Description

[0001] The present invention relates to a modular throttle receptacle 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 usable therein, for controlling, in particular for setting and / or regulating, one or more fluid paths and / or fluid flows in the process plant, and a fixed throttle module, in particular usable therein, for controlling, in particular for setting and / or regulating, one or more fluid paths and / or fluid flows in the process plant. Furthermore, the invention relates to a method for providing different fluid paths, in particular fluid characteristic curves, of a fluid flow, in particular process fluid flow, by means of a corresponding modular throttle receptacle and / or a corresponding controllable throttle module and / or a corresponding fixed throttle module.

[0002] Document WO 2021 / 071738 A1 shows a valve for regulating fluid flow, comprising a housing defining a fluid inlet and a fluid outlet. A flow control element is disposed within the housing and 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 includes a plurality of vortex generators that create vortices in the fluid as the fluid flows through the valve seat. A piston is disposed within the housing and is movable relative thereto between a closed and an open position. The piston moves away from the valve seat as the piston moves from the closed position toward the open position, such that fluid flow through the flow control element and the valve seat increases as the piston moves from the closed position to the open position.The piston is designed as a cage valve. The housing, in particular, is structurally designed and constructed specifically for the piston and the flow control element, which adversely affects flexibility and compatibility for various applications. The possible and adjustable fluid paths are also limited.

[0003] Several throttle discs are known from US 10,989,329 B2. Therein, a device for controlling fluid flow is shown, which comprises a body with a central opening extending along a longitudinal axis therethrough, and a plurality of channels extending from an outer side wall of the body to an inner side wall of the body. At least one first channel can intersect at least one other channel, with the throttle discs arranged on a circumference. However, the special structure and the special design make the arrangement incompatible with other valves and complicate the assembly, replacement, and repair of the throttle elements or throttle discs. The fluid paths that can be achieved or adjusted thereby are also limited.

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

[0005] It is an object of the present invention to overcome the disadvantages of the known prior art and in particular to provide an improved throttle receptacle, as well as an improved, in particular usable therein, 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 throttle properties.

[0006] The object is achieved by the features of the independent claims. The dependent claims describe preferred embodiments. Further aspects, advantages, and features emerge from the dependent claims, the description, and the accompanying drawings.

[0007] The invention relates to a modular throttle holder for a process 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 invention aspects and / or embodiments described herein, and fixed throttle modules, in particular according to one or more of the invention aspects and / or embodiments described herein, characterized in that a size of the receiving space is matched to a size of the different throttle modules in such a way that the different throttle modules, when inserted in the receiving space, rest on the outside, in particular in the circumferential direction, essentially completely against a wall of the housing body, in particular in a sealing manner.

[0008] The invention relates to a controllable throttle module, in particular for a modular throttle receptacle according to one or more of the inventive aspects and / or embodiments described herein, for controlling, in particular for adjusting and / or regulating, one or more fluid paths and / or fluid flows 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 portion, which is designed for engagement, in particular in a complementary manner, with a substantially hollow cylindrical control piston; characterized in that the substantially cylindrical portion has at least one elongated recess, in particular a slot, on an outer side, in particular a peripheral surface, wherein the at least one elongated recess, in particular the slot, extends in the axial direction of the fluid control body.

[0010] The invention relates to a fixed throttle module, in particular according to one or more of the invention aspects and / or embodiments described herein and / or in particular for, preferably fluidically, connecting to a controllable throttle module according to one or more of the invention aspects and / or embodiments described herein, for controlling, in particular for adjusting and / or regulating, one or more fluid paths and / or fluid flows 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 throttle elements, which are connected in series, in particular in the flow direction of a process fluid, characterized in that the at least two substantially disc-shaped throttle elements form at least one common fluid flow channel which runs through both of the at least two substantially disc-shaped throttle elements.

[0011] 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 holder according to one or more of the invention aspects and / or embodiments described herein and / or - a controllable throttle module according to one or more of the invention aspects and / or embodiments described herein, and / or - a fixed choke module according to one or more of the invention aspects and / or embodiments described herein.

[0012] A “throttle receptacle” can be understood as a body, a structure, a device and / or a part, e.g. a component, that is designed to accommodate several, in particular different and / or substantially identical, throttle modules, for example controllable throttle modules and / or fixed throttle modules described herein.

[0013] The throttle receptacle according to the invention can comprise a housing body or be formed by it. The housing body can comprise an inlet opening or a process fluid inlet and an outlet opening or a process fluid outlet, for example for a process fluid, as well as a through-opening or a process fluid passage arranged between the process fluid inlet and the process fluid outlet. The housing body can also comprise an actuating 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 or can be fastened to the housing body, for example for closing and / or covering the actuating opening. The housing cover can have a through-opening for the actuating rod and / or the control piston or the like, in particular extending in the direction of a stroke axis.The control piston can be translationally movable along the stroke axis H, e.g., in the axial direction of the housing body and / or the control rod. The control piston can be actuated by means of the control rod or a valve rod.

[0014] When reference is made herein to a substantially "vertical," "axial," or "perpendicular" direction, this may mean a direction that may substantially correspond to the direction of the stroke axis of the control valve and / or the direction of gravity (and vice versa), and when reference is made herein to a substantially "horizontal" or "transverse" direction, this may mean a direction that may substantially correspond to a direction transverse to the direction of the stroke axis and / or the direction of gravity. Explicit reference may be made to corresponding, e.g., other, directions.

[0015] Mounting devices, such as flange-like fastening sections, can be provided at 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-engineering system. It is conceivable to attach the mounting devices to the process fluid pipeline in a detachable manner, e.g., by means of screw connections.

[0016] The throttle holder and / or the housing body can be a one-piece body made of one or more media- and / or temperature-resistant materials. For example, the throttle holder and / or the housing body can be a one-piece cast metal body or forged body, which is partially provided with a machined, for example polished and / or coated, for example painted, powder-coated, chrome-plated, enameled, galvanized or the like, surface. It can be preferred for the housing body to define a housing interior, the openings of which are preferably realized exclusively by the process fluid inlet, the process fluid outlet, and the actuation opening. It is conceivable for the housing body to have further openings to the interior, for example openings for introducing sensors or one or more further process fluid inlets or outlets.

[0017] The housing cover is designed and configured to cover and / or close the actuating opening. In particular, the housing cover can comprise a fastening section for mounting an actuator, in particular a pneumatic actuator, or a yoke, a coupling structure, in particular a lantern, or the like, for supporting an actuator. A corresponding fastening section can also be provided on the housing body. Manual, pneumatic, hydraulic, and / or electric actuators can be used.

