[0051] The following reference Figures 1 to 10 Provide a detailed description.

[0052] (Example 1-1) The present invention relates to a flow control valve, which includes: an opening and closing part 100, which is arranged inside a flow path to selectively allow fluid to pass through; and a driving part 200, which is coupled to the opening and closing part 100 to control the position of the opening and closing part 100 on the flow path.

[0053] (Example 1-2) The present invention relates to a flow control valve. In Example 1-1, the driving part 200 is formed into a structure selectively coupled to the upper end of the opening and closing part 100.

[0054] Generally, a valve refers to a device with a movable mechanism that can open or close a channel to allow, block or control the passage of fluid. That is, a valve can be set in the middle of a pipe that serves as a moving channel for fluids such as water, oil, and gas to control the amount, flow direction, and pressure of the fluid.

[0055] Valves are divided into several categories based on their purpose and structural form, including: stop valves, which are usually used as fluid blocking devices, such as faucets; rotary valves, which use disc-shaped valves to control flow; check valves, which control fluid flow in only one direction; pressure reducing valves, which can control and maintain fluid pressure; and plug valves, which control gas blocking and gas direction, such as gas plug valves.

[0056] The present invention is also configured as a structure disposed within a fluid flow path, and is a device for controlling the flow rate and pressure of the fluid passing through the path. To achieve this function, the present invention comprises an opening / closing unit 100 that selectively opens and closes the interior of the path, and a driving unit 200 that controls the position of the opening / closing unit 100 within the path.

[0057] At this time, the driving unit 200 can be formed into a structure selectively coupled to the opening and closing unit 100 provided on the flow path. That is, the driving unit 200 can be formed into a structure detachable from the opening and closing unit 100, thereby ensuring ease of maintenance operation by the administrator during maintenance.

[0058] (Example 1-3) The present invention relates to a flow control valve. In Example 1-2, the driving part 200 includes a coupling hole 201 that communicates with the interior from the lower end.

[0059] (Example 1-4) The present invention relates to a flow control valve. In Example 1-3, the opening and closing portion 100 includes a coupling shaft selectively inserted into the inner circumference of the coupling hole 201.

[0060] The drive unit 200 can be configured to selectively engage with the opening / closing unit 100. In this case, since the drive unit 200 is coupled to the upper end of the opening / closing unit 100, the direction in which the flow path is blocked by the structure that substantially opens and closes the flow path can be aligned with the direction of gravity. With this configuration, even if the coupling between the opening / closing unit 100 and the drive unit 200 is accidentally released, the flow path remains closed, thus preventing potential safety incidents.

[0061] To achieve the above structure, the driving unit 200 may be formed into a structure including a coupling hole 201 formed at the lower end thereof and communicating with the interior. That is, the upper end of the structure for selectively blocking the flow path in the opening and closing unit 100 is selectively inserted into the coupling hole 201, thereby forming a coupling structure between the opening and closing unit 100 and the driving unit 200.

[0062] (Example 2-1) The present invention relates to a flow control valve. In Example 1-1, the opening and closing part 100 includes: a lifting part 110, which is arranged inside the flow path to selectively allow the fluid to pass through; and a shell 120, which accommodates the lifting part 110 inside and is connected to the inlet pipe 1 on one side and to the outlet pipe 2 on the other side.

[0063] The opening and closing unit 100 is provided on a flow path where a fluid flows and selectively opens and closes the flow path.

[0064] Therefore, the opening and closing part 100 includes: a lifting part 110, which is arranged inside the flow path and is coupled to the driving part 200 to rise or fall to a predetermined height; and a shell 120, which is coupled to the flow path with an inlet pipe 1 and an outlet pipe 2 formed at both ends in the longitudinal direction.

[0065] At this time, the lifting part 110 may be provided inside the housing 120 to selectively open and close the flow path formed inside the housing 120 .

[0066] (Example 2-2) The present invention relates to a flow control valve. In Example 2-1, the shell 120 includes a first shell 121, and the first shell 121 includes: a first inlet 121-1 formed at one end in the longitudinal direction of the shell 120 and connected to the inlet pipe 1; and a first outlet 121-2 formed at the lower part.

