The valve core is used to block the sealing port and the valve core is set in the second flow channel. Therefore, under the high-pressure environment of the natural gas equipment, the valve can also be automatically closed. During differential pressure filling, the pressure of the first channel is higher than that of the second flow channel. The liquefied natural gas pressure gives the valve core an upward thrust, which is used to make the valve core upwardly detach from the sealing port, and the limit device limits the valve core in the direction of the thrust, so that the valve core can keep the valve core from moving upward even under the action of the thrust, blocking the sealing port, and when the intelligent valve is not opened for filling, the sealing port is not completely sealed, so the filling speed will become very slow, and the limit of the valve core by the filling limit device can only be released by the rotation of the rotating motor, and the rotating motor can only be remotely driven by the connection between the communication device and the control device. After the rotating motor is set in the protective cover, there is no other driving method to drive the rotating motor to rotate. Therefore, the valve core cannot be opened before the limit device releases the limit on the valve core. After the limit device is opened, the control device will automatically start timing, and after the time is up, it will drive the motor to close the limit. In case the external power is lost, the battery inside will be used to power the control board to close the limit device, thereby preventing others from stealing the natural gas in the natural gas using equipment.

[0018] Therefore, the present application has the characteristics of reasonable structure and convenient use. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0029] There are defects in the anti-theft measures of natural gas equipment in the prior art, and the natural gas may still be stolen.

[0031] Example:

[0032] Figures 1 to 8 An embodiment of the smart valve of the present application is presented.

[0033] Please refer to Figure 1 In the specific embodiment of the present application, a smart valve is shown, including a valve body 1 and a valve core 2. The natural gas in the smart valve is turned on and off by the cooperation between the valve body 1 and the valve core 2. Please refer to Figure 2As shown, a flow channel is arranged in the valve body 1, and the flow channel includes a first flow channel 3 and a second flow channel 4. The first flow channel 3 is connected to the filling equipment, and the second flow channel 4 is connected to the natural gas using equipment. The first flow channel 3 is connected to the second flow channel 4 through a sealing port, and the valve core 2 is used to open or close the sealing port 5. The valve core 2 is arranged in the second flow channel 4.

[0034] A limiting device is provided on one side of the valve core 2, and the limiting device is connected to the rotating motor 6. Under the rotation of the limiting device, the valve core 2 includes an open state and a closed state. Figure 5 and Figure 6 As shown, when the valve core 2 completely blocks the sealing port 5 in the valve body 1, the valve core 2 is in a closed state, and natural gas cannot pass through the flow channel. Figure 7 and Figure 8 As shown, when the valve core 2 is upwardly separated from the sealing port 5, the valve core 2 is in an open state, and natural gas can pass through the flow channel. Whether the valve core 2 is in an open state or a closed state is determined by a limit device, which is further driven by a rotating motor 6. The communication device 8 is connected to the rotating motor 6 through the control device 7.

[0035] The smart valve in this embodiment is a one-way valve. The liquefied natural gas always flows from the first flow channel 3 to the second flow channel 4 through the sealing port 5. The valve core 2 is used to seal the sealing port and the valve core 2 is arranged in the second flow channel 4. Therefore, in the differential pressure filling environment of the filling equipment, the liquefied natural gas always gives the valve core 2 an upward thrust, and the thrust is used to make the valve core 2 upwardly detach from the sealing port, and the limit device limits the valve core 2 in the direction of the thrust, so that the valve core 2 can keep sealing the sealing port 5 even under the action of the thrust. The outer cover of the rotating motor 6 is provided with a protective cover, and the protective cover sets the rotating motor 6 inside to block other connection modes between the rotating motor 6 and the outside world, so that the rotating motor 6 can only be started through the remote connection of the communication device 8. Moreover, the limit device can only be driven by the rotating motor 6, thereby avoiding the possibility of natural gas being stolen.

