Description

The invention relates to mechanical engineering, in particular to systems for shutting off the fluid supply when a leak is detected, and also to a method for shutting off the fluid supply. The proposed system and method have significant advantages when used to shut off the fluid supply in the water and heating networks of residential, public and industrial premises, but their use is not limited to this, and they can be used in various networks and pipelines for transporting any liquid. The proposed system can be installed at any facility, for example, where there is a water supply system. Moreover, it is especially effective to install the proposed system in rooms where a large amount of equipment is located and there is a wide branched electrical network, for example, in a data center, banking organization or server, where leakage poses a serious threat not only to the functioning of the entire system, but also for the safety of staff.

State of the art

There are well-known sanitary-technical water supply systems for residential and public buildings, including a pressure head water supply pipeline with an extensive network of individual water consumers (washbasins, showers, etc.) equipped with water-folding fittings (Isaev V.N. et al. technical systems of buildings. - M.: Higher School, 1984, pp. 175-176, Fig. 98).

A disadvantage of the known systems is the possibility of flooding with water from the water supply network through the water fittings, since the specified valves are not equipped with devices for emergency shutdown of the water supply during abnormal operating modes of the water supply network, namely, when the water supply is discharged, the water is re-fed after a break, when left open taps, in the event of a pressure surge in the network, in case of failure of the water fittings, in the event of leaks due to defects in the water fittings or piping odov or due to poor installation water fittings or other elements of the water supply network.

There is also known a system for detecting water leaks and shutting off its supply in the room (RF patent for the invention No. 2307898, IPC E03C 1/00, Ρ24Ό 19/10), containing electromagnetic shut-off valves, moisture-sensitive sensors, control device, electrically connected as with electromagnetic valves, as with moisture-sensitive sensors, and a power supply unit connected through an input to a 220 V electric power source, the control unit comprising a switching unit and an indication unit to which a power supply unit is connected.

A disadvantage of the known system is the dependence of the system on an external power source, because the power supply must be connected to an electric current network with a voltage of 220 V. With this disadvantage of the known system is associated with insufficient reliability of the system, because leakage and flooding of the room can lead to other emergency situations, characterized, for example, by a blackout in the power supply network. In addition, in the case where the power is turned off, the known system also cannot work properly and prevent flooding.

Another disadvantage of the known system is the complexity of the installation due to the need to connect the elements of the system with each other and with the mains via connecting wires. In addition, rupture of the connecting wires in any area leads to the inoperability of the entire system during leakage, which reduces the reliability of the system.

In addition, there is a known mechanical system for controlling and preventing water leakage (Eurasian patent No. 200901009, IPC E03C 1/00, Ρ17Ό 5/02), comprising a controller in the form of a spring, a water supply lock device in the form of a cable with a lock, a water leakage sensor containing tape.

In this invention there are no elements that require electricity for their operation. However, this system has disadvantages, such as the need to replace the tape, each time after the system is triggered, the absence of leakage warning elements. In addition, the water leakage sensor containing the tape and connected to the ball valve by means of a cable, obviously, cannot be located at a sufficient distance from the valve. In addition, in the event of an unintentional bending of the cable, for example, by the user, a false operation of the system and blocking the water supply are possible.

In addition, it is also known a device for emergency shutdown of water OGOGOOSK (RF application for invention No. 2007128196, IPC E03C 1/00), which is the closest analogue and contains a detecting unit for moisture detection, a shut-off valve, a control unit for controlling the shut-off valve associated with indicated by at least one detection unit and at least one shutoff valve. The detection unit is made in the form of a fluid sensor. The control unit is configured to provide a signal during emergency operation, and the shut-off valve consists of a ball valve and an associated electric actuator and is electrically connected to the liquid presence sensor through the control unit.