[0067] (Example 2-3) The present invention relates to a flow control valve. In Example 2-2, the lifting portion 110 is arranged at the inner upper end portion of the first shell 121 and is formed into a structure arranged opposite to the first flow outlet 121-2.

[0068] (Example 2-4) The present invention relates to a flow control valve. In Example 2-3, the shell 120 includes: a second inlet 122-1 formed at the upper part and connected to the first outlet 121-2; and a second outlet 122-2 formed at the other end in the longitudinal direction of the shell 120 and coupled to the outlet pipe 2.

[0069] The housing 120 accommodates the lifting portion 110 therein so as to selectively open and close the flow path formed therein. The housing 120 may include a first housing 121 receiving fluid from the inflow pipe 1 and a second housing 122 discharging fluid to the outflow pipe 2.

[0070] The first housing 121, which receives fluid from the inflow pipe 1, may include a first inlet 121-1 coupled to the inflow pipe 1 at one end and a first outlet 121-2 for discharging the fluid to a lower end. Since the lifting portion 110 is disposed at the upper end opposite the first outlet 121-2, the fluid can be selectively controlled to be discharged toward the first outlet 121-2.

[0071] The second housing 122 discharging the fluid to the outflow pipe 2 may include a second inflow port 122 - 1 receiving the fluid from an upper end portion and a second outflow port 122 - 2 coupled to the outflow pipe 2 at the other end portion.

[0072] That is, when the lifting part 110 descends a predetermined height to close the first outlet 121-2, the fluid does not flow into the second housing 122 through the second inlet 122-1. Therefore, the fluid is not supplied to the outlet pipe 2, so that the corresponding flow path can be closed.

[0073] (Example 2-5) The present invention relates to a flow control valve. In Example 2-1, the lifting part 110 includes: an opening and closing member 111, which is selectively arranged in the path of the fluid to control the flow rate passing through; a rotating shaft 112, which receives power from the driving part 200 to determine the phase value of the opening and closing member 111; and a guide 113, which is combined with the opening and closing member 111 at the lower end and has the rotating shaft 112 arranged on the inner periphery.

[0074] (Example 2-6) The present invention relates to a flow control valve. In Example 2-5, the rotating shaft 112 includes a rotation force transmission device 112 - 1 extending from the outer periphery and contacting the inner periphery of the guide member 113 .

[0075] The lifting part 110 is configured to selectively open and close a flow path formed between the inflow pipe 1 and the outflow pipe 2 , and achieves the above-mentioned technique by power provided by the driving part 200 .

[0076] The lifting unit 110 may be formed into a structure including an opening and closing member 111 that selectively blocks the flow path formed inside the housing 120, a rotating shaft 112 whose upper end is coupled to the driving unit 200 and rotates, and a guide 113 that guides the rising and falling path of the opening and closing member 111. In this case, the lower end of the rotating shaft 112 may include a rotation force transmission device 112-1 that extends from the outer periphery and transmits the rotational force to the opening and closing member 111.

[0077] That is, the rotational force transmitting device 112 - 1 transmits the rotational force provided by the driving portion 200 to the opening and closing member 111 to determine the phase of the opening and closing member 111 on the corresponding flow path.

[0078] (Example 2-7) The present invention relates to a flow control valve. In Example 2-6, the outer periphery of the rotational force transmission device 112-1 and the inner periphery of the opening and closing member 111 include a plurality of thread crests and thread roots having a predetermined pitch.

[0079] (Example 2-8) The present invention relates to a flow control valve. In Example 2-6, the outer peripheral portion of the rotational force transmission device 112-1 and the inner peripheral portion of the guide member 113 include a plurality of thread crests and thread roots with a predetermined pitch.

[0080] The rotational force transmission device 112-1 is configured to extend from the outer periphery of the lower end of the rotating shaft 122, whose upper end is coupled to the driving unit 200 for rotation. Since the outer periphery is formed in a structure that contacts the inner periphery of the opening and closing member 111 or the guide 113, the phase value of the opening and closing member 111 on the corresponding flow path is determined.

