Description

Technical Field

[0001] This utility model relates to the field of switching valve technology, and specifically to a multifunctional switching valve actuator. Background Technology

[0002] In critical fields such as industrial fluid control, municipal pipeline network operation and maintenance, and energy transmission systems, valve actuators are core equipment for achieving precise opening and closing control of pipeline valves, and are crucial for ensuring stable system operation and orderly fluid transport. These actuators are mainly divided into two categories: one is an electrically driven mechanism powered by a drive source, enabling automated and routine valve control; the other is a manually operated mechanism, serving as an emergency backup device. In the event of a malfunction in the electrically driven mechanism, power outage, or other emergencies, manual intervention can promptly open and close the valve, effectively preventing system shutdowns or media leaks caused by valve malfunction.

[0003] However, the manual control components of existing on / off valve actuators generally have design limitations. Their manual mechanisms often employ a single-speed transmission structure, lacking a flexible speed adjustment mechanism. This means the valve's opening and closing speed is entirely determined by the operator's manual operation rate, making adaptive adjustments impossible based on actual operating conditions. In scenarios requiring rapid response, such as emergencies, the single-speed design struggles to achieve rapid valve opening and closing, potentially delaying fault handling and leading to severe damage to the pipeline system, thus impacting overall operational safety and reliability. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a multifunctional switching valve actuator, which solves the problem that the manual control part of the existing switching valve actuator has only one operating position and cannot meet the application requirements of different opening and closing speed scenarios.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a multifunctional switching valve actuator, comprising: a housing, wherein an output shaft is connected to the housing via a transmission assembly, and a first gear engagement assembly and a second gear engagement assembly are also provided within the housing; wherein, the first gear engagement assembly includes a first gear ring and a first gear meshing with each other, and the second gear engagement assembly includes a second gear ring and a second gear meshing with each other, wherein both the first gear and the second gear are connected to the transmission assembly, and both the first gear ring and the second gear ring are driven by the engagement assembly.

[0006] Optionally, the housing may also include a drive source, which is connected to the transmission assembly via a switching mechanism.

[0007] Optionally, the transmission assembly includes a worm and a worm wheel that mesh with each other. The worm is connected to the housing through a bearing seat, and the worm wheel is connected to the housing through a wheel seat. The worm wheel is fixed on the output shaft, and a connecting rod is fixed to one side of the worm. The first gear and the second gear are both fixed on the connecting rod.

[0008] Optionally, the housing is provided with a toggle groove, and the switching mechanism includes a first convex shaft and a second convex shaft. The first convex shaft and the second convex shaft are both disposed in the housing through a bearing seat. The first convex shaft and the second convex shaft are connected to each other through a snap-fit ​​part. A toggle part is rotatably connected to the snap-fit ​​part, and the toggle part is slidably connected in the toggle groove.

[0009] Optionally, both the first toothed ring and the second toothed ring are provided with a plurality of meshing grooves, and a meshing rod that matches the meshing groove is rotatably connected to the outer circumference of the meshing part. The meshing rod and the meshing part are also connected by a damper.

[0010] Optionally, the first meshing assembly further includes a first screwing part, on which a screwing rod is fixed, and the screwing rod is fixed to one of the meshing parts.

[0011] Optionally, the second meshing assembly further includes a second screwing part, on which a sleeve is fixed. The sleeve is fixed on one of the meshing parts, and is sleeved outside the screwing rod. The sleeve is rotatably connected to the outer shell.

[0012] Optionally, both the first toothed ring and the second toothed ring are connected to the housing via wheel seats.

[0013] Optionally, a control module is also provided inside the housing.

[0014] Optionally, the meshing grooves on the first toothed ring and the meshing grooves on the second toothed ring are distributed in opposite directions.

