A flow regulator

Abstract

This utility model relates to a flow regulator, including a flow control plate and an adjustment plate. The flow control plate has a spiral groove, and its inner or outer edge is set as an adjustment edge. The radius of the adjustment edge changes, causing the width of the spiral groove to gradually increase along its extension trajectory. The adjustment plate has a water outlet. The adjustment plate and the flow control plate can rotate relative to each other. During rotation, the flow area formed by the water outlet and the adjustment edge of the spiral groove gradually increases or decreases, achieving stepless adjustment between 0 and the maximum flow rate. During the adjustment process, as the adjustment plate rotates relative to the flow control plate, the cooperation relationship between the water outlet and the adjustment edge of the spiral groove changes, thereby changing the size of the flow area and achieving smooth flow regulation.

Description

Technical Field

[0001] This utility model relates to the field of fluid flow control equipment technology, specifically a flow regulator. Background Technology

[0002] In fluid transport systems, the need for precise flow control is widespread. Traditional flow regulators typically operate on a stepped control mode, making it difficult to achieve stepless smooth control from 0 to maximum flow. Their limited control accuracy fails to meet the demands of scenarios requiring high flow control precision. Therefore, it is necessary to design new flow regulators to address this issue. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art by providing a flow regulator that enables precise stepless adjustment of fluid flow, thus meeting the needs of high-precision flow control scenarios.

[0004] The technical solution of this utility model is: a flow regulator, including a flow control plate and an adjustment plate stacked thereon;

[0005] The flow control plate is provided with a spiral groove, and its inner or outer edge is set as an adjustment edge. The radius of the adjustment edge changes so that the width of the spiral groove gradually increases along its extension trajectory.

[0006] The regulating plate is provided with a water inlet hole. The regulating plate and the flow control plate can rotate relative to each other and are positioned coaxially. During the rotation, the flow area formed by the water inlet hole and the spiral groove regulating edge gradually increases or decreases, realizing stepless adjustment between 0 and the maximum flow rate.

[0007] By adopting the above technical solution, this utility model can achieve precise stepless adjustment of fluid flow rate. During the adjustment process, as the adjusting plate rotates relative to the flow control plate, the fit between the inlet hole and the adjusting edge of the spiral groove changes, thereby altering the size of the flow passage area. This design not only achieves stepless flow rate adjustment but also ensures a continuous and smooth adjustment process, avoiding the sudden flow changes that may occur during the adjustment process of traditional throttling valves. This improves the stability and accuracy of flow control, meeting the needs of high-precision flow control scenarios. Furthermore, the coaxial positioning of the adjusting plate and the flow control plate prevents offset caused by the back-and-forth rotation of the adjusting plate.

[0008] A further feature of this invention is that the width of the water inlet hole is less than or equal to the maximum width of the spiral groove.

[0009] By adopting the above further settings, it can be ensured that the flow area can reach its maximum, thereby realizing the maximum adjustment range of the flow rate.

[0010] A further feature of this invention includes a rotary control device that drives the adjusting plate to rotate. The rotary control device and the adjusting plate cooperate to form a water inlet cavity, and the water inlet cavity is connected to the water outlet and the water inlet.

[0011] With the aforementioned further design, the rotary control acts as the driving component, precisely controlling the rotation of the regulating vane, thereby achieving accurate flow regulation. The inlet chamber design ensures smooth water flow into and out of the outlet. The entire process is efficient and smooth, greatly improving water utilization and regulation efficiency.

[0012] A further feature of this invention is that the water outlet is located on the side wall of the adjusting plate or the rotary control and is arranged in an oblique hole shape.

[0013] With the above-mentioned further design, the oblique-shaped water outlet allows the water to flow out of the inlet chamber in a smoother manner, reducing the impact and turbulence of the water flow, thereby reducing noise generation.

[0014] A further improvement of this invention is that the water outlet has multiple holes.

[0015] By employing the aforementioned further design, the multiple water outlets can more effectively disperse the water flow, avoiding uneven pressure and unstable flow caused by excessively concentrated water flow. Simultaneously, multiple water outlets also improve water output efficiency, ensuring a rapid and uniform flow, further enhancing water utilization and adjustment precision.

[0016] A further feature of this invention is that the rotary control and the adjusting plate rotate synchronously through the interlocking of protrusions and grooves.

