[0058] As Figures 1 to 9As shown, the embodiment of the present application provides an electromagnetic drive plug-in valve, which comprises a valve body 1, a valve plate 2, a magnetic drive first module 3 and a magnetic drive second module 4. Wherein, the valve body 1 at least comprises a first part 11 and a second part 12, the first part 11 and the second part 12 are buckled and sealed with each other. The first part 11 and the second part 12 are respectively provided with a first fluid port 13 and a second fluid port 14, and the inside of the buckled valve body 1 has a containing space 15.

The magnetic drive second module 4 is provided with a power-on interface 5, and after the magnetic drive second module 4 is powered on, the generated magnetic field can cause driving force to the magnetic drive first module 3, so that the valve plate 2 can reciprocate to open or close the passage of the first fluid port 13 and the second fluid port 14.

[0059] Specifically, in the embodiment, the valve body 1 at least comprises a first part 11 and a second part 12, the first part 11 and the second part 12 are buckled and sealed with each other to constitute the valve body 1. The inside of the buckled valve body 1 has a containing space 15. In an example, the overall shape of the outside of the valve body 1 is a square body, for example, the overall shape of the outside of the valve body 1 can be a cuboid or a square. In another example, in the moving direction of the valve plate 2, the width between the opposite first end and second end of the valve body 1 gradually narrows, and specifically, the width of the first end to the second end provided with the first fluid port 13 and the second fluid port 14 gradually narrows.

[0060] In the embodiment, the first part 11 is provided with the first fluid port 13, and the second part 12 is provided with the second fluid port 14. The shape of the first fluid port 13 and the second fluid port 14 can be set according to the interface shape of the docking device, such as circular, square, etc. After the first part 11 and the second part 12 are buckled with each other, the first fluid port 13 and the second fluid port 14 are arranged opposite and coincident, and the caliber of the first fluid port 13 and the second fluid port 14 is the same. In an example, the first fluid port 13 comprises a first inner docking ring 131 and a first outer flange 132, wherein the first inner docking ring 131 protrudes from the inner side end face of the first part 11, and the first outer flange 132 protrudes from the outer side end face of the first part 11. Correspondingly, the second fluid port 14 comprises a second inner docking ring 141 and a second outer flange 142, wherein the second inner docking ring 141 protrudes from the inner side end face of the second part 12, and the second outer flange 142 protrudes from the outer side end face of the second part 12. After the first part 11 and the second part 12 are buckled, the first inner docking ring 131 and the second inner docking ring 141 are opposite, and the opposite distance is the thickness of the valve plate 2, specifically, the opposite distance is slightly higher than the thickness of the valve plate 2.

[0061] In the embodiment, to improve the sealing degree of the first inner abutting ring 131 and the second inner abutting ring 141 relative to the sealing valve plate 2, a sealing groove 17 and a sealing ring (specifically, an O-shaped sealing ring, not shown) are further included. The sealing groove 17 is arranged around the first inner abutting ring 131 and / or the second inner abutting ring 141, and the sealing ring is installed in the sealing groove 17. Specifically, in an example, the sealing groove 17 is arranged around the first inner abutting ring 131 or the second inner abutting ring 141, and the sealing ring is installed in the sealing groove 17. In an example, the sealing groove 17 includes a first sealing groove and a second sealing groove, the first sealing groove is arranged on the first inner abutting ring 131, the second sealing groove is arranged on the second inner abutting ring 141, the first sealing groove and the second sealing groove are opposite when the first inner abutting ring 131 and the second inner abutting ring 141 are opposite, the sealing ring is installed in the first sealing groove and the second sealing groove respectively, and the sealing ring is attached to the front and back end faces of the valve plate 2 respectively when the first inner abutting ring 131 and the second inner abutting ring 141 are opposite to the sealing valve plate 2.

[0062] In the embodiment, the outer side end face of the first part 11 and the outer side end face of the second part 12 are further respectively provided with a reinforcing rib 9. The advantage of arranging the reinforcing rib 9 is that not only the strength of the first part 11 and the second part 12 can be improved, but also the weight of the first part 11 and the second part 12 can be reduced.

[0063] In the embodiment, the inner side of the first part 11 is arranged as a groove structure, and the groove bottom of the groove structure is the inner side end face of the first part 11. The first inner abutting ring 131 is protrudingly arranged on the groove bottom of the groove structure. The inner side of the second part 12 is arranged as a flat plate structure, and the plane of the flat plate structure is the inner side end face of the second part 12. The second inner abutting ring 141 is protrudingly arranged on the plane of the flat plate structure. The edge plane of the flat plate structure is attached to the groove edge of the groove structure. Arranging the inner side of the first part 11 as a groove structure and arranging the inner side of the second part 12 as a flat plate structure can improve the stability of accommodating the valve plate 2. In an example, corresponding to the foregoing, the width between the first end and the second end of the groove body of the groove structure gradually narrows.

