Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a synchronous dual-circuit control valve structure. Background Art

[0002] In water systems, the flow of water can be controlled by opening and closing valves. For example, in a household water pipe, when a certain part needs to be repaired, the corresponding valve can be closed to cut off the water flow and prevent water leakage and loss.

[0003] In some scenarios, one water channel needs to be opened while another water channel needs to be closed. In this case, two valve bodies are usually required for control, which not only increases the complexity, but also the synchronization of the water channel switches cannot be guaranteed. Utility Model Content

[0004] The embodiment of the utility model aims to provide a synchronous dual-way control valve structure, aiming to solve at least one of the technical problems existing in the prior art.

[0005] The present invention solves the technical problem by adopting the following technical solutions:

[0013] The push rod assembly can slide into the first hydraulic chamber to block the first pressure relief hole; or can slide into the second hydraulic chamber to block the second pressure relief hole.

[0014] In some embodiments, the push rod assembly includes an iron core and a winding wound around the iron core. When the winding is energized, a magnetic field can be generated to control the iron core to move up and down.

[0015] In some embodiments, a first pressing plate is provided on one side of the first elastic tympanic membrane close to the top rod assembly, and the top rod assembly can apply a force to the first elastic tympanic membrane through the first pressing plate to prevent a portion of the first elastic tympanic membrane from separating from the first water outlet.

[0016] In some embodiments, a second pressing plate is provided on one side of the second elastic tympanic membrane close to the top rod assembly, and the top rod assembly can apply a force to the second elastic tympanic membrane through the second pressing plate to prevent part of the second elastic tympanic membrane from separating from the second water outlet.

[0017] In some embodiments, the iron core includes a main body and a rod, and the rod is provided at both ends of the main body;

[0018] In an initial state, one of the rods is located in the first hydraulic chamber, and the other rod can slide into the second hydraulic chamber to block the second pressure relief hole; or

[0019] One of the rods is located in the second hydraulic chamber, and the other rod can slide into the first hydraulic chamber to block the first pressure relief hole.

[0020] In some embodiments, the partitions are provided with through holes, wherein one of the rods can pass through the through hole on the upper partition to enter the first cavity, and the other rod can pass through the through hole on the lower partition to enter the second cavity;

[0021] Wherein, a sealing ring is provided in the through hole, and the sealing ring is tightly fitted to the outer side of the rod portion to prevent water from flowing into the third cavity through the through hole.

[0023] In some embodiments, the push rod assembly further comprises an elastic member;

[0024] One end of the elastic member is connected to the main body, and the other end is connected to one of the partitions;

[0025] When the winding is energized, the elastic member may be compressed or expanded to accumulate elastic potential energy, and then restored to its original state when the winding is de-energized to drive the iron core back to its initial position.

[0026] In some embodiments, the push rod assembly further comprises a magnet, and at least one of the two partitions is provided with the magnet;

[0027] When the winding is de-energized, the magnet close to the iron core can generate an adsorption force on the iron core to restrict the movement of the iron core.

In this case, the second water outlet on the second chamber is opened, allowing the waterway in the second chamber to be opened. Alternatively, the push rod assembly can reside within the second chamber, isolating the second water inlet from the second water outlet. In this case, the first water outlet on the third chamber is opened, allowing the waterway in the first chamber to be opened. Furthermore, the push rod assembly can be moved from the first chamber to the second chamber, thereby closing the waterway in the first chamber and opening the waterway in the second chamber. Alternatively, the push rod assembly can be moved from the second chamber to the first chamber, thereby closing the waterway in the second chamber and opening the waterway in the first chamber. This arrangement reduces the number of components and installation complexity compared to using two separate valve bodies. Only one synchronous dual-circuit control valve structure needs to be installed and operated, eliminating the need for two separate valves. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art in the field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0040] The following combination Figures 1 to 6 , the synchronous dual-way control valve structure 100 provided in the embodiment of the present application is described in detail through specific embodiments.

