[0002] Flow rate usually refers to the amount of fluid flowing through a closed pipe section per unit time. Flow meters, as common flow measurement devices, are widely used in the fields of steel, metallurgy, water supply, drainage, petroleum, chemical industry, agricultural irrigation, etc. Flow meters measure flow and provide accurate values ​​for managers or control systems so that they can make reasonable judgments and adjustments. In addition, flow meters continuously accumulate total values ​​over a period of time, which can also be used for trade settlement or to measure the total volume (total mass) of fluids, such as oil, water, heat, etc. as commodities for sale. Liquid flow can be measured by common flow detectors, which ensures real-time detection and viewing of flow values, making it easier for users to adjust liquid flow in real time.

The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0019] Embodiment:

[0020] like Figure 1-4 As shown, the utility model provides a liquid flow detector, including a liquid pipeline 1, a connecting branch pipe 2 is fixedly connected to the middle outer surface of the liquid pipeline 1, an annular groove 23 is provided on the top of the connecting branch pipe 2, a sealing ring 24 is provided inside the annular groove 23, a lower positioning groove 21 is provided on the lower inner side of the connecting branch pipe 2, a side positioning groove 22 is provided on the upper side of the connecting branch pipe 2, a flow detector 3 is provided on the top of the connecting branch pipe 2, a side positioning block 38 is fixedly provided on one side of the bottom of the flow detector 3, and the side positioning block 38 is engaged with the side positioning groove 22, a fixing component is provided on the lower side of the flow detector 3, and the fixing component is used to fix the connecting branch pipe 2 and the flow detector 3.

[0021] The fixing parts include a mounting frame plate 31, a movable groove 32, a movable block 33, a moving block 34, a threaded rod 35, a connecting rod 36, and a fixed clamping plate 37. The mounting frame plate 31 is fixedly provided on the lower side of the flow detector 3. A movable groove 32 is provided on the side of the mounting frame plate 31. The movable block 33 is slidably connected inside the movable groove 32. The moving block 34 is fixedly provided on the side of the moving block 33. The threaded rod 35 is rotatably connected inside the mounting frame plate 31, and the threaded rod 35 is threadedly connected to the moving block 34. A connecting rod 36 is fixedly provided on the bottom of one end of the moving block 34, and the connecting rod 36 is slidably connected to the mounting frame plate 31. A fixed clamping plate 37 is fixedly provided on the bottom end surface of the connecting rod 36, and the top of the fixed clamping plate 37 is arranged to fit the lower inner side of the connecting branch pipe 2.

[0022] When it is necessary to separate the flow meter 3 from the connecting branch pipe 2 on the liquid pipeline 1, the threaded rod 35 is rotated. Since the threaded rod 35 is threadedly connected to the moving block 34, and the movable block 33 is slidably connected to the movable groove 32, and the moving block 34 is fixedly connected to the movable block 33, the threaded rod 35 can drive the moving block 34 to move vertically downward when it rotates. When the moving block 34 moves downward, it drives the connecting rod 36 downward. When the connecting rod 36 moves downward, it drives the fixed clamping plate 37 downward, so that the fixed clamping plate 37 can be separated from the inner side of the connecting branch pipe 2. At this time, the flow meter 3 is moved horizontally to the side as a whole, so that the fixed clamping plate 37 is detached from the lower inner side of the connecting branch pipe 2. At this time, the flow meter 3 can be moved upward to remove the flow meter 3 from the connecting branch pipe 2. Similarly, the above operation , the flow meter 3 and the connecting branch pipe 2 can be conveniently installed. At the same time, when the flow meter 3 and the connecting branch pipe 2 are fitted and fixed, the sealing ring 24 can seal the connection between the connecting branch pipe 2 and the flow meter 3 under the engagement connection between the sealing ring 24 and the annular groove 23, so that the sealing of the flow meter 3 and the connecting branch pipe 2 can be ensured to prevent liquid leakage. Through this design, under the operation of the fixing component, the flow meter 3 and the connecting branch pipe 2 on the liquid pipeline 1 can be conveniently disassembled and assembled, and the top end of the threaded rod 35 is set on the upper side of the flow meter 3, so that the threaded rod 35 can be rotated more conveniently, and the situation that the disassembly and assembly of the flow meter 3 is extremely inconvenient due to the small space for disassembly and assembly of the pipeline is avoided, thereby improving the work efficiency of the staff and the comfort of operation.

[0024] Among them, the internal width of the side positioning groove 22 is adapted to the width of the side positioning block 38; by adapting the sizes of the side positioning groove 22 and the side positioning block 38, when the side positioning block 38 is engaged with the side positioning groove 22, the contact surface between the connecting branch pipe 2 and the flow detector 3 can be limited, thereby avoiding positional deviation after the connecting branch pipe 2 and the flow detector 3 are in contact and fixed.

[0025] Among them, the internal width of the movable groove 32 is adapted to the width of the movable block 33, and a turntable is fixedly provided on the top surface of the threaded rod 35; by adapting the sizes of the movable groove 32 and the movable block 33, the movable block 33 can be made more stable when moving inside the movable groove 32, so that the threaded rod 35 can drive the movable block 34 to move vertically downward when rotating, while ensuring the stability of the movable block 34 when moving downward to avoid its position displacement.
