Description

Technical Field

[0001] The present invention relates to the technical field of solenoid valves, and in particular to a nested intelligent flow regulating solenoid valve. Background Art

[0002] In waterway or pipe installations, solenoid valves connecting parallel pipelines and controlling flow typically require the following accessories: The solenoid valve itself, the core component for on / off control, requires unions or flanges at both ends for quick assembly and disassembly. Filters are installed before and after the valve to prevent impurities from clogging the valve core. A flow meter or pressure gauge may be used to monitor flow and pressure. If flow regulation is required, a manual regulating valve can be added in parallel with the solenoid valve. To protect the piping system, a check valve prevents backflow. For long pipelines or large pressure fluctuations, a buffer tank or pressure stabilizer is required. Flexible connectors such as bellows absorb vibration, while brackets and clamps secure the pipeline. These accessories work together to ensure stable operation of the solenoid valve when opening or closing the pipeline, while also achieving precise flow control. The specific valve type should be determined based on the media characteristics, pressure level, and operating requirements.

[0003] Authorization publication number CN223037206U discloses a phase-shifting water level measurement device for a pumped-storage unit. The device, along with its specification and accompanying drawings, includes a high-water-level connecting pipe, a low-water-level connecting pipe, a first connecting pipe, a second connecting pipe, a real-time liquid level measuring device, and a tuning fork switch for outputting a liquid level switching signal. Specifically, the first and second connecting pipes are installed vertically side by side. To ensure secure mounting, pipe clamps can be welded to the walls of the first and second connecting pipes.

[0004] However, there are still certain limitations in this solution: 1. The flow control between the parallel first connecting pipe and the second connecting pipe or between the two series pipes can only be achieved after connecting with an ordinary solenoid valve using a flexible joint or a flange. At this time, due to the large number of parts, any damage to one of them will affect the uncontrollable flow of the entire pipeline, which brings inconvenience during use; 2. How to achieve flow control between the first connecting pipe and the second connecting pipe while meeting low costs or facilitating subsequent maintenance is also a problem that needs to be considered; 3. How to prevent water leakage at the water outlet after power failure is also a problem that needs to be considered. Summary of the Invention

[0005] The present invention mainly addresses the problems existing in flow control and regulation between pipelines, and invents a nested intelligent flow regulation solenoid valve. The second water channel of this solution is nested in the first water channel and fixed by a channel support plate.

This integrated, modular long channel design avoids the joints, flanges, brackets, clamps, etc. required for traditional multi-section pipeline connections.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The second water channel is nested within the first water channel and secured by a channel support plate. The first and second water channels can be lengthened according to flow control requirements. This integrated, modular long channel design avoids the joints, flanges, brackets, and clamps required for traditional multi-section pipe connections. This design greatly simplifies the system structure, reduces potential leak points, and improves the stability and reliability of the entire flow control valve during long-term use. Furthermore, the modular design facilitates production and installation expansion, achieving the beneficial effects of "simplifying the structure," "reducing the number of parts," and "improving system stability." 2. The aperture of the second water inlet nut is three times that of the first water inlet nut, which can achieve a three-fold flow relationship; An intelligent control system independently controls the opening and closing of each first and second valve core components, dynamically opening the second water inlet nuts of different apertures and the central through-hole of the first water inlet nut. This design enables fine flow adjustment (by combining multiple small-aperture nuts) or rapid response to high flow demands (by opening the large-aperture nut), meeting fluctuating water supply demands while optimizing energy consumption (by avoiding premature full opening of the large aperture). This step-by-step, intelligent flow regulation solution, utilizing a combination of nuts with different apertures, provides higher control accuracy and a wider flow adjustment range. 3. The arrangement of the first horizontal through hole and the first vertical through hole can ensure rapid pressure balance even after the coil is powered off, ensuring that the first iron core quickly resets and closes, avoiding seal failure due to residual pressure, and thus effectively extending the service life of the first iron core. 4. The water flow in the waterway gap can enter the top of the second seal through the membrane through-hole until it flows into the interior of the second horizontal through-hole and the second vertical through-hole of the second iron core, until it gradually fills the interior of the second valve body channel and the second spring limit groove, thereby balancing the pressure and filling these areas. The pressure in the waterway gap is equal to the pressure above the seal and is greater than the internal low pressure of the second waterway channel. After the support spring deforms to cause the sealing plug body to close the rivet through-hole, the pressure difference strongly presses the second seal against the through-hole of the second water inlet nut. This design, which uses the system's own water pressure to assist in enhancing the sealing force in the closed state, is an ingenious passive enhancement mechanism that significantly improves the closing sealing performance under large flow (large aperture) conditions, solves the problem of higher sealing force requirements for large-aperture valves, and embodies creativity and significant results.

DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: like Figure 1 、 Figure 2 and Figure 3 As shown, a nested intelligent flow regulating solenoid valve includes a first waterway channel 1 and a second waterway channel 2. The second waterway channel 2 is nested inside the first waterway channel 1. A waterway gap 10 is formed between the first waterway channel 1 and the second waterway channel 2. The second waterway channel 2 is provided with a plurality of water inlets capable of flowing water from the waterway gap 10 into the interior of the second waterway channel 2. The first waterway channel 1 is provided with a water inlet interface 5 and a water outlet interface 6 at both ends. One end of the water inlet interface 5 is threadedly connected to an external pipeline, and the other end of the water inlet interface 5 is connected to the waterway gap 10. One end of the water outlet interface 6 is threadedly connected to an external pipeline, and the other end of the water outlet interface 6 is connected to the second waterway channel 2. The second waterway channel 2 is nested inside the first waterway channel 1 via a channel support plate 7.

[0020] When the water flow rate at the end of the pipeline needs to be controlled, one end of the water inlet interface 5 can be threadedly connected to the end of the pipeline, and one end of the water outlet interface 6 can be threadedly connected to another pipeline. During the water flow process, water from the external pipeline flows from the inside of the water inlet interface 5 into the inside of the waterway gap 10. At this time, the number of open or closed water inlets on the surface of the second waterway channel 2 determines the flow rate entering the interior of the second waterway channel 2 from the waterway gap 10. Therefore, effectively controlling the opening or closing of the water inlets on the surface of the waterway channel 2 can effectively achieve water flow control for the water outlet interface 6.

[0021] Please continue to refer to Figure 3 The first water channel 1 is provided with a plurality of water valve mechanisms 3 capable of blocking or opening the water inlet. A first water inlet nut 21 or a second water inlet nut 22 is threadedly connected to the water inlet of each second water channel 2. The through-holes in the middle of the first and second water inlet nuts 21, 22 have different diameters, and the water valve mechanisms 3 are capable of blocking or opening the through-holes in the middle of the first and second water inlet nuts 21, 22.

[0022] Since the water valve mechanism 3 frequently opens or closes the through holes in the middle of the first water inlet nut 21 and the second water inlet nut 22, the through holes are inevitably worn to varying degrees. Therefore, the first water inlet nut 21 and the second water inlet nut 22 are detachably provided with threads, so that any damaged part can be replaced.

[0023] The diameters of the central through-holes of the first water inlet nut 21 and the second water inlet nut 22 are different. Generally, the flow rate of the central through-hole of the second water inlet nut 22 can be set to three times the flow rate of the central through-hole of the first water inlet nut 21. When the flow rate after opening the central through-holes of the two first water inlet nuts 21 cannot meet the water supply demand, the central through-hole of one second water inlet nut 22 can be opened while the two first water inlet nuts 21 are closed at the same time. Then, when the water supply demand increases, the first water inlet nut 21 is opened first. If the water supply demand cannot be met subsequently, the next second water inlet nut 22 is opened until the central through-holes of all the first water inlet nuts 21 and second water inlet nuts 22 are fully opened.