[0041] Please also refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 This is a structural diagram of the synchronous dual-way control valve structure provided by the utility model; Figure 2 This is a structural schematic diagram from another angle of the synchronous dual-way control valve structure provided by the utility model; Figure 3 It is a cross-sectional schematic diagram of the synchronous two-way control valve structure provided by the present invention. The synchronous two-way control valve structure 100 provided in one embodiment of the present invention includes a tube body 10, a partition 20 and a push rod assembly 30. The openings at both ends of the tube body 10 extend into the tube body 10 to form a first water outlet 14 and a second water outlet 15; the two partitions 20 are arranged on the tube body 10 from top to bottom to divide the interior of the tube body 10 into a first cavity 11, a second cavity 12 and a third cavity 13. The first cavity 11 is provided with a first water inlet 111, and the second cavity 12 is provided with a second water inlet 121; the push rod assembly 30 is slidably arranged in the third cavity 13. The push rod assembly 30 can slide into the first cavity 11 to isolate the first water inlet 111 from the first water outlet 14; or can slide into the second cavity 12 to isolate the second water inlet 121 from the second water outlet 15.

[0042] The partitions 20 are provided on the tube body 10, and the tube body 10 is divided into a first cavity 11, a second cavity 12, and a third cavity 13, which are isolated from each other. In addition, through holes 21 may be provided on the two partitions 20, so that the ejector assembly 30 located in the third cavity 13 can move through the through holes 21 into the first cavity 11 or the second cavity 12.

[0043] The tube body 10 is provided with a first water inlet 111 and a second water inlet 121. The first water inlet 111 is in communication with the first cavity 11, and the second water inlet 121 is in communication with the second cavity 12. The first water inlet 111 and the second water inlet 121 can both be connected to an external water source, so that the external water source enters the first cavity 11 through the first water inlet 111, and the external water source enters the second cavity 12 through the second water inlet 121.

[0044] The push rod assembly 30 is slidably positioned within the third cavity 13. In an initial state, one end of the push rod assembly 30 is positioned within the first cavity 11 or the second cavity 12, and the other end is positioned within the third cavity 13. When one end of the push rod assembly 30 is positioned within the first cavity 11 in the initial state, the push rod assembly 30 isolates the first water inlet 111 and the first water outlet 14 from each other, thereby closing the water path within the first cavity 11. When one end of the push rod assembly 30 is positioned within the second cavity 12 in the initial state, the push rod assembly 30 isolates the second water inlet 121 and the second water outlet 15 from each other, thereby closing the water path within the second cavity 12.

[0045] In this embodiment, the push rod assembly 30 is arranged in the third cavity 13. In the initial state, one end of the push rod assembly 30 can be naturally located in the first cavity 11 to isolate the first water inlet 111 from the first water outlet 14. At this time, the second water outlet 15 on the second cavity 12 is opened, and the water path on the second cavity 12 can be opened; or it can be located in the second cavity 12 to isolate the second water inlet 121 from the second water outlet 15. At this time, the first water outlet 14 on the third cavity is opened, and the water path on the first cavity 11 can be opened. And by moving the push rod assembly 30, the push rod assembly 30 can be moved from the first cavity 11 to the second cavity 12, thereby closing the water path of the first cavity 11 and opening the water path of the second cavity 12; or by moving the push rod assembly 30 from the second cavity 12 to the first cavity 11, thereby closing the water path of the second cavity 12 and opening the water path of the first cavity 11. Through this configuration, the synchronized dual-circuit control valve structure 100 reduces the number of components and installation complexity compared to using two independent valve bodies. Only one synchronized dual-circuit control valve structure 100 needs to be installed and operated, eliminating the need for two independent valves. For example, in a small domestic hot water supply system with two cold water inlets (e.g., a mixed supply of water from different temperature sources), the use of this synchronized dual-circuit control valve structure 100 can make the entire system more concise and reduce the clutter of pipes. Furthermore, because the same push rod assembly 30 controls the opening and closing of both waterways, excellent synchronization can be ensured. Whether operated manually or through automated control (e.g., connected to an electric drive device), simply controlling the movement of the push rod assembly 30 ensures that the opening and closing actions of the two waterways are executed at the same time. In industrial applications where high synchronization of water flow switching is required, such as the precise feed control of two raw materials in chemical production (assuming the raw materials are transported via waterways), production accidents or product quality issues caused by asynchrony can be avoided.

