Definitions
- the invention relates to a valve with a valve housing and at least one first and second valve opening as well as a channel extending in the valve housing between the first and second valve opening, a throttle module being arranged in a throttle section of the channel so that it can be moved in such a way that it has the cross section of the channel Throttle section limited.
- valves are usually used in systems for the transport of fluids, such as liquids, vapors or gases, in order to be able to regulate or control the transport in a targeted manner. At the same time, the valve can also be completely shut off, thereby interrupting the transport of the respective fluid.
- valves are designed, on the one hand, on the basis of safety-relevant aspects and, on the other hand, on the basis of fluidic considerations.
- the flow should only be influenced as little as possible in a fully open operating state.
- the influence is generally indicated in the form of a drag coefficient or a pressure loss coefficient.
- This coefficient is a measure of the pressure loss in a component through which flow occurs and is usually represented by the dimensionless number zeta, which relates the pressure difference between the inlet and outlet of the valve to the dynamic pressure.
- the drag coefficient is not the only criterion on the basis of which a valve is designed.
- the valve is primarily used for regulating purposes, it is necessary that a certain pressure difference between the inlet and outlet of the valve is brought about in a not fully opened state. This pressure difference is achieved in that the throttle module limits the cross section of the channel depending on the position. The limitation leads to a reduction in pressure.
- characteristic curves that map the flow via the position of the throttle module.
- the characteristic curves used as standard are linear characteristics in which the same relative changes in path lead to the same changes in the relative flow rate.
- equal-percentage characteristics are known in which the same relative changes in path lead to an identical percentage change in the relative flow rate.
- Characteristic curves are standard. Both are equal.
- valves with the defined characteristics are used to regulate or control flow-guiding systems.
- a valve can only take on a regulating function in a system if the authority is high. This means that the valve largely determines the pressure loss in a flow-carrying system. Accordingly, the greater the pressure loss that can be achieved through the valve, the greater the authority.
- the problem here is that valves that have great authority, on the other hand, still have very large drag coefficients in a fully open operating state. On the other hand, for example, a flap, a slide valve or a tap do not have a large one Authorities open, ie it is difficult to regulate with them, but on the other hand they only lead to a slight loss of pressure when fully open.
- the selected resistance coefficient and thus the resulting authority required over the design of the valve.
- the chosen drag coefficient defines the authority.
- the present invention is based on the object of specifying a valve that allows universal use in flow-guiding systems.
- the channel has no bend at least in the throttle section and the throttle module is arranged to be movable parallel to the throttle section.
- the throttle module can be moved parallel to the throttle section. In this way, a continuous and uniform delimitation of the cross-section of the duct can be achieved.
- the channel cross-section is limited by a method perpendicular to the channel. If the channel has a round cross-section, for example, regardless of the design of the throttle module, each throttle position leads to a change in the cross-sectional shape.
- the present invention now makes it possible for a change in the cross-sectional area of the channel to be brought about without influencing the cross-sectional shape of the channel. With a channel with a circular cross-section and a circular throttle module an annular flow channel forms between the throttle module and the channel, the width of which is either reduced or increased by moving the throttle module parallel to the throttle module.
- the channel preferably has no bend in the entire area starting from the inlet opening and extending up to the outlet opening along the longitudinal direction. This means that a flow does not experience a deflection caused by the housing or that the area centers of a cross-sectional area of the channel are arranged at the same level along the longitudinal direction.
- the channel has no flow dividers caused by the housing for targeted flow deflection.
- the channel is formed without an angled shape, according to an advantageous embodiment it nevertheless widens starting from the second valve opening along the longitudinal direction until just before the first valve opening, the channel then tapering up to the first valve opening.
- the channel has no bend from the inlet opening to the outlet opening. This means that the medium exits the valve in the same direction as it entered the valve through the throttle area.
- the throttle module is preferably guided between the inlet opening and the outlet opening. It proves to be advantageous if the throttle module is guided exclusively between two points. In a preferred variant of the invention, these two points are formed by an element in the area of the inlet opening and an element in the area of the outlet opening.
- the element in the area of the inlet opening is preferably a valve seat part.
- a guide element that can flow through is preferably used.
- the throttle module is moved in parallel. It proves to be advantageous if there is at least one guidance through the valve seat.
- the area centers of the cross-sectional areas of the channel are preferably arranged at the same height along a longitudinal direction from the inlet opening to the outlet opening.
- the valve is preferably suitable for enabling the flow to be completely shut off.
- the throttle module has a throttle head which, in a completely closed state of the valve, bears in a sealing manner on a valve seat, the valve seat being arranged in the throttle section.
- the cross-section of the channel through which the flow can flow is determined by the shape of the throttle head and the valve seat, since the smallest flow-through cross-section of the channel is formed between the throttle head and the valve seat regardless of the valve position.
