Description

Technical Field

[0001] This application relates to the field of valve technology, and more specifically, to a valve performance diagnostic wiring mechanism and a valve performance diagnostic device. Background Technology

[0002] Valve diagnostics refers to the process of testing valve performance by installing various electrical, mechanical, and pneumatic sensors on the electric and pneumatic actuators of electrically driven or pneumatic valves installed in the system, with minimal disassembly or disassembly. Valve diagnostic testing instruments and software are then used to test the relevant characteristic parameters of the valves. During valve diagnostic testing, signals such as the three-phase current, limit switch signals, torque switch signals, and torque bypass switch signals of the valve's electric actuator need to be collected.

[0003] Currently, there are two methods for acquiring signals during valve diagnostics: disconnecting the wiring and using a clamp. Disconnecting the wiring carries the potential risks of incorrect removal and reinstallation, as well as insecure reinstallation. These risks can damage the electric actuator motor or the valve body, resulting in significant human and property losses. The clamp method eliminates the need for disconnecting the wiring, but only a few electric actuators (such as the Bernard-ST type) can be used without disassembly. Most electric actuators (such as the Bernard-SN and Yangxiu types) cannot utilize the clamp method due to design limitations. Utility Model Content

[0016] The second mounting plate is detachably connected to the connection between the side wall and the second connecting wall, and the male plug portion protrudes from the side of the second connecting wall away from the side wall.

[0031] To provide a clearer understanding of the technical features, objectives, and effects of this application, the specific embodiments of this application are now described in detail with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0032] In the description of this application, it should be understood that the terms "longitudinal", "lateral", "up", "down", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, 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. Therefore, they should not be construed as limitations on this application.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0035] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0036] Figure 1 and Figure 2 The present application shows a valve performance diagnostic wiring mechanism 1 in one embodiment, which can be used in conjunction with a drive control switch mechanism 2 and a valve diagnostic acquisition mechanism 3 to perform performance diagnostic testing on a valve electric actuator 4.

[0037] It is necessary to understand that, such as Figure 4 As shown, the drive control switch mechanism 2 can drive the switch of the valve electric actuator 4, and includes a signal and power source 201. The valve electric actuator 4 includes a test electric head 401, which can be electrically connected to the signal and power source 201. After the two are electrically connected, the drive control switch mechanism 2 can realize the drive control of the valve electric actuator 4. (See also...) Figure 3 The valve diagnostic acquisition mechanism 3 includes a current clamp 301, which can acquire signals such as three-phase current, limit switch signal, torque switch signal, and torque bypass switch by clamping the connecting wire (current wire).

[0038] The valve performance diagnostic wiring mechanism 1 can be located between the drive control switch mechanism 2 and the valve electric actuator 4. It may include a frame 10, a female connector 20, a male connector 30, and multiple connecting wires 40. The female connector 20 and male connector 30 are respectively mounted on the frame 10. The female connector 20 can be electrically connected to the electric actuator 401 under test of the valve electric actuator 4, and the male connector 30 can be electrically connected to the signal and power source 201 of the drive control switch mechanism 2.

[0039] Multiple connecting wires 40 are detachably disposed between the female plug 20 and the male plug 30, with both ends of each connecting wire 40 electrically connected to pins on the female plug 20 and the male plug 30, respectively. At least one through-hole 131 can be formed on the frame 10, which exposes the connecting wires 40 between the female plug 20 and the male plug 30. The current clamp 301 of the valve diagnostic acquisition mechanism 3 can clamp the connecting wires 40 through the through-hole 131, achieving electrical connection with the connecting wires 40 through the clamping operation.

[0040] During valve diagnostic testing, the drive control switch mechanism 2 drives the valve electric actuator 4 to switch via the electrical connection of the valve performance diagnostic wiring mechanism 1. During this process, electrical signals are transmitted through the connecting line 40. At this time, the current clamp 301 of the valve diagnostic acquisition mechanism 3, by clamping the connecting line 40, can acquire the signals.

[0041] It should be understood that the number of the connecting wires 40 needs to be flexibly set according to the number of pins required by the female plug 20 and male plug 30 in the specific valve diagnosis and testing operation. It can be equal to the number of pins on the female plug 20 / male plug 30, or it can be less than the number of pins on the female plug 20 / male plug 30. No specific limit is made here.

[0042] The male plug 30 and female plug 20 in this application enable the valve performance diagnostic wiring mechanism 1 to be installed as a connection structure between the drive control switch mechanism 2 and the valve electric actuator 4, thereby achieving electrical connection between the two and ensuring that the drive control switch mechanism 2 can drive the valve electric actuator 4 normally.

