Description

Technical Field

[0001] This utility model relates to the field of valve control technology, and in particular to an explosion-proof intelligent positioner. Background Technology

[0002] Explosion-proof smart positioners are key actuators used in industrial automation for precise valve opening control, and are widely used in hazardous locations such as petroleum and chemical industries where explosive gas atmospheres exist. In practical applications, to ensure production stability and safety, smart positioners need to be regularly inspected, calibrated, or replaced if faulty.

[0003] Existing explosion-proof smart positioners typically feature a controller body securely fixed to a support frame with multiple bolts. Electrical connections require opening a dedicated junction box, threading cables through sealed connectors, and connecting them one by one to internal terminals. The power output is also connected to the valve switch via fasteners. While this high-strength fastening design ensures reliable connections and explosion-proof performance, it also makes disassembly and assembly extremely cumbersome. During on-site maintenance, workers must carry multiple tools to sequentially disassemble the fasteners used for mechanical fixation, electrical connections, and power transmission. This time-consuming process not only reduces maintenance efficiency but also extends equipment downtime, impacting production continuity.

[0004] Therefore, this utility model proposes an explosion-proof intelligent locator to overcome the shortcomings of the prior art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an explosion-proof intelligent positioner, which aims to improve the problem that the mechanical fixing, electrical connection and power transmission parts of the existing explosion-proof intelligent positioner adopt non-quick disassembly and assembly structure, resulting in a cumbersome, time-consuming and tool-dependent on-site disassembly and maintenance process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An explosion-proof intelligent positioner includes a flanged ball valve, a controller, a receiver, a support frame, a quick-release connector, a mechanical quick-release mechanism, and an electrical connector.

[0008] The receiver and controller are integrated into one unit and are mechanically connected to the support frame for quick separation via a quick-release mechanism. The controller establishes a quick-release power connection with the flanged ball valve via a quick-release connector and achieves a quick electrical connection via an electrical connector.

[0009] The mechanical quick-release mechanism includes a fixed base fixed to a support frame, a sliding rod connected to a controller or receiver and selectively inserted into the fixed base, a first magnet disposed on the sliding rod, and a second magnet disposed on the fixed base. The first magnet and the second magnet lock the sliding rod by repulsive magnetic force.

[0010] The electrical connector includes a first plug and a second plug. The first plug is provided with a rotating locking point, and the second plug is provided with a limiting guide rail that cooperates with the rotating locking point.

[0011] Preferably, the quick-release connector adopts a plug-in structure.

[0012] Preferably, the end of the sliding rod is connected to a handle for easy pulling operation.

[0013] Preferably, the sliding rod drive is connected to a limit rod, which can rotate and slide within the fixed seat.

[0014] Preferably, the electrical connector further includes a rotary sealing cap, which is rotatably fitted onto the first plug or the second plug for locking the two plugs together after they are inserted.

[0015] Preferably, the first plug is integrated into the housing of the controller or receiver.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem in the prior art that the controller and support frame are usually fastened with bolts, which is cumbersome to disassemble and assemble, relies on tools and is time-consuming. It achieves the effect of quick mechanical separation and locking of the controller and support frame without tools, which significantly improves the convenience of installation and maintenance.

[0018] 2. This utility model solves the problem that electrical connections in the prior art usually require disassembling the junction box and wiring one by one, which is complicated, error-prone and inefficient. It achieves the effect of quick alignment and locking of electrical interfaces by simply plugging, unplugging and rotating, which simplifies on-site operation and improves connection reliability.

[0024] 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.

[0025] Reference Figures 1-3 The present invention provides an embodiment of an explosion-proof intelligent positioner, which includes a flanged ball valve 1, a controller 3, a receiver 4, and a support frame 2. The receiver 4 and the controller 3 are integrated into one unit. The support frame 2 is used to support the controller 3 and the receiver 4. The flanged ball valve 1 has a valve switch 7. The controller 3 establishes a power connection with the valve switch 7 through a quick-release connector 6, thereby realizing the opening degree control of the flanged ball valve 1.