[0046] In some embodiments, the first elastic tympanic membrane 40 and the second elastic tympanic membrane 50 are further included; the first elastic tympanic membrane 40 is disposed in the first cavity 11 and abuts against the first water outlet 14 to separate the first cavity 11 into a first water inlet cavity 112 and a first water pressure cavity 113, the first water inlet cavity 112 is connected to the first water pressure cavity 113 through a first pressure-increasing hole 41 provided on the first elastic tympanic membrane 40, and the first water pressure cavity 113 is connected to the first water outlet 14 through a first pressure-relieving hole 42 provided on the first elastic tympanic membrane 40; the second elastic tympanic membrane 50 is disposed in the second The cavity 12 is in contact with the second water outlet 15 to separate the second cavity 12 into a second water inlet chamber 122 and a second water pressure chamber 123. The second water inlet chamber 122 is connected to the second water pressure chamber 123 through a second pressurization hole 51 provided on the second elastic tympanic membrane 50. The second water pressure chamber 123 is connected to the second water outlet 15 through a second pressure relief hole 52 provided on the second elastic tympanic membrane 50. The push rod assembly 30 can slide into the first water pressure chamber 113 to block the first pressure relief hole 42; or can slide into the second water pressure chamber 123 to block the second pressure relief hole 52.

[0047] When one end of the push rod assembly 30 is located within the first hydraulic chamber 113 and blocks the first pressure relief hole 42, water enters the first water inlet chamber 112 from the first water inlet 111 and then enters the first hydraulic chamber 113 through the first pressure-increasing hole 41. Since the first pressure relief hole 42 is now blocked by the push rod assembly 30, water cannot flow through the first pressure relief hole 42 into the first water outlet 14. The water pressure within the first hydraulic chamber 113 increases to a certain extent, and the water pressure within the first hydraulic chamber 113 exerts a force toward the first elastic tympanic membrane 40, thereby causing the first elastic tympanic membrane 40 to adhere tightly to the first water outlet 14. With this arrangement, the water path of the first chamber 11 is closed. Then, when the push rod assembly 30 moves into the second hydraulic chamber 123, the first pressure relief hole 42 opens. At this time, water can flow into the first water outlet 14 through the first pressure relief hole 42, the water pressure in the first hydraulic chamber 113 decreases, and the water pressure in the first water inlet chamber 112 increases. The water pressure in the first water inlet chamber 112 can exert a force toward the first elastic tympanic membrane 40, thereby separating the first elastic tympanic membrane 40 from the first water inlet 111. The water in the first water inlet chamber 112 can flow directly to the first water inlet 111 and out through the first water inlet 111. When one end of the push rod assembly 30 is located in the second hydraulic chamber 123 and blocks the second pressure relief hole 52, its working principle is the same as the above-mentioned principle of the push rod assembly 30, and will not be repeated here. Through this arrangement, the push rod assembly 30 can be used to control the on-off of the water channels in the first cavity 11 and the second cavity 12, and good synchronization can be ensured.

[0048] In some embodiments, the top rod assembly 30 includes an iron core 31 and a winding 32 wound around the iron core 31. When the winding 32 is energized, a magnetic field can be generated to control the iron core 31 to move up and down. Its specific electromagnetic induction structure and principle are existing technologies and will not be elaborated here.

[0049] By controlling the magnitude and direction of the current in the winding 32, the moving position of the iron core 31 can be precisely controlled. Compared with mechanical drive methods (such as manual operation or simple mechanical connecting rod drive), electromagnetic drive can achieve more subtle adjustments. And electromagnetic drive has a fast response characteristic. When it is necessary to change the on-off state of the water path in the first cavity 11 and the second cavity 12 in the synchronous two-way control valve structure 100, the change in current can almost instantly generate a corresponding magnetic field change on the iron core 31, thereby causing the iron core 31 to move quickly.

