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.