[0043] Meanwhile, this application provides multiple connecting wires 40 between the male plug 30 and the female plug 20, and through holes 131 on the frame 10. This allows for both basic electrical connection and exposure of the connecting wires 40, enabling the current clamp 301 of the valve diagnostic acquisition mechanism 3 to clamp and connect them. Regardless of the type of valve the connected electric actuator 4 is, signal acquisition can be achieved.

[0044] This setup allows for valve diagnostic testing of various types of valves without requiring disassembly or dismantling of the valve's electric actuator 4, or disconnection of the wiring. It is universally applicable, simplifies the valve diagnostic testing process, avoids potential risks such as wiring errors during operation, and improves the efficiency and safety of valve diagnostic testing.

[0045] like Figure 2 As shown, in some embodiments, the frame 10 may include a first connecting wall 11, a second connecting wall 12, and a side wall 13. The first connecting wall 11 and the second connecting wall 12 are annular and spaced apart. The side wall 13 is cylindrical, with its two ends connected to the inner periphery of the first connecting wall 11 and the inner periphery of the second connecting wall 12, respectively.

[0046] exist Figure 2In the illustrated embodiment, the first connecting wall 11 and the second connecting wall 12 are arranged parallel to each other and spaced apart. Both have rectangular outer peripheries and circular inner peripheries. The side wall 13 is a cylindrical structure extending through both ends, perpendicular to both the first connecting wall 11 and the second connecting wall 12, with its two ends connected to the circular inner peripheries of the first connecting wall 11 and the second connecting wall 12, respectively. The through hole 131 is formed on the side wall 13.

[0047] In some other optional embodiments, the outer contours of the first connecting wall 11 and the second connecting wall 12 can also be circular, polygonal, irregular, or other shapes, and the inner contours can also be rectangular, polygonal, irregular, or other shapes. The shapes of the inner and outer contours can be the same or different. The shapes of the first connecting wall 11 and the second connecting wall 12 can be the same or different. The side wall 13 can be adjusted according to the inner contour shapes of the first connecting wall 11 and the second connecting wall 12, and it can also be connected to the outer periphery of the first connecting wall 11 and the second connecting wall 12 respectively.

[0048] In some other alternative embodiments, the first connecting wall 11 and the second connecting wall 12 may be positioned in a non-parallel, spaced-apart manner. For example, the first connecting wall 11 and the second connecting wall 12 may be arranged at a certain angle, and some of their side edges may be connected to each other.

[0049] In some other alternative embodiments, the frame 10 may be arranged in a relatively closed hollow box shape, with the male plug 30 and female plug 20 respectively located on different side walls of the frame 10, and the connecting wire 40 located in the hollow cavity of the box-shaped frame 10 and exposed through the through hole 131.

[0050] In some embodiments, the female plug 20 is detachably disposed on the side end of the frame 10 near the first connecting wall 11, and the male plug 30 is detachably disposed on the side end of the frame 10 near the second connecting wall 12.

[0051] This arrangement allows the female plug 20 and the male plug 30 to be positioned roughly on opposite sides of the frame 10. During the electrical connection with the drive control switch mechanism 2 and the valve electric actuator 4, the drive control switch mechanism 2 and the valve electric actuator 4 can be positioned roughly at opposite ends of the frame 10, providing a more flexible installation position and avoiding collisions and space occupation between the mechanisms during the connection process.

[0052] Furthermore, the first connecting wall 11 can be detachably connected to the valve electric actuator 4, and the second connecting wall 12 can be detachably connected to the drive control switch mechanism 2.

[0053] By setting the first connecting wall 11 and the second connecting wall 12, the stability of the valve performance diagnostic wiring mechanism 1 in electrical connection with the signal and power source 201 and the electric head under test 401 can be improved.

[0054] exist Figure 2 In the embodiment shown, the first connecting wall 11 and the second connecting wall 12 are respectively provided with a plurality of connecting holes. The first connecting wall 11 can be bolted to the valve electric actuator 4 through the connecting holes, and the second connecting wall 12 can be bolted to the drive control switch mechanism 2 through the connecting holes.

[0055] In some embodiments, the frame 10 further includes a first mounting plate 14 and a second mounting plate 15. The first mounting plate 14 is detachably disposed on the side end of the frame 10 near the first connecting wall 11, and the second mounting plate 15 is detachably disposed on the side end of the frame 10 near the second connecting wall 12. The female plug 20 is disposed on the first mounting plate 14, and the male plug 30 is disposed on the second mounting plate 15.

