Definitions

  • the invention relates to a check valve with a position indicating the position of the valve actuator displacement sensor whose movable part is connected to the valve actuator.
  • valve actuator is connected via a transmission rod with a displacement sensor to indicate the position of the valve actuator can.
  • a transmission rod with a displacement sensor to indicate the position of the valve actuator can.
  • the object of the invention is to improve a check valve of the type mentioned so that it has small external dimensions with a simple construction and is preferably used as a compact part in a line, without leading to the outside mechanical parts.
  • This object is achieved in that is arranged for continuous measurement, the movable part of the displacement sensor within the valve housing.
  • a valve is created that enables position feedback and volume flow sensing.
  • the solution according to the invention can be used particularly advantageously in heating circuits, in particular in a decentralized pump system.
  • By determining the volume flow it is possible to accurately detect the operating point of a pump. This size can be used as a controlled variable.
  • the structural design of the invention makes it possible to use the sensor element at the same time as a non-return valve and thus save space and costs compared to a separate component.
  • the sensor element can be integrated in a pump housing due to the possible small size.
  • the movable part of the displacement sensor connected to the valve actuator is a submersible or transverse armature whose movement can be detected by at least one coil.
  • the movable part of the displacement sensor connected to the valve actuator is a permanent magnet whose movement can be detected by at least one coil or a current-carrying conductor (Hall effect).
  • the coil (s) is arranged inside or outside the valve housing / are.
  • the movable part of the displacement sensor is fastened directly to the valve actuator, in particular on the valve disk, so that a particularly space-saving design is achieved.
  • a further advantageous embodiment is provided when the movable part of the displacement sensor is arranged in particular on a body, in particular pin or piston, which in particular protrudes coaxially within the housing on the valve actuator. Also is beneficial if that movable part of the displacement sensor is formed by a metal coating of the valve actuator and / or a valve actuator on the protruding body in particular pin or piston.
  • Fig. 5 is a valve actuator with outer metal flat ring.
  • the check valve has a cylindrical valve housing 1 made of plastic, which is fastened with sealing rings 2 within a tube 3 or a pump channel.
  • the valve housing has a coaxial inlet 4 on one side and a coaxial outlet 5 on the opposite side, so that the housing 1 according to the arrow F can be flowed through by a liquid.
  • the inlet 4 forms a valve seat 6 which can be closed by a plate-shaped valve actuator 7.
  • the valve actuator 7 is acted upon by a helical compression spring 8, which presses the valve actuator to the closed position.
  • a guide member 9 is coaxially mounted in the valve housing 1, which forms a coaxial sleeve 10, in which a piston-shaped pin 11 slidably rests and is guided, which at the back of the Valve actuator 7 fastened in particular is formed.

  • the outside of the valve housing 1 is provided with at least one coil 14 which surrounds the valve housing 1, as shown in FIG. 2.
  • a movement of the valve actuator 7 and thus of the part 13 leads to measurable current changes in the coil 14 and thus to register the position of the valve actuator 7. This allows a continuous measurement.
  • the metal part 13 may be arranged differently on or in the valve actuator 7.
