[0002] An electrically controlled valve is an automated valve device that controls the flow of fluid or regulates its flow rate using electrical signals. Its core functions include remote control, rapid response, and adaptability to various scenarios. Electrically controlled valves include solenoid valves with an electromagnetic coil as their core component. The end of the electromagnetic coil extends outward and connects to the control device. In existing solenoid valve manufacturing processes, the electromagnetic coil is encapsulated entirely using injection molding to eliminate gaps between the coil and the external components, thereby improving sealing.

[0003] However, the above-mentioned process for processing electromagnetic coils is complex, and the complex structure of electromagnetic coils leads to high manufacturing costs, especially when secondary encapsulation is required. Utility Model Content

[0004] The technical problem to be solved by this utility model is the high manufacturing cost of electromagnetic coils in electromagnetic valves. The purpose is to provide an electronically controlled regulating device and an electronically controlled valve to solve the above-mentioned problem.

[0005] This utility model is achieved through the following technical solution:

[0006] In a first aspect, this utility model provides an electronically controlled adjustment device, including a coil module and a yoke;

[0007] The coil module includes an electronically controlled coil, a coil frame, and a guide rod. The electronically controlled coil is wound around the outer circumferential surface of the coil frame. The guide rod is located at one end of the coil frame and is coaxially arranged with the coil frame to form an electronically controlled end. Correspondingly, the end of the electronically controlled coil extends to the guide rod.

[0008] The yoke connects to the coil module and is used for magnetic conduction.

[0009] In one possible design, the coil module also includes a wire cover;

[0010] One end of the coil frame is provided with a first groove for the extension of the guide rod;

[0011] The guide rod is connected to the coil frame through the beam. The beam is provided with a second groove that is adapted to the first groove. Accordingly, the first groove and the second groove form a wire groove.

[0012] The wire cover is placed over the wire trough and is used to protect the electrical control coil;

[0013] Accordingly, the end of the electronic control coil extends through the wire groove to the guide rod, so as to be connected to the electronic control component through the guide rod;

[0014] Accordingly, the yoke is connected to the end of the coil frame to press against the wire cover, beam and control coil, and the yoke is provided with a through hole adapted to the guide rod.

[0016] In one possible design, there are two first slots arranged opposite each other on both sides of the guide rod. Correspondingly, the electronic control coil has two ends, which are respectively inserted into one of the first slots and converge to the guide rod.

[0017] In one possible design, the beam body includes at least two L-shaped sub-beams, and several sub-beams are spaced apart on the same circumference with the guide rod as the center. Correspondingly, at least two sub-beams are provided with a second groove.

[0018] In one possible design, the end face of the coil frame is provided with a connecting part for connecting the yoke, and correspondingly, the yoke is provided with a matching connecting structure.

[0019] In one possible design, the end face of the coil frame is provided with an outwardly extending radial limiting part, which forms a snap-fit ​​groove for connecting the yoke.

[0020] In one possible design, the guide rod has a radial protrusion extending into the coil frame, which is used to connect other components.

[0021] In one possible design, the cover can be either a separate cover or a one-piece cover;

[0022] The split lid includes at least two lid bodies;

[0023] The integrated cover includes at least two cover bodies and a central ring for connecting multiple cover bodies. Accordingly, when the integrated cover is applied to the groove, the central ring is fitted onto the guide rod.

[0024] In one possible design, the yoke can be either a separate piece or a single piece;

[0025] The split plate includes at least two sub-plates, each of which is provided with a connecting structure. When the sub-plates are covered on the wire groove, a gap is left between adjacent sub-plates. Correspondingly, the guide rod passes through the gap, and the wire cover is located in the gap.

[0026] The integrated piece is provided with the through hole, the connection structure, and the mounting groove adapted to the wire cover.

[0027] In one possible design, the wire cover can be either a separate cover or a one-piece cover, and the yoke can be either a separate piece or a one-piece piece; correspondingly, when the wire cover is a separate cover, the yoke is a separate piece; when the wire cover is a one-piece cover, the yoke is a one-piece piece.

[0029] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0030] The end of the control coil extends to the control terminal, causing the ends of the control coil to converge. Simultaneously, a yoke is positioned at the control terminal of the coil module, covering the end of the control coil. Thus, the end of the control coil is fixed and protected by the yoke, eliminating the need for a molding process to improve sealing, reducing molding-related steps and equipment, and significantly lowering manufacturing costs.

[0031] The yoke cuts off the direct connection between the end of the electronic control coil and the outside world, preventing the end of the electronic control coil from being exposed, protecting and reducing wear on the end of the electronic control coil, thus making the electronic control valve with the electronic control regulating device have a longer service life and a lower failure rate during use.

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0040] Example:

[0041] like Figures 1-4 As shown, an electronically controlled regulating device includes a coil module 10 and a yoke 20;

[0042] The coil module 10 includes an electronically controlled coil 11, a coil frame 12, and a guide rod 13. The electronically controlled coil 11 is wound around the outer peripheral surface of the coil frame 12. The guide rod 13 is located at one end of the coil frame 12 and is coaxially arranged with the coil frame 12 to form an electronically controlled end. Correspondingly, the end of the electronically controlled coil 11 extends to the guide rod 13.

