Definitions

  • the invention relates to a system separator according to the preamble of claim 1.
  • a system separator is known with a housing, the housing of which defines an inlet chamber, an intermediate chamber and an outlet chamber, wherein the system separator further comprises two positioned in the housing, in the direction of flow of a medium in series, a backflow preventer, namely a first, inlet-side backflow preventer, which between the inlet chamber and the intermediate chamber is connected, and a second outlet-side non-return valve, which is connected between the intermediate chamber and the outlet chamber.
  • the system separator disclosed therein comprises a bleed valve with which the intermediate chamber between the two non-return valves can be vented or discharged, wherein the bleed valve is controlled depending on a differential pressure between the pressure in the inlet chamber and the pressure in the intermediate chamber. Then, when this differential pressure drops below a defined limit, the drain valve opens to vent the intermediate chamber into the atmosphere.
  • U1 is another system separator with an inlet-side backflow preventer connected between an inlet chamber and an intermediate chamber, an outlet-side non-return valve connected between the intermediate chamber and an outlet chamber and having a drain valve
  • the housing of the system separator is formed as a two-part housing, which first, upper housing part and a second, lower housing part comprises.
  • the first housing part of the system separator is the DE 20 2005 020 081 U1 to a first line, in particular to a dedicated line, or to a pre-pressure zone coupled.
  • the second housing part receives the two backflow preventer and serves to connect the system separator to a second line or to a back pressure zone.
  • the two housing parts of the housing of the system separator are screwed together according to this prior art, including the first, upper housing part has a portion with an external thread and the second, lower housing part has a portion with an internal thread, which engage in the screwing. It follows that the two housing parts can be connected together only in a single defined relative position, which is determined by the intermeshing threads.
  • Another system separator is from the DE 20 2009 016 823 U1 known, wherein in this system separator a one-piece housing is provided, and wherein the inlet chamber of the system separator is associated with a shut-off valve, via which the inlet chamber can be separated from a pre-pressure zone.
  • a generic system separator is from the GB 1 374 833 A known.
  • the DE 0 166 203 A2 discloses a fitting for a gas and / or liquid pipe.
  • the EP 2 431 515 A1 discloses a drain hose of a washing machine.
  • the invention is based on the object to provide a novel system separator.
  • the system separator according to the invention has the advantage that the two housing parts can be fixed to each other in any rotational position to each other. For this purpose, adjacent sections of the two housing parts are simply plugged into each other and therefore not screwed together as usual in the prior art, wherein a securing element fixes the two housing parts in any relative rotational position to each other. This is advantageous in the arrangement of the system separator under confined spaces. After releasing the securing element, the two housing parts of the system separator can be pulled apart, in which case the positioned between the nested sections of the two housing parts filter element of the system separator is accessible.
  • the fixation of the two housing parts via the securing element, which at least partially engages in the two circumferential securing grooves of the two nested sections of the two housing parts, is particularly simple and preferred.
  • Fig. 1 to 5 show different views of a first inventive system separator 10, wherein such a system separator 10 comprises a housing 11, which defines an inlet chamber 12, an intermediate chamber 13 and an outlet chamber 14.
  • a plurality of backflow preventers are connected one behind the other in the flow direction of a medium, namely a first backflow preventer 15 between the inlet chamber 12 and the intermediate chamber 13 and a second backflow preventer 16 between the intermediate chamber 13 and the outlet chamber 14.
  • a drain valve 34 is accommodated in the housing 11 which can ventilate the intermediate chamber 13 into the environment depending on a differential pressure between the pressure in the inlet chamber 12 and the pressure in the intermediate chamber 13.
  • the details and the operation of the two backflow preventer 15, 16 and the drain valve 34 are familiar to the person skilled in the art and need no further explanation.
  • the housing 11 of the system separator 10 is designed in several parts, wherein a first housing part 17 of the connection of the system separator 10, namely the inlet chamber 12 thereof, to a first line or to a pre-pressure zone, and wherein the second housing part 18, preferably both backflow preventer 15, 16 as well as the drain valve 34 receives and the connection of the system separator 10, namely the outlet chamber 14 thereof, to a second line or to a back pressure zone is used.
  • the first housing part 17 has a flange 19 with an external thread 20 for screwing the system separator 11 to the first line or the pre-compression zone
  • the second housing part 18 has a flange 21 with an external thread 22 to the system separator 11 to the second line or to connect the back pressure zone.
  • a filter element 26 is positioned between the nested sections 23 and 24 of the two housing parts 17, 18, a filter element 26 is positioned. After loosening the securing element 25 and pulling the two housing parts 17, 18, the filter element 26 is easily accessible, for example, for maintenance or replacement of the filter element 26 and that without the housing parts 17, 18 of the lines or of the pre-pressure zone and the Back pressure zone must be dismantled.
  • the nested sections 23 and 24 of the two housing parts 17, 18 of the housing 11 of the system separator 10 each have a circumferential securing groove 27 and 28, respectively. Then, when the two sections 23, 24 of the two housing parts 17, 18 are inserted into each other, the two securing grooves 27 and 28 concentrically surround each other, wherein the securing element 25 for fixing the two housing parts 17, 18 to each other by both concentrically enclosing and circumferential securing grooves 27, 28 extends in sections.
  • the portion 24 of the second, lower housing part 18 is inserted into the portion 23 of the first, upper housing part 17, wherein when the two sections 23, 24 of the two housing parts 17, 18 are inserted into each other, the securing groove 27 of Section 23 of the first, upper housing part 17 radially outward and the securing groove 28 of the second, lower housing part 18 is positioned radially inward, so that accordingly the securing groove 27 of the upper housing part 17 and the section 23 thereof the securing groove 28 of the lower housing part 18 and of the section 24 of the same radially outwardly concentrically surrounds.
  • the wall 29, which has the recesses 30 for the passage of the securing element 25 and which separates the two securing grooves 27, 28, from the portion 23 of the first, upper housing part 17 is then provided.
  • the securing element is designed as a U-shaped bracket, wherein mutually parallel webs 35 of this clip extending through the recesses 30 in the wall 29, so that these parallel webs 35 of the securing element 25 in sections by both circumferential securing grooves 27th , 28 extend.
  • the recesses 30 are in such a way in which the two securing grooves 27, 28 separating wall 29 introduced that the parallel webs 35 of the clip-like securing element 25 which extend through these recesses 30, the portion 24 of the lower housing part 18 of the housing 11 in itself comprise approximately diametrically opposite positions.
  • a check valve 31 is integrated into the first, upper housing part 17 of the housing 11.
  • the pre-pressure zone can be separated from the inlet chamber 12 of the system separator 11 via the shut-off valve 31.
  • the lower housing part 18 can then be separated from the upper housing part 17 and the filter element 26 can be accessed by removing the securing element 25 without the risk of medium escaping from the pre-compression zone.
  • the integration of the check valve 31 in the first, upper housing part 17 of the housing 11 of the system separator 10 is preferred, it is also possible, the first upper housing part 17 exclusively for connecting the system separator 11 to a line or to a pre-pressure zone or at to use a separate shut-off valve.
  • the first, upper housing part 17 exclusively provides the connection function for connecting the system separator 10 to a line or to a shut-off valve.
  • a sealing ring seal member 32 is inserted into a groove 33 of the portion 24 of the lower housing part 18, wherein in the nested state of the two housing parts 17, 18, this groove 33, which receives the sealing member 32, axially spaced from the concentrically surrounded locking grooves 27, 28 ,
