Description

Technical Field

[0001] The present invention relates to the technical field of ball valve detection, and particularly to a ball valve abrasion resistance detection device and its usage method. Background Art

[0002] In the industrial field and numerous pipeline systems, ball valves play a crucial role in fluid control. In many industrial fields such as petroleum, chemical industry, and natural gas, ball valves are widely used as key components for controlling fluid on-off and flow rate. Due to the complex and diverse actual working conditions, during the long-term use of ball valves, parts such as the ball and the valve seat will be worn to varying degrees, thereby affecting their sealing performance and service life. Therefore, accurately detecting the abrasion resistance of ball valves is crucial for ensuring the stable operation of industrial systems, reducing maintenance costs, and guaranteeing production safety.

[0003] With the continuous improvement of the performance requirements for ball valves in various industries, accurately and comprehensively detecting the abrasion resistance of ball valves has become increasingly important. However, the existing ball valve abrasion resistance detection technologies and related devices have many limitations.

[0004] Most traditional ball valve abrasion resistance detection methods are relatively single, often only focusing on a specific aspect to evaluate the abrasion resistance of ball valves. Some detection devices simply use a simple mechanical structure to make the ball valve perform a relatively static friction test with a single friction medium under a fixed pressure. This method can only obtain the abrasion resistance data of the ball valve under a single friction condition and cannot simulate the various friction situations faced by the ball valve in actual complex working conditions.

[0008] Preferably, the output end of the first motor is fixedly provided with a bidirectional lead screw, one end of the bidirectional lead screw is provided with a third fixing plate, and the bottom end of the third fixing plate is fixedly arranged at the other end of the sliding groove.

[0009] Preferably, the thread directions of the bidirectional lead screw are opposite, both ends of the middle part of the bidirectional lead screw are threadedly connected to the middle part of the slider, the outer wall of the slider is slidably connected in the sliding groove of the workbench, and a wear-resistant assembly is arranged on the upper surface of the workbench.

[0010] Preferably, the wear-resistant assembly includes a bracket, the bottom end of the bracket is fixedly arranged on the upper surface of the workbench, an electric push rod is fixedly arranged on the inner top wall of the bracket, a friction plate is arranged at the output end of the electric push rod, and an auxiliary assembly is arranged on one side of the upper surface of the bracket.

[0011] Preferably, the auxiliary assembly includes a blower, the bottom end of the blower is arranged on one side of the upper surface of the bracket, and an air duct is arranged at the output end of the blower.

[0012] Preferably, one end of the air duct penetrates through the side wall of the bracket and is provided with a fog-shaped air nozzle, a connecting pipe is arranged at the bottom end of the outer wall of the air duct, a valve is arranged on the outer wall of the connecting pipe, and a water tank is arranged at the bottom end of the connecting pipe.

[0013] Preferably, the bottom end of the water tank is arranged on one side of the upper surface of the workbench, a placing plate is arranged in the middle of the upper surface of the workbench, a groove is arranged in the middle of the placing plate, a ball valve body is arranged in the groove of the placing plate, a plurality of legs are fixedly arranged on the lower surface of the workbench, and a moving mechanism is arranged at the bottom end of the legs.

[0014] Preferably, the moving mechanism includes a second fixing plate, the upper surface of the second fixing plate is fixedly arranged at the bottom end of the leg, a wheel body is arranged at the bottom end of the second fixing plate, a wheel is arranged at the bottom end of the wheel body, a wheel brake is arranged on one side of the wheel body, and a plurality of anti-slip strips are arranged on the upper surface of the wheel brake.

[0015] A usage method of a ball valve wear resistance detection device, for the ball valve wear resistance detection device described in the claims, includes the following steps:

[0016] S1. Device placement: Move the detection device to a suitable detection site, operate the wheel brake to brake the wheels, and fix the device;

[0017] S2. Install the ball valve. According to the specifications of the ball valve body, start Motor 1 to adjust the position of the clamping block, place the ball valve in the groove of the placement plate and clamp it.

