Description

Technical Field

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

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

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

[0004] In order to test regulating valves of different specifications, a mechanical claw is used to clamp the regulating handle from the outside, and various sensors of the mechanical claw are used to determine whether the column handle is firmly clamped, and then the mechanical claw mechanism is driven to rotate by an external high-torque motor, thereby driving the regulating handle to rotate. However, when the external high-torque motor drives the mechanical claw mechanism to rotate, it is limited by the mechanical-hydraulic and electrical connection structure, and the angle range that can drive the regulating handle to rotate is limited. The rotation angle range of many regulating valves is very large, and even requires several turns. The applicability of this rotation drive method is relatively poor.

[0005] In summary, when testing the regulating valve, how to reduce the output power requirement of the driving motor that drives the regulating valve to rotate, while being able to complete the adjustment rotation test process of a large range of rotation angles, becomes a problem that needs to be solved.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0042] Embodiment 1: The present invention designs a multifunctional valve testing equipment system, the main configuration of which is as follows:

[0043] 1. Test fixture: Figure 1 As shown, the test fixture 1 is the basic support structure of the entire test equipment, which is used to place and fix the valve component 3. The clamping fixture 2 is installed on the test fixture 1, and its function is to position and firmly clamp the valve component 3 to ensure that the valve component 3 will not be displaced during the test process, thereby ensuring the accuracy and stability of the test. In actual implementation, the clamping fixture 2 can be adapted according to the shape and size of different valve components 3, for example, an adjustable clamping jaw structure is used to open and close the clamping jaw through bolts or hydraulic devices to adapt to valve components 3 of various specifications.

[0044] ㈡Top plate: such as Figure 2 , Figure 8 As shown, the top plate 5 is an important component of the driving device, which plays the role of connecting and supporting other components. It is fixedly configured with multiple driving motors 12. The driving motors 12 do not need to be high-power motors. The driving motors 12 are inverted and fixedly installed on the upper side of the top plate 5, and are configured with an output shaft 1201. The top plate 5 is configured with an upper bearing 501 that matches the output shaft 1201. During installation, it is necessary to ensure that the driving motor 12 is firmly installed, and the output shaft 1201 and the upper bearing 501 are tightly matched to ensure that the driving motor 12 can rotate smoothly and transmit torque.

[0045] ㈢Moving shaft and moving drive device: such as Figure 1 , Figure 2 , Figure 4 , Figure 6 As shown, the moving shaft 13 is installed on the upper side of the top plate 5, and the moving drive device 15 is used to drive the moving shaft 13 to move, so as to realize the adjustment and movement of the driving device in the horizontal, longitudinal and vertical directions. The moving drive device 15 can adopt an existing three-dimensional motion platform or a three-degree-of-freedom rectangular coordinate manipulator, etc., and the structural design of the moving drive device 15 is not repeated in the present invention. In the implementation process, it is necessary to select a suitable moving drive device 15 according to the test site and the test accuracy requirements, and to perform precise installation and debugging to ensure that it can accurately control the position movement of the driving device, so that the driving device can accurately dock with the adjustment handle 4 of the valve member 3.

[0046] ㈣Inner plate: such as Figure 2 , Figure 6 , Figure 7 , Fig. 9 As shown, the inner disc 6 is installed on the lower side of the top disc 5, including a bottom ring 601, an inner sleeve ring 602 located on the upper side of the bottom ring 601, and two thrust bearing rings 8 are sleeved on the outer periphery of the inner sleeve ring 602. The inner disc 6, the outer hook 7 and the top disc 5 are rotated together through the thrust bearing ring 8 to reduce the friction between the components and ensure the flexibility and stability of the rotation. During assembly, attention should be paid to the installation position and direction of the thrust bearing ring 8 to ensure that the outer hook 7 can rotate smoothly.

[0047] ㈤External hook: such as Figure 2 , Figure 6 , Figure 7 , Fig. 9 As shown, the outer hook member 7 includes an arc-shaped vertical plate 701 and an arc-shaped horizontal plate 702 located at the upper side of the arc-shaped vertical plate 701. The arc-shaped horizontal plate 702 is inserted between the two thrust bearing rings 8. The outer hook member 7, the inner plate member 6 and the top plate member 5 together form a stable rotating structure. During the installation process, the matching accuracy of the arc-shaped horizontal plate 702 and the thrust bearing ring 8 must be ensured to avoid looseness or jamming.

