FLOW REGULATOR AND REGULATOR THEREFOR

Description

[0001] The invention relates to a flow rate regulating device for a heating or cooling system comprising a housing, comprising an inlet nozzle with an inlet opening for a heating or cooling medium as the working medium, comprising a quantity regulating module provided in the housing, which can change a flow for the working medium depending on a presetting and a pressure difference, and comprising a handle which cooperates with a regulating insert of the quantity regulating module, which is arranged movably in a module housing of the quantity regulating module, in order to change the presetting, wherein the quantity regulating module has a regulating pot which is held longitudinally displaceably in relation to the regulating insert and supported against the regulating insert via a regulating spring of the quantity regulating module, with a regulating pot facing the inlet opening,closed pot base and a pot rim projecting from the pot base, as well as a first flow opening of variable size and a second flow opening pre-adjustable via the handle. Furthermore, the invention relates to a regulating device for this purpose.

[0002] A generic flow rate regulating device is known from EP 2 988 071 A1. This device includes a flow rate regulating module with a regulating insert and a regulating cup, which is spring-loaded and longitudinally displaceable relative to a sleeve of the flow rate regulating module and varies the size of a first flow opening depending on the position. The size of a second flow opening can be adjusted by rotating the regulating insert relative to the sleeve, in that the regulating insert more or less covers an opening for the working medium formed on the sleeve's casing side, depending on the rotational position.

[0003] Further flow rate regulating devices are known from DE 10 2009 033 376 B4, DE 10 2009 061 242 B3 and EP 2 985 667 A1.

[0004] The object of the present invention is to provide a flow rate regulating device which is improved with regard to the flow conditions and a regulating device therefor.

[0005] To achieve the object, the invention in conjunction with the preamble of patent claim 1 is characterized in that the first flow opening is formed as a first flow gap, wherein the first flow gap is arranged upstream of the second flow gap with respect to a flow direction of the working medium and wherein the first flow gap is formed between the pot rim and an inner jacket surface of a functional component of the quantity regulating module facing the pot rim, wherein the inner jacket surface encompasses the pot rim on the outside or jacket side in any case in individual regulating positions of the quantity regulating module.

[0006] The particular advantage of the invention is that by implementing the flow openings as variable flow gaps, the flow resistance for the working medium can be reduced. This results in favorable dynamic control behavior and an extremely low tendency to oscillate when the pressure of the incoming working medium changes. Such pressure fluctuations can occur during operation of a fluid pump in a heating or cooling system.

[0007] The provision of the first flow gap between the pot rim and the inner surface facing it promotes a compact design. Consequently, the flow rate regulation device according to the invention can be easily installed in existing heating or cooling systems. It is therefore no larger than devices described in the prior art.

[0008] According to a preferred embodiment of the invention, the flow rate regulation device provides a secondary actuation module. The secondary actuation module comprises a valve pin that is longitudinally displaceable relative to a module housing of the secondary actuation module against a compression spring, a plate held at an end of the valve pin facing the flow rate regulation module, and a seal secured to the plate. The size of the outlet gap for the working medium is determined depending on a longitudinal position of the valve pin. The outlet gap is formed between the seal of the secondary actuation module and an actuation ring of the flow rate regulation module, wherein the actuation ring is operatively connected to the handle and serves to adjust the size of the second flow gap.

[0009] The valve pin can, for example, be connected to a temperature sensor that is not part of the secondary actuation module. In this case, the secondary actuation module is designed as a temperature control module, with the longitudinal position of the valve pin relative to the module housing being determined by a temperature measurement from the temperature sensor. The handle can be designed as part of the temperature control module. For example, a return temperature limiter can be provided as a secondary actuation module. For example, the secondary actuation module can interact with an electromotive actuation unit and serve for the time-controlled adjustment of the size of the outlet gap.

[0010] The flow control device can therefore comprise two essential functional modules: the flow control module and the secondary actuation module. The modular design promotes economical production and simple assembly. Furthermore, the modular design reduces maintenance and installation effort, and in particular, simplifies the replacement of defective functional components.