[0036] During the specific operation, the operator sends a signal to the communication device 8. After receiving the signal, the communication device 8 controls the rotation of the rotating motor 6 through the control device 7, and further drives the rotation of the limit device. Under the rotation of the limit device, the valve core 2 is switched between the open state and the closed state. Therefore, before the limit device releases the limit of the valve core, the valve core cannot be opened. After the limit device is turned on, the control device will automatically count down, and when the time is up, it will drive the motor to close the limit. In case of external power loss, the battery inside will be used to power the control panel and close the limit device, thereby preventing others from stealing the natural gas in the natural gas equipment.

[0037] In the specific embodiment of the application, the limit device includes a stopper 9 and a push rod 10. The first end of the push rod 10 is connected to the rotary motor 6, and the second end of the push rod 10 is provided with a stopper 9. When the rotary motor 6 rotates, the stopper 9 is driven to rotate through the push rod 10. The stopper 9 is arranged in the second flow channel 4, and the valve core 2 is provided with an adjustment hole 21 for the stopper 9 to pass through.

[0038] Under the rotation of the rotating motor 6, the stopper 9 rotates synchronously in the circumferential direction to form the first position and the second position. Figure 5 and Figure 6 As shown, when the stopper 9 is in the first position, the stopper 9 is offset from the adjustment hole 21, and one end of the stopper 9 abuts against one end of the valve core 2. At this time, the valve core 2 is restricted between the stopper 9 and the sealing port 5, and the valve core 2 blocks the sealing port 5 to form a closed state of the valve core 2. The liquefied natural gas cannot flow out of the sealing port 5, and when the smart valve is not opened for filling, the sealing port is not completely sealed, so the filling speed will become very slow. Figure 7 and Figure 8 As shown, when the stopper 9 is in the second position, the stopper 9 is arranged corresponding to the adjustment hole 21, and the stopper 9 is located in the adjustment hole 21. The liquefied natural gas forms an upward thrust on the stopper 9 during the flow from the first flow channel 3 to the second flow channel 4. Since the stopper 9 is in the adjustment hole 21 and has the thrust, the valve core 2 moves upward along the stopper 9 and then separates from the sealing port 5. In this way, the liquefied natural gas can flow from the first flow channel 3 to the sealing port 5 and then into the second flow channel 4 to form the open state of the valve core 2.

[0039] Among them, when the stopper 9 corresponds to the adjustment hole 21, all positions of the stopper 9 when the stopper 9 is in the adjustment hole 21 can be called the second position. When the stopper 9 is misaligned with the adjustment hole 21, all positions when the stopper 9 abuts against one end of the valve core 2 can be called the first position. There can be multiple first positions and multiple second positions.

[0040] In a preferred state, a plurality of stop blocks 9 may be provided, which are circumferentially arranged on the periphery of the push rod 10 , and the stop blocks 9 may be arranged perpendicular to the center line of the push rod 10 .

[0041] In a specific embodiment of the present application, the protective cover includes a cover body 11 and a bottom plate 12, and the cover body 11 is a shell with an opening downward. The bottom plate 12 is fixedly arranged at the bottom of the cover body 11 to form a blockage for the opening at the bottom of the cover body 11. In a preferred state, the bottom plate 12 is fixedly connected to the cover body 11 by anti-disassembly screws, and the rotating motor 6, the control device 7 and the communication device 8 are all arranged in the protective cover. The protective cover cannot be opened by any means such as violent dismantling, so the rotation of the rotating motor 6 can only be achieved remotely. The inside of the protective cover is sealed with packing.

[0042] A center hole is provided on the bottom plate 12 , a bearing is provided in the center hole, and the top rod 10 is rotatably connected to the bearing.

[0043] In the specific embodiment of the present application, the rotating motor 6 is connected to the power supply through the control device 7, and the power supply includes an internal power supply 13 and an external power supply 14. The internal power supply 13 is arranged inside the protective cover, and the external power supply 14 is arranged outside the protective cover. A through hole is arranged on the cover body 11. The size of the through hole is not enough to realize the driving of the rotating motor 6 by other means, and the through hole is only used for the power line to pass through. After the wire is connected to the rotating motor 6, it passes through the through hole and is connected to the external power supply 14. If someone deliberately cuts off the external power supply, the control device 7 uses the internal power supply 13 as a standby power supply to drive the rotating motor 6.

