Description

Technical Field

[0001] This utility model relates to the field of electric valve technology, and more specifically, to an electric valve actuator. Background Technology

[0002] In modern industrial applications, the control systems of many devices require precision drive devices to perform various mechanical operations. These drive devices typically employ electric valve actuators to achieve precise control and ensure stable system operation.

[0003] However, in the existing technology, the housing design of electric valve actuators is relatively complex, and usually requires the use of special tools for disassembly, which makes the maintenance, inspection and repair of the equipment very inconvenient. This design inconvenience not only increases the time and cost of maintenance work, but may also lead to prolonged equipment downtime, affecting production efficiency and normal equipment operation.

[0004] The disassembly design of the housing and internal structure of traditional electric valve actuators does not fully consider ease of disassembly. As a result, when the equipment fails, operators need to spend a lot of time disassembling it in order to enter the interior for troubleshooting. This not only affects maintenance efficiency, but also reduces the availability of the equipment and the reliability of the production line. Utility Model Content

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an electric valve actuator, comprising a valve body and an actuator base shell, wherein the actuator base shell is connected to the top of the valve body and has an actuator housing at the top; quick-release mechanisms are provided on both sides of the actuator housing, each quick-release mechanism comprising an insertion rod, a snap-fit ​​rod, a fixing plate, a fixing sleeve, a slant groove, a slant block, a locking block, a slot, and a locking mechanism; the insertion rod is fixed to the top surface of the actuator base shell, the snap-fit ​​rod is fixed to the top of the insertion rod, the fixing plate is fixed to the outside of the actuator housing and is inserted into the insertion rod, the fixing sleeve is fixed to the top surface of the fixing plate, and multiple sets of slant grooves are provided on the inner wall of the fixing sleeve, with the slant block sliding in the multiple sets of slant grooves. Inside, the locking block is fixed to the inner side of multiple sets of inclined blocks, and multiple sets of locking grooves are distributed on the outer wall of the locking rod. The locking mechanism includes a sliding groove, a pressure ring, a transmission sleeve, a support plate, a limiting plate, a screw, a gear, a rotating sleeve, and a toothed ring. Multiple sets of sliding grooves are distributed on the outer wall of the fixed sleeve. The pressure ring is located inside the fixed sleeve. The transmission sleeve is fixed to the outside of the pressure ring and is slidably connected to multiple sets of sliding grooves. The support plate and the limiting plate are both fixed to the outer wall of the fixed sleeve. Multiple sets of screws are arranged, all rotating between the limiting plate and the support plate and all threadedly connected to the transmission sleeve. The gears are fixed to the top of multiple sets of screws. The rotating sleeve is rotatably installed on the outer wall of the fixed sleeve. The toothed ring is fixed to the outer wall of the rotating sleeve and meshes with multiple sets of gears.

[0009] The present invention is further configured such that a limiting block is provided on the outer wall of the snap-fit ​​rod, and a limiting hole is provided on the inner side of the fixing sleeve, with the limiting block inserted into the limiting hole. The cooperation between the limiting block and the limiting hole ensures accurate positioning of the snap-fit ​​rod, preventing its offset or detachment, thereby improving stability and safety during disassembly and installation.

[0010] The present invention is further configured such that both the limiting block and the limiting groove are polygonal. The polygonal limiting block and limiting groove enhance the stability of the connection, prevent loosening during high-frequency use, and ensure firmness and accuracy after long-term use.

[0011] This invention is further characterized in that each of the multiple sets of card slots has a clearance groove at its top. The clearance groove design makes it easier for the card block to disengage from the card slot, simplifies the disassembly process, avoids disassembly difficulties caused by overly tight card slots, and improves the ease of operation.

[0012] The present invention is further configured such that a compression spring is connected to the top surface of the inner sleeve, and a pressure plate is connected to the bottom end of the compression spring. The combined design of the compression spring and the pressure plate provides uniform pressure, ensuring the tightness of the outer shell and the internal structure, preventing the outer shell from loosening or vibrating, and improving the stability and safety of the equipment.

[0013] This invention is further configured such that a return spring is connected between the bottom surface of each of the multiple sets of inclined blocks and the fixing sleeve. The return spring design ensures that the inclined blocks can quickly return to their original position under external force, ensuring the stability of the locking blocks, avoiding jamming of the locking mechanism, and improving the smoothness of disassembly.

