Definitions

  • the invention relates to a fitting, the housing of which is equipped with housing end faces for contacting pipelines and / or system components, an actuating means which is normally located on a pipeline axis is arranged in the housing, a closure element connected to the actuating means interacts with a seat arranged in the housing and the front faces of the housing wholly or partly part of the housing area enveloping a closure element and the housing end faces are designed as interfaces for connection to connection adapters, the spacing between the housing end faces determining the overall length of the fitting being made very small.
  • a two-part or multi-part welded socket is known, with the aid of which socket connections between components are possible which consist of differently weldable materials.
  • the welded socket With one end, the welded socket is mechanically clamped to the poorly weldable pipeline to be connected in a positive and non-positive manner and welded together in the longitudinal direction.
  • a weld seam arranged between the components made of different materials is relieved of the power transmission and only has a sealing function.
  • teeth, pins, polygonal surfaces or the like are provided between the components to be joined.
  • the other end of the welded socket is welded directly onto a pipe made of the same material as the welded socket.
  • DE-U 295 05 091 shows a fitting connection in the form of a thin-walled metallic pipe part, a so-called fitting, which forms a socket connection with an area that can be pressed from the outside.
  • the tubular molded part is pushed into a recess in the valve housing and, due to internal pressing, fits into a circumferential flat groove of the valve housing.
  • an O-ring is provided, with the help of which the sealing effect for the pressed-in pipe part is produced.
  • This type of connection is used for fittings in which the connections between the fittings and the pipes are made with the help of manually operated pressing tools. Due to the springback of the material that occurs during pressing, such a valve can only do a small amount. Transfer axial and torsional forces. Elastomer materials are usually used for the O-ring seals used, which is why the area of application is limited due to the lower temperature resistance.
  • a generic fitting is known from DE-A 19733544. This shows the connection of the valve body with various connection adapters, which enables connection to different piping systems. For this purpose, various connection adapters are shown, which rest on the front of the housing 15 sides of the valve body.
  • a fitting in which the housing is designed as a functional fitting unit in the form of a clamping fitting and that for another connection type, at least one connection adapter is permanently attached to at least one end face of the housing.
  • the actual function carrier of a fitting the housing with an actuating means arranged therein and acting on a closure piece and a closure piece connected to it, can be produced as a very small and short fitting unit in a functional design.
  • Such a valve body has no flanges and, depending on the guide variant can be easily clamped between pipe flanges designed according to different standards.
  • connection adapters From DE-U 298 07 955 and 299 20 410 fittings provided with connection adapters, a ball valve and a flap are known. However, these fittings absolutely require the prior installation of appropriate connection adapters in order to be functional.
  • both the housing and the connection adapter can be made from an inexpensive material. Both parts can, if necessary, be made of a higher quality material, e.g. Spheroidal cast iron or steel. This leads to an expansion of the application area of the valve. At the same time, the higher quality materials allow plastic deformation, which makes it possible to provide forming elements for connecting the functional valve unit with connection adapters that may be necessary.
  • the connection adapter When the connection adapter is attached to the fitting unit, it becomes a central part of a longer fitting that can be connected to another connection system. In connection with one or two connection adapters, the valve unit becomes an integral part of a housing, which has a larger overall length that corresponds to another standard.
  • connection adapters are manufactured as separate components. This procedure is based on the knowledge that, compared to the housing enveloping the closure element and its actuating elements, flanges form a significant cost factor because of their large construction volume and the resulting material costs.
  • the flanges are simply designed components that have no special manufacturing requirements. They can therefore be produced as separate components in places where the material and manufacturing costs are cheap. As far as it is economical, this can be, for example, in the country of a customer.
  • valve unit can be installed on site in a workshop with the speaking connection adapters, for example in the form of flanges, flange washers, welded sockets or other separate flange types, can be completed to the desired valve type.
  • connection adapters required for installation in a pipeline are usually rotationally symmetrical and well manageable in terms of the stresses.
  • the material can be cast iron with lamellar graphite. The combination of inexpensive materials enables the production costs to be optimized here.
  • Embodiments of the invention provide for this that a rolled-in collar connects the connection adapter to the fitting unit, or that the collar is an integral part of the housing or the connection adapter.
  • the collar can also be inserted as a ring in the housing and in the connection adapter.
  • the collar is designed as an integral housing component of the valve unit, the collar is removed by machining when using the valve as a clamping valve.
  • an anti-rotation device is arranged between the housing and the connection adapter.
  • This can provide for the use of dowel pins, but an outer diameter of the collar and an adjoining guide section and corresponding counter surfaces in the housing and / or in a connection adapter can also be arranged eccentrically to one another. This ensures precise alignment of the connection adapters to the housing during assembly. This can be essential for flange connections that must be provided with precisely aligned flange bores.
  • the circumferential surfaces of the collar lying against one another and the mating surfaces of the housing or the connection adapter lying against them are provided with a profile. This enables the transmission of axial pipeline forces via the connection point.
  • valve unit When designing the valve unit as a flange valve, it should be noted that the position of the bore in a flange for the connecting means to be guided through it must assume a defined angular position to the axis of the actuating means.
  • an anti-rotation device is arranged between the housing and the connection adapter. This can e.g. B. done by inserted pins or by an eccentric arrangement of fitting holes arranged in series.
  • an outer diameter of the collar and an adjacent guide section and the corresponding counter surfaces in the housing and / or in a connection adapter are arranged eccentrically to one another. This allows one precise axial assembly, but prevents relative rotation of the components to be connected and secures the respective assembly position.
  • connection adapters are usually cylindrical in shape at the connection point, the defined angular position can also be ensured during rolling in by means of an appropriate device, for example by means of an external anti-rotation lock which snaps into a flange bore
  • Another advantage of the invention is the reduction in storage costs.
  • a method for producing a multi-part fitting housing provides for the fitting unit to be designed as a clamping fitting and for connecting the fitting unit to other pipeline connections one or more connection adapters are connected to the valve unit by a rolled-in collar. Further refinements provide for this that a collar producing the connection between the fitting unit and the connection adapter is widened during the rolling in and that a rolling tool is guided through an inflow opening and / or an outflow opening of a connection adapter to the location of the rolling process and that the rolling-in process takes place on a stationary fitting.
