Description

Technical Field

[0001] This invention relates to the field of valve testing technology, and in particular to a multifunctional valve testing equipment system and method. Background Technology

[0002] During the testing of the control valve, a servo drive motor is used to directly rotate the external control handle of the control valve to perform the linearization test of the control valve.

[0003] However, during testing, the servo motor output shaft is directly connected to the central shaft of the adjustment handle. The servo motor requires a large torque to drive the adjustment handle to rotate, which places high demands on the output power of the servo motor (drive mechanism).

[0004] Currently, to test control valves of different specifications, a mechanical gripper is used to hold the control handle from the outside. Various sensors on the gripper determine if the handle is firmly held. Then, an external high-torque motor drives the gripper mechanism to rotate, thereby rotating the control handle. However, when the external high-torque motor drives the gripper mechanism, the range of angles that can be rotated by the mechanical-to-hydraulic and electrical connections is limited. Since many control valves have a large range of rotation angles, sometimes requiring several rotations, this rotation drive method is relatively unsuitable.

[0005] In summary, when testing control valves, the problem that needs to be solved is how to reduce the output power demand of the drive motor that drives the control valve to rotate, while still being able to complete the adjustment and rotation test process over a wide range of rotation angles. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a multifunctional valve testing equipment system and method, thereby reducing the requirements for the output power of the drive motor, improving the applicability of the testing equipment to regulating valves with different rotation angle requirements, and ensuring the comprehensiveness and accuracy of the test.

[0007] This invention provides a multifunctional valve testing equipment system, including a test station with a clamping fixture for positioning and holding valve components. Above the test station is a drive device for rotating the valve component's adjustment handle. The drive device includes a top plate, a movable shaft mounted on the upper side of the top plate, a moving drive device for moving the movable shaft, an inner plate mounted on the lower side of the top plate, multiple outer hooks rotatably engaging with the inner plate, suspension rings mounted on the lower ends of the multiple outer hooks, and an inner ring positioned within the suspension rings.

[0008] The inner disc assembly has two thrust bearing rings. One thrust bearing ring is positioned between the inner disc and the outer hook assembly, and the other thrust bearing ring is positioned between the outer hook assembly and the top disc assembly. The outer ring of the suspension ring has a toothed surface on its side, and the bottom side of the inner ring assembly has multiple handle sleeves that engage with the handle rod of the adjusting handle.

[0009] The top plate is fixedly equipped with multiple drive motors, and the output side of each drive motor is equipped with a drive gear that meshes with the gear ring surface. Multiple sensing and positioning components for detecting the handle's rotating rod are located in the central area on the lower side of the top plate.

[0010] As a preferred technical solution of the testing equipment system of the present invention: the inner disc component includes a bottom ring, an inner sleeve ring located on the upper side of the bottom ring, and two thrust bearing rings fitted around the outer side of the inner sleeve ring.

[0011] The outer hook component includes an arc-shaped vertical plate and an arc-shaped horizontal plate located at the upper end of the arc-shaped vertical plate. The arc-shaped horizontal plate is fitted between two thrust bearing rings.

[0012] As a preferred technical solution of the testing equipment system of the present invention: the handle sleeve has a groove structure that matches the size of the handle rotating rod.

[0013] As a preferred technical solution of the testing equipment system of the present invention: the inner circumference of the suspension ring is provided with an annular notch and an inner circular groove that vertically penetrates the suspension ring. The bottom side of the inner ring component is provided with a downwardly convex inner ring, and the inner ring component is provided with a photoelectric detection port that vertically penetrates the inner ring component. The bottom surface of the sensing positioning component is embedded with a photoelectric sensing probe, and the downward detection path of the photoelectric sensing probe passes through the photoelectric detection port area of ​​the inner ring component.

[0014] As a preferred technical solution of the testing equipment system of the present invention: the number of sensing and positioning components on the bottom side of the top plate component is the same as the number of handle sleeves on the bottom side of the inner ring component, and the positions of multiple sensing and positioning components are independently aligned with the multiple handle sleeves on the bottom side of the inner ring component.

