Definitions

  • the invention relates to a method for actuating the closing mechanism of a float-controlled shut-off valve of a rinsing chamber for rinsing a liquid storage space, in which the float, preferably located in the area of the bottom of the storage space or a region upstream or downstream of the storage space, has a float arm and a float body in the substantially empty state of the storage space or the latter upstream or downstream area actuated the closing mechanism of the butterfly valve; also a device for performing the method.
  • Liquid storage spaces with one or more flushing chambers which are preferably arranged in the area of a bottom high point of the storage space and which can be filled with storage liquid and which let the storage liquid run out as flushing surge when the storage space is empty, are used wherever intermittent quantities of liquid are initially collected and passed on with a delay in order not to overload subsequent facilities.
  • Liquid storage rooms of this type are frequently used as rain retention basins, rain clarifiers, rain overflow basins and damming channels for wastewater disposal.
  • Each butterfly valve is assigned a float located in the area of the bottom of the storage space, the transfer of the float movement to the closing mechanism of the butterfly valve takes place according to the fluid level in the drainage area via wire cables, Bowden cables, hydraulically through the interaction of float-side and butterfly valve-side hydraulic cylinders or in another suitable manner .
  • the rinsing chamber By controlling the flushing processes of the rinsing chamber and the rinsing processes of the storage space by the float, the rinsing chamber is automatically filled without external energy at the beginning of the damming process and is rinsed with a strong flushing surge after the storage space has run dry. All flushing processes are carried out with collected storage liquid, so that there are no operating costs.
  • the object is achieved by a method of the type mentioned, which is characterized in that when the space in which the float is emptied, a lowering movement of the float for actuating the closing mechanism is prevented and the movement of a release means is used to fix the float arm to release the locking mechanism.
  • the float arm is preferably prevented from lowering further when a defined liquid level is reached and is only released when the essentially empty state of the storage space or the upstream or downstream region is reached.
  • the triggering means can likewise be controlled by means of a float, but can also be pressure-controlled, in particular by means of the liquid pressure in the area of the bottom of the storage space or the upstream or downstream area. Depending on the local requirements, the control of the float and the release agent can take place with or without external energy.
  • the float preferably acts via a hydraulic system or directly on the closing mechanism, which suddenly releases the shut-off valve of the rinsing chamber, whereby the storage liquid runs out as a rinsing surge.
  • the float can be arranged at the most varied points in the storage system, for example in the storage space, there in the region of the bottom point or in the region of different depths
  • the float in the area upstream of the storage space, for example in a prechamber or an inlet section, with the advantage that when the liquid level rises, the float responds immediately and transfers the associated closing mechanism of the butterfly valve to the locked position
  • the float in the area downstream of the storage space, for example in a downstream shaft or the drainage section, or even in a flow section which is connected in parallel with the storage space.
  • the float and the float-controlled triggering means form a structural unit, it is of course necessary to arrange the two parts at the same point in the storage system.
  • the trigger is structurally separate from the float, great advantages can be achieved with regard to the control of the flushing process if it is connected downstream of the float, i.e. the float is preferably located in the area upstream of the storage space, in particular in a prechamber, and the trigger at least in the area of the bottom of the storage space or even in the area downstream of the storage space, in the latter case it is sufficient if the float is arranged in the storage space.
  • Preferred embodiments have the float and the triggering means, furthermore a first hydraulic power means, which is connected to the pivot point of the float arm of the float, and a closing mechanism for the butterfly valve, which can be actuated by a second hydraulic power means, which is actuated by the first power means connected is.
  • a pivotable support lever is provided in the pivoting area of the float, which is preferably arranged in the area of the bottom of the storage space or the upstream or downstream area, which can be pivoted by means of a spring into the pivoting path of the float arm and supports it, and in addition to this first float, a second float is provided, which moves the support lever from its position supporting the swivel arm of the first float when the liquid level drops via a driver.
  • the support lever and the second float are advantageously mounted on a common axis, the support lever should have a shoulder spaced from its pivot point with which the driver forming part of the float arm of the second float can be brought into engagement, the spring should be between the free end of the Approach and the float arm of the second float.
  • a second variant of the invention provides that the float arm consists of two articulated parts and a support lever is provided in the swivel area of the swivel bearing-side part of the float, which is pivotable by means of a spring in the swivel path of this part of the float arm and him supports, the other swiveling part of the float moves the support lever from its position supporting the swivel bearing part of the float when the liquid level drops via a driver.