A disadvantage of the known device is the need to use an actuator associated with a shutoff valve when closing this shutoff valve, which increases the power consumption of the system. Moreover, the actuator automatically or upon receipt of a signal from the control unit 1,023121 periodically performs full or partial closure and opening of the water supply or other liquid to prevent damage to the shutoff valves due to the formation on the internal parts of the shutoff valve of extraneous deposits of substances contained in water or other liquids. The specified operating mode of the electric drive is necessary to prevent souring of valves. In the event that such souring has occurred, the device for emergency shutdown of water may not work or when the device is triggered, the valves may be damaged, which leads to insufficient reliability of the system. Due to the need for periodic actuation of the electric drive in a known device, the cost of electricity is further increased. In addition, the known device is a complex and expensive system.

Thus, despite the popularity of various systems for emergency shutdown of the liquid, the need for simpler and more reliable systems for shutting off the fluid supply with reduced power consumption is obvious.

SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION

In FIG. 1, an example is a diagram of a system 100 for shutting off a fluid supply, comprising a shut-off valve 10, a control unit 20, a detection unit 30, and a warning unit 40. The shut-off valve 10 is installed in an easily accessible portion of the pipe 50 through which the fluid is transported, so that when the shut-off valve 10 is closed, liquid leakage and, consequently, flooding of the room are prevented. Preferably, the shut-off valve 10 and the control unit 20 are formed in one housing. The detection unit 30 is located in a place where it is suspected that there will be fluid in the event of a leak in the fluid transport system, for example, in the bathroom, toilet, kitchen on the floor or wall, under sinks, wash basins, near radiators and

- 4 023121

etc. In case of leak detection, the detection unit 30 transmits the first information signal K81 to the control unit 20. Upon receipt of the first information signal supplied by the detection unit 30, the control unit 20 supplies a control signal to the shutoff valve 10 to close it. In addition, in case of leak detection, the detection unit 30 transmits a second information signal K82 to the warning unit 40. Upon receipt of the second information signal supplied by the detection unit 30, the warning unit 40 provides an indication of the closure of the shut-off valve 10 by means of an audible and / or light signal. In addition, the indication may be provided in any known manner. The warning unit 40 may be located away from the shutoff valve 10, for example in living rooms when using the system 100 in apartments or in rooms in which people are located, in the case of using the system 100 in public and industrial premises. The warning unit 40 is placed near the premises where people are supposedly located to provide prompt notification of the closure of valve 10, and accordingly of the closure of the pipeline 50. After the notification, it is assumed that action is necessary to eliminate the causes of the appearance of liquid and then it is necessary to open the shutoff valve 10 to restoring the movement of fluid flow in the conveying system.

System 100 may include, in addition to existing blocks, additional detecting and / or notification blocks (not shown in the diagram). Such an embodiment of the invention can be used, for example, when placing one shut-off valve on a common pipeline, which further branches into sections, and possible leaks can be detected by detection blocks independently from each other in the areas near which they are located. Upon receipt of an information signal from any of the detecting units, the control unit transmits a control signal to the shutoff valve to close it. Each detection unit can be associated with several warning units, which can be located in different rooms, as well as all detection units can be associated with one warning unit. Thus, by placing each detection unit in place of the alleged leak, it is possible to control the occurrence of leak in a larger area. Such a system can be used, for example, in an apartment or house, which have a large area.

In FIG. 2, an example is a diagram of a system 200 for shutting off a fluid supply, which comprises two shutoff valves 10, 11, control blocks 20, 21, detection blocks 30, 31, and warning blocks 40, 41. Valves 10 and 11 are shown mounted on a common pipeline 50 but can be installed on different pipelines. The shutoff valves 10, 11 are connected to the corresponding control units 20, 21. Block 20 is configured to receive a first information signal K81 supplied by the corresponding detection unit 30, block 21 is configured to receive a first information signal K.811 supplied by the corresponding detection unit 31. The notification unit 40 is configured to receive a second information signal K82 supplied by the corresponding detection unit 30, the notification unit 41 is configured to teachings of the second information signal K.821, supplied by the corresponding detecting unit 31. Block 20 is configured to supply a control signal to the corresponding valve 10 to close it, block 21 is configured to supply a control signal to the corresponding valve 11 to close it. A feature of the invention is that when transmitting a radio signal, various detection units use different codes, which ensures that only the corresponding valve is closed. Thus, the influence of the detecting unit on an inappropriate shutoff valve is excluded, for example, when a leak is detected by the detecting unit 31, the shutoff valve 11 will be closed, and the valve 11 will be closed by the block 41, and the valve 10 will remain in the open position and the warning block 40 will not give a warning signal until a leak is detected by block 30. A system similar to system 200 can be used, for example, in an apartment building, because identical devices (for example, valves, units) can operate without mutual influence in a limited area. The diagram shows a system 200 containing two shutoff valves, and it is obvious that it can contain more than two shutoff valves, each of which can be associated with a corresponding control unit, each control unit can be associated with at least one corresponding detection unit, and each detecting unit may be associated with at least one corresponding notification unit.