[0048] ㈥Suspension ring and inner ring: such as Figure 2 , Figure 3 , Figure 5 , Fig.10 , Fig.11As shown, the suspension ring 9 is installed at the lower side of multiple outer hooks 7, and the outer ring side is a toothed ring surface 901, and the inner circumference is provided with 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 in the inner circumference of the suspension ring 9, and the bottom side of the inner ring 10 is provided with a downward convex inner circular ring 1001, and a photoelectric detection port 1002 that vertically penetrates the inner ring 10 is provided, and the bottom side is provided with multiple handle sleeves 1003, and the handle sleeves 1003 are matched with the handle rotating rod 401 of the adjustment handle 4. During installation, it is necessary to ensure that the inner ring 10 is firmly connected to the suspension ring 9, and the notch structure of the handle sleeve 1003 is precisely matched with the size of the handle rotating rod 401, so as to accurately transmit torque. At the same time, the area size of the photoelectric detection port 1002 is large enough to meet the detection requirements of the sensor positioning member 14.

[0049] ㈦Drive motor and related parts: such as Figure 1 , Figure 2 , Figure 4 , Figure 6 , Fig.10 , Fig.12 As shown, the output side of the driving motor 12 is provided with a driving gear 1202 meshing with the toothed ring surface 901. When the driving motor 12 rotates, the meshing transmission between the driving gear 1202 and the toothed ring surface 901 drives the suspension ring 9 and the inner ring member 10 to rotate, thereby indirectly driving the adjustment handle 4 of the valve member 3 to rotate. During the installation process, the meshing accuracy between the driving gear 1202 and the toothed ring surface 901 must be ensured to ensure the high efficiency and stability of power transmission. A plurality of annular support members 11 located at the periphery of the suspension ring 9 are installed on the lower side of the top plate 5. The annular support member 11 includes a supporting vertical plate 1101 and a supporting horizontal plate 1102 located at the lower end of the supporting vertical plate 1101. The lower bearing 1103 is arranged at the position of the supporting horizontal plate 1102. The upper end of the supporting vertical plate 1101 of the annular support member 11 is fixedly connected to the top plate 5 by bolts. The lower bearing 1103 cooperates with the lower end of the output shaft 1201 of the drive motor 12, thereby further enhancing the stability of the output shaft 1201 of the drive motor 12 and ensuring that the drive motor 12 will not be displaced or shaken during operation.

[0050] ㈧Sensor positioning parts: such as Figure 2 , Figure 3 , Figure 8 , Fig.10 , Fig.11As shown, a plurality of sensor positioning members 14 are arranged in the central area of ​​the lower side of the top plate 5, and a photoelectric sensor probe 1401 is embedded in the bottom surface of the sensor positioning member 14. The downward detection path of the photoelectric sensor probe 1401 passes through the photoelectric detection port 1002 area of ​​the inner ring member 10, and the number of sensor positioning members 14 on the bottom side of the top plate 5 is the same as the number of handle sleeves 1003 on the bottom side of the inner ring member 10, and the positions of the plurality of sensor positioning members 14 are independently aligned with the plurality of handle sleeves 1003 on the bottom side of the inner ring member 10. Before testing, the sensor positioning member 14 needs to be calibrated to ensure that it can accurately detect the blocking signal state of the handle rotating rod 401, and provide reliable support for the subsequent positioning and operation of the driving device.

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

[0052] First, the thrust bearing ring 8 is mounted on the inner disc 6, the outer hook 7 is assembled between the two thrust bearing rings 8, and the inner disc 6 is fixed to the bottom side of the top disc 5 by bolts. In this step, attention should be paid to the installation sequence and direction of the thrust bearing ring 8, as well as the matching accuracy of the outer hook 7, the thrust bearing ring 8 and the inner disc 6. Appropriate tools such as wrenches and screwdrivers can be used for installation and adjustment to ensure that all components are tightly connected.

[0053] Then, the inner ring 10 that matches the adjustment handle 4 of the valve member 3 to be tested is fixed to the inner periphery of the suspension ring 9 by bolts, and the lower end of the outer hook 7 is fixed to the upper side of the suspension ring 9 by bolts. When installing the inner ring 10, select the appropriate inner ring 10 according to the specifications of the valve member 3 and ensure that it is firmly installed. At the same time, check whether the connection between the outer hook 7 and the suspension ring 9 is stable to avoid looseness during the test.