[0018] S3. Parameter setting. According to the detection requirements, adjust the electric push rod to determine the friction pressure, set the rotation speed of Motor 2 to control the rotation speed of the ball valve, and operate the valve and the blower to simulate the corresponding environmental parameters.

[0019] S4. Detection and analysis. Start the relevant components to carry out the detection. After completion, turn off the power supply, analyze and record the data to evaluate the wear resistance of the ball valve.

[0020] Working principle: Move the device to a suitable detection site through the moving mechanism, and operate the wheel brake to brake the wheels to achieve fixation, ensuring the stability of subsequent detections.

[0021] When installing the ball valve, the drive assembly plays a key role. Motor 1 drives the bidirectional lead screw to rotate. Due to the threaded connection between the lead screw and the slider and the sliding fit of the slider in the chute, the slider drives the clamping block to move, and the distance between the clamping blocks can be adjusted according to the specifications of the ball valve body, and the ball valve is placed in the groove of the placement plate and clamped.

[0022] Next is the parameter setting link. In the wear-resistant assembly, the electric push rod expands and contracts to change the distance between the friction plate and the ball valve to determine the friction pressure; Motor 2 drives a series of transmission components to make the steering wheel in contact with the ball valve rotate, controlling the rotation speed of the ball valve. At the same time, in the auxiliary assembly, the operation valve and the blower cooperate. According to Bernoulli's principle, the air flow of the blower generates a pressure difference, causing the water in the water tank to be sucked out through the connecting pipe, mixed with the air flow and sprayed out from the atomizing air nozzle, simulating different environmental conditions.

[0023] Finally, enter the detection and analysis stage. Start each relevant component, and under the set friction pressure, ball valve rotation speed, and simulated environment, make the ball valve be in a working state simulating the actual working conditions. During the detection process, use the corresponding sensors to collect wear data. After completion, turn off the power supply, systematically analyze the collected data, and comprehensively evaluate the wear resistance of the ball valve. Overall, each component cooperates closely, from installation, parameter setting to detection and analysis, accurately simulating the operation and wear of the ball valve under different working conditions, thereby realizing the effective detection of the wear resistance of the ball valve.

[0024] The present invention provides a device for detecting the wear resistance of a ball valve and its use method. It has the following beneficial effects:

[0025] 1. Through the adjustment of the position of the ball valve body by the drive assembly and the multi-angle rotation of the ball valve body driven by Motor 2, the present invention can make all surfaces and angles of the ball valve body come into full contact with the friction test components. This means that the friction test can be carried out on the ball valve body at different angles and positions, comprehensively simulating various friction situations that the ball valve body may encounter during actual use, and obtaining more comprehensive and accurate wear data.

[0026] 2. The present invention controls the position of the slider by driving the bidirectional lead screw with the first motor, enabling precise positioning of the ball valve body in the horizontal direction. Regardless of how the size of the ball valve body changes, the distance between the two clamping blocks can be flexibly adjusted to firmly clamp ball valve bodies of different specifications, ensuring that the ball valve body does not experience displacement or other situations during subsequent detection.

[0027] 3. The present invention precisely controls the position of the friction plate and the contact pressure between the friction plate and the ball valve body through the electric push rod, enabling simulation of friction conditions under different pressure levels. Whether it is the relatively light friction that a ball valve experiences in a low-pressure and small-flow pipeline or the high-intensity friction it faces under harsh working conditions such as high pressure and large flow, relatively precise simulation can be achieved by adjusting the parameters of the electric push rod.

[0028] 4. The present invention enables simulation of various different environmental working conditions by the blower working in cooperation with the water tank based on Bernoulli's principle. It can create only a simple air flow environment to simulate the use of the ball valve in a well-ventilated and dry industrial pipeline; or it can create a complex environment such as humidity and dust to simulate the various external factor influences that the ball valve faces under harsh working conditions, making the detection environment closer to the real environment of the ball valve in actual complex application scenarios and greatly enriching the types of simulated working conditions.

