Abstract

Systemtrenner (10), mit einem eine Einlasskammer (14), eine Zwischenkammer (15) und eine Auslasskammer (16) definierenden Gehäuse (11), mit in dem Gehäuse (11) positionierten, in Durchflussrichtung eines Mediums hintereinander geschalteten Rückflussverhinderern, nämlich einem einlassseitigen Rückflussverhinderer (12) und einem auslassseitigen Rückflussverhinderer (13), und mit einem die Zwischenkammer (15) belüftenden Ablassventil, welches abhängig von einem Differenzdruck zwischen dem Druck in der Einlasskammer und dem Druck in der Zwischenkammer gesteuert ist, wobei jeder Rückflussverhinderer einen Düsenkörper (19) mit mindestens einem Ventilsitz, einen Ventilteller (20) und ein Federelement (21) umfasst, wobei der Düsenkörper (19) des einlassseitigen Rückflussverhinderers und der Düsenkörper (19) des auslassseitigen Rückflussverhinderers identisch ausgebildet sind und jeweils zwei Ventilsitze aufweisen, nämlich jeweils einen ersten Ventilsitz (23), der dann aktiv ist, wenn der jeweilige (19) am einlassseitigen Rückflussverhinderer (12) verbaut ist, und jeweils einen zweiten Ventilsitz (24), der dann aktiv ist, wenn der Düsenkörper am auslassseitigen Rückflussverhinderer (13) verbaut ist. (Fig. 1)

A system separator (10), comprising a housing (11) defining an inlet chamber (14), an intermediate chamber (15) and an outlet chamber (16), with non-return valves positioned in the housing (11) in the flow direction of a medium, namely an inlet side Backflow preventer (12) and an outlet-side backflow preventer (13), and with the intermediate chamber (15) venting discharge valve, which is controlled depending on a differential pressure between the pressure in the inlet chamber and the pressure in the intermediate chamber, wherein each backflow preventer, a nozzle body (19 ) comprising at least one valve seat, a valve plate (20) and a spring element (21), wherein the nozzle body (19) of the inlet-side backflow preventer and the nozzle body (19) of the outlet side backflow preventer are identical and each having two valve seats, namely in each case a first Valve seat (23), which then active i st, when the respective (19) is installed at the inlet-side non-return valve (12), and in each case a second valve seat (24), which is active when the nozzle body at the outlet-side non-return valve (13) is installed.