- the valve seat particularly preferably directly adjoins the first valve opening. Since the first valve opening can be designed as an inlet opening for the flow in an operational state. However, the invention also includes embodiments in which the first valve opening is designed as an outlet opening. Due to the immediate arrangement of the valve seat on the first valve opening, it is particularly possible, please include to form the valve seat on a separate valve seat part which is detachably arranged in the first valve opening.
- the geometry of the valve seat can be adapted to the respective throttle head. It is also possible to vary the shape of the throttle head. In this way there are numerous variants for realizing a desired valve characteristic.
- the valve can be used for a large number of purposes by providing a modular system with a large number of throttle heads and valve seats.
- the valve seat part can be fastened to the valve housing via fastening means, for example by a screw or clamp connection.
- a drive rod is mounted on the throttle head, via which an external force can be transmitted to the throttle head.
- the drive rod like the throttle head, is arranged in the throttle section of the channel.
- the power is transmitted via a combination of toothed rack and toothed wheel, the drive rod being designed in sections as a toothed rod into which the toothed wheel engages.
- the gear is like the drive rod to arranged in the channel and rotatably attached to a channel wall of the Ventilge housing. By rotating the gear, the drive rod with the throttle head and thus the throttle module can be moved.
- the gear and the rack section of the drive rod are designed so that the throttle module can be moved from a fully open to a fully closed state by rotating the gear by 30 ° to 60 °, preferably 45 °.
- a swivel wheel is rotatably mounted in the channel on the channel wall of the valve housing, and connected to the drive gear via a push rod.
- the push rod is fastened to the swivel wheel at a distance from the axis of rotation, the fastening on the swivel wheel as well as on the push rod enabling rotation.
- the rotation of the swivel wheel can be translated into a linear movement of the drive rod.
- the swivel wheel and the drive rod are designed so that the throttle module can be moved from a fully open to a fully closed state by rotating the swivel wheel by 0 to 100 °, preferably by 90 °.
- both in an embodiment with a toothed wheel and in an embodiment with a swivel wheel these are preferably actuated by means of a drive, in particular an electric motor.
- a drive in particular an electric motor.
- a pneumatic or electro-pneumatic drive is also possible.
- manual operation is also possible, please include.
- the gear or the swivel wheel can be operated via a lever.
- the shape of the throttle head largely determines the characteristic curve of the valve. For this reason, some forms of the throttle head have been shown to be particularly suitable.
- the throttle head is preferably designed as a parabolic cone, a perforated cone or in the form of a V-port cone.
- the throttle module is mounted so as to be linearly movable via a guide element, the guide element having an opening into which the drive rod engages.
- This guide element enables the drive rod and thus also the entire throttle module to be moved linearly and is particularly useful when a rotational movement has to be translated into a linear movement either via a gearwheel or a swivel wheel.
- a lever construction can also be used.
- the movement is preferably realized by eccentric lever kinematics. This is done by the eccentric arrangement of an element. This allows a rotational movement to be converted into a linear movement.
- the guide element is preferably formed separately and arranged in the channel, preferably in the second valve opening. In a variant, the guide element is directly adjacent to the outlet opening. It has proven to be particularly advantageous if tool-free assembly or disassembly is possible.
- the valve seat part is arranged in the first valve opening and the guide element is arranged in the second valve opening.
- the guide element is designed in such a way that a flow through the guide element is made possible. If this were not the case, the drive rod and the guide element would block the second valve opening.
- One way of ensuring a through-flow is, for example, to provide an opening in the guide element.
- the guide element can be designed in such a way that not only a flow is enabled, but that the cross-sectional area of the guide element that can effectively flow through is determined by the position of the drive rod in the guide element.
- the characteristic curve of the valve can be set not only as a function of the geometry of the throttle head and the valve seat, but also to a decisive extent via the guide element.
- the guide element has a plurality of channel-like openings, the cross-sectional area which can effectively be flowed through preferably being adjustable in that the drive rod blocks and / or keeps a number of the channel-like openings free.
- An inlet flow into these channel-like openings ideally takes place in the axial direction or parallel to the drive rod.
- the outlet flow is preferably partially or completely perpendicular to the drive rod, so that the channels are open towards the drive rod. Depending on the position of the drive rod, a certain number of channel-like openings is blocked or kept free.
- the guide element can also have only one or more channel-like openings, whereby the cross-sectional area which can effectively be traversed is thereby it is adjustable that the drive rod at least partially blocks the channel-like opening or the kanalar term openings.
- the degree of blocking does not depend on the number of blocked channel-like openings, but rather on the degree of blocking of the individual channel-like openings.
- valve housing is preferably made in one piece. However, multi-part designs, e.g. two-part designs, are also possible.
- the valve housing is preferably formed as a cast part or as a welded part.
