Definitions

  • the present invention relates to a valve, in particular a servo valve, with a valve housing, a main valve and a pilot valve that can be actuated via a push-push mechanism for adjusting the main valve between an open and a closed position.
  • Valves of this type are used in various areas of technology, in particular for controlling fluid flows, for example in sanitary fittings or other applications.
  • a main valve is disposed within the valve body of the valve and is movable between open and closed positions to control fluid flow.
  • Valves that often require comparatively large amounts of energy to actuate the main valve use a smaller pilot valve to adjust the main valve, which, supported by the operating pressure of the fluid flow to be switched, allows the main valve to be switched with a lower energy requirement.
  • the pilot valve is actuated by manual actuation of a push-push mechanism, via which the pilot valve can be adjusted between two switching positions, which means that the main valve can also be adjusted between its closed position and an open position leaves.
  • EP 3 593 022 A1 it is known from EP 3 593 022 A1 to provide a push-push mechanism with three switching stages for actuating a pilot valve, in which a first switching stage of the fully closed position, a second switching stage of the fully open position and a third switching stage of an intermediate position is equivalent to.
  • the three switching levels can be switched through one after the other and in this way an intermediate position of the fluid flow can also be set.
  • this type of valve allows graduated quantity regulation, handling has proven to be disadvantageous due to the multiple actuation of the push-push mechanism required and is often found to be awkward by the users of conventional sanitary fittings, for example.
  • Another valve with a flow rate regulation is known from EP 3 740 708 A1, in which a sleeve-shaped control element surrounding the manual control element of the push-push mechanism is provided, via which a pressure piece of the push-push mechanism can be adjusted via a latched stop line leaves.
  • the push-push mechanism can be used to switch back and forth between the closed position and the open position.
  • the flow rate in the open position can be adjusted by twisting the sleeve surrounding the push-push mechanism. This is achieved via two stop points formed on the sleeve, which interact with two stop lines provided on the manual control element and have a filigree detent and limit the axial mobility of the manual control element at certain points.
  • valve actuation has also proven to be cumbersome in practice, since a first manual control element is required to actuate the push-push mechanism and a second, sleeve-shaped manual control element is required to adjust the flow rate.
  • Another disadvantage of this valve is that due to the fact that the stop points only touch the associated stop lines at certain points, there is a risk of increased wear, which can prove to be disadvantageous in particular in the case of valves that are adjusted daily over a very long period of time, for example in a sanitary fitting.
  • the invention therefore sets itself the task of specifying a valve in which volume regulation is possible in a user-friendly manner that is less susceptible to wear.
  • a valve of the type mentioned at the outset in that two adjusting disks are provided which are arranged such that they can be rotated in relation to one another in order to set the open position.
  • the setting of the open position and thus the volume regulation can be carried out in a user-friendly manner via the adjusting discs.
  • the actuating discs can lie flat against one another over large parts of their actuating range and transmit the required actuating forces. A punctiform contact of the components loaded by the actuating forces or the spring force of the push-push mechanism is avoided, resulting in a favorable construction that is less susceptible to wear.
  • the adjusting disks form a pair of lifting disks.
  • the pair of lifting discs can be operatively connected to the push-push mechanism.
  • the advantage of a pair of lifting discs is that by mutually rotating the adjusting discs, the corresponding rotary movement can easily be converted into an axial movement that can be used to actuate the push-push mechanism.
  • the setting disks have inclined setting surfaces.
  • a rotational movement can be converted into an axial movement via the sloping shelves.
  • the transmission ratio between the rotary and axial movement can be set via the angle of the sloping shelves.
  • self-locking can be achieved via the angle, so that the adjusting disks always maintain their rotational position and unintentional turning back is prevented.
  • a structurally advantageous embodiment provides that the adjusting disks each have two adjusting surfaces. This allows the actuating forces to be transmitted evenly. The required actuating forces are also distributed over two storage areas. There is little wear.
  • stops for limiting the rotational movement are arranged between the respective two shelves. Over-tightening is prevented by the stops. The angle of rotation is limited to an angle of less than 180°. The stops advantageously define the maximum flow rate and the minimum flow rate in the open position of the main valve.