[0081] In this case, the outer periphery of the rotational force transmission device 112-1 can be formed to include a plurality of thread crests and thread roots having a predetermined pitch. Since the inner periphery of the opening and closing member 111 or the guide member 113, which contacts the outer periphery of the rotational force transmission device 112-1, is also formed with a plurality of thread crests and thread roots of corresponding shapes, the rotational force of the rotating shaft 122 is converted into an upward or downward force on the opening and closing member 111.

[0082] (Example 3-1) The present invention relates to a flow control valve. In Example 2-1, the driving unit 200 includes: a power unit 210, which receives electricity and controls the position of the lifting unit 110 in the flow path; a control unit 220, which controls the electricity applied to the power unit 210; and a power supply unit 230, which is linked with the power unit 210 and the control unit 220 to supply the electricity required to control the position of the lifting unit 110.

[0083] The drive unit 200 is configured to provide power to the opening and closing unit 100 and control the phase of the elevator 110 provided on the flow path. Specifically, the phase of the opening and closing member 111, which determines whether to open or close the flow path in the elevator 110, is controlled by the rotary shaft 112 coupled to the drive unit 200. This allows the opening and closing member 111 to determine whether to open or close the corresponding flow path. In other words, the drive unit 200 is preferably configured to provide rotational force to the rotary shaft 112.

[0084] In order to be designed into the above structure, the driving part 200 can be formed into a structure including a power part 210 coupled to the lifting part 110 to provide rotational force, a control part 220 that controls the power applied to the power part 210, and a power supply part 230 that selectively applies power to the power part 210.

[0085] (Example 3-2) The present invention relates to a flow control valve. In Example 3-1, the power unit 210 includes a power device 211 that receives electricity from the power supply unit 230 and generates power required to control the position of the lifting unit 110.

[0086] (Example 3-3) The present invention relates to a flow control valve. In Example 3-2, the power device 211 includes a motor that selectively rotates by applied power.

[0087] The power unit 210 is coupled to the upper end of the rotating shaft 112 that transmits power to the opening and closing member 111, so as to transmit the force for raising or lowering the opening and closing member 111 to the lifting unit 110. Therefore, the power unit 210 may be formed into a structure including a power device 211 that rotates the rotating shaft 112 by power applied from the power supply unit 230.

[0088] At this time, due to the structural feature that the rotating shaft 112 receiving power through the power device 211 needs to rotate, the power device 211 is preferably formed as a motor that applies a rotational force to the upper end portion of the rotating shaft 112 .

[0089] (Example 3-4) The present invention relates to a flow control valve. In Example 3-2, the power unit 210 includes a power transmission unit 212 which is coupled to the power device 211 on one side and to the lifting unit 110 on the other side.

[0090] (Example 3-5) The present invention relates to a flow control valve. In Example 3-4, the power transmission part 212 includes a plurality of power transmission gears sandwiched between the power device 211 and the lifting part 110.

[0091] The power device 211 should be formed into a structure capable of applying a rotational force to the upper end portion of the rotating shaft 122 when the power supply unit 230 applies electric power to the power device 211 .

[0092] To achieve the above-described structure, the power unit 210 may include a power transmission unit 212 coupled to the power device 211 on one side and to the upper end of the rotating shaft 122 on the other side. In this case, the power transmission unit 212 is preferably formed as a plurality of power transmission gear structures coupled to the outer circumference of the upper end of the rotating shaft 122 while being coupled to the driven shaft that is ultimately rotated by the applied power.

[0093] (Example 3-6) The present invention relates to a flow control valve. In Example 3-1, the power supply unit 230 includes: a power supply device that continuously receives power from the outside; and a battery that temporarily stores the power supplied from the power supply device.

[0094] The power supply part 230 is configured to selectively apply power to the power part 210 through the control part 220. Therefore, the power supply part 230 may be formed in a structure including a power supply device that receives power from the outside.

