Description

Technical Field

[0001] This utility model belongs to the field of fluid valve technology, and in particular relates to a combinable and quick-installation electric valve actuator. Background Technology

[0002] In industrial production, the integrated installation of automatic valves and actuators is a crucial step in achieving precise control. Traditionally, valves and actuators are connected using bolted flanges, but this method suffers from the following drawbacks: 1. High operational complexity: It requires tools for tightening multiple bolts, making on-site assembly time-consuming and demanding on operator skills, especially in confined spaces or high-risk environments where efficiency is significantly reduced; 2. Dynamic sealing risks: Traditional rigid connection structures are prone to stress concentration under vibration, leading to fatigue failure of sealing elements and the risk of media leakage; 3. Insufficient modular expansion: Existing fixed assembly solutions struggle to support rapid reconfiguration of actuators, failing to meet the dynamic switching requirements of flexible production lines for multi-condition execution configurations. In recent years, some improved solutions have attempted to reduce assembly and disassembly difficulty using snap-fit ​​joints or pre-tensioning springs, but these still suffer from technical bottlenecks such as insufficient axial positioning accuracy and weak torque resistance. Utility Model Content

Detailed Implementation

[0025] 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.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1:

[0028] Reference Figure 1 This utility model provides a combinable and quick-assembly electric valve actuator, including an actuator 3 and a valve 4, and further including:

[0029] Actuator connector 1, with a first inner hole for the valve stem to pass through, one end of actuator connector 1 is detachably connected to actuator 3, and a first centering limit component is provided between actuator connector 1 and actuator 3;

[0030] Valve connector 2 has a second inner hole for the valve stem to pass through. One end of valve connector 2 is detachably connected to valve 4. The other end of valve connector 2 is provided with a second centering limit component between it and actuator connector 1. A fixing connector is also provided between valve connector 2 and actuator connector 1.

[0031] The main function of actuator connector 1 is to quickly align with the interface of actuator 3 and fix it to actuator 3; the main function of valve connector 2 is to quickly connect with the interface of valve 4; actuator connector 1 and valve connector 2 achieve quick alignment through a second alignment limiting component, thereby ensuring that actuator 3 and valve 4 are in an aligned state; the main function of the fixing connector is to achieve a fixed connection between actuator 3 and valve 4 by connecting actuator connector 1 and valve connector 2. Overall, after connecting the actuator connector and valve connector to the actuator and valve respectively, this utility model can connect the actuator connector and valve connector simply by operating the fixing connector, making the connection operation simple. At the same time, by adding actuator connector and valve connector, a rigid connection between actuator and valve is avoided. Furthermore, by only changing the structure of actuator connector and valve connector, various connections between actuators and valves can be achieved, demonstrating strong scalability.

[0032] In a further optimized design, a first threaded hole 5 is provided on the side wall of the actuator connector 1 near the actuator 3. A first screw 6 is fitted inside the first threaded hole 5. The threaded end of the first screw 6 penetrates the side wall of the actuator 3 and is fixedly connected to the first threaded hole 5.

[0033] A first sealing ring 7 abuts against the inner wall of the actuator 3 between the first screw 6 and the first screw 6.

[0034] like Figure 1 As shown, the actuator connector 1 and the actuator 3 can be fixedly connected by the first screw 6. The main function of the first sealing ring 7 is to ensure the sealing of the actuator 3.

[0035] The scheme is further optimized. The first centering limit component includes a first centering groove 8 opened at the end of the actuator connector 1. The first centering groove 8 is set close to the actuator 3. It also includes a first positioning sub-port 9 opened on the side wall of the actuator 3. The first centering groove 8 and the first positioning sub-port 9 are adapted to each other.

[0036] In a further optimized design, the first centering limit component also includes a first positioning pin 10. The actuator connector 1 near the actuator 3 and the actuator 3 near the actuator connector 1 are respectively provided with first pin holes 11, and the first positioning pin 10 is inserted between the two first pin holes 11.

[0037] like Figure 1 As shown, by inserting the first positioning port 9 into the first alignment groove 8, it can be ensured that the first inner hole of the actuator connector 1 and the inner hole of the actuator 3 are aligned, ensuring smooth rotation of the valve stem between the actuator 3 and the valve 4. The main function of the first positioning pin 10 is to ensure that there is no rotation between the actuator connector 1 and the actuator 3 before fixing with the first screw 6, which facilitates subsequent operation.

