Definitions

  • the invention relates to a device for cleaning pipes with an inlet connection for the supply of liquid and an outlet connection for connection to the pipe to be flushed, and with a supply for the compressed air.
  • a water supply and a gas supply are alternately connected to the pipeline via respective valves.
  • the object of the invention is to provide a device of the type described at the outset which is simple in design and with which quick and reliable cleaning is possible.
  • a device of the type described at the outset which is characterized according to the invention by a controller for controlling the compressed air supply and a water meter for measuring the liquid flowing through, the output signal of which is fed to the input of the controller.
  • a pressure regulator is provided, the input of which is connected to the inlet side of the water supply and which is designed in such a way that a preset ratio between liquid pressure and air pressure is achieved. This ensures that the pregiven level air pressure is kept constant even when the water pressure changes, for example during a withdrawal on the inlet side.
  • the pressure regulator is designed as a differential pressure regulator, so that, for example, the air pressure is always greater than the actual water pressure by a predetermined value.
  • the pressure regulator has an oil or water filter in its passage for the compressed air.
  • a compressor is preferably provided on the input side of the compressed air supply and is mounted together with the other components on a chassis. This ensures that the entire facility is mobile and can be moved directly to the place of use, which is particularly important for use on construction sites.
  • the device comprises a pipe section 1 to be coupled between a water supply and the pipeline to be flushed, with an inlet-side connection 2 for connecting to the liquid supply and an outlet-side connection 3 for connecting to the pipeline to be flushed.
  • a water meter 4 is provided in the form of a pulse water meter for measuring the flow.
  • the output side of the pulse water meter is connected to the input of a controller 5.
  • a compressor 6 is also provided.
  • the output side of the compressor is connected to the input of an automatic pressure regulator 8 via a compressed air line 7.
  • the output of the pressure regulator 8 leads via the compressed air line to an inlet of a solenoid valve 9.
  • the outlet of the solenoid valve is connected to the inlet of a throttle check valve 10.
  • the outlet of the throttle check valve leads into the pipe section 1 at a compressed air supply point 11.
  • a check valve 12 is provided, which blocks flow back in the direction from port 3 to port 2.
  • the pressure regulator 8 is designed as a differential pressure regulator.
  • This has a control head 13 which is connected on its underside to a cup-like hood 15.
  • the control head has an inlet 14 to be connected via the pressure line 7 to the compressor 6, which opens into the interior 16 enclosed by the hood 15.
  • an output 17 is provided which is arranged coaxially to the input 14 and which leads to the interior 16 via a bore.
  • an oil or water filter 18 is screwed interchangeably.
  • a check valve 19 is provided between the oil or water filter and the outlet 17. The valve body of this check valve is biased into its locked position by means of a spring 20.
  • the control head is also connected to a pressure chamber housing 22 which forms a pressure chamber 21.
  • the interior of the pressure chamber has an inlet 23 which, as can be seen in FIG. 1, is connected to an outlet of the water meter 4 via a control line 24.
  • a diaphragm 26 is clamped between the pressure chamber housing 22 and the housing of the control head 13 perpendicular to the displacement path of the valve body 25 of the check valve 19.
  • the membrane On the side facing the pressure chamber interior, the membrane is acted upon by a compression spring 27, the other end of which rests against an inner wall of the pressure chamber interior opposite the membrane.
  • the membrane 26 On its side opposite the compression spring 27, the membrane 26 is connected to the valve body 25 via a tappet 28.
  • the pressure of the spring 27 is adjustable by means of a manual setting device 29.
  • a metering pump 30 is also provided, which is connected on the inlet side to a suction lance 31 for sucking in metering agent and on the outlet side via a check valve 32 to the pipe section 1 or an additional pipe section 33 to be coupled in.
  • the metering pump 30 and the suction lance 31 are connected to the controller 5 via control lines and a connector plug 34 via a corresponding connection socket 35 and corresponding control lines.
  • water flows through the pipe section 1 via the inlet-side connection 2.
  • the water meter 4 gives electrical pulses to the electronic control 5 depending on the flow rate. This controls the solenoid valve 9 and thus connects or disconnects the compressor 6 to the compressed air supply point 11.
  • the compressed air flows through the throttle check valve 10 into the pipe section 1.
  • the water flow is interrupted for the duration of an incoming air pulse, and the water is mixed with compressed air. Since the inlet-side water pressure is applied to the pressure chamber 21 via the control line 24, the required air pressure is automatically regulated as a function of the prevailing water pressure.
  • the dimensioning of the size of the diaphragm 26 and the strength of the compression spring 27 is selected so that when the water pressure in the pressure chamber 21 is present, the shut-off valve 19 opens so far in the manner shown in FIG 17 there is an air pressure which is higher than the existing water pressure by a predetermined value.
  • the air pressure is preferably one bar higher than the existing water pressure, for example.
  • an air manometer 36 and a water manometer 37 are also provided, on which the prevailing pressures can be read.
  • the controller 5 is designed so that the device described above can be operated in four different operating positions. First, the device can be operated as a normal compressor. The air is led directly from the compressor 6 to the consumption point.
  • a third operating position chemicals are dosed in addition to the pipe rinsing.
  • the metering device 30 and the suction lance 31 are controlled like a conventional metering device via the controller 5 as a function of the water meter 4 for the quantitative metering of a chemical into the pipe section 1 or the pipe section 33.
  • the compressor is switched off in one switching position, while it is also switched on in another operating mode.
  • the entire device with the compressor 6 with an associated pressure vessel 38, the controller 5, the water meter 4, the pressure regulator 8 and the pipe section 1 with its connections is mounted on a chassis 39. In this way it is possible to drive the entire device with this chassis directly to the place of use and to put it into operation immediately after connecting it to the pipe to be flushed.
