The water saving device consists of an input valve (E), a fin (), which rotates with the water flow and which rotates the reduction gear toothed wheels (1, 2, 3, 4, 5) a disconnection gear (A), an immediate disconnection gear (B), a disconnection gear (), an immediate disconnection gear (B), an output valve () and two control levers (M1, M2). The device is placed after the hydrometer and before the installation, cutting off the water in case of unwise consumption. The device may also be used in larger installations (in the proper size), e.g. dams or irrigation works. We must not keep the tap continuously open, but we should be closing it at times. When we forget and leave the tap open, or, if there is damage at the installations, then the device cuts off the water supply. We bring the water back with the control lever (1). In case of our absence from home, we activate the immediate disconnection gear, so that the water may be cut off as soon as a small quantity of water passes through. |