[0050] Specifically, according to Ampere's law, when current passes through the winding 32, a magnetic field is generated around the iron core 31. For a solenoid-shaped winding 32, if you hold the solenoid with your right hand and let your four fingers point to the direction of the current in the solenoid, then the direction pointed by your thumb is the direction of the magnetic field inside the solenoid. For example, if the winding 32 is wound clockwise, when current flows into one end of the winding 32, the direction of the generated magnetic field can be determined according to the right-hand screw rule. At this time, when the iron core 31 is in this magnetic field, it will be magnetized because the iron core 31 is a magnetic material. Magnetized objects in the magnetic field are affected by the magnetic field force. At this time, if the direction of the current is changed, according to the right-hand screw rule, the direction of the generated magnetic field will also change. For example, the direction of the magnetic field generated by the clockwise current is upward, and when the current changes to counterclockwise flow, the direction of the magnetic field changes to downward.

[0051] When the direction of the magnetic field changes, the direction of the magnetic force acting on the iron core 31 also changes. The direction of the magnetic force controls whether the iron core 31 moves upward or downward. In the synchronous dual-way control valve structure 100, the iron core 31 can move upward (toward the first hydraulic chamber 113) when the current flows in the forward direction, and downward (toward the second hydraulic chamber 123) when the current flows in the reverse direction.

[0052] In some embodiments, a first pressing plate 60 is provided on one side of the first elastic tympanic membrane 40 close to the top rod assembly 30. The top rod assembly 30 can apply a force to the first elastic tympanic membrane 40 through the first pressing plate 60 to prevent part of the first elastic tympanic membrane 40 from separating from the first water outlet 14.

[0053] When the push rod assembly 30 is within the first cavity 11, it always maintains contact with the first pressing plate 60, thereby exerting a contact force on the first pressing plate 60. When the water path within the first cavity 11 of the synchronous dual-way control valve structure 100 is normally closed, the first elastic tympanic membrane 40 maintains contact with the first water outlet 14 under the action of water pressure, preventing the first water outlet 14 from communicating with the first water inlet cavity 112. At this time, the first pressing plate 60 is close to the first elastic tympanic membrane 40 and contacts the first elastic tympanic membrane 40, exerting pressure on the first elastic tympanic membrane 40, thereby ensuring that the first elastic tympanic membrane 40 always maintains contact with the first water outlet 14.

[0054] When pressure fluctuations, water hammer phenomena, or other conditions that may cause uneven force on the first elastic tympanic membrane 40 occur in the first cavity 11, the first pressing plate 60 begins to function. For example, when a sudden increase in water pressure impacts the first elastic tympanic membrane 40, the first elastic tympanic membrane 40 may have a tendency to partially separate from the first water outlet 14. At this time, if the push rod assembly 30 is in a position close to the first elastic tympanic membrane 40, the push rod assembly 30 will apply additional pressure to the first elastic tympanic membrane 40 through the first pressing plate 60. This pressure can be perpendicular to the surface of the first elastic tympanic membrane 40 and toward the first water outlet 14, thereby ensuring that the first elastic tympanic membrane 40 is in close contact with the first water outlet 14 and preventing the two from separating. Through such a setting, the cooperation between the first pressing plate 60 and the push rod assembly 30 ensures a tight connection between the first elastic tympanic membrane 40 and the first water outlet 14, maintains good sealing performance, and effectively prevents leakage problems caused by the separation of the first elastic tympanic membrane 40 from the water outlet.

[0055] A small hole may be provided on the first pressing plate 60 , and the position of the small hole corresponds to the position of the first pressure relief hole 42 on the first elastic tympanic membrane 40 , so that when the push rod assembly 30 moves away from the first elastic tympanic membrane 40 , water can flow through the small hole and the first pressure relief hole 42 in sequence to the first water outlet 14 , thereby adjusting the pressure in the first water pressure chamber 113 .

[0056] In some embodiments, a second pressing plate 70 is provided on one side of the second elastic tympanic membrane 50 close to the top rod assembly 30. The top rod assembly 30 can apply a force to the second elastic tympanic membrane 50 through the second pressing plate 70 to prevent part of the second elastic tympanic membrane 50 from separating from the second water outlet 15.

