Description

Technical Field

[0001] This invention relates to the field of electric valve torque detection technology, specifically to a method and apparatus for detecting the torque of marine electric valves. Background Technology

[0002] Electric valves typically consist of an electric actuator and a valve body. They use electrical energy to power the electric actuator, which in turn drives the valve to open and close. This achieves the purpose of controlling the flow of media in the pipeline. Once the valve is selected, choosing a suitable electric actuator is crucial for ensuring its safe and normal operation. An inappropriate actuator selection can not only affect performance but also lead to serious adverse consequences and economic losses. Therefore, torque testing of electric valves is necessary.

[0003] The conventional testing method involves connecting the drive shaft of the electric valve actuator to the flange of the testing device and then using a torque sensor for detection. A common problem with this method is that different models of electric valves have different shaft dimensions, requiring alignment of the testing device's shaft with the rotating shaft during installation. Furthermore, for electric valves used in ships, conventional testing cannot accurately measure torque because environmental factors such as temperature, humidity, air pressure, magnetic fields, mechanical shock, vibration, and dust can affect the function of the electric valve and consequently its torque. These environmental factors can lead to a decline in the performance of the electric valve. Therefore, for electric valves used in ships, it is also necessary to eliminate interference from environmental factors. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a method and apparatus for detecting the torque of marine electric valves to solve the problems mentioned in the background. The present invention features a novel structure, with the actuator mounted on an installation assembly. A positioning assembly ensures that the rotating shaft and the connecting shaft are aligned. After the connecting shaft and the rotating shaft are connected, three tests are performed at different temperatures and humidity levels, both outside and inside the testing box, to simulate the marine environment and detect the torque magnitude. This method is more convenient to use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a torque detection device for a marine electric valve, comprising a base platform, a detection box fixed at the top center of the base platform, and a mounting seat at one end of the base platform near the detection box, on which a rotating device is mounted. An installation assembly is located on the other side of the base platform near the detection box. The installation assembly includes a base plate with a moving groove, and two clamping plates symmetrically and slidably mounted within the moving groove. An actuator is clamped between the base plate and the two clamping plates, and a rotating shaft is located at the end of the actuator facing the detection box. A connecting shaft is mounted at the output end of the rotating device, and a flange is fixed at the end of the connecting shaft that passes through the detection box. A torque sensor is mounted at the rear end of the connecting shaft near the flange. A positioning assembly is located between the connecting shaft and the rotating shaft, comprising a rotating ring rotatably sleeved on the connecting shaft. Connecting plates are located on the upper and lower sides of the rotating shaft, and an arc block is located on the middle surface of the connecting plate. The arc block of the connecting plate slides in contact with the rotating shaft. A display screen is mounted on the outer surface of the detection box.

[0006] Furthermore, the testing box has two sliding doors installed at one end facing the mounting assembly, and a bidirectional electric push rod is fixed to the top of the testing box. The two extended ends of the bidirectional electric push rod are fixedly connected to the two doors. A humidity regulating device is fixedly installed on the inner wall of the top of the testing box, and a temperature control device is installed on the inner walls of both sides of the testing box. Two sensor assemblies are installed on the inner wall of the top of the testing box on both sides of the humidity regulating device, and the sensor assemblies are a temperature sensor and a humidity sensor, respectively.

[0007] Furthermore, the installation assembly also includes telescopic frames, with two telescopic frames fixed on both sides of the bottom of the base plate, and a one-way electric push rod fixed to the outer end of the telescopic frames. The extended end of the one-way electric push rod is fixedly connected to the base plate. A first bidirectional screw is rotatably installed in the moving groove through a bearing, and the bottom threads of the two clamping plates are threaded onto both ends of the first bidirectional screw.

[0008] Furthermore, two sliding grooves are formed on the surface of the base, and the bottom of the telescopic frame and the mounting base slide along the sliding grooves. A lead screw is rotatably installed inside the sliding grooves through bearings. A first motor is fixed at one end of the base, and the output end of the first motor is fixedly connected to the lead screw. The bottom of the mounting base is threaded onto the surface of the lead screw, and the bottom of the telescopic frame slides along the outer surface of the lead screw.

[0009] Furthermore, the positioning component also includes a vertical plate, the bottom of the rotating ring is fixed with the vertical plate, and a connecting frame is fixed on the surface of the vertical plate. A horizontal frame is slidably sleeved on the outer surface of the connecting frame. A mounting bracket is fixed at one end of the horizontal frame located on the rotating shaft, and the two connecting plates are slidably sleeved on the mounting bracket at both ends.

