Description

Technical Field

[0001] This utility model relates to the field of industrial flow control, and in particular to an electrical conversion module that uses permanent magnets to reduce power consumption. Background Technology

[0002] Valve positioners, classified by structure into pneumatic valve positioners, electro-pneumatic valve positioners, and intelligent valve positioners, are the main accessories of control valves. They are usually used in conjunction with pneumatic control valves. They receive the output signal from the controller and then use their output signal to control the pneumatic control valve. After the control valve is activated, the displacement of the valve stem is fed back to the valve positioner through a mechanical device, and the valve position status is transmitted to the upper system through an electrical signal.

[0003] The key component of a valve positioner is the electrical conversion module, whose main function is to convert electrical signals into pneumatic signals. By amplifying the back pressure of the nozzle and controlling the flow, it provides sufficient power to operate the pneumatic control valve. The accuracy, real-time performance, reliability, vibration resistance, and low power consumption of the electrical conversion module directly affect the overall performance of the valve positioner. Designing a superior electrical conversion module is crucial for achieving intelligent valve positioners.

[0004] Electrical conversion modules typically regulate gas pressure and flow by adjusting the distance between a baffle and a nozzle. The baffle is fixed to a spring, and the electromagnetic force of an electromagnetic coil drives the spring to deform, thus achieving the regulation function. However, relying solely on the current in the electromagnetic coil to generate sufficient electromagnetic force results in relatively high power consumption. If auxiliary electromagnetic force could be provided by incorporating permanent magnets or similar methods, it would be possible to reduce the power consumption of the electrical conversion module. Summary of the Invention

[0005] To address the aforementioned problems in existing technologies, this utility model provides an electrical conversion module that utilizes permanent magnets to reduce power consumption. By setting a magnet to reduce the electromagnetic force required by the electromagnetic coil, and designing the outer shell as a magnetically conductive structure to reduce the diffusion of magnetic lines of force, the module achieves excellent technical effects such as lower operating current, higher sensitivity, and greater resistance to gas pressure.

[0006] The technical solution of this utility model is as follows:

[0007] An electrical conversion module that uses permanent magnets to reduce power consumption includes a screw 1, a lower shell 2, a nozzle 3, a baffle 4, a spring 5, a coil 6, a coil shell 7, a circuit board assembly 8, a magnet 9, and an adjusting rod 10.

[0008] The lower shell 2 has screw mounting holes on its edge for connecting the coil shell 7; a through hole is opened in the center of the lower shell 2 for fixing the nozzle 3.

[0009] The nozzle 3 is a hollow cylindrical structure. The bottom of the lower shell 2 is connected to the nozzle 3. The lower shell 2 and the coil shell 7 form a gap, and the nozzle 3 is connected to the gap.

[0019] Furthermore, the spring 5 is cut from a thin plate and is divided into three parts: a support ring 501, an elastic beam 502, and a baffle fixing ring 503.

[0020] The baffle fixing ring 503 is a circular ring structure used to fix the baffle 4; when the baffle 4 moves up and down under the action of external force, the baffle fixing ring 503 moves together with the baffle 4.

[0021] The elastic beam 502 is a slender strip structure. When the baffle 4 is subjected to external force, the elastic beam 502 deforms, allowing the baffle 4 to move up and down.

[0022] The support ring 501 is a circular ring structure used to fix the elastic beam 502.

[0023] Furthermore, the cross-section of the elastic beam 502 is shaped like the character "ㄣ".

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] The electrical conversion module of the embodiment is as follows: Figure 1 As shown, it consists of screw 1, lower shell 2, nozzle 3, baffle 4, spring 5, coil 6, coil shell 7, circuit board assembly 8, magnet 9 and adjusting rod 10.

[0035] The lower shell 2 is a circular thin plate structure with three screw mounting holes on its edge for connecting the coil shell 7. The lower shell 2 has a through hole in its center for fixing the nozzle 3.

[0036] Nozzle 3 is a hollow cylindrical structure. Gas flows into nozzle 3 from the bottom of lower shell 2 and then flows out from the gap between lower shell 2 and coil shell 7.

[0037] The baffle 4 is a thin circular plate fixed to the spring 5 and connected to the lower shell 2 via the spring 5. The baffle 4 is located above the nozzle 3, and its central axis coincides with the central axis of the nozzle 3.

[0038] like Figure 2 As shown, spring 5 is a circular thin-plate structure, cut from a thin plate, and is essentially composed of three parts: a support ring 501, an elastic beam 502, and a baffle fixing ring 503. The baffle fixing ring 503 is a circular ring structure used to fix the baffle 4; when the baffle 4 moves up and down under external force, the baffle fixing ring 503 moves along with the baffle 4. The elastic beam 502 is a slender strip structure with a "ㄣ"-shaped cross-section; when the baffle 4 is subjected to external force, the elastic beam 502 deforms, allowing the baffle 4 to move up and down. The support ring 501 is a circular ring structure used to fix the elastic beam 502. The edge of the support ring 501 has three mounting holes for connecting to the lower shell 2.

[0039] By designing the spring in this way, it can be manufactured using CNC technology, requiring only a cutting process, resulting in very low processing costs.

[0040] The coil 6 is fixed above the spring 5, maintaining a certain distance from the spring 5, and the central axis of the coil 6 coincides with the central axis of the baffle 4.

[0041] The coil housing 7 is a cylindrical structure with an open bottom and a closed thin plate at the top, referred to as the top plate. Three screw mounting holes are provided on the edge of the coil housing 7 for connecting to the lower housing 2. By sequentially passing screws 1 through the screw mounting holes of the lower housing 2, the spring 5, and the coil housing 7, the lower housing 2, spring 5, and coil housing 7 can be connected into a single unit, with the coil 6 sealed inside this unit. The circuit board assembly 8 is fixed to the top plate of the coil housing 7 and is used to adjust the current of the coil 6.

[0042] A threaded hole is provided in the center of the top plate for mounting the adjusting rod 10. The adjusting rod 10 is a cylindrical structure with threads and is fixed inside the coil 6 through the threaded hole in the top plate. The magnet 9 is fixed to the bottom of the adjusting rod 10, and the distance between the magnet 9 and the baffle 4 can be adjusted by rotating the adjusting rod 10.

[0043] Under the combined influence of the magnetic force of magnet 9, the elastic force of spring 5, the gas pressure, and the electromagnetic force of coil 6, baffle 4 moves up and down above nozzle 3. When the current in coil 6 increases, baffle 4 moves away from nozzle 3, resulting in decreased gas pressure and increased flow rate. When the current in coil 6 decreases, baffle 4 moves closer to nozzle 3, resulting in increased gas pressure and decreased flow rate. By adjusting the magnitude of the current, the gas pressure and flow rate can be adjusted.

[0044] The lower shell 2, baffle 4, spring 5, and coil shell 7 are all made of soft magnetic materials. When the coil 6 is energized, all four are magnetized, which enhances the force exerted by the coil 6 on the baffle 4 and also reduces the diffusion of magnetic lines of force and interference with external equipment.

[0045] The appearance after assembly of the embodiment is as follows Figure 3 As shown.

They can be applied to various fields suitable for this utility model. For those skilled in the art, and for those of ordinary skill in the art, various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details.
