Regulating device for regulating a fluid flow, in particular a stopcock, fluid line system and method for regulating a fluid flow

The invention relates to a regulating device for regulating a fluid flow, in particular a stopcock, a fluid line system comprising a regulating device, and a method for regulating a fluid flow.

Regulating devices are used in particular for regulating a fluid flow through a fluid line system, for example a hose arrangement, wherein preferably a fluid flow rate and / or a fluid flow volume is regulated. In this case, it is generally necessary that the regulating device is designed to be fluid-tight despite the regulating properties, so that substantially no fluid, in particular unintentionally, can escape from the fluid line system in the area or in the vicinity of the regulating device and the fluid flow thus essentially within the Fluid line system is located. Moreover, it is often a requirement that the regulator be controllable. The control of a regulating device can preferably take place either manually by an operator or semi-automatically until automatically, for example by means of an electrical and / or electronic control.

Simple regulators may include, for example, binary control logic having a closed position and a flow position. In the In the closed position, the regulating device has substantially no flow from an inlet to an outlet. In turn, in the flow-through position, the regulating device has a flow from an inlet to an outlet. In addition, regulators may have more than these two regulatory states. For example, a regulating device between the closed position and the flow-through position may have further positions in which the flow rate and / or the flow volume can be set specifically. Furthermore, a continuous adjustment of the flow rate and / or the flow volume can be made possible. In addition to the tightness and the ability to control the regulator, it is often also a requirement of regulators that they be applicable to specific applications. For example, with regard to physical properties, the fluid to be conveyed makes demands on the design of the regulating device or on the material of the regulating device. The existing regulators and methods of operating such regulators offer several advantages, but further improvements are desirable.

It is therefore an object of the present invention to provide a solution which reduces or eliminates one or more disadvantages of existing regulator devices.

The regulating device comprises at least the housing and the adjusting device. The main body of the adjusting device is preferably arranged coaxially within the adjustment chamber of the housing. The arrangement of the adjusting device and in particular of the base body of the adjusting device within the adjusting chamber and the arrangement of the passage opening within the base body of the adjusting device allows adjustment of the adjusting device in a passage position and in a closed position. In the passage position, the passage opening is arranged relative to the inlet opening and the outlet opening such that they preferably have a common passage axis.

Alternatively, preferably, the passage opening, the inlet opening and the outlet opening on a common passage, said common passage does not necessarily have to lie on a passage axis. For example, the aforementioned passage may include curves and / or other changes in direction. In particular, the adjusting device can be arranged in a closed position within the adjusting chamber, in which the seal having radial outer peripheral surface of the base body of the adjusting device is arranged at the inlet opening and / or the outlet opening, that the inlet opening and / or the outlet opening is arranged completely on this radial outer peripheral surface is or are and are thus covered in the closed position of the radial outer peripheral surface. In the closed position, substantially no fluid can pass from the inlet opening through the through-opening to the outlet opening. The inlet opening and the outlet opening may be arranged on the adjustment chamber such that they have coaxially aligned passage directions.

FIG. 1 shows a three-dimensional view of an exemplary embodiment of a housing of a regulating device. The housing 10 extends from an inlet connection end 104 to an outlet connection end 144. Adjacent to the inlet connection end 104, the inlet region 100 of the housing 10 is arranged. At the end of the inlet region 100, which faces away from the inlet connection end 104, the adjustment chamber 120 is arranged. The entrance region 100 has a substantially tubular geometry formed by a wall 102 becomes. The first opening of the tubular geometry of the inlet region 100 is arranged at the inlet connection end 104. A second opening of the inlet region 100 opposite this first opening is arranged on the adjustment chamber 120, in particular this opening of the inlet region 100 is arranged on an inlet opening (not shown) of the adjustment chamber 120. In particular, the arrangement of the inlet region 100 on the adjustment chamber 120 is such that fluid could flow from the inlet region 100 into the adjustment chamber 120, and the connection between the inlet 102 and inlet 122 wall 122 is fluid-tight, particularly vacuum-tight , It is particularly preferred that the inlet opening (not shown) on the adjustment chamber 120 has the same orifice with respect to shape and / or size as the internal diameter of the inlet area 100.