As an example, a system can be given to turn off the liquid supply in the water supply or heating system of an apartment building in which at least one shut-off valve with a control unit can be installed on the pipeline, which can be accessed from the entrance, and in each apartment on the pipelines additional shutoff valves are installed with corresponding additional control units; at the presumptive, probable place of the leakage of the pipeline associated with the corresponding shutoff valve, the corresponding detection blocks are located. In the event of an emergency, such a branched system makes it possible to detect leaks and turn off the fluid supply to the corresponding section of the pipeline in which the leaks are detected and thus prevent flooding. In addition, in the system for an apartment building, each detection unit is associated with a corresponding notification unit, and in the event of a liquid outage, the place of occurrence of the leak can be quickly found, and the cause of the leak can be quickly eliminated.

In the above example, when a leak is detected, the detection unit provides a first information signal to the corresponding control unit and a second information signal to the corresponding notification unit, wherein said first information signal of the detection unit causes the control signal to be supplied by a specific control unit associated with said detection unit to a specific shut-off valve to shut off the fluid supply, and the second information signal activates the corresponding nth specific alarm unit. Thus, in the event of a leak, the shut-off valve connected to the portion of the pipeline on which the leak is detected is activated and the corresponding notification unit shows by indicating where the leak has occurred, the shut-off valves and the warning units located in other sections are not actuated by signal supply to an unrelated detection unit, thereby the specified system is protected from false alarms of shut-off valves installed on in different sections of the pipeline, and activation of the warning blocks, correlating with open shut-off valves in serviceable areas through the corresponding detection blocks.

In FIG. 3 is a functional diagram of an exemplary detection unit 30. The detection unit 30 includes a moisture sensor 32, a microcontroller 33, a radio transmitter 34, a sound emitter 35, an antenna 36, and a power supply 37. The moisture sensor 32 is based on the principle of electrical conductivity of the liquid. When the conductivity between the contacts of the moisture sensor 32 reaches a certain predetermined value, the microcontroller 33 exits the standby mode, turns on the sound emitter 35 and transmits a signal containing a certain code sequence to the radio transmitter 34. The radio transmitter 34 transmits the first informative radio signal to the control unit and the second informing radio signal to the detector unit. The radio transmitter transmits the signal for a short time, then pauses and resumes the transmission of the signal for a short time, so that it makes it possible to work with other devices using this radio frequency. Preferably, the radio signal has a frequency in the range of 433 MHz, in the so-called LPR band, in which 69 channels are allocated for wearable radio stations with a transmitter output power of not more than 0.01 watts. Power to all elements of the detecting unit 30 is provided from an autonomous power supply element 37. The detection unit consumes energy when detecting leaks and transmitting signals. In standby mode, the detection unit has extremely low power consumption.

Moreover, in the inventive system, autonomous power elements, for example, primary chemical current sources of type AA, are preferably used for powering all the system units, and due to the system design, in which the system units consume extremely little energy in standby mode, the service life of the power elements before replacement is at least 10 years. In addition, due to the design of the system, the relative duration of the standby mode is increased in comparison with other modes, and accordingly, in general, the overall power consumption of the system is reduced. In addition, the invention is not limited to the use of primary chemical current sources of any type and type, for example, carbon-zinc, alkaline, lithium, etc., otherwise called galvanic cells, it is also possible to use secondary chemical current sources, otherwise called electric batteries, for example nickel-zinc (ΝίΖη), nickel-metal hydride (ΝίΜΗ), nickel-cadmium (ΝίΟά), etc.