[0018] The through-opening may be free of sealants for sealing between the housing cover and the actuating rod. The through-opening may be free of guides, such as a plain bearing, a ball bearing, or the like, for translationally guiding the actuator. The housing cover may be formed from a temperature- and / or media-resistant material. It is conceivable that the same material is selected for the housing body and the housing cover. The housing cover and the housing body may be designed to be in direct contact for mounting the housing cover. For example, the housing body and the housing cover may have corresponding flange sections for fastening the housing cover to the housing body. A coupling structure, in particular a lantern, may also be provided between them, but this is not mandatory.The housing cover may 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.

[0019] Invention aspects and / or embodiments of the throttle receptacle described herein may be suitable, designed, arranged 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.

[0020] The housing body of the throttle receptacle according to the invention can form a receiving space which is arranged, configured and / or designed to receive or insert “different throttle modules”.

[0021] “Different throttle modules” can be understood, for example, to mean that several, in particular different and / or substantially identical, throttle modules can be accommodated. For example, controllable throttle modules and / or fixed throttle modules described herein can be accommodated. As an example, it is possible that i) two or more, e.g. essentially, in particular structurally, the same or identical, throttle modules, e.g. two or more fixed throttle modules with essentially identical throttle channel courses or geometries, are accommodated and / or inserted therein. Furthermore, it is possible that ii) two or more, e.g. in particular structurally, different fixed throttle modules, e.g. with different throttle channel courses or geometries, are accommodated and / or inserted therein. Furthermore, iii) various combinations of controllable throttle modules with fixed throttle modules, e.g. as according to 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 configured to accommodate a plurality of different or substantially identical throttle modules, in particular the throttle modules described herein. The throttle modules described herein and the throttle receptacles described herein can therefore also be understood as a kit, e.g., as a throttle receptacle kit comprising a plurality of different and / or substantially identical throttle modules according to one or more of the inventive aspects and / or exemplary embodiments described herein.

[0022] The receiving space can, in particular, be dimensioned such that several throttle modules described herein can be arranged one behind the other, one after the other, and / or one above the other, in particular in the direction of the stroke axis or axial direction. The throttle modules can be held in the receiving space, for example, by force-fitting and / or form-fitting means.

[0023] A "modular" throttle receptacle can therefore be understood here as meaning that several, in particular different and / or substantially identical, throttle modules, for example, the adjustable throttle modules and / or fixed throttle modules described herein, can be inserted, placed, arranged, or placed, and / or received in the receptacle space. The receptacle space can, for example, always have the same dimensions; therefore, no adaptation, modification, and / or change thereof is necessary to accommodate the, in particular, different and / or substantially identical, throttle modules. In this way, throttle modules can be easily combined, exchanged, installed, removed, and / or changed, and / or combined or assembled, for example, as needed / required. Furthermore, the receptacle space, in particular its design, dimensioning, and / or arrangement, makes it possible to accommodate one or more, for exampleto control, monitor, regulate and / or adjust different fluid paths, fluid jets and / or fluid flows without, for example, having to adapt or change the housing body or without, for example, being forced to always provide different, in particular structurally differently designed, housing bodies. The throttle holder according to the invention or the housing body and / or the receiving space thus realize a modular structure 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 a number of possible uses. A control valve that is equipped, for example, with the modular throttle holder according to the invention can be referred to as a modular control valve.

[0024] According to the invention, a size of the receiving space can be matched to a size of the different throttle modules such that the different throttle modules, when inserted in the receiving space, bear on the outside, in particular in the circumferential direction, essentially completely against a wall of the housing body, in particular in a sealing manner. Alternatively or additionally, the different throttle modules can be arranged or bear against one another, below one another or above one another, in particular in the axial direction. Alternatively or additionally, it is possible to insert the different throttle modules individually in the housing body. For example, the different throttle modules can bear individually in or against the housing body or the wall of the housing body, in particular in the axial direction.

[0025] A “size” can be understood to mean a dimension, for example a width, length and / or height of the receiving space. The height of the receiving space can be dimensioned in the direction of the stroke axis, i.e. e.g. in the axial direction of the housing body. The width of the receiving space can be dimensioned essentially transversely to the stroke axis and / or delimited 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 essentially in a straight line in the axial direction or run in a straight line, i.e. e.g. having an essentially constant cross-section. However, other shapes and / or cross-sections are also conceivable.

[0026] The receiving space can be delimited, in particular in the axial direction of the housing body or in the direction of the stroke axis, by at least one shoulder, in particular an axial stop. The at least one shoulder can be formed in or through a wall of the housing body, e.g. integrally therewith or from one piece or in layers. The at least one shoulder can specify 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, a position, arrangement and / or placement of the at least one shoulder in the axial direction or in the direction of the stroke axis can specify the height of the receiving space and / or how many throttle modules can be inserted or inserted therein, e.g. one above the other, one below the other or one after the other.The at least one shoulder 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 for the throttle modules can be provided.

[0027] The receiving space can be located, at least partially and / or in sections, in the area of ​​the passage opening or the process fluid passage of the housing body, for example, essentially between the process fluid inlet and the process fluid outlet. The receiving space can, for example, be dimensioned and arranged in the housing body such that the process fluid enters the various throttle modules "essentially in the axial direction" or in the direction of the stroke axis of the housing body and / or flows through them sequentially or one after the other. The position and arrangement of the receiving space can ensure that a process fluid flows essentially in the axial direction or in the direction of the stroke axis through the receiving space and any throttle modules that can be arranged therein, whereby the process fluid can exert an axial force on them, which (additionally) fixes the throttle modules in the axial direction, e.g.can press, for example against which it can press at least one shoulder. In this regard, flow in a “substantially axial or vertical direction” should not be understood as absolute, i.e. purely axial or vertical flow, but as effective flow, i.e. the process fluid can, for example, flow within the throttle modules (for example in a throttle channel), at least partially / section-wise also in the radial direction or transversely to the stroke axis (for example, radial partial courses / flows, for example in the plane, are also conceivable), but overall or effectively in the axial direction through the receiving space or the throttle modules.

[0028] When inserted into the receiving space, the throttle modules can rest on the outside, in particular essentially completely in the circumferential direction, against a wall of the housing body, in particular in a substantially sealing manner. By "substantially sealing" can be understood 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, in particular those inserted into the receiving space. Rather, the process fluid flows, as mentioned above, essentially in the axial or vertical direction or in the direction of the stroke axis through the receiving space, e.g. in the radial direction further inward and through the throttle modules that can be arranged therein, for example through the throttle channels.