[0015] As a preferred technical solution of the testing equipment system of the present invention: the drive motor is inverted and fixedly installed on the upper side of the top plate component, the drive motor is equipped with an output shaft, and the top plate component is equipped with an upper bearing that mates with the output shaft. Multiple ring-shaped support components located around the suspension ring are installed on the lower side of the top plate component, and each ring-shaped support component is equipped with a lower bearing that mates with the lower end of the output shaft.

[0016] As a preferred technical solution of the testing equipment system of the present invention: the ring support includes a support vertical plate and a support horizontal plate located at the lower end of the support vertical plate. The upper end of the support vertical plate is fixedly connected to the top plate by bolts, and the lower bearing is configured at the position of the support horizontal plate.

[0017] This invention provides a method for using a multifunctional valve testing equipment system, comprising the following:

[0018] S1. Fix the valve to be tested at the clamping fixture position on the test fixture.

[0019] S2. Multiple sensing and positioning elements on the bottom side of the top plate detect the obstruction signal status of the handle lever.

[0020] S2.1. If the occlusion signal status is abnormal, the moving drive device will drive the drive equipment to move horizontally or vertically until the occlusion signal status is normal. When the occlusion signal status is normal, multiple sensing positioning elements will be able to detect the occlusion signal of the handle lever.

[0021] S3. The moving drive device drives the drive equipment to descend until the torque of the moving drive device continues to increase. Then the moving drive device stops driving the drive equipment to descend. The continuous increase in torque indicates that the handle sleeve of the drive equipment has abutted against the handle lever.

[0022] S4. When the valve to be tested switches from the closed state to the open state: Start any one of the drive motors. When the output torque of the first drive motor gradually increases and reaches its peak value, start the second drive motor. When the output torque of the second drive motor gradually increases and reaches its peak value, start the third drive motor. Continue to start other drive motors in this way until the torque of the drive motor is lower than its peak value. Stop starting other drive motors. Accumulate and store the number of open drive motors and record it as N.

[0023] S5. When the valve to be tested switches from the open state to the closed state: Start any one of the drive motors. When the output torque of the first drive motor gradually increases and reaches its peak value, start the second drive motor. When the output torque of the second drive motor gradually increases and reaches its peak value, start the third drive motor, and so on, until the Nth drive motor starts and its torque reaches its peak value. Stop starting other drive motors. When the output speed of the drive motor drops to zero, after a system-preset delay time t, all drive motors are turned off.

[0024] Compared with existing technologies, the beneficial effects of this invention are:

[0025] 1. This invention changes the force transmission method by using a suspension ring, inner ring component, and handle sleeve to indirectly act on the adjustment handle, thus avoiding the huge torque required for the high-power motor to directly drive the central shaft of the handle. This significantly reduces the power requirements of the drive motor and reduces equipment energy consumption and cost.

[0026] 2. This invention utilizes multiple drive motors meshing with the suspension ring gear to drive the transmission, and through reasonable motor start-up sequence control, achieves stable and wide-range rotation angle adjustment during valve opening and closing, improving the applicability of the testing equipment to regulating valves with different rotation angle requirements, and ensuring the comprehensiveness and accuracy of the test.

[0027] 3. In this invention, the related structural design of the multiple sensing and positioning components and the inner ring component configured on the lower side of the top plate component can accurately detect the position and state of the handle lever, ensuring accurate docking and stable operation of the drive equipment and the adjustment handle, providing a reliable data acquisition and control basis for testing, effectively improving the accuracy and reliability of test results, and ensuring the quality of valve testing.

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0042] Example 1: This invention designs a multifunctional valve testing equipment system, with the following main configurations:

[0043] (i) Test station: such as Figure 1 As shown, the test stand 1 is the basic support structure of the entire testing equipment, used to place and fix the valve component 3. The clamping fixture 2 is installed on the test stand 1, and its function is to position and firmly clamp the valve component 3, ensuring that the valve component 3 will not shift during the test, thus guaranteeing the accuracy and stability of the test. In actual implementation, the clamping fixture 2 can be adapted to different valve components 3 according to their shape and size. For example, an adjustable jaw structure can be used, with the jaws opening and closing achieved through bolts or hydraulic devices to accommodate various specifications of valve components 3.

