Definitions

  • the invention concerns a regulator of flow of fluids with multiple regulation valves, mainly for regulation of a flow of air in the ventilation elements, systems and distributions.
  • the regulation valves regulate the flow together with the setting mechanism; the regulator keeps the set flow of the liquid in the broad adjustable scope and with high precision.
  • the invention allows for modular construction suitable for large flow cross-sections, too.
  • the electronic control systems can be used, where the assessment of the pressure gathers the actual flow and subsequently control the rotation of the regulation valve (publication EP1980798A2 , SK UV 8137). More often, the mechanically regulated regulation valves are used, which are simple, cheap and do not require a source of energy.
  • the flat blade of the valve of the mechanical regulator is shaped in such a way that the first side of the valve creates different force moment as the other side of the valve.
  • the resulting difference in moments during the flow of fluid is in balance with the strength of the spring which has adjustable prestress (publications DE10222673C1 , DE20214414U1 , FR1313310A , SK U3174 ).
  • the prestress sets the desired flow.
  • a damper is part of the mechanism, which prevents the vibration of the valve with the spring.
  • the invention is defined in claims 1 to 15.
  • the deficiencies in the state of art are significantly remedied by the adjusting regulator of the flow of the fluids, mainly flow of the air in the ventilation elements at larger flow cross-sections, where the regulator has a channel for the flow of the fluid, whereby the regulation is achieved by means of the valve tiltably placed in the body of the channel; the valve is connected with the adjusting mechanism placed outside the inside of the channel; and where the adjusting mechanism includes a spring and a damper which act upon the valve according to this invention which essence lies in the fact that the regulator has in the channel's body tiltably placed at least two regulation valves; each valve has its own adjusting mechanism placed outside the inside of the channel; each adjusting mechanism includes a lever of the valve, a spring, a damper and an adjusting element for the adjustement of the prestress of the spring, where the spring connected with the adjusting element acts upon the valve's lever, and where the damper is connected with the valve's lever, whereby the adjusting elements of all adjusting mechanisms of the valve
  • An important feature of the proposed invention with multiple valves is the indirect regulation coupling of the regulation valves, the angular position of the valves is not directly connected, but each valve has its own adjusting mechanism and only the controls of the adjusting mechanisms are connected. The change in deviation of one valve is not transferred to the deviation of the other valve, but such deviation is regulated within the respective adjusting mechanism.
  • the adjusting elements will usually be coupled in such a way that they alive have identical value of the adjustment, that is, identical value of the prestress of the spring for the valve.
  • Such arrangement will in preferable arrangement involve identical regulation valves and identical adjusting mechanisms of each valve. The channel in such adjustment will be separated to parts with similar cross-sections and similar valves.
  • the advantage of the proposed invention is the easy construction of the regulator with the larger flow cross-section, mainly with rectangular cross-section, into which two or more regulation valves are placed, preferably with the parallel axes of rotation in the plane which is perpendicular to the direction of the flow of the fluid.
  • An own adjusting mechanism is attached ot each valve. If the valves are similar, which will be the most common arrangement, each valve will have similar adjusting mechanism with similar spring and similar damper.
  • valves in a single regulator separates the respective flow cross-section to multiple zones with independently regulated valves, thanks to which the valves react independently to the irregularly running and dissimilar states within the flow cross-section.
  • the flows are regulated independently for the zones of individual valves, which achieves the stable summary flow of the whole regulator.
  • the adjusting element has a lock of the position which sets the desired flow of the fluid, or it has a motorized position control which can remotely alter the desired flow.
  • the adjusting element forms a support for one end of the spring; the other end of the spring is connected with the valve's lever. After the manual or motorized setting of the position the adjusting element fors a firm support for the spring.
  • a lock of the adjusting element or the self-lock of the motorized control element in the non-active position serves this point.
  • the individual adjusting elements lack their own lock but it is preferrable if that element which achieves the common coupling of the adjusting elements has a lock.
  • a solution is also possible where the own lock is left with a single adjusting element and other adjusting elements lack the lock, or are carried or blocked by the adjusting element which has the lock.
  • the coupling can be created by a draw rod which connects the rotation of all adjusting elements.
  • it can be a coupling by means of a chain drive, wires, gear wheels, toothed belt, and so on.
  • the position of a draw rod can be simply lockped by the screw connection which rauns through the longitudional groove.
  • the screw connection connects the draw rod with the firm support which is connected, for example, with the body of the channel or with the basic plate of a single adjusting mechanism.