[0026] This quick-release mechanical mechanism is used to achieve rapid mechanical separation between the controller 3 and receiver 4 and the support frame 2. It includes a fixed base 10 fixed on the support frame 2, a sliding rod 11 connected to the controller 3 or receiver 4 and selectively inserted into the fixed base 10, a first magnet 14 disposed on the sliding rod 11, and a second magnet 15 disposed on the fixed base 10. When it is necessary to fix the controller 3 and receiver 4 to the support frame 2, the sliding rod 11 is inserted into the fixed base 10. At this time, the first magnet 14 and the second magnet 15 generate a repulsive magnetic force due to the opposing magnetic poles. This magnetic force firmly locks the sliding rod 11 in the fixed base 10, thereby completing the quick fixed installation of the controller 3 and receiver 4. Conversely, when it is necessary to disassemble, the sliding rod 11 can be pulled to overcome the magnetic repulsion force to achieve quick separation.

[0027] This electrical connector is used to achieve a quick electrical connection of the controller 3. It includes a first plug 8 and a second plug 9. The first plug 8 is integrated into the housing of the controller 3 or receiver 4. The first plug 8 is provided with a rotating locking point 16, and the second plug 9 is provided with a limiting guide rail 17 that cooperates with the rotating locking point 16. When making an electrical connection, the first plug 8 is aligned with the second plug 9 and inserted. The first plug 8 is rotated so that the rotating locking point 16 slides along the limiting guide rail 17 and locks in place, thus completing the quick connection of the electrical interface.

[0028] The quick-release connector 6 is used to establish a power connection that can be quickly disconnected between the controller 3 and the valve switch 7. The quick-release connector 6 adopts a plug-in structure. When installing or removing the controller 3, the quick-release connector 6 can be directly inserted or pulled out to establish or disconnect the power connection without removing the fasteners.

[0029] In a preferred embodiment, to facilitate the operation of the mechanical quick-release mechanism, a handle 12 is fixedly connected to the end of the sliding rod 11. The sliding rod 11 can be easily pulled out and inserted by operating the handle 12. To further improve the flexibility and adaptability of the installation, the sliding rod 11 is also driven to connect a limiting rod 13, which can rotate and slide freely inside the fixed base 10.

[0030] In a preferred embodiment, to enhance the stability and sealing of the electrical connector connection, the electrical connector further includes a rotating sealing cap 5, which is rotatably fitted onto the first plug 8 or the second plug 9. After the first plug 8 and the second plug 9 are connected through the rotating locking point 16 and the limiting guide rail 17, the rotating sealing cap 5 can be tightened to securely lock the two together.

[0031] Working principle: When the controller 3 or receiver 4 needs to be maintained or replaced and needs to be removed from the support frame 2 and flange ball valve 1, firstly, rotate the sealing cap 5 in the opposite direction to loosen the lock. Then, rotate the first plug 8 relative to the second plug 9 so that the rotation point 16 is released from the constraint of the limit guide rail 17, and the first plug 8 can be pulled out, thereby quickly completing the separation of the electrical interface. Next, the operator pulls the handle 12 in the opposite direction to drive the sliding rod 11 to overcome the magnetic repulsion between the first magnet 14 and the second magnet 15 and pull it out from the fixed seat 10. This action releases the mechanical fixing relationship between the controller 3 and receiver 4 and the support frame 2. At the same time as the controller 3 and receiver 4 are separated from the support frame 2, the quick-release connector 6 with the plug-in structure is also released from the valve switch 7, thereby realizing the disconnection of the power connection. Through the synergistic effect of the above mechanical quick-release mechanism, electrical connector and quick-release connector 6, the entire control unit can be quickly disassembled without tools, which greatly improves the operation and maintenance efficiency. The installation process is the reverse operation of the above steps.

[0032] At the same time, after the first plug 8 is inserted into the second plug 9 via the rotating locking point 16 and the limiting guide rail 17, the rotating sealing cap 5 is quickly locked, which can quickly complete the alignment and separation of the electrical interface without disassembling the fasteners one by one, thereby realizing the quick disassembly of the controller 3, which is convenient for subsequent maintenance, repair or replacement.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