[0044] (ii) Top plate components: such as Figure 2 , Figure 8 As shown, the top plate 5 is an important component of the drive equipment, serving to connect and support other parts. It is fixedly equipped with multiple drive motors 12. These drive motors 12 do not require high power; they are inverted and fixedly mounted on the upper side of the top plate 5, and each is equipped with an output shaft 1201. The top plate 5 is equipped with an upper bearing 501 that mates with the output shaft 1201. During installation, it is essential to ensure that the drive motors 12 are securely installed and that the output shaft 1201 and the upper bearing 501 are tightly fitted to guarantee smooth rotation and torque transmission of the drive motors 12.

[0045] (iii) Moving shafts and moving drive devices: such as Figure 1 , Figure 2 , Figure 4 , Figure 6 As shown, the movable shaft 13 is mounted on the upper side of the top plate 5, and the movable drive device 15 is used to drive the movable shaft 13 to move, thereby realizing the adjustment and movement of the drive equipment in the horizontal, vertical, and longitudinal directions. The movable drive device 15 can be an existing three-dimensional motion platform or a three-degree-of-freedom Cartesian coordinate robot, etc. The structural design of the movable drive device 15 will not be described in detail in this invention. During implementation, it is necessary to select a suitable movable drive device 15 according to the test site and test accuracy requirements, and to perform precise installation and debugging to ensure that it can accurately control the position movement of the drive equipment, so that the drive equipment can accurately dock with the adjustment handle 4 of the valve component 3.

[0046] (iv) Internal components: such as Figure 2 , Figure 6 , Figure 7 , Figure 9 As shown, the inner disc component 6 is installed below the top disc component 5, and includes a bottom ring 601, an inner sleeve ring 602 located above the bottom ring 601, and two thrust bearing rings 8 fitted around the inner sleeve ring 602. The inner disc component 6 rotates with the outer hook component 7 and the top disc component 5 through the thrust bearing rings 8, reducing friction between components and ensuring the flexibility and stability of rotation. During assembly, attention should be paid to the installation position and orientation of the thrust bearing rings 8 to ensure that the outer hook component 7 can rotate smoothly.

[0047] (v) External hook parts: such as Figure 2 , Figure 6 , Figure 7 , Figure 9 As shown, the outer hook component 7 includes an arc-shaped vertical plate 701 and an arc-shaped horizontal plate 702 located on the upper end of the arc-shaped vertical plate 701. The arc-shaped horizontal plate 702 is fitted between the two thrust bearing rings 8. The outer hook component 7, together with the inner plate component 6 and the top plate component 5, constitutes a stable rotating structure. During installation, it is necessary to ensure the fitting accuracy between the arc-shaped horizontal plate 702 and the thrust bearing ring 8 to avoid loosening or jamming.

[0048] (vi) Suspension ring and inner ring components: such as Figure 2 , Figure 3 , Figure 5 , Figure 10 , Figure 11As shown, the suspension ring 9 is installed on the lower end of multiple outer hooks 7. Its outer ring side is a toothed ring surface 901, and its inner circumference has an annular notch 902 and an inner circular groove 903 that vertically penetrates the suspension ring 9. The inner ring 10 is positioned and installed inside the suspension ring 9. The bottom side of the inner ring 10 has a downwardly protruding inner ring 1001 and a photoelectric detection port 1002 that vertically penetrates the inner ring 10. Multiple handle sleeves 1003 are also arranged on the bottom side, and the handle sleeves 1003 cooperate with the handle rotation rod 401 of the adjusting handle 4. During installation, it is essential to ensure a secure connection between the inner ring 10 and the suspension ring 9, and that the groove structure of the handle sleeve 1003 precisely matches the size of the handle rotation rod 401 to accurately transmit torque. Simultaneously, the area of ​​the photoelectric detection port 1002 is large enough to meet the detection requirements of the sensing positioning component 14.

