Definitions

  • the invention relates to a valve assembly for a pipe separator for separating a replenishable from a drinking water system or domestic hot water system of this drinking water system, with an upstream and downstream backflow preventer, both close in the direction of the service water system to the drinking water system, and a relief valve, of the Pressure of the drinking water system is acted upon in the closing direction and over which the space between the backflow preventer is connected with elimination of this pressure with a drain.
  • the service water system may be, for example, a heating system.
  • a heating system is from a drinking water system, the drinking water pipe, filled or refilled. It must be prevented under all circumstances that, for example, at a pressure drop in the drinking water system, water from the service water system flows back into the drinking water system.
  • backflow preventer are provided. These are spring-loaded check valves, which open under the influence of drinking water pressure only in the direction of the drinking water system to the process water system. However, this is not considered sufficient for continuous operation. Rather, after completion of the filling or refilling a physical separation between drinking water system and service water system is prescribed, for example by filling or refilling via a hose which is removed after completion of the filling or refilling process. This ensures that even over leaky shut-off valves or backflow preventer no hot water can get into the drinking water system.
  • the company publication "SYR Filling Group Type 2128" by Hans Sasserath & Co. KG discloses a filling group which is attached to the process water system, e.g. a closed heating system, is permanently installed and has a connection for a hose.
  • the filling group is connected to a drinking water system via the hose to be connected.
  • the filling group contains a shut-off valve and a pressure reducer.
  • the invention has for its object to simplify the filling process with a pipe separator arrangement of the type mentioned and facilitate.
  • Such a pipe separator arrangement is fixed between drinking water system and service water system, e.g. a hot water central heating system, installed. To fill or refill no hose connection needs to be made. This facilitates handling. Due to the automatic opening of the relief valve when there is no pressure difference between the drinking water system and the service water system, a mechanical separation of the systems is ensured in this case.
  • a built-in pressure reducer ensures that the pressure in the service water system can not exceed a predetermined value. When the pressure in the service water system reaches the pressure set at the pressure reducer, the pressure reducer valve closes, interrupting the filling even if the pressure in the potable water system is higher.
  • the pressure reducer provides additional security against a backflow of service water into the drinking water system. Through the shut-off valve, the filling process can be interrupted and the drinking water system can be safely separated from the service water system in normal operation, independently e.g. from the backflow preventers.
  • the entire pipe separator assembly is a compact and easy to install assembly.
  • the backflow preventer and the relief valve are combined to form an assembly, which can be used as a whole in a pull-out in which the drinking and service water connections and the drainage having Rohrtrennergephaseuse.
  • the relief valve forms a valve spool, which is acted upon on an end face of the drinking water pressure and on the opposite end face of the pressure in a space between the backflow preventer and by the closed position in the closed position associated with the outlet side drain opening of the Rohrtrennergephaseuses.
  • the Rohrtrennergeophuse has an inlet port on an inlet side and an aligned outlet port on the opposite outlet side, the one define common axis.
  • a receiving bore is formed, whose axis forms an angle with the common axis of the inlet and outlet port and on the outlet side is directly on the outlet side in communication and on the other hand connected on the inlet side via a connecting channel with the inlet port.
  • the receiving bore is open on the inlet side and closed by a plug.
  • the assembly with backflow preventer and relief valve is inserted into the receiving bore.
  • a drain connection branches off from the receiving bore.
  • the check valve and the pressure reducer are arranged in the flow path upstream of the upstream backflow preventer.
  • the shut-off valve is a ball valve seated in an inlet passage immediately behind the inlet port on the common axis of the inlet and outlet ports.
  • a nozzle is formed, which forms a cylindrical receptacle.
  • a first portion of the connecting channel opens, starting from the inlet channel behind the ball valve in the upper part of the lateral surface of the receptacle.
  • a second portion of the connecting channel extends from the lower part of the lateral surface of the receptacle and opens into the receiving bore upstream of the upstream backflow preventer.
  • a trained as a closed module pressure reducer is inserted into the receptacle of the nozzle.
  • the two portions of the connecting channel are substantially parallel to each other and at an angle to the common axis of the inlet and outlet ports.
  • test connections for the inlet pressure, the outlet pressure and the mean pressure between the backflow preventer are provided on the pipe separator housing.
  • Fig.1 is denoted by 10 a Rohrtrennergephaseuse.
  • the pipe separator housing 10 has an inlet port 12 on an inlet side and an outlet port 14 on an outlet side. Inlet port 12 and outlet port 14 are coaxially disposed with a common axis 16 on opposite sides of the pipe separator housing 10.
  • 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 at an acute angle.
  • the receiving bore 18 is on the outlet side directly with an outlet channel 20 of the outlet port in combination. On the inlet side, the receiving bore 18 is open and lockable by a plug 22.
  • a Rohrtrennerpatrone 24 with an upstream mulch disciplineverhinderer 26, a downstream mulch redesignverhinderer 28 and an interposed in the water flow therebetodean, designed as a slide valve relief valve 30.
  • the backflow preventer 26 and 28 and the relief valve 30 are combined into an assembly, as a whole pulled out into the receiving bore 18 can be used.
  • the relief valve 30 forms a valve spool, which is acted upon on an end face of the drinking water pressure and on the opposite end face of the pressure in a space between the backflow preventers 26 and 28. From the receiving bore 18 is a drain 32.
  • the inlet end of the receiving bore 18 is connected via a connecting channel, which is generally designated 34, with an inlet channel 36 of the inlet port 12.
  • a connecting channel which is generally designated 34
  • an inlet channel 36 of the inlet port 12 In the inlet channel 36 sits a ball valve designed as a check valve 38 with a lever 40th
  • the connecting channel 34 consists of two sections: A first portion 46 extends from the inlet channel 36 downstream of the shut-off valve 38 to the receptacle 44 and opens in the upper part of the lateral surface of the receptacle 44. A second portion 48 of the connecting channel 34 extends from the lower part of the lateral surface the receptacle 44 and opens into the receiving bore 18 upstream of the upstream scaffold formulaverhinderer 26.
  • pressure reducer 50 is sealingly inserted in the receptacle 44 designed as a closed assembly. The valve passage of the pressure reducer 50 controls the connection between the sections 46 and 48 of the connection channel 34.
  • a transverse bore 52 connects the receptacle 44 downstream of the control valve of the pressure reducer 50 with test ports 54A and 54B for connecting a pressure gauge either on one side or the other depending on the installation of the filling valve.
  • the test ports are closed by plugs 56A and 56B, respectively. Through these test ports, the pressure upstream of the upstream backflow preventer 26 can be measured.
  • Another test port 58 departs from the receiving bore 18 between the upstream backflow preventer 26 and the downstream backflow preventer 28.
  • the test port 58 is closed by a plug 60. Through this test port 58, a pressure gauge can be connected, which allows to control the pressure between the upstream and downstream backflow preventer.
  • a test port 62 is provided, which goes off from the outlet passage 20. At this test port, a pressure gauge 64 is connected.
