid inlet area 620-820 can, for example, be a recess 620-820, in particular a groove 620-820, with a depth that is less than the thickness d (see. Fig. 6-8D) of the essentially disc-shaped throttle element 600-800. The at least one fluid outlet opening 610-810, on the other hand, can be designed as a through-opening 610-810, e.g. as a bore or hole, i.e., essentially completely penetrating the throttle element 600-800. The fluid outlet opening 610-810 of a throttle channel of one of the at least two substantially disc-shaped throttle elements 600-800 (for example, a fluid outlet opening 610-810 of the first throttle channel of the first substantially disc-shaped throttle element 600-800) can be connected, coupled and / or aligned with the fluid inlet area 620-820 of a throttle channel of a second of the at least two substantially disc-shaped throttle elements 600-800 (for example, a fluid inlet area 620-820 of the second throttle channel of the second substantially disc-shaped throttle element 600-800), in particular fluidically.As an example, the first and second essentially disc-shaped throttle elements 600-800 can be arranged and / or aligned with each other such that the fluid outlet opening 610-810 of the first throttle channel is located directly above the fluid inlet area 620-820 of the second throttle channel, but not, for example, above the fluid outlet opening 610-810 of the second throttle channel. In this way, the fluid is forced to first penetrate (e.g., essentially completely) the fluid inlet area 620-820 or the second throttle channel before it reaches the fluid outlet opening 610-810 of the second essentially disc-shaped throttle element. At this point, we should also refer again to path 375' from the... Fig. Reference is made to section 3E-F, which includes such an exemplary orientation. As mentioned, this allows one or more fluid flows and / or fluid currents to be advantageously controlled, adjusted, and / or regulated.

[0086] Fig. Figures 4A-5B show a modular throttle mount according to the invention, in which the exemplary throttle modules according to the invention are arranged. Fig. 3A-3D and / or Fig. 6A-8D and / or fluid control bodies 100 / 200 can be used. The explanations mentioned in relation to these figures apply analogously. Fig. Figure 4A shows a throttle receptacle 400 according to the invention, wherein the control piston 320 is in an open position, so that a fluid can enter through the substantially elongated recess 106. Fig. Figure 4B shows a throttle receptacle 400 according to the invention, wherein the control piston 320 is in a closed position, so that the fluid cannot enter through the substantially elongated recess 106.

[0087] It should be noted that the throttle intake according to the invention 400 of the Fig. 4A-5B is set up, configured and / or designed to accommodate or insert different throttle modules, for example adjustable throttle modules such as those found in Fig. 3A-D shown and / or fixed throttle modules, in particular throttle discs such as e.g. in Fig. 3A-F as well as Fig. Figure 6A-8D shows that, for example, i) two or more throttle modules, e.g., essentially, especially structurally, the same or identical, such as two or more fixed throttle modules 350A-C, 600-800 with essentially identical throttle channel profiles or geometries, may be included and / or used in the device. Furthermore, ii) two or more fixed throttle modules 350A-C, 600-800, e.g., with different throttle channel profiles or geometries, may be included and / or used in the device. Furthermore, iii) various combinations of adjustable throttle modules with fixed throttle modules, e.g., as described in point i) and / or ii), are also possible. The number of throttle modules may also be varied; for example, only a single throttle disk may be used.

[0088] The throttle intake 400 according to the invention Fig. 4A-5B can comprise or be formed by a housing body 410. The housing body 410 can comprise an inlet opening 412 or a process fluid inlet and an outlet opening 414 or a process fluid outlet, for example for a process fluid, as well as a passage opening 416 or a process fluid passage arranged between the process fluid inlet and the process fluid outlet (e.g. Fig. 5A). The housing body 410 may also include an actuating opening for inserting an actuating rod 325 and / or a control piston 320 (and / or optionally an actuator). Furthermore, a cover 424, e.g., a housing cover, may be provided, which is attached or attachable to the housing body 410, for example, to close and / or cover the actuating opening. The housing cover may have a through-opening, in particular extending in the direction of a stroke axis H, for the actuating rod 325 and / or the control piston 320 or the like. The actuating rod 325 or the control piston 320 may be translationally movable along the stroke axis H, e.g., in the axial direction of the housing body 410 and / or the actuating rod 325.