[0029] The at least one shoulder can determine 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 essentially a maximum of 85%, essentially a maximum of 70%, preferably a maximum of 60%. This can be understood, for example, to mean that a wall or height of the receiving space is such that a large part (e.g. a total height) of the throttle modules can be inserted therein, and, in the inserted state, only an insignificant part, e.g. a percentage, protrudes from the receiving space in the direction of the stroke axis. This ensures, for example, that the throttle modules can be held firmly or securely in the receiving space and / or provides advantageous fixing.The different throttle modules can be connected in series in the receiving space, in particular one above or below each other and / or one after the other in the fluid flow direction, and can be inserted and / or arranged, for example individually. In other words, the different throttle modules can be arranged adjacent to each other and / or stacked on top of each other in the receiving space, for example in such a way that the process fluid can pass through the throttle modules one after the other, in particular in the direction of the stroke axis.

[0030] 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 substantially at right angles to each other. The receiving space can be located substantially below a center line of the inlet opening, or can be arranged and / or formed there. This ensures that the process fluid enters the receiving space substantially in the axial direction.

[0031] According to the invention, a controllable throttle module, in particular for a modular throttle receptacle according to one or more of the inventive aspects and / or embodiments described herein, can be provided for controlling, in particular for adjusting and / or regulating, one or more fluid paths, fluid jets 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.

[0032] A “controllable throttle module” can be understood as a device, structure, facility, part or component, element and / or assembly that is set up and / or designed to influence and / or change a fluid, in particular a process fluid flow, in particular one or more parameters thereof, e.g., a volume flow, flow rate, speed and / or pressure, etc. “Controllable” can, for example, refer to the possibility of, e.g., actively making settings / adjustments, i.e., that the fluid, in particular the process fluid flow, can be controlled, varied, changed and / or regulated, for example, as a result of a 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 paths, fluid jets and / or fluid flows, e.g.,Depending on the position, orientation and / or position of the control rod or control piston.

[0033] According to the invention, a fixed throttle module, in particular for a modular throttle receptacle according to one or more of the inventive aspects and / or exemplary embodiments described herein, and / or in particular for, preferably fluidically, connecting to a controllable throttle module according to one or more of the inventive aspects and / or exemplary embodiments described herein, for controlling, in particular for adjusting and / or regulating, one or more fluid paths, fluid jets 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, can be provided.

[0034] In contrast to an adjustable throttle module, a fixed throttle module can be understood as a device, structure, facility, part or component, element and / or assembly in which no variable or adjustable setting or adjustment of the fluid, in particular the process fluid flow, in particular of one or more parameters thereof, e.g., a volume flow, flow rate, speed and / or pressure, etc., can be made. In other words, fixed throttle modules can have a fixed, unchangeable, predetermined and / or static structure or configuration, e.g., courses and / or geometries of throttle channels, opening diameters, dimensions, etc. Fixed throttle modules cannot therefore be “adjustable.” However, fixed throttle modules can be capable of providing, adjusting, regulating and / or controlling different fluid courses, fluid jets and / or fluid flows, e.g.,compared to a fluid path and / or a 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.

[0035] In the following, we will first look at an example of an adjustable throttle module.

[0036] 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 designed and / or configured for engagement, in particular with a complementary shape, with a substantially hollow-cylindrical control piston. The substantially cylindrical section can preferably be substantially solidly cylindrical. The substantially cylindrical section can have, e.g., on an outer side, in particular a circumferential surface 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 rectilinearly. However, other profiles, e.g., curved, stepped, and / or kinked profiles, are also conceivable.The at least one elongate recess, in particular the slot, can extend in the axial direction of the fluid control body essentially completely over the outer side, in particular the circumferential surface or lateral surface. The at least one elongate 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 elongate recess. For example, the at least one elongate recess, in particular the slot, can have a substantially round cross section. Other cross sections are also possible. It is possible for the cross section to change or vary, for example, in the direction of extension of the at least one elongate recess, in particular the slot, e.g., to taper, for example, in a V-shape. The taper can be continuous, e.g., gradual or steady; or else abrupt, e.g.,initially runs essentially in a straight line and only tapers after a certain distance.

[0037] The fluid control body can comprise a substantially disc-shaped portion 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 disc-shaped portion can be substantially flat and / or planar, for example, also plate-shaped. The substantially disc-shaped portion can be connected to the substantially cylindrical portion, in particular adjoining it; these portions can be manufactured, for example, from a single piece, i.e., in one piece, and / or in layers.The substantially disc-shaped portion may have a larger outer diameter than the substantially cylindrical portion, for example such that the substantially cylindrical portion and the substantially disc-shaped portion form a, in particular circumferential, shoulder, for example a radial shoulder, which runs, for example, in the circumferential direction of the fluid control body.

[0038] The at least one elongated recess, in particular the slot, can extend in the axial direction of the fluid control body through the, in particular substantially disc-shaped, section, preferably substantially completely, and in particular define and / or form therein a fluid passage opening for a process fluid. 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 one-piece body made of one or more media- and / or temperature-resistant materials, for example, a metal.

[0039] A controllable throttle module can comprise a substantially hollow-cylindrical control piston, which can in particular be configured substantially cup-shaped or sleeve-shaped, e.g., substantially hollow-cylindrical, wherein one side or surface can be closed. The substantially hollow-cylindrical control piston can be dimensioned and / or configured to engage with the fluid control body, preferably to receive it, in particular for controlling or regulating the one or more fluid paths and / or fluid flows via the at least one elongated recess, in particular the slot. The dimensions of the substantially hollow-cylindrical control piston, in particular of the cavity, can therefore be matched to the dimensions of the fluid control body, e.g., complementary in shape. 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 apparatus.For example, the substantially hollow-cylindrical control piston can be dimensioned and / or designed to enclose the outer side, in particular the circumferential surface or jacket surface, of the substantially cylindrical section, preferably to enclose, preferably to cover or cover it in such a way that the at least one elongated recess, in particular the slot, and / or the fluid passage opening in the substantially disc-shaped section can be opened and / or closed, in particular at least partially and / or substantially completely, by the control piston, preferably in a controlled manner.

[0040] For example, the control piston can have a first position in which the at least one elongate recess, in particular the slot, and / or the fluid passage opening in the substantially disc-shaped section is substantially open, for example at least partially / section-wise and / or substantially completely. This can be referred to as an open position or open state. The control piston can have a second position in which the at least one elongate recess, in particular the slot, and / or the fluid passage opening in the substantially disc-shaped section is substantially blocked, obstructed and / or closed. This can be referred to as a closed position or closed state. By a movement of the control piston, in particular in the direction of the stroke axis, e.g.Between the first and second positions, different fluid courses, 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.

