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 essentially emptied state of the storage space or the area upstream or downstream of this actuates 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 located 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 in the most varied of locations in the storage system, for example in the storage space, there in the region of the bottom point or in the region of various depressions, and there is also the possibility of arranging 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 locking position.Finally, it is also conceivable to place the float in the area downstream of the storage space, for example in a downstream shaft or to arrange the drainage path, or even in a flow path that is connected in parallel to 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 limits the upward movement of the float acting on the hydraulic system. 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 trigger always works 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 the check valve.
  • This can be done mechanically via a transmission line, for example, by lifting the spring-loaded closure cone, which is usually arranged in a non-return valve, from the closure opening and thereby making the non-return valve pass through in two directions, which leads to the sudden lowering of the float and triggering of the closing mechanism of the butterfly valve. It can also be done by providing a bypass line in the area of the check valve with the closure valve located therein and triggering the release valve in any manner when the specific liquid level is reached and thus opening the bypass line previously closed.
  • 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, control levers for opening or closing the shut-off 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 device triggers the next butterfly valve in a defined manner, the next flushing event follows, etc.

  • the diameters of outlet 4 and throttle opening 8 are coordinated with one another in such a way that a larger volume flow can be passed through the throttle opening 8 than through outlet 4.
  • 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.