[0089] Mounting devices 418, for example flange-like fastening sections, can be provided at both the process fluid inlet and outlet of the housing body for connecting a pipeline for conveying process fluid, in particular a process fluid pipeline, e.g., of the process plant. It is conceivable that the mounting devices 418 can be detachably attached to the process fluid pipeline, e.g., by means of screw connections. In particular, the housing cover can include a fastening section for mounting an actuator 450, in particular a pneumatic actuator, or a yoke, a coupling structure, in particular a lantern or the like, for supporting an actuator 450. The actuator 450 is only indicated, as manual, pneumatic-hydraulic, and / or electric drives can be used.

[0090] The housing body 410 of the throttle receptacle 400 according to the invention can form a receiving chamber 428 (e.g. Fig. 5B), which is set up, configured and / or designed to accommodate or insert the various throttle modules, as already mentioned, for example adjustable throttle modules such as those in Fig. 3A-D shown and / or fixed throttle modules, in particular throttle discs as shown in Fig. 3A-F as well as Fig. 6A-8D shown. The receiving space 428 can in particular be dimensioned such that several throttle modules described herein, in particular in the direction of the stroke axis H or axial direction, can be arranged or stacked one behind the other, one after the other and / or one above the other or one below the other.

[0091] As can be seen, several choke modules 350A-C, 600-800, for example, adjustable choke modules and / or fixed choke modules described herein, can be inserted, placed, arranged, and / or received in the receiving chamber 428, particularly different and / or essentially identical ones. The receiving chamber 428 can, for example, always have the same dimensions; thus, no adaptation, modification, and / or change to it is necessary to accommodate the choke modules, particularly the different and / or essentially identical ones. In this way, choke modules can be easily combined, exchanged, installed, removed, and / or changed, and / or combined or assembled as needed. Furthermore, the receiving chamber 428, in particular its design, dimensions, and / or arrangement, makes it possible to accommodate one or more, for example,The inventive throttle receptacle 400, housing body 410, and / or receiving chamber thus realize a modular design that can be compatible with a plurality of throttle elements described herein. This not only saves resources and time during assembly and maintenance but also enables greater flexibility and multiple applications.

[0092] According to the invention, a size of the receiving space 429, e.g. a dimension, for example a width, length and / or height of the receiving space 429, can be matched to a size, e.g. a dimension, for example a diameter, of the different throttle modules in such a way that the different throttle modules, in a state inserted in the receiving space 429, are in contact on the outside, in particular in the circumferential direction, essentially completely, with a wall of the housing body 410, in particular sealingly.

[0093] As in Fig. As can be seen from Figure 4A, the height h of the receiving space 429 can be dimensioned in the direction of the stroke axis H, i.e., for example, in the axial direction of the housing body 410. The width b of the receiving space can be dimensioned essentially transversely to the stroke axis H and / or be limited by a wall of the housing body 410. The receiving space 429 can be rotationally symmetrical, e.g., essentially cylindrical, for example, having an essentially circular cross-section. In other words, a cavity can be provided for the throttle modules. The receiving space 429 can extend or run essentially straight in the axial direction, i.e., have an essentially constant cross-section. However, other shapes and / or cross-sections are also conceivable.