In FIG. 9 shows the appearance of the detection unit 30. The detection unit 30 is small in size, which can be estimated by comparison with the known lighter shown. Thus, the detection unit 30 can be located in a small space, for example, under a bathtub or near water pipes.

In FIG. 10 shows the appearance of the detection unit 30 in the open position. In the housing of the detecting unit 30, the main part of the space is occupied by power supply elements 37, which determine the overall dimensions of the detecting unit 30.

In FIG. 8 shows the appearance of the notification unit 40, for comparison of the overall dimensions of which a lighter is additionally shown. Due to its small size, the notification unit 40 can be located in any convenient place in the room, for example, inside a cabinet, on a shelf, etc.

Due to the fact that the detection unit 30 is connected to the control unit and / or the notification unit via a radio channel, and the power of the detection unit, the control unit, and the notification unit is provided by autonomous power elements, the installation of the system is simple due to the absence of wires connecting the units to each other and to the supply network, and the blocks can be easily transferred to a new place and the reliability of each block, unlike the known devices, is independent of external factors, such as reliability with single wires and mains supply.

Additionally, the system for shutting off the fluid supply may include a remote control. The remote control unit is configured to transmit a third information signal to the control unit. Upon receipt of the specified third information signal, the control unit provides a control signal to the shutoff valve to close it. Thus, when using a system containing a remote control, the user can put the shut-off valve in the closed position at his discretion. The user can use such a system when he intends to leave the room or assumes his long absence, for example, intends to go on vacation, while the user puts the valve in the closed position in advance and thereby prevents leakage of liquid, flooding of the room and the indication of the closing of the shut-off valve by the warning unit. Thus, the user has a choice and, at his discretion, he can use the remote control to put the shut-off valve in the closed position or leave it open. In the latter case, the valve will be moved to the closed position automatically by the system in case a leak is detected by the detection unit.

In addition, the system for shutting off the fluid supply may further comprise an OZM module. The specified OZM module is configured to transmit and receive 8M8 messages. The user has the opportunity to send an ZMZ message, for example, via a mobile phone or the Internet to an OZM module. Upon receipt of a message from the user, the OZM module transmits a fourth information signal to the control unit, which in turn transmits the control signal to the shutoff valve to close it. Thus, the user has the opportunity at his discretion to translate the shut-off valve into the closed position.

In addition, in case of leak detection, the detection unit is configured to transmit a fifth informative signal to the OZM module, which in turn sends the user an ZMZ message about the leak detection by the detection unit and closing of the shutoff valve. Thus, the user is remotely informed of leaking and closing the shut-off valve and has the ability to quickly take the necessary measures. In the case of using the OZM module in the system, in addition to the above examples, other options for the interaction of the system units and the user are possible, which are obvious to a person skilled in the art.

In addition, the system for shutting off the fluid supply may further comprise a pumping device (not shown). The specified pumping device containing the pump, is configured to pump the liquid upon receipt of the sixth information signal from the detection unit. Such a pumping device may be located, for example, in the basement. The system containing the pumping device additionally prevents the flooding of the room in cases where there was an accumulation of liquid before the shut-off valve overlapped or in cases where the shut-off valve did not occur, or a leak occurred in a place in the pipeline that cannot be blocked by the shut-off valve.

Said first, second, third, fourth, fifth and / or sixth information signals are preferably radio signals transmitted over a radio channel in the range of 433 MHz.