- the throttle module and / or the guide element are preferably manufactured using additive positioning methods.
- the assembly of the modular internal parts is preferably done without tools as a plug-in system.
- a particularly advantageous embodiment of the invention provides for the integration of a measuring device for measuring operating data; the volume flow is preferably measured.
- the measurement is made using various sensors, preferably two ultrasonic sensors.
- FIG. 1 shows a plan view of a valve according to the invention
- FIG. 2 shows a cross section of the valve according to FIG. 1 along the sectional axis A-
- FIG. 3 shows a cross section of the valve according to FIG. 1 along the sectional axis B-
- the valve has a valve housing 1 which can be installed at both ends via a flange 9 each in a flow-guiding system.
- the flanges 9 each have bores for receiving fasteners. These are preferably screw connections.
- a channel 4 is provided which opens at the ends of the Ventilgeophu ses 1 in a first and a second valve opening 2,3.
- the valve is operated in such a way that the first valve opening 2 is set up as an inlet opening and the second valve opening 3 is set up as an outlet opening for the flow. Accordingly, an operating medium flows against the illustrated longitudinal direction L.
- the channel 4 has no bends along the longitudinal direction L. This means that a flow does not experience a deflection caused by the housing or that the surface centers of a cross-sectional surface of the channel 4 are arranged along the longitudinal direction L at a height. The consequence of this configuration is that when the valve is in a fully open state, only a very small pressure loss develops between the valve openings 2, 3. Although the channel 4 is designed without an angled shape, it nevertheless widens starting from the second valve opening 3 along the longitudinal direction until just before the first valve opening 2, with the channel 4 then tapering up to the first valve opening 2.
- a throttle module 6 consisting of a throttle head 7 and a drive rod 8 is arranged in a throttle section 5 of the channel 4 and can be moved parallel to the throttle section 4 along the longitudinal direction L.
- the throttle portion 5 is formed without an angle, the valve being provided, as already explained above, along the entire channel 4 has no angle from.
- the throttle head 7 is designed in the form of a parabolic cone and, when the valve is completely closed, seals off with a valve seat.
- This The valve seat is formed on a separate valve seat part 10, the valve seat part 10 being arranged in the first valve opening 2. Between the throttle head 7 and the valve seat part 10, the narrowest flow-through area of the valve is always formed, so that the required pressure loss across the valve can be adjusted depending on the position of the throttle module 6 through the specific design of these components.
- the throttle head 7 is arranged at one end of the drive rod 8 and a section of the drive rod 8 is designed as a rack section 11.
- This rack section 11 has several teeth arranged one behind the other.
- the rack section 11 cooperates with a gear 12 which is rotatably arranged in the channel 4 and can be operated from the outside via a gear shaft 13. Because the gear 12 is in engagement with the rack section 11, a rotation of the gear shaft 13 leads to a linear movement of the throttle module 6 along or against the longitudinal direction L. The direction of the movement depends on the direction of rotation of the gear shaft 13.
- the gear shaft 13 To operate the gear shaft 13 it is connected to a drive, not shown, preferably an electric motor, the throttle module 6 being moved from a fully closed to a fully open position by rotating the gear shaft 13 by preferably 90 °.
- a drive not shown, preferably an electric motor
- the drive rod 8 is arranged completely within the channel 4 and is guided linearly along or against the longitudinal direction L via a guide element 14.
- the drive rod is preferably guided over exactly two points. It proves to be particularly advantageous if the second point is formed by the valve seat 10 and the throttle head 7, so that the drive rod 8 is guided downstream of the guide element and upstream through the valve seat 10 in which the throttle head 7 is located moved, wherein the throttle head 7 has elements which ensure guidance on the walls of the valve seat 10. These elements are preferably designed as webs. Movement outside the longitudinal direction L is also blocked by the guide element 14. To ensure leadership is in the Guide element 14 is provided with an opening into which the drive rod 8 engages. The guide element 14 is arranged in the second valve opening 3.
- the guide element 14 does not block the channel 4 at the second valve opening 3
- a large number of channel-like openings 15 are provided in the guide element 14, which allow a through-flow.
- the channel-like openings 15 run in such a way that, depending on the position of the drive rod 8, a certain number of channel-like openings 15 are blocked or released. In this way, the characteristic curve of the valve in combination with the throttle head 7 and the valve seat part 10 can be set in a targeted manner via the guide element 14.
- the guide element 14 contributes to the pressure loss.
- the channel-like openings 15 not only run along the longitudinal direction L but also branch off in the vertical direction H. Thus, part of the flow can flow vertically inwards into the channel 4, provided that the vertical sections of the channel-like openings 15 are free ben.
- the guide element 14, the throttle head 7 and the valve seat part 10 are also designed to be detachable and preferably modular.
- these components can be selected and installed in the valve.
