Definitions
- the invention relates to a control arrangement for an actuatable by negative pressure Shut-off valve, intended for a vacuum sewage system, comprising one of a back pressure that can be actuated by accumulated water, a negative pressure leading connection closing or opening first valve, one over the first valve pressure-adjustable chamber, in or adjacent to this a preferably Main piston acted upon by a spring is arranged displaceably depending on the pressure in the chamber, a vacuum connection is controllable to at least the shut-off valve, at least one of which Main piston independent, but with this preferably via a driver Forcibly connectable second valve is provided, via which the shut-off valve with negative pressure is acted upon.
- a corresponding vacuum sewer system comprises house connection shafts as essential components with a currentless control arrangement and shut-off or Suction valves, a subsequent pipe system with systematically arranged High and low points as well as a vacuum station with waste water collection tanks, waste water pumps, Vacuum pumps, measurement and control technology.
- the wastewater first flows out of buildings via standard free fall house connection lines to a e.g. located on a property border, in which the exclusively pneumatically controlled shut-off valves and the associated control arrangement are accommodated.
- the mechanism present in the control arrangement ensures that it is present a shut-off valve opens the shut-off valve and the waste water into the Vacuum line suctioned off. Depending on the time, the valve closes after a few seconds Spring force and vacuum.
- the wastewater itself collects at the lowest points in the pipe system and is used by air flowing in gradually over the following high points towards the Vacuum station pushed.
- the vacuum tank will then become that Wastewater with conventional wastewater pumps via a pressure or free fall line Wastewater treatment plant funded.
- the control arrangement assigned to the shut-off valve should be an automatic one Adapt to the wastewater portions to be extracted and to the operating conditions in the Enable drainage system.
- Another disadvantage is that opening the vacuum to the shut-off valve releasing second valve can be done at low vacuum, but that not sufficient for suction. This increases the risk that wastewater in the Frost area of the pipe can be raised and freeze there.
- a control arrangement of the type mentioned can be found in DE-A-37 27 661.
- Time control at least one control valve and possibly a minimum vacuum valve necessary. Due to the complex mechanical structure, in particular of the time control device, which, among other things, a membrane piston with a hollow pin, which is in a Guide bush is guided, and includes a bracket, which in turn on a swiveling actuating lever acts to close the weight-loaded control valve opening or closing, it is not always guaranteed that the control arrangement with the required reliability works.
- the known control arrangement can either a control valve or a second control valve arranged downstream thereof are operated, which together control a single shut-off valve.
- the present invention addresses the problem of a control arrangement of the type described at the outset in such a way that compact and constructive simple construction a high level of operational safety is guaranteed, with the Main piston a vacuum connection is not only controllable to a shut-off valve.
- a vacuum connection is not only controllable to a shut-off valve.
- at least two valves are preferred one for wastewater and one for air that can be controlled at the same time overlapping or one after the other with the vacuum required to operate be charged.
- control arrangement has a third, a connection to another shut-off valve or air into the vacuum sewage system supplying aeration valve controlling valve that with the Main piston can be positively coupled.
- the control arrangement according to the invention can be used universally, i.e. depending a desired application of the other valves actuated by the main pistons can be done.
- the control arrangement basically has at least two more Valves, the various other valves, e.g. Shut-off valves for waste water and can control ventilation valves independently of each other.
- the second and third valves are independent of one another, but are connected in parallel.
- the main piston starts a further fourth, preferably displaceable along its longitudinal axis Valve off, depending on the position of the main piston to the chamber Closes or releases negative pressure connection.
- the other part closes Valve the chamber opposite the connection when the main piston passes through increased vacuum in the chamber has been moved, especially if a negative pressure prevailing in the chamber a displacement of the main piston in the direction of the first valve.
- the further valve reproduces the connection free when the main spool has moved back to the basic position, i.e. when in the chamber is compensated for pressure with the environment.
- the further fourth valve is preferably quasi telescopic to the main piston slidably, the further valve with its piston guided in the main piston is arranged.
- control arrangement have the second and third valves parallel to each other and parallel to the main piston extending second and third valve pistons, which preferably from each other have different lengths or are adjustable in length.
