A drinking water supply system with a drinking water line system includes multiple drinking water removal points connected to the drinking water line system, at least one sensor, which is designed to determine measurement values, and a central controller, which is designed to receive and evaluate measurement values determined by the at least one sensor. Multiple sensors are provided which are designed to determine measurement values for one property or for different properties of the water being conducted in the drinking water supply system at different locations in the drinking water supply system, and the central controller is designed to receive and evaluate the measurement values determined by the sensors. One or more of the sensors is designed to determine measurement values for the drinking water quality of the water being conducted in the drinking water supply system. A method for controlling such a supply system is also provided.

Drinking water supply system with drinking water quality monitoring function, method for controlling same, and computer program

The invention relates to a drinking water supply system including a drinking water line system, a plurality of drinking water withdrawal points connected to the drinking water line system, at least one sensor which is designed to determine measuring values, a central control device which is designed to receive and evaluate the measuring values determined by the at least one sensor, a plurality of decentralized control elements which are designed to influence at different locations in the drinking water supply system one or more properties of the water guided in the drinking water supply system, wherein the central control device is designed to control the control elements for influencing the one or more properties of the water guided in the drinking water supply system, and wherein a plurality of control elements are or can be combined to form a virtual group.

A drinking water supply system includes a drinking water line system, a plurality of drinking water withdrawal points connected to the drinking water line system, at least one sensor which is designed to determine measuring values, and a central control device which is designed to receive and evaluate the measuring values determined by the at least one sensor. The system also includes a presence detector designed to determine information about the presence of a person, or an acoustic sensor designed to measure measuring values for the volume. The central control device is designed to control the drinking water supply system as a function of the information about the presence of a person or as a function of the measured values for the volume. A method for controlling such a drinking water supply system and a computer program that causes the method to be carried out are also provided.

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

A drinking water supply system with a drinking water line system includes multiple drinking water removal points connected to the drinking water line system, at least one sensor, which is designed to determine measurement values, and a central controller, which is designed to receive and evaluate the measurement values determined by the at least one sensor. The central controller is designed to control the control elements depending on the received measurement values. The drinking water line system has a drinking water line section for supplying drinking water to multiple drinking water removal points. A volumetric flow rate sensor is provided in order to measure the volumetric flow rate of the water in the drinking water line section and/or a pressure sensor is provided in order to measure the water pressure in the drinking water line section. The controller is designed to carry out a measure.

A shut-off valve for the plumbing sector for shutting off a line through which a fluid can flow that preferably includes a housing having at least two connecting pieces. A flow path is defined from one of the connecting pieces through the housing to another of the connecting pieces, and a shut-off body is disposed rotatably in the housing with a single shut-off section running crosswise to the flow path. Preferably, the shut-off segment is constituted as a spherical segment, and the shut-off body can be moved between a closed position in which the flow path is completely blocked to only one of the connecting pieces and an open position in which the flow path is completely clear. A switching shaft which is rotatably mounted in the housing and is connected in a rotationally fixed manner at its one end to the shut-off body.

Shut-off valve for the plumbing sector

The invention relates to a check valve for blocking a fluid-carrying line in case of reversal of the flow direction, containing a valve housing defining a flow path and having two connecting pieces and a valve seat therebetween, and a flap module mounted in the valve housing and containing a shut-off body interacting with the valve seat, a bearing device for pivotably supporting the shut-off body such that the latter is movable between an open position and a closed position, and a lever extending between the shut-off body and the bearing device and being connected to the shut-off body and the bearing device. For easier manufacturing, the invention proposes that a part of the flap module is formed by at least one sheet-metal shaped part.