[0039] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Please refer to the attached Figure 1 - attached Figure 6 , an embodiment of the present invention provides a ball valve wear resistance detection device, including a workbench 1. A chute 18 is provided in the middle of the upper surface of the workbench 1. A driving assembly is provided in the chute 18 of the workbench 1. Both ends of the middle of the driving assembly are threadedly connected with slide blocks 24. The top of the slide block 24 is fixedly provided with a clamping block 13. A cavity is provided inside the clamping block 13. A second motor 28 is provided inside the clamping block 13. The output end of the second motor 28 is fixedly provided with a first bevel gear 21. The tooth end of the first bevel gear 21 is meshed and connected with a second bevel gear 22. The outer wall of the second bevel gear 22 is fixedly provided with a double-groove pulley 23. The bottom end of the second bevel gear 22 is rotatably connected to one side of the driving assembly. A transmission belt 27 is connected to the middle of the double-groove pulley 23. One end of the transmission belt 27 is connected with a pulley 26. A rotating shaft 25 is fixedly provided in the middle of the pulley 26. A plurality of steering wheels 16 are provided on the outer wall of the rotating shaft 25. The rotating shaft 25 and the steering wheels 16 are provided inside the clamping block 13.

[0041] Specifically, the drive assembly provided in the chute 18 of the workbench 1 mainly drives the slider 24 to move through its internal transmission structure. The specific transmission components of the drive assembly are threadedly connected to the middle part of the slider 24. When the drive assembly starts to operate, this threaded transmission relationship enables the slider 24 to move in a straight line along a specific trajectory within the chute 18. Since the clamping block 13 is fixedly arranged at the top of the slider 24, the movement of the slider 24 directly drives the clamping block 13 to move. This process can accurately adjust the position of the clamping block 13 according to actual needs, so as to adapt to the installation requirements of ball valves of different specifications, ensure that the ball valve can be accurately fixed at the detection position, and create a basic condition for position adjustment for subsequent multi-angle friction tests. In the internal cavity of the clamping block 13, the motor two 28 is the power source for driving the ball valve body 14 to rotate. After the motor two 28 is started, the bevel gear one 21 at its output end starts to rotate. Because the bevel gear one 21 meshes with the bevel gear two 22, according to the characteristics of gear transmission, the rotation of the bevel gear one 21 will drive the bevel gear two 22 to rotate. And the double-groove pulley 23 fixed to the outer wall of the bevel gear two 22 will rotate synchronously with the bevel gear two 22. The double-groove pulley 23 is connected to the pulley 26 through the transmission belt 27. The rotation of the double-groove pulley 23 is transmitted to the pulley 26 through the transmission belt 27, and then drives the rotating shaft 25 fixedly connected to the middle part of the pulley 26 to rotate. Since a number of turning wheels 16 are arranged on the outer wall of the rotating shaft 25, the rotation of the rotating shaft 25 will cause the turning wheels 16 to rotate. The turning wheels 16 are in contact with the ball valve body 14 and drive the ball valve body 14 to rotate through friction. Moreover, by controlling the rotation speed, rotation direction and running time of the motor two 28, the rotation speed, direction and angle of the ball valve body 14 can be accurately controlled, realizing the rotation of the ball valve body 14 at different angles, so as to cooperate with the friction test component to conduct multi-angle friction tests on the ball valve body 14.

[0042] By adjusting the position of the ball valve body 14 through the drive assembly and driving the multi-angle rotation of the ball valve body 14 by the motor two 28, all surfaces and angles of the ball valve body 14 can be brought into full contact with the friction test component. This means that friction tests can be carried out on the ball valve body 14 at different angles and positions, comprehensively simulating various friction situations that the ball valve body 14 may encounter during actual use, and obtaining more comprehensive and accurate wear data.