[0014] This invention is further configured such that a positioning mechanism is provided at the bottom end of the rotating sleeve. The positioning mechanism includes a positioning sleeve, push springs, a positioning block, and positioning grooves. The positioning sleeve is fixed to the bottom surface of the rotating sleeve. Multiple sets of push springs are fixed inside the positioning sleeve. The positioning block is fixedly connected to the bottom ends of multiple sets of push springs. Multiple sets of positioning grooves are distributed on the outer wall of the fixed sleeve. The positioning mechanism, through the cooperation of the push springs, positioning blocks, and positioning grooves, ensures the precise positioning of the rotating sleeve, avoids misalignment during disassembly and installation, and improves the accuracy and stability of the shell installation.

[0015] This invention is further configured such that the multiple sets of positioning grooves and the outer wall of the positioning block are all arc-shaped. The arc-shaped positioning grooves and the outer wall of the positioning block reduce friction during the positioning process, ensure the precise fit between the rotating sleeve and the fixed sleeve, and improve the operating efficiency and service life of the system.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides an electric valve actuator, which has the following advantages:

[0018] 1. The quick-release mechanism of this electric valve actuator significantly improves the efficiency of disassembly and installation of the device housing through a series of ingenious designs. The insertion rod is fixed to the top surface of the actuator's bottom housing, and the locking rod is inserted into the fixing plate. Through the cooperation of the locking block and the locking slot, the actuator housing can be quickly disassembled. The sliding of the inclined block in the inclined slot, through the action of the return spring, allows the locking block to smoothly disengage from the locking slot along the relief groove, thereby unlocking the locking rod and realizing the loosening and disassembly of the housing. This design does not require complicated tools. Users can simply rotate the rotating sleeve to complete the disassembly of the housing, which greatly improves the convenience and efficiency of maintenance.

[0019] 2. The locking mechanism ensures the stability and safety of the drive housing after installation. Through the cooperation of components such as the pressure ring, transmission sleeve, and screw, the locking mechanism ensures that the locking block is firmly locked into the slot. In particular, the locking rod is precisely positioned by the limit block and the limit hole, which avoids the misalignment of the components and ensures that the housing is always in a tight state during operation. The dual action of the compression spring and the return spring not only effectively maintains the system's fastening force, but also provides sufficient rebound force under external force, ensuring the reliability and durability of the locking mechanism in long-term use.

[0020] 3. The positioning mechanism design greatly enhances the precision of disassembly and installation of the housing. The rotating sleeve, through the synergistic action of the gear ring and gears, drives the screw to rotate and drives the locking block and locking rod to achieve precise positioning, ensuring that the housing maintains a stable connection state during disassembly and installation. The cooperation between the positioning block and the positioning groove allows the rotating sleeve to be positioned quickly and accurately when locked, effectively preventing deviations and misoperations during operation. This mechanism can not only withstand a certain amount of operating force, but also maintain the stability of the housing under the action of unbalanced forces, greatly improving the safety of the equipment and the user experience of the operator.

[0031] Please see Figures 1-6 An electric valve actuator includes a valve body 1 and an actuator base shell 2. The actuator base shell 2 is connected to the top of the valve body 1 and has an actuator housing 3 at its top. The actuator housing 3 has quick-release mechanisms on both sides. Each quick-release mechanism includes a rod 4, a locking rod 5, a fixing plate 6, a fixing sleeve 7, a slanted groove 8, a slanted block 9, a locking block 10, a locking groove 11, and a locking mechanism. The rod 4 is fixed to the top surface of the actuator base shell 2, the locking rod 5 is fixed to the top of the rod 4, the fixing plate 6 is fixed to the outside of the actuator housing 3 and engages with the rod 4, the fixing sleeve 7 is fixed to the top surface of the fixing plate 6, multiple sets of slanted grooves 8 are distributed on the inner wall of the fixing sleeve 7, the slanted blocks 9 slide within the multiple sets of slanted grooves 8, the locking blocks 10 are fixed to the inner side of the multiple sets of slanted blocks 9, and multiple sets of locking grooves 11 are distributed on the inner wall of the locking sleeve 7. The locking mechanism on the outer wall of the snap-fit ​​rod 5 includes a sliding groove 12, a pressure ring 13, a transmission sleeve 14, a support plate 15, a limiting plate 16, a screw 17, a gear 18, a rotating sleeve 19, and a toothed ring 20. Multiple sets of sliding grooves 12 are distributed on the outer wall of the fixed sleeve 7. The pressure ring 13 is located inside the fixed sleeve 7. The transmission sleeve 14 is fixed to the outside of the pressure ring 13 and is slidably connected to multiple sets of sliding grooves 12. The support plate 15 and the limiting plate 16 are both fixed to the outer wall of the fixed sleeve 7. Multiple sets of screws 17 are arranged and rotate between the limiting plate 16 and the support plate 15 and are threadedly connected to the transmission sleeve 14. The gear 18 is fixed to the top of multiple sets of screws 17. The rotating sleeve 19 is rotatably installed on the outer wall of the fixed sleeve 7. The toothed ring 20 is fixed to the outer wall of the rotating sleeve 19 and meshes with multiple sets of gears 18.