[0064] Of course, in other examples, the inner side of the first part 11 is arranged as a first half-groove structure, the inner side of the first part 11 is arranged as a second half-groove structure, and the first half-groove structure and the second half-groove structure are buckled to form the accommodating space 15 inside the valve body 1.

Alternatively, the buckling groove is arranged around the edge of the flat plate structure, and the buckling protrusion is arranged around and protrudes from the edge of the groove structure. The buckling protrusion is buckled in the buckling groove to achieve buckling of the first part 11 and the second part 12.

[0066] In an example, the opposite edges of the groove structure and the flat plate structure are further provided with a positioning structure, which can be arranged preferentially at the corner positions of the opposite edges of the groove structure and the flat plate structure. The positioning structure comprises a positioning pin and a positioning hole. The positioning pin is arranged at the corner of the groove structure, and the positioning hole is recessed at the corner of the flat plate structure. The positioning pin is inserted into the positioning hole to achieve positioning of the first part 11 and the second part 12. Alternatively, the positioning hole is recessed at the corner of the groove structure, and the positioning pin is arranged at the corner of the flat plate structure. The positioning pin is inserted into the positioning hole to achieve positioning of the first part 11 and the second part 12.

[0067] In an example, the opposite edges of the groove structure and the flat plate structure are further provided with a sealing structure, which comprises a first half-sealing groove, a second half-sealing groove, and a sealing rubber ring 16. The first half-sealing groove is arranged around the edge of the groove structure, and the second half-sealing groove is arranged around the edge of the flat plate structure. After the first part 11 and the second part 12 are buckled, the first half-sealing groove and the second half-sealing groove are arranged oppositely, and the sealing rubber ring 16 is inserted into the first half-sealing groove and the second half-sealing groove to achieve sealing of the first part 11 and the second part 12 when buckled.

[0068] In the present embodiment, to further improve the sealing degree of the first part 11 and the second part 12 when buckled, the joint of the first part 11 and the second part 12 after buckling is welded by welding.

[0069] In an example, the first part 11 and the second part 12 can be screwed when buckled.

[0070] After the first part 11 and the second part 12 are buckled and sealed, an accommodation space 15 can be formed in the interior of the valve body 1. In an example, the accommodation space 15 is mainly the cavity space of the groove structure. The valve plate 2 is arranged in the accommodation space 15 of the valve body 1 and can reciprocate along at least one moving direction. In the present embodiment, the form of the valve plate 2 is arranged according to the structural form of the cavity space of the groove structure, so as to accommodate the valve plate 2 in the cavity space of the groove structure. For example, in the moving direction, the width between the opposite first end and second end of the valve plate 2 gradually narrows, wherein the first end of the valve plate 2 is close to the first end of the valve body 1.

[0071] In the embodiment, the valve plate 2 is further provided with a buffer structure 21 arranged on the front and back end faces of the valve plate 2, and the buffer structure 21 can abut against the inner side of the front end face of the valve body 1. The front end face of the valve plate 2 is parallel to the front end face of the valve body 1, and the front end face of the valve body 1 is the end face on which the first fluid port 13 and the second fluid port 14 are distributed. In an example, the buffer structure 21 includes limiting clamping grooves and a spring, wherein the limiting clamping grooves are arranged at four corners of the front and back end faces respectively, and the spring is arranged in a U-shaped structure, the two ends of the spring are inserted into the limiting clamping grooves, and the protruding part of the spring can abut against the inner side of the front end face of the valve body 1. In an example, the buffer structure 21 includes a piston ring support.

[0072] In the embodiment, the movement of the valve plate 2 relative to the valve body 1 is achieved by the magnetic drive first module 3 and the magnetic drive second module 4. Specifically, the magnetic drive first module 3 is arranged on one side of the valve plate 2 in the moving direction, and the magnetic drive second module 4 is arranged on the corresponding side of the valve body 1 and the valve plate 2. The magnetic drive second module 4 is provided with an energization interface 5, and after the magnetic drive second module 4 is energized, the magnetic field generated can cause a driving force on the magnetic drive first module 3, so that the valve plate 2 can reciprocate to open or close the passageway of the first fluid port 13 and the second fluid port 14.

[0073] In an example, the magnetic drive second module 4 can be arranged on one side of the first part 11 or one side of the second part 12.