[0057] When the push rod assembly 30 is within the second cavity 12, it always maintains contact with the second pressing plate 70, thereby generating a contact force on the second pressing plate 70. When the water path within the second cavity 12 of the synchronous two-way control valve structure 100 is normally closed, the second elastic tympanic membrane 50 maintains contact with the second water outlet 15 under the action of water pressure, preventing the second water outlet 15 from communicating with the second water inlet cavity 122. At this time, the second pressing plate 70 is close to and in contact with the second elastic tympanic membrane 50, exerting pressure on the second elastic tympanic membrane 50, thereby ensuring that the second elastic tympanic membrane 50 always maintains contact with the second water outlet 15.

[0058] When pressure fluctuations, water hammer, or other conditions that may cause uneven force on the second elastic tympanic membrane 50 occur within the second cavity 12, the second pressing plate 70 begins to function. For example, when a sudden increase in water pressure impacts the second elastic tympanic membrane 50, it may cause the second elastic tympanic membrane 50 to partially separate from the second water outlet 15. At this time, if the push rod assembly 30 is located near the second elastic tympanic membrane 50, the push rod assembly 30 will apply two additional pressures to the second elastic tympanic membrane 50 through the second pressing plate 70. This pressure can be perpendicular to the surface of the second elastic tympanic membrane 50 and toward the second water outlet 15, thereby ensuring that the second elastic tympanic membrane 50 is in close contact with the second water outlet 15 and preventing the two from separating. Through this arrangement, the cooperation between the second pressing plate 70 and the push rod assembly 30 ensures a tight connection between the second elastic tympanic membrane 50 and the second water outlet 15, maintains good sealing performance, and effectively prevents leakage problems caused by the second elastic tympanic membrane 50 separating from the water outlet.

[0059] A small hole may be provided on the second pressing plate 70 , and the position of the small hole corresponds to the position of the second pressure relief hole 52 on the second elastic tympanic membrane 50 , so that when the push rod assembly 30 is away from the second elastic tympanic membrane 50 , water can flow through the small hole and the second pressure relief hole 52 in sequence to the second water outlet 15 , thereby adjusting the pressure in the second water pressure chamber 123 .

[0060] In some embodiments, the iron core 31 includes a main body 312 and a rod 311. The rod 311 is arranged at both ends of the main body 312. In the initial state, one of the rods 311 is located in the first hydraulic chamber 113, and the other rod 311 can slide into the second hydraulic chamber 123 to block the second pressure relief hole 52; or one of the rods 311 is located in the second hydraulic chamber 123, and the other rod 311 can slide into the first hydraulic chamber 113 to block the first pressure relief hole 42.

[0061] The main body 312 is slidably positioned within the third cavity 13. In the initial state, when one of the rods 311 is positioned within the first cavity 11 and blocks the first pressure relief hole 42, the other rod 311 and the main body 312 are positioned within the third cavity 13. Water enters the first water inlet cavity 112 from the first water inlet 111 and then enters the first hydraulic cavity 113 through the first pressurization hole 41. Because the first pressure relief hole 42 is now blocked by the push rod assembly 30, water cannot flow through the first pressure relief hole 42 into the first water outlet 14. The water pressure within the first hydraulic cavity 113 increases to a certain extent, and the water pressure within the first hydraulic cavity 113 exerts a force on the first elastic tympanic membrane 40, thereby causing the first elastic tympanic membrane 40 to adhere tightly to the first water outlet 14. With this arrangement, the water path within the first cavity 11 is closed.

[0062] When the winding 32 is energized, the main body 312 can be controlled to move downward. At this time, the rod portion 311 located in the first cavity 11 gradually moves away from the first cavity 11 and enters the third cavity 13. The other rod portion 311 gradually approaches the second cavity 12 and moves to block the second pressure relief hole 52. At this time, the first pressure relief hole 42 is opened, and water can flow into the first water outlet 14 through the first pressure relief hole 42. The water pressure in the first water pressure chamber 113 decreases, and the water pressure in the first water inlet chamber 112 increases. The water pressure in the first water inlet chamber 112 can exert a force on the first elastic tympanic membrane 40, thereby separating the first elastic tympanic membrane 40 from the first water inlet 111. The water in the first water inlet chamber 112 can flow directly to the first water inlet 111 and out through the first water inlet 111. The second pressure relief hole 52 is blocked by the other rod portion 311. Water enters the second water inlet chamber 122 from the second water inlet 121, and then enters the second hydraulic chamber 123 through the second pressurizing hole 51. Because the second pressure relief hole 52 is now blocked by the other rod portion 311, water cannot flow through the second pressure relief hole 52 into the second water outlet 15. The water pressure within the second hydraulic chamber 123 increases to a certain extent, and the water pressure within the second hydraulic chamber 123 exerts a force on the second elastic tympanic membrane 50, causing it to adhere tightly to the second water outlet 15. This arrangement closes the water path of the second chamber 12.