[0024] Therefore, users can configure different numbers of first and second water inlet nuts 21, 22 according to their needs and intelligently adjust the coordination between the first and second water inlet nuts 21, 22 to meet different water supply flow requirements. Of course, users can also lengthen the first and second water channels 1, 2 as required, thereby eliminating the need for joints, flanges, brackets, and clamps between the pipes, reducing the number of installed parts, and improving the control effect of the entire intelligent flow valve and its stability during long-term use.

[0025] Please continue to refer to Figure 4 and Figure 7 The surface of the first water channel 1 is provided with several first threaded holes 11 of different sizes. The water valve mechanism 3 includes a first valve core component 31 and a second valve core component 32. The interior of each first threaded hole 11 is threadedly installed with a first valve core component 31 or a second valve core component 32. The first valve core component 31 and the second valve core component 32 are respectively used to control whether the through holes in the middle of the first water inlet nut 21 and the second water inlet nut 22 are conductive.

[0026] The first seal 310 on the first valve core assembly 31 and the second seal 320 on the second valve core assembly 32 have different sizes. The first valve core assembly 31 is used to control whether the first seal 310 blocks the through hole in the middle of the first water inlet nut 21, and the second valve core assembly 32 is used to control whether the second seal 320 blocks the through hole in the middle of the second water inlet nut 22.

[0027] Since each first valve core assembly 31 and the second valve core assembly 32 are key components for controlling the conduction or blockage of the central through hole of each first water inlet nut 21 and the second water inlet nut 22, the detachable design between the first valve core assembly 31 and the second valve core assembly 32 and the first threaded hole 11 enables any subsequent first valve core assembly 31 or second valve core assembly 32 to be individually repaired and replaced when it is damaged, avoiding the need to replace the entire flow control valve.

[0028] Please continue to refer to Figure 4 and Figure 5 Each of the first valve core components 31 includes a first valve body 311, a first iron core 312, a first return spring 314 and a first sealing member 310. The first valve body 311 is connected to the inside of the first threaded hole 11 by a threaded manner. A first valve body channel 315 is provided inside the first valve body 311, and the first iron core 312 is slidably connected to the inside of the first valve body channel 315. A first return spring 314 is provided between the first spring limiting groove 313 inside the first iron core 312 and the top of the first valve body channel 315. A first sealing member 310 is detachably installed inside the end of the first iron core 312. The first sealing member 310 is a cylindrical plug body. The first valve body 311 is provided with a detachable coil 4 on the outside. When the first iron core 312 slides relative to the first valve body channel 315, it can control whether the first sealing member 310 blocks the through hole in the middle of the first water inlet nut 21. The first vertical through hole 317 is vertically arranged relative to the first sealing member 310 and the first vertical through hole 317 extends from the first spring limiting groove 313 to the first plug body mounting groove 318.

[0029] With this arrangement, when the coil 4 is energized, the first iron core 312 can slide upward. As the first iron core 312 slides upward in the first valve body channel 315, the first return spring 314 is continuously squeezed and deformed. Simultaneously, the first sealing member 310 and the through-hole in the middle of the first water inlet nut 21 gradually open, allowing water in the waterway gap 10 to flow into the interior of the second waterway channel 2 through the through-hole in the middle of the first water inlet nut 21.

[0030] When the coil 4 is powered off, the first iron core 312 slides downward inside the first valve body channel 315 under the elastic reaction force of the first return spring 314 until the first seal 310 gradually fits into the through hole in the middle of the first water inlet nut 21. At this time, the water in the waterway gap 10 cannot flow into the through hole in the middle of the first water inlet nut 21.

[0031] The end of the first core 312 is provided with a first plug mounting groove 318, within which the first seal 310 is removably mounted. This arrangement is due to the fact that the first core 312 is a metal component and therefore cannot effectively block the through-hole in the center of the first water inlet nut 21. The first seal 310 is a silicone component with a certain degree of deformation, thus effectively blocking the through-hole in the center of the first water inlet nut 21. Furthermore, since the first seal 310 is frequently squeezed during use, this removable design also facilitates subsequent maintenance and reduces maintenance costs.

