Definitions

  • the invention relates to a device for flushing and / or for pressure and leak testing of lines, in particular of drinking water and / or heating systems.
  • Analog and digital pressure test devices are known with which lines can be tested for pressure and tightness.
  • the devices are equipped with hand pumps with which a certain pressure can be applied.
  • the regulations prescribe ever higher pressures for pressure and leak tests.
  • such pressures can no longer be generated with the hand pumps.
  • the pamphlet CA-A1-2 639 600 discloses a device for checking valves, the device having a line with a water connection, an air connection and an outlet for connection to the valves to be checked. There is a valve in the water connection and the air connection.
  • the invention is based on the object of designing the generic device in such a way that it can be used to carry out the necessary flushing and / or testing of the line systems in a cost-effective and simple manner.
  • the device preferably has at least one pressure generator which is arranged on the base frame and can apply the high pressure required for testing according to EN 806-4.
  • the device is equipped with a compressor and / or a pump for this purpose.
  • the required test pressure can be generated with these pressure generators. Therefore no additional devices are required in addition to the device. The craftsman can therefore easily carry out the necessary tests on the pipeline systems.
  • the pressure generator can be used for pressure testing with air or for pressure testing with water.
  • the device has at least one water line which is provided with a connection for the water network and with an outlet to which, for example, a hose can be connected which connects the device to the line system to be tested.
  • At least one compressed air line via which compressed air can be supplied, opens into the water line. This makes it possible to introduce a water-compressed air mixture into the pipe system. This procedure is used when flushing the pipe systems. Since the switching valve is located in the compressed air line, the access of the compressed air to the water line can be released or blocked as required. It is therefore possible with the device, either with just water or with one Water-compressed air mixture to flush the lines.
  • the switching valve is advantageously a 3/2-way valve.
  • the compressed air can be supplied continuously or in pulses.
  • the user of the device according to the invention thus has the option, depending on the existing conditions, of selecting the most favorable flushing method with and without compressed air, with the compressed air also being supplied continuously or in pulses.

  • the bearing pieces 67 are provided such that the legs 63, 64 strike the webs 68 of the bearing pieces 67 when the bracket 62 is pivoted up. As a result, the pivoting path of the bracket 62 is limited in a simple manner.
  • the bearing pieces 67 are located approximately at the level of the connection areas of the cross strut 15 on the two frame parts 5, 7.
  • the two cross struts 14, 15 are thus on the frame parts 4, 6; 5, 7 attached so that they protrude slightly beyond this to the outside. They therefore offer impact protection if the device should hit a wall, table and the like while driving, for example.
  • the cross struts 14, 15 thereby protect the base frame 1 and / or the components of the device.
  • the base frame 1 is designed so that it can accommodate the amounts of compressed air required for testing purposes.
  • the capacity of the base frame 1 is selected so that it can hold 5 liters of compressed air.
  • the base frame 1 can also be designed for a larger or smaller amount of compressed air.
  • the Compressed air tank no separate compressed air tank is required, the described design of the base frame 1 as a compressed air tank contributes particularly to the compact design of the device, which has a low center of gravity due to the construction described.