[0010] Furthermore, a second bidirectional screw is rotatably mounted on both sides of the mounting bracket via bearing seats. A second motor is fixedly mounted on the top of the second bidirectional screw, and the output end of the second motor is fixedly connected to the second bidirectional screw. The connecting plate is threaded onto the surface of the second bidirectional screw.

[0011] Furthermore, a socket is fixed on the side surface of the connecting frame facing the mounting bracket, and a drive shaft is rotatably mounted on the bottom of the mounting bracket via a bearing. A horizontal plate is fixed to the front end of the drive shaft, and a third motor is fixed to the outer end of the horizontal frame. The output end of the third motor is fixedly connected to the drive shaft.

[0012] Furthermore, the outer surface of the socket is provided with a slot, and the slot allows the horizontal plate and drive shaft to be inserted. The interior of the socket is provided with a circular groove, and the horizontal plate can pass through the slot and enter the circular groove.

[0013] Furthermore, a movable notch is provided on the back of the detection box corresponding to the position of the horizontal frame, and a sliding sleeve is fixed at the position where the connecting shaft passes through the detection box, with the connecting shaft passing through the inside of the sliding sleeve.

[0014] A method for detecting the torque of a ship's electric valve, the method comprising the following steps:

[0015] (1) Positioning installation: Install the actuator of the electric valve on the mounting assembly, and insert the rotating shaft of the actuator into the positioning assembly. Adjust the rotating shaft to be in the same straight line as the connecting shaft through the positioning assembly;

[0016] (2) Butt installation: The rotating device and the connecting shaft slide along the base platform, and the flange end of the connecting shaft is fixedly installed after being mated with the rotating shaft;

[0017] (3) Ordinary detection: On the outside of the detection box, the connecting shaft and the rotating shaft are driven to rotate by the rotating device. The torque of the rotating shaft is detected by the torque sensor and the torque is calculated.

[0018] (4) Temperature and humidity regulation detection: The rotating device pulls the actuator into the detection box. The temperature and humidity inside the detection box are adjusted by the temperature control device and the humidity regulation device to create the environment where the ship is located. The torque sensor detects the torque change of the rotating shaft under different environments and transmits the data to the display screen.

[0019] The beneficial effects of this invention are:

[0020] As the horizontal plate continues to penetrate deeper into the circular groove, the third motor drives the drive shaft to rotate, causing the horizontal plate to rotate into a vertical position, misaligning with the original slot and engaging inside the socket. Subsequently, when the lead screw drives the mounting base to move, it can pull the mounting components and actuator into the testing chamber. During the process, the rotating shaft will not separate from the flange, which facilitates the installation of the connecting shaft and the rotating shaft, and also makes it convenient to send the actuator into the testing chamber for torque testing under different temperatures and humidity conditions.

[0021] In this invention, the centers of the two connecting plate arc blocks and the center of the rotating ring are on the same straight line. After the actuator is installed, the rotating shaft is inserted between the two connecting plates. The second motor can drive the second bidirectional screw to rotate. The height of the installation component can be adjusted by the unidirectional electric push rod to meet the rotation insertion of different sizes. Then, the two connecting plates limit the position of the rotating shaft to keep the connecting shaft and the rotating shaft on the same straight line, which facilitates subsequent docking and installation and saves calibration time. When performing torque testing, the connecting plates are far away from the rotating shaft to avoid interfering with the rotation of the rotating shaft.

[0022] This invention uses a first bidirectional screw to rotate, causing two clamping plates to slide along the moving groove in a threaded engagement with the first bidirectional screw, thereby clamping and fixing both sides of the actuator. The height of the base plate is raised by a unidirectional electric push rod and a telescopic frame, thus satisfying the installation and fixing of electric valve actuators of different models and sizes.

[0023] Compared with the prior art, the present invention has an actuator mounted on the mounting assembly, which uses a positioning assembly to make the rotating shaft and the connecting shaft collinear. After the connecting shaft and the rotating shaft are connected, three tests are performed at different temperatures and humidity levels, one outside the test box and one inside the test box, to simulate the ship environment and detect the magnitude of the torque, making it more convenient to use.

