Description

The utility model relates to sanitary water supply systems (gas supply) and can be used to prevent flooding of rooms with water fittings and to prevent the formation of explosive and fire hazardous concentration of air-gas mixture in rooms, residential and public buildings, which can ignite and / or explode.

A device for automatically controlling the water supply by emergency shutdown of the water supply, comprising safety valves that are in the closed state in the absence of electric power, is installed on the pipeline for supplying water to the room, electrically connected to the control unit, which ensures its operation when there are signals about leaks from in places of the probable occurrence of water sensors made in a closed design, excluding contact with live contacts, for not preventing the penetration of water to the sensor contacts (lm №71348, IPC E03S 1/00, op.10.03.2008 g).

A device for controlling the gas contamination of a room is known, including a power supply unit, a gas supply sensor, an acoustic and light alarm unit, an external circuit control unit, an automatic gas cut-off unit and a control circuit for this unit, the input of which is connected to the output of the external circuit control unit, and the output to the input block automatically shut off the gas supply, according to the decision, an additional block has been introduced to control the output voltage of the gas pollution sensor, configured to memorize the emergency state and the device operability control lock configured to reset the emergency state, while the output of the gas pollution sensor is connected to the first input of the output voltage control unit, and the device operability control unit is connected to the second input of the output voltage control unit, the output of which is connected to the first input of the sound and light unit alarm and one of the inputs of the external circuit control unit (metro No. 77072, IPC G08B 17/10, October 10, 2008), the task of which is to expand the functionality of the device Gas contamination monitoring facilities and increasing the level of safety during its operation. The technical result achieved by using the inventive utility model is to provide the ability to control the breakage of the gas pollution sensor and the state of the unit for automatically shutting off the gas supply, as well as storing and resetting the emergency condition.

The closest in technical essence to the claimed device is a device for emergency shutdown of the water supply with remote control, containing a supply pipe with water fittings (tap), in front of which is installed safety valves (normally open solenoid valve), a control unit to which a presence sensor is connected water (two open electrodes). The power supply to the control unit is made from two sources: both from a power supply unit operating from an AC 220 V network, and from a rechargeable battery configured to be recharged from a power unit. The sensor electrodes are installed on the floor of the room under the drain hole of the water fittings (tap) or in any other place where water is likely to appear during emergency operation of the system. The sensor is equipped with a radio transmitting device, and the control unit has a radio signal receiver capable of receiving the radio signal of the radio transmitting device (metro No. 74140, IPC E03C 1/00, op.20.06.2008).

The known device eliminates the possibility of electric shock to humans and pets, and in the event of a power failure, the device will work in standalone mode, however, it cannot exclude leaks during an abnormal mode of operation of the water supply network in the case of an open tap or from leaks associated with the tightness of the locking elements in the sewage system, which increases the irrational consumption of water consumed. In addition, during the operation of the water supply network in the normal mode, the shutoff valves are in the open state and the pipeline elements (connections, gaskets, etc.) are constantly exposed to water hammer from the supply water supply network, thereby reducing the operating life of the equipment.

The problem to which the claimed technical solution is directed is to prevent flooding of the premises of residential and public buildings during an abnormal mode of operation of the water supply network, to save the consumption of consumed water in the case of an open water taps and with small leaks associated with leaks of connecting, sealing and other water supply elements, in saving energy consumption, in reducing the harmful effects of water hammer on the connecting and sealing elements of the water supply, in reducing the likelihood that humans and animals will be exposed to the harmful effects of high voltage, reducing the cost of installing equipment, the ability to operate the system offline when the voltage disappears, and the ability to send a signal about leaks to the owner’s mobile phone on time (for example, in the form of an SMS message) and (or) to the central emergency service, in order to prevent the formation of explosive and life-threatening gas-air mixture during abnormal operation of the gas supply system due to e depressurization, such as rupture of a connecting hose, extinction of the flame of nozzles of a gas stove, oven, etc., left unattended for a long period of time, and also in saving gas from small leaks due to leakage of connecting, sealing, shut-off and other elements of the gas pipeline system.

The technical result achieved by using the claimed utility model is to ensure the safe operation of rooms with water-folding (gas-folding) fittings.

The problem is solved as follows. In a device for automatically controlling the flow of water (gas) containing safety shutoff valves, according to the claimed utility model, shutoff valves are made in the form of a normally closed solenoid valve with a manual actuator with an electromagnetic coil of supply voltage - 12 Volts installed on the pipeline for supplying water (gas) into the room, a control panel with an AC voltage converter 220 Volts to DC voltage - 12 Volts with a battery and its recharging function, with a timer, a control unit, a wireless water sensor for timely information about leaks and at least one control sensor that provides safety valves, according to the claimed utility model, each control sensor is made in the form of a wireless motion sensor with autonomous power installed in the room with water folding (gas folding) fittings.