[0095] When the power supply device fails to smoothly supply power, it may be impossible to open and close the corresponding flow path. To address this issue, the power supply unit 230 may include a battery to temporarily store the power received by the power supply device. In other words, in an emergency situation where the power supply device fails to supply power, the power stored in the battery can be used to supply power to the power unit 210.

[0096] (Example 4-1) The present invention relates to a flow control valve. In Example 3-1, the control unit 220 includes: a receiving unit 221, which receives a measurement value for controlling the position of the lifting unit 110; a calculating unit 222, which determines whether to open or close the flow path of the lifting unit 110 based on the measurement value transmitted from the receiving unit 221; and a sending unit 223, which sends the value calculated by the calculating unit 222 to the outside.

[0097] The control unit 220 is configured to control the power supplied to the power unit 210. That is, the control unit 220 is formed in a structure that is linked with the power unit 210 and the power supply unit 230 to accordingly control the phase of the lifting unit 110 provided on the flow path.

[0098] At this time, the control unit 220 can be formed into a structure including a receiving unit 221 that receives measurement values ​​based on calculations from other structures, a calculating unit 222 that calculates the lifting height value of the lifting unit 110 based on the measurement values ​​transmitted through the receiving unit 221, and a sending unit 223 that transmits the data calculated by the calculating unit 222 to other structures.

[0099] (Example 4-2) The present invention relates to a flow control valve. In Example 4-1, the receiving unit 221 includes a drive receiving unit 221 - 1 that receives a measurement value of the power supplied from the power supply unit 230 .

[0100] (Example 4-3) The present invention relates to a flow control valve. In Example 4-1, the sending unit 223 includes a driving sending unit 223-1 that sends the value calculated by the calculating unit 222 to the power unit 210.

[0101] The receiving unit 221 is configured to receive the measurement values ​​required by the calculating unit 222 from other structures. In this case, the receiving unit 221 may be configured to receive the voltage and current values ​​of the power supply unit 230. In other words, the receiving unit 221 may include a driving receiving unit 221-1 that is coupled to the power supply unit 230 to receive the measurement values.

[0102] Based on the measured value received from the drive receiving unit 221-1, the calculation unit 222 calculates the phase value of the opening and closing member 111 provided on the flow path. In this case, the transmission unit 223 can be configured to transmit the calculated value to the power unit 210. Specifically, the transmission unit 223 can include a drive transmission unit 223-1 that works in conjunction with the power unit 210 to transmit the magnitude of the power applied to the power device 211.

[0103] (Example 4-4) The present invention relates to a flow control valve. In Example 4-1, the receiving unit 221 includes a remote receiving unit 221-2 that receives a flow path opening signal and a flow path closing signal from the outside.

[0104] (Example 4-5) The present invention relates to a flow control valve. In Example 4-1, the sending unit 223 includes a remote sending unit 223-2 that sends the value calculated by the calculating unit 222 to an external server.

[0105] Since the receiving unit 221 that receives the measurement values ​​required by the calculation unit 222 from other structures is formed as a structure that receives flow path opening signals and closing signals from the outside, the administrator can control the phase value of the opening and closing component 111 on the flow path even when no physical operation is applied to the opening and closing unit 100.

[0106] To achieve the above structure, the receiving unit 221 may include a remote receiving unit 221-2 that receives a flow path opening signal and a closing signal from the outside. That is, the calculating unit 222 calculates whether to open or close the flow path based on the value received from the remote receiving unit 221-2.

[0107] Since the transmission unit 223, which transmits the value calculated by the calculation unit 222 to another structure, is configured to transmit the value indicating whether the flow path is open or closed to the outside, an administrator can remotely identify whether the flow path of the opening and closing unit 100 is open or closed. To implement this structure, the transmission unit 223 may include a remote transmission unit 223-2 that transmits the flow path open and closed states to the outside.

[0108] (Example 5-1) The present invention relates to a flow control valve. In Example 4-1, the calculation unit 222 includes: an opening and closing calculation unit 222-1, which determines whether the flow path is opened or closed; and an offset calculation unit 222-2, which corrects the error of the measurement value transmitted from the receiving unit 221.