[0056] It is important to understand that the number and configuration of ports on the electric head 401 under test differ for different valve electric actuators 4, thus requiring a compatible female connector 20. By using the first mounting plate 14 and the second mounting plate 15, the versatility of the frame 10 can be improved. During valve performance testing of different valve electric actuators 4, it is unnecessary to frequently replace the entire valve performance diagnostic wiring mechanism 1; only the first mounting plate 14, the second mounting plate 15, and their female and male connectors 20 and 30 need to be removed and replaced, thereby reducing costs.

[0057] exist Figure 1 In the illustrated embodiment, the first mounting plate 14 is a circular plate with a diameter adapted to the inner diameter of the side wall 13, and is detachably disposed at the end of the side wall 13 near the first connecting wall 11. The first mounting plate 14 also has a first mounting hole (not shown in the figure), the shape of which is adapted to the female plug 20 so that the female plug 20 can pass through it. The second mounting plate 15 is also a circular plate with a diameter adapted to the inner diameter of the side wall 13, and is detachably disposed at the end of the side wall 13 near the second connecting wall 12. The second mounting plate 15 also has a second mounting hole (not shown in the figure), the shape of which is adapted to the male plug 30 so that the male plug 30 can pass through it.

[0058] It should be understood that the first and second assembly holes are respectively connected to the cavity in the side wall 13, so that the connecting wire 40 can be connected to the female plug 20 and the male plug 30 respectively, while the whole is located in the cavity of the cylindrical side wall 13 and can be exposed through the through hole 131.

[0059] In some other alternative embodiments, the shapes of the first mounting plate 14 and the second mounting plate 15 may also be inconsistent with the inner contour shape (cross-sectional shape of the sidewall 13) of the first connecting wall 11 / second connecting wall 12.

[0060] In some embodiments, the frame 10 is provided with a plurality of ear plates (not shown in the figure), and the first mounting plate 14, the second mounting plate 15 and the ear plates are respectively provided with connection holes. By means of connecting parts such as bolts, the first mounting plate 14 and the second mounting plate 15 can be detachably bolted to the frame 10 through the ear plates.

[0061] In some other alternative embodiments, the first mounting plate 14 and the second mounting plate 15 can also be connected to the frame 10 by welding or integral molding.

[0062] In some embodiments, the ear plate is disposed on the inner wall surface of the side wall 13, and the first mounting plate 14 is disposed between the first connecting wall 11 and the second connecting wall 12 via the ear plate in the extension direction of the axis of the side wall 13, and is disposed parallel to and spaced apart from the first connecting wall 11 and the second connecting wall 12. The spacing between the first mounting plate 14 and the first connecting wall 11 in the extension direction of the axis of the side wall 13 is such that the end of the female plug 20 away from the male plug 30 is approximately flush with the wall surface of the first connecting wall 11.

[0063] It should be understood that the electric head 401 under test of the valve electric actuator 4 is a male plug that is compatible with the female plug 20, and it protrudes from the end face of the valve electric actuator 4. The recessed design of the female plug 20 in this application facilitates the simultaneous detachable connection of the first connecting wall 11 to the valve electric actuator 4 and the insertion (electrical connection) of the female plug 20 into the electric head 401 under test.

[0064] The phrase "the end of the female plug 20 that is away from the male plug 30 is roughly flush with the wall surface of the first connecting wall 11" means that the end of the female plug 20 that is away from the male plug 30 may also be slightly recessed or protruding from the wall surface of the first connecting wall 11.

[0065] It is important to understand that the specific relative positional relationship between the end of the female plug 20 away from the male plug 30 and the first connecting wall 11 needs to be flexibly set according to the size of the female plug 20 and the size of the electric head 401 to be tested, with the ultimate goal of achieving "the first connecting wall 11 and the valve electric actuator 4 can be detachably connected in place, while the female plug 20 can be plugged into (electrically connected) in place with the electric head 401 to be tested".

[0066] In some embodiments, a portion of the ear plate is disposed on the inner wall surface of the side wall 13 and located at the connection between the side wall 13 and the second connecting wall 12. The second mounting plate 15 is detachably connected to the connection between the side wall 13 and the second connecting wall 12 via the ear plate, and the male plug 30 is partially protruding from the side of the second connecting wall 12 opposite to the side wall 13.

