Description

Technical Field

[0001] This utility model relates to the field of flow control valve technology, specifically to a flow control valve that can filter media. Background Technology

[0002] Flow control valves are crucial for regulating flow and reducing pressure in water supply systems. Their core function is to precisely control the fluid flow area by changing the valve opening, thereby achieving stable flow regulation. Flow control valves are widely used in many water supply projects, especially in the environmental water treatment processes of chemical plants, where they play a vital role. Currently, flow control valves utilize a multi-orifice structure deep within their interior to spray water. This design, through a multi-level orifice array, forms a multi-stage energy dissipation structure. The flow guide device at each orifice outlet causes the fluid to collide, effectively reducing the velocity and energy of the medium. Simultaneously, the gap between the inner guide tube and the outer shell forms an annular channel, which, combined with the multi-orifice design, streamlines the medium's movement, ensuring stable flow control characteristics during regulation.

[0003] According to patent publication number CN211951486U, a valve for easy filtration is disclosed, comprising a telescopic rod, a sliding rod, a piston ring, a sleeve, a spring, a float, an inlet pipe, an outlet pipe, a threaded pipe, a connecting pipe, an annular baffle, a rubber ring, an arc-shaped baffle, a T-shaped groove, a main filter screen, a T-shaped rubber block, a guide hole, a guide hopper, a threaded valve stem, an opening and closing baffle, a guide pipe, a collection cylinder, a secondary filter screen, and a valve body. This invention allows for better filtration of impurities in flowing water during operation, causing the filtered impurities to settle in the collection cylinder. This significantly improves the valve's working efficiency and functionality while also greatly saving costs. It also allows for easier disassembly and assembly of the main and secondary filter screens, making operation more convenient and facilitating cleaning, greatly reducing the workload of operators and enhancing the valve's practicality.

[0004] The existing technology has the following problems: In the aforementioned publication, a filter screen is used to filter impurities from the water flow. However, because the filter screen is round and has a flat surface, impurities easily accumulate when they come into contact with the water, causing the filter screen to clog quickly and shortening its service life. Furthermore, cleaning the filter screen requires a series of operations: disassembling the screen, cleaning the adhered impurities, and then reinstalling it. This process is not only laborious and cumbersome, but also affects operational efficiency, making the entire process inconvenient.

[0005] Therefore, we need a flow control valve that can filter media to solve the above problems. Utility Model Content

[0006] This invention provides a flow regulating valve that can filter media, in order to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A flow regulating valve for filtering media includes a flow regulating valve, a connecting component on the left side of the outer surface of the flow regulating valve, a discharge port with internal and external communication on the lower left side of the outer surface of the flow regulating valve, a filter component installed on the left side of the interior of the flow regulating valve, positioning posts fixedly connected to the corners of the lower outer surface of the flow regulating valve near the discharge port, the interior of the discharge port corresponding to the outer surface of the filter component, the filter component including a mounting ring, the outer surface of the mounting ring being fixedly connected to the inner wall of the flow regulating valve, a conical filter screen on the left side of the mounting ring, a circular handle fixedly connected to the middle left side of the conical filter screen, and a cleaning component fixedly connected to the lower outer surface of the conical filter screen.

[0009] A further improvement of this utility model is that the fixing plate and the wire brush are in an inclined state.

[0010] A further improvement of this utility model is that: an annular anti-detachment groove is opened in the middle of the inner wall of the mounting ring, a rotating ring is fixedly connected to the right end face of the conical filter screen, and an anti-detachment ring is fixedly connected to the outer surface of the rotating ring.