[0074] In the embodiment, the magnetic drive first module 3 is arranged on one side of the valve plate 2 in the moving direction, and the magnetic drive second module 4 is arranged on the corresponding side of the valve body 1 and the valve plate 2 in two arrangement modes as follows:

[0075] Specifically, mode one: the magnetic drive first module 3 is arranged on one side of the valve plate 2 in the moving direction, including: the magnetic drive first module 3 is arranged on two opposite sides of the valve plate 2 in the moving direction. For example, the overall shape of the valve plate 2 is a square body, which has oppositely arranged long side and wide side, and in this example, the magnetic drive first module 3 is arranged on two opposite long sides of the valve plate 2 in the moving direction. Correspondingly, the magnetic drive second module 4 is arranged on the corresponding sides of the valve body 1 and the valve plate 2, including: the magnetic drive second module 4 is arranged on two opposite sides of the valve body 1 and the valve plate 2. That is, the overall shape of the valve body 1 is a square body, which has oppositely arranged long side and wide side, and in this example, the magnetic drive second module 4 is arranged on two opposite long sides of the valve body 1 in the moving direction. The magnetic drive first module 3 is arranged on two opposite sides of the valve plate 2, and the magnetic drive second module 4 is arranged on two opposite sides of the valve body 1, so that the valve plate 2 is subjected to the driving force of the magnetic drive first module 3 caused by the magnetic field generated after the magnetic drive second module 4 is energized, so as to improve the stability of operation.

[0076] The second mode is to arrange the magnetic drive first module 3 on one side of the valve plate 2 in the moving direction, including arranging the magnetic drive first module 3 on one side of the valve plate 2 in the moving direction. For example, the overall shape of the valve plate 2 is a square body, which has a long side and a wide side arranged oppositely, and in this example, the magnetic drive first module 3 is arranged on one side of the long side of the valve plate 2 in the moving direction. Correspondingly, the second module is arranged on the corresponding side of the valve body 1 and the valve plate 2, including arranging the second module on one side of the valve body 1 and the valve plate 2. That is, the overall shape of the valve body 1 is a square body, which has a long side and a wide side arranged oppositely, and in this example, the magnetic drive second module 4 is arranged on one side of the long side of the valve body 1 in the moving direction.

[0077] Correspondingly, it also includes a guide sliding structure (not shown), which is arranged on the other side of the valve plate 2 in the moving direction and on the other side of the valve body 1 and the valve plate 2. Specifically, in an example, the guide sliding structure includes a guide rail and a guide wheel, wherein the guide rail is arranged on the other side of the valve plate 2 in the moving direction, and the guide wheel is arranged on the other side of the valve body 1 and the valve plate 2. This arrangement not only improves the stability of the lifting operation, but also reduces the number of magnetic drive first module 3 and magnetic drive second module 4, thereby reducing production costs.

[0078] Further, in this embodiment, the magnetic drive second module 4 includes a receiving groove 41, an iron core 42, a plurality of energized coils 43, a connecting wire (not labeled), and a packaging plate 44. The receiving groove 41 is arranged on one side of the valve plate 2 in the moving direction. In an example, to facilitate the assembly of the iron core 42, the energized coils 43, and the connecting wire, the receiving groove 41 can be arranged on the outside of the valve plate 2, such as the long outer side of the valve plate 2. The plurality of energized coils 43 are installed side by side in the receiving groove 41 in the moving direction. The cylindrical structure of the iron core 42 is inserted into the middle of each energized coil 43. The connecting wire connects each energized coil 43 in series, and the connecting wire is connected to the energized interface 5. After the iron core 42, the plurality of energized coils 43, and the connecting wire are installed in the receiving groove 41, the iron core 42, the plurality of energized coils 43, and the connecting wire are installed and packaged by the packaging plate 44.

[0079] Of course, in other examples, other structures can be used to install the iron core 42, the plurality of energized coils 43, and the connecting wire, such as a press-fit plate, which limits the iron core 42, the plurality of energized coils 43, and the connecting wire in the receiving groove 41.

[0080] In an example, the magnetic drive second module 4 can be divided into a plurality of magnetic drive second sub-modules 45, and the plurality of magnetic drive second sub-modules 45 are arranged at equal intervals on the corresponding side of the valve body 1 and the valve plate 2. Each magnetic drive second sub-module 45 has the same structure as the magnetic drive second module 4. The interval between each adjacent two magnetic drive second sub-modules 45 is an integer multiple of the width of the S-pole magnet 32 or the N-pole magnet 33 (described below).

[0081] Correspondingly, in the present embodiment, the magnetic drive first module 3 includes a plurality of accommodating grooves 31, a plurality of S-pole magnets 32, N-pole magnets 33, and a press-fit strip 34.