  • the lock of the desired position of the draw rod or a single adjusting element can be solved by means of a screw which forms a friction joint of the draw rod, or by adjusting element with a base plate or a casing which is connected with the base plate.
  • the casing can also create a support for the rotational or tiltable placement of some element or multiple elements of the setting mechanism.
  • the outer surface of the casing can have connecting elements or at least connecting guiding for mounting of the motorized action mamber by which one can change the position of the adjusting element pursuant to the instructions from the superior system.
  • the regulation of the constant flow itself is in the regulator ensured by the mechanical arrangement according to this invention, but the change of the desired flow can be controlled remotely.
  • the partition is placed between the neighboring valves. With two valves a single partition is used; with three valves two partitions are used.
  • the partition forms in the body of the channel two independent regulation zones for each regulation valve.
  • the partition's dimension in the direction of flow is identical as or larger than the height of the valve, that is, the dimension of the valve led perpendicularly to the axis of its rotation.
  • a flat board place just behind the axis of the valve in the direction of the fluid's flow has positive effect on the increase the repeated accuracy of the resultion flow.
  • the board prevents the turbulences behind the regulation valve's blade.
  • the board is oriented in the direction of the flow in the channel of the regulator and has a length which is at least half the height of the regulation valve, preferably the leght corresponds to the height of the regulation valve.
  • the board can have a lock for the maximally open valve. In case the board is produced from the sheet metal, the lock can be produced as an overpress (embossment) with the sufficient height.
  • the lock of the opposite position for the maximally closed valve can be on the inner sheath of the body of the channel, for example simply in form of the protruding shank of the blind rivet.
  • the board behind the valve separates the flows of the fluid which arise behind the valve from its dissimilarly sloped sides of the blade; it prevents the mixing of these flows just behind the valve. It is preferable if the board is placed in such a way that its front edge is placed just behind the axis of the rotation of the valve with the gap necessary for the smooth rotation of the valve, whereby the board is parallel with the direction of flow and it separates the place behind the valve to the identically large spaces.
  • the rear edge of the board can have straight or rounded course in the groundplan.
  • the board will be produced from the sheet metal, the rounded edges will be riveted to the inner surface of the channel's sheath.
  • the board can have a fold formed in the vicinity of the valve's placement.
  • the strenghtening fold can be part of the height shoulder of the board, which simplifies the approachement of the front edge of the board to the shaft of the valve during the placement of the board in the middle of the regulator's pipeline.
  • the valve together with the lever is balanced or at least statically balanced against the axis of the rotation. Since the blade of the valve with the regulator according to this invention is bent or offset, the valve has a tendency to descend, rotate into one position, in order to achieve a different force moment on both sides of the valve. This affects the regulation moment acting upon the valve. If, however, the valve together with the connected lever is balanced in such a way that with varying positions and orientation there is no additional moment operating in a single direction of the rotation of the valve, the regulator can be used in any position.
  • valve's components can be preferably used; preferably, for example, the enlarged parts of the connecting element - connecting the valve's shaft with the valve's blade - will be used.
  • the increased head of the screw or blind closed matrix have a weight acting on the side opposite to the bending of the valve's blade. The static balancing of the valve together with the nonlinearly acting damping increase the accuracy of the desired constant flow.
  • valve's blade lacks shaped embossing for the insertion of the shaft, axis, but it is simply flatly screwed to the shaft by means of at least two flat head screws.
  • the screws have transition openings through which the valve's shaft runs.
  • the matrices can be used as a balancing matter, preferably the closed matrices with the blind opening will be used.
  • the flat heads of the screws are oriented to the side to which the valve's blade is bent; on the opposite side runs the shaft and the matrices.
  • an adjusting mechanism has a rotational damper which has a rotational arm connected with the valve's lever, whereby the damper is placed on the tiltably placed holder.
  • the holder rotates around the axis in order to achieve varying position of the damper against the axis of the valve's lever, which achieves different transmission ratio between the rotation of the valve's lever and rotation of the damper.
  • the rotational damper of the vibration with the arm is used; the damper is in the adjusting mechanism active only in certain angular scope; its ability of unlimited rotation is not used wholly. Thanks to the arm and the adjustable position of the holderer with the damper a varying transmission ratio between the valve and the rotational damper can be achieved.
  • the adjustable (changeable) transmission ration between the rotation of the valve and the rotation of the damper allows to suitable choose the size of damping at varying adjustment of the spring's prestress; that means that varying damping effect is achieved with variously set flows of the regulator.
