Description

Technical Field

[0001] This utility model belongs to the field of flow controller technology, and specifically relates to a flow controller that is easy to adjust. Background Technology

[0002] A flow controller is a device used to precisely control the flow rate of fluids, liquids, or gases. It monitors the actual flow rate and compares it with a set value, automatically adjusting the position of valves or other actuators to maintain the fluid flow rate within a predetermined range. Flow controllers are widely used in industrial automation, environmental monitoring, chemical processing, pharmaceuticals, food and beverage production, and other fields to ensure stable and accurate fluid flow in the process.

[0003] In existing technologies, traditional flow controllers do not incorporate buffer components to prevent water hammer or other forms of pressure shocks that can occur when fluids start or stop rapidly or when pressure fluctuates in the system. These shocks can cause mechanical stress on the internal components of the flow controller, such as valves, sensors, and actuators, leading to wear or damage. At the same time, frequent shocks can accelerate the fatigue of critical components, shorten their service life, and increase maintenance frequency and replacement costs. Utility Model Content

[0004] The purpose of this invention is to provide an easily adjustable flow controller, which aims to solve the problem that traditional flow controllers in the prior art do not have buffer components, so when the fluid starts or stops quickly in the system or when the pressure fluctuates, water hammer or other forms of pressure shock will occur. These shocks will cause mechanical stress on the internal components of the flow controller, such as valves, sensors and actuators, leading to wear or damage.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A rotating shaft, which is rotatably connected inside the impact rod;

[0012] Turbine blades, which are fixedly connected to the circumferential surface of the rotating shaft.

[0013] In a preferred embodiment of this utility model, each buffer has two sliding grooves, and each sliding groove has a slider slidably connected to it. An impact rod is fixedly connected to the slider, and a spring is fixedly connected to the buffer.

[0014] As a preferred embodiment of this utility model, two fixing rings are fixedly connected to the circumferential surface of the buffer, and multiple support rods are fixedly connected to the two ends of the two fixing rings respectively.

[0017] As a preferred embodiment of this utility model, two connecting pipes are fixedly connected to both ends of the tube body, and two filter screens are fixedly connected inside the two connecting pipes.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. In this design, the impact rod can slide smoothly within the buffer to respond to changes in fluid pressure.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example

[0029] Please see Figures 1-4 The present invention provides the following technical solution:

[0030] An easily adjustable flow controller includes:

[0031] tube body 1;

[0032] Flow sensor 2 is installed inside pipe body 1;

[0033] Buffer 3 is fixedly connected to the front end of flow sensor 2;

[0034] Impact rod 4 is slidably connected within buffer 3;

[0035] Rotating shaft 5 is rotatably connected to the impact rod 4;

[0036] Turbine blade 6 is fixedly connected to the circumferential surface of the rotating shaft 5.

[0037] In a specific embodiment of this utility model, firstly, the pipe body 1 serves as the main channel for the fluid, with a built-in flow sensor 2 for real-time monitoring of the flow rate. When a change in flow rate is detected, a buffer 3 is fixed to the front end of the flow sensor 2, which can absorb and mitigate the impact force of the fluid, ensuring stable system operation. The impact rod 4 is located inside the buffer 3 and can slide according to changes in fluid pressure, converting the fluid pressure into mechanical motion. The rotating shaft 5 passes through the impact rod 4 and can rotate freely, transforming the linear motion of the impact rod 4 into rotational motion, thereby adjusting the angle or speed of the turbine blades 6. The turbine blades 6 are fixed on the rotating shaft 5 and rotate together with the rotating shaft 5, completing the energy transfer and conversion process. The design of the entire system is easy to adjust because by changing the position of the impact rod 4 or the rotation angle of the rotating shaft 5, it can quickly respond to and adapt to different flow requirements, thereby achieving precise control and efficient adjustment, improving the system's response speed and stability, and reducing the impact of external interference.

[0038] Please refer to the details. Figures 1-4 Each buffer 3 has two sliding grooves 7, and each sliding groove 7 has a slider 8 slidably connected to it. The slider 8 has an impact rod 4 fixedly connected to it, and the buffer 3 has a spring 9 fixedly connected to it.