The adjustment chamber 120 also has a tubular geometry formed by the radial wall 122, forming an inner peripheral surface 124. The entrance port, not shown, is located on the radial wall 122 of the adjustment chamber 120. As a result, the entrance area 100 is disposed on a radially outer circumferential surface of the adjustment chamber 120. A center axis M of the adjustment chamber 120 is thus aligned orthogonal to a center axis of the entrance region 100. At the opposite side of the inlet opening of the adjustment chamber 120, an outlet opening, not shown, is arranged, wherein the outlet area 140 is arranged at this outlet opening. The exit region 140 has, analogously to the entry region, a tubular geometry that is formed by the radial conversion 142. The exit region 140 borders with the end facing away from the adjustment chamber 120 and forms the outlet connection end 144. The arrangement of the outlet region on the adjustment chamber 120 is analogous to the arrangement of the inlet region 100 formed on the adjustment chamber 120. In particular, in this embodiment of the housing 10, the center axes of the inlet region 100 and the outlet region 140 are arranged coaxially with each other. Further preferably, the central axes of the inlet region 100 and / or the outlet region 140 are arranged coaxially to the inlet opening and / or outlet opening.

The inlet region 100 has a seal 108 at a region which adjoins the inlet connection end 104. In addition, the inlet region 100 in a region between the seal 108 and the adjustment chamber 120 has a stationary Part of a bayonet lock 106 on. The exit region 140 also has a seal 148 in a region adjacent the exit port end 144. The exit region 140 further includes a stationary portion of a bayonet catch 146 between the seal 148 and the adjustment chamber 120. FIG. 2 shows a three-dimensional view of an exemplary embodiment of an adjusting device of a regulating device. FIG. 2 shows, in particular, an adjusting device 20 having a base body 200 and a passage opening 204 passing through the base body 200. The passage opening 204 extends from a first passage end 206 to a second passage end (not shown). The through-hole 204 is arranged such that a center axis of the through-hole 204 is orthogonal to a center axis of the cylindrically shaped main body 200. In particular, the passage opening 204 is arranged such that the center axis of the passage opening 204 and the center axis of the base body 200 have an intersection. The passage opening 204 has a diameter orthogonal to the passage direction, which is smaller than the diameter of the base body 200.

A seal 202 is arranged on the outer circumferential surface of the main body 200, wherein the seal 202 has a planar recess in the region of the openings into the passage opening 204, preferably in the size of the cross section orthogonal to the passage direction of the passage opening 204. In addition, the adjusting device 20 at a front end locking elements 212. At the opposite end of the adjusting device 20, a rotary handle 210 is arranged, which also has securing elements 208. These securing elements 208 are designed and arranged to correspond to a flange 126 of the housing shown in FIG. This is done in particular after the adjustment device 20 is arranged with its base body 200 within the adjustment chamber 120, as shown in Figure 4 and is explained in the description of this figure.

FIG. 3 shows a three-dimensional view of an exemplary embodiment of an inlet coupling element for a regulating device. The entry coupling member 30 extends from a hose connection end 300 to an entry end portion 302 and has between these two ends 300, 302 a hose connection portion 304 adjacent the hose connection end 300, an intermediate portion 306 disposed thereon, and a closure portion 308 disposed on the intermediate portion 306 adjacent to the entrance end 302, on. To the Hose connection portion 304, three radial shoulders 312 are arranged, which are formed as annular geometries and are arranged coaxially on the outer peripheral surface of the hose connecting portion. The outer diameter of these annularly shaped radial shoulders is slightly larger than the outer diameter of the hose connection region 304.