[0017] With the above-mentioned further design, the interlocking structure of the protrusion and groove ensures a tight connection and synchronous rotation between the rotary control and the adjustment plate.

[0018] A further feature of this invention is that the adjusting plate and the flow control plate are both sleeved on the same rotating shaft, and the center of the adjusting plate and the flow control plate is provided with a shaft hole for the rotating shaft to pass through.

[0019] The aforementioned further design, with the shaft hole through which the rotating shaft passes, ensures the positioning of the adjusting plate and the flow control plate, allowing the adjusting plate to rotate smoothly and accurately, thereby achieving fine adjustment of the water flow and preventing it from deviating due to back-and-forth rotation.

[0026] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figure 1-6 As shown, a flow regulator of this utility model includes a flow control plate 1 and an adjustment plate 2 stacked on it. The flow control plate 1 and the adjustment plate 2 are stacked vertically or horizontally.

[0028] The flow control plate 1 is provided with a spiral groove 11, and the inner edge or outer edge of the spiral groove is provided as an adjustment edge 111. The radius of the adjustment edge 111 changes so that the width of the spiral groove 11 gradually increases along its extension trajectory. The inner edge of the spiral groove 11 is provided as the adjustment edge 111, and its inner edge extends inward. The outer edge of the spiral groove 11 is provided as the adjustment edge 111, and its outer edge extends outward.

[0029] The adjusting plate 2 is provided with a water inlet hole 21. The adjusting plate 2 and the flow control plate 1 can rotate relative to each other and are coaxially positioned. Both the adjusting plate 2 and the flow control plate 1 are sleeved on the same rotating shaft 5. The center of the adjusting plate 2 and the flow control plate 1 is provided with a shaft hole c for the rotating shaft to pass through. During rotation, the flow area a (i.e., the overlapping and communicating area of ​​the water inlet hole 21 and the spiral groove adjusting edge 111) formed by the water inlet hole 21 and the spiral groove gradually increases or decreases, realizing stepless adjustment between 0 and the maximum flow rate. The width of the water inlet hole 21 is less than or equal to the maximum width of the spiral groove 11.

[0030] Specifically, it also includes a rotary control 3 that drives the adjustment plate 2 to rotate. The rotary control 3 cooperates with the adjustment plate 2 to form a water inlet cavity b, which communicates with the water outlet b1 and the water inlet 21. The water outlet b1 is located on the side wall of the adjustment plate 2 or the rotary control 3 and is arranged in an oblique hole shape. There are multiple water outlets b1. Of course, the water outlet b1 can also be located on the upper part of the rotary control 3. The water inlet 21 is located at the bottom of the water inlet cavity b.

[0031] The rotary control 3 and the adjusting plate 2 rotate synchronously through the mating of the protrusion 41 and the groove 42. Furthermore, the connection method between the rotary control 3 and the adjusting plate 2 is not limited to the mating of the protrusion 41 and the groove 42; other methods such as screw connection can also be used to adapt to different application scenarios and installation requirements. The rotary control 3 and the adjusting plate 2 can also be installed as a single unit.

[0032] The working principle of this utility model:

[0033] In use, the control plate 2 is rotated relative to the flow control plate 1 by rotating the control plate 3, which changes the fit between the water inlet 21 and the spiral groove adjustment edge 111, thereby changing the size of the flow passage area a. When the flow rate is increased from 0, the water inlet slowly rotates from one side of the adjustment edge into the corresponding area of ​​the spiral groove. At this time, the overlapping and connecting area with the spiral groove, i.e., the flow passage area, gradually increases, and the fluid flow rate also increases smoothly. Conversely, when the control plate rotates in the opposite direction, the water inlet slowly moves away from the corresponding area of ​​the spiral groove, and after it is completely offset, the flow rate is 0.

[0034] As the flow area a increases or decreases, the flow rate is also smoothly adjusted accordingly. Water flows from the flow area a into the inlet chamber b and flows out quickly and evenly from multiple oblique outlet holes b1.

[0035] like Figure 5 As shown, when the outer edge of the spiral groove 11 is set as the adjusting edge 111, when the water inlet rotates, the inner edge of the water inlet is aligned with or offset from the outer edge of the spiral groove, which can completely block the flow.

[0036] It should be noted that in the description of this utility model, all directional indicators (such as up, down, forward, backward, etc.) are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "installation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
