FIELD: water supply.
SUBSTANCE: device relates to water supply and can be used for automatic shutdown of water supply to water supply and sewage system of a separate room in case of its emergency flooding. Device comprises a flow chamber with locking element 16 connected by element 13 of the movable part of the device with accumulator 14, 15, and stopper 34. Accumulator is made in the form of coaxial bellows 14, 15 connected by element 13 of movable part, one of which is compressed, and the other one is stretched, at that, inner cavities of bellows are part of flow cavity. Stop 34 prevents the change in the position of locking element 16 from open for movement of water to closed under the action of the accumulator. It is connected on one side with handle 25 of the movable part of the device, on the other side - with fixed part 35 of the device, while being subjected to a stretching force and losing its locking function when interacting with emergency water.
EFFECT: invention provides compactness, absence of periodic maintenance and increased reliability.