[0041] The essentially hollow-cylindrical control piston can have a front end surface / closure surface, e.g. a sealing surface or sealing edge, in particular on the front end side (e.g. viewed in the direction of the stroke axis), which, in particular when the controllable throttle module is closed, bears against the essentially disc-shaped section of the fluid control body, in particular in a sealing manner, for example on a substantially planar, level and / or flat surface formed there, for example a seat surface / sealing surface. The essentially disc-shaped section, in particular the seat surface, can form a contour, in particular a shape-complementary or plane-parallel, (e.g. a seat contour and / or a sealing contour or sealing edge) with the sealing surface, in particular on the front end side, which contour can be used for closing (e.g. closed position or closed state). Depending on the fluid and / or degree of sealing orHowever, depending on the sealing class, this contour can also be designed or constructed differently.

[0042] The controllable throttle module can comprise a clamping element, in particular a substantially sleeve-shaped one. A "substantially sleeve-shaped clamping element" is understood to mean a body, element, part or component and / or a structure that is substantially cylindrical, in particular a hollow cylinder. The clamping element, in particular a substantially sleeve-shaped one, can be formed in one piece and / or manufactured in layers, for example from metal, e.g., from the same material as the housing body and / or the fluid control body. The clamping element, in particular a substantially sleeve-shaped one, can be formed, in particular in the assembled state: - to fix the fluid control body, in particular the substantially disc-shaped section, in the axial direction of the fluid control body, in particular to press, compress and / or clamp it; In particular, the substantially sleeve-shaped clamping element can also have, e.g. in the axial direction, a front end surface that can bear against the substantially disc-shaped section, in particular in a sealing manner. This can provide additional axial fixation and / or clamping for the fluid control body and / or possibly further throttle modules; and / or - to receive, surround and / or enclose the substantially 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 substantially 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), particularly at high process pressures.

[0043] The clamping element, which is in particular essentially sleeve-shaped, can comprise at least one opening. The at least one opening can be provided like a type of window or in a window-like manner in an outer wall or on an outer circumference of the essentially sleeve-shaped clamping element. It is also possible to provide a plurality of openings, for example with essentially identical dimensions (e.g. length, width, height), which can be arranged, for example, essentially evenly distributed in the circumferential direction, e.g. evenly spaced. However, different and / or varying distances are also conceivable. A number of openings can be matched to or correspond to a number of the elongated recesses in the fluid control body.The at least one opening can, in particular in the assembled state, be dimensioned and / or arranged such that the at least one elongate recess, in particular the slot, of the fluid control body is at least partially / section-wise exposed. The at least one opening can be at least partially / section-wise exposed both in the closed position or the closed state (e.g. second position) and in the open position or the open state (e.g. first position). In other words, the clamping element, which is in particular essentially sleeve-shaped, can only serve for axial / radial clamping or centering, wherein the at least one elongate recess, in particular the slot, of the fluid control body is exposed or closed / closed by the essentially hollow-cylindrical control piston.

[0044] In a first exemplary embodiment, a fixed throttle module is provided, in particular for a modular throttle receptacle according to one or more of the inventive aspects and / or exemplary embodiments described herein, and / or in particular for, preferably fluidically, connecting to a controllable throttle module according to one or more of the inventive aspects and / or exemplary embodiments described herein, for controlling, in particular for adjusting and / or regulating, one or more fluid paths 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.

[0045] 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 region and at least one fluid outlet opening.

[0046] A "throttle channel" can be referred to as a channel, passage and / or through-passage 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, in particular the process fluid, or to influence the fluid as it passes through the throttle channel, for example to regulate a flow, e.g. to slow it down, throttle it and / or reduce it. In particular, one or more parameters of the fluid, e.g. a volume flow, flow rate, speed and / or pressure, etc., can be influenced or changed by a throttle channel.

[0047] A “fluid inlet area” can be understood as a section, area and / or a point or region at which a fluid can enter, but at which the fluid cannot (e.g. completely) penetrate or exit the throttle element, but is instead passed on, for example, in a radial direction or in a plane. A fluid inlet area can, for example, be a depression, in particular a groove, with a depth that is smaller than the thickness of the essentially disc-shaped throttle element. A “fluid outlet opening”, on the other hand, can be understood as a section, area and / or a point or region at which the fluid can exit or leave the throttle element. The at least one fluid outlet opening can be designed as a through-opening, i.e., for example, can penetrate the throttle element essentially completely.

[0048] According to the invention, the at least one throttle channel can run inclined, in particular obliquely, and / or at an angle with respect to a surface, in particular a cross-sectional area, of the at least one substantially disc-shaped throttle element. In particular, the at least one throttle channel can run inclined, in particular obliquely, and / or at an angle with respect to the, for example, flat, plane and / or level surface or upper side of the substantially disc-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 a 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 region to the at least one fluid outlet opening, for example continuously, steadily and / or gradually.Sudden changes in the form of steps would also be conceivable. This can create a type of self-cleaning effect, e.g. even when the valve is closed, because the fluid, in particular the process fluid, can flow away through the slope, the angle and / or the inclination, whereby impurities can escape through the fluid. The at least one throttle channel can, for example, run at an angle of at least approximately 2°, 3°, 5°, 7°, 10°, 20°, 25°, 30°, 35°, 40°, 45° or even more than 45°, for example 50°, 60°, 75°, with respect to the surface, in particular the cross-sectional area, of the at least one essentially disc-shaped throttle element. An angle or an angular value of the at least one throttle channel can, for example, depend on a thickness of the essentially disc-shaped element; for example, with a greater thickness, a greater angle or a greater inclination can also be selected and / or provided.

[0049] In a second exemplary embodiment, which can be combined with one or more of the invention aspects and / or exemplary embodiments described herein, a fixed throttle module is provided, in particular for a modular throttle receptacle according to one or more of the invention aspects and / or exemplary embodiments described herein, and / or in particular for, preferably fluidically, connecting to a controllable throttle module according to one or more of the invention aspects and / or exemplary embodiments described herein, for controlling, in particular for adjusting and / or regulating, one or more fluid paths 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.

[0050] The fixed throttle module can comprise at least two substantially disc-shaped throttle elements, which can be connected or stacked one behind the other, one after the other, and / or one above the other or one below the other, particularly in the flow direction of a process fluid and / or in the direction of the stroke axis. The at least two substantially 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 substantially disc-shaped throttle elements.A “common fluid flow channel” can be understood as a channel, a passage and / or a through-passage which connects a channel of a first of the at least two substantially disc-shaped throttle elements with a channel of a second of the at least two substantially disc-shaped throttle elements, in particular fluidically, so that, for example, the fluid can pass through and / or penetrate the at least two substantially disc-shaped throttle elements via the first and second, i.e., the common fluid flow channel. The idea behind a common fluid flow channel is that the substantially disc-shaped throttle elements can cooperate or work together to, for example, influence the flow of the fluid. By changes, e.g. of the position, orientation or the like, for example by turning or rotating, and / or by selecting / combining specific ordifferent essentially disc-shaped throttle 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.