[0015] The beneficial effects of this utility model are as follows: This invention uses a gear ring meshing system to drive the rotation of a transmission unit, which in turn transmits the rotational speed to the transmission unit. Two independent gear meshing transmission structures can each provide different speed outputs. In manual control scenarios, operators can independently select the appropriate speed mode and flexibly adjust the valve opening and closing rate according to actual working conditions. This satisfies both the rapid response requirements in emergency scenarios and the stable operation requirements in fine-tuning scenarios, ultimately achieving comprehensive adaptability to various application scenarios.

[0016] Meanwhile, the toothed ring of this invention is internally equipped with a meshing part, and the meshing part is rotatably connected to a meshing rod on its outer circumference. The inner sides of the first and second toothed rings are provided with meshing grooves adapted to the meshing rod. When the meshing part rotates in a predetermined direction, the meshing rod, under the action of a damper, abuts against the meshing groove, forming an effective transmission engagement, driving the first or second toothed ring to rotate synchronously. When the meshing part rotates in the opposite direction, the meshing rod can rotate flexibly relative to the meshing part and disengage from the meshing groove, eliminating reverse transmission resistance. This design allows the screwing part to quickly return to its initial position, thereby reducing the intensity of manual operation.

[0017] Furthermore, the meshing grooves of the two sets of gear rings are designed with opposite directions. When the operator drives the transmission unit through one set of screwing parts, the other set of gear rings and its corresponding screwing parts will not rotate accordingly, structurally avoiding motion interference between multiple transmission paths. This design not only ensures the transmission accuracy of a single adjustment path but also reduces ineffective friction and wear between mechanical parts, further improving the stability and reliability of the transmission process and extending the service life of the equipment.

[0018] In summary, this invention constructs a highly efficient and collaborative dual manual adjustment mechanism. By segmenting and controlling different turning parts, it can transmit differentiated rotational speeds to the output shaft, achieving step-by-step control of valve opening and closing speeds. This solves the core problems of existing technologies, such as limited manual control settings and limited applicability to various scenarios. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] As mentioned earlier, the manual control components of existing on / off valve actuators generally suffer from design limitations. Their manual mechanisms often employ a single-speed transmission structure, lacking a flexible speed adjustment mechanism. This means the valve's opening and closing speed is entirely determined by the operator's manual operation rate, making adaptive adjustments impossible based on actual operating conditions. In emergency situations requiring rapid response, the single-speed design struggles to achieve rapid valve opening and closing, potentially delaying fault handling and leading to severe damage to the pipeline system, thus impacting overall operational safety and reliability.

[0031] To address this issue, this utility model provides an actuator with a multi-functional design featuring dual manual operation. Applied to the field of valve operation, this mechanism transmits differentiated rotational speeds to the output shaft through segmented control of different turning parts, achieving step-wise control of valve opening and closing speeds. This solves the core problem of existing technologies where manual control offers only a single range of speeds and has limited applicability. This utility model achieves this solution through the following methods.

[0032] Example 1: Please refer to the accompanying drawings in the specification. This first embodiment provides a multifunctional switching valve actuator, which includes, for example: Figure 1 or Figure 2 The outer casing 1 is shown. Inside the outer casing 1, there is a... Figure 3 The drive source 15 shown (e.g., a motor, and the drive source 15 is controlled by a control module 12 located inside the housing 1) has a second convex shaft 63 fixedly connected to its output shaft. The second convex shaft 63 is rotatably connected to a bearing seat 13, which is fixed inside the housing 1. Simultaneously, a first convex shaft 62 is also connected to the housing 1 via the bearing seat 13, and the first convex shaft 62 is positioned corresponding to the second convex shaft 63. Both the first convex shaft 62 and the second convex shaft 63 have raised strips. A toggle groove 11 is provided on the top end face of the housing 1, and a toggle part 6 is provided within the toggle groove 11. A locking part 61 is rotatably connected to the toggle part 6 via a bearing. The locking part 61 has a locking groove, through which it engages with the raised strips on the first convex shaft 62 and the second convex shaft 63. The locking part 61 is slidably connected to the first convex shaft 62 and the second convex shaft 63. There is a distance between the first convex shaft 62 and the second convex shaft 63. The first cam 62 is connected to the transmission assembly, which is in turn connected to the output shaft 16 (the output shaft 16 is also rotatably connected to the housing 1 via the bearing 13).