  • the valve's lever or the arm of the damper In order to achieve a change of the position of the damper and in order to ensure the kinematic connection of the valve and the damper, the valve's lever or the arm of the damper have a radially oriented groove into which a pin - firmly attached on the second member of the gear - falls.
  • the pin moves in the groove during the change of the position of the damper, which changes the ratio of the semi-diameters of the valve's lever and damper's arm. From the point of view of simple construction it is preferable if the pin is firmly fixed in the valve's lever and the groove is produced on the damper's arm.
  • the adjusting mechanism has a valve's lever and a spring with the adjustable prestress, where the spring acts against the direction of the moment induced on the valve by the fluid during its flow through the channel.
  • the adjusting mechanism has an adjusting element for the change of the spring's prestress.
  • the adjusting mechanism has a damper and damper's holder.
  • the damper has an arm which is connected with the valve's lever for the transfer of the angular changes of the valve to the damper.
  • the damper is placed on the holder which is movably, preferably rotationally placed in the adjusting mechanism in such a way that the varying position of the damper against the position of the valve's axis is achieved for varying setting of the flow, which achieves various transmission ration between the valve's rotation and the rotation of the rotational damper.
  • Such adjustable transmission ration between the valve's rotation and the rotation of the damper can be achieved in such a way that the arm of the damper has a gate (coulisse) with a radially oriented groove into which the pin protruding from the valve's lever falls.
  • the possibilities of the choices of damping of the regulation valve can be imporved in such a way that the damper's arm does not have a radially oriented straight groove, but curved groove.
  • the choice of the shape of the groove allows to more precisely refine the transmission ratio between the rotation of the valve and the rotation of the rotational damper in the actual position of the adjusting element.
  • the shape of the groove can be designed in such a way that the gradual measurement of during variously set flows a necessary correction of the damping effect is found out and subsequently this correction is counted in terms of moving of the position of the pin on the valve's lever against the position of the damper's arm.
  • the position of the pin on the valve's lever is stable, the necessary correction is done through the change of the groove in the damper's arm.
  • the gathering of the data during multiple measurements provides us with an inde of the necessary curvature, deviation or angular rotation of the groove in the damper's arm.
  • the curved groove in the arm creates a closed coulisse or open curved fork.
  • a shape of the groove proved preferable, which consists of two continuous sections.
  • the first section of the groove is during the rotation of the arm led by straight line which is sloped against the radial line at least by 15°, preferably 22° to 23°.
  • the straight line starts at point A which is the initial middle point of the groove on the side by the axis of the rotation of the arm, and which is present on the radial line, and continuous to the point B which is outside the radial line and it is a middle point of the groove at the end of the straight line.
  • the radial line runs through the axis of the rotation of the arm and the point A.
  • the second section of the groove is led by the curvature which continues from the point B to the point C which lies away from the radial line, whereby the point C is against the radial line in the opposite semiplane as is the poin B, and whereby it forms a middle point of the ending of the groove on the side opposite to the axis of the arm's rotation.
  • the curvature can be part of the circle, ellipsis, hyperbole or it can have another basically continuous character.
  • a cylindrical ring or a bearing can be mounted on the pin, thanks to which the friction between the groove and the pin decreases.
  • the cylindrical ring or bearing rotates on the pin and rolls on the edge of the groove.
  • the holder of the damper can be arranged in such a way that at some of its positions, for example in a position with the maximum flow, the transmission ration between rotation of the valve and the rotation of the rotational damper close to 1:1.
  • the holder can in such arrangement be place in such a way that in the said extreme position the axis of the damper is close to the axis of the placement of the valve or in the axis of the placement of the valve.
  • the valve's lever acst on the damper's arm by means of a pin.
  • the geometry of the kinematic relationship between the damper with the arm with the curved groove and between the valve's lever also causes that the transmission ration, that is, the angular transmission between the rotation of the valve and the rotation of the damper is changed even if the position of the holder with the damper stays the same.
  • This change of the transmission ratio is smaller than the change of the transmission ratio caused by eventual change of the position of the damper against the axis of the valve's rotation and this follows from the use of the lever gear and from the use of the curved groove.
  • Desired nonlinearity of the damping or damping's hysteresis, respectively, can be eventually achieved or affected by the choice of the pin's gap in the arm's groove.
