Description

Technical Field

[0001] This utility model relates to the field of stopper rod flow control technology, and in particular to an automatic stopper rod flow control device for pipelines. Background Technology

[0002] The technology of stopper rod flow control devices can be traced back to the early industrial need for fluid flow control. With the continuous development of industrial technology, the precise control of fluid flow has become increasingly important, especially in industries such as metallurgy, chemical industry, and energy. As an effective means of flow control, stopper rod flow control devices have gradually been widely used in these industries. The working principle of stopper rod flow control devices is mainly to control the fluid flow through the relative movement between the stopper rod and the sealing surface. When the stopper rod is separated from the sealing surface, the fluid can flow freely through the valve. When it is necessary to reduce the flow or close the valve, the stopper rod is rotated or moved to contact or adhere to the sealing surface, thereby blocking or partially blocking the fluid flow.

[0003] The applicant's research revealed that most existing stopper rod flow control devices require manual operation for flow adjustment. This is not only cumbersome and inefficient, but also makes precise flow control difficult. Manual operation often relies on the operator's experience and judgment, making it susceptible to human error and resulting in unstable flow control. This fails to meet the stringent requirements of modern industrial production for high precision and efficiency. Furthermore, manually operated stopper rod flow control devices pose safety hazards. In production environments requiring frequent flow adjustments, operators are frequently exposed to high-temperature, high-pressure, or corrosive fluids, increasing operational risks and potentially threatening their health.

[0004] Therefore, the applicant proposes an automatic pipe stopper flow control device to solve the problem. Utility Model Content

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0014] Depend on Figures 1-6 An automatic stopper rod flow control device for pipelines is provided, comprising a fluid tank 1, an outlet 11 installed at the bottom of the fluid tank 1, the inlet of the outlet 11 being conical and adapted to the bottom end of the stopper rod body 12, i.e., the lower end of the stopper rod body 12 is also conical. The upper end of the stopper rod body 12 is sealed and slides through the fluid tank 1 and is fixedly connected to a drive block 13. The drive block 13 is connected to a drive unit 2, which includes two vertical plates 20 fixed to the top of the fluid tank 1. A guide rod 21 and a rotatably mounted screw 22 are fixed between the vertical plates 20. The screw 22 is threadedly connected to a protrusion on the side of the drive frame 24, while the guide rod 21 is slidably connected to a protrusion on the other side of the drive frame 24. Inclined drive grooves 25 are provided on both sides inside the drive frame 24. A cylindrical block 26 is slidably connected inside the drive groove 25 and fixed on both sides of the drive block 13. A motor 23 is installed on the side wall of one of the vertical plates 20 for driving the screw 22 to rotate.

[0015] With the design of the drive unit 2 described above, the angle of the drive chute 25 is relatively small and the length is sufficient, typically 5-10 degrees. During flow regulation, the motor 23 drives the lead screw 22 to rotate, causing the drive frame 24 to move slowly at the limit of the guide rod 21. The cylindrical block 26 can only move up and down. Therefore, the inclined surface of the drive chute 25 pushes the cylindrical block 26 to move vertically, and the connected drive block 13 and stopper rod body 12 also move up and down. As the stopper rod body 12 moves up and down within the conical outlet 11, the fluid outflow channel... The flow rate is precisely adjusted so that when the stopper body 12 is fully or partially inserted into the outlet 11, the fluid flow rate decreases, and when the stopper body 12 is lifted upward and leaves the outlet 11, the fluid flow rate increases. Furthermore, since the angle of the drive chute 25 is designed to be small (5-10 degrees), it means that when the drive frame 24 moves horizontally by the same distance, the vertical movement distance of the cylindrical block 26 is more subtle. This design allows for precise control of the position of the stopper body 12 by fine-tuning the position of the drive frame 24, thereby improving the accuracy of flow rate adjustment.

[0016] A ring of sponge pad can be glued to the bottom of the drive frame 24. The sponge pad can contact the top surface of the fluid tank 1. A dustproof frame 210 is placed on the top of the drive frame 24. Insert rods 211 are fixed on the four sides of the top of the drive frame 24 and are inserted from the bottom holes of the dustproof frame 210.

[0017] Since the working environment of this device is typically dusty, a ring of sponge pads adhered to the bottom of the drive frame 24 effectively prevents dust from entering through the gap between the drive frame and the top surface of the fluid tank. The sponge pads are soft and elastic, allowing them to fit tightly against the top surface of the fluid tank, forming an effective dust barrier. Furthermore, the dust baffle 210, placed abutting the top of the drive frame 24, further enhances the dustproof effect. The dust baffle 210 cleverly surrounds the top of the drive frame, effectively blocking dust falling from above. Simultaneously, the insertion hole at the bottom of the dust baffle 210 fits tightly with the insertion rod 211 fixed to the top of the drive frame 214, ensuring a secure connection between the dust baffle and the drive frame. Rubber pads 27 are glued to both sides of the drive frame 24, and the rubber pads 27 are designed to be flame-retardant and pressure-resistant.

[0018] When the two sides of the drive frame 24 are in contact with the vertical plate 20, the stopper body 12 moves to the highest or lowest position. Therefore, the rubber pad 27 can play a good role in preventing collisions.

[0019] An index rod 28 is fixed to the outer wall of the side protrusion of the drive frame 24. A height scale 29 is provided below the index rod 28. The height scale 29 is installed on the top of the fluid tank 1. The index rod 28 is located close to the side of the height scale 29. Note that the parameters on the height scale 29 are flow parameters.

[0020] Furthermore, in terms of optimizing adjustment accuracy, the indicator rod 28 and height scale 29 are designed so that the indicator rod 28 moves back and forth as the drive frame 24 moves. When adjusting the flow rate, the operator only needs to adjust the drive of the motor 23 according to the production requirements and the scale on the height scale 29 to move the indicator rod 28 to the corresponding position, thereby achieving precise control of the fluid flow rate. This simplifies the operation process, improves work efficiency, and enhances the accuracy and stability of flow rate adjustment.

[0021] The four sides of the drive block 13 are connected by four guide rods 14, which together form a sliding connection, and the top of the four guide rods 14 is fixed with a square plate 15.

[0022] In terms of stability optimization, the sliding connection design formed by the four guide rods 14 passing through the four sides of the drive block 13 greatly enhances the stability of the drive block 13 during vertical movement. This ensures that the drive block 13 can move smoothly and without deviation along the axis of the guide rods 14 when subjected to driving force, thereby avoiding adjustment errors caused by shaking or tilting, or damage to the cylinder and stopper rod. The square plate 15, as a stable support structure, firmly connects the four guide rods 14 together, forming a stable frame.