[0033] Therefore, when the actuating part 6 slides within the actuating groove 11, the locking part 61 has at least the following states: In the first state, the locking part 61 is locked between the first cam 62 and the second cam 63. In this first state, when the drive source 15 drives the second cam 63 to rotate, it drives the first cam 62 to rotate via the locking part 61, and then transmits the power to the output shaft 16 via the transmission group, thereby realizing the opening and closing of the switch valve driven by the drive source 15.

[0034] In the second state, the engaging part 61 is disposed on the first convex shaft 62 and is not connected to the second convex shaft 63; or the engaging part 61 is disposed on the second convex shaft 63 and is not connected to the first convex shaft 62. In this second state, the transmission assembly is disengaged from the drive source 15.

[0035] In this first embodiment, as Figures 3 to 5As shown, the transmission assembly includes a worm 5 rotatably connected to a bearing 13, and a worm wheel 51 meshing with the worm 5. The worm wheel 51 is rotatably connected to the housing 1 via a wheel seat 14. One end of the worm 5 is fixedly connected to a first cam shaft 62, while the other end of the worm 5 is fixed with a first gear 23 and a second gear 33 (the first gear 23 and the second gear 33 are connected by a connecting rod 53, which is also fixed to the housing 1 via the bearing 13). Inside the housing 1, a first gear ring 22 and a second gear ring 32 are rotatably connected via the wheel seat 14. The first gear ring 22 meshes with the first gear 23. The second gear ring 32 meshes with the second gear 33. The first gear ring 22 and the second gear ring 32 are respectively connected to the first screwing part 2 and the second screwing part 3. The first gear 23 and the second gear 33 have different numbers of teeth.

[0036] Therefore, in the specific implementation of this embodiment, in the second state, the first screwing part 2 is screwed, which drives the first gear ring 22 to rotate. The rotation of the first gear ring 22 drives the first gear 23 to rotate, which in turn drives the worm 5 to rotate. The worm 5 transmits the rotation speed to the output shaft 16, so that the output shaft 16 opens and closes the valve at the first rotation speed.

[0037] Alternatively, the second screwing part 3 can be screwed on, which will drive the second gear ring 32 to rotate. The rotation of the second gear ring 32 will drive the second gear 33 to rotate, which in turn will drive the worm 5 to rotate. The worm 5 will transmit the rotation speed to the output shaft 16, so that the output shaft 16 can open and close the valve at the second rotation speed.

[0038] Example 2: Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment two. For example... Figure 8 As shown in this second embodiment, both the first toothed ring 22 and the second toothed ring 32 have meshing grooves 41, which are evenly distributed on the first toothed ring 22 and the second toothed ring 32 with the same orientation. Both the first toothed ring 22 and the second toothed ring 32 have meshing portions 4, and several meshing rods 42 are rotatably connected to the meshing portions 4. A damper 43 is rotatably connected to each meshing rod 42, with one end of the damper 43 away from the meshing rod 42 hinged to the meshing portion 4. The meshing rods 42 abut against the meshing grooves 41.

[0039] like Figure 6 As shown, in this second embodiment, a screwing rod 21 is fixed on the first screwing part 2, and the screwing rod 21 is fixedly connected to the meshing part 4 located inside the first toothed ring 22. A sleeve 31 is fixed on the second screwing part 3, and the sleeve 31 is rotatably connected to the outer shell 1 through a bearing. It is sleeved outside the screwing rod 21 and fixed to the meshing part 4 located inside the second toothed ring 32.