- the main piston then acts at least on the second or third valve piston a driver such that when the main piston of its through in the vacuum acting position moved to its basic position returned, depending on the lengths of the second and third valve pistons or as a function of positions of the second or third valve pistons outgoing and interacting elements with the driver the second or third valve is opened to the required vacuum to the suction or To direct the ventilation valve.
- the second and third valves then close again, if, when the main piston slides back, its driver with the second or third valve piston comes out of reach.
- the element emanating from the respective second or third valve piston preferably a flexible design at the end of the valve piston and at least peripherally Element such as disc element, the recesses or projections in the Carriers of the main piston are assigned.
- the positive coupling between the Main piston and the second and the third valve piston is carried out such that the second and third valve opened or closed at different times become.
- the compact structure of the control arrangement results in particular from the fact that it comprises a cylindrical housing, the first of which is displaceable along its central axis Valve with its valve piston, the main piston and the other coaxial to the main piston Slidable valve pistons are arranged that the main piston in known Way is held by a membrane, which can be acted upon by negative pressure Chamber is pressure-tight on a side that is preferably opposite the first valve closes, and that e.g. radially on the main piston or the fourth valve at least a limiter acts in such a way that the main piston moves increasing vacuum or a closing of the fourth valve only at a predetermined Vacuum occurs in the chamber.
- the limiter can be spring loaded and acting radially on the main piston or piston of the fourth valve Ball elements can be formed, which at least in a preferably circumferential recess How groove can be snapped in when the main piston is in or near its position at ambient pressure in the chamber.
- control arrangement only responds if if there is a vacuum in the vacuum sewage system that is sufficient to To promote wastewater to the extent and quantity required.
- the limiter can also be designed as a magnet, in the sense shown above to act.
- connection which can be closed by the first valve or the further fourth valve, via which the negative pressure is passed to the chamber is also preferably as a line running in a wall of the housing is formed.
- the currentless, but pneumatically operating control arrangement (10) comprises a cylindrical one Housing (12), in which a first valve (14) or release valve is arranged, via a membrane (16) from an opening (18) into the housing (12) back pressure is applied.
- the trigger valve (14) extends with its valve piston (20) along the longitudinal axis the housing (12). There is also a main piston (22) along the longitudinal axis. displaceable, the larger with a coil spring (24) acted upon Section (26) in a chamber (28) performing a timer function is.
- the chamber (28) is on the side opposite the release valve (14) sealed a membrane (30) which is connected to the main piston (22).
- the spiral spring (24) extends between a flange-like section (32) of the Main piston (22) and an intermediate wall (34) of the housing (12), the one central opening (37) which runs concentrically to the longitudinal axis of the housing (12) has, on the one hand, via a valve disk (36) of the valve piston (20) of the release valve (14) compared to a pressurizable and within the Housing wall extending line (38) and on the other hand via a valve plate (40) a closure valve (42) can be closed, the piston (44) of which is coaxial Main piston (26) is displaceable and is guided by this.
- the valve piston (44) of the closure valve (42) and the main piston (22) form a kind Telescopic linkage.
- a rod-shaped section (46) of the main piston (22) which is preferably made of stainless steel.
- the section (46) is within a bore (48) of a further intermediate wall (50) of the housing (12).
- the force acting on the section (46) via the balls (54) adjustable via spring elements (56), which in turn are accessible via externally accessible adjusting elements (58) can be preloaded.
- Preferably three spherical elements are uniform distributed over the circumference of the section (46).
- the function of the limiter (52) occurs when the balls (54) are rotating Groove (60) in the section (46) are engaged. This is the case if the main piston (22) is in a first, lower end position. Only if In the chamber (28) there is a sufficiently strong negative pressure, the main piston can (22) can be moved up in the exemplary embodiment.
- the piston section (46) of the main piston (22) extends in a lower chamber (62) of the housing (12) of the control arrangement (10) and has a radially extending disc element (64) acting as a driver with openings (66) and (68).
- the switching valves (70) and (72) set in Depending on their positions, a connection to a pressurized vacuum Line (74) and connections (76) and (78).
- the connections (76), (78) are preferably in the form of a valve which can be actuated by negative pressure Suction valve (connection 76) or a ventilation valve (connection 78) of a vacuum sewage system connected to waste water with the necessary for transportation To promote amount of air.
