The invention relates to an arrangement for detecting and locating a leakage in a water pipe system, having a water treatment system, having a pump, having a supply line and a drain, having at least one circulation line connected to the supply line and the drain, having at least one inlet valve, at least one outlet valve and at least one pressure sensor in at least one circulation line and/or the supply line and the drain, wherein the inlet valve and the outlet valve are electrically controllable, having control means for controlling the inlet valves and the outlet valves, having detection means for detecting the timewise development of the measured values of the at least one pressure sensor, with evaluation means for evaluating the timewise development of the pressure change and for comparing the amount of the pressure change with a limit value, and with output means for the output of a leakage indicating indication signal if the amount of the pressure change exceeds the limit value. This arrangement solves the technical problem of improving the detection and, if necessary, location of a leakage.

Arrangement and method for detecting leaks in a water pipe system

The disclosure relates to an attachment for a base jaw of a pressing tool for pressing fittings in order to produce pipe connections, comprising an attachment body, a pressing section, formed on the attachment body, to form half of a jaw opening, and comprising a connecting section, formed on the attachment body, for a connection to the base jaw. The technical problem of providing attachments for exchangeable jaws, base jaws and systems which allow an improved use for fittings of different nominal widths is solved in that the pressing section and the connecting section are arranged at a distance from one another. The invention also relates to a base jaw and to a system consisting of at least two pairs of attachments and one pair of base jaws.

Exchangeable jaw for pressing tool

A fitting for a sealing, non-releasable pipe connection, including a main fitting body for accommodating at least one pipe which is to be connected, and at least one pressing sleeve. The main fitting body and the pressing sleeve have pressing surfaces, which are assigned to one another. The main fitting body has a pressing surface which, in the installed state, is directed towards the pipe which is to be connected, and is assigned to a peripheral region of the main fitting body. The pressing surfaces assigned to one another on the main fitting body and on the pressing sleeve are formed such that the action of pushing the pressing sleeve axially onto the main fitting body gives rise to the peripheral region of the main fitting body being narrowed radially.

The invention is based on the technical problem of improving the pressing in of large press fittings, said problem being solved by a device for transmitting a mechanical force for driving a pressing device for press fittings, having a storage container () for hydraulic fluid, having a pump cylinder (), having a working cylinder (), having a first line () for connecting the storage container () to the pump cylinder (), having a second line () for connecting the pump cylinder () to the working cylinder (), and having a third line () for connecting the working cylinder () to the storage container (), wherein means () for preventing a return flow into the storage container () are provided in the first line (), wherein means () for preventing a return flow into the pump cylinder () are provided in the second line (), wherein switching means () for opening and closing the third line () are provided, and wherein the swept volume (VA) of the working cylinder () is configured to be greater than the swept volume (VP) of the pump cylinder (). The invention also relates to a corresponding method.

Device and method for transmitting a mechanical force for driving a pressing device for press fittings

A pressing tool for joining a pipe and a fitting, including two swivel elements for pressing the pipe and the fitting, a receiving region, formed between the swivel elements, for receiving the pipe and the fitting, at least one swivel axis for rotatably mounting the swivel elements, and a tensioning mechanism for pretensioning the pressing tool. The swivel elements can be swivelled towards one another about the at least one swivel axis to press the pipe and the fitting. In a first, closed position, the receiving region is narrower than in a second, open position, of the swivel elements, wherein the swivel elements are pretensioned towards the closed position by the tensioning mechanism. At least one holding device is provided for holding the swivel elements in the open position against the pretensioning force generated by the tensioning mechanism.

Pressing tool with switchblade bistable tensioning mechanism

A press fitting, including a tubular component and an end portion of the tubular component which can be compressed to make a connection. The end portion has an opening to receive a tube and a first region having an annular ridge to receive a sealing ring. A second region is arranged on the side of the ridge adjacent the opening and a third region is arranged on the side of the ridge remote from the opening. The overall wall thickness of the press fitting in the second region is increased at least in a section or sections in comparison with the wall thickness of the tubular component in the third region.

Press fitting and use thereof

A transmission element, which has a permanent nondetachable connection, is producible employing an axial pressing technique using simple means. The transmission element for workpiece connections to be axially compressed includes a flange section and a transmission section. The transmission section exhibits a substantially cylindrical internal peripheral surface, and the wall thickness of the transmission section tapers from the end proximal to the flange section to the end distal to the flange section. The transmission element is manufactured from a heat-resistant plastic.