[0032] Please continue to refer to Figure 4 and Figure 8 The interior of the first iron core 312 is also provided with a first horizontal through hole 316 and a first vertical through hole 317 for balancing the water pressure in the first valve body channel 315. The first horizontal through hole 316 is arranged horizontally compared to the first seal 310 and the first horizontal through hole 316 passes through the side wall of the first iron core 312.

[0033] As the first seal 310 at the bottom of the first iron core 312 gradually fits against the through-hole in the middle of the first water inlet nut 21, water in the waterway gap 10 flows in from the first horizontal through-hole 316 and gradually fills the first valve body channel 315 and the first spring retaining groove 313 through the first vertical through-hole 317, thereby balancing the pressure. This ensures that the first iron core 312 inside the first valve body 311 is not affected by the water pressure in the first waterway channel 1, allowing the first iron core 312 to slide more smoothly.

[0034] Without the first horizontal through hole 316 and the first vertical through hole 317, since there is no water and air inside the second water channel 2, the pressure in the second water channel 2 and the water channel gap 10 are not equal. As a result, the first iron core 312 will be affected by the siphon pressure or water pressure during the sliding process from bottom to top, making it difficult to move upward. Therefore, the provision of the first horizontal through hole 316 and the first vertical through hole 317 can ensure rapid pressure balance even after the coil 4 is powered off, ensuring that the first iron core 312 quickly resets and closes, avoiding seal failure due to residual pressure, and thus effectively increasing the service life of the first iron core 312.

[0035] The setting of the first horizontal through hole 316 and the first vertical through hole 317 can also ensure that excess gas can be discharged when the first seal 310 is installed into the interior of the first plug body installation groove 318, ensuring that the first seal 310 can fit into the interior of the first plug body installation groove 318, thereby improving installation accuracy.

[0036] The first core 312 is provided with a first annular boss 319 extending outward from above the first horizontal through hole 316. Since the first core 312 slides within the first valve body channel 315, to prevent the inner wall of the first valve body channel 315 from blocking the end opening of the first horizontal through hole 316, the first annular boss 319 is designed so that when the first core 312 slides upward to its highest point, a gap remains between the first core 312 and the interior of the first valve body channel 315, ensuring that water in the waterway gap 10 can smoothly enter the first horizontal through hole 316 through this gap.

[0037] Please continue to refer to Figure 4 、 Figure 6 and Figure 9 The second valve core assembly 32 includes a second valve body 321, a second iron core 323, a second return spring 325 and a second sealing member 320. The second valve body 321 is connected to the inside of the first threaded hole 11 by a threaded manner. A second valve body channel 322 is provided inside the second valve body 321, and a second iron core 323 is slidably connected to the inside of the second valve body channel 322. A second return spring 325 is provided between the second spring limiting groove 324 inside the second iron core 323 and the top of the second valve body channel 322. The end of the second iron core 323 is connected to the second sealing member 320 through a support spring 326. When the second iron core 323 slides compared to the second valve body channel 322, it can control whether the second sealing member 320 blocks the through hole in the middle of the second water inlet nut 22.

[0038] The second valve body 321 is provided with a detachable coil 4 on the outside. When the second valve body 321 slides relative to the second valve body channel 322, the second sealing member 320 can be controlled by the support spring 326 to block the through hole in the middle of the first water inlet nut 21.

[0039] With this arrangement, when the coil 4 is energized, the second iron core 323 can slide upward. As the second iron core 323 slides upward in the second valve body channel 322, the second return spring 325 is continuously squeezed and deformed. Simultaneously, the second sealing member 320 and the through-hole in the middle of the second water inlet nut 22 gradually open, allowing water in the waterway gap 10 to flow into the interior of the second waterway channel 2 through the through-hole in the middle of the second water inlet nut 22.

[0040] When the coil 4 is powered off, the second iron core 323 slides downward inside the second valve body channel 322 under the elastic reaction force of the second return spring 325 until the second seal 320 at the end of the support spring 326 gradually fits into the through hole in the middle of the second water inlet nut 22. At this time, the water in the waterway gap 10 cannot flow into the through hole in the middle of the second water inlet nut 22.