[0063] Through the above arrangement, without using two valves, when the water path in the first cavity 11 is opened, the water path in the second cavity 12 can be closed synchronously; or when the water path in the second cavity 12 is opened, the water path in the first cavity 11 can be closed synchronously.

[0064] In some embodiments, a through hole 21 is provided on the partition 20, wherein one rod portion 311 can pass through the through hole 21 located on the upper partition 20 to enter the first cavity 11, and the other rod portion 311 can pass through the through hole 21 located on the lower partition 20 to enter the second cavity 12; wherein, a sealing ring 211 is provided in the through hole 21, and the sealing ring 211 fits tightly with the outer side of the rod portion 311 to prevent water from flowing through the through hole 21 into the third cavity 13.

[0065] When the iron core 31 moves, the rod portion 311 at its upper end moves toward the first cavity 11. The upper rod portion 311 enters the first cavity 11 through the through hole 21 of the upper partition 20; or the lower rod portion 311 moves toward the second cavity 12, and the lower rod portion 311 enters the second cavity 12 through the through hole 21 of the lower partition 20. For example, when it is necessary to control the water circuit in the first cavity 11 to be closed, the upper rod portion 311 moves and passes through the through hole 21 to enter the first cavity 11 to block the first pressure relief hole 42; when it is necessary to control the water circuit in the second cavity 12 to be closed, the lower rod portion 311 moves and passes through the through hole 21 to enter the second cavity 12 to block the second pressure relief hole 52.

[0066] During the process of the rod 311 passing through the through hole 21, the sealing ring 211 in the through hole 21 fits tightly against the outside of the rod 311. Due to this tight fit, when there is water in the first cavity 11 or the second cavity 12, the water cannot enter the third cavity 13 through the gap between the rod 311 and the through hole 21. Even under a certain water pressure, the sealing ring 211 can prevent the penetration of water. If water enters the third cavity 13, it may cause an electrical short circuit, corrode the iron core 31 and the winding 32, and render the electromagnetic drive function ineffective. Through such a setting, the winding 32 and the iron core 31 in the third cavity 13 can be effectively protected. In addition, when water enters the third cavity 13, it will affect the water pressure in the first water pressure chamber 113 and the second water pressure chamber 123.

[0067] In some embodiments, a silicone cap 313 is provided at the top of the rod 311, and the silicone cap 313 is adapted to the through hole 21 and the first pressure relief hole 42 and the second pressure relief hole 52. The silicone cap 313 is adapted to the first pressure relief hole 42 and the second pressure relief hole 52, and can provide better sealing performance when blocking. The silicone material has good flexibility and elasticity, and can fit tightly to the edge of the pressure relief hole, effectively preventing water from leaking through the tiny gap between the first pressure relief hole 42 or the second pressure relief hole 52 and the rod 311. Compared with relying on the rod 311 for blocking, the silicone cap 313 can better adapt to the irregular shape or uneven surface of the pressure relief hole, further improve the water flow cutoff effect, and reduce the amount of leakage.

[0068] Furthermore, the silicone cap 313 can fill the small gap between the rod 311 and the through hole 21, preventing water from entering the third cavity 13 through the through hole 21. This can protect the electrical components (such as the iron core 31 and the winding 32) in the third cavity 13 from corrosion or short circuit.

[0069] In some embodiments, the top rod assembly 30 also includes an elastic member 314; one end of the elastic member 314 is connected to the main body 312, and the other end is connected to one of the partitions 20; when the winding 32 is energized, the elastic member 314 can be compressed or expanded to accumulate elastic potential energy, and then when the winding 32 is de-energized, it can be restored to its original state to drive the iron core 31 back to its initial position.