The outer diameter of the intermediate region 306 is greater than the outer diameter of the hose connection region 304 and also greater than the outer diameter of the radial shoulder 312. The diameter of the closure region 308, in particular the inner diameter of the closure region 308, is formed such that an inlet region or an outlet region of a housing of a regulating device can be arranged within this closure region 308. The entry coupling element 30 furthermore has the counterparts to the stationary parts of the bayonet closure 106, 146 of the housing 10 shown in FIG. In particular, the inlet coupling element 30 has a first bayonet closure opening 314 and a second bayonet closure opening 316 for this purpose. In addition, the entry coupling element has a bayonet catch projection 318.

FIG. 4 shows a three-dimensional, partially transparent view of an exemplary embodiment of a regulating device. The regulating device 1 has the housing 10, the adjusting device 20 as well as an inlet coupling element 30 and an outlet coupling element 40. In this transparent representation of the regulating device 1, in particular the inlet opening 128 and the outlet opening 130 are shown, which extend through the radial conversion of the adjusting chamber 120 and have coaxially arranged passage directions. In the present case, the regulating device is in a passage position in which the adjusting device 20 or the base body 200 with its passage opening 204 is arranged such that the inlets of the passage opening are arranged at the inlet opening 128 and the outlet opening 130. Thus, a fluid entering the regulator 1 at the first connection end 2 can flow through the inlet coupling element 30, the inlet region 100, the inlet opening 128, the through-opening 204, the outlet opening 130, the outlet region 140 and through the outlet coupling element 40 and at the second connection end 4 exit from the regulating device 1.

Now, when the adjusting device 20 is rotated about the central axis of the base body 200, the flow area for a flowing fluid is reduced by the entrances of the passage opening 204 only partially adjoin the inlet opening 128 and the outlet opening 130. If the adjusting device 20 is rotated for example by 90 ° about the central axis of the base body, it can be seen that the inlets of the passage opening 204 are not arranged at the inlet opening 128 and the outlet opening 130. In this case, substantially no fluid can pass from the first terminal end 2 to the second terminal end 4 through the regulating device 1.

Axially to the center axis of the adjustment chamber 120, the adjustment device is disposed substantially non-movably within the adjustment chamber 120. This is achieved inter alia by securing elements 208, which are fixedly arranged on the rotary handle, which is fixedly connected to the base body. The securing elements 208 form with the flange 126 on the housing 10 a snap connection. By the snap connection, the adjusting device 20 is fixed on the one hand in the axial direction, on the other hand in the radial direction to the central axis M of the adjustment chamber 120 movable and thus rotatably arranged.

FIG. 5 shows a three-dimensional partial view of a regulating device according to FIG. 4. In particular, FIG. 5 shows the regulating device 1 with an inlet coupling element 30 in an assembled state, before the inlet coupling element 30 is fastened to the housing 10 by means of the bayonet closure. FIG. 6 shows a further three-dimensional partial view of a regulating device according to FIG. 4. FIG. 6 shows in particular how the inlet coupling element 30 is arranged on the housing 10, but has not yet been secured. FIG. 7 shows a further three-dimensional partial view of a regulating device according to FIG. 4. In particular, FIG. 7 shows the entry coupling element 30 in a secured position, wherein the entry coupling element 30 is preferably locked in this position, so that detachment is possible only with a predetermined force. In particular, it is preferred that this connection, by the aforementioned seals 108, 148 on the housing 10, is formed fluid-tight or vacuum-tight.

By regulating device 1 according to the invention, a particularly advantageous and cost-effective regulation of a fluid flow can be realized. Due to the simple structure of the regulating device 1 with a housing 10, which can be made in particular of plastic, and an adjusting device 20, which may also be made of plastic, a particularly efficient regulation of a fluid flow is possible. In addition, the arrangement differs trained coupling elements at the inlet region 100 or at the outlet region 140, the possibility of different fluid conveying elements, such as hoses and / or pipes to connect to the regulating device 1.