[0051] The fixed throttle or the essentially disc-shaped throttle elements can, for example, be inserted, placed, arranged, or placed, and / or received in the receiving space of the throttle holder, e.g. one above the other. The essentially disc-shaped throttle elements can thus be easily combined, exchanged, and / or installed or removed, changed, and / or, e.g., combined or assembled as needed, in order to form, for example, different common 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 one another, e.g., by turning or rotating them, in order to influence or change the common fluid flow channel. In this way, one or more, e.g.,different fluid courses and / or fluid flows can be controlled, monitored, regulated and / or adjusted, whereby the fixed throttle according to the invention realizes a modular structure.

[0052] The at least two substantially disc-shaped throttle elements can be configured substantially identically or can differ, for example, with respect to a geometric configuration, e.g., one or more throttle channels, and / or dimensions (e.g., thickness) and / or a material. For example, the at least two substantially disc-shaped throttle elements can each have different throttle channels, which differ from one another in particular in terms of a course, an alignment, an orientation, a shape, an inclination, a direction, a cross-section, and / or a size or dimension (e.g., a length, width, height).

[0053] The common fluid flow channel can be designed to guide the process fluid sequentially through the at least two essentially disc-shaped throttle elements, wherein in particular the common fluid flow channel guides the process fluid essentially vertically or axially through the at least two throttle elements. As already mentioned, “essentially axially or vertically” should not be understood as an absolute, i.e. purely axial or vertical flow, but rather as an effective flow, i.e. the process fluid can, for example, flow within the at least two essentially disc-shaped throttle elements (for example in a throttle channel), at least partially / section-wise also in the radial direction or transversely to the stroke axis (for example, radialPartial courses / flows, for example in the plane, are conceivable), but overall or effectively in the axial or vertical direction through the at least two essentially disc-shaped throttle elements.

[0054] The at least two substantially disc-shaped throttle elements can each comprise at least one throttle channel. For example, a first substantially disc-shaped throttle element can form a first throttle channel, and a second substantially disc-shaped throttle element can form a second throttle channel. The first and second throttle channels can, as already mentioned, be substantially identical, or differ as mentioned above; reference can be made to the above explanations in this regard. The first and / or second throttle channels can each extend between at least one fluid inlet region 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, in particular fluidically, 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). As an example, the first and second substantially disc-shaped throttle elements can be arranged and / or aligned with one another 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 the fluid inlet region or the second throttle channel (e.g., essentially completely) before reaching the fluid outlet opening of the second, essentially disc-shaped throttle element. As mentioned, this advantageously allows one or more fluid paths and / or fluid flows to be controlled, adjusted, and / or regulated.

[0055] 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 holder according to one or more of the invention aspects and / or embodiments described herein and / or - a controllable throttle module according to one or more of the invention aspects and / or embodiments described herein, and / or - a fixed choke module according to one or more of the invention aspects and / or embodiments described herein.

[0056] The different fluid courses, especially fluid characteristics, can be Varying a geometric configuration, in particular a cross-section and / or a shape, of the at least one elongated recess, in particular the slot, and / or Controlling, in particular adjusting and / or regulating, a stroke of the essentially hollow-cylindrical control piston, be provided.

[0057] The different fluid courses, in particular fluid characteristic curves, can be provided by varying or combining different throttle modules, e.g. with regard to number and design. In particular, these can be provided by varying a geometric design, in particular a course, an alignment, an orientation, a shape, an inclination, a cross-section and / or a size, of the respective throttle channels of the at least two essentially disc-shaped throttle elements. It is also possible to change an alignment / orientation of the at least two essentially disc-shaped throttle elements relative to one another, e.g. by rotating or twisting, in order to influence and / or provide different fluid courses, in particular fluid characteristic curves.

[0058] Furthermore, the method can control, in particular adjust, a damping of the fluid flow by varying a number and / or a configuration, in particular a structure or geometric configuration, for example of the throttle channels, as mentioned above, of the at least two substantially disc-shaped throttle elements.

DESCRIPTION OF PREFERRED EMBODIMENTS

[0060] In the following, the invention will 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.

[0061] The drawings are schematic drawings and are not to scale. Some elements in the drawings may have exaggerated dimensions to emphasize aspects of the present disclosure and / or for presentation clarity. For simplicity, identical reference numerals are used to identify identical elements commonly included in the drawings. It is contemplated that elements and features of one embodiment may be advantageously incorporated into other embodiments without further notice. In general, only the differences with respect to individual embodiments will be described.

[0062] Each embodiment is provided to illustrate the disclosure and is not intended to limit the disclosure. Furthermore, features shown or described as part of one embodiment may be used in conjunction with other embodiments to create another embodiment. The description is intended to encompass such modifications and variations.

[0063] Fig. 1A-D show a fluid control body 100 of a controllable throttle module according to an embodiment. A controllable throttle module is shown, for example, in Fig. 3A-D and 4A-B are shown in more detail. Fig. 1A is a perspective view of the fluid control body 100 and Fig. 1B is 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 sectional view through section AA from Fig. 1C.

[0064] As in the Fig. 1A-D, the fluid control body 100 can comprise a substantially cylindrical portion 102. The substantially cylindrical portion 102 can have, e.g., on an outer side 104, in particular a circumferential surface 104 or lateral surface 104 of the substantially cylindrical portion 102, at least one elongated recess 106, in particular a slot 106, a groove 106 or a notch 106. In the Fig. 1A-D show, in particular, two substantially elongated recesses 106 which are substantially opposite one another, although more or fewer may be provided in the fluid control body 100.

[0065] The at least one elongated recess 106 can extend in the axial direction, or in the direction of the stroke axis H (see e.g. Fig. 4A / B), of the fluid control body 100 and / or run in this direction, for example, essentially straight, as can be seen at the section AA in Fig. 1C. However, other profiles, e.g., curved, stepped, and / or bent profiles, are also conceivable. The at least one elongated recess 106, in particular the slot 106, can extend in the axial direction of the fluid control body 100 substantially completely over the outer side 104, in particular the circumferential surface 104 or the lateral surface 104. As shown in Fig. 1C, the at least one elongate recess 106, in particular the slot 106, has a cross-section that changes or varies, for example, in the direction of extension of the at least one elongate recess 106, i.e., in particular, tapers, for example, in a V-shape. The substantially elongate recess 106 can taper, for example, in the direction of the substantially disk-shaped portion 108. Such a cross-section and / or the arrangement of the recess 106 along the outer surface 104 can 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.