  • a stop should be provided which follows the rising movement of the float acting on the hydraulic system limited above. This results in defined geometrical relationships between the support lever and the float arm acting on the hydraulic system, without having to take into account the maximum fill level of the storage space, since the float (s) can be stowed as desired.
  • the actual support of the float expediently takes place in that the support lever is pivoted into a slightly overstretched position with respect to the float arm acting on the hydraulic system and thereby abuts an attachment attached to this float arm.
  • the support lever is moved from its overstretched position, the float arm in operative connection with the hydraulic system drops suddenly and swivels the support lever against the force of the spring.
  • separate means should advantageously be provided.
  • the float is pivotally attached to the float arm and by means of a control rod which can be moved by the float body in the longitudinal direction of the float arm and can be pivoted with the float arm, an articulated rocker arm which can be moved into a position when the float body is raised can be actuated , in which it engages under a support arranged in the swivel range of the rocker arm, but releases the support when the float is lowered.
  • the float arm remains in its position as a result of the rocker arm resting on the support, while the float body drops and pulls the rocker arm out from under the support via the control rod.
  • the float arm drops suddenly and acts on the hydraulic system.
  • a float-controlled release means always interacts mechanically as a unit with the float.
  • this is not necessary, since it is provided there that a release means acts directly on the hydraulic system acted upon by the float for actuating the closing mechanism of the butterfly valve.
  • the triggering device can thus be placed anywhere in the flushing system, regardless of the float, in particular in the bottom of the storage space, the area upstream or downstream of it, for example in the bottom of the antechamber or in the drain area / drain shaft, while the float is preferably arranged in the bottom of the antechamber. to lock the butterfly valve as soon as liquid is stowed in the prechamber.
  • a check valve is provided in the hydraulic line between the float and the closing mechanism, which only allows a flow through the line in the direction of the float, thus allowing a stroke movement of the float when liquid is stowed. If the liquid level drops again, the non-return valve prevents the float from sinking according to the liquid level, so that it emerges from the liquid. Only when the liquid level at the location of the triggering agent has reached a defined decrease value does the triggering means, which is preferably controlled by float or liquid pressure, act the check valve.
  • a plurality of butterfly valves is controlled by a float-controlled triggering means. If, for example, with several existing butterfly valves, each butterfly valve has its own float and its own hydraulic line for triggering the closing mechanism of the butterfly valve, actuating levers for opening or closing the closing valve of the corresponding bypass line can be connected to one another by means of an adjustable linkage, so that it is only it is necessary to act on one of the control levers with the float-controlled trigger.
  • the adjustability of the linkage also has the advantage that the flushing events can then take place, that is, for example, when a certain low liquid level in the downstream chamber is reached, a shut-off valve is first triggered by the float-controlled triggering means, whereupon the liquid in the following first flushing event Storage space and thus also in the downstream chamber rises again, when the liquid level drops again below the certain low liquid level mentioned above, the float-controlled triggering means triggers the next shut-off valve in a defined manner, the next flushing event follows, etc.
  • FIGS 1 and 2 show an asymmetrically constructed rain basin 1 with inlet 3 and outlet 4, which is divided by a partition 19 into a prechamber 1a and a main chamber 1c.
  • a rinsing chamber 1b 'and 1b ⁇ are arranged on the right and left.
  • a throttle opening 8 in the area of the dry weather channel 2.
  • the inlet openings 11 in the wall 28 can be closed with a non-return flap 12, the shut-off flap 13 of the flushing opening 10 of the flushing chambers 1b ′ and 1b ⁇ are each by a shut-off flap 13 assigned float system 16, which is located in the main chamber 1c in the region of the bottom low.
  • the diameter of the outlet 4 and the throttle opening 8 are mutually coordinated so that a larger volume flow can be passed through the outlet 8 than through the outlet 4th
  • the water accumulated in the pre-chamber 1a penetrates through the inlet openings 11 into the rinsing chamber 1b 'and 1b ⁇ . If the liquid level drops after the rain event, the liquid is retained by the non-return flaps 12, and the rinsing chambers 1b 'and 1b ⁇ remain filled. If the main chamber 1c has run empty, then the float system 16 has sunk so far that the butterfly valves 13 are released again and rinsed.
  • Parallel to the dry weather channel 2, two guide profiles 7a and 7b are arranged, which guide the flushing surge to the side.
  • FIG. 2 shows the maximum fill level C of the liquid storage space at which the float system 16 is flooded many times over.

  • the float system 16 initially has a first float arm 17 which is pivotally connected at one end 18 to a base plate 6, which in turn is fastened to the end wall 9 on the outflow side (FIGS. 1 and 2).
