  • a control arrangement for a vacuum actuated suction intended for a vacuum sewer system
  • a housing having an outer wall, arranged therein by a wastewater caused by accumulated back pressure from a first switchable to a second position first valve, a via the first valve pressure-adjustable limited by a first membrane first chamber, wherein the first membrane is operatively connected to a second valve, passes through the depending on its position negative pressure or atmospheric pressure to the suction valve, a first connection via which the first chamber a negative pressure source is connected, which is shut off in the absence of or too little dynamic pressure of the first in its first position
  • the first diaphragm is switchable together with the second valve of a first suction valve connected to the atmospheric pressure position into a second suction valve connecting the vacuum position, wherein the
  • a corresponding vacuum sewerage system comprises as essential components house connection shafts with a normally open control arrangement and shut-off or suction valves, a subsequent line system with systematically arranged high and low points and a vacuum station with sewage collection tanks, sewage pumps, vacuum pumps, measuring and control technology ,
  • a swamp of a z. B. located on a property boundary shaft, in which the exclusively pneumatically controlled shut-off valves and the associated control arrangement are housed.
  • an air-enclosing pitot tube Connected to the sump is an air-enclosing pitot tube, wherein the trapped air is hydrostatically compressed by liquid accumulated in the sump, so that a back pressure is generated.
  • the shut-off valve is opened and the waste water is sucked into the vacuum line in the presence of a defined dynamic pressure.
  • the valve closes depending on the time after a few seconds via spring force and vacuum.
  • the wastewater itself collects at the low points in the pipe system and is pushed by nachschmanender air gradually over the following high points in the direction of the vacuum station. From the collecting tank of the vacuum station then the wastewater with conventional sewage pumps via a pressure and Freigementechnisch to Wastewater treatment plant promoted. In the collecting tank and in the piping system, a vacuum generator such as a vacuum pump maintains a negative pressure.
  • the control arrangement associated with the shut-off valve should thereby enable automatic adaptation to the wastewater portions to be suctioned off and to the operating conditions (for example the strength of the existing negative pressure) in the discharge system.
  • a control arrangement according to the DE-C-43 36 020 is extremely compact and structurally simple and offers a high level of operational safety.
  • the control assembly closes the vacuum supply to the shut-off valve after a defined period of time and the shut-off valve vented with ambient air, so that the shut-off valve is closed.
  • the time remaining after the suction before the closing of the suction valve is used for admitting transport air from the environment in the vacuum system. For the system function, it would be desirable if the volume ratio of the admitted air and the sucked liquid would be higher, the weaker the upcoming negative pressure is.
  • control device is also characterized in particular by the fact that it keeps the after-opening time for the air approximately constant and the volume of the extracted wastewater portion is smaller, the weaker the upcoming negative pressure is. Another advantage of this control device is to cause a sudden change in the state of the control in that the second valve controlling the connection to the shut-off valve is switched abruptly.
  • the suction time is dependent on the existing vacuum in an unfavorable for the entire system way, since the opening times are in turn dependent on the prevailing negative pressure.
  • the opening time is shorter at low negative pressure than at high negative pressure.
  • a further disadvantage is that opening of the negative pressure to the shut-off valve releasing second valve can be done even at low vacuum, but not always sufficient for rapid suction. As a result, the risk arises that wastewater is raised in the freezing area of the line and can freeze there.
  • a control arrangement of the type mentioned is the EP-A-1 091 053 which is simple in construction and ensures that liquid can not penetrate into the pressurizable by vacuum chamber.
  • the present invention is based on the object, a control arrangement of the type mentioned in such a way that when compared to the known control arrangements further simplified construction high reliability is given. At the same time it should be ensured that liquid can not penetrate or accumulate in the control arrangement, which impairs the functionality. According to another aspect, the possibility should be given to be able to change a switching of the control valve and thus the suction valve in a simple manner, so that switching can be done at desired dynamic pressures. Also, if necessary, a manual switching of the control arrangement for actuating the suction valve to be made possible.

Dispositif de commande pour une vanne d'aspiration actionnable par dépression, destiné à un système à dépression pour eaux usées, comprenant une première soupape (32) ainsi qu'une seconds soupape (34) reliée à la première de manière fonctionnelle, selon la position de laquelle est actionnable la vanne d'aspiration au moyen de laquelle les eaux usées accumulées peuvent être aspirées par le système pour eaux usées,
    caractérisé en ce
    que sur la première soupape (32) s'exerce une pression dynamique générée par l'accumulation des eaux usées, laquelle pression alimente un espace intermédiaire (52) entre une membrane de déclenchement (36) et une membrane réagissant à la pression dynamique (38) qui forment ensemble une unité et la première soupape.
