Definitions

  • the invention relates to a housing with therein Line adapters having connection adapters for a system one or more centrifugal pumps with components such as one or more Multi-way valves and / or manifolds via compatible System connections are hydraulically interconnected, the Openings of the compatible system connections lie in levels that parallel to the level of rotation of an impeller of a centrifugal pump.
  • connection adapters with which the centrifugal pumps Type described above for example attached to boilers will. It is also possible between the pump and the boiler another distributor or valve to arrange. Systems in which individual components are "in-line" have to be hydraulically coupled Disadvantage that they are not in conventional heating circuits can be integrated at any point. For such a connection hydraulic distribution stations are known at which a pump of the type mentioned is mountable. This However, distribution stations are made up of a large number of individual ones Components assembled and thus difficult to handle and expensive to manufacture.
  • the object of the present invention is therefore a Connection adapter for a modular hydraulic system To create components that are simple in structure and simple Handling is inexpensive to manufacture and a variety of Offers possible uses.
  • connection adapter according to claim 1 solved.
  • connection adapter particularly advantageous on the connection adapter according to the invention is that it enables centrifugal pumps in the simplest way with front connections, as part of a modular system in particular horizontally arranged hydraulic components, in a conventional heating circuit with vertical or to integrate horizontal pipes.
  • the Centrifugal pump depending on the design of the system connections of the An additional valve, e.g. a Multi-way valve, or a distributor piece upstream. Because the connection adapter all functions in one United component, its handling is particularly comfortable and simple.
  • the connection adapter according to the invention offers a cost-effective solution for convenient connection hydraulic components to a heating system.
  • metal or plastic e.g. made of polyamide
  • the Connection adapter particularly inexpensive to manufacture. Also with this manufacturing technology, the leadership of Design line ducts as desired, so that through the Connection adapters offered a variety of possible uses are.
  • connection adapter three connecting pieces on and is thus for connecting one Pump with upstream three-way valve, upstream Double pump or three-way straightening device suitable.
  • connection adapter three connecting pieces on and is thus for connecting one Pump with upstream three-way valve, upstream Double pump or three-way straightening device suitable.
  • two connecting pieces each the two single or the two outlets form axially parallel so that their Openings are on a first level.
  • the opening of the remaining third connecting piece, which corresponds to the The outlet or inlet is on a second level, the is parallel to the first level. If in a beneficial Embodiment of the third connecting piece in the same axis how one of the other two connecting pieces lies, can be the connection adapter in a simple manner in a pipeline install an existing heating system.
  • connection adapter has four Connection spigot on and is thus for the connection of a pump with upstream four-way valve or for connecting one Double pump or three-way straightening device suitable.
  • this Embodiment are two connecting pieces axially parallel with their openings in a common plane, the two levels are parallel. For easy integration into a pipe system, it is particularly advantageous if each one of the connecting pieces in the first level in the axial Extension of the connecting piece of the second level.
  • connection adapter for a three- or four-way valve
  • connection adapter is particularly advantageous in one Use heating system in which the heating water and Hot water preparation from a common pump unit be supplied.
  • the connecting pieces are of the connection adapter by arranged in the housing Shutoff valves can be closed. So that the hydraulic System of the pump completely separated from the heating circuit be, so that a comfortable exchange of components and there is a favorable possibility of maintenance. To the nevertheless It is to ensure current through the connection adapter advantageous, the conduit through a valve connectable bypass line to connect.
  • the valves can be manually or electrically switchable.
  • connection adapter Overflow valves integrated. This is a safety function realized that an outflow of pump medium at dangerous Overpressure guaranteed. It is also possible to use the switchable Valves through overflow valves in the form of check valves to replace. To compensate for unwanted pressure peaks in the System can also be a pressure transducer such as a flexible membrane can be integrated into the connection adapter.
  • connection adapter has easy access to the hydraulic System offers it is beneficial in at least one of its Line channels a device for filtering the pump medium to provide. This filter keeps pump medium clean and gentle thus all components of the system. Because of the simple Accessibility is easy to clean. From the same It is therefore advantageous to use sensors in the connection adapter Measurement of system parameters such as heat quantity, volume flow, Install system pressure and / or temperature. The measured Values can be sent to external ones via electrical cables Display devices transferred or on displays on the housing or attached to the pump. In this particular Embodiment, the connection adapter plays a central role in any heating system.
  • connection adapter according to the invention are shown in the drawings and are described below described in more detail.
  • a connector adapter 1 with a housing 2 is made Plastic shown.
  • the cable ducts in the housing are not shown.
  • the connection adapter 1 with its end face 3 ( Figure 2), the compatible System connections, on a three-way valve 4 appropriate.
  • the three-way valve 4 points in this Embodiment a distribution box 5 and a switching unit 6 on.
  • the three-way valve 4 is in turn with one conventional centrifugal pump 7 with hydraulic unit 8 and electric motor 9 hydraulically connected.
  • the system connections whose openings are in planes that are parallel to the plane of rotation of the impeller arranged in the hydraulic unit 8 are compatible.
  • connection adapter 1 Connection piece 10, 11 and 12, the openings of which in levels are perpendicular to the system connections.
  • the openings of the connecting piece 10 and 11 lie in a first plane which is at a distance D from Level of the axially parallel connection piece 12 has.
  • the distance D in this particular case is 180 mm.
  • FIG. 2 shows an embodiment of a connection adapter 1 shown in Figure 1, in which the connecting piece 10 on the Axis of the connector 12 is while the connector 11 is laterally spaced by the distance E.