Moreover, each wireless motion sensor can be made in the form of a wireless presence sensor, and each electromagnetic valve with an electromagnetic coil operating voltage of 12 volts can be made in the form of a ball valve with electric drive operating voltage of 12 volts.

In addition, each wireless motion sensor can be made in the form of a timer.

When controlling a normally closed solenoid valve in the form of a ball valve with an electric actuator installed on the pipeline for supplying water (gas) to the room, wireless presence sensors in the form of wireless motion sensors, etc., water (gas) is always supplied to the water-folding (gas-folding) fittings in the presence of a person, therefore, in the event of an accident at a water supply system (gas pipeline), or in the case of an open water folding (gas folding) tap, flooding (filling with gas) of premises of residential and public buildings is excluded and irrational consumption of water (gas). In addition, when the water supply network operates in normal mode, the solenoid valve, when closed, protects the water supply system of an apartment, house, building, etc. from a water hammer, and the gas system from a sharp increase in pressure, the coil of the electromagnetic valve or the electric ball valve is not energized and does not consume electricity. Water availability sensors are installed in the most probable accumulation of water resulting from flooding by neighbors from the upper floors or from water leaks from the heating system, for example, in the area where sewer and water pipes pass through the floor floors.

The presence of significant features distinctive from the prototype allows us to recognize the claimed device as new.

The figure schematically shows the inventive device.

Water (gas) is supplied to the room from the riser 1 of the central water supply system (gas pipeline), to the connection point 2. The device for automatically controlling the water and gas supply comprises a manually-controlled solenoid valve 3 connected from the control panel 6 and mounted on the supply pipe water (gas) into the room after the connection point 2, equipped with an electromagnetic coil 4, and control sensors, made, for example, in the form of wireless motion sensors 5, installed in rooms with water gas (gas-folding) fittings (water mixer, drain tank, shower or gas stove, oven, etc. in an apartment, office, hotel, etc.) installed and configured in such a way that they work only when a person approaches water folding (gas folding) fittings. Wireless motion sensors 5 have a setting of the time interval for shutdown, during which they will work from the moment of the last detection of movement (presence) of a person from 2 seconds to an hour. If there are several points with water-folding (gas-folding) fittings, a wireless motion sensor 5 is installed at each of these points. When a person crosses the detection zone, the radio signal from the wireless motion sensor is fed to the control panel 6, which, in accordance with the specified operation algorithm, generates a response signal coils 4 of the electromagnetic valve 3. On the timer of the control control panel 6, the time required for the formation of an electrical signal to turn on for prison coil 4 of the electromagnetic valve 3, the duration of the appliances (washing machine and dishwasher). If the voltage disappears from the power supply, the device automatically switches to stand-alone power from a backup power source - 12 Volts. The wireless sensor for the presence of water 7 notifies the landlord of leaks by means of SMS messages to phone 8 or to the dispatch center of the repair and restoration service.

When controlling a normally closed solenoid valve installed on the pipeline for supplying water (gas) to the room, presence sensors in the form of motion sensors, a timer, etc. water (gas) is supplied to the water-folding (gas-folding) fittings of the kitchen, bathroom, bathroom, etc. always in the presence of a person, therefore, in the event of an accident on the water supply system (gas pipeline) itself, as well as on equipment installed on that water supply system (gas pipeline) or in the case of an open water folding (gas folding) tap, flooding and filling with gas of premises of residential and public buildings and irrational water consumption are excluded ( gas). In addition, when the water supply network operates in the normal mode, while closed, the electromagnetic valve is not energized, does not consume electricity and prevents the internal water supply system from water hammer, and the gas supply system from sudden changes in gas pressure.

When the water supply (gas pipeline) network is in normal operation, the shutoff valves are in the closed state: the coil 4 of the electromagnetic valve 3 is not energized and the valve 3 is closed. When a person crosses the range of motion sensor 5, the sensor is triggered, a signal is generated by means of radio communication to supply voltage to the coil 4 of the electromagnetic valve 3, the coil solenoid is pulled and opens the electromagnetic valve 3, providing water (gas) to the water-folding (gas-folding) valve. When a person is removed after the set response time has elapsed, the sensor 5 breaks the electric circuit to control the electromagnetic coil 4 of valve 3, and valve 3 closes, blocking the water supply.

It is recommended that safety shutoff valves be installed on the riser for supplying water (gas) to the room, and in the case of a small house, on the pipeline for introducing water (gas) into the building.

If cold and hot water is supplied to the room, two electromagnetic normally closed valves can be installed, one for each system.