[0067] It should be understood that the signal and power source 201 of the drive control switch mechanism 2 is a female plug that is compatible with the male plug 30, and it is recessed into the end face of the valve electric actuator 4. The protruding male plug 30 in this application facilitates the detachable connection of the second connecting wall 12 and the drive control switch mechanism 2, while the male plug 30 can be plugged into (electrically connected) with the signal and power source 201.

[0068] The size of the male plug 30 protruding from the side of the second connecting wall 12 away from the side wall 13 needs to be adapted to the size of the recess of the signal and power source 201 in the drive control switch mechanism 2 to which it is adapted, and no specific limitation is made here.

[0069] In some embodiments, the female plug 20 can be detachably connected to the first mounting plate 14 by means of bolts, and the male plug 30 can be detachably connected to the second mounting plate 15 by means of bolts.

[0070] In some other alternative embodiments, the female plug 20 may also be fixed to the first mounting plate 14, and the male plug 30 may also be fixed to the second mounting plate 15.

[0071] In some embodiments, the number of through holes 131 on the sidewall 13 can be at least two, and they can be evenly spaced in the circumferential direction of the sidewall 13 so that multiple connecting wires 40 can flexibly select the adjacent through hole 131 to be led out according to their connection position with the pins of the male plug 30 and the female plug 20.

[0072] Different pins on the male plug 30 and female plug 20 can transmit different signals, so the multiple through holes 131 also facilitate the classification of the connecting wires 40. During the connection process of the valve performance diagnostic wiring mechanism 1, connecting wires 40 transmitting the same signal type can be led out from the same through hole 131. This arrangement facilitates clamping by the current clamp 301 and avoids potential clamping errors.

[0073] Specifically, there can be three through holes 131, which are arranged in parallel intervals. Each through hole 131 is roughly rectangular in shape, with its length extending circumferentially along the sidewall 13 and its width parallel to the axial direction of the sidewall 13.

[0074] In some other alternative embodiments, the number of through holes 131 can also be set to two, four, five, or other plurality of numbers. The shape of the through holes 131 can also be set to other shapes such as circles, ellipses, polygons, or irregular shapes.

[0075] In some embodiments, the position of the through hole 131 in the axial direction of the side wall 13 is adapted to the gap position between the female plug 20 and the male plug 30.

[0076] exist Figure 2 In the embodiment shown, since the first mounting plate 14 is located between the first connecting wall 11 and the second connecting wall 12, and the second mounting plate 15 is located at the connection between the second connecting wall 12 and the side wall 13, the rectangular through hole 131 is positioned closer to the second connecting wall 12 in the axial direction of the side wall 13.

[0077] Furthermore, the length of the through hole 131 in the direction of extension of the side wall 13 axis is adapted to the distance between the female plug 20 and the male plug 30 in the direction of extension of the side wall 13 axis.

[0078] In some other alternative embodiments, the location and size of the through hole 131 can be independent of the location of the male plug 30 and the female plug 20, and can be flexibly set on the side wall 13.

[0079] like Figure 3 As shown, this application also constructs a valve performance diagnostic device, which can perform performance diagnostic testing on the valve electric actuator 4.

[0080] The valve performance diagnostic device may include a drive control switch mechanism 2, a valve diagnostic acquisition mechanism 3, and a valve performance diagnostic wiring mechanism 1 as described in any of the preceding embodiments. The male plug 30 of the valve performance diagnostic wiring mechanism 1 can be electrically connected to the signal and power source 201 of the drive control switch mechanism 2, and the female plug 20 of the valve performance diagnostic wiring mechanism 1 can be electrically connected to the electric head 401 under test of the valve electric actuator 4. The drive control switch mechanism 2 can drive the switch of the valve electric actuator 4 through the valve performance diagnostic wiring mechanism 1.

[0081] The current clamp 301 of the valve diagnostic acquisition mechanism 3 is detachably clamped and electrically connected to the connection line 40 of the valve performance diagnostic wiring mechanism 1 for information acquisition.

[0082] It should be understood that the drive control switch mechanism 2 can be implemented using existing valve drive control switch instruments or control loops in the original system where the valve is located, or other valve drive control equipment. Similarly, the valve diagnostic acquisition mechanism 3 can also be implemented using existing valve diagnostic acquisition instruments or other signal diagnostic acquisition equipment.

[0083] Understandably, the above-mentioned technical features can be used in any combination without restriction.

[0084] The above embodiments merely illustrate specific implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this application's patent. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of this application, and can also make several modifications and improvements, all of which fall within the protection scope of this application. Therefore, any equivalent transformations and modifications made within the scope of the claims of this application should be covered by the claims of this application.