[0011] The flow control module with two flow gaps is used to set a target flow value, for example, for a room temperature, and to adjust the flow rate of the working medium to the required flow rate. The target flow is preset by adjusting the size of the second flow gap via the handle. In particular, a rotary actuation of the handle is provided here. The size of the first flow gap is influenced by the pressure difference of the working medium in the inlet connection, on the one hand, and after flowing through the second flow gap, on the other.

[0012] The secondary actuation module also influences the flow rate of the working medium through the size of the outlet gap. If the secondary actuation module is designed as a temperature control module, the current room temperature is determined as the temperature measurement value of the temperature sensor. Depending on the actual room temperature, the longitudinal position of the valve pin then influences the size of the outlet gap.

[0013] According to a further development of the invention, the first flow gap and / or the second flow gap are arranged coaxially to one another and / or to a longitudinal center axis of the flow rate regulating device and / or the flow rate regulating module. The coaxial arrangement of the flow gaps, which represent throttling points for the working medium, advantageously further reduces the flow resistance when flowing through the flow rate regulating module.

[0014] According to a further development of the invention, the inner surface facing the pot rim tapers in the flow direction of the working medium, whereas an outer surface of the regulating pot, formed by the pot rim and facing the inner surface, is preferably cylindrical. The inner surface preferably tapers conically in the flow direction. Advantageously, the shape of the inner surface and the outer surface facing it allows the size of the flow gap to be adjusted very precisely and sensitively depending on the longitudinal adjustment position of the regulating pot.

[0015] According to a further development of the invention, the first flow gap and / or the second flow gap are formed annularly as a first annular gap and / or as a second annular gap. The first and / or the second annular gap can have a constant or non-constant width determined perpendicular to a circumferential direction.

[0016] According to a further development of the invention, the first flow gap and / or the second flow gap are segmented and preferably designed in the shape of a ring segment. The width of the first flow gap and / or the second flow gap, determined in the circumferential direction, can be constant or vary.

[0017] In a further development of the invention, the inner circumferential surface is profiled. Preferably, protrusions are provided on this surface to profile the inner circumferential surface. The protrusions can be arranged at regular intervals in the circumferential direction and / or serve to segment the first flow gap.

[0018] According to a further development of the invention, the formations are wedge-shaped and / or have a triangular cross-section. Preferably, the first flow gap formed between the inner circumferential surface and the regulating pot is segmented by the formations and has a non-constant width.

[0019] According to a further development of the invention, the regulating insert provides a through-bore which connects a fluid chamber arranged downstream of the second flow gap with respect to the flow direction of the working medium with an interior space of the regulating pot. In particular, the through-bore is elongated in the flow direction of the working medium. The provision of the through-bore advantageously makes it possible to allow the pressure of the incoming working medium to act against the spring force of the regulating spring, on the one hand, and the pressure of the working medium after flowing through the second flow gap, on the other hand. This results in automatic adjustment of the size of the first flow gap depending on the pressure of the incoming working medium, with the result that pressure fluctuations in a supply line are compensated.

[0020] According to a further development of the invention, the module housing of the flow control module is constructed in several parts. It provides an outer module housing sleeve and a housing insert, which is at least partially encompassed by the module housing sleeve on the shell side.

[0021] For example, the housing insert, as a functional component of the flow control module, provides the inner surface. Advantageously, the multi-part module housing can be manufactured easily and cost-effectively. While the module housing sleeve serves as the shaping component of the flow control module and is easy to manufacture due to its simple geometry, the housing insert, with its precisely machined inner surface, can be manufactured separately. For example, the housing insert can be manufactured by machining, primary forming, or an additive manufacturing process.

[0022] According to a further development of the invention, the regulating insert is conically shaped in sections. The second flow gap is formed between the conical shape of the regulating insert and the module housing of the flow control module. Preferably, the second flow gap is formed between the conical shape and the housing insert of the module housing. The housing insert thus defines the first and second flow gaps.