[0070] See also Figure 4 and Figure 5 , Figure 4 This is a cross-sectional view of the structure of the synchronous dual-way control valve provided by the utility model; Figure 5 yes Figure 4 Enlarged schematic diagram at point A in the middle. In this embodiment, when the winding 32 is energized to generate a magnetic field, causing the iron core 31 to move to control the water flow, the iron core 31 can drive the elastic member 314 to move together. For example, in the initial state of the iron core 31, one of the rods 311 is located in the second hydraulic chamber 123 and blocks the second pressure relief hole 52. After the winding 32 is energized, the other rod 311 of the iron core 31 can move toward the first hydraulic chamber 113 and block the first pressure relief hole 42. At this time, the rod 311 in the second hydraulic chamber 123 is separated from the first pressure relief hole 42, the water path in the second chamber 12 is opened, the first pressure relief hole 42 is blocked, and the water path in the first chamber 11 is disconnected. During this process, the elastic member 314 connected to the iron core 31 will be stretched or compressed (depending on the installation method and initial state of the elastic member 314), and during this process, the elastic member 314 will accumulate elastic potential energy. When the winding 32 is de-energized and the magnetic field disappears, the elastic member 314 begins to release the elastic potential energy previously accumulated. Due to the effect of the elastic potential energy, the elastic member 314 returns to its original shape and length. This recovery process drives the iron core 31 back to its initial position. As a result, the lower rod 311 returns to the second hydraulic chamber 123 and blocks the second pressure relief hole 52. The water path in the second cavity 12 is closed again, and the upper rod 311 moves away from the first hydraulic chamber 113, reopening the water path in the first cavity 11. This arrangement allows the iron core 31 to automatically reset without the need for additional energy to drive the iron core 31 to reset.

[0071] Specifically, the elastic member 314 may be installed between the upper partition plate 20 and the main body 312 of the iron core 31 , or between the lower partition plate 20 and the main body 312 of the iron core 31 .

[0072] It should be noted that the elastic member 314 can be a spring.

[0073] See also Figure 6 , Figure 6 This is a cross-sectional view of another embodiment of a synchronous dual-way control valve structure provided by the present invention. In some embodiments, the push rod assembly 30 further includes magnets 315, which are disposed on the two partitions 20. When the winding 32 is de-energized, the magnets 315 exert an attractive force on the iron core 31, thereby restricting its movement.

[0074] After the winding 32 is de-energized, the magnet 315 exerts an attractive force on the core 31, allowing the core 31 to remain in its current position, thereby maintaining the synchronous dual-way control valve structure 100 in the state it was in at the moment the power was turned off. For example, when the rod 311 of the core 31 is located within the first hydraulic chamber 113, after the winding 32 is de-energized, the magnet 315 of the upper partition 20 exerts an attractive force on the core 31, preventing the core 31 from moving downward. This ensures that the waterway in the first chamber 11 remains closed, while the waterway in the second chamber 12 remains open. When the rod 311 of the core 31 is located within the second hydraulic chamber 123, the magnet 315 of the lower partition 20 exerts an attractive force on the core 31, preventing the core 31 from moving upward. This ensures that the waterway in the second chamber 12 remains closed, while the waterway in the first chamber 11 remains open. This arrangement utilizes the attraction of magnet 315 to maintain the position of iron core 31, simplifying control of the valve's state after power is removed. After power is removed from winding 32, the synchronous dual-way control valve structure 100 self-locks, eliminating the need for constant current flow and reducing power consumption. It also eliminates the need for additional mechanical locking devices or complex control procedures to ensure the stability of the synchronous dual-way control valve structure 100 during power outages.

[0075] It should be noted in particular that the synchronous two-way control valve structure 100 provided in the embodiment of the present invention only shows the part related to the technical problem to be solved by the embodiment of the present invention. It can be understood that the synchronous two-way control valve structure 100 provided in the embodiment of the present invention also includes other structures for realizing the synchronous two-way control valve structure 100, including but not limited to pipes connected to the first water inlet and the second water inlet, pipes connected to the first water outlet and the second water outlet, etc.