[0043] The yoke 20 is connected to the coil module 10 and is used for magnetic conduction.

[0044] In the described electronically controlled regulating device, the main body of the electronically controlled coil 11 is wound on the coil frame 12, and the end of the electronically controlled coil 11 extends to the electronically controlled end, causing the ends of the electronically controlled coil 11 to converge. Simultaneously, a yoke 20 is placed at the electronically controlled end of the coil module 10, covering the end of the electronically controlled coil 11. This disconnects the end of the electronically controlled coil 11 from the outside, preventing the end of the electronically controlled coil 11 from being exposed, protecting and reducing wear on the end of the electronically controlled coil 11, resulting in a longer service life and a lower failure rate for the electronically controlled valve in the regulating device.

[0045] It is noteworthy that the coil frame 12 is constructed to fit the shape of the electrically controlled valve, allowing the electrically controlled regulating device to move with the valve core, reducing movement obstruction. The coil module 10 is connected to the electrically controlled component via the guide rod 13. Any suitable existing component can be used to transmit control signals to the electrically controlled regulating device, and the electrically controlled valve operates according to the control signals. The yoke 20 also has a magnetic guiding function, guiding the magnetic lines of force of the electrically controlled coil 11 to form a closed loop, reducing magnetic energy loss and helping to improve the working efficiency of the coil module 10.

[0046] Based on this, in the electronic control adjustment device, the end of the electronic control coil 11 is fixed and protected by the yoke 20, eliminating the need for a plastic sealing process to improve sealing performance, reducing plastic sealing-related processes and equipment, and greatly reducing manufacturing costs.

[0047] It is easy to understand that the electronic control coil 11 can be any suitable existing electromagnetic coil.

[0048] The electronic control adjustment device will be further described below in conjunction with the structure of the coil module 10:

[0049] In one possible implementation, the coil module 10 also includes a wire cover 14;

[0050] One end of the coil frame 12 is provided with a first groove 101 extending from the guide rod 13;

[0051] The guide rod 13 is connected to the coil frame 12 through the beam 102. The beam 102 is provided with a second groove 103 adapted to the first groove 101. Accordingly, the first groove 101 and the second groove 103 form a wire groove.

[0052] The wire cover 14 is installed on the wire trough and is used to protect the electronic control coil 11;

[0053] Accordingly, the end of the electronic control coil 11 extends through the wire groove to the guide rod 13, so as to be connected to the electronic control component through the guide rod 13;

[0054] Correspondingly, the yoke 20 is connected to the end of the coil frame 12 to press against the wire cover 14, the beam 102 and the electric control coil 11, and the yoke 20 is provided with a through hole 201 adapted to the guide rod 13.

[0055] Based on the above design, for the guide rod 13, the end of the electronic control coil 11 extends to the guide rod 13 through a wire groove. The guide rod 13 also serves to converge and concentrate the end of the electronic control coil 11. At the same time, the wire groove is provided to further reduce the volume of the electronic control coil 11 exposed, especially the first groove 101. That is, when the end of the electronic control coil 11 moves from the outer peripheral surface of the coil frame 12 to the end face of the coil frame 12, the electronic control coil 11 will inevitably be exposed because it needs to cross the edge of the coil frame 12. The first groove 101 minimizes the exposed length to protect the electronic control coil 11.

[0056] Although the electronic control coil 11 is installed inside the wire groove, some of it may still protrude from the groove. To improve protection and enhance the wire management of the electronic control coil 11, a wire cover 14 is provided on the wire groove to cover the electronic control coil 11. The wire cover 14 also cooperates with the yoke 20 to further improve protection.

[0057] In one possible implementation, at least two first grooves 101 are provided and spaced apart on the end face of the coil frame 12; correspondingly, at least two second grooves 103 are provided on the beam 102.

[0058] Based on the above design scheme, for different types of coil windings, the control coil 11 has at least two ends. For example, the electromagnetic coil on a single-phase transformer winding has two ends, the electromagnetic coil on a tapped transformer has at least three ends, and the electromagnetic coil on a three-phase generator winding has six ends. Therefore, the number of first slots 101 is not less than two, and the specific number is determined according to the actual type of coil used.

[0059] Optionally, such as Figures 1-3 As shown, there are two first grooves 101 arranged opposite each other on both sides of the guide rod 13. Correspondingly, the electronic control coil 11 has two ends, which are respectively inserted into one of the first grooves 101 and converge to the guide rod 13.

[0060] In one possible implementation, the beam 102 includes at least two L-shaped sub-beams, and several sub-beams are spaced apart on the same circumference with the guide rod 13 as the center. Correspondingly, at least two sub-beams are provided with second grooves 103.