  • a particularly advantageous embodiment also provides that the adjusting discs are arranged on an adjusting attachment which is detachably arranged on the valve housing and/or the push-push mechanism and via which the open position for regulating the flow rate can be adjusted.
  • the flow rate of the valve can be set in a simple and user-friendly way using the adjustment attachment. Due to the detachable arrangement on the valve housing and/or the push-push mechanism, the control attachment can also be easily retrofitted to valves without flow control. In particular, it is not necessary to dismantle an existing valve in order to subsequently equip it with a flow rate control.
  • the control attachment can be retrofitted to an existing valve in just a few simple steps.
  • the push-push mechanism can be operated via the positioning attachment.
  • the positioning attachment has a dual function.
  • the open position of the main valve for regulating the flow rate can be adjusted via the adjustment attachment.
  • the pilot valve and the main valve can be switched between its open and closed position via the adjusting attachment.
  • the positioning attachment is designed in such a way that it can be operated with one hand, both for actuating the push-push mechanism and for regulating the quantity.
  • a manual control element is provided, with the push-push mechanism being operable by pressing the manual control element and the open position being adjustable by rotary actuation of the manual control element.
  • the manual control element can be an element that can be touched directly by the operator's hand. Alternatively, it can also be an element on which, for example, a chrome-plated actuating button of a sanitary fitting is attached.
  • the manual control element can be part of the positioning attachment.
  • the manual operating element can be actuated by pressure in the pilot control direction of the pilot control valve and/or along the main valve axis of the valve. A reset can take place via a return spring.
  • the open position of the main valve can be adjusted by rotating the manual control element.
  • the rotary actuator can be designed in such a way that the flow rate is reduced by turning in one direction and the flow rate is increased by turning in the opposite direction. In particular, it can be provided that the flow rate is increased by turning to the left and reduced by turning to the right, which the operator is familiar with from other applications and in this respect allows an intuitive volume regulation.
  • an adjusting disk is releasably connected to the push-push mechanism.
  • the adjusting disk can be placed on a pressure piece of the push-push mechanism.
  • the connection between the adjusting disc and the push-push mechanism can be made by clamping, latching and/or positive locking.
  • the adjusting disk can have a recess that corresponds to the outer contour of the pressure piece of the push-push mechanism. It is important that the adjusting disk is connected to the push-push mechanism in a non-rotating manner.
  • a configuration that is advantageous in terms of assembly provides that an adjusting disk is arranged on the manual control element. In this way, the adjusting disk can be arranged on the valve together with the manual control element in one assembly step.
  • a configuration that is advantageous in terms of production technology provides that the adjusting disk is connected in one piece to the manual control element.
  • the adjusting disc can be injection molded in one piece onto the manual control element, for example in an injection molding process. This reduces the number of parts and also the assembly work.
  • a further advantageous embodiment provides that the manual control element is connected to the valve housing, in particular with a snap-in connection.
  • the manual control element is supported in relation to the valve housing via the connection to the valve housing.
  • An advantageous embodiment provides that it is a snap-in connection.
  • the manual control element can be connected to the valve housing without the use of tools due to the snap-in connection of the manual control element to the valve housing.
  • a further advantageous embodiment provides that the manual control element is connected to the valve housing in such a way that it can be moved axially in the direction of the push-push mechanism against the force of a tensioning spring and can be rotated relative to the valve housing. By applying a compressive force to the manual control element, it can be moved axially against the force of the tensioning spring. This axial movement can be used to actuate the push-push mechanism. Due to the arrangement of the manual control element that can be rotated relative to the valve housing, the open position of the main valve for regulating the flow rate can be adjusted by turning the manual control element.
  • the manual control element has latching elements which are latched with a latching structure arranged on the valve housing. The locking elements can be integrally formed on the manual control element.
  • the latching elements are formed on resilient tongues.
  • the tongues equipped with the locking elements form locking tongues.
  • peripheral areas of the manual control element cannot contribute to the latching.
  • the cylindrical manual control element is divided into tongues at regular intervals in one end region, with approximately every second, third or fourth tongue being designed as a latching tongue.