[0044] Please refer to Figure 2 In the specific embodiment of the present application, a partition 15 is disposed transversely in the flow channel, and the partition 15 divides the flow channel into a first flow channel 3 and a second flow channel 4, wherein the first flow channel 3 is at the top and the second flow channel 4 is at the bottom. A sealing port 5 is disposed on the partition 15, and a sealing ring 22 is disposed on the side of the valve core 2 close to the sealing port 5. The sealing ring 22 is disposed around the bottom of the valve core, and the sealing ring 22 directly abuts against the partition to enhance the sealing performance of the valve core 2 in the closed state. In the preferred state, the sealing ring 22 is made of polytetrafluoroethylene.

[0045] Please refer to Figure 3 and Figure 4 In a specific embodiment of the present application, the adjustment hole 21 includes a first adjustment hole 16 and a second adjustment hole 17. The first adjustment hole 16 is located at the center of the valve core 2, and the second adjustment hole 17 is located on one side of the first adjustment hole 16. The first adjustment hole 16 is connected to the second adjustment hole. The valve core 2 is sleeved on the outside of the push rod 10 through the first adjustment hole 16, and the second adjustment hole 17 is used to accommodate the stop block 9.

[0046] In a preferred state, the first adjustment hole 16 is cylindrical, the second adjustment hole 17 is rectangular, two second adjustment holes 17 are arranged along the circumference of the first adjustment hole 16, and two top blocks are also arranged correspondingly, and the two top blocks are arranged circumferentially around the top rod 10. When the stop block 9 is in the second position, the stop block 9 is located in the second adjustment hole 17.

[0047] Please refer to Figure 3 In a specific embodiment of the present application, the first adjustment hole 16 is a through hole, the second adjustment hole 17 is a blind hole, the opening of the second adjustment hole 17 is arranged toward the stop block 9, a valve cover 18 is arranged on the top of the valve core 2, and the valve cover 18 is connected to the valve body 1. After the limit device contacts the limit of the valve core 2, the liquefied natural gas drives the valve core 2 to move upward until the valve core 2 and the valve cover 18 are abutted, thereby preventing the valve core 2 from being out of the stroke during the upward movement.

[0048] In a specific embodiment of the present application, a liquid inlet 19 is provided at one end of the first flow channel 3, and the first flow channel 3 is connected to the filling equipment through the liquid inlet 19. A liquid outlet 20 is provided at the first end of the second flow channel 4, and the second flow channel 4 is connected to the natural gas using equipment through the liquid outlet 20. The liquid inlet 19 and the liquid outlet 20 are provided at both ends of the valve body 1.

[0049] Please refer to Figure 3 and Figure 4 As shown, in the embodiment of the present application, the valve core 2 is a stepped shaft structure, and the valve core 2 includes an upper shaft 23 and a lower shaft 24 arranged up and down, the lower shaft 24 is used to set the sealing ring 22, and the upper shaft 23 is used to set the adjustment hole 21. In a preferred state, the diameter of the upper shaft 23 is smaller than the diameter of the lower shaft 24, and the upper shaft 23 and the lower shaft 24 form a shaft shoulder. When the liquefied natural gas needs to flow from the second flow channel 4 to the first flow channel 3, the liquefied natural gas and the shaft shoulder act to push the valve core 2 against the sealing port 5 to form a one-way flow of the valve body 1.

[0050] In a specific embodiment of the present application, a sliding limit structure is provided between the valve body 1 and the valve core 2. The setting of the sliding limit structure allows the movement between the valve body 1 and the valve core 2 to remain relatively stable.

During the switching process between the closed state and the open state, the slider 26 is always slidably provided in the slide groove 25. The matching setting of the slide groove 25 and the slider 26 prevents the valve core 2 from rotating circumferentially.
