Definitions

  • the upstream fluid system may be a drinking water system.
  • the downstream fluid system may be, for example, a heating system. It must be absolutely prevented that contaminated water from the heating system when refilling or refilling the heating system flows back into the drinking water system, for example, the fact that the pressure in the drinking water system collapses for some reason. There are so-called.
  • Backflow preventer These are spring-loaded valves which allow fluid flow in only one direction, namely from the upstream to the downstream system. However, such backflow preventers can become leaky. Therefore, for example, is a drinking water and heating water Separation of the fluid systems alone by backflow preventer not allowed. There must be a physical separation of the fluid systems, so that in case of failure between the systems a connection to a drain and to the atmosphere is made.
  • System or pipe separators usually include an upstream backflow preventer connected to the upstream liquid system and a downstream backflow preventer connected to the downstream system. Between the backflow preventers is disposed a pressure controlled dump valve which establishes a passage from the upstream liquid system to the downstream liquid system when there is a sufficient pressure differential between the two liquid systems so that the liquid can safely flow only from the upstream to the downstream liquid system. If this pressure drop does not exist, the drain valve establishes a connection of the space between the backflow preventers with the atmosphere and a drain.
  • a system separator is for example in the DE 10 2005 031 422.8 or in the DE 10 2005 049 110.3 described.
  • the drain valve is a spring-loaded, displaceable in a Arniaturengephaseuse piston.
  • This piston has a central passage and at its downstream end face an annular valve seat, which comes to a valve-tight ring seal axially to the plant.
  • the passage then establishes an atmosphere-closed connection between the upstream and downstream fluid systems.
  • the upstream backflow preventer sits in the passageway.
  • the inlet pressure in the drinking water system initially forces the piston of the discharge valve against the action of the spring acting on it into its operating position in which it connects to the drinking water system Atmosphere and interrupts the process and establishes a connection between drinking water system and heating system. Then, the upstream and downstream backflow preventers are pressed. It streams drinking water to the heating system and fill it up or down. The heating system is then filled to an outlet pressure that is below the inlet pressure. In normal operation, the difference between inlet pressure and outlet pressure is determined by the pressure drop across the backflow preventers, that is, by the strength of the return valve springs.
  • the intermediate pressure is in accordance with the pressure drop across the upstream backflow preventer and the pressure drop across the upstream backflow preventer.
  • the pressure difference between the inlet pressure and the mean pressure must be greater than a limit determined by the loading spring of the valve body of the drain valve.
  • System separators must be of type "BA" depending on the area of application. This means that they must be provided with test connections, which allow a review of the pressure conditions. This is particularly the case when particularly contaminated water to be separated from the drinking water supply.
  • the filling of heating systems takes place with the correspondingly reduced by the system separator inlet pressure, which occurs when an upstream barrier is opened.
  • inlet pressure is typically in the range of 4 bar and corresponds to the pressure that is set behind the drinking water supply with about a pressure reducer for the building.
  • the system separator can be followed by a pressure reducer.
  • the downstream pressure reducer is then adjusted to a lower pressure.
  • Such a pressure reducer prevents in particular that water flows after when the desired heating pressure has set, that is, when the filling or Refilling process is completed.
  • the arrangement with a downstream pressure reducer is bulky, requires a particularly large number of components and is correspondingly expensive to produce. The installation is also expensive.
  • EP 1681520 A2 The applicant discloses an arrangement with a pressure reducer and a system separator arrangement.
  • the arrangement has a housing with a housing bore.
  • the housing bore has two openings.
  • An opening forms a housing socket, in which a pressure reducer is inserted.
  • the pressure reducer is not provided as a whole in the housing bore, but sits on the neck.
  • Another opening is provided at the opposite end of the housing bore. Through this opening, the components of the system separator are accessible.
  • the use of two openings requires that both housing ends be spaced from the pipeline. This makes the arrangement voluminous and heavy. It requires a lot of space for transport and storage.
  • the use of two openings in particular requires a high assembly cost. Two steps must be carried out: first, the pressure reducer becomes "from the left", and second, the backflow preventer and other components of the system separator are inserted "from the right". Also, two different drilling steps must be performed to make the housing bore.
  • EP 928023 A1 Applicant discloses a system separator with a pressure reducer.
  • the pressure reducer is located between the backflow preventer of the system separator.
  • the arrangement is very voluminous and complicated in manufacture and assembly. Each component practically has its own housing opening, through which it is accessible.
  • EP 1 452 652 A2 teaches that a system separator and a pressure reducer can be used in one arrangement.
  • the system separator sits in an elongated housing, which is arranged at an angle to the tube axis.
  • the pressure reducer is arranged perpendicular to the tube axis and is located outside the housing bore, in which the system separator is arranged.
  • the object is achieved in that the pressure reducer cartridge, the backflow preventer and the drain valve body are accessible through the same housing opening.
  • the system separator and the pressure reducer arrangement are arranged in the same housing bore.
  • the arrangement is particularly compact. It only needs a component to be installed. For the required maintenance, the housing opening is opened and the components of the system separator and the pressure reducer cartridge are easily accessible.
  • the system separator includes an upstream backflow preventer, a downstream backflow preventer, and a piston-formed, spring-loaded dump valve body fluidly disposed between the backflow preventers, the pressure reducer cartridge, the backflow preventer, and the dump valve body being coaxially disposed within the housing bore.

  • the valve plate is fixed.
  • the valve seat body is guided displaceably in this embodiment on a valve spindle connected to the valve spindle with an axial bore.
  • the outlet of the downstream non-return valve opens into the axial bore in the valve stem and the bore is connected to the space upstream of the valve seat.
  • the downstream backflow preventer is thus integrated directly into the pressure reducer cartridge.
  • the valve spindle is integrated into a cartridge case, which is insertable into the housing bore up to a stop, wherein the downstream backflow preventer can be inserted into the cartridge case.
  • the valve stem and the backflow preventer can therefore be pulled together with the cartridge case from the housing bore.
  • the valve spindle at the downstream end may comprise the valve plate, which projects into an interior of the cup-shaped valve seat body, wherein the valve spindle in the region of the interior of the valve seat body in the radial direction has a thickening which acts as a driver for the valve seat body when detaching the cartridge case from the housing bore , Then, the valve seat body is pulled out of the housing bore together with the cartridge case.
  • test ports are provided which allow a pressure measurement in the inlet, in the outlet and in the medium pressure space between the backflow preventer of the system separator.

  • a drain valve body 30 is provided on the inlet side.
  • the drain valve body is exposed to the spring force of a spring 32.
  • the spring 32 pushes the drain valve body with the associated components described below out of the housing bore. This makes it easily accessible.