In FIG. 4 is a cross-sectional view of an overhead valve 10 according to one embodiment of the invention. The shut-off valve 10 contains a magnetic device made in the form of an inductor 5, and a trigger device made in the form of a rod 1. The shut-off valve 10 also contains a storage device made in the form of a spring 3, a return device 4, a locking device made in the form of a rod 2 having a locking part 6. On the base of the rod 2 is fixed heel 8 with a rubber sealing ring (not shown). In FIG. 4, the shutoff valve 10 is shown in the open position, also called the original position. The direction of fluid flow is indicated by an arrow. In the open position of the valve 10, the rod 2 is in the initial position, which is held by the rod 1 through the locking part 6. In this case, the storage device is in the state with the accumulated potential energy, in this embodiment, the spring 3 is in a compressed state, i.e. . in a state with accumulated potential energy. When the shut-off valve 10 is in the open position, energy is not required. The transition of the valve 10 from open to closed occurs when the valve 10 receives a control signal supplied by the control unit. The control signal is a short-term electrical signal transmitted to the inductor 5. Under the action of the electromagnetic forces of the coil 5, the rod 1 moves in such a way that it releases the rod and the compressed spring 3. Since the potential energy tends to zero, the spring 3 unclenches and performs the work of moving the rod 2 to its final position due to previously accumulated energy. The accumulated energy is consumed in a short time, which allows the spring to develop more power to move the rod 2. When the rod 2 moves to the final position, the heel 8 moves with it and closes the passage opening 7 with the liquid supply shut off. Rubber

- 7 023121 ring seals the floor. Thus, the closing of the shut-off valve occurs automatically when the control unit supplies the control signal to the shut-off valve.

When the control unit delivers a control electric signal to the inductance coil of the shut-off valve, electromagnetic forces acted upon by the coil act on the trigger, the forces trigger the trigger, which releases the shut-off device, and it is unlocked and activated by the energy stored in the accumulator device. Thus, the energy required to actuate the locking device is communicated, for example by the user, in advance upon completion of work and is accumulated in the storage element, i.e. to actuate the locking device does not require electricity. To actuate the trigger device, which is the initiator to actuate the shut-off device, electric power is required to supply a short electrical pulse to the inductor. Since the energy-intensive work of closing the shut-off valve is carried out due to the energy received in the process of the preliminary perfect work of opening the valve, and the electric power necessary only to perform the initiating actuation of the trigger device, as a result of which the shut-off device is released, is small, the energy consumption for functioning such a valve is small and can be provided with autonomous power elements, for example, primary or secondary chemical sources current sources. Thus, the closing of the shut-off valve occurs automatically, and the opening of the valve occurs as a result of mechanical work.

To move the valve from open to closed, electric power is required, which the control unit receives from the power supply elements of the control unit and consumes to supply a control signal. For fixing the shut-off valve 10 in the closed position, energy is not required, since the heel 8 hermetically closes the hole 7 by the action of the spring 3.

To open the shutoff valve 10 by means of a returning device 4, the rod 2 is returned to its original position. Due to the work performed in the process of returning the rod 2 to its original position, the storage device, for example, the spring 3 accumulates enough energy to close the shut-off valve 10 in the future. To fix the rod 2 in the initial position, act on the rod 1 to ensure fixation through the locking part 6 of the rod 2 in the initial position, at the same time an electronic setting of the state of the openly closing valve 10 is implemented in the control unit. Such an effect on the rod 1 can be carried out, for example, by pressing a button on the control unit, or in any other way that allows you to lock the locking device 2 through the trigger device.

In FIG. 5 is a cross-sectional view of an overhead valve 10 according to one embodiment of the invention. The shutoff valve 10 is shown in the open position, also called the original. The direction of fluid flow is indicated by an arrow. Elements having the same purpose are denoted by the same numbers as the elements described in the previous embodiment shown in FIG. 4. The gate 6, rigidly connected with the rod 2, performs the function of a stopper. The transition of the valve 10 from open to closed occurs when the valve 10 receives a control signal supplied by the control unit. The control signal is an electrical signal transmitted to the inductor 5. Under the action of the electromagnetic forces of the coil 5, the trigger device, made in the form of a rod 1, moves in such a way that it releases the knob 6. Under the action of the rotation spring 17 and due to the energy accumulated by it, the knob 6 and the rod 2 connected with it rotate 90 around the stem axis degrees, and the ball valve mechanism, rigidly connected to the stem 2, shuts off the fluid supply. To find the shut-off valve 10 in the closed or open positions, energy is not required. To transfer the shut-off valve from the open position to the closed control unit, it consumes the electric power received from its power supply elements to supply a control signal to the shut-off valve 10.

