  • the input-side backflow preventer preferably also the output-side backflow preventer are in each case preferably designed and arranged such that their actuation depends solely on the effective fluid pressures, but not on a manually adjustable by the user operating state.

  • the ventilation element can also serve alone the outflow of the liquid fluid from the annular channel, whereas the tracking of air in the thus emptied annular channel is allowed through another opening.
  • the ventilation element serves both the drainage of the annular channel and the supply of air into the annular channel and accordingly preferably communicates with the atmosphere on the side facing away from the annular channel.

As axial movement of the spindle 36 progresses, an actuating cam 37 formed on the outer circumference of the spindle 36 abuts against the actuating mandrel 60 and tilts the dewatering element 59 into an open position so that water is discharged from the annular channel 84 into the drainage cage 44 via the bypass channel 58 can.

  • the seal 76 With progressive advancing movement and after installation of the seal 76 against the valve seat 14, the axial feed of the spindle 36 is compensated by the compression of the coil spring 42.

  • the output-side backflow preventer 55 In the case of a pressure difference due to a hose connected to the hose connection piece 54, for example a high-pressure cleaner, the output-side backflow preventer 55 usually first becomes effective. Should this nevertheless be bridged, so that fluid flows against the actual flow direction in the direction of the outlet housing 30, closes the input-side backflow preventer 47.

  • P1 is the pressure in the pre-chamber V and P2, the pressure in the central chamber M. This vote ensures that the input-side backflow preventer 47 can only get fluid into the central chamber M in the direction of flow of the valve, if a sufficient pressure difference between the prechamber V and the middle chamber M prevails.

  • the water flows via the drain valve 50. Only with progressive advancing movement of the spindle 36, the dewatering element 59 is actuated in the manner described above to derive water from the prechamber V.
  • the area between the middle chamber M and the outlet A is closed to the environment. This allows a review of the operability of the system separator cartridge with the input side backflow preventer 47 and the output side backflow preventer 55.

  • a varying internal pressure can now be set to evaluate the function of the system separator cartridge 51 at such pressure differentials. The same applies to the pressure difference across the outlet-side non-return valve 55.
  • a pressure measuring probe is mounted in the region of the outlet. It goes without saying that for such measurements, the output must be hermetically sealed.
  • the central chamber M can be completely closed by the inlet-side backflow preventer on the one hand and on the other hand by the outlet-side backflow preventer 55 in order to reliably apply the desired test pressure over the test neck.
  • the Figures 3 and 4 show an alternative embodiment.
  • the essential parts of the outlet fitting are identical and as far as possible marked with identical reference numerals. Contrary to the embodiment described above, the second embodiment has no bypass channel. Rather, the water discharged from the annular channel 84 after the shut-off of the fitting is discharged through the inlet-side non-return valve 47.
  • a designated by reference numeral 61 reflux valve body of the system separator cartridge 51 on an extended actuating mandrel 60.
  • the non-return valve body 61 is usually under tension of a spring 62 to an associated valve seat 63 of the system separator cartridge 51 at.
  • the Figures 3 and 4 show the open position, in which the backflow preventer valve body 61 is pressed against the biasing force said spring 63 in the open position due to the water pressure.
  • the system separator cartridge 51 is provided so that at lower pressure in the prechamber V, the inlet side backflow preventer 57 of the system separator cartridge 51 blocks the passage between the prechamber V and the middle chamber M and at the same time a discharge of water from the Middle chamber M allows.
  • the actuating mandrel 60 projects into the prechamber V before.
  • the spindle 34 has a radially projecting collar 64, which is arranged in the open position of the shut-off valve between an axial extension of the actuating mandrel 60 and the rotary handle 40. To shut off the valve, the spindle 36 is presented in a manner known per se in the direction of the valve housing 10, taking with it the intermediate spindle 70.
  • This design also ensures that the valve is first shut off and opened only after complete shut-off by forced operation due to the further and continued adjusting movement of the spindle 36 of the input-side backflow preventer 47 and a discharge of the liquid is possible. If the spindle 36 remains in this position after opening the input-side non-return valve 47, forced ventilation or forced drainage of the annular channel 84 is permanently ensured even if fluid is pushed back, for example through the hose connection piece 84 in the direction of the valve and the output-side backflow preventer 55 for whatever reason interspersed.
  • the frost-proof fitting according to the invention provides greater security against contamination of fluid, which is initially outside the shut-off valve. This is prevented with greater certainty that such fluid is pressed back into a fresh water line to which the valve is connected, whereby the fresh water would be contaminated.