[0043] Please refer to the appendix Figure 1 - appendix Figure 6, the driving component includes a first fixed plate 15. The bottom end of the first fixed plate 15 is fixedly arranged at one end of the sliding groove 18 of the workbench 1. The top of the first fixed plate 15 is rotatably connected to the bottom end of the second bevel gear 22. A first motor 17 is arranged in the middle of the first fixed plate 15. The output end of the first motor 17 is fixedly provided with a bidirectional lead screw 19. One end of the bidirectional lead screw 19 is provided with a third fixed plate 33. The bottom end of the third fixed plate 33 is fixedly arranged at the other end of the sliding groove 18. The thread directions of the bidirectional lead screw 19 are opposite. The two ends in the middle of the bidirectional lead screw 19 are threadedly connected to the middle of the slider 24. The outer wall of the slider 24 is slidably connected in the sliding groove 18 of the workbench 1. A wear-resistant component is arranged on the upper surface of the workbench 1.

[0044] Specifically, the key parts of the driving component are the first motor 17, the bidirectional lead screw 19, and the first fixed plate 15 and the third fixed plate 33 that cooperate with them. The bottom end of the first fixed plate 15 is fixed at one end of the sliding groove 18 of the workbench 1, providing support and positioning for one end of the entire driving component. The bottom end of the third fixed plate 33 is fixedly arranged at the other end of the sliding groove 18. In this way, the bidirectional lead screw 19 is erected in the space defined by the sliding groove 18. One end of it is fixedly connected to the output end of the first motor 17, and the first motor 17 is installed in the middle of the first fixed plate 15. When the first motor 17 is started, according to the principle that the rotation of the motor drives the rotation of the lead screw, the power output by the first motor 17 will cause the bidirectional lead screw 19 to start rotating. Since the thread directions of the bidirectional lead screw 19 are opposite, and the two ends in the middle of it are threadedly connected to the middle of the slider 24, and the outer wall of the slider 24 is slidably connected in the sliding groove 18 of the workbench 1, when the bidirectional lead screw 19 rotates, based on the characteristics of lead screw transmission, the two sliders 24 will perform linear sliding motions in opposite or the same directions along the sliding groove 18. This motion mode can accurately control the position of the slider 24, and then drive the clamp 13 fixed at the top of the slider 24 to adjust its position, and finally change the position of the ball valve body 14 placed between the clamps 13 so that it can be in a suitable initial detection position. The top of the first fixed plate 15 is also rotatably connected to the bottom end of the second bevel gear 22. This connection relationship enables the second bevel gear 22 to have a stable support point in the transmission system of the entire device and can operate smoothly relying on the first fixed plate 15 when it rotates itself. In the subsequent transmission, the second bevel gear 22 cooperates with components such as the first bevel gear 21 inside the clamp 13 to further transmit the power and drive the ball valve body 14 to rotate, preparing for multi-angle wear resistance detection. Moreover, the wear-resistant component arranged on the upper surface of the workbench 1 can interact with the ball valve body 14 whose position is adjusted by the driving component to jointly complete the detection work of the wear resistance of the ball valve body 14.

[0045] The position of the slider 24 is controlled by driving the bidirectional lead screw 19 through the first motor 17, enabling precise positioning of the ball valve body 14 in the horizontal direction. Regardless of how the size of the ball valve body 14 changes, the distance between the two clamping blocks 13 can be flexibly adjusted so that it can firmly clamp ball valve bodies 14 of different specifications, ensuring that the ball valve body 14 will not be displaced during subsequent detection processes, and ensuring the stable development of the detection work.

[0046] Please refer to the attached Figure 1 - attached Figure 2 , the wear-resistant component includes a bracket 4, the bottom end of the bracket 4 is fixedly arranged on the upper surface of the workbench 1, an electric push rod 5 is fixedly arranged on the inner top wall of the bracket 4, a friction plate 6 is arranged at the output end of the electric push rod 5, and an auxiliary component is arranged on one side of the upper surface of the bracket 4.