When using the device, the actuator 4 is installed on the mounting assembly 5, and the rotating shaft 41 and the connecting shaft 32 are adjusted to be on the same axis by the positioning assembly 6. The first motor 12 is turned on to drive the lead screw 13 to rotate, driving the mounting base 3 and the rotating device 31 to move. The rotating device 31 can be a drive motor. After the connecting shaft 32 is close to the rotating shaft 41, it is fixed by the flange 34. Then, the rotating shaft 41 is tested in three modes: normal state, humidity adjustment and temperature adjustment, so as to detect the torque of the electric valve suitable for use in ships.

[0040] In this embodiment, the detection box 2 has two sliding doors 22 mounted on one end facing the mounting assembly 5, and a bidirectional electric push rod 23 is fixed to the top of the detection box 2. The two extended ends of the bidirectional electric push rod 23 are fixedly connected to the two doors 22. A humidity regulating device 24 is fixedly mounted on the inner wall of the top of the detection box 2, and a temperature control device 26 is mounted on the inner walls of both sides of the detection box 2. Two sensor assemblies 25 are mounted on the inner wall of the top of the detection box 2 on both sides of the humidity regulating device 24, and the sensor assemblies 25 are a temperature sensor and a humidity sensor, respectively. The back of the detection box 2 corresponds to the position of the horizontal frame 61. The test chamber 2 is provided with a movable notch 27. A sliding sleeve 28 is fixed at the position where the connecting shaft 32 passes through, and the connecting shaft 32 passes through the inside of the sliding sleeve 28. When the actuator 4 is inserted, the bidirectional electric push rod 23 opens the two chamber doors 22. The chamber doors 22 are closed again when testing is performed. The temperature and humidity inside the test chamber 2 are adjusted by the temperature device and the humidity control device 24. The temperature and humidity changes are detected by the temperature sensor 25 and the humidity sensor 25, thereby simulating the torque of the actuator 4 on the ship's environment. The temperature device and the humidity control device 24 can be existing air conditioners and humidifiers.

[0041] In this embodiment, the mounting assembly 5 further includes a telescopic frame 52. Two telescopic frames 52 are fixed on both sides of the bottom of the base plate 51, and a one-way electric push rod 53 is fixed to the outer end of the telescopic frame 52. The extended end of the one-way electric push rod 53 is fixedly connected to the base plate 51. A first bidirectional screw 56 is rotatably mounted in the moving groove 55 through a bearing. The bottom threads of the two clamping plates 54 are threaded onto the two ends of the first bidirectional screw 56. Two sliding grooves 11 are formed on the surface of the base platform 1, and the bottoms of the telescopic frame 52 and the mounting base 3 slide along the sliding grooves 11. A lead screw is rotatably mounted in the sliding groove 11 through a bearing. 13. A first motor 12 is fixed at one end of the base 1, and the output end of the first motor 12 is fixedly connected to the lead screw 13. The bottom of the mounting base 3 is threaded onto the surface of the lead screw 13. The bottom of the telescopic frame 52 slides along the outer surface of the lead screw 13. The actuator 4 is placed on the base plate 51. When the first bidirectional screw 56 is rotated, the two clamping plates 54 are threadedly engaged with the first bidirectional screw 56 and slide along the moving groove 55 to clamp and fix the two sides of the actuator 4. The height of the base plate 51 is raised by the unidirectional electric push rod 53 and the telescopic frame 52, thereby satisfying the installation and fixing of electric valve actuators 4 of different models and sizes.

[0042] In this embodiment, the positioning component 6 further includes a vertical plate 63. The bottom of the rotating ring 62 is fixed with the vertical plate 63, and a connecting frame 67 is fixed on the surface of the vertical plate 63. A horizontal frame 61 is slidably sleeved on the outer surface of the connecting frame 67. A mounting bracket 64 is fixed at one end of the horizontal frame 61 located on the rotating shaft 41. The two connecting plates 65 are slidably sleeved on the mounting bracket 64 at both ends. A second bidirectional screw 66 is rotatably mounted on both sides of the mounting bracket 64 through bearing seats. A second motor 69 is fixed on the top of the second bidirectional screw 66 located on the mounting bracket 64, and the output end of the second motor 69 is fixedly connected to the second bidirectional screw 66. The connecting plate 65 is threadedly sleeved on the second bidirectional screw 66. On the surface of the screw 66, the centers of the arc blocks of the two connecting plates 65 and the center of the swivel ring 62 are on the same straight line. After the actuator 4 is installed, the rotating shaft 41 is inserted between the two connecting plates 65. The second bidirectional screw 66 can be rotated by the second motor 69. The height of the mounting assembly 5 can be adjusted by the unidirectional electric push rod 53 to meet the rotation insertion of different sizes. Then, the two connecting plates 65 limit the position of the rotating shaft 41, keeping the connecting shaft 32 and the rotating shaft 41 on the same straight line, which facilitates subsequent docking and installation and saves calibration time. When performing torque testing, the connecting plates 65 are kept away from the rotating shaft 41 to avoid interfering with the rotation of the rotating shaft 41.