[0066] The fluid control body 100, as shown in the Fig. 1A-D, may comprise a substantially disc-shaped portion 108 which is designed to have a sealing surface or sealing edge (see, for example, seat or sealing surface 380, in particular in Fig. 3A / C) for a substantially hollow cylindrical control piston (see control piston 320 e.g. in Fig. 3A, 3C and 4A-4B), in particular its front end surface (see front end surface / closure surface 370 in particular Fig. 3C). As in Fig. 1A-D, the substantially disc-shaped portion 108 may be substantially flat, planar, and / or level, for example, plate-shaped. The substantially disc-shaped portion 108 may be connected to the substantially cylindrical portion 102. The Fig. 1A-D, i.e. the substantially cylindrical section 102 and the substantially disc-shaped section 108, can be manufactured, for example, from one piece, i.e. in one piece, and / or in layers, e.g. from metal, and / or, for example, by means of a 3D printing process. As shown, for example, in Fig. 1B, the substantially disk-shaped portion 108 may have a larger outer diameter d1 than the substantially cylindrical portion 102 (see diameter d2). The relationship between d1 and d2 may, for example, be such that the substantially cylindrical portion 102 and the substantially disk-shaped portion 108 form a, in particular circumferential, shoulder, for example a radial shoulder, which runs, for example, in the circumferential direction of the fluid control body 100, see, for example, the shoulder 109 in Fig. 1B. The ratio between d1 and d2 can also be chosen so that the Fig. 3A / C recognizable seat or sealing surface 380 (or the shoulder 109) is of sufficient size for the front end surface / closing surface 370 (see Fig. 3C) of the control piston 320.

[0067] As in the average AA of the Fig. 1D, the at least one elongated recess 106, in particular the slot 106, 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 (see e.g. Fig. 1B and Fig. 1D) for a process fluid, whereby advantageous flow and throttling properties can be provided.

[0068] Fig. 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 is a top view of the fluid control body 200. Fig. 2C is a sectional view through section AA of Fig. 2B and Fig. 2D is a side view of the fluid control body 200.

[0069] The basic structure of the fluid control body 200 in the Fig. 2A-D is essentially identical to the fluid control body 100 of Fig. 1A-D, so that reference can be made to the previous explanations in this regard, whereby the Fig. 2A-D, correspondingly adapted reference numerals are used. The fluid control body 200 of the Fig. 2A-D differs, however, in the cross section of the at least one elongated recess 206, in particular the slot 206 and / or the fluid passage opening 210. As in the Fig. 2A-D, the at least one elongated recess 206, in particular the slot 206 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 Fig. 2A-D and / or the arrangement of the recess 106 along the outer surface 104, advantageous flow and throttling properties are also provided, 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.

[0070] Fig. 3A-D shows an assembly 300 comprising a controllable throttle module with a fluid control body, for example a fluid control body 100 as in the Fig. 1A-D (it being clear that alternatively the fluid control body 200 can be arranged as shown in the Fig. 2A-D), as well as a control piston 320, which is attached and / or fixed to an exemplary actuating rod 325, and a clamping sleeve 330, as well as a fixed throttle module 340, which comprises three exemplary substantially disc-shaped throttle elements 350A-C, in particular throttle disks. In other words, the Fig. 3A-D show a combination of an adjustable throttle module and a fixed throttle module comprising several throttle elements, in particular throttle disks. It should be noted that this configuration / arrangement is only exemplary, ie fewer throttle disks 350A-C can be used (e.g., only one) or one or more of the throttle disks 600-800, as shown, for example, in the Fig. 6A-D, 7A-D and Fig. 8A-D shown, used, assembled and / or combined. Furthermore, it is clear that, for example, only one of the two, ie exclusively the adjustable throttle module (cf. e.g. Fig. 5B), e.g. with fluid control body 100 / 200, control piston 320 and clamping sleeve 330, or only the fixed throttle module (cf. e.g. Fig. 5A), e.g. with one or more throttle elements 350A-C and / or 600-800, as in the Fig. 6A-D, 7A-D and Fig. 8A-D can be used.

[0071] As in Fig. 3C, the controllable throttle module can comprise a hollow-cylindrical control piston 320, which can in particular be configured essentially cup-shaped or sleeve-shaped, e.g., essentially hollow-cylindrical, wherein one side or surface can be closed. The essentially hollow-cylindrical control piston 320 can be dimensioned and / or configured to engage with the fluid control body 100, preferably to receive it, in particular for controlling or regulating the one or more fluid paths and / or fluid flows via the at least one elongated recess 106, in particular the slot 106, for example by controlled opening / closing, for example, in particular by translational movement along the stroke axis H.

[0072] As shown in the average of Fig. 3C, the dimensions of the substantially hollow-cylindrical control piston 320, in particular of the cavity 322, can be matched to the dimensions of the fluid control body 100, in particular of the substantially cylindrical section 104, e.g., can be designed / configured to complement the shape. For example, the substantially hollow-cylindrical control piston 320 can be dimensioned and / or configured to enclose the outer side 104, in particular the circumferential surface 104 or jacket surface 104, of the substantially cylindrical section 102, preferably to enclose it in such a way, preferably to cover it orto cover that the at least one elongated recess 106 / 206, in particular the slot 106, and / or the fluid passage opening 110 in the substantially disc-shaped section 108, can be opened and / or closed by the control piston 320, preferably in a controlled manner, 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 e.g. point 360 from . Fig. 3A / 3C where the control piston encloses / surrounds the circumferential surface 104 and the recess 106). By a movement of the control piston 320, in particular 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 (see e.g. closed position in Fig. 4B), in particular including partial positions in between, different fluid courses, 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.

[0073] The substantially hollow-cylindrical control piston 320 can have a front end surface / closure surface 370, e.g. a sealing surface 370, in particular on the front end side (e.g. viewed in the direction of the stroke axis) (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 in a sealing manner, for example against a substantially planar, flat and / or flat surface 380 formed there, for example a seating surface / sealing surface 380 (cf. Fig. 3C). The substantially disc-shaped section 108, in particular the seat surface 380, can form a contour 395, in particular a shape-complementary or plane-parallel contour, with the sealing surface 370, in particular on the front end (e.g. a seat contour and / or a sealing contour 395; as best shown in the Fig. 4B) 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 constructed differently.

[0074] The controllable throttle module may comprise a clamping element 330, in particular one which is essentially sleeve-shaped and which, as shown in Fig. 3A / 3C, is essentially cylindrical, in particular hollow cylindrical, for example with a rotationally symmetrical or essentially circular cavity 322. The clamping element 330, which is in particular essentially sleeve-shaped, can be designed, in particular in the assembled state: - to fix the fluid control body 100, in particular the substantially 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 to press, compress, and / or clamp it; In particular, e.g., in the axial direction, an end face can be provided on the clamping element 330, which can bear against the seat / sealing surface 380 of the substantially disc-shaped section 108 and / or exert a force thereon. This can, for example, provide additional axial fixation and / or clamping for the fluid control body 100 and / or possibly also the further throttle modules 350A-C; and / or - to receive, surround and / or enclose the substantially 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 substantially 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 (for example with respect to a stroke axis H), particularly at high process pressures.