[0094] What's next in Fig. As can be seen in Figure 4A, the receiving space 429, particularly in the axial direction of the housing body 410 or in the direction of the stroke axis H, can be limited by at least one shoulder, in particular an axial stop. The axial stop can define or determine the width b of the receiving space 429. The at least one shoulder 429 can be formed in or through a wall of the housing body 410, e.g., integrally with it, in one piece, or layer by layer. The at least one shoulder can determine and / or define the height h of the receiving space 429, for example, an insertion height h of the receiving space 429 for the different throttle modules. For example, the position, arrangement, and / or placement of the at least one shoulder in the axial direction or in the direction of the stroke axis H can determine the height h of the receiving space 429 and / or how many throttle modules can be inserted or placed in it, e.g., one above the other, one below the other, or one after the other.At least one of the steps can also serve as a stop, for example to fix, hold, and / or support the throttle modules in the axial direction. In this way, axial support can be provided for the throttle modules.

[0095] The receiving chamber 429 can be located, at least partially and / or section by section, in the area of ​​the passage opening 416, or the process fluid passage (see Fig. 5A) of the housing body 410, for example, essentially between the process fluid inlet and the process fluid outlet. The receiving chamber 429 can, for example, be dimensioned and arranged in the housing body 410 such that the process fluid enters the different throttle modules essentially in an axial direction or in the direction of the stroke axis H of the housing body 410 and / or flows through them sequentially or one after the other. The position and arrangement of the receiving chamber 429 can ensure that a process fluid flows essentially in an axial direction or in the direction of the stroke axis H through the receiving chamber 429 and, if applicable, through throttle modules that can be arranged therein, whereby the process fluid can exert an axial force on them, which can (additionally) fix the throttle modules in the axial direction, e.g., press them against, for example, against the at least one shoulder.

[0096] The throttle modules, when inserted in the receiving chamber 429, can bear against a wall of the housing body 410 on the outside, particularly in the circumferential direction, essentially completely, in a sealing manner, in particular such that the process fluid preferably cannot or does not flow between the wall of the housing body 410 and a circumferential surface of one or more throttle modules, particularly those inserted in the receiving chamber 429. Rather, as mentioned above, the process fluid flows essentially in the axial or vertical direction, or in the direction of the stroke axis H, through the receiving chamber 429, i.e., for example, further inwards in the radial direction, and through the throttle modules that can be arranged therein, for example, through the throttle channels.

[0097] The at least one paragraph can define the insertion height h such that the different throttle modules can be inserted into the receiving space to at least 60%, in particular at least 70%, preferably at least 85%. Alternatively or additionally, the different throttle modules can be inserted into the receiving space to substantially a maximum of 85%, substantially a maximum of 70%, preferably a maximum of 60%. For example, the height h of the receiving space 429 can be such that a large proportion (e.g., the total height) of the throttle modules can be inserted into it, and, when inserted, only an insignificant, e.g., a percentage, protrudes from the receiving space 429 in the direction of the stroke axis H. This ensures, for example, that the throttle modules can be held firmly or securely in the receiving space and / or provides an advantageous fixation. As in Fig. 4A can also be seen as the essentially disc-shaped section 108 being included in the recording space, and, for example, only a part, e.g., the essentially cylindrical section 102, protruding from the recording space 429.

[0098] As in the Fig. As can be seen in Figures 4A-5B, the throttle receptacle 400 according to the invention, in particular the housing body 410, can be designed as an angle valve. For example, the inlet opening 412 and the outlet opening 414 can be arranged essentially at right angles to each other. The receiving chamber 429 can be located essentially below a center line (at 412) of the inlet opening 412, or be arranged and / or formed there. This ensures that the process fluid enters the receiving chamber essentially in the axial direction or in the direction of the stroke axis H.

[0099] In Fig. Figure 5A shows one possibility in which the modular choke receptacle according to the invention comprises exclusively a fixed choke module, for example with one or more choke elements 350A-C and / or 600-800, as e.g. in the Fig. 6A-D, 7A-D and Fig. 8A-D shown. In Fig. Figure 5B shows one possibility in which the modular throttle receptacle according to the invention comprises exclusively the controllable throttle module, e.g. with fluid control body 100 / 200, control piston 320 and clamping sleeve, for which a spacer 431 can be used.
