Definitions

  • Such a fitting is known from DE-A 3 442 748.
  • an inlet valve is connected upstream of the pipe separator, the actuating piston of which can optionally be connected to the inlet pressure or to the atmosphere via a pilot valve depending on the pressure conditions at the inlet and outlet of the valve.
  • a holding valve arranged in a bypass to a non-return valve serves to avoid switching vibrations, and a pilot valve also serves to vent the pipe string between the inlet valve and the pipe separator when the inlet valve is closed.
  • the non-return valve 32 goes into the blocking position shown, and the pressure equalization valve 68 is used to equalize the pressure on the inlet side and the pressure on the outlet side. If the pressure is equal, however, the spring 46 of the pressure comparison device 40 brings the 3-way valve 38 into a position via the actuating rod 72, in which the space above the relief piston 36 is vented, so that the pipe separator returns to the disconnected position, in which the check valve 18, 22 is closed.