[0011] A further improvement of this utility model is that the outer surface of the rotating ring is movably connected to the interior of the mounting ring, and the outer surface of the anti-detachment ring is movably connected to the interior of the annular anti-detachment groove.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: This invention provides a flow regulating valve for filtering media. It uses a conical filter screen to intercept impurities in the water flow. The conical shape allows water to easily wash away impurities in the center, causing them to slide outwards and keeping the center clear, thus improving filtration efficiency.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Example 1: As Figures 1 to 5 As shown, this utility model provides a flow regulating valve for filtering media, including a flow regulating valve 1. The flow regulating valve 1 serves as the main structure and plays a core role in regulating fluid flow. The connecting component 2 on the left side of its outer surface is used to seal the flow regulating valve 1 when water is being transported, preventing water from leaking out of the outlet 11. The outlet 11, which is open to the inside and outside on the lower left side of the outer surface of the flow regulating valve 1, is used to discharge impurities intercepted by the filter component 3, preventing impurities from accumulating inside the flow regulating valve 1 and affecting fluid flow. This also makes it easier for workers to reach inside and rotate the filter component 3 for subsequent cleaning.

[0021] A positioning post 12, fixedly connected to the lower outer surface of the flow regulating valve 1 near the corner of the outlet 11, provides a positioning reference for the installation of the connecting assembly 2, ensuring that the connecting assembly 2 can be installed on the flow regulating valve 1, and enhancing the stability of the connection between the connecting assembly 2 and the flow regulating valve 1. The filter assembly 3, installed on the left side inside the flow regulating valve 1, filters the water flowing into the flow regulating valve 1, intercepting impurities in the water and preventing impurities from entering the spray structure inside the flow regulating valve 1, ensuring the normal operation of the flow regulating valve 1. The interior of the outlet 11 corresponds to the outer surface of the filter assembly 3. Example 2: Figures 1 to 5 As shown, the filter assembly 3 includes a mounting ring 31, the outer surface of which is fixedly connected to the inner wall of the flow regulating valve 1, providing stable and fixed positioning for the entire filter assembly. The conical filter screen 32 located on the left side of the mounting ring 31 employs a conical structure design, allowing impurities on the central surface to slide outwards during water flow, keeping the center free of impurities and reducing their accumulation in the middle of the filter screen. A circular handle 33 is fixedly connected to the center of the left side of the conical filter screen 32, facilitating gripping and rotation by the operator to drive the conical filter screen 32 to rotate. The annular anti-detachment groove 301, which is opened in the middle of the inner wall of the mounting ring 31, works in conjunction with the rotating ring 302 and the anti-detachment ring 303, which are fixedly connected to the right end face of the conical filter screen 32, to facilitate rotation inside the mounting ring 31.

