Description

Technical Field

[0001] The utility model relates to the technical field of flow meters, and more specifically, to a flow precise adjustment structure of a glass rotor flow meter. Background Art

[0002] A glass rotor flow meter is a common flow measurement device, especially suitable for liquid flow measurement. Its core part is a vertically installed conical glass tube with a smaller bottom and a larger top, and there is a float (also called a rotor) that can move up and down inside. When the liquid flows upward through this conical glass tube, the float will rise under the force of the fluid. When the upward force of the float is equal to the resultant force of the gravity of the float, the float and the viscous force, the float will reach an equilibrium position. This equilibrium position has a certain proportional relationship with the fluid flow rate passing through the flow meter, so the liquid flow rate can be measured by observing the position of the float.

[0003] Among them, through retrieval, it is found that the patent with the patent application number CN202121270228.4 discloses a flow meter on a small oxygen generator, including a flow mechanism and a backflow prevention mechanism; the flow mechanism includes a first flow tube, a vertical threaded through hole is opened at the top of the first flow tube, a metal plug is threadedly connected inside the vertical threaded through hole, three horizontal threaded through holes are opened outside the first flow tube, two metal interfaces and a regulating valve are respectively threadedly connected inside the three horizontal threaded through holes, a metal rotor is arranged inside the first flow tube, and a first scale is arranged outside the first flow tube, and the backflow prevention mechanism is installed inside the first flow tube;

[0004] When this structure is in use, through the setting of the backflow prevention mechanism, if gas backflows, the spring cooperates with the disc to block the gas flow, avoiding affecting the measurement use of the metal rotor, improving the accuracy of gas flow measurement, and being beneficial to the use of the oxygen generator. However, when this structure adjusts the flow rate, when the pressure of the fluid medium is relatively low, the spring loses a large amount of pressure, resulting in the disc returning to its position and causing a relatively low fluid passing efficiency.

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a flow precise adjustment structure of a glass rotor flow meter, aiming to solve the problems proposed in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a flow precise adjustment structure of a glass rotor flow meter, including a glass rotor flow meter main body, and a diversion component is arranged on the glass rotor flow meter main body;

[0007] The diversion component includes a first inner cylinder arranged inside the glass rotor flow meter main body, and a plurality of first conveying blades are distributed inside the first inner cylinder;

The two vertical shafts respectively extend to the middle parts of the first inner cylinder and the second inner cylinder and are rotationally connected to the first inner cylinder and the second inner cylinder. A plurality of clamps are sleeved outside the inner cylinder. A plurality of matching grooves are provided at the bottom of the main body of the glass rotor flowmeter;

[0011] It can be seen that in the above technical solution, the spiral conveying mode is formed by the first conveying blades to make the float rotate.

[0023] As shown in the attached Figures 1-5A flow precise adjustment structure of a glass rotor flowmeter is shown. Through the diversion component arranged on the glass rotor flowmeter main body 1, the horizontal axis 5 and the first baffle 6 are driven to rotate by rotating the knob 8, so that the angle of the first baffle 6 can be changed, and the air flow can be discharged from between the second baffle 7 and the first baffle 6, facilitating the air flow transportation. At the same time, when the air flow is transported into the glass rotor flowmeter main body 1, it forms a spiral transportation mode through the first conveying blade 3 and makes the float 11 rotate. It is guided by the second inner cylinder 9 and the second conveying blade 10, and the float 11 adjusts its angle, thereby adjusting the flow rate when the air flow is discharged into the second inner cylinder 9, realizing the function of the same pressure when the air flow is discharged but different flow rates during transportation. And the specific structure of the component is as follows;

[0024] The diversion component includes a first inner cylinder 2 arranged in the glass rotor flowmeter main body 1, and a number of first conveying blades 3 are distributed inside the first inner cylinder 2;

[0025] The bottom of the first inner cylinder 2 is provided with an adjustment cylinder 4. The adjustment cylinder 4 is embedded in the glass rotor flowmeter main body 1. A horizontal axis 5 is arranged in the middle of the adjustment cylinder 4. On both sides of the horizontal axis 5, there are first baffles 6 with adjustable angles, and on one side of each first baffle 6, there is a second baffle 7. The second baffle 7 is installed on the adjustment cylinder 4;

[0026] One end of the horizontal axis 5 is provided with a knob 8. The knob 8 is installed on the adjustment cylinder 4, and the knob 8 penetrates through the glass rotor flowmeter main body 1 and extends to the outside of the glass rotor flowmeter main body 1. The top of the first inner cylinder 2 is provided with a second inner cylinder 9. The second inner cylinder 9, the adjustment cylinder 4 and the first inner cylinder 2 are connected and communicated. A number of second conveying blades 10 are distributed inside the second inner cylinder 9, and each second conveying blade 10 is detachably connected to the second inner cylinder 9.

When in use, the oxygen generator is connected to the glass rotor flowmeter main body 1, and the air flow can be transported through the first inner cylinder 2 and the second inner cylinder 9. When the air flow enters the first inner cylinder 2, it is first guided by the adjustment cylinder 4. At the same time, by rotating the knob 8, the horizontal axis 5 and the first baffle 6 are driven to rotate, so that the angle of the first baffle 6 can be changed, and the air flow can be discharged from between the second baffle 7 and the first baffle 6, facilitating the air flow transportation.

[0028] When the air flow is transported into the glass rotameter main body 1 at the same time, it forms a spiral transportation mode through the first transportation blade 3 and makes the float 11 rotate. It is dredged by the second inner cylinder 9 and the second transportation blade 10, and the float 11 adjusts its angle, thereby adjusting the flow rate of the air flow when it is discharged into the second inner cylinder 9, and realizing the function of the same pressure when the air flow is discharged but different flow rates when the flow is transported.

[0029] Different from the prior art, the present application discloses a precise flow rate adjustment structure of a glass rotameter. By rotating the knob 8 to drive the horizontal shaft 5 and the first baffle 6 to rotate, the angle of the first baffle 6 can be changed, so that the air flow can be discharged between the second baffle 7 and the first baffle 6, facilitating the air flow transportation. When the air flow is transported into the glass rotameter main body 1 at the same time, it forms a spiral transportation mode through the first transportation blade 3 and makes the float 11 rotate. It is dredged by the second inner cylinder 9 and the second transportation blade 10, and the float 11 adjusts its angle, thereby adjusting the flow rate of the air flow when it is discharged into the second inner cylinder 9, and realizing the function of the same pressure when the air flow is discharged but different flow rates when the flow is transported.