[0041] Similarly, the second iron core 323 is a metal component, so it cannot effectively block the through hole in the middle of the second water inlet nut 22. The second sealing member 320 is a sheet-like film with a certain deformation ability, so it can effectively block the through hole in the middle of the second water inlet nut 22.

[0042] In this embodiment, a second plug mounting groove is provided at the end of the second iron core 323 , and a sealing plug 3231 is provided inside the second plug mounting groove. The height of the support spring 326 becomes lower after being subjected to force, so that the sealing plug 3231 can block the rivet through hole 3205 .

[0043] In this embodiment, the interior of the second iron core 323 is further provided with a second horizontal through hole 327 and a second vertical through hole 328 for balancing the water pressure in the second valve body channel 322. The second horizontal through hole 327 is horizontally arranged compared to the second sealing member 320 and the second horizontal through hole 327 passes through the side wall of the second iron core 323. The second vertical through hole 328 is vertically arranged compared to the second sealing member 320. The second vertical through hole 328 passes from the second spring limiting groove 324 to the second plug body mounting groove.

[0044] A film through hole 3201 is also provided on the surface of the second seal 320, and a first clamping iron sheet 3202 is provided on the surface of the second seal 320. A metal rivet 3203 is connected to the first clamping iron sheet 3202 and the middle of the second seal 320. A second clamping iron sheet 3204 is provided between the bottom of the metal rivet 3203 and the bottom of the second seal 320. A spring retaining ring 3232 is provided at the top of the metal rivet 3203 and the end of the second iron core 323. The support spring 326 is clamped on the adjacent spring retaining ring 3232. A rivet through hole 3205 is provided in the middle of the metal rivet 3203.

[0045] During the process of the second iron core 323 sliding downward in the second valve body channel 322: First, the water in the waterway gap 10 flows through the membrane through-hole 3201 and into the upper portion of the second sealing member 320. The water then enters the second horizontal through-hole 327 and the second vertical through-hole 328, gradually filling the second valve body channel 322 and the second spring retaining groove 324, thereby balancing the pressure. This ensures that the second iron core 323 within the second valve body 321 is not affected by the water pressure in the first waterway channel 1, allowing the second iron core 323 to slide more smoothly.

[0046] During this process, the second core 323 drives the support spring 326 via the spring retaining ring 3232. The support spring 326, in turn, drives the metal rivet 3203, the second pressing iron sheet 3204, the first pressing iron sheet 3202, and the second sealing member 320 downward via the spring retaining ring 3232 at the top of the metal rivet 3203. As the second sealing member 320 gradually fits into the through hole in the middle of the second water inlet nut 22, the support spring 326 deforms, allowing the sealing plug 3231 at the end of the second core 323 to block the rivet through hole 3205 of the metal rivet 3203. At the moment when the rivet through hole 3205 is blocked, the internal pressure of the second water channel 2 becomes low, and the water pressure in the water gap 10 in the first water channel 1 is greater than that inside the second water channel 2. The water in the water gap 10 flows into the top of the second sealing member 320 through the film through hole 3201 to balance the pressure, so that the pressure in the water gap 10 is equal to the pressure above the second sealing member 320, and both are greater than that inside the second water channel 2. Therefore, this pressure can firmly fit the second sealing member 320 to the through hole in the middle of the second water inlet nut 22.

[0047] Without the provision of the film through hole 3201, the second horizontal through hole 327, and the second vertical through hole 328, since there is no water and air inside the second waterway channel 2, the pressure in the second waterway channel 2 and the waterway gap 10 are not equal. As a result, the second iron core 323 will be affected by the siphon pressure or water pressure during the sliding process from bottom to top, making it difficult to move upward. Therefore, the provision of the film through hole 3201, the second horizontal through hole 327, and the second vertical through hole 328 can ensure rapid pressure balance even after the coil 4 is powered off, ensuring that the second iron core 323 quickly resets and closes, avoiding sealing failure due to residual pressure, and based on this, can effectively increase the service life of the second iron core 323.