  • the other end of the float arm 17 is provided with a float body 20 which acts as a buoyancy body.
  • a metal bellows 14 engages non-positively on it.
  • the end of the metal bellows 14 facing the float arm 17 has a threaded bolt 15 which passes through a pivot bearing 21 arranged in the float arm 17 and is secured and adjustable by self-locking nuts 22.
  • the end facing away from the float arm 17 has a flange 23 with a bore 24, a fastening means, not shown, passes through this bore 24 and serves to fasten the metal bellows 14 to the plate 6.
  • the metal bellows 14 as such consists of two metallic sleeves 14a and 14b which accommodate the actual bellows part 14c between them.
  • a metal ring 14d is fastened to the metal sleeve 14a, which in turn receives a metal sleeve 14e, the inside diameter of which is slightly larger than the outside diameter of the bellows part 14c, so that when the bellows part 14c is pressed together, its buckling is prevented.
  • the metal sleeve 14e is coated on the inside, which ensures largely friction-free sliding of the bellows part 14c in the metal sleeve 14e.
  • the opening 26 of the metal bellows 16 serves to vent it, the opening 27 is operatively connected to the closing mechanism 5 via a line 35 which conveys the hydraulic fluid.
  • float arm 30 As shown in FIG. 3, based on the orientation of the rain basin 1, there is a further float arm 30 below the float arm 17, which is pivotally connected to the plate 6 at one end 31 by means of a bolt 32 in accordance with the design of the float arm 17 , The other end of the float arm 30 carries a float body 33, which also acts as a buoyancy body.

  • the mode of operation of the previously described float system 16 is explained below, in particular with reference to the drawings in FIGS. 3 to 6, and it should be assumed that the liquid accumulates up to the maximum fill level C shown in FIG. 2 during a rain event.
  • the liquid level causes the float system 16 to be flooded many times over; the illustration in FIG. 3 shows the float bodies 20 and 33 approximately in an upper end position.
  • the rollers 37 attached in the support lever 36 are slightly spaced from the underside of the float arm 17 and abut against a stop 40 located on the underside of the float arm 17.
  • the arrangement of the stop 40 to the center of rotation of the support lever 36 is dimensioned such that the support lever 36 is in an overstretched position when it contacts the stop 40.
  • FIG. 4 shows the float body 33 in its position with the main chamber 1c almost emptied. Due to the movement of the support lever 36, the tension spring 39 is tensioned.
  • the float body 33 In the subsequent rain event, the float body 33 initially rises with the liquid level in the main chamber 1c; once it has reached approximately the level of the float body 20, both float bodies rise together until the upper float arm approximately reaches the position shown in FIG. 3. In this position, a further upward pivoting of the float arm 17 is either prevented by the maximum expansion capacity of the metal bellows 14, or a separate stop which comes into the pivoting path of the float arm 17 is provided. In the position mentioned, the underside of the float arm 17 is at least so far apart from the rollers 37 of the support lever 36 that the support lever 36 can be moved into the extended position in which it rests on the stop 40.

  • FIG. 8 shows a third embodiment of the float system 16, where the float body 20 is pivotably attached to the float arm 17, parts which correspond to the two previously described variants and are identical in their function are again identified with the same reference numerals for the sake of simplicity.
  • the float arm 17 is extended beyond its fulcrum 56, above the extended area the metal bellows 14 engages.
  • the end of the float arm 17 which receives the float body 20 is designed as a U-shaped profiled weight body 57 which surrounds the float body 20 on both sides and with its upper part 58 limits the swivel path of the float body 20 upwards.
  • a control rod 59 is articulated to the float body 20 and engages a plate 61 which is pivotably mounted by means of two parallel links.
  • the plate 61 receives a rocker arm 63 via a joint 62, the downward pivoting path of which is limited by a stop 64 arranged on the underside of the plate 61 in such a way that it is not possible to stretch the rocker arm 63 with respect to the plate 61.
  • a support 65 projecting into the pivoting range of the rocker arm is arranged above the rocker arm 63 shown in stretched fashion.
  • the float body 20 In the event of a rain, the float body 20 floats and comes into contact with the upper part 58 of the weight body 57. If the liquid level drops, the float arm 17 pivots into the position shown in FIG. 8 and the rocker arm 63 comes into contact with the support 65 As the level of liquid continues to drop, the float body 20 swings down and moves the control rod toward the free end of the float arm mes 17, so that the rocker arm 63 is pulled out from under the support 65. The float arm 17 swings suddenly downward, the extended area compresses the metal bellows 14 located above in this variant, which in turn actuates the closing mechanism 5.
