Definitions

  • the invention relates to an adapter for installation between a rotary flange installed in a water pipe and a device connected to the rotary flange, for. B. a filter, a metering device or the like ..
  • a backflow preventer In domestic water pipes, a backflow preventer should be installed behind the water meter. A filter is often already installed behind the backflow preventer. If necessary, for example at a higher water inlet pressure than 6 bar, a pressure reducer is provided at this point.
  • all three fittings that is, check valves, pressure reducers and filters are combined into a single unit. This unit is relatively large and cumbersome to use, and its use is uneconomical if one of these fittings is already installed. If you do not want to connect two identical fittings in series, you have to remove the existing fitting, which means that it is not possible to remove individual fittings, such as filters or non-return valves, from the known domestic water stations. These domestic water stations are therefore not suitable for retrofitting existing house connections, especially if a filter is already installed.
  • the invention has for its object to develop a valve that is suitable for retrofitting existing house water connections.
  • This object is achieved according to the invention with an intermediate piece, which has the water inlet and water outlet openings of the rotary flange and the device connecting recesses and in which a non-return valve and a pressure reducer are installed in these recesses.
  • This adapter can therefore be used both in connection with an existing filter and, if no filter is required, in water pipes without a filter.
  • a part can be provided with which the connections for the device, that is to say the output side of the intermediate piece, are short-circuited.
  • a rotating flange is to be understood here as a fitting built into the water pipe, the arched recesses has, which open into a laterally arranged to the water pipe flange, the connection surface 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.
  • the backflow preventer can be permanently installed in the intermediate piece. In one embodiment, however, this backflow preventer is detachably fastened in the intermediate piece, for example in a straight section accessible from the outside of a bore leading the inlet to the filter.
  • the detachable fastening is particularly advantageous when assembling the intermediate piece and also for repairs.
  • This backflow preventer is expediently located in a section of the bore or other recess accessible from the device side.
  • the releasable attachment can be realized in such a way that the backflow preventer is only inserted into the bore and is held between a stop on the appliance flange and a shoulder in the bore when the device, for example a filter, is flanged on.
  • the backflow preventer can have a tube section forming its outer wall, which contains a valve seat and a valve plate and one end of which is supported on this Closing spring and an abutment for this spring includes.
  • the backflow preventer is therefore fully installed in this pipe section and can be inserted as a whole in bores or other recesses that guide the water flow.
  • the pressure reducer can be firmly connected to the intermediate piece.
  • the pressure reducer as a whole can be removed from the intermediate piece, and the opening in which the pressure reducer is fastened can be closed by a cover when the pressure reducer is removed. This has the advantage that the adapter is available for installation with or without a pressure reducer. In the event of a subsequent change in pressure in the water supply, a pressure reducer can either be installed or removed without the intermediate piece having to be removed.
  • the spring housing of the pressure reducer which contains a spring acting on the diaphragm and an adjusting device for the spring tension, projects outward from the housing of the intermediate piece, whereas the valve rod connected to the diaphragm, the valve cone and the valve seat are located inside the Intermediate piece.
  • These parts are shaped so that they can be pulled out of the housing of the intermediate piece together with the spring housing, so they have no parts that are engaged by adjacent parts of the housing of the intermediate piece.
  • the spring housing is connected to a central part, which has a central bore and contains at its end facing away from the membrane a valve seat, the central bore surrounding the valve rod at a distance.
  • the inner wall of the bore therefore forms a guide for the water flow, the amount of which is regulated by the flow cross section between the valve cone and the valve seat.
  • the central part has openings which extend radially to the valve rod and which are connected to a water-carrying recess in the intermediate piece. This central part also has a guide for the valve rod.
  • the bore of the central part can run in embodiments of the invention approximately in the longitudinal axis of the intermediate piece, so that there is a relatively simple construction of the intermediate piece.
  • This embodiment of the invention can be further developed in such a way that the cutouts of the intermediate piece for the water inflow and the cutout for the water routing with respect to the valve rod are arranged diametrically opposite one another, which in turn enables a simple construction of the intermediate piece, so that the pressure reducer is removed or installed can be removed without having to remove a device connected to the device side of the intermediate piece or the intermediate piece from the connecting piece JQE.
  • an intermediate piece 2 is flanged to a JQE 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 to ensure good contact with the annular shoulder 7 to achieve.
  • 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 into the bore 5 from the device side until the front end of the pipe section 6 abuts the shoulder 7 and its shoulder 14 abuts the corresponding shoulder of the wall 8.
  • the backflow preventer can therefore be easily pulled out of the bore 5, for example for cleaning, and can also be easily inserted into the bore 5 again. 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 bore 5 is surrounded on the side facing the connector 1 by an annular space 15 which opens into a corresponding annular space 16 of the connector 1.
  • the bore 5 is surrounded by an annular space 17, which opens into a corresponding annular space of a connected device, from which the water flowing out of the device is fed to the annular space 17.
  • the annular space 17 is connected via a channel 18 to a space 19 in the upper part of the intermediate piece 2 in FIG. 1, which in turn is connected to the annular space 15 via a bore 20, via which the water is discharged to the consumer.
  • 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 fixed to the membrane 29 is connected and which is sealed by a lip seal 38 against the inner wall of the bore 36.
  • 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 from 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.
  • the pressure reducer can also be fastened in the housing 35 of the intermediate piece 2 in another way, for example by means of a thread or the like.
  • 2 shows the top view of a flange 49 (not shown in FIG. 1) arranged on the spring housing 24, and an underlying flange connected by screws 50 is located on the housing 35.
  • 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.