[0075] The clamping element 330, which is in particular substantially sleeve-shaped, can comprise at least one opening 390 (see, for example, Fig. 3A / B). The at least one opening 390 can be provided like a window or window-like in an outer wall or on an outer circumference of the substantially sleeve-shaped clamping element 330. It is also possible to provide several openings 390, which, as in Fig. 3A, for example, with substantially identical dimensions (e.g., length, width, and / or height) and, for example, substantially uniformly distributed in the circumferential direction, e.g., evenly spaced. The at least one opening 390 can, in particular in the assembled state, be dimensioned and / or arranged such that the at least one elongated recess 106, in particular the slot 106, of the fluid control body 100 is at least partially / section-wise exposed (see Fig. 3A, e.g., at point 360). The at least one opening 390 can be at least partially / section-wise exposed both in the closed position or the closed state (e.g., second position) and in the open position or the open state (e.g., first position). In other words, the clamping element 330, which is in particular substantially sleeve-shaped, can serve only for axial / radial clamping or centering, wherein the at least one elongated recess 106, in particular the slot 106, of the fluid control body 100 is exposed or closed by the substantially hollow-cylindrical control piston 320.

[0076] As already mentioned, in the Fig. 3A-3D also shows a fixed throttle module 340 which comprises three exemplary essentially disc-shaped throttle elements 350A-C, in particular throttle disks (see also Fig. 6A-D, 7A-D and Fig. 8A-D). It should be noted that only a single, substantially disc-shaped throttle element or two or more may be used.

[0077] Fig. 3E-F show a schematic and exemplary cross-section / course of a common throttle channel 375, which is formed, for example, by one or more of the substantially disc-shaped throttle elements 350A-C from the Fig. 3A-D, especially throttle discs (see also Fig. 6A-D, 7A-D and Fig. 8A-D). In Fig. 3E-F, an exemplary fluid flow path 375' is outlined by the dashed arrow to illustrate the possible fluid flow path through the common throttle channel 375. It is clear that other paths are also conceivable or possible. Fig. 3E-F 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 one behind the other, one after the other and / or one above the other or one below the other, in particular in the flow direction of a process fluid and / or in the direction of the stroke axis, as shown for example in the Fig. 3A-D.

[0078] As in the Fig. 3E-F, the at least two substantially disc-shaped throttle elements 350A / B can form at least one common fluid flow channel 375, through which, for example, the fluid can flow along the path 375'. The at least one common fluid flow channel 375 can run through both of the at least two substantially disc-shaped throttle elements 350A / B, see e.g. path 375'. The common fluid flow channel 375 can connect a first channel 375A of a first 350A of the at least two substantially disc-shaped throttle elements 350A / B to a channel 375B of a second 350B of the at least two substantially disc-shaped throttle elements 350A / B, in particular fluidically (e.g. at the point 375), so that, for example, the fluid can flow via the first 375A and second 375B channel.the common fluid flow channel 375, for example starting from the substantially elongated recess 106, which can pass through and / or penetrate at least two substantially disc-shaped throttle elements 350A / B, e.g. along path 375'. In the example of the . Fig. 3E-F, the fluid can exit through the throttle element 350C, for example. This throttle element 350C can comprise or form one end of the path 375' and / or the common throttle channel 375 and / or can have one or more, in particular axially arranged, through openings, for example 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.

[0079] The at least two substantially disc-shaped throttle elements 350A / B can each comprise at least one throttle channel 375A / B. For example, a first substantially disc-shaped throttle element 350A can form a first throttle channel 375A, and a second substantially disc-shaped throttle element 350B can form a second throttle channel 375B. These can then be fluidly connected, for example by alignment, e.g., rotation, and thus form a common throttle channel 375.

[0080] The first and / or second throttle channel 375A / B, as shown in Fig. 3E-F, can extend between at least one fluid inlet area and at least one fluid outlet opening, which are subsequently shown with respect to the Fig. 6A-D, 7A-D and 8A-D will be explained. Fig. 6A-D, 7A-D and 8A-D show substantially 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 substantially disc-shaped throttle elements 600-800 of Fig. 6A-D, 7A-D and 8A-D each have different throttle channels, which differ from one another in particular in terms of a course, an alignment, an orientation, a shape (possibly also an inclination), a direction (possibly also a cross-section) and / or a size or dimension (for example a length, width, height).

[0081] A fluid inlet region 620-820 may, for example, be a recess 620-820, in particular a groove 620-820, with a depth that is smaller than the thickness d (see Fig. 6-8D) of the substantially disc-shaped throttle element 600-800. The at least one fluid outlet opening 610-810, however, can be designed as a through-opening 610-810, e.g., as a bore or hole, thus 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, in particular fluidically, with the fluid inlet region 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 region 620-820 of the second throttle channel of the second substantially disc-shaped throttle element 600-800).As an example, the first and second substantially disc-shaped throttle elements 600-800 can be arranged and / or aligned with one another such that the fluid outlet opening 610-810 of the first throttle channel is located directly above the fluid inlet region 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 the fluid inlet region 620-820 or the second throttle channel (e.g., essentially completely) before it reaches the fluid outlet opening 610-810 of the second substantially disc-shaped throttle element. At this point, reference should also be made again to the path 375' from FIGS. Fig. 3E-F, which includes such an exemplary alignment. As mentioned, this advantageously allows one or more fluid paths and / or fluid flows to be controlled, adjusted, and / or regulated.

[0082] Fig. 4A-5B show a modular throttle receptacle according to the invention, in which the exemplary throttle modules according to the invention according to the Fig. 3A-3D and / or Fig. 6A-8D and / or fluid control body 100 / 200. In this respect, the statements made with regard to these figures apply analogously. Fig. 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. In Fig. 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.

[0083] It should be noted that the throttle holder 400 according to the invention of the Fig. 4A-5B is arranged, configured and / or designed to receive or insert different throttle modules, for example adjustable throttle modules such as in Fig. 3A-D and / or fixed throttle modules, especially throttle discs such as in Fig. 3A-F and Fig. 6A-8D. As an example, it is possible that i) two or more, e.g. essentially, in particular structurally, the same or identical, throttle modules, e.g. two or more fixed throttle modules 350A-C, 600-800 with essentially identical throttle channel courses or geometries, are accommodated and / or inserted therein. Furthermore, it is possible that ii) two or more, e.g. in particular structurally, different fixed throttle modules 350A-C, 600-800, e.g. with different throttle channel courses or geometries, are accommodated and / or inserted therein. Furthermore, iii) various combinations of controllable throttle modules with fixed throttle modules, e.g. as according to point i) and / or ii), are also possible. Furthermore, the number of throttle modules can be varied, e.g. only a single throttle disk can be used.