After the plurality of S-pole magnets 32 and the N-pole magnets 33 are arranged alternately in the corresponding accommodating grooves 31 along the moving direction, the press-fit strip 34 encapsulates the S-pole magnets 32 and the N-pole magnets 33 in the accommodating grooves 31. It should be noted that the S-pole magnets 32 and the N-pole magnets 33 described in the present embodiment are defined by the polarity of the end face of the magnet, that is, a magnet has two parts of S-pole and N-pole. When the end face of the S-pole magnet 32 faces the magnetic drive second module 4, the magnet is defined as the S-pole magnet 32. Correspondingly, when the end face of the N-pole magnet 33 faces the magnetic drive second module 4, the magnet is defined as the N-pole magnet 33.

[0082] Based on the present embodiment, the magnetic drive second module 4 is divided into a plurality of magnetic drive second sub-modules 45, and the alternately arranged S-pole magnets 32 and N-pole magnets 33 are correspondingly arranged into a plurality of magnetic drive first sub-modules according to a predetermined number. Compared with the driving mode of the prior art driving structure using a rotating motor + transmission mechanism, the magnetic force driving structure of the magnetic drive first module 3 and the magnetic drive second module 4 is simpler, thereby facilitating assembly. In addition, the driving mode of the magnetic drive first module 3 and the magnetic drive second module 4 also has higher stability and faster driving speed, which can improve the use efficiency of the plug-in valve. Furthermore, the length of the plug-in valve is not limited by the mechanical structure, thereby meeting the needs of different scenes for the plug-in valve.

[0083] In the present embodiment, in order to clearly determine the moving position of the valve plate 2 in the valve body 1, a position sensing device 7 is further provided. The position sensing device 7 is arranged at the end of one side of the valve body 1, and is used to sense the sliding position of the valve plate 2.

[0084] In the present embodiment, a control interface 6 is further included. The control interface 6 is arranged outside one side of the valve body 1, and can be connected with an external device. The other end of the control interface 6 is connected with the magnetic drive second module 4, so as to control the operation of the plug-in valve on the external device by controlling the magnetic drive second module 4.

[0085] In the embodiment, an encoder 8 is further included, which is arranged outside one side of the valve body 1 and connected with the magnetic drive second module 4. The encoder 8 is used to control the direction of the magnetic field generated after the magnetic drive second module 4 is powered on, and the generated magnetic field can cause the driving force of the magnetic drive first module 3 to drive the linear displacement of the valve plate 2.

[0086] The embodiment of the application provides an electromagnetic drive plug-in valve, which comprises a valve body 1, a valve plate 2, a magnetic drive first module 3 and a magnetic drive second module 4. The valve body 1 comprises at least a first part 11 and a second part 12, and the first part 11 and the second part 12 are mutually buckled and sealed. The first part 11 and the second part 12 are respectively provided with a first fluid port 13 and a second fluid port 14, and the inside of the buckled valve body 1 has a containing space 15. The valve plate 2 is arranged in the containing space 15 of the valve body 1 and can reciprocate along at least one moving direction. The magnetic drive first module 3 is arranged on one side of the valve plate 2 in the moving direction, and the magnetic drive second module 4 is arranged on the corresponding side of the valve body 1 and the valve plate 2. The magnetic drive second module 4 is provided with a power-on interface 5, and after the magnetic drive second module 4 is powered on, the generated magnetic field can cause the driving force of the magnetic drive first module 3, so that the valve plate 2 can reciprocate to open or close the passageway of the first fluid port 13 and the second fluid port 14.

[0087] The embodiment of the application sets the valve body 1 as at least the first part 11 and the second part 12, and the first part 11 and the second part 12 are mutually buckled and sealed, so as to improve the air tightness of the valve body 1. Secondly, the magnetic drive first module 3 is arranged on one side of the valve plate 2 in the moving direction, the magnetic drive second module 4 is arranged on the corresponding side of the valve body 1 and the valve plate 2, the valve plate 2 is integrally arranged with the magnetic drive first module 3, and the second module is integrally arranged with the valve body 1, instead of using the driving mode of the rotary motor driving the transmission mechanism, so that the structure of the plug-in valve is more simplified. In addition, the magnetic field generated by the magnetic drive first module 3 and the magnetic drive second module 4 can cause the driving force of the magnetic drive first module 3, so that the valve plate 2 can reciprocate to open or close the passageway of the first fluid port 13 and the second fluid port 14, and the mechanical structure is reduced, so as to avoid the phenomenon of being stuck in the long running process and improve the response effect of valve opening or closing.

Any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of the application, and all the changes and modifications are within the protection scope of the application.