[0038] To further optimize the design, a second threaded hole 12 is provided on the side wall of valve 4 near valve joint 2. A second screw 13 is fitted inside the second threaded hole 12. The threaded end of the second screw 13 passes through valve joint 2 and is fixedly connected to the second threaded hole 12.

[0039] like Figure 1 As shown, the valve connector 2 and the valve 4 can be fixedly connected by the second screw 13.

[0040] Further optimization of the scheme: the second centering limit component includes a second centering groove 15 opened at the end of the actuator connector 1 away from the valve 4, and a second positioning port 16 opened on the side wall of the valve connector 2 near the actuator 3. The second centering groove 15 and the second positioning port 16 are adapted to each other.

[0041] In a further optimized design, the second centering limit assembly also includes a second positioning pin 17. The actuator connector 1 and the valve connector 2 are respectively provided with second pin holes 18 on the side away from the valve 4, and the second positioning pin 17 is inserted between the two second pin holes 18.

[0042] like Figure 1 As shown, by inserting the second positioning port 16 into the second alignment groove 15, it can be ensured that the first inner hole of the actuator connector 1 and the inner hole of the valve connector 2 are aligned. The main function of the second positioning pin 17 is to ensure that there is no rotation between the actuator connector 1 and the valve connector 2 before fixing with the second screw 13, which facilitates subsequent operation.

[0043] Further optimization of the scheme: the fixed connection component includes a connecting lock nut 19, which is rotatably sleeved on the valve joint 12. The outer wall of the actuator joint 1 is provided with a threaded section, and the connecting lock nut 19 is adapted to the threaded section of the actuator joint 1.

[0044] like Figure 1 As shown, a limiting surface is provided on the inner bottom of the connecting lock nut 19, allowing the connecting lock nut 19 to be rotatably fitted onto the valve connector 2. After connecting the valve connector 2 to the actuator connector 1, the operator only needs to rotate the connecting lock nut 19. Since there is a second locating pin 17 between the valve connector 2 and the actuator connector 1 to limit relative rotation, the internal thread of the connecting lock nut 19 can engage with the external thread of the actuator connector 1, achieving final locking.

[0045] Example 2:

[0046] The only difference between this embodiment and Embodiment 1 is that the actuator connector 1 and the actuator 3 are integrally formed.

[0047] like Figure 2As shown, during the connection process, the operator only needs to first fix the valve connector 2 and the valve 4 with the second screw 13, then fix the actuator connector 1 part to the valve connector 2 with the second positioning pin 17, and finally fix the actuator 3 and the valve 4 by tightening the connecting lock nut 19.

[0048] Example 3:

[0049] The only difference between this embodiment and Embodiment 1 is that the first centering limiting component is connected to the second centering limiting component to form the third centering limiting component, which can further simplify the quick-assembly structure.

[0050] like Figure 3 As shown, the third limiting centering component includes an integrated positioning pin 20. A through groove 21 is provided between the top and bottom surfaces of the actuator connector 1. A third pin hole 22 is provided on the side of the actuator 3 near the actuator connector 1 and on the side of the valve connector 2 away from the valve 4. The positioning pin 20 passes through the through groove 21 and its two ends are respectively inserted into the two third pin holes 22.

[0051] Example 4:

[0052] In this embodiment, as Figure 4 As shown, four sets of anti-rotation protrusions 23 are fixedly connected at equal intervals at the bottom of the actuator connector 1, and four sets of anti-rotation grooves 24 are equally spaced on the top of the valve connector 2. When the actuator connector 1 is installed on the valve connector 2, by inserting the four sets of anti-rotation protrusions 23 into the four sets of anti-rotation grooves 24, it can be ensured that the actuator connector 1 and the valve connector 2 are at the correct angle.

[0053] Further optimize the plan, such as Figure 5 As shown, two sets of anti-rotation protrusions 23 at the bottom of actuator connector 1 and anti-rotation grooves 24 at the top of valve connector 2 can be provided to play an anti-rotation role.

[0054] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