To open the shut-off valve 10, it is necessary to return the device, for example, the handle 4, by 90 ° in the direction opposite to the direction of rotation of the valve 6 and rod 2 in order to return them to their original position. Due to the work done in the process of returning the rod 2 to its original position, the spring 17 accumulates enough energy to close the shut-off valve 10 in the future. To fix the rod 2 in the initial position, they act on the rod 1 in such a way that they fix the rod 2 through the valve 6 in the initial position, while the control unit implements an electronic setting of the state of the openly closing valve 10.

In FIG. 6 is a cross-sectional view of an overhead valve 10 according to one embodiment of the invention. The shutoff valve 10 is shown in the open position. The direction of fluid flow is indicated by an arrow. Elements having the same purpose are denoted by the same numbers as the elements described in the embodiment shown in FIG. 4. The shutoff valve 10 comprises a spring-loaded lock 9 fixed to the axis 12. The valve 10 moves from the open position to the closed position when the valve 10 receives a control signal supplied by the control unit. The control signal is an electrical signal transmitted to the inductor 5. Under the action of the electromagnetic forces of the coil 5, the trigger device 8 023121, made in the form of a rod 1, is actuated and interacts with the latch 9, for example, strikes the end of the latch 9. The latch 9 rotates on the axis 12 and is released from engagement with the locking part 6 rod 2. The spring 3 is unclenched and does the work of moving the rod 2 to the final position due to previously accumulated energy. The accumulated energy is consumed in a short time, which allows the spring 3 to develop more power to move the rod 2 and, accordingly, shut off the fluid supply. As in previous embodiments, for transferring the shut-off valve 10 from an open position to a closed position, the control unit consumes electricity received from its power supply elements to supply a control signal to the shut-off valve. To find the shut-off valve 10 in the closed or open positions, energy is not required.

To open the shut-off valve 10, it is necessary to pull the return device, for example, the handle 4, so that the rod 2 is in its original position. To fix the rod 2 in the initial position, they act on the rod 1 in such a way that it returns to its original state, while the spring-loaded clamp 9 returns to its original position, in which it fixes the rod 2, and in the control unit an electronic setting of the state of openly overlapping valve 10.

In FIG. 7 is a sectional view of an overhead valve 10 according to one embodiment of the invention. The shutoff valve 10 contains an accumulating device made in the form of a mechanical recuperator 13, a magnetic device containing an external coupling half of a magnetic coupling 14 and a trigger device containing an internal coupling half of a magnetic coupling 14, a nut 15 and a screw 16 as a locking device, on the base of which a pin 8 is fixed The shutoff valve 10 is shown in the open position. The direction of fluid flow is indicated by an arrow. The transition of the valve 10 from the open position to the closed position occurs when the valve 10 receives a control signal supplied by the control unit. The control signal is an electric pulse transmitted to the magnetic coupling 14. Upon receipt of the control signal, the external coupling half of the magnetic coupling 14 is closed and the trigger device containing the internal coupling half of the magnetic coupling 14 is actuated. Due to the energy previously accumulated and stored in the recuperator 13, the screw 16 rotates in a rigidly fixed nut 15, switches to the final position, closes the passage hole 7 and, accordingly, blocks the fluid supply.

When the shut-off valve 10 is opened, the work performed when lifting the screw 16 is converted into energy, in this example, the energy of rotation of the flywheel and is accumulated in the mechanical recuperator 13.

In addition, in any of the above embodiments of the shut-off valve, the accumulation of kinetic energy of the liquid and / or thermal energy of the liquid can additionally be used.

In an embodiment in which the thermal energy of the liquid is used, the shutoff valve 10 further comprises at least one thermoelectric transducer, for example a Peltier element, and the shutoff valve storage device comprises at least one charge storage device. The specified device for the accumulation of charge is made, for example, in the form of a capacitor or supercapacitor. The thermal energy of a liquid is converted by a thermoelectric converter into electrical energy, which is stored in a charge storage device. The accumulated electrical energy is used to actuate the trigger device by transmitting this energy to the magnetic system of the shutoff valve.