  • the locking structure arranged on the valve housing it has proven to be advantageous if this is designed as a circumferential locking collar.
  • the locking collar can be arranged circumferentially over an angular range of 360° over the entire circumference of the valve housing.
  • the locking collar can be an annular projection.
  • Stabilizing elements extending in the axial direction can be arranged above the latching collar, which rest against the inside of the manual control element and guide its axial and rotary movements.
  • the manual control element is reliably returned to its initial axial position by the tensioning spring.
  • the manual control element is always in the same axial position after it has been operated. This is also beneficial to the ease of use.

  • FIGS. 1 and 2 show a perspective and partially sectioned view of a valve 1 designed as a cartridge valve. It is a servo valve such as is used in the sanitary sector, for example in shower fittings.
  • the valve 1 has a valve inlet 20 and a valve outlet 21 arranged coaxially thereto. In that regard, it is a coaxial valve.
  • a main valve 3 is arranged, which is shown in Figs. 1 and 2 in its open position. In this position, an annular gap arranged between the closing element 22 of the main valve 3 and the valve seat 23 of the main valve 3 opens the flow path between the valve inlet 20 and the valve outlet 21 .
  • the closing element 22 is a closing membrane, the position of which can be controlled via a pilot valve 5 with a smaller diameter.
  • the pilot valve 5 has a movably arranged pilot element 5.1, which interacts with a control opening 22.1 of the closing element 22.
  • the pilot control element 5.1 is designed in the manner of a magnetic plunger and interacts with a magnet 18 designed as a permanent magnet.
  • the pilot control element 5.1 is magnetically coupled to the magnet 18.
  • the magnet 18 is operatively connected to the push-push mechanism 4 . By actuating the push-push mechanism 4, the magnet 18 is moved along the valve axis A of the valve 1. Due to the magnetic coupling, the pilot control element 5.1 follows this movement and can in this way be switched bistable between two end positions by actuating the push-push mechanism 4.
  • the pilot control element 5.1 closes the control bore 22.1 of the closing element 22 with a sealing surface 5.2.
  • the closing element 22 is pressed onto the valve seat 23 by the pressure of the fluid present and seals it in a fluid-tight manner.
  • the magnet 18 is transferred to its other stable end position.
  • the pilot control element 5.1 magnetically coupled to this is taken along and releases the control opening 22.1.
  • the fluid can now flow from a pressure chamber 24 arranged above the closing element 22 via the control opening 22.1 into the valve outlet 21, as a result of which the pressure conditions inside the valve 1 change in such a way that the closing element 22 is raised above the pressure of the fluid present.
  • the pilot control element 5.1 forms a hydraulic stop that limits its stroke.
  • the closing element 22 is initially raised by the pressure of the fluid present at the valve inlet 20 until it comes into contact with the sealing surface 5.2 of the pilot control element 5.1 positioned above it.
  • the control bore 22.1 is thereby briefly closed and the closing element 22 is moved in the opposite direction by the pressure building up above the closing element 22 until the control bore 22 is opened again.
  • a kind of oscillating movement of the closing element 22 results, with the result that, after a few oscillations, the closing element 22 is in a floating state just below the pilot control element 5.1.
  • the resulting position of the closing element 22 depends on the axial position of the pilot control element 5.1 and has a direct influence on the flow rate of the valve 1.
  • the flow rate flowing through the valve 1 can therefore be regulated via the axial position of the pilot control element 5.1 of the pilot valve 5, which acts as a hydraulic stop.

This movement is transmitted to a pressure piece 4.1 of the push-push mechanism 4 and used to switch the valve 1 between the open position and the closed position of the main valve 3. During this movement, the latching elements 14 lift off from the latching structure 15 in the direction of the push-push mechanism 4 . After the push-push mechanism 4 has been operated, the operator removes his hand from the manual control element 7. The manual control element 7 is reset to its initial position.

  • the valve 1 described above is characterized by easy handling and low wear.
  • the push-push mechanism 4 can be actuated via the manual control element 7, ie the main valve 3 can be switched back and forth between its open and closed position. Due to the adjusting disks 8, 9 provided as adjusting elements, the adjusting forces are transmitted in a favorable manner and there is therefore less wear.