[0109] (Example 5-2) The present invention relates to a flow control valve. In Example 5-1, the receiving unit 221 is configured to preferentially transmit the measurement value received from the power supply unit 230 to the offset calculation unit 222-2.

[0110] The calculation unit 222 calculates the phase value of the lifter 110 of the flow rate value passing through the corresponding flow path based on the measurement value transmitted from the receiving unit 221. To this end, the calculation unit 222 can be formed into a structure including an opening and closing calculation unit 222-1 that calculates the height value of the rise or fall of the lifter 110.

[0111] At this time, since the minimum power for maintaining the circuit is applied to the power supply unit 230, there may be an error in the power data transmitted from the receiving unit 221 to the calculating unit 222. Therefore, the calculating unit 222 may be configured to include an offset calculating unit 222-2 that corrects the error in the measurement value transmitted from the receiving unit 221.

[0112] (Example 5-3) The present invention relates to a flow control valve. In Example 5-1, the offset calculation unit 222-2 includes: a reference value setting unit 222-2A, which stores a set error range; and a comparison and judgment unit 222-2B, which compares the measurement value transmitted from the receiving unit 221 with the error value stored in the reference value setting unit 222-2A.

[0113] (Example 5-4) The present invention relates to a flow control valve. In Example 5-3, the comparison judgment unit 222-2B is formed to be a structure that only transmits the measurement value that exceeds the error range stored in the reference value setting unit 222-2A to the opening and closing calculation unit 222-1.

[0114] (Example 5-5) The present invention relates to a flow control valve. In Example 5-1, the opening and closing calculation unit 222-1 is formed as a structure for calculating the amount of power provided from the power unit 210 to the lifting unit 110.

[0115] The offset calculation section 222-2 is configured to perform error correction on the measurement value transferred from the receiving section 221. Therefore, preferably, the offset calculation section 222-2 substantially performs a function of setting an error range as a reference while correcting the error value.

[0116] To implement the above technique, the offset calculation unit 222 - 2 may include a reference value setting unit 222 - 2A storing an error range set by an administrator and a comparison judgment unit 222 - 2B comparing the stored error range with the measurement value transmitted from the reception unit 221 .

[0117] When the result calculated by the comparison judgment unit 222-2B is determined to be outside the error range, the measurement value received by the receiving unit 221 is transmitted to the opening and closing calculation unit 222-1 to calculate the height value of the lifting unit 110. In other words, the opening and closing calculation unit 222-1 can be configured to selectively calculate only the measurement value outside the error range.

[0118] (Example 6-1) The present invention relates to a flow control valve. In Example 3-1, the driving unit 200 includes a display unit that outputs data on the current position of the lifting unit 110 in the flow path.

[0119] (Example 6-2) The present invention relates to a flow control valve. In Example 6-1, the display unit includes a display window 241 that outputs the power supplied by the power unit 210 to the lifting unit 110 to the outside.

[0120] (Example 6-3) The present invention relates to a flow control valve. In Example 6-2, the display window 241 is formed of a transparent material.

[0121] The lifting unit 110 selectively opens and closes the corresponding flow path through the power unit 210. At this time, due to the structural feature that the lifting unit 110 is accommodated inside the housing 120, an administrator may not be able to intuitively identify whether the corresponding flow path is open or closed and the state of the flow passing therethrough.

[0122] To solve the above problem, the driving unit 200 may include a display unit that displays data on the phase of the lifting unit 110 and the flow rate passing through the flow path where the opening and closing unit 100 is provided.

[0123] At this time, the display unit may be formed at the lower end of the driving unit 200 and may be formed into a structure including a display window 241 for projecting the internal state. That is, through the display window 241 formed of a transparent material, the administrator can easily recognize the state of the driving unit 200.

[0124] (Example 6-4) The present invention relates to a flow control valve. In Example 6-3, the display unit includes a status display gear 242 which is coupled to the rotating shaft of the power unit 210 and is arranged opposite to the display window 241 in the thickness direction.