In an embodiment in which the kinetic energy of the liquid is used, the shutoff valve 10 further comprises at least one turbine, and the shutoff valve storage device comprises at least one charge storage device. The specified device for the accumulation of charge is made, for example, in the form of a capacitor or supercapacitor. The kinetic energy of a liquid is converted by a turbine into electrical energy, which is stored in a charge storage device. The accumulated electrical energy is used to actuate the trigger device by transmitting this energy to the magnetic system of the shutoff valve.

Thus, the energy required to close the shut-off valve can be fully accumulated in the shut-off valve. In this case, the energy necessary for actuating the descent device comes from the charge storage device, and the energy necessary for moving the shut-off device from its initial position to its final position is accumulated when the shut-off valve is opened and is supplied by the spring of the storage device.

In addition, the shutoff valve 10 can be implemented with the possibility of using the kinetic and / or thermal energy of the liquid to open the valve. In this case, the shut-off valve contains at least two independent devices for accumulating charge, and the return device of the shut-off valve contains at least one inductor. One of

- 9,023,121 of said charge storage devices associated with the magnetic device supplies electrical energy to the magnetic device to actuate the release device. A second charge storage device associated with the return device supplies electrical energy to the inductance coil of the return device. By means of electromagnetic forces imparted by the inductor, the shut-off device is returned to its original position, and the shut-off valve is opened and energy is accumulated in the spring of the storage device. Thus, for example, the electrical energy stored in the capacitor can be converted to the potential energy of the spring by opening the shut-off valve. To fix the locking device, by means of the cocking of the trigger device, the electric energy stored in one of the charge storage devices can also be used. In this case, the magnetic device receives electrical energy from the device for storing charge, and by means of magnetic forces imparted by the magnetic device, the trigger device is returned to its original position.

Thus, in the proposed shut-off valve, the following principle of action is implemented: in the process of opening the valve, the shut-off device is reset to the initial position, in which the energy spent on the work is accumulated by the accumulating device, the trigger device is cocked to fix the shut-off device in the initial position. When the shut-off valve is in the open position, the shut-off device and the release device are in their respective initial positions, while the energy stored in the storage element has a maximum value. The open position of the valve is stable, energy is not required to find the valve in the open position, and work is required to move the valve from the open position. When the control valve receives the control signal supplied by the control unit under the action of electromagnetic forces imparted by the inductor, the trigger device is actuated and at the same time releases the locking device and the accumulating device, which brings the locking device out of its original position. In this process, the energy accumulated by the storage element is used to move the shut-off device to the closed position, in which the shut-off valve, respectively, is in the closed position. The closed position of the valve is characterized by the minimum value of potential energy and is stable, it does not require energy consumption to find the valve in the closed position, and work is required to move the valve from the closed position. To open the valve, work is done and the cycle starts again. In this case, the work for opening the valve can be performed, for example, by the user. In other embodiments, the operation for opening the valve is due to electric energy stored in the charge storage device.

Thus, in all the above examples of the implementation of the shut-off valve, the principle is implemented, which includes the accumulation and conservation of energy generated by the work when opening the valve, and the ability to quickly release the accumulated energy due to a short electrical pulse. In addition, the kinetic and / or thermal energy of the fluid can be used to operate the shutoff valve.

As the storage device, various known materials and elements can be used, for example, natural and synthetic materials with sufficient elasticity and capable of storing potential energy, for example compression springs, torsion, spiral, rubber, steel strips, wood, woven and fibrous materials, and electrical, mechanical, hydraulic energy recuperators, various devices for thermal and chemical energy storage, etc.

As triggers, rods, clamps, triggers, rods, electrical closures, half-couplings of magnetic couplings, strikers, valves, etc., depending on the type of energy storage device, can be used.

As locking devices can be used rods, screws, etc.

The shutoff valve may be in the form of a check valve or a rotary valve.

The system for shutting off the fluid supply is designed for repeated use and does not require the replacement of any elements after its operation. The system is powered from autonomous power supply elements, and communication between all its units occurs over the air via radio signals.