[0023] According to a further development of the invention, the regulating insert comprises a plurality of threaded ring segments held by webs, wherein the threaded ring segments have an external thread that engages with a correspondingly shaped internal thread of the flow control module. Preferably, the housing insert of the module housing provides the internal thread of the flow control module. Engagement recesses are provided between adjacent webs or adjacent threaded ring segments of the regulating insert. Actuating fingers projecting from the actuating ring of the flow control module engage in these engagement recesses to transmit an actuating movement of the handle to the regulating insert.

[0024] According to a development of the invention, the inlet nozzle and / or the inlet opening and / or the first flow gap and / or the second flow gap and / or the outlet gap and / or the regulating insert and / or the through-bore and / or the regulating pot and / or the pot rim and / or the regulating spring and / or the actuating ring and / or the module housing sleeve and / or the housing insert and / or the valve pin and / or the compression spring and / or the plate and / or the seal and / or the handle are arranged coaxially to one another and / or to the longitudinal central axis.

[0025] To achieve this object, the invention has the features of patent claim 15. Accordingly, a regulating device for the flow rate regulating device according to the invention comprises the flow rate regulating module and the secondary actuation module, which is designed in particular as a temperature control module and provides the handle. Advantageously, existing heating or cooling systems, in particular, can be easily converted or modernized by removing an existing regulating device from a housing of an existing flow rate regulating device and installing the regulating device according to the invention into the existing housing. The connection dimensions of the regulating device according to the invention can be adapted to the dimensions of existing regulating devices.

[0026] The flow rate regulating device according to the invention and the regulating insert according to the invention can be used, for example, in a floor heating or cooling system.

[0027] Further advantages, features, and details of the invention can be derived from the further subclaims and the following description. Features mentioned therein may be essential to the invention individually or in any combination. Features and details of the flow rate regulating device described according to the invention naturally also apply in connection with the regulating device, and vice versa. Thus, the disclosure of the individual aspects of the invention can always be referenced reciprocally. The drawings serve merely as examples to clarify the invention. They are not limiting in nature.

[0028] They show: Fig. 1 shows a longitudinal section through a first embodiment of a flow rate regulating device according to the invention with a housing, with a temperature control module as a secondary actuation module and with a quantity regulating module in a first regulating position, Fig. 2 shows a perspective sectional view of a regulating device providing the temperature control module and the quantity regulating module of the flow rate regulating device according to the invention according to Fig. 1 in the first regulating position, Fig. 3 a longitudinal section through the regulating device of the flow rate regulating device according to the invention according to Fig. 2 in a second regulating position, Fig. 4 a perspective view of the regulating device according to the Fig. 2 and 3, Fig. 5 a section AA through the quantity regulating module of a regulating device according to the invention in a second embodiment and Fig. 6 a longitudinal section through the quantity regulating module of the regulating device according to Fig. 5 .

[0029] A flow rate regulation device or a regulation device for this purpose are included in the Fig. 1 to 4The flow rate regulating device comprises a housing 1 with a presetting nozzle 9, an inlet nozzle 2 secured to the housing 1 with an inlet opening 3, and the regulating device according to the invention with a quantity regulating module 20 and a secondary actuation module, which in the present case is exemplified as a temperature control module 10. The inlet nozzle 2 is sealed against the housing 1 by a seal 5. A module housing 11 of the temperature control module 10 is sealed against the housing 1 of the flow rate regulating device by a seal 6. A further seal 7 is provided between the inlet nozzle 2 and the quantity regulating module 20 of the regulating device.

[0030] The temperature control module 10 comprises a module housing 11. It provides a valve pin 12 arranged longitudinally displaceable relative to the module housing 11 against a compression spring 13, a plate 14 held at an end of the valve pin 12 facing the flow control module 20, and a seal 15 held on the plate 14. The spring 12 is arranged in a sleeve 18 through which the valve pin 12 extends at its end.

[0031] The sleeve 18 is encompassed by the handle 16. The handle 16 is rotatable about a longitudinal central axis 8 in the module housing 11 of the temperature control module 10. The valve pin 12 and the handle 16 engage through the presetting nozzle 9 into the housing 1 of the flow rate regulator.

