Definitions

  • the invention relates to a valve arrangement for a pipe separator for separating a from a drinking water system refillable or refillable domestic water system from this Drinking water system, with one upstream and one downstream Backflow preventer, both in the direction from the domestic water system to the Close the drinking water system, and a relief valve that depends on the pressure of the Drinking water system is acted upon in the closing direction and through which the space between the backflow preventer can be connected to a drain when this pressure is removed.
  • the domestic water system can be a heating system, for example.
  • Such one Heating system is filled from a drinking water system, the drinking water pipe, or refilled. It must be prevented under all circumstances that one Pressure drop in the drinking water system Water from the domestic water system into the Drinking water system flows back.
  • "non-return valves" intended. These are spring-loaded check valves that are under the influence of the Drinking water pressure only in the direction from the drinking water system to the domestic water system open up. However, this is also not considered sufficient for continuous operation. Rather, after the filling or refilling process is complete, there is a physical separation between drinking water system and process water system, for example by filling or refilling via a hose which after the completion of the filling or Refilling process is removed. This ensures that even leaks Shut-off valves or backflow preventer no hot water in the drinking water system can reach.
  • Drinking water flows over the of the backflow preventer pressed into the drinking water system. But if the drinking water pressure drops below a predetermined level, be it because of a Shut-off valve shuts off the drinking water system, be it because the drinking water pressure is off breaks down for any reason, the relief valve opens. Even if then a leaked backflow preventer service water from the service water system flows back, this backflowing used water flows over the drain and can open never get into the drinking water system.
  • a filling group which is connected to the domestic water system, e.g. one closed Heating system, is permanently installed and has a connection for a hose. about the hose to be connected in this way becomes the filling group with a drinking water system connected.
  • the filling group contains a shut-off valve and a pressure reducer.
  • the invention has for its object the filling process with a To simplify and facilitate pipe separator arrangement of the type mentioned.
  • this object is achieved in that one with an inlet connection and an outlet connection between a drinking water system and a Service water system installable, the backflow preventer and the relief valve containing pipe separator housing upstream of the upstream Backflow preventer in the flow path integrates a shut-off valve and one Has pressure reducer.
  • Such a pipe separator arrangement is fixed between the drinking water system and Domestic water system, e.g. a hot water central heating system installed. To the No hose connection needs to be made to fill or refill. The makes handling easier. By automatically opening the relief valve at There is no pressure difference between the drinking water system and the domestic water system in this case a mechanical separation of the systems is guaranteed.
  • a built-in pressure reducer ensures that the pressure in the domestic water system cannot exceed a predetermined value. If the pressure in the The domestic water system reaches the pressure set on the pressure reducer, this closes Valve of the pressure reducer and thus interrupts the filling process, even if the pressure should be higher in the drinking water system.
  • the pressure reducer offers an additional one Security against the backflow of process water into the drinking water system. By the Shut-off valve can interrupt the filling process and the drinking water system in the Normal operation can be safely separated from the hot water system, independently e.g. from the backflow preventer.
  • the whole pipe separator arrangement is compact and easy to install assembly.
  • the backflow preventer and the Relief valve combined into one assembly which can be pulled out as a whole into the Drinking and process water connections and the pipe separator housing with drain can be used.
  • the relief valve forms a valve spool on a Face of the drinking water pressure and on the opposite face of the pressure in a space between the non-return valves is applied and by a side connected to the drain in the closed position Drain opening of the pipe separator housing can be covered.
  • the pipe separator housing has an inlet connection on an inlet side and one thus aligned outlet connection on the opposite outlet side, the one define common axis.
  • the location hole is open the inlet side is open and can be closed by a stopper.
  • the assembly with Backflow preventer and relief valve is inserted in the location hole. On Drain connection branches from the location hole.
  • the shut-off valve and the Pressure reducers are in the flow path upstream from the upstream Backflow preventer arranged.
  • the shut-off valve is in an inlet channel immediately behind the Inlet port seated on the common axis of the inlet and outlet port Ball valve.
  • a nozzle is formed, which is a cylindrical Recording forms.
  • a first section of the connecting channel opens out from the inlet channel behind the ball valve in the upper part of the jacket surface.
  • a second section of the connecting channel extends from the lower part of the lateral surface of the Recording from and opens into the receiving bore upstream of the upstream backflow preventer.
  • a trained as a closed assembly Pressure reducer is inserted in the socket.
  • the two sections of the Connection channel run essentially parallel to each other and under one Angle to the common axis of the inlet and outlet connection.
  • Test connections for the are advantageously on the pipe separator housing Inlet pressure, outlet pressure and medium pressure between the Backflow preventers provided.
  • 10 denotes a pipe separator housing.
  • the pipe separator housing 10 has an inlet port 12 on an inlet side and an outlet port 14 on one Outlet side on. Inlet port 12 and outlet port 14 are coaxial with one common axis 16 on opposite sides of the pipe separator housing 10 arranged.
  • a receiving bore 18 is provided in the pipe separator housing 10. The axis of the receiving bore 18 forms with the axis 16 of the inlet port 12 and Outlet port 14 an acute angle.
  • the receiving bore 18 is on the Outlet side directly in connection with an outlet channel 20 of the outlet connection. On the inlet side, the receiving bore 18 is open and through a plug 22nd lockable.
  • the backflow preventer 26 and 28 and the Relief valve 30 are combined into one assembly, which can be pulled out as a whole the receiving hole 18 can be used.
  • the relief valve 30 forms one Valve spool, which on a face of the drinking water pressure and on the opposite face from the pressure in a space between the Backflow preventer 26 and 28 is applied.
  • Drain 32 From the receiving bore 18 goes Drain 32 from.
  • the axis of the process runs through axis 16 and the axis the receiving bore 18 certain plane and perpendicular to the axis 16. By the Valve slide is in the closed position a side connected to the outlet 32 Drain opening of the pipe separator housing 10 can be covered.
  • the inlet-side end of the receiving bore 18 is via a connecting channel is generally designated 34, with an inlet channel 36 of the inlet port 12 connected.