[0032] The outer wall of the snap-fit ​​rod 5 is provided with a limiting block 21, and the inner side of the fixing sleeve 7 is provided with a limiting hole 22, in which the limiting block 21 is inserted. Through the cooperation of the limiting block 21 and the limiting hole 22, the precise positioning of the snap-fit ​​rod 5 is ensured, preventing the snap-fit ​​rod from shifting or falling off, thereby improving the stability and safety of disassembly and installation.

[0033] Both the limiting block 21 and the limiting groove are polygonal. The polygonal shape of the limiting block 21 and the limiting groove enhances the stability of the connection, prevents loosening or falling off during long-term use, and ensures a firm connection that is not easily misaligned.

[0034] Each of the multiple card slots 11 has a clearance groove 23 at its top. The clearance groove 23 makes it easier for the card block to disengage from the card slot, reduces friction during disassembly, avoids the card slot being too tight and causing disassembly difficulties, and simplifies the operation process.

[0035] A compression spring 24 is connected to the top surface of the inner sleeve 7, and a pressure plate 25 is connected to the bottom end of the compression spring 24. The combination of the compression spring 24 and the pressure plate 25 provides uniform pressure, ensuring the fastening of the fixed sleeve 7 and the internal structure, preventing the outer shell from loosening or vibrating, and improving the stability of the equipment.

[0036] Each of the multiple sets of inclined blocks 9 has a return spring 26 connected between its bottom surface and the fixed sleeve 7. The design of the return spring 26 ensures that the inclined blocks 9 can quickly return to their original position under external force, thereby maintaining stable engagement, preventing jamming or malfunction of the engagement mechanism, and ensuring smooth operation.

[0037] A positioning mechanism is provided at the bottom of the rotating sleeve 19. The positioning mechanism includes a positioning sleeve 27, a push spring 28, a positioning block 29, and a positioning groove 30. The positioning sleeve 27 is fixed to the bottom surface of the rotating sleeve 19. Multiple sets of push springs 28 are fixed inside the positioning sleeve 27. The positioning block 29 is fixedly connected to the bottom ends of multiple sets of push springs 28. Multiple sets of positioning grooves 30 are distributed on the outer wall of the fixed sleeve 7. Through the coordinated action of the push springs 28, the positioning block 29, and the positioning grooves 30, the positioning mechanism ensures that the rotating sleeve 19 can be accurately positioned, avoiding misalignment, thereby improving the accuracy of the outer shell and internal structure.

[0038] The outer walls of the multiple positioning grooves 30 and positioning blocks 29 are all designed to be arc-shaped. The arc-shaped positioning grooves 30 and positioning blocks 29 reduce friction, ensure smooth fit between the rotating sleeve and the fixed sleeve, and improve the stability and long service life of the system.

[0039] In this embodiment, when the internal structure of the driver needs to be repaired and inspected, rotating the rotating sleeve 19 drives the gear ring 20 to rotate, the gear ring 20 drives multiple sets of gears 18 to rotate, and the multiple sets of gears 18 respectively drive multiple sets of screws 17 to rotate and engage with the transmission sleeve 14 by threads, so that the transmission sleeve 14 slides along the slide groove 12 and releases the pressure ring 13 from the contact of multiple sets of locking blocks 10. Multiple sets of reset springs 26 push the inclined block 9 to slide along the inclined groove 8, driving the multiple sets of locking blocks 10 to move along the relief groove 23 and disengage from the locking groove 11, thereby releasing the locking of the locking rod 5. Then, the compression spring 24 resets and pushes the pressure plate 25, so that the pressure plate 25 pushes the locking rod 5 to pop out of the fixing sleeve 7, completing the disassembly of the driver housing 3.

