[0003] In existing technologies, when filling gas cylinders, it is impossible to monitor the flow rate of the fluid entering the cylinder, and manual reading of the pressure inside the cylinder using a pressure gauge is required before stopping the filling. This process is time-consuming and labor-intensive, the pressure value read manually is inaccurate, and the cylinder valve cannot be closed in time. Gas cylinders may leak during daily use or storage, and manual monitoring and timely troubleshooting are not possible, posing safety hazards. Utility Model Content

[0006] The valve body has an angle valve motor installed at its top.

[0007] The valve core is disposed within the valve body;

[0008] A valve stem is disposed within the valve body; one end of the valve stem is connected to the output end of the angle valve motor, and the other end is connected to the valve core.

[0009] Furthermore, a first opening is provided on the outer wall of the valve core; a second opening is provided on the end of the valve core away from the valve stem; the first opening and the second opening are connected to form an L-shaped channel.

[0010] Furthermore, the arc length of the arc-shaped cross-section of the first opening is less than the perimeter of the cross-section of the valve core.

[0011] Furthermore, a steel cylinder includes a cylinder body and a smart angle valve connected to a port of the cylinder body, wherein the smart angle valve is any of the smart angle valves described above.

[0012] Furthermore, including:

[0013] A flow monitoring unit is connected to the inlet of the smart angle valve to monitor the flow rate of fluid entering the bottle.

[0014] A pressure monitoring unit is disposed inside the bottle to monitor the pressure inside the bottle;

[0015] The control unit is fixedly connected to the outer wall of the bottle; the control unit is electrically connected to the intelligent angle valve, the pressure monitoring unit, and the pressure monitoring unit respectively.

[0018] Furthermore, the pressure monitoring unit includes a pressure sensor; the pressure sensor is disposed inside the bottle to monitor the pressure inside the bottle.

[0019] Furthermore, it also includes an alarm; the alarm is electrically connected to the control unit.

[0020] Beneficial effects:

[0021] This utility model provides an intelligent angle valve and a gas cylinder. A pressure sensor monitors the pressure inside the cylinder. During inflation, a flow sensor electrically connects to the control unit, changing the rotation direction of the valve core to control the flow rate of fluid entering the cylinder. When the pressure reaches a set value, the control unit controls the angle valve motor to close the valve, achieving automatic closure when the pressure inside the cylinder reaches a certain level. When the cylinder is not in use, the pressure sensor can still monitor the pressure inside. If the cylinder leaks, the pressure changes, and the control unit activates an alarm to alert the user of the leak and eliminate potential safety hazards. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] Example 1

[0032] like Figures 1 to 4 As shown, an intelligent angle valve includes:

[0033] Valve body 2, with an angle valve motor installed at the top inside the valve body 2;

[0034] Valve core 3 is disposed inside valve body 2;

[0035] Valve stem 4 is located inside valve body 2; one end of valve stem 4 is connected to the output end of angle valve motor, and the other end is connected to valve core 3.

[0036] In this embodiment, a first opening 5 is provided on the outer wall of the valve core 3; a second opening 6 is provided on the end of the valve core 3 away from the valve stem 4; the first opening 5 and the second opening 6 are connected to form an L-shaped channel.

[0037] A sealing gasket is provided between one end of the second opening 6 of the valve core 3 and the port of the bottle body 1.

[0038] In this embodiment, the arc length of the arc-shaped cross-section of the first opening 5 is less than the perimeter of the cross-section of the valve core 3.

[0039] Example 2

[0040] A steel cylinder includes a cylinder body 1 and an intelligent angle valve connected to a port on the cylinder body 1. The intelligent angle valve is the intelligent angle valve in Example 1.

[0041] In this embodiment, it includes:

[0042] A flow monitoring unit is connected to the inlet 10 of the smart angle valve to monitor the flow rate of fluid entering the bottle 1;

[0043] A pressure monitoring unit is installed inside the bottle body 1 to monitor the pressure inside the bottle body 1;

[0044] Control unit 7 is fixedly connected to the outer wall of bottle 1; control unit 7 is electrically connected to intelligent angle valve, pressure monitoring unit and pressure monitoring unit respectively.

[0045] The angle valve motor of the intelligent angle valve is electrically connected to the control unit 7.

[0046] In this embodiment, the second opening 6 of the smart angle valve is connected to the port of the bottle body 1.

[0047] In this embodiment, the flow monitoring unit includes a flow sensor 8; the flow sensor 8 is connected to the inlet 10 of the smart angle valve.

[0048] In this embodiment, the pressure monitoring unit includes a pressure sensor; the pressure sensor is disposed inside the bottle 1 to monitor the pressure inside the bottle 1.

[0049] In this embodiment, an alarm 9 is also included; the alarm 9 is electrically connected to the control unit 7.

[0050] Through the above technical solution, the angle valve motor drives the valve core 3 to rotate through the valve stem 4. As the valve core 3 rotates, the first opening 5 of the valve core 3 gradually comes into contact with the inner wall of the valve body 2, so that the overlapping area of ​​the first opening 5 of the valve core 3 and the inlet 10 of the valve body 2 gradually decreases until the first opening 5 of the valve core 3 is completely in contact with the inner wall of the valve body 2, so that the first opening 5 of the valve core 3 is no longer exposed at the inlet 10 of the valve body 2, thereby realizing the closing of the angle valve.

[0051] This utility model provides an intelligent angle valve and a gas cylinder. A pressure sensor and a flow sensor 8 are electrically connected to a control unit 7. During inflation, the pressure sensor monitors the pressure inside the cylinder 1. Upon receiving the signal from the pressure sensor, the control unit 7 drives the angle valve motor to rotate. This rotation drives the valve core 3 of the intelligent angle valve to rotate, changing the overlap area between the first opening 5 of the valve core 3 and the inlet 10 of the valve body 2, thus controlling the flow rate of fluid entering the gas cylinder 1. When the pressure inside the cylinder 1 reaches a set value, the control unit 7 controls the angle valve motor to drive the valve core 3 to rotate, making the first opening 5 of the valve core 3 completely fit against the inner wall of the valve body 2, closing the angle valve and achieving automatic closure of the intelligent angle valve. When the gas cylinder is not in use, the pressure sensor can still monitor the pressure inside the cylinder 1. When the gas cylinder leaks, the pressure inside the cylinder 1 changes. The pressure sensor detects this change, and upon receiving the signal from the pressure sensor, the control unit 7 activates the alarm 9 to alert of the leak and eliminate potential safety hazards.

[0052] The above are merely preferred embodiments of the present utility model and do not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