[0125] (Example 6-5) The present invention relates to a flow control valve. In Example 6-4, one side in the thickness direction of the status display gear 242 arranged opposite to the display window includes a spectrum 242-1 having a curvature value corresponding to the outer diameter of the status display gear 242 and including multiple colors along the length direction.

[0126] The display unit is configured to be provided at a lower end portion of the driving unit 200 to which the opening and closing unit 100 is selectively coupled, so as to convey an internal state of the driving unit 200 to a manager.

[0127] The display unit includes a status display gear 242 that projects the current status of the power unit 210 onto the display window 241 . The power unit 210 transmits the ascending or descending force to the lifting unit 110 , and the status display gear 242 may be formed as a structure combined with the power unit 210 .

[0128] At this time, the status display gear 242 may be provided with a spectrum 242-1 including a plurality of colors at a position relative to the display window 241. Since the spectrum 242-1 is formed in a shape having the same curvature value as the outer diameter of the status display gear 242, the display window 241 is formed into a structure in which different colors are displayed according to the rotation amount of the status display gear 242 rotated by the power unit 210.

[0129] (Example 7-1) The present invention relates to a flow control system using any valve in Examples 1-1 to 6-1, the flow control system comprising: a flow regulating part 10, provided with the opening and closing part 100 and the driving part 200, to control the condition of the fluid in the flow path; and a measuring part 20, respectively provided at the front end and the rear end of the flow regulating part 10, to measure the condition of the fluid in the flow path in real time.

[0130] (Example 7-2) The present invention relates to a flow control system. In Example 7-1, the measuring unit 20 is formed to be structured to send the measured value to the driving unit 200.

[0131] The smart valve of the present invention, comprising an opening / closing unit 100 and a driving unit 200, is disposed between an inlet pipe 1 and an outlet pipe 2 to selectively open and close the corresponding flow path. Specifically, the flow control system can be configured to include a flow regulating unit 10, which controls the flow rate of the opening / closing unit 100 according to the driving unit 200, and a measuring unit 20, which measures the specifications of the fluid in the flow path in real time.

[0132] The values ​​measured in real time by the measuring unit 20 are transmitted to the flow control unit 10, allowing the flow rate to be adjusted accordingly based on the conditions within the flow path. Based on the values ​​measured by the measuring unit 20, the calculation unit 222 then calculates the optimal flow rate through the corresponding flow path. Specifically, the calculation unit 222 calculates the optimal value for the rise or fall height of the lifting unit 110. Thus, the fluid specification values ​​measured by the measuring unit 20 are supplied to the receiving unit 221, preparing the calculated data for the calculation unit 222.

[0133] (Example 7-3) The present invention relates to a flow control system. In Example 7-2, the measuring unit 20 includes a pressure measuring unit 21 for measuring the pressure values ​​at the front end and the rear end of the flow regulating unit 10 in real time.

[0134] (Example 7-4) The present invention relates to a flow control system. In Example 7-2, the measuring unit 20 includes a flow rate measuring unit 22 for measuring the flow rate values ​​at the front end and the rear end of the flow regulating unit 10 in real time.

[0135] (Example 7-5) The present invention relates to a flow control system. In Example 7-2, the measuring unit 20 includes a temperature measuring unit 23 for measuring the temperature values ​​of the front end and the rear end of the flow regulating unit 10 in real time.

[0136] The measuring unit 20 is configured to be respectively installed at the front and rear ends of the flow regulating unit 10, which is composed of the opening and closing unit 100 and the driving unit 200, to measure the conditions of the inflow pipe 1 and the outflow pipe 2 in real time. In this case, the measuring unit 20 can be formed into a structure including a pressure measuring unit 21 for measuring the pressure value of the corresponding flow path in real time, a velocity measuring unit 22 for measuring the velocity value of the fluid passing through the flow path, and a temperature measuring unit 23 for measuring the temperature value of the fluid.

[0137] The flow rate regulating unit 10 can determine the height of the lifting unit 110 based on the measured values ​​of the plurality of measuring units. That is, since the flow rate control process for satisfying the conditions of the outflow pipe 2 set by the administrator is automated, the administrator's fatigue can be reduced.