- the switching valves (70) and (72) have valve pistons (80) and (82), which at their in ends of the chamber (72) extending disc-shaped elements (84) and (86) have at least peripherally elastic.
- the extension of the Elements (84), (86) is connected to the openings (66) and (68) of the driver (64) of the main piston (22) adapted such that the elements (84), (86) on the one hand Openings (66) and (68) when fully closed or fully open Push through switching valves (70) and (72), but then from the driver (64) be detected and carried when the main piston (22) in below described type of a second (upper) end position shown in FIG moved its first and Fig. 1 end position.
- Fig. 1 the control arrangement according to the invention is shown in a position in which the main piston (22) is in its lower (first) end position. It also says a back pressure does not apply to the membrane (16) via the opening (18). At over the Connection (74) applied vacuum are both the trigger valve (20) and Switching valves (70) and (72) closed. As a result, chamber (28) prevails the connections (76) and (78) to the suction valve or ventilation valve, ambient pressure, so that the latter are closed; because on the one hand the lower chamber (62) of the Housing (12) via an opening (94) connected to the environment and on the other pass through the valve pistons (80) and (82) of the switching valves (70) and (72) receiving guides in the partition (50) with play. In addition, you can the valve pistons (80) and (82) each have a slot, not shown, the length of which is such that when the valves (70) and (72) are closed, a connection between the chamber (62) to the connections (76) and (78).
- shutoff valve (42) can move toward the main piston (22)
- the closure valve (42) continues to close the opening (37) because it is over the Line (38) pending negative pressure is kept in the closed position ..
- the disk-shaped element becomes (84) of the switching valve (70) from the driver (64) with the result that the Switching valve (70), which controls the suction valve via the connection (76), is opened (Fig. 4).
- the required vacuum can then be added to the suction valve Queue to open so that wastewater can be extracted.
- valve piston (82) of the switching valve (72), via which the ventilation valve is controlled is longer than the valve piston (80) of the switching valve (70), the switching valve remains (72) initially closed even when the switching valve (70) is open. It will only wastewater conveyed.
- valve pistons (80) and (82) of the switching valves (70) and (72) Due to the dimensions of the valve pistons (80) and (82) of the switching valves (70) and (72), these can be opened at the same time, so that there may be an overlap of wastewater and air production. By changing the length the valve piston (80) and (82) can, however, also follow one another in time can be achieved.
- the disc-shaped element (84) skips the Switching valve (70) then the driver (64) when at in its lower end position located switching valve (70) of the main piston (22) in the direction of its first End position is shifted.
- the switching valve (70) is closed, so that the Chamber (62) and the slot in the valve piston (80) pressure equalization can take place via the connection (76) to the suction valve, so that this is closed.
- the closure valve (42) Shortly before the main piston (22) is in its first (lower in the drawing) end position is located, the closure valve (42) is torn from the opening (37) and can, due to gravity, into a cylindrical valve piston (44) The opening (96) of the section (26) of the main piston (22) falls back (FIG. 8).
- main piston (22) has two switching valves (70), (72) assigned, there is of course the possibility of a switching valve or more than to actuate two switching valves via the main piston (22). Can also be present several switching valves each control one suction valve.
- FIG. 9 is a variant of the control arrangement shown in FIGS. 1 to 8 to the extent that not on the main piston (22) or its section (46), but on the valve piston (44) of the closure valve (42) a limiter acts. This is intended to provide a clear open / close position of the closure valve (42) be assured.
- the valve piston (44) has two mutually spaced grooves (60) into which Snap the ball elements (54) into place when the shut-off valve (42) is open or closed position.
- About the ball elements (54) act on the Valve piston (44) radial forces which are caused by the fact that the ball elements (54) are circumferentially surrounded by a clamping ring (98).
- a clamping ring (98) To slip the ball elements (54) and the clamping ring (58) are excluded, these are in a circumferential recess of the intermediate wall (34) or one of these outgoing section arranged, in turn, the valve seat for the valve plate (40) of the closure valve (42).
- the design of the limiter (54) shown in FIG. 9 is a clear one Opening or closing the chamber (28) and thus its timer function ensured.