[0032] The pin 12 and the sleeve 18 with the compression spring 13 are held on the handle 16 by a guide ring 19. A cap 17 surrounds the handle 16 at an end of the temperature control module 10 facing away from the plate 14 and the seal 15. The cap 17 provides a recess on its front side through which the valve pin 12 is guided outward.

[0033] The valve pin 12 can be connected to a commercially available temperature sensor (not shown in the figures) that can be attached to the regulating device or flow rate regulator. The temperature sensor can be used to influence the longitudinal position of the valve pin 12. The valve pin 12 is moved against the compression spring 13, which, as a cylindrical spring, is clamped against the sleeve 18 on the one hand and against the valve pin 12 via a snap ring on the other.

[0034] The flow control module 20 coupled to the temperature control module 10 provides a multi-part module housing with an outer module housing sleeve 21 and an annular or hollow-cylindrical housing insert 22, which is encompassed by the module housing sleeve 21 on the outer side. Furthermore, a control insert 24 is provided, which is encompassed by the module housing sleeve 21 and partially protrudes into the housing insert 22.

[0035] The regulating insert 24 provides a pot guide 26 at an end facing away from the temperature control module 10, via which a regulating pot 30 of the flow control module 20 is supported on the regulating insert 24 in a longitudinally displaceable manner. The regulating pot 30 provides a pot base 32 facing the inlet opening 3 and a pot rim 31 projecting from it in the direction of the regulating insert 24. A regulating spring 33 is provided in the regulating pot 30, via which the regulating pot 30 is supported against the regulating insert 24.

[0036] The regulating insert 24 provides a plurality of threaded ring segments 27 distributed in a circumferential direction, which are held by webs 28. Engagement recesses 29 are formed between adjacent webs 28 or adjacent threaded ring segments 27 of the regulating insert 24. The threaded ring segments 27 provide an external thread that engages a correspondingly shaped internal thread of the flow control module 20. In the present embodiment of the invention, the internal thread is provided on the housing insert 22 of the module housing.

[0037] The module housing sleeve 21, the housing insert 22, the regulating insert 23, the regulating pot 30 and the regulating spring 33 of the quantity regulating module 20 and the valve pin 12, the compression spring 13, the plate 14, the seal 15, the handle 16, the sleeve 18 and the guide ring 19 of the temperature control module 10 are arranged coaxially to the longitudinal central axis 8.

[0038] The flow control module 20 further provides an actuating ring 34, which is also arranged coaxially to the longitudinal center axis 8 and faces the seal 15 of the temperature control module 10. Actuating fingers 35 protrude from the actuating ring 34 in the direction of the regulating insert 24. The actuating fingers 35 engage in the engagement recesses 29 formed on the regulating insert 24. The actuating ring 34 is operatively connected to the handle 16. A rotational movement of the handle 16 is thus transmitted to the regulating insert 24 via the actuating ring 34 and the actuating fingers 35. Due to the thread, the rotation of the handle 16 is converted into a longitudinal displacement of the regulating insert 24 in the direction of the longitudinal center axis 8.

[0039] At one end facing the inlet opening 3, a plurality of outwardly projecting stops 36 are formed on the regulating pot 30. The stops 36 are designed in such a way that they can be Fig. 1 In the illustrated first regulating position of the flow control module 20, in which the regulating pot 30 is in a first end position, they rest against a step 37 formed on the inside of the module housing sleeve 21. The housing insert 22 is provided opposite the step 37 formed on the module housing sleeve 21. The housing insert 22, together with the module housing sleeve 21, forms a further step against which the regulating pot 30 rests with the stops 36 in a second end position thereof.

[0040] The assignment of the quantity control module 20 to the temperature control module 10 is such that an outlet gap 42 for a working medium is formed between the seal 15 of the temperature control module 10 and the actuating ring 34 of the quantity control module 20, which serves as a valve seat. This outlet gap 42 flows into the flow control device via the inlet opening 3 and then flows through the quantity control module 20. In the quantity control module 20, a first annular flow gap 40 serving as the first flow opening and a second annular flow gap 41 serving as a second flow opening for the working medium and as annular gaps 40, 41 are formed. The second flow gap 41 is arranged downstream of the first flow gap 40 with respect to a flow direction 4 of the working medium.