[0043] In this embodiment, a socket 68 is fixed on the side surface of the connecting frame 67 facing the mounting bracket 64. The horizontal frame 61 is located at the bottom of the mounting bracket 64 and a drive shaft 612 is rotatably mounted on it via a bearing. A horizontal plate 613 is fixed to the front end of the drive shaft 612. A third motor 610 is fixed to the outer end of the horizontal frame 61, and the output end of the third motor 610 is fixedly connected to the drive shaft 612. A slot 614 is provided on the outer surface of the socket 68, and the slot 614 allows the horizontal plate 613 and the drive shaft 612 to be inserted. A circular groove 611 is provided inside the socket 68, and the horizontal plate 613 can pass through the slot 614 and enter the circular groove 611. When the connecting shaft 32 moves toward the rotating shaft 41, the rotating ring 62 on its surface drives the vertical plate 63 and the connecting frame 67 to slide along the horizontal frame 61 until the horizontal plate 63 moves toward the rotating shaft 41. Plate 613 and drive shaft 612 are inserted into socket 68. At this time, flange 34 can be connected and fixed to rotating shaft 41. The outermost slot 614 of socket 68 can accommodate the insertion of plate 613 and drive shaft 612. As plate 613 continues to penetrate into circular groove 611, third motor 610 drives drive shaft 612 to rotate. Plate 613 rotates to a vertical position, misaligning with the original slot 614 and engaging inside socket 68. When screw 13 drives mounting base 3 to move, mounting assembly 5 and actuator 4 can be pulled into test chamber 2. During the process, rotating shaft 41 will not separate from flange 34. This facilitates the installation of connecting shaft 32 and rotating shaft 41, and also makes it convenient to send actuator 4 into test chamber 2 for torque testing at different temperatures and humidity.

[0044] When using the device, the actuator 4 is placed on the base plate 51. Rotating the first bidirectional screw 56 causes the two clamping plates 54 to slide along the moving groove 55 in threaded engagement with the first bidirectional screw 56, clamping and fixing the actuator 4 on both sides. The height of the base plate 51 is raised by the unidirectional electric push rod 53 and the telescopic frame 52, thus accommodating the installation and fixing of electric valve actuators 4 of different models and sizes. The second motor 69 drives the second bidirectional screw 66 to rotate, and the height of the mounting assembly 5 is adjusted by the unidirectional electric push rod 53 to accommodate rotational insertion of different sizes. Then, the two connecting plates 65 limit the position of the rotating shaft 41, keeping the connecting shaft 32 and the rotating shaft 41 on the same straight line. The first motor 12 is turned on, driving the lead screw 13 to rotate, which in turn drives the mounting base 3 and the rotating device 31 to move. After the connecting shaft 32 approaches the rotating shaft 41, it passes through the flange 34. The outermost slot 614 of the socket 68 is fixed to accommodate the insertion of the horizontal plate 613 and the drive shaft 612. As the horizontal plate 613 continues to penetrate deeper into the circular groove 611, the third motor 610 drives the drive shaft 612 to rotate. The horizontal plate 613 rotates to a vertical position, misaligning with the original slot 614 and engaging inside the socket 68. When the lead screw 13 drives the mounting base 3 to move, it can pull the mounting assembly 5 and the actuator 4 into the testing box 2. During the process, the rotating shaft 41 will not separate from the flange 34. This facilitates the installation of the connecting shaft 32 and the rotating shaft 41, and also makes it convenient to send the actuator 4 into the testing box 2 for torque testing under different temperatures and humidity. Subsequently, the rotating shaft 41 is tested in three modes: normal state, humidity regulation, and temperature regulation, to facilitate the testing of the torque of electric valves suitable for marine use.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