[0040] More specifically, when the driver housing 3 needs to be installed, the fixing plate 6 is inserted into the insertion rod 4, and then the locking rod 5 is inserted into the fixing sleeve 7. It is positioned and inserted through the limiting block 21 and the limiting hole 22. The top of the locking rod 5 pushes the pressure plate 25 to squeeze the compression spring 24. Then, the rotating sleeve 19 meshes with multiple sets of gears 18 through the gear ring 20, driving multiple sets of screws 17 to rotate. The multiple sets of screws 17 drive the transmission sleeve 14 to slide along the slide groove 12, thereby driving the pressure ring 13 to push multiple sets of locking blocks 10 so that they slide along the inclined groove 8 through the inclined block 9 and lock into the locking groove 1. Within 1, multiple sets of return springs 26 are simultaneously compressed. When the rotating sleeve 19 rotates, it drives the positioning sleeve 27 to rotate. Multiple sets of positioning blocks 29 cooperate with the arc-shaped design of the positioning groove 30 through their outer walls, so that the multiple sets of positioning blocks 29 contract to compress the push spring 28. When the multiple sets of positioning blocks 29 move into the next set of positioning grooves 30, the push spring 28 pushes the positioning block 29 to engage in the positioning groove 30. The user needs to apply a certain force to rotate the rotating sleeve 19. After the engagement is completed, the rotating sleeve 19 is positioned by the positioning block 29 engaging in the positioning groove 30.

[0041] In summary, during the use or operation of the overall equipment: when maintenance and inspection of the internal structure of the driver are required, rotating the rotating sleeve 19 drives the gear ring 20 to rotate, the gear ring 20 drives multiple sets of gears 18 to rotate, and the multiple sets of gears 18 respectively drive multiple sets of screws 17 to rotate and engage with the transmission sleeve 14 by threads, so that the transmission sleeve 14 slides along the slide groove 12 and releases the pressure ring 13 from the contact of multiple sets of locking blocks 10. Through multiple sets of return springs 26, the inclined block 9 is pushed to slide along the inclined groove 8, which drives the multiple sets of locking blocks 10 to move along the relief groove 23 and disengage from the locking groove 11, thereby releasing the locking of the locking rod 5. Then, through the compression spring 24, the pressure plate 25 is pushed to push the locking rod 5 out of the fixing sleeve 7, thus completing the disassembly of the driver housing 3.

[0042] When the drive housing 3 needs to be installed, the fixing plate 6 is inserted into the insertion rod 4, and then the locking rod 5 is inserted into the fixing sleeve 7. It is positioned and inserted through the limiting block 21 and the limiting hole 22. The top of the locking rod 5 pushes the pressure plate 25 to squeeze the compression spring 24. Then, the rotating sleeve 19 meshes with multiple sets of gears 18 through the gear ring 20 to drive multiple sets of screws 17 to rotate. The multiple sets of screws 17 drive the transmission sleeve 14 to slide along the slide groove 12, thereby driving the pressure ring 13 to push multiple sets of locking blocks 10 so that they slide along the inclined groove 8 through the inclined block 9 and lock into the locking groove 11. Simultaneously, multiple sets of reset springs 26 are compressed. When the rotating sleeve 19 rotates, it drives the positioning sleeve 27 to rotate. Multiple sets of positioning blocks 29 cooperate with the arc-shaped design of the positioning groove 30 through their outer walls, so that the multiple sets of positioning blocks 29 contract to compress the push spring 28. When the multiple sets of positioning blocks 29 move into the next set of positioning grooves 30, the push spring 28 pushes the positioning block 29 to engage in the positioning groove 30. The user needs to apply a certain force to rotate the rotating sleeve 19. After the engagement is completed, the rotating sleeve 19 is positioned by the positioning block 29 engaging in the positioning groove 30.

For all the fixed connections mentioned above, welding is preferred.