[0049] (vii) Drive motor and related components: such as Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 10 , Figure 12 As shown, the output side of the drive motor 12 is equipped with a drive gear 1202 that meshes with the gear ring surface 901. When the drive motor 12 rotates, the meshing transmission between the drive gear 1202 and the gear ring surface 901 drives the suspension ring 9 and the inner ring 10 to rotate, thereby indirectly driving the adjustment handle 4 of the valve component 3 to rotate. During installation, it is necessary to ensure the meshing accuracy between the drive gear 1202 and the gear ring surface 901 to guarantee the efficiency and stability of power transmission. Multiple ring-shaped support members 11 located around the suspension ring 9 are installed on the lower side of the top plate component 5. The ring-shaped support member 11 includes a support vertical plate 1101 and a support horizontal plate 1102 located at the lower end of the support vertical plate 1101. The lower bearing 1103 is arranged at the position of the support horizontal plate 1102. The upper end of the support vertical plate 1101 of the ring-shaped support member 11 is fixedly connected to the top plate component 5 by bolts. The lower bearing 1103 cooperates with the lower end of the output shaft 1201 of the drive motor 12 to further enhance the stability of the output shaft 1201 of the drive motor 12 and ensure that the drive motor 12 will not be displaced or shaken during operation.

[0050] (8) Sensing and positioning components: such as Figure 2 , Figure 3 , Figure 8 , Figure 10 , Figure 11As shown, multiple sensor positioning elements 14 are arranged in the central area of ​​the lower side of the top plate component 5. A photoelectric sensor probe 1401 is embedded in the bottom surface of each sensor positioning element 14. The downward detection path of the photoelectric sensor probe 1401 passes through the photoelectric detection port 1002 area of ​​the inner ring component 10. The number of sensor positioning elements 14 on the bottom side of the top plate component 5 is the same as the number of handle sleeves 1003 on the bottom side of the inner ring component 10. The positions of the multiple sensor positioning elements 14 are independently aligned with the multiple handle sleeves 1003 on the bottom side of the inner ring component 10. Before testing, the sensor positioning elements 14 need to be calibrated to ensure that they can accurately detect the obstruction signal state of the handle lever 401, providing reliable support for subsequent positioning and operation of the drive equipment.

[0051] Example 2: The installation process of the test equipment system of the present invention is as follows:

[0052] First, install the thrust bearing rings 8 onto the inner disc 6. Then, assemble the outer hook 7 between the two thrust bearing rings 8. The inner disc 6 is then fixed to the bottom side of the top disc 5 with bolts. In this step, pay attention to the installation sequence and direction of the thrust bearing rings 8, as well as the fitting accuracy between the outer hook 7, the thrust bearing rings 8, and the inner disc 6. Use appropriate tools for installation and adjustment, such as wrenches and screwdrivers, to ensure that all components are tightly connected.

[0053] Then, the inner ring 10, which is compatible with the adjusting handle 4 of the valve component 3 under test, is fixedly installed on the inner circumference of the suspension ring 9 with bolts, and the lower end of the outer hook 7 is fixed to the upper side of the suspension ring 9 with bolts. When installing the inner ring 10, a suitable inner ring 10 should be selected according to the specifications of the valve component 3, and its installation should be ensured to be secure. At the same time, check whether the connection between the outer hook 7 and the suspension ring 9 is secure to avoid loosening during the test.

[0054] Then, the annular support 11 is fixedly installed on the lower side of the top plate 5 using bolts. The upper end of the support vertical plate 1101 of the annular support 11 is fixedly connected to the top plate 5 by bolts. When installing the annular support 11, it is necessary to ensure that its installation position is accurate, the support vertical plate 1101 is tightly connected to the top plate 5, and the lower bearing 1103 is well fitted to the lower end of the output shaft 1201 of the drive motor 12.

[0055] Next, install the drive motor 12 on the top plate 5, and connect the output shaft 1201 of the drive motor 12 with the upper bearing 501 and the lower bearing 1103, and mesh the drive gear 1202 with the toothed ring surface 901 of the suspension ring 9. In this step, the installation position of the drive motor 12 must be carefully adjusted to ensure the fitting accuracy between the output shaft 1201 and the bearing, as well as the meshing accuracy between the drive gear 1202 and the toothed ring surface 901. Tools such as dial indicators can be used for measurement and adjustment to ensure that the drive motor 12 can work normally and effectively transmit power.