[0041] The first flow gap 40 is provided coaxially with the longitudinal central axis 8 and coaxially with the second flow gap 41. It is formed between a cylindrical outer surface of the regulating pot 30 in the region of the pot rim 31, on the one hand, and an inner surface 23, which faces the pot rim 31 with the outer surface and is formed on the housing insert 22, and extends essentially radially. The inner surface 23 tapers conically in the flow direction 4 of the working medium, with the result that a displacement of the regulating pot 30 in the direction of the longitudinal central axis 8 varies the size or opening dimension of the first flow gap 40.

[0042] The second flow gap 41 is formed between the regulating insert 24 and the housing insert 22 and extends essentially axially. For this purpose, the regulating insert 24 is conically shaped in sections. The size of the second flow gap 41 formed between the conical shape of the regulating insert 24 and the housing insert 22 of the module housing can be adjusted or changed by the longitudinal position of the regulating insert 24 and thus by the rotational position of the handle 16. In this respect, it is possible to define a basic flow through the flow control module 20 via the rotational position of the handle 16. The basic flow corresponds to a target room temperature of the heating or cooling system.

[0043] In order to compensate for pressure fluctuations in the working medium in an inlet line connected to the inlet nozzle 2, the size of the first flow gap 40 is adjusted depending on the pressure. To this end, the regulating insert 24 has a through-bore 25 which leads from a fluid chamber formed behind the second flow gap 41 into the interior of the regulating pot 30. If the working medium now reaches the inlet nozzle 2 at a pressure p 1, a pressure drop occurs as it flows through the first flow gap 40, with the result that a pressure p 2 for the working medium is established behind the first flow gap 40. The pressure is reduced again as it flows through the second flow gap 41, with the result that the working medium in the fluid chamber and thus also inside the regulating pot 30 has a further reduced pressure p 3.As a result of the pressure difference between the pressures p 1 , p 3 prevailing on opposite sides of the pot bottom 32 and taking into account a spring constant of the regulating spring 33, the relative position of the regulating pot 30 to the regulating insert 24 is now automatically adjusted depending on the pressure or flow rate.

[0044] The size of the outlet gap 42 ultimately depends on the distance between the seal 15 of the temperature control module 10 and the actuating ring 34 serving as the valve seat. Here, the valve pin 12 is displaced in the direction of the longitudinal center axis 8 depending on a temperature measurement value from the temperature sensor (not shown). Depending on a difference between a predetermined target room temperature and an actual room temperature, the size of the outlet gap 42 and thus the amount of working medium flowing through the flow rate control device varies.

[0045] In the present exemplary embodiment, the secondary actuation module is designed merely as an example, as a temperature control module 10. For example, the secondary actuation module can interact with an electromotive actuation unit for the time-controlled adjustment of the size of the outlet gap 42, or a return temperature limiter can be provided as the secondary actuation module. For example, the flow rate regulation device according to the invention can be designed without the secondary actuation module.

[0046] The Figures 5 and 6show a second embodiment of the flow rate regulating device according to the invention with a modified flow rate regulating module 20. The flow rate regulating module 20 provides wedge-shaped formations 38 on the inner circumferential surface 23 of the housing insert 22 facing the regulating insert 24. The regularly formed wedge formations 38, which are arranged at equal distances in the circumferential direction of the inner circumferential surface 23, taper in a wedge shape in the flow direction 4. The first flow gap 40, which is formed between the inner circumferential surface 23 with the wedge formations 38 on the one hand and the outer circumferential surface of the regulating pot 30 on the other hand, is segmented by the wedge formations 38 or has a non-constant width determined perpendicular to the circumferential direction.

[0047] To the extent that in the second exemplary embodiment of the flow rate regulation device the wedge formations 38 are regularly shaped and / or the wedge formations 38 are evenly distributed or evenly spaced in the circumferential direction of the inner circumferential surface 23, this is merely an exemplary embodiment. The formations can be irregularly shaped and / or unevenly distributed. The wedge shape of the formations is also exemplary.
