Abstract: Device for treating water with a supply (3); a treatment tank (4); a drain (9); a regulator (13); and a bypass (22) which connects the supply (3) to the drain (9), characterised in that in the main canalisation (2), on either side of the regulator (13), is provided a shut-off valve (12, 14); in that the device (1) comprises a first shunt canalisation (18) which bridges the first shut-off valve (12) and the regulator (13) and comprises a second shunt canalisation (20) which bridges the regulator (13) and the second shut-off valve (14), whereby both shunt canalisations (18, 20) comprise a shut-off valve (19, 21), and whereby the shut-off valves (12, 14) are open on either side of the regulator (13) during the treatment phase, whereas the other shut-off valves (19, 21) are open during the rinse or regeneration phase.

Abstract: The invention relates to a device 1 for treating a fluid, including a container 2,3 with inner space, at least one entrance to the inner space arranged on the container, wherein the entrance includes a first and second opening 4,5, a grid body 14 which is arranged in the inner space and which divides the inner space into a first compartment for a treatment arrangement, preferably filter material, connected to the first opening 4 and at least one second compartment which is connected by means of a tube 25 to the second opening 5 and which is free of filter material. The tube has a connector arrangement for connecting the second opening to the first compartment.

Abstract: Safety valve, characterized in that it principally consists of a housing (1), provided with an inlet (2) and and outlet (3); a main cut off valve (4) installed in the housing (1); and means working together with the flow of liquid which with the removal of liquid and after a lapse of time shut the main cut off valve (4), which are reset in their starting position each time an equal or almost equal pressure in the liquid is created at the inlet (2) and outlet (3) of the safety valve and which when the main cut off valve (4) is shut, hold it shut as long as a well defined drop of pressure remains in existence over the main cut off valve (4), whereby these means are driven by means of a by-pass, such by means of a channel (6) that is situated apart from the main passage (5).

Abstract: The safety device makes it possible to cut the water supply off quickly when there is a very low flow of water such as occurs when there is a leak, to cut off the water supply after predetermined time with normal water consumption, and to cut the water supply off very quickly when a certain predetermined maximum flow is exceeded as would occur with a fractured pipe. The safety device is automatically returned to its initial position when the water consumption is stopped and the shut off is first indicated by a significant reduction in flow. The device can also be manually returned to its initial position after a shut-off.