[0047] Specifically, the core part of the wear-resistant component is the electric push rod 5 and the friction plate 6 connected thereto, and the entire component is installed and positioned relying on the bracket 4 fixed on the upper surface of the workbench 1. The bottom end of the bracket 4 is firmly fixed on the upper surface of the workbench 1, providing a stable support structure for the components above. An electric push rod 5 is fixedly arranged on the inner top wall of the bracket 4. The electric push rod 5 is a device that can convert electrical energy into linear motion mechanical energy. When the electric push rod 5 is powered on and started, according to the principle that the motor inside the electric push rod 5 drives the lead screw transmission to push the push rod to perform linear telescopic motion, the output end of the electric push rod 5 will perform telescopic motion along the set direction. And the friction plate 6 is installed at the output end of the electric push rod 5, so as the output end of the electric push rod 5 telescopes, the friction plate 6 will also correspondingly perform linear motion in the up and down direction. By adjusting the telescopic length of the electric push rod 5, the distance and the contact pressure between the friction plate 6 and the ball valve body 14 placed below can be precisely controlled, thereby simulating different degrees of friction acting on the ball valve body 14.

[0048] Precisely controlling the position of the friction plate 6 and the contact pressure between the friction plate 6 and the ball valve body 14 through the electric push rod 5 can simulate the friction conditions under different pressure levels. Whether it is the relatively light friction that the ball valve experiences in low-pressure and small-flow pipelines, or the high-intensity friction it faces under harsh working conditions such as high pressure and large flow, it can be more precisely simulated by adjusting the parameters of the electric push rod 5, so as to obtain the wear-resistant performance data of the ball valve body 14 under different friction degrees, providing a basis more in line with the actual use situation for evaluating its quality.

[0049] Please refer to the attached Figure 1 - attached Figure 2 、attached Figure 7, The auxiliary component includes a blower 7. The bottom end of the blower 7 is arranged on one side of the upper surface of the bracket 4. The output end of the blower 7 is provided with an air duct 8. One end of the air duct 8 penetrates through the side wall of the bracket 4 and is provided with a foggy air nozzle 9. The bottom end of the outer wall of the air duct 8 is provided with a connecting pipe 11. A valve 10 is arranged on the outer wall of the connecting pipe 11. The bottom end of the connecting pipe 11 is provided with a water tank 12. The bottom end of the water tank 12 is arranged on one side of the upper surface of the workbench 1. In the middle of the upper surface of the workbench 1, there is a placement tray 20. A groove is arranged in the middle of the placement tray 20. A spherical valve body 14 is arranged in the groove of the placement tray 20. A plurality of legs 2 are fixedly arranged on the lower surface of the workbench 1. The bottom ends of the legs 2 are provided with moving mechanisms.

[0050] Specifically, the blower 7 in the auxiliary component serves as the core power source, and its bottom end is stably arranged on one side of the upper surface of the bracket 4. After the blower 7 is powered on and started, the motor drives the impeller to rotate at a high speed. According to the principle of aerodynamics, air will be quickly sucked into the interior of the blower 7 and then discharged from its output end at a relatively high flow rate. The discharged air is conveyed along the air duct 8. Since one end of the air duct 8 penetrates through the side wall of the bracket 4 and is provided with a foggy air nozzle 9, the air will finally be sprayed around the spherical valve body 14 placed in the groove of the placement tray 20 through the foggy air nozzle 9 in a specific form and speed, creating an air flow environment with different intensities and directions, simulating working conditions such as air flow scouring in ventilation ducts that the ball valve may encounter during actual use. At the same time, according to Bernoulli's principle, when the blower 7 generates a large air flow, the air flow speed increases, and the pressure at its location will decrease, thus forming a relatively low-pressure area at the connection between the air duct 8 and the connecting pipe 11. The water in the water tank 12 is in an atmospheric pressure state. Under the action of the pressure difference, the water in the water tank 12 will be sucked by the suction force from the direction of the connecting pipe 11, prompting the water to flow from the water tank 12 through the connecting pipe 11 into the air duct 8. After the water flows into the air duct 8, the high-speed air flow continuously blown by the blower 7 will carry the water forward together, causing the water to be dispersed into tiny water droplets. These air flows carrying foggy water droplets are sprayed out from the foggy air nozzle 9 together, and then sprayed around the spherical valve body 14 to create a complex simulated environment such as humidity and dust.