[0054] Then, the annular support 11 is fixedly installed on the lower side of the top plate 5 by bolts, and the upper side end of the support vertical plate 1101 of the annular support 11 is fixedly connected with 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 with the top plate 5, and the lower bearing 1103 is well matched with the lower side end of the output shaft 1201 of the drive motor 12.

[0055] Then, the drive motor 12 is installed on the top plate 5, and the output shaft 1201 of the drive motor 12 is matched and connected with the upper bearing 501 and the lower bearing 1103, and the drive gear 1202 is meshed with the toothed ring surface 901 of the suspension ring 9. In this step, the installation position of the drive motor 12 should be carefully adjusted to ensure the matching accuracy of the output shaft 1201 and the bearing, and the meshing accuracy of the drive gear 1202 and the toothed ring surface 901. The dial indicator and other tools can be used for measurement and adjustment to ensure that the drive motor 12 can work normally and effectively transmit power.

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

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

[0058] S2. Detection and positioning of the handle rotating rod: The multiple sensor positioning members 14 on the bottom side of the top plate 5 detect the blocking signal status of the handle rotating rod 401 downward. If the blocking signal status is abnormal, the mobile driving device 15 drives the driving device to move horizontally or vertically until the blocking signal status is normal, that is, the multiple sensor positioning members 14 can detect the blocking signal of the handle rotating rod 401. In this process, the position of the driving device should be adjusted in time according to the signal fed back by the sensor positioning member 14, and automatic adjustment can be achieved through the control system to improve the test efficiency.

[0059] S3. Driving device descends and docks: The mobile driving device 15 drives the driving device to descend until the torque of the mobile driving device 15 continues to increase, and then the mobile driving device 15 stops driving the driving device to descend, which means that the handle sleeve 1003 of the driving device has abutted against the handle rotating rod 401. During the descent process, the torque change should be monitored in real time, and the torque data can be monitored by a torque sensor to ensure the accuracy and reliability of the docking.

[0060] S4. Valve opening test: When the valve member 3 to be tested 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 the peak value, start the second drive motor 12. When the output torque of the second drive motor 12 gradually increases and reaches the peak value, start the third drive motor 12. In this way, other drive motors 12 are started continuously until the torque of the drive motor 12 is lower than the peak value. Then stop starting other drive motors 12, and accumulate, store and record the number of open drive motors 12 as N. In this process, the start-up sequence and torque change of the drive motor 12 must be accurately monitored. Automatic control and monitoring can be achieved through the motor controller and torque sensor to record accurate test data.

[0061] S5. Valve closing test: When the valve member 3 to be tested 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 the peak value, start the second drive motor 12. When the output torque of the second drive motor 12 gradually increases and reaches the peak value, start the third drive motor 12. Until the Nth drive motor 12 starts and the torque reaches the peak value, stop starting other drive motors 12. When the output speed of the drive motor 12 drops to zero, after the delay time t preset by the system, all drive motors 12 are turned off. Similarly, during the closing process, the prescribed steps must be strictly followed, and automatic control must be achieved through the control system to ensure the accuracy and reliability of the test results.

When the valve member (3) to be tested is switched from a closed state to an open state: start any one of the drive motors (12), and when the output torque of the first drive motor (12) gradually increases and reaches a peak value, start the second drive motor (12), and when the output torque of the second drive motor (12) gradually increases and reaches a peak value, start the third drive motor (12), and in this way, continuously start the other drive motors (12) until the torque of the drive motor (12) is lower than the peak value, stop starting the other drive motors (12), and accumulate and store the number of the opened drive motors (12) and record it as N; S5. When the valve member (3) to be tested switches from an open state to a closed state: start any one of the drive motors (12). When the output torque of the first drive motor (12) gradually increases and reaches a peak value, start the second drive motor (12). When the output torque of the second drive motor (12) gradually increases and reaches a peak value, start the third drive motor (12). This process continues until the Nth drive motor (12) is started and the torque reaches a peak value. Stop starting other drive motors (12). When the output speed of the drive motor (12) drops to zero, all drive motors (12) are turned off after a delay time t preset by the system.