[0040] Therefore, in the specific implementation of this second embodiment, the first screwing part 2 is screwed on, which drives the meshing part 4 and its meshing rod 42 to rotate. The meshing rod 42 abuts against the meshing groove 41, thereby driving the first gear ring 22 to rotate. Thus, in the aforementioned embodiment, power is transmitted to the rotating shaft 16, causing it to rotate in the first direction. Until the switch valve is closed, after closing, screwing continues, and the valve inside the switch valve continues to rotate, thus opening again, and so on in a cycle. At this time, the transmission group simultaneously acts in the opposite direction on the second gear 33 through rotational force, driving the second gear ring 32 and the second screwing part 3 to rotate in the second direction.

[0041] When the first screwing part 2 rotates in the second direction, the meshing part 4 drives the meshing rod 42 to rotate. The meshing rod 42 rotates due to the contact of the meshing groove 41, and its position changes. It squeezes the damper 43 and disengages from the meshing groove 41. At this time, the meshing part 4 rotates, and the first toothed ring 22 remains stationary (the same applies to the second screwing part 3 and the second toothed ring 32, which will not be described in detail here).

[0042] Example 3: Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides Embodiment Three. For example... Figure 7 As shown, in this third embodiment, the meshing grooves 41 of the first toothed ring 22 and the second toothed ring 32 are distributed in opposite directions. For example, the meshing grooves 41 of the first toothed ring 22 are distributed in a second direction, and the meshing grooves 41 of the second toothed ring 32 are distributed in a first direction.

[0043] This means that when the first gear ring 22 rotates, the first gear 23 and the second gear 33 rotate synchronously, thereby meshing with the second gear ring 32 to rotate. Since their meshing grooves 41 are in opposite directions, the second gear ring 32 does not rotate when the first gear ring 22 rotates.

[0044] Therefore, in summary, compared with the prior art, this utility model and its embodiments have the following advantages, including but not limited to: This invention utilizes a first gear ring 22 and a second gear ring 32 to mesh with a first gear 23 and a second gear 33 to drive their rotation, which in turn transmits the rotational speed to the transmission assembly. The two independent geared transmission structures can each provide different speed outputs. In manual control scenarios, operators can independently select the appropriate speed mode and flexibly adjust the valve opening and closing rate according to actual working conditions. This satisfies both the rapid response requirements in emergency scenarios and the stable operation requirements in fine-tuning scenarios, ultimately achieving comprehensive adaptability to various application scenarios.

[0045] Meanwhile, the first toothed ring 22 and the second toothed ring 32 of this invention are internally equipped with a meshing part 4, and the meshing part 4 is rotatably connected to a meshing rod 42. The inner sides of the first toothed ring 22 and the second toothed ring 32 are provided with meshing grooves 41 that are adapted to the meshing rod 42. When the meshing part 4 rotates in a predetermined direction, the meshing rod 42 abuts against the meshing groove 41 under the action of the damper 43, forming an effective transmission engagement, driving the first toothed ring 22 or the second toothed ring 32 to rotate synchronously. When the meshing part 4 rotates in the opposite direction, the meshing rod 42 can rotate flexibly relative to the meshing part 4 and disengage from the meshing groove 41, eliminating reverse transmission resistance. This design allows the first screwing part 2 and the second screwing part 3 to quickly return to their initial positions, thereby reducing the intensity of manual operation.

[0046] Furthermore, the meshing grooves 41 of the first gear ring 22 and the second gear ring 32 are designed with opposite directions. When the operator drives the transmission group through one set of the first screwing part 2 or the second screwing part 3, the other set of gear rings and their corresponding screwing parts will not rotate accordingly, thus structurally avoiding motion interference between multiple transmission paths. This design not only ensures the transmission accuracy of a single adjustment path but also reduces ineffective friction and wear between mechanical parts, further improving the stability and reliability of the transmission process and extending the service life of the equipment.

[0047] In summary, this invention constructs a highly efficient and collaborative dual manual adjustment mechanism. By segmenting and controlling different first and second turning parts 2 and 3, differentiated rotational speeds can be transmitted to the output shaft 16, achieving step-by-step control of the valve opening and closing speed. This solves the core problems of existing technologies, such as limited manual control settings and limited adaptability to various scenarios.

[0048] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
