[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] The following gives specific embodiments.

[0029] Please refer to Figures 1 - 6, the present utility model provides a technical solution: a gas transmission metering device, including an outer shell cylinder 1, a valve core 2 is arranged inside the outer shell cylinder 1, a limiting component 3 is arranged on the left side of the lower part of the outer shell cylinder 1, a sensor 4 is arranged in the middle of the front side of the outer shell cylinder 1, flange plates 5 are welded and fixed on both the left and right sides of the outer shell cylinder 1, a first threaded hole 11 is opened in the middle of the upper side of the outer surface of the outer shell cylinder 1, and a first movable hole 12 is opened in the middle of the lower side of the outer surface of the outer shell cylinder 1.

[0030] Further, as Figures 3 - 5 shown, the valve core 2 includes a fixed column 21, a first connecting shaft 22 and a connecting member 23. A plurality of arc-shaped fan blades 24 are fixedly connected to the outer surface of the fixed column 21 in an equidistant circular array distribution. A second movable hole 25 is opened in the upper part of the fixed column 21. The first connecting shaft 22 is located inside the second movable hole 25 and is movably connected to the second movable hole 25. A second threaded hole 28 is opened in the lower part of the fixed column 21. The connecting member 23 includes a second connecting shaft 231. A connecting bolt 232 is fixedly connected to the upper part of the second connecting shaft 231. A gear 233 is fixedly connected to the lower part of the second connecting shaft 231. The second connecting shaft 231 is located inside the first movable hole 12 and is movably connected to the first movable hole 12, and the outer surface of the second connecting shaft 231 is in contact with the inner surface of the first movable hole 12. The connecting bolt 232 is threadedly connected to the second threaded hole 28. The gear 233 is located at the lower part of the outer shell cylinder 1. The fixed column 21 and a plurality of arc-shaped fan blades 24 are all located inside the outer shell cylinder 1, and the outer surfaces of a plurality of arc-shaped fan blades 24 are all in contact with the inner surface of the outer shell cylinder 1. A connecting thread 26 is fixedly connected to the upper part of the outer surface of the first connecting shaft 22. The first connecting shaft 22 is threadedly connected to the outer shell cylinder 1 through the connecting thread 26. An adjusting cap 27 is fixedly connected to the upper part of the first connecting shaft 22. The adjusting cap 27 is located at the upper part of the outer shell cylinder 1.

[0031] Through the above solution: By arranging the first connecting shaft 22 and the connecting member 23 for connecting the fixed column 21 and multiple arc-shaped fan blades 24 in the valve core 2, the assembly of the device during production is more convenient. At the same time, when the device is used for a long time and the multiple arc-shaped fan blades 24 are worn, it is also convenient to replace the fixed column 21 and the arc-shaped fan blades 24, which can reduce the use cost of the device.

[0032] Further, as Figure 3 and Figure 6 shown, the limiting component 3 includes a fixed block 31. An electric push rod 32 is inserted and fixedly connected to one side of the fixed block 31. An arc-shaped block 33 is fixedly connected to the output end of the electric push rod 32. A plurality of equally spaced tooth grooves 34 are opened on the side of the arc-shaped block 33 close to the valve core 2. A remote controller 35 is fixedly connected to the front part of the fixed block 31. The fixed block 31 is fixedly connected to the outer surface of the lower part of the outer shell cylinder 1. The arc-shaped block 33 can be engaged with the gear 233 through a plurality of tooth grooves 34.

[0033] Through the above solution: The remote controller 35 in the limiting component 3 can be connected to intelligent devices such as mobile phones. When it is necessary to perform an operation to close the passage of this device, an instruction can be sent to the remote controller 35 through the intelligent device, enabling the remote controller 35 to control the electric push rod 32, so that the arc-shaped block 33 limits the gear 233 in the valve core 2 through a plurality of tooth grooves 34, and the effect of closing the internal passage of the outer shell cylinder 1 by the valve core 2 can be achieved.

[0034] Working principle: Before using the device, first connect the device to the gas pipeline through two flange plates 5, and then connect the device to the power supply to use it. When the device is in use, gas flows through, the fan blades rotate, and the sensor 4 monitors the rotation speed of the fan blades to know the specific gas flow rate. When there is a leakage at the end of the gas pipeline and it is necessary to close the device, or when it is necessary to temporarily close the device, an instruction can be directly sent to the remote controller 35 in the limiting component 3 through an intelligent device (such as a smart phone), enabling the remote controller 35 to control the electric push rod 32 to push the arc-shaped block 33, and the arc-shaped block 33 engages and limits the gear 233 at the lower part of the valve core 2 through the tooth grooves 34 opened on one side. When the arc-shaped fan blade 24 cannot rotate, the effect of closing the inside of the outer shell cylinder 1 can be achieved through the arc-shaped fan blade 24, preventing gas from continuing to flow through the outer shell cylinder 1. When it is necessary to continue using the device later, the remote controller 35 is controlled again through the intelligent device to separate the arc-shaped block 33 from the gear 233 in the valve core 2, and the device can continue to be used.

[0035] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
