Definitions

  • the present invention relates to a pipe separator according to the preamble of claim 1.
  • Such a pipe separator or backflow preventer can e.g. can be taken from DE-PS 27 51 468 or DE-OS 33 09 318.
  • the pipe separator according to DE-OS 33 09 318 differs from the pipe separator according to DE-PS 27 51 468 only by the arrangement of a booster piston connected to a sealing piston, which are acted upon in the same way by the pressure of the inflowing medium, so that an increased closing force with regard to the sealing piston results.
  • Pipe separators are fittings that are installed in a water line and are intended to prevent non-drinking water from flowing back into the drinking water supply line. If there is a risk that non-drinking water can flow back into the drinking water supply line or be sucked back, the pipe separator must block access to the drinking water line and at the same time vent the downstream system to the atmosphere. In order to prevent backflow with certainty, this ventilation must be initiated at a distance of 0.5 bar before the critical pressure is reached.
  • the pipe separator be installed with a suitable circuit so that it normally remains in the disconnected position and only goes into the flow position when water is actually required.
  • This mode of operation is normally achieved by installing a shut-off valve in the supply line to the pipe separator and a relief or blow-off valve between the shut-off valve and the pipe separator. When the shut-off valve is closed, the relief valve must open at the same time. This is the pipe section between the shut-off valve and pipe separator depressurized and the sealing piston of the pipe separator moves into its disconnected position.
  • shut-off valve When the shut-off valve is closed, the relief valve must open at the same time. This is the pipe section between the shut-off valve and pipe separator depressurized and the sealing piston of the pipe separator moves into its disconnected position.
  • additional costly, automatically operating shut-off valves are required.
  • the upstream shut-off valve built into the main line represents an additional flow resistance and thus reduces the pressure available after the pipe separator.
  • oxygen is introduced through the necessary ventilation of the pipe section between the shut-off valve and pipe separator, which can lead to faults in the downstream system.
  • FIG 1 shows the installation of a pipe separator 10 of a known type, as it is to be installed in the so-called "installation type 2" according to DVGW worksheet W503.
  • installation type 2 the pipe separator only goes into the flow position when water is actually drawn.
  • measures are taken so that the pipe separator goes into the disconnected position at least once a day.
  • the control circuit then excites a shut-off valve 12 connected to the supply line to the pipe separator 10 at certain points in time, a blow-off valve 14 which is excited at the same time venting the pipe string between the pipe separator 10 and the shut-off valve 12.
  • This known system has the disadvantages mentioned at the outset.
  • the pipe separator 10 'modified according to the invention has a cross-shaped housing 16, in which a first valve seat 22 is arranged between an inlet connector 18 and an outlet connector 20. Coaxial with this first valve seat 22 there is a second valve seat 24 which is offset downwards.
  • a tubular sealing piston 26, which is closed at the top, is displaceable in both valve seats 22, 24 and has the same diameter and forms a non-return valve with the first valve seat 22 and with the second Valve seat 24 a drain valve.
  • the drain valve 24, 26 opens into a drain port 28, under which a collecting funnel 30 is arranged.
  • a loading spring 34 is supported, which acts on the sealing piston 26 in such a way that it is moved into a position closing the non-return valve 22, 26.
  • a check valve of known type 36 is arranged in the outlet connection 20 and prevents the subsequent line string from being emptied when the check valve 22, 26 is closed, its venting but allowed.
  • a relief piston 40 which is guided in a sealed manner in the housing 16, is connected to the locking piston 26 via a rod 38.
  • An inwardly projecting collar in the housing 16 limits the displacement of the closure piston 26, rod 38 and relief piston 40 upwards.
  • the space above the relief piston 40 is connected to the inlet pressure p 1 via a first line 42 and to the atmosphere via a second line 44.
  • the liquid located in the space above the relief piston 40 can be discharged via the line 44 and a collecting funnel 46 arranged underneath.
  • a solenoid valve 48 sits on the cross-shaped housing 16.
  • the solenoid valve 48 has a rocker arm 52 which is mounted about a pivot point 50 and which carries on one side a closing body 54 which interacts with the two lines 42 and 44 in order to close a three-way valve form.
  • the rocker arm 52 is biased by a spring 56 in a position closing the line 42.
  • a winding 60 arranged in a U-shaped pole shoe 58 acts on the rocker arm 52 when it is excited and pivots it in order to close the line 44 leading into the atmosphere and to release the line 42 connected to the inlet pressure p 1 .
