Definitions

  • the invention relates to a device for flushing and for testing the pressure and tightness of pipes in drinking water and/or heating systems.
  • Analogue and digital pressure testers 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 the pressure and leak test.
  • such pressures can no longer be generated with hand pumps.
  • it is necessary to use electric pumps in addition to the devices which not only require an additional, expensive device, but also complicate the testing process due to the cumbersome handling.
  • 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 each of 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 required flushing in a cost-effective and simple manner and/or tests of the piping systems can be carried out.
  • the device preferably has at least one pressure generator, which is arranged on the base frame and can apply the high pressure required for the test 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 according to the invention. The craftsman can therefore easily carry out the necessary tests of the line systems.
  • the pressure generator can be used for the pressure test with air or for the pressure test 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 a hose can be connected, for example, 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 line system. This procedure is used when flushing the pipe systems. Since the switching valve is located in the compressed air line, access of the compressed air to the water line can be released or blocked as required. It is therefore possible with the device to flush the lines either with water alone or with a mixture of water and compressed air.
  • the switching valve is advantageously a 3/2-way valve.
  • the compressed air can be supplied continuously or else in pulses.
  • the user of the device according to the invention has the option, depending on the existing conditions to select the most favorable flushing method with and without compressed air, whereby the compressed air can also be supplied continuously or in pulses.
  • At least one compressor is located in the compressed air line, with which the compressed air pressure required for the respective application can be easily generated.
  • At least one compressed air tank is advantageously connected downstream of the compressor. This ensures that a sufficient amount of compressed air is available as soon as the device is switched on. With the compressor, the compressed air tank can be refilled with compressed air in a simple manner.
  • Another compressed air line is connected to the switching valve. It is provided with a connection to which the line system to be tested can be connected with a hose or similar. A pressure test with compressed air is therefore possible via this connection. In the other compressed air line sits another switching valve with which the other compressed air line can be opened or blocked, depending on the test to be carried out by the user of the device.
  • the further switching valve advantageously forms a changeover switch for a pressure test with air or with liquid, preferably with water. Depending on the switching position of this additional switching valve, the user of the device can select the medium required for the test.
  • the further switching valve is preferably a 3/2-way valve.
  • an air supply line is connected to the further switching valve, which in turn connects this further switching valve to a pressure generator for the liquid medium.
  • the device can thus be switch from a pressure test with air to a pressure test with liquid, especially water.
  • the compressed air tank is formed by a base frame of the base frame of the device according to the invention.
  • the base frame is correspondingly hollow and pressure-tight. A separate container to be attached to the base frame, which would require additional installation space, is therefore not required as a compressed air container.
  • the base frame is already provided on the device, so that no additional installation space is required. As a result, the device according to the invention can be made very compact.
  • the base frame is advantageously mirror-symmetrical to the longitudinal center plane of the base frame.
  • This design of the base frame enables the various components of the device to be mounted in a space-saving manner and contributes to a compact design.
  • this design allows the center of gravity of the device to be set favorably.
  • the base frame has two U-shaped frame parts which are arranged upright and merge into one another by two horizontal frame parts.
  • the U-shaped frame parts are advantageously provided opposite one another on the device.
  • the legs of these frame parts advantageously extend downwards, so that the horizontal frame parts are arranged in the lower area of the device.
  • This training contributes to a favorable low center of gravity of the device, making the handling of the device is much easier.
  • the base frame with the frame parts can be produced very easily because tubes can be used as the starting material, which can be easily bent into the desired shape and then connected to one another in a pressure-tight manner in a suitable manner, for example by a welding process.
  • the U-shaped frame parts are advantageously bent in such a way that they have a part of the horizontal frame parts.
  • the horizontal frame parts of the two U-shaped frame parts are welded together, resulting in the base frame.
  • a floor is advantageously fastened to the horizontal frame parts of the base frame.
  • the various components and units of the device can be mounted on it.
  • the base frame thus not only has the function of a compressed air tank, but also serves as a supporting frame with which the components mounted on the floor and/or on the base frame are carried.
  • a standing partition wall is arranged on the floor.
  • the partition wall can be designed in such a way that it optimally shields the components on one side and on the other side from one another, so that these components cannot influence one another.
  • the dividing wall can be designed as a heat protection wall, which ensures that the heat generated by individual units during operation of the device is dissipated in such a way that other components are not affected by the heat.
  • the device can be constructed in such a way that the heat-insensitive components are located on one side of the partition wall, while the heat-generating components, such as the compressor or the pump, are arranged on the other side.
  • the partition wall is also suitable as a mounting wall to which the components of the device can be attached.
  • the switching valves are advantageously connected to a controller. With the control, the switching valves can be switched by the operator to the desired extent.
  • the device is advantageously provided with at least one control panel with input elements for input of data and/or commands into the controller.
  • the user can make the necessary entries for the respective application on the control panel. For example, he can set the device for a flushing process or for a pressure and leak test.
  • the device can also have a connection for an air-powered tool.
  • This connection is advantageously connected to the compressed air tank.
  • the user of the device has the option not only of flushing or checking the line systems, but also of carrying out any installation work associated with the laying of lines using appropriate tools operated by compressed air.

  • the bearing pieces 67 are provided in such a way 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 to the two frame parts 5, 7.
  • the two cross struts 14, 15 are 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, a table and the like while driving, for example.
  • the cross braces 14, 15 thereby protect the base frame 1 and/or the components of the device.
  • the base frame 1 is designed in such a way that it can accommodate the quantities of compressed air required for testing purposes.
  • the capacity of the base frame 1 is chosen 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. Since no separate compressed air tank is required for the compressed air tank, 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 described design.
