Definitions

  • connection adapter having a housing with line ducts therein for a system in which one or more centrifugal pumps with components such as one-way or multi-way valves and / or distributor pieces can be hydraulically connected by means of compatible system connections, the openings of the compatible system connections lying in levels that are parallel to the level of rotation of an impeller of a centrifugal pump.
  • Connection adapters are known with which centrifugal pumps of the type described above are attached, for example, to boilers. It is also possible to arrange a further distributor or a valve between the pump and the boiler.
  • Systems of this type in which individual components are hydraulically coupled "in-line" have the disadvantage that they cannot be integrated at any point in conventional heating circuits.
  • hydraulic distribution stations are known, on which a pump of the type mentioned can be mounted. However, these distribution stations are assembled from a large number of individual components and are therefore difficult to handle and expensive to manufacture.
  • the object of the present invention is therefore to provide a connection adapter for a to create a modular system of hydraulic components with a simple structure and simple handling is cheap to manufacture and a variety of Offers possible uses.
  • connection adapter according to claim 1.
  • Advantageous embodiments of the connection adapter according to the invention are listed in the subclaims.
  • a particular advantage of the connection adapter according to the invention is that it enables the simplest way to integrate centrifugal pumps with end connections, as part of a modular system, in particular horizontally arranged hydraulic components, into a conventional heating circuit with vertical or horizontal pipes.
  • the centrifugal pump can be preceded by an additional valve, eg a multi-way valve, or a distributor. Since the connection adapter combines all functions in a single component, its handling is particularly convenient and simple.
  • the connection adapter according to the invention offers an inexpensive solution for the convenient connection of hydraulic components to a heating system.
  • the housing of the connection adapter and the line ducts therein can be made in one piece from metal or plastic, for example from polyamide, in particular as an injection molded part.
  • metal or plastic for example from polyamide, in particular as an injection molded part.
  • connection adapter has three connection pieces and is therefore suitable for connecting a pump with an upstream three-way valve, an upstream double pump or a three-way straightening device.
  • the third connection piece is in the same axis as one of the other two connection pieces, the connection adapter can be easily installed in a pipe of an existing heating system.
  • connection adapter has four connecting pieces and is therefore suitable for connecting a pump with an upstream four-way valve or for connecting a double pump or three-way straightening device.
  • two connecting pieces each lie axially parallel with their openings in a common plane, the two planes being parallel.
  • one of the connecting pieces in the first level lies in the axial extension of the connecting piece on the second level.
  • the connection adapter can be used particularly advantageously in a heating system in which the heating water and the hot water preparation are supplied by a common pump unit.
  • the connecting pieces are advantageously provided with flanges or threads of the commonly used standard.
  • connection to a piping system particularly easy.
  • connection piece of the connection adapter can be closed by shut-off valves arranged in the housing.
  • shut-off valves arranged in the housing.
  • the valves can be switched manually or electrically.
  • overflow valves are integrated in the connection adapter. This implements a safety function that ensures that pumped medium flows out in the event of dangerous excess pressure. It is also possible to replace the switchable valves with overflow valves in the form of check valves.
  • a pressure sensor such as a flexible membrane can also be integrated in the connection adapter.
  • connection adapter Since the connection adapter provides easy access to the hydraulic system, it is advantageous to provide a device for filtering the pump medium in at least one of its line channels. This filter keeps the pump medium clean and therefore protects all components of the system. It is easy to clean because of its easy access. For the same reason, it is advantageous to install sensors for measuring system parameters such as the amount of heat, volume flow, system pressure and / or temperature in the connection adapter. The measured values can be transmitted to external display devices via electrical cables or shown on displays attached to the housing or the pump. In this particular embodiment, the connection adapter plays a central role in every heating system. Embodiments of the connection adapter according to the invention are shown in the drawings and are described in more detail below.
  • connection adapter 1 is shown with a housing 2 made of plastic.
  • the line ducts in the housing are not shown.
  • the connection adapter 1 is attached to a three-way valve 4 with its end face 3 (FIG. 2), which has compatible system connections.
  • the three-way valve 4 has a distribution box 5 and a switching unit 6.
  • the three-way valve 4 is in turn hydraulically connected to a conventional centrifugal pump 7 with a hydraulic unit 8 and an electric motor 9.
  • the system connections, the openings of which lie in planes which are parallel to the rotational plane of the impeller arranged in the hydraulic unit 8, are each compatible.
  • the system shown in Figure 1 can be installed in a heating system with vertical pipes (not shown).
  • connection adapter 1 has connection pieces 10, 11 and 12, the openings of which lie in planes perpendicular to the system connections.
  • the axially parallel connecting pieces 10 and 11 form inlets (arrows A and B) and the connecting piece 12 form an outlet (arrows C).
  • the openings of the connecting pieces 10 and 11 lie in a first plane which is at a distance D from the plane of the axially parallel connecting piece 12.
  • the distance D is 180 mm in this special case.
  • FIG. 2 shows an embodiment of a connection adapter 1 according to FIG. 1, in which the connection piece 10 lies on the axis of the connection piece 12, while the connection piece 11 is laterally spaced by the distance E.