  • the pin can have a small gap sufficient for the smooth operation of the gear, but intentional increase of the gap by setting of larger breadth of the groove in a given place of the groove can ensure desired course of the damping in a given coposition of the valve and the holder of the damper.
  • a holder of the damper has been invented as reliable and simple for construction, which is rotationally or tiltably, respectively, placed in such a way that the circle or its part, respectively, which discloses possible points in the axis of rotation of the damper at various positions of the damper, runs through the axis of the valve or in the vicinity of its axis, respectively. It can be an extreme position corresponding to the maximally set flow of the regulator.
  • the holder with the damper is rotated in such a way that the axis of the damper distances itself alongside the circle from the axis of the valve's rotation.
  • the adjusting element for the change of the prestress of the spring is connected by the gear with the damper's holder.
  • a linearly acting draw spring is used, which is on one end connected to the valve's lever and on the other end it is connected to the adjusting element.
  • the adjusting element alters the spring's prestress, it has a lock of the set position and preferably it has a display, too, or the scale of adjustment, respectively.
  • a toothing can be used or - which proved to be preferable during inventing - a simple lever gear.
  • a stud for example, on the circumference of the rotationally adjusting element is a stud (stub, journal) which acts in the opening or in the groove on the holder of the damper.
  • the holder of the damper is placed tiltably and during the adjusting of the desired position of the adjusting element the angular rotation of the damper's holder changes, too, and this changes also the position of the damper against the axis of the rotation of the valve.
  • the change of the setting of the spring's prestress is by this coupled with the necessary change in the damper's position.
  • a base plate attached from the outer side of the channel's body is preferably used for the placement of the holder with the damper and the adjusting element with the spring. Between the body of the channel and the plate an insulation is inserted in order to reduce the transfer of the heat and noise.
  • the proposed invention by its simple, operationally reliable construction allows modularly design and produce regulators which supress the undesired vibrations, lower the hysteresis when the entry conditions change, mainly during the decrease or increase of the entry air pressure.
  • the described invention ensures reliable regulation of the constant flow of the fluid even in cases of larger cross-sections.
  • the adjusted flow is maintained with desired accuracy when the pressure decreases or increases on the entry side of the regulator, too, and the reaction of the valve to the changing entry pressure is quick and without vibration tail.
  • the advantage is also its simple and reliable construction when the adjusting mechanisms tested for the smaller cross-sections are used. Nonlinear acting of the spring and the damper ensures repeatedly accurate maintaining of the set flow without problems with the hysteresis of the system and it prevents vibrations.
  • Adjusting mechanism is adaptable for a broad scope of the cross-sections of the regulator; the independent valves can adapt to the changes of the entry pressure conditions independently for the conditions in their environment.

  • the axis of the adjusting elment 4 is rotationally mounted in the opening of the base plate and in the opposite opening in the casing.
  • the adjusting element 4 has first, longer arm on whose end it has two openings for the attachment of the spring 3 . On the first arm the matrix is pressed into which the lock's screw enters.
  • the lock's screw connects the adjusting element 4 with the casing by means of a friction joint, whereby in the casing a groove 9 is led arc-like and there is also an opening for the determination of the set popsition on the basis of scale in the adjusting element 4 .
  • the casing in this example of realization transfers the force from the adjusting element and from the spring and it is thus produced as a sufficiently strong pressing with a guiding for the accurate locking into the bent edges of the base plate.
  • the second, shorter arm on the pressing of the adjusting element 4 is ended by the stud 11 which falls into the fork in the holder 6 of the damper 5 .
  • the prestress of the spring 3 changes and at the same time the stud 11 rotates the holder 6 through the fork.
  • the damper 5 distances itself from the valve's 1 axis, which changes the transmission ration between the valve 1 and the damper 5 , too; the damper 5 now acts against the changes in valve's 1 position with a smaller damping effect.
  • the regulator has three regulation zones with three valves 1 and two partitions 8 in the channel's body.
  • a servomotor is attached to the casing of one adjusting mechanism 16 ; the servomotor's output shaft with the foursquare cross-section falls into the opening in the adjusting element 4 .
  • the servomotor changes the gear of the adjusting element 4 pursuant to the instructions from the central system of control in a building. Thanks to tw draw rod 12 the first, second and third adjusting mechanisms 16 are coupled in order to achieve the same position of the adjusting element 4 .
  • the regulation of the rotation of the three valves 1 itself is further controlled by the mechanism, without electronic circuits as in example 1 .