[0051] By the blower 7 working in cooperation with the water tank 12 according to Bernoulli's principle, it is possible to simulate a variety of different environmental working conditions. It can create only a simple air flow environment to simulate the use of the ball valve in a well-ventilated and dry industrial pipeline; it can also create a complex environment such as humidity and dust to simulate the various external factor influences faced by the ball valve under harsh working conditions, making the detection environment closer to the real environment of the ball valve in actual complex application scenarios, greatly enriching the types of simulated working conditions.

[0052] Please refer to the appendix Figure 1 - appendix Figure 2 、appendix Figure 8, The moving mechanism includes a second fixing plate 29. The upper surface of the second fixing plate 29 is fixedly arranged at the bottom end of the support leg 2. A wheel body 30 is arranged at the bottom end of the second fixing plate 29. A wheel 3 is arranged at the bottom end of the wheel body 30. A wheel brake 32 is arranged on one side of the wheel body 30. A plurality of anti-slip strips 31 are arranged on the upper surface of the wheel brake 32.

[0053] Specifically, the key part of the moving mechanism is the wheel body 30 and the wheel 3 at its bottom end. The entire structure is installed and connected relying on the second fixing plate 29. The upper surface of the second fixing plate 29 is firmly fixed at the bottom end of the support leg 2, providing stable support for the wheel body 30 and the wheel 3 below. When the entire ball valve wear resistance detection device needs to be moved, the operator applies an external force to the device. According to the principle of rolling friction between the wheel 3 and the ground, the wheel 3 will roll on the ground, thereby driving the entire device to move. Compared with the traditional method of relying on manual handling, this method of moving through the rolling of the wheel 3 greatly reduces the friction force, enabling the device to easily move its position on a relatively flat ground, facilitating the movement of the device from the storage location to the detection site, or flexibly deploying it between different detection areas, workshops, and other places.

[0054] Through the setting of the wheel 3, the entire ball valve wear resistance detection device has good mobility. Whether it is moving between different areas inside the laboratory or being transferred between different places such as factory workshops and warehouses, the operator can relatively easily push the device to the designated location without consuming a large amount of manpower and time for handling, greatly improving the mobility and usage efficiency of the device and facilitating the flexible arrangement of the detection position according to the actual detection requirements.

[0055] Please refer to the appendix Figure 1 - appendix Figure 8 , A method for using a ball valve wear resistance detection device, for the ball valve wear resistance detection device described in the claims, includes the following steps:

[0056] S1. Device placement: Move the detection device to a suitable detection site, operate the wheel brake 32 to brake the wheel 3, and fix the device;

[0057] S2. Install the ball valve: According to the specifications of the ball valve body 14, start the first motor 17 to adjust the position of the clamping block 13, place the ball valve in the groove of the placement plate 20 and clamp it;

[0058] S3. Parameter setting: According to the detection requirements, adjust the electric push rod 5 to determine the friction pressure, set the rotation speed of the second motor 28 to control the rotation speed of the ball valve, and operate the valve 10 and the blower 7 to simulate the corresponding environmental parameters;

[0059] S4. Detection and analysis: Start the relevant components to carry out the detection. After completion, turn off the power supply, analyze and record the data to evaluate the wear resistance of the ball valve.

