Useful model relates to sanitary-technical systems of domestic vodoi gas supply, is directed to provision of safe operation of real estate objects, as individual (house, flat and T. u.) and public use (offices, cafes, Hotels, devices for insertion, baby pre-school facilities and T. u.), in other words prevention of incidents and accidents, associated with operation of these systems, in the period of time, when behind systems is excluded control on the side of the human being, on prevention of flooding water (filled with gas) rooms of dwelling and public buildings off-standard mode of operation of tap (pipeline) network, which take place in a result of not tightness of pipeline systems or in case of left open vodorazbornogo or gazarazbornogo cranes, and also on saving of flow rate of consumed water, gas, electric power, reduced number of discharge in system sewage household sewage and increase working resource electromagnetic coil of the valve, and as solenoid valve main time of day is deenergized and is in closed position, then all this time, inner water supply system and connected to it domestic equipment (washing and dishwashers) are protected from harmful effect hydraulic impact on the side of the supply mains water supply, and the inner gas supply system and connected to it domestic equipment (gas plate, cooking surface and aerophons cabinets) are protected from pressure surges, thereby, increased working life of the whole the following equipment. Device for automatic control of water supply and gas has connected to electric network at least one safety locking-regulating unit, installed after connection points, on pipeline water supply (gas) in the room, which includes normally-closed solenoid valve provided with electromagnetic coil and line of bypass with ball valve, required for use in cases of absence of voltage on the side of the source of supply or in case of failure of electromagnetic coil, has control unit, which includes automatic switch, step-down transformer voltage and perform time relay with functions of adjusting time, required for switching of electric circuit supply electromagnetic coil of valve, with certain, preliminarily zaprogrammirovannom time, required for operation of domestic appliances (dishwashing and washing machine, gas plate and T. u.), comprises at least one control pickup, made, for example, in the form of motion sensor with function of adjusting time disconnection from 5 seconds to hour and more, during which it will operate from the last moment of human detection, is installed and is adjusted, that least at approaching to of water fittings, man, falls in zone of sensor sensitivity. For prevention of gas supply to place of possible ignition, in control circuit of solenoid valve, safety zapornoreguliruyushchego unit gas system of room, normally-closed contact fire flue of sensor, which operates at appearing in room smoke and by its contact breaks the electric circuit, thereby preventing (prevents) power supply to electromagnetic coil valve. 7 ill.