[0039] In this embodiment, the impact rod 4 can slide smoothly within the buffer 3 to respond to changes in fluid pressure. A spring 9 is also fixedly connected inside the buffer 3 to provide a reaction force when the impact rod 4 moves, helping it to reset and absorb impact energy. This design, through the cooperation of the slider 8 and the sliding groove 7, ensures that the impact rod 4 can move smoothly and accurately, while the spring 9 ensures the stability and response speed of the system, realizes rapid adjustment of flow rate changes, reduces mechanical wear, and improves the durability and reliability of the equipment.

[0040] Please refer to the details. Figures 1-4 Two fixed rings 10 are fixedly connected to the circumferential surface of the buffer 3. Multiple support rods 11 are fixedly connected to the two ends of the two fixed rings 10 respectively. Multiple support rods 11 are fixedly connected inside the tube body 1.

[0041] In this embodiment, the support rod 11 is not only connected to the fixing ring 10, but also fixedly connected inside the tube body 1. This design allows the buffer 3 to be stably installed inside the tube body 1, and the structure of the fixing ring 10 and the support rod 11 ensures that the buffer 3 maintains a stable position during operation, preventing it from shifting or shaking. The number and distribution of the support rods 11 ensure sufficient mechanical strength and support force, thereby maintaining the structural stability of the entire system. The advantage of this linkage mechanism is that it enhances the overall rigidity and reliability of the equipment, ensures that the buffer 3 can effectively absorb and disperse impact force, and ensures that the system can still operate smoothly under high load conditions, thereby improving the durability and overall performance of the equipment.

[0042] Please refer to the details. Figures 1-4 A connector 12 is fixedly connected inside the pipe body 1, and a flow sensor 2 is fixedly connected to the lower end of the connector 12.

[0043] In this embodiment, the flow sensor 2 is securely installed inside the pipe body 1 through the connector 12, ensuring that the flow sensor 2 can accurately detect the flow rate flowing through the pipe body 1. The connector 12 not only provides physical support, but also ensures the sealing and stability between the flow sensor 2 and the pipe body 1, preventing leakage or loosening.

[0044] Please refer to the details. Figures 1-4 The upper end of connector 12 is fixedly connected to controller 13.

[0045] In this embodiment, the controller 13 can receive data from the flow sensor 2 and process and analyze the data to control the actions of other related components, such as adjusting the valve opening or adjusting the flow rate.

[0046] Please refer to the details. Figures 1-4 Two connecting pipes 14 are fixedly connected to both ends of the pipe body 1, and two filter screens 15 are fixedly connected inside the two connecting pipes 14.

[0047] In this embodiment: the pipe body 1 is connected to other pipeline systems through the connecting pipe 14, and a filter screen 15 is installed inside the connecting pipe 14 to intercept impurities and particulate matter in the fluid, preventing them from entering the pipe body 1 or affecting the normal operation of the flow sensor 2 and other components.

[0048] The working principle and usage process of this utility model are as follows: First, the fluid enters the system through the connecting pipe 14, undergoes preliminary filtration through the filter screen 15 to remove impurities and particulate matter, and then enters the pipe body 1. The flow rate is monitored by the flow sensor 2. The buffer 3 is located in front of the flow sensor 2 to absorb the fluid impact force and ensure stable operation of the system. The impact rod 4 slides in the sliding groove 7 inside the buffer 3, moves according to the fluid pressure changes, and achieves reset and buffering through the action of the slider 8 and the spring 9. The movement of the impact rod 4 drives the rotating shaft 5 to rotate, which in turn drives the turbine blades 6 to rotate, completing the mechanical motion conversion. The fixing ring 10 and the support rod 11 ensure that the buffer 3 is firmly installed in the pipe body 1 to prevent displacement or shaking. The connector 12 connects the flow sensor 2 to the controller 13. The controller 13 receives and processes flow data and issues commands to adjust the flow as needed. Through the close linkage between its components, the entire device achieves precise control and efficient adjustment of the flow. The filter 15 ensures fluid cleanliness, extends equipment lifespan, and improves system reliability and stability. By using this device, the problem of traditional flow controllers not adding buffer components is solved. This causes water hammer or other forms of pressure shocks when the fluid starts or stops rapidly or when pressure fluctuates in the system. These shocks can cause mechanical stress on the internal components of the flow controller, such as valves, sensors, and actuators, leading to wear or damage. At the same time, frequent shocks can accelerate the fatigue of key components, shorten their lifespan, and increase maintenance frequency and replacement costs.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