[0060] Specifically, through the rolling contact of the wheels 3 in the moving mechanism with the ground, the entire ball valve wear resistance detection device is pushed by an external force, enabling it to move on the ground, thereby transferring the device to a suitable detection site. When the predetermined position is reached, the wheel brake 32 is operated, and the braking components inside the wheel brake 32 will come into close contact with the wheel body 30. According to the principle of friction, the rotation of the wheels 3 is stopped by increasing the friction force. Moreover, the anti-slip strips 31 provided on the upper surface of the wheel brake 32 further enhance this friction effect, enabling the device to be firmly fixed at the detection site and preventing accidental movement due to external factors (such as slight vibrations caused by people walking and minor inclinations of the ground).

[0061] According to the specifications and dimensions of the ball valve body 14, the motor one 17 in the drive assembly is started, and the motor one 17 drives the bidirectional lead screw 19 to rotate. Since the thread directions of the bidirectional lead screw 19 are opposite and it is threadedly connected to the middle of the slider 24, and the slider 24 is also slidably connected in the chute 18 of the workbench 1, the rotation of the bidirectional lead screw 19 will cause the two sliders 24 to perform linear sliding motions in opposite or the same directions along the chute 18, thereby driving the clamping blocks 13 fixed at the top of the sliders 24 to adjust their positions. When the distance between the clamping blocks 13 is adjusted to an appropriate size, the ball valve is placed in the groove with high smoothness in the middle of the placement plate 20 that allows the ball valve body 14 to rotate in place. Subsequently, the clamping blocks 13 clamp the ball valve to ensure that the ball valve will not loosen or shift during subsequent detection and can be stably in the detection position.

[0062] In terms of the wear-resistant component, by adjusting the telescopic length of the electric push rod 5, according to the linear motion principle of the electric push rod 5, the distance between the friction plate 6 connected to its output end and the ball valve is changed, thereby determining the magnitude of the contact pressure between the two, so as to simulate the friction conditions faced by the ball valve under different pressure levels during actual use.

[0063] For the part that drives the rotation of the ball valve, by setting the rotation speed of the motor two 28, the rotation of the motor two 28 is transmitted through the meshing of the bevel gear one 21 and the bevel gear two 22 to drive the double-groove pulley 23 to rotate, and then transmitted to the pulley 26 through the transmission belt 27, thereby causing the rotation shaft 25 and the steering wheel 16 on its outer wall to rotate, and finally driving the ball valve to rotate at a set speed to simulate the actual rotation state of the ball valve under different working conditions.

[0064] In the auxiliary component, operating the valve 10 can control the connection between the water tank 12 and the air duct 8. In combination with the operation of the blower 7, according to Bernoulli's principle, when the blower 7 generates a large airflow, the pressure difference generated by the airflow will suck the water in the water tank 12 out through the connecting pipe 11 and mix it with the airflow, and then spray it out from the atomizing nozzle 9. By adjusting parameters such as the opening and closing degree of the valve 10 and the air volume of the blower 7, different environmental working conditions such as dry airflow and humid and dusty air can be simulated, and the working conditions of the ball valve in the actual complex environment can be simulated.

[0065] Start relevant components such as the first motor 17, the second motor 28, the electric push rod 5, and the blower 7, and each component works together according to the previously set parameters. The second motor 28 drives the ball valve to rotate, and the electric push rod 5 applies a set friction pressure to the rotating ball valve by the friction plate 6. At the same time, the blower 7 creates corresponding environmental conditions acting on the ball valve to simulate the working state and wear environment of the ball valve under actual working conditions. During a certain period of detection, collect the wear-related data of each part of the ball valve under this simulated working condition. After the detection is completed, turn off the power supply and stop the operation of each component. Then, use professional data processing and analysis methods to sort out and analyze the recorded data. For example, by comparing the change in wear amount in different time periods and the difference in wear degree under different working conditions, etc., comprehensively evaluate the wear resistance of the ball valve.

The scope of the present invention is defined by the appended claims and their equivalents.