  • the rocker arm 63 In the lowered position of the float arm 17, not shown, the rocker arm 63 is indeed in one plane with the Control rod, but points obliquely upwards.
  • the float body 20 When the rain event occurs again, only the float body 20 initially floats and thus reaches the upper part 58 of the weight body 57, in the event of a further liquid accumulation the float arm 17 then swivels together with the float body 20.
  • the rocker arm 63 Once the float arm 17 has reached the position shown in FIG the rocker arm 63 is in the position shown in dashed lines due to the support 65 located in the meantime.
  • FIG. 9 shows a liquid storage system which essentially corresponds to that shown in FIG. Corresponding parts which are identical in their function are again identified with the same reference numerals for the sake of simplicity. The variant according to FIG. 9 differs from that according to FIG. 1 by the arrangement of the spatially separated float system 16a and 16b.
  • the float system 16a which is arranged in the prechamber 1a, consists essentially of two independently operating main floats, that is, each of the float arm 17 and the float body 20 together with the associated force transmission means for the butterfly valve.
  • the float arms 17 of the floats are each articulated parallel to the corresponding longitudinal wall of the prechamber 1a, while the float system 16b comprises this float-controlled triggering means, thus the auxiliary float, which is arranged in the outlet area 1d downstream of the main chamber 1c.

  • the control element 70 and its function is particularly clear from FIG. 10. It is designed as a check valve, which is connected to the float-side line 35 'or the butterfly valve-side line 35', which is blocked when pressure is applied to the line 35 'and thus prevents a lowering movement of the float body 20, however, a lifting movement of this float body allows.
  • the control element is designed as a conventional check valve 77, the closure element 71, which is designed as a cone, is prestressed into the likewise conical passage opening by means of a compression spring 72.
  • the closure element 71 is articulated to the pivotably mounted float arm 30 of the float system 16b, which can thus lift the closure element 71 from its seat upon a corresponding movement and cancels the non-return function of the control element 70.
  • the float arm 30 pivots and causes the valve 75 to be moved into its open position via the pivoting movement, so that the hydraulic fluid can flow past the check valve 70 via the bypass line 70 and the float system 16a suddenly unlocks the butterfly valves 13.
  • two separate valves 75 associated with float systems 16a are provided, each having an adjusting lever 76, between which an adjustable linkage 77 is arranged. Due to the adjustability of the linkage 77, different opening times of the butterfly valves 13 can be achieved, which can be illustrated particularly in the illustration of FIGS. 9 and 11.

  • the support part 44 is mounted in the flap housing 29 via a threaded bolt, so that the shut-off flap 13 can be adjusted with respect to the flap housing 29. This is of great importance because, depending on the accumulation height in the rinsing chamber, large hydrostatic pressures can act on the butterfly valve 13 and only if the sealing body 47 is fitted exactly will the butterfly valve 13 be sufficiently tight.
  • the locking mechanism 5 assigned to the butterfly valve 13 has a corresponding metal bellows 48, the opening 49 of which is connected to the line 35, so that a compression of the metal bellows 14 leads to a corresponding expansion of the metal bellows 48.
  • the flange of the metal bellows 48 is connected to the valve housing 29, the metal sleeve located on the side of the metal bellows 48 facing away from the opening 49 receives a connecting member 50 which is connected to a locking rod 51 for the latching lugs 45 of the butterfly valve 13.
  • FIGS 12 to 14 show details of the locking mechanism 5.
  • the plate-shaped locking rod 51 is at two, spaced apart locations between two guide rollers 53 slidably in the longitudinal direction.
  • the guide rollers rotatably mounted in the flap housing 29 take up the narrow side of the locking rod 51 between their flanks, the locking rod 51 has on its side facing away from the flap housing 29 two locking plates 54 arranged obliquely to the longitudinal extension of the locking rod 51, at the free ends of the locking lugs 45 on the shut-off valve side each have a rotatable locking roller 55 attached.
  • leaf springs 66 which are attached to the bearing housing 29 and are designed in accordance with the shape of the latching lugs 45 ensure a positive connection Engagement with the detents 45 ( Figures 12 and 14).
  • the metal bellows 48 contracts and the locking rod 51 is moved together with the locking plates 54 - additionally supported by the spring 52 - in the direction of this metal bellows, the locking plates 54 engage behind the again Locking rollers 55 and press the sealing flap 47 of the shut-off flap 13 against the flap housing 29.