[0048] The through-hole structure of membrane through-hole 3201, second horizontal through-hole 327, and second vertical through-hole 328, in conjunction with support spring 326, creates a damping effect that cushions fluid impact and prevents vibration or water hammer caused by excessive movement of second core 323. By connecting the upper and lower regions of second seal 320, membrane through-hole 3201 eliminates the water pressure difference between the upper and lower layers of second core 323, enabling smooth movement of second core 323 under the action of electromagnetic force.

[0049] When the electromagnet is powered off, the film through hole 3201, the second horizontal through hole 327 and the second vertical through hole 328 assist the medium to quickly balance the pressure, ensuring that the second iron core 323 is quickly reset and closed under the action of the second reset spring 325, avoiding improper sealing due to residual pressure.

[0050] The second core 323 is provided with a second annular boss 329 extending outward from above the second horizontal through hole 327. Since the second core 323 slides within the second valve body channel 322, to prevent the inner wall of the second valve body channel 322 from blocking the end opening of the second horizontal through hole 327, the second annular boss 329 is designed so that when the second core 323 slides upward to its highest point, a gap remains between the second core 323 and the interior of the second valve body channel 322, ensuring that water in the waterway gap 10 can smoothly enter the second horizontal through hole 327 through this gap.

[0051] Working principle and usage of the present invention: If the outflow rate at the end of the pipeline needs to be controlled, one end of the water inlet interface 5 can be threadedly connected to the end of the pipeline, and one end of the water outlet interface 6 can be threadedly connected to another pipeline. During the water flow process, water from the external pipeline flows from the inside of the water inlet interface 5 into the waterway gap 10. At this time, the number of openings or closings in the middle of the first water inlet nut 21 and the second water inlet nut 22 on the second waterway channel 2 determines the amount of flow entering the second waterway channel 2 from the waterway gap 10.

[0052] The first valve core assembly 31 and the second valve core assembly 32 control the opening or closing of the through hole in the middle of each first water inlet nut 21 and each second water inlet nut 22 to effectively control the water outflow of the water outlet interface 6.

[0053] Regarding the first valve core assembly 31 controlling the opening or closing of the through-hole in the middle of the first water inlet nut 21, when the coil 4 is energized, the first iron core 312 can slide upward. As the first iron core 312 slides upward within the first valve body passage 315, the first return spring 314 is continuously squeezed and deformed. Simultaneously, the first sealing member 310 and the through-hole in the middle of the first water inlet nut 21 gradually open, allowing water within the waterway gap 10 to flow through the through-hole in the middle of the first water inlet nut 21 into the interior of the second waterway passage 2.

[0054] When the coil 4 is powered off, the first iron core 312 slides downward inside the first valve body channel 315 under the elastic reaction force of the first return spring 314 until the first seal 310 gradually fits into the through hole in the middle of the first water inlet nut 21. At this time, the water in the waterway gap 10 cannot flow into the through hole in the middle of the first water inlet nut 21.

[0055] Regarding the second valve core assembly 32 controlling the opening or closing of the through-hole in the middle of the second water inlet nut 22, when the coil 4 is energized, the second iron core 323 slides upward. As the second iron core 323 slides upward in the second valve body passage 322, the second return spring 325 is continuously squeezed and deformed. Simultaneously, the second sealing member 320 and the through-hole in the middle of the second water inlet nut 22 gradually open, allowing water within the waterway gap 10 to flow into the interior of the second waterway passage 2 through the through-hole in the middle of the second water inlet nut 22.

[0056] When the coil 4 is powered off, the second iron core 323 slides downward inside the second valve body channel 322 under the elastic reaction force of the second return spring 325 until the second seal 320 at the end of the support spring 326 gradually fits into the through hole in the middle of the second water inlet nut 22. At this time, the water in the waterway gap 10 cannot flow into the through hole in the middle of the second water inlet nut 22.

Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