[0022] The outer surface of the rotating ring 302 is movably connected to the interior of the mounting ring 31, causing the conical filter screen 32 to rotate, thus cleaning impurities from the filter screen surface for subsequent cleaning components; the outer surface of the anti-detachment ring 303 is movably connected to the interior of the annular anti-detachment groove 301, preventing the conical filter screen 32 from falling off the mounting ring 31 and ensuring the structural integrity of the filter assembly 3. A cleaning component is fixedly connected below the outer surface of the conical filter screen 32. This component is used to clean impurities adhering to the outer surface of the conical filter screen 32, preventing impurities from clogging the filter screen holes and affecting the filtration effect. The cleaning component includes a fixing block 36, which provides mounting support for a fixing plate 34. The fixing plate 34 is fixedly connected above the outer surface of the fixing block 36. A wire brush 35 is fixedly connected to the outer surface of the fixing plate 34 near the conical filter screen 32. Its outer surface contacts and engages with the outer surface of the conical filter screen 32. When the conical filter screen 32 rotates, the wire brush 35 can clean the impurities on the filter screen surface, brushing the adhering impurities off to the discharge port 11 for discharge. The fixing plate 34 and the wire brush 35 are in an inclined state. The angle of this inclined surface is adapted to the angle of the conical surface of the conical filter screen 32, ensuring that the wire brush 35 can fully contact the filter screen surface and improve the cleaning effect. The fixing bolt 37, which is movably connected, passes through the middle of the left side of the fixing block 36. Its outer surface passes through the internal thread of the mounting ring 31. The cleaning component is fixed on the mounting ring 31 by the fixing bolt 37 to prevent the cleaning component from shifting and to ensure the cleaning component can be disassembled and replaced later. Example 3: Figures 1 to 5 As shown, the connecting component 2 includes an annular ring 21. The outer surface of the annular ring 21 is fitted onto the outer surface of the flow regulating valve 1. The gap formed between the inner side of the annular ring 21 and the outer surface of the flow regulating valve 1 facilitates the up-and-down movement of the annular ring 21. A threaded fixing bolt 22 passes through the upper part of the outer surface of the annular ring 21, and a protective plate 23 is fixedly connected to its lower end. Tightening the fixing bolt 22 can drive the protective plate 23 to move downward, so that the lower surface of the protective plate 23 is tightly fitted against the outer surface of the flow regulating valve 1. When the protective plate 23 contacts the flow regulating valve 1, the annular ring 21 moves upward as the fixing bolt 22 is continuously tightened, so that the inner side of the subsequent arc-shaped rubber plate 25 is in close contact with the outer surface of the flow regulating valve 1, thereby achieving a sealing effect. The protective plate 23 prevents the fixing bolt 22 from damaging the surface of the flow regulating valve 1 during tight contact. An arc-shaped fixing plate 24 is fixedly connected to the lower inner side of the annular ring 21. An arc-shaped rubber plate 25 is fixedly connected to the inner side of the arc-shaped fixing plate 24 by adhesive bonding. The adhesive bonding method facilitates the replacement of the arc-shaped rubber plate 25 after aging. The arc-shaped structure matches the curvature of the outer surface of the flow regulating valve 1, enhancing the fit between the connecting component 2 and the flow regulating valve 1. The arc-shaped rubber plate 25 is elastic; when the annular ring 21 moves upward, the inner side of the arc-shaped rubber plate 25 contacts and compresses the flow regulating valve 1, causing the arc-shaped rubber plate 25 to compress and contract, ensuring a tight seal between the arc-shaped rubber plate 25 and the surface of the flow regulating valve 1. Both the arc-shaped rubber plate 25 and the arc-shaped fixing plate 24 have vertically connected positioning holes 26 at their inner corners. These holes are inserted into the outer surface of the positioning post 12. The cooperation between the positioning holes 26 and the positioning post 12 ensures precise positioning of the connecting component 2 on the flow regulating valve 1, preventing rotation of the connecting component 2 during installation and ensuring the stability of the annular ring 21 during installation. Working Principle: During use, the unique design of the conical filter screen 32 effectively facilitates the filtration of impurities in the water flow. Its conical shape effectively prevents impurities from accumulating in the middle of the filter screen, ensuring that impurities slide to the periphery under the action of water flow, thereby improving filtration efficiency. When it is necessary to clean the impurities intercepted by the conical filter screen 32, first close the main valve of the pipeline to cut off the water supply. Next, the worker rotates and removes the fixing bolt 22, and then moves the annular ring 21 downwards so that its inner upper side contacts the surface of the flow regulating valve 1. At this time, the positioning hole 26 separates from the positioning post 12. Then, the connecting assembly 2 is moved to the left to expose the discharge port 11, making it easier for the worker to clean the impurities. The worker puts his hand into the discharge port 11, grasps the circular handle 33 and rotates it, causing the conical filter screen 32, the rotating ring 302, and the anti-detachment ring 303 to rotate within the mounting ring 31. At the same time, the steel wire brush 35 is used to clean the impurities around the filter screen, so that the cleaned impurities are discharged from the discharge port 11. After cleaning, move the connecting component 2 so that the positioning hole 26 aligns with the positioning post 12, and tighten the fixing bolt 22 so that the protective plate 23 contacts the flow regulating valve 1. Continue to tighten the fixing bolt 22, and the annular ring 21 moves upward, so that the inner side of the arc-shaped rubber plate 25 makes tight contact with the surface of the flow regulating valve 1, achieving a seal. Finally, open the main valve to restore water supply.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