[0084] The throttle holder 400 according to the invention of the Fig. 4A-5B may comprise or be formed by a housing body 410. The housing body 410 may comprise an inlet opening 412 or a process fluid inlet 412 and an outlet opening 414 or a process fluid outlet 414, for example for a process fluid, as well as a passage opening 416 or a process fluid passage 416 arranged between the process fluid inlet 412 and the process fluid outlet 414 (see, for example, Fig. 5A). The housing body 410 can also comprise 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 424, can be provided, which is or can be fastened to the housing body 410, for example, to close and / or cover the actuating opening. The housing cover 424 can 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 can be movable in translation along the stroke axis H, e.g., in the axial direction of the housing body 410 and / or the actuating rod 325.

[0085] Mounting devices 418, for example flange-like fastening sections 418, for connecting a respective pipeline for conveying process fluid, in particular a process fluid pipeline, e.g. of the process-engineering system, can be provided at the process fluid inlet 412 and at the process fluid outlet 414 of the housing body 414. It is conceivable to fasten the mounting devices 418, for example, detachably to the process fluid pipeline, e.g., by means of screw connections. In particular, the housing cover 424 can comprise a fastening section for mounting a, in particular, pneumatic actuator 450 or a yoke, a coupling structure, in particular a lantern or the like, for supporting an actuator 450. The actuator 450 is merely indicated, since manual, pneumatic, hydraulic and / or electric drives can be used.

[0086] The housing body 410 of the throttle receptacle 400 according to the invention can form a receiving space 428 (see e.g. Fig. 5B), which is set up, configured and / or designed to receive or insert the different throttle modules, as already mentioned, for example adjustable throttle modules such as in Fig. 3A-D and / or fixed throttle modules, in particular throttle discs as shown in Fig. 3A-F and Fig. 6A-8D. The receiving space 428 can, in particular, be dimensioned such that a plurality of throttle modules described herein can be arranged or stacked one behind the other, one after the other, and / or one above the other or one below the other, in particular in the direction of the stroke axis H or axial direction.

[0087] As can be seen, several, in particular different and / or substantially identical, throttle modules 350A-C, 600-800, for example, controllable throttle modules and / or fixed throttle modules described herein, can be inserted, inserted, arranged or placed therein, and / or received in the receiving space 428. The receiving space 428 can, for example, always have the same dimensions; therefore, no adaptation, modification and / or change thereof is necessary to accommodate the, in particular, different and / or substantially identical, throttle modules. In this way, throttle modules can be easily combined, exchanged, installed or removed and / or changed, and / or also, e.g., combined or assembled as needed / required. Furthermore, the receiving space 428, in particular its design, dimensioning and / or arrangement, makes it possible to accommodate one or more, e.g.to control, monitor, regulate, and / or adjust various fluid paths and / or fluid flows without, for example, having to adapt or modify the housing body 410, or without, for example, being forced to always provide different, in particular structurally differently designed, housing bodies 410 for this purpose. The throttle receptacle 400 according to the invention or the housing body 410 and / or the receptacle space 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 possible uses.

[0088] 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, when inserted in the receiving space 429, rest on the outside, in particular in the circumferential direction essentially completely, against a wall of the housing body 410, in particular in a sealing manner.

[0089] As in Fig. 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 substantially transversely to the stroke axis H and / or be delimited by a wall of the housing body 410. The receiving space 429 can be rotationally symmetrical, e.g., substantially cylindrical, for example, having a substantially circular cross-section. In other words, a cavity can be provided for the throttle modules. The receiving space 429 can extend substantially rectilinearly in the axial direction or run rectilinearly, i.e., for example, have a substantially constant cross-section. However, other shapes and / or cross-sections are also conceivable.

[0090] How to continue in Fig. 4A, the receiving space 429 can be delimited, in particular in the axial direction of the housing body 410 or in the direction of the stroke axis H, by at least one shoulder 429, in particular an axial stop 429. The axial stop 429 can define or fix 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 therewith or from one piece or in layers. The at least one shoulder 429 can fix 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, a 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 arranged therein, e.g., one above the other or one below the other orone after the other. The at least one shoulder 429 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 for the throttle modules can be provided.

[0091] The receiving space 429 can be located, at least partially and / or in sections, in the region of the passage opening 416 or the process fluid passage 416 (cf. Fig. 5A) of the housing body 410, for example, essentially between the process fluid inlet 412 and the process fluid outlet 414. The receiving space 429 can, for example, be dimensioned and arranged in the housing body 410 such that the process fluid enters the various throttle modules essentially in the 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 space 429 can ensure that a process fluid flows essentially in the axial direction or in the direction of the stroke axis H through the receiving space 429 and any throttle modules that can be arranged therein, whereby the process fluid can exert an axial force on them, which (additionally) fixes the throttle modules in the axial direction, e.g., can press them, for example, can press them against the at least one shoulder 429.

[0092] When inserted into the receiving space 429, the throttle modules can rest on the outside, in particular essentially completely in the circumferential direction, against a wall of the housing body 410, in particular in a substantially sealing manner, in particular in such a way 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, in particular those inserted into the receiving space 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 space 429, i.e., for example, in the radial direction further inward and through the throttle modules that can be arranged therein, for example through the throttle channels.

[0093] The at least one shoulder 429 can determine 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 essentially a maximum of 85%, essentially a maximum of 70%, preferably a maximum of 60%. For example, a height h of the receiving space 429 can be such that a large part (e.g., a total height) of the throttle modules can be inserted therein, and, in the inserted state, only an insignificant, e.g., 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 advantageous fixation. As in Fig. 4A, the substantially disc-shaped section 108 can also be accommodated in the receiving space, and for example only a part, for example the substantially cylindrical section 102, can protrude from the receiving space 429.

[0094] As in the Fig. 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 substantially at right angles to one another. The receiving space 429 can be located substantially below a center line (at 412) of the inlet opening 412, or can be arranged and / or formed there. This ensures that the process fluid enters the receiving space substantially in the axial direction or in the direction of the stroke axis H.

[0095] In Fig. 5A shows a possibility in which the modular throttle holder according to the invention comprises exclusively a fixed throttle module, for example with one or more throttle elements 350A-C and / or 600-800, as shown in the Fig. 6A-D, 7A-D and Fig. 8A-D. In Fig. 5B shows a possibility in which the modular throttle holder according to the invention exclusively comprises the controllable throttle module, e.g. with fluid control body 100 / 200, control piston 320 and clamping sleeve 330, wherein a spacer 431 can be used for this purpose.
