Definitions

  • the invention relates to an intermediate piece which is provided for installation between a rotary flange installed in a water pipe and a device connected to the rotary flange, with cutouts for connecting to the water inlet and to the water outlet of the water pipe and for installing a backflow preventer and a pressure reducer.
  • a known intermediate piece of the aforementioned type can be directly installed in a straight water pipe, in which a part corresponding to the removal of the connection points of the intermediate piece is missing.
  • a pressure reducing valve and a filter are attached to the adapter on one side perpendicular to the axis of the water pipe.
  • a second pressure reducing valve which can also serve as a backflow preventer, is installed coaxially to the water pipe in the area of the water drain and then obviously removed.
  • the known intermediate piece has a complicated design and is difficult to manufacture. Although the cutouts for the passage of water are connected to one another, these cutouts form difficult-to-access chambers which, in the case of production by casting, can only be produced by means of lost cores (FR-A 2 285 499).
  • the invention has for its object to provide a simply designed and easy to manufacture intermediate piece that can be connected to a rotary flange connection also referred to as IQE connector.
  • This object is achieved in that the cutouts pass through the intermediate piece in a straight direction, connectable to the water inlet and the inlet for the device and receiving the backflow preventer, on the side of the water inlet and outlet a part of the center hole immediately surrounding and with the Connectable water drain first annulus and on the side of the device another part of the center hole immediately surrounding and connectable to the return of the device second annulus and that the two annuli are connected to each other via the pressure reducer arranged essentially outside of the annular spaces.
  • the special design and arrangement of the recesses allows the connection of the intermediate piece according to the invention to a rotary flange. Because of the easy accessibility of the center bore and the annular spaces of the intermediate piece in the axial direction of the center bore and at an angle to the axis of the center bore, simple manufacture is possible since there are no undercuts. If no device is to be connected to the adapter, its output side can be closed briefly.
  • a rotary flange is to be understood here as a fitting installed in the water pipe, which has arcuate cutouts which open into a flange arranged laterally to the water pipe, the connection surface of which extends parallel to the water pipe.
  • This flange can be "rotated” around the axis of the water pipe during installation and can thus be brought into any angular position with respect to the water pipe.
  • it allows devices to be flanged to the side, so that the actual strand of the water pipe does not have to be disconnected when such a device is replaced.
  • Such rotary flanges are also referred to as IQE connectors.
  • an intermediate piece 2 is flanged to an IQE connector 1, which is connected between a water meter (not shown) and the line leading to the consumer.
  • the connector 1 therefore has a water inlet 3 and a water outlet 4, the water flow moves in the direction of the arrows 53, 54.
  • the elbow leading the water inlet opens into a straight bore 5, which passes through the intermediate piece 2 transversely and forwards the water inlet at the end of the bore 5 into a corresponding inlet of a device, for example a filter.
  • a backflow preventer 52 is inserted, which has an outer tube section 6, which is supported at its inner end on an annular shoulder 7 of the wall 8 surrounding the bore 5.
  • the inner end section of the pipe section 6 tapers to a valve seat 9, after which it is flanged at its end in order to achieve a good contact with the annular shoulder 7.
  • a valve plate 10 cooperates, which is fastened to the inner end of a valve rod 11 and on which one end of a compression coil spring 12 is supported, the other end of which is supported in a block 13 which is fastened to the tube section 6 and projects inwards is and also has a guide for the valve rod 11.
  • the outer end section of the pipe section 6 of the backflow preventer has on its outside an annular shoulder 14 with which the pipe section 6 is additionally supported on a corresponding additional inner shoulder of the wall 8 of the bore 5.
  • the pipe section 6 is inserted from the device side into the bore 5 until the front end of the pipe section 6 bears against the shoulder 7 and its shoulder 14 against the corresponding shoulder of the wall 8.
  • the backflow preventer can therefore, for example for cleaning, easily pulled out of the bore 5 and can also be easily inserted into the bore 5. If the backflow preventer 52 is missing in the line 5, the water flows unhindered through the straight bore 5 to the input of the device connected to the intermediate piece 2.
  • the space 19 is open at its upper end in FIG. 1.
  • This opening 22 extends with the exception of the wall thickness of the housing 35 of the intermediate piece 2 over the entire cross section of this intermediate piece with the exception of the flanges provided at this point, not shown in FIG. 1, with which a pressure reducer 23 is attached to the upper end 21 of the housing is.
  • the pressure reducer 23 has a spring housing 24, on the upper inner end face of which a compression spring 26 is supported by an adjusting device 25 (not shown in more detail). The tension of the spring 26 can be adjusted by turning a knurled nut 27 arranged on the spring housing.
  • the lower end of the spring 26 is supported on a plate 28 which is fastened on a membrane 29 which is arranged via a seal 30 at the lower end of the spring housing 24.
  • the edges of the membrane 29 rest on an inner shoulder 31 of the upper end section 21 of the housing 35 of the intermediate piece 2.
  • the membrane can be fastened to the lower end of the spring housing 24, but it can also be placed loosely on the inner shoulder 31 and held by the lower end face of the spring housing 24 when the spring housing 24 is fastened to the housing section 21.
  • a central part 32 is fastened to the underside of the membrane 29 and has an outer annular shoulder 33, with which it rests on an inner shoulder 34 of the section of the housing 35 of the intermediate piece 2 surrounding the space 19 and there through the edges of the membrane 29 or the spring housing 24 is held.
  • the central part 32 has a central bore 36 in which a piston 37 is guided, the upper end of which is fixedly connected to the membrane 29 and which is sealed against the inner wall of the bore 36 by a lip seal 38.
  • a valve rod 39 is attached, at the lower end of which a valve plate 40 is arranged.
  • the central part 32 has the recesses 19 connecting the space 19 with the interior 55 of the bore 36, which are delimited by downwardly projecting lamellar webs 41 of the central part 32, which have a ring 42 at their lower end, the outer surface of which is connected by a seal 43 bears against the inner wall of the bore 20 and the inner surface of which forms a valve seat for the valve plate 40.
  • the valve plate 40, the valve days 39 and the piston 37 are provided with an axial pressure compensation bore 51, into which a radial bore -44 provided at the upper end of the piston 37 opens, one at the top of the membrane 29, laterally and below from the central part 32 enclosed space 45 connects to the annular space 15.
  • the space 45 is closed off by the lip seal 38 against the interior of the bore 36.
  • the spring housing 24 can be rigidly connected to the central part 32 over the edges of the membrane 29 and the seal 30, but this connection can also be releasable.
  • FIG. 1 shows that no part of the pressure reducer 23 is engaged behind by housing parts of the intermediate piece 2 in such a way that removal of the pressure reducer is prevented after loosening a flange connection shown in FIG. 2.
  • FIG. 2 shows a filter 46 connected to the intermediate piece 2 in a top view from above.
  • pressure gauges 47 and 48 are also shown, one of which is connected to the annular space 17 and the other to the annular space 15 of the intermediate piece 2.