[0056] Example 3: The method of using the testing equipment system of the present invention is as follows:

[0057] S1. Valve component fixing: Fix the valve component 3 to be tested at the clamping fixture 2 position of the test fixture 1, ensuring that the valve component 3 is firmly installed and the adjusting handle 4 is in an operable state.

[0058] S2. Handle Rotary Rod Detection and Positioning: Multiple sensing and positioning elements 14 on the bottom side of the top plate 5 detect the obstruction signal status of the handle rotary rod 401. If the obstruction signal status is abnormal, the moving drive device 15 drives the drive equipment to move horizontally or vertically until the obstruction signal status is normal, that is, all multiple sensing and positioning elements 14 can detect the obstruction signal of the handle rotary rod 401. During this process, the position of the drive equipment should be adjusted in a timely manner according to the signals fed back by the sensing and positioning elements 14. Automated adjustment can be achieved through the control system to improve testing efficiency.

[0059] S3. Lowering and docking of the drive equipment: The mobile drive device 15 lowers the drive equipment until the torque of the mobile drive device 15 continuously increases. At this point, the mobile drive device 15 stops lowering the drive equipment, indicating that the handle sleeve 1003 of the drive equipment has abutted against the handle lever 401. During the descent, torque changes should be monitored in real time. Torque data can be monitored through a torque sensor to ensure the accuracy and reliability of the docking.

[0060] S4. Valve Opening Test: When the valve 3 under test switches from the closed state to the open state, start any one of the drive motors 12. When the output torque of the first drive motor 12 gradually increases and reaches its peak, start the second drive motor 12. When the output torque of the second drive motor 12 gradually increases and reaches its peak, start the third drive motor 12, and so on, continuously starting other drive motors 12 until the torque of the drive motor 12 is lower than its peak value. Then stop starting other drive motors 12. The number of open drive motors 12 is accumulated, stored, and recorded as N. During this process, to accurately monitor the starting sequence and torque changes of the drive motors 12, automated control and monitoring can be achieved through a motor controller and torque sensor to record accurate test data.

[0061] S5. Valve Closure Test: When the valve component 3 under test switches from the open state to the closed state, start any one of the drive motors 12. When the output torque of the first drive motor 12 gradually increases and reaches its peak value, start the second drive motor 12. When the output torque of the second drive motor 12 gradually increases and reaches its peak value, start the third drive motor 12, and so on, until the Nth drive motor 12 starts and its torque reaches its peak value. Then, stop starting other drive motors 12. When the output speed of the drive motor 12 drops to zero, after a system-preset delay time t, all drive motors 12 close. Similarly, the closing process must be strictly operated according to the prescribed steps. The control system achieves automated control to ensure the accuracy and reliability of the test results.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

The mobile driving device (15) drives the driving device to descend until the torque of the mobile driving device (15) continues to increase, and the mobile driving device (15) stops driving the driving device to descend; S4. When the valve piece (3) to be tested is switched from the closed state to the open state: start any one of the driving motors (12), the output torque of the first driving motor (12) gradually increases and reaches the peak value, then start the second driving motor (12), the output torque of the second driving motor (12) gradually increases and reaches the peak value, then start the third driving motor (12), in this way, other driving motors (12) are started in sequence, until the torque of the driving motor (12) is lower than the peak value, stop starting other driving motors (12), the number of opened driving motors (12) is accumulated, stored and recorded as N; S5. When the valve piece (3) to be tested is switched from the open state to the closed state: start any one of the driving motors (12), the output torque of the first driving motor (12) gradually increases and reaches the peak value, then start the second driving motor (12), the output torque of the second driving motor (12) gradually increases and reaches the peak value, then start the third driving motor (12), until the Nth driving motor (12) is started and the torque reaches the peak value, stop starting other driving motors (12), when the output speed of the driving motor (12) decreases to zero, after a delay time t preset by the system, all driving motors (12) are turned off.
