Description

Technical Field

[0001] This utility model relates to the field of flow meters, and more specifically, to a flow meter control structure. Background Technology

[0002] Flow meters are widely used for measuring fluid flow. In existing technology, when regulating pipeline flow, the flow meter and independent control valve are typically installed separately: the flow meter measures the flow, and its signal is transmitted to the control system, which then drives the independent valve installed upstream or downstream of the flow meter to perform the regulating action. While integrated flow controllers combine measurement, calculation, and execution functions, their valve actuators are usually still physically separate from the flow meter body, requiring external connection for linkage.

[0003] The aforementioned separate structure has significant drawbacks: First, it requires additional valves, actuators, and connecting pipelines, resulting in a complex system structure, large space occupation, high installation costs, and numerous potential leakage points. Second, the flow measurement signal needs to go through multiple stages such as transmission, calculation, and driving before it can act on the valve, causing a delay in the control loop. This severely restricts the response speed and control accuracy of flow regulation, and is prone to overshoot or oscillation, especially under dynamic operating conditions.

[0004] Furthermore, flow field disturbances caused by external valve operation can affect the flow meter's measurement accuracy, and the separate structure leads to cumbersome maintenance and calibration. Therefore, there is an urgent need for an integrated solution that can fundamentally simplify the structure, shorten the control loop, and improve response and accuracy. Utility Model Content

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] Reference Figures 1 to 2 The embodiments of this utility model will be further described below.

[0022] To achieve the above objectives, this utility model provides the following technical solution: a flow meter control structure, including a flow meter body, the flow meter body including a housing 1 and a control valve 2, a flow channel 3 formed inside the housing 1, the control valve 2 being disposed in the flow channel 3 and controlling its cut-off and connection, the presence of the control valve 2 makes the flow adjustment operation simpler and more efficient and more convenient.

[0023] The housing 1 is provided with a drive component that connects to and drives the control valve 2 to open and close. The drive component includes a drive rod 4, which rotates to connect to the control valve 2. The drive rod 4 is provided on the housing 1, which allows the valve to be opened and closed manually. At the same time, the manual method allows for more precise flow adjustment, making the operation convenient and the adjustment more accurate. The housing 1 is also equipped with a control component 7 that connects to the control valve 2. The control component 7 drives the opening and closing of the control valve 2. In practical use, a drive mechanism such as a motor can be installed as the actuator of the control valve 2, and electronic control software can be installed on the housing 1 to achieve remote control and flow regulation. This is suitable for environments where manual operation is difficult or impossible. These two different methods can be applied to different environments, making the use more convenient and wider in scope.

[0024] The control valve 2 includes a butterfly valve. The large diameter design of the butterfly valve makes the valve body channel basically the same as the inner diameter of the flow meter, so that the medium flows smoothly and the pressure loss is low, which is especially suitable for high flow conditions. It is small in size and light in weight, making it easy to install in narrow spaces and reducing the load on the support and the stress on the pipeline.

[0025] In some environments, it can be replaced with a ball valve, which is easy to operate, has flow regulation capability, and its material inertness ensures performance. Its opening and closing parts only require a 90° rotation to open or close, making operation simple and quick; In some very special cases, a shut-off valve can be used to regulate the flow rate of the flow meter, and it can be used according to the actual situation.

[0026] The butterfly valve is detachably mounted on the housing 1 for easy replacement and maintenance. In actual use, the valve and flow meter can be integrated into one design according to requirements, which can facilitate production and use.

[0027] A sensor is also installed in the flow channel 3, which allows for a more intuitive view of changes in the flow rate within the flow meter.

[0028] The outer periphery of the housing 1 is provided with a connecting part 5, and the connecting part 5 is provided with a plurality of connecting rods 53 for easy installation and connection.

[0029] Both ends of the housing 1 are provided with connectors. The connectors include a connecting sleeve 6 and a locking clip 61. The connecting sleeve 6 is fixed to the housing 1, and the locking clip 61 is disposed on the outer periphery of the connecting sleeve 6 and drives the connecting sleeve 6 to engage, so as to facilitate the connection of the two ends of the flow meter to the pipeline.

[0030] The flow channel 3 is equipped with a filter screen 8 to facilitate the filtration of the flow meter fluid.

[0031] The flow channel 3 is equipped with a rotating paddle 9 and a fixed frame 93. The fixed frame 93 is fixed to the housing 1, and the rotating paddle 9 is rotatably connected to the fixed frame 93. The rotating paddle 9 can boost the flow, making it easier for the flow to flow away faster.

[0032] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