[0061] Based on the above design, one end of the sub-beam is connected to the coil frame 12, and the other end is connected to the guide rod 13. The sub-beam is L-shaped, thereby raising the guide rod 13 to increase the length of the guide rod 13 extending out of the yoke 20. The number of sub-beams can be flexibly selected, but should not be less than the number of first slots 101, to ensure that each first slot 101 is connected to the corresponding second slot 103, so as to form a number of slots not less than the number of ends of the electronic control coil 11, ensuring that the ends of the electronic control coil 11 are all inserted into a slot.

[0062] In one possible implementation, the end face of the coil frame 12 is provided with a connecting portion 104 for connecting the yoke 20, and correspondingly, the yoke 20 is provided with a matching connecting structure 202.

[0063] Based on the above design, the connection between the coil frame 12 and the yoke 20 is further improved by the connection part 104, ensuring that the coil module 10 and the yoke 20 are tightly connected together, and ensuring that the yoke 20 always covers and protects the electronic control coil 11. Furthermore, the connection part 104 has the advantages of simple structure, reliable connection, and low cost.

[0064] Optionally, such as Figures 1-3 As shown, the connecting part 104 is constructed as a hole structure, and the connecting structure 202 is constructed as a rod structure. The rod structure is inserted into the hole structure to achieve the connection.

[0065] As is easily understood, the yoke 20 can be connected to the coil frame 12 by simply plugging and unplugging it, which is convenient and easy to master. The connecting part 104 can be any suitable existing rod.

[0066] In one possible implementation, the end face of the coil frame 12 is provided with an outwardly extending radial limiting portion 107, which forms a snap-fit ​​groove for connecting the yoke 20. Based on the above design, the snap-fit ​​groove is formed by the radial limiting portion 107 to avoid radial gaps and prevent the edge of the yoke 20 from extending beyond the coil frame 12.

[0067] It is easy to understand that the radial limiting part 107 can be constructed in any suitable structure.

[0068] In one possible implementation, the guide rod 13 has a radial protrusion 108 extending into the coil holder 12, which is used to connect other components. Based on the above design, it mates with the inner circumferential surface of the coil holder 12 for better connection of other components. Optionally, as... Figure 3 As shown, the radial protrusion 108 can be any suitable existing rod.

[0069] In one possible implementation, the line cover 14 can be a split cover or a one-piece cover;

[0070] The split lid includes at least two lid bodies 105;

[0071] The integrated cover includes at least two cover bodies 105 and a central ring 106 for connecting the multiple cover bodies 105. Accordingly, when the integrated cover is applied to the groove, the central ring 106 is fitted onto the guide rod 13.

[0072] Based on the above design, the wire cover 14 not only protects the electronic control coil 11, but also connects the coil frame 12 and the yoke 20 to improve the connection effect between the coil module 10 and the yoke 20. The cover 105 can be constructed into any suitable shape to adapt to different usage environments.

[0073] Regarding the two implementation schemes for the line cover 14, namely the split cover and the integrated cover, the split cover offers greater flexibility in use, while the integrated cover is easier to assemble and disassemble. Staff can choose the appropriate scheme based on the actual situation to achieve the best results.

[0074] The electronically controlled adjustment device will be further described below in conjunction with the structure of the yoke 20:

[0075] In one possible implementation, the yoke 20 can be a separate piece or a single piece;

[0076] The split piece includes at least two sub-pieces, each of which is provided with a connecting structure 202. When the sub-pieces are covered on the wire groove, there is a gap between adjacent sub-pieces. Correspondingly, the guide rod 13 passes through the gap, and the wire cover 14 is located in the gap.

[0077] The integrated piece is provided with the through hole 201, the connection structure 202, and the mounting groove 203 adapted to the wire cover 14.

[0078] Based on the above design scheme, similar to the wire cover 14, the yoke 20 also has two implementation schemes: a split type and an integrated type. It is easy to understand that for the wire cover 14 and the yoke 20, workers can flexibly select and form various combination schemes to adapt to different usage environments. For the aforementioned electronic control adjustment device, the structural combination schemes are diverse, offering greater flexibility in use.

[0079] Optionally, the wire cover 14 can be a separate cover or a one-piece cover, and the yoke piece 20 can be a separate piece or a one-piece piece; correspondingly, when the wire cover 14 is a separate cover, the yoke piece 20 is a separate piece; when the wire cover 14 is a one-piece cover, the yoke piece 20 is a one-piece piece. Based on this, in general, the wire cover 14 and the yoke piece 20 are selected according to the above scheme, but if necessary, they can also be constructed in other combinations.

[0080] Optionally, such as Figure 1 and Figure 2 As shown, the first slot 101 has two sections arranged opposite each other on the coil frame 12, and the beam 102 includes two oppositely arranged sub-beams, each of which has a second slot 103. Based on this, the structure of the coil module 10 is simpler, which helps to reduce manufacturing costs.

[0081] This embodiment introduces an electrically controlled valve based on the aforementioned electrically controlled regulating device. The electrically controlled valve includes the aforementioned electrically controlled regulating device. Based on the above design, the electrically controlled valve can also include other suitable functional modules, resulting in richer functionality to meet different working requirements and improved practicality. Furthermore, it is readily understood that the functional modules can be selected from any suitable existing equipment, offering a wide range of choices.

[0082] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
