Description

Technical Field

[0001] The invention relates to the technical field of ball valve detection, and in particular to a ball valve wear resistance detection device and a use method thereof. Background Art

[0002] In the industrial field and many pipeline systems, ball valves play a vital role in fluid control. In many industrial fields such as petroleum, chemical industry, and natural gas, ball valves are widely used as key components to control fluid on / off and flow. Due to the complexity and diversity of actual working conditions, the ball valve and valve seat will be worn to varying degrees during long-term use, which will affect its sealing performance and service life. Therefore, accurate detection of the wear resistance of ball valves is crucial to ensure the stable operation of industrial systems, reduce maintenance costs, and ensure production safety.

[0003] As the performance requirements of ball valves in various industries continue to increase, it is increasingly important to accurately and comprehensively detect the wear resistance of ball valves. However, the existing ball valve wear resistance detection technology and related devices have many limitations.

[0004] Traditional ball valve wear resistance testing methods are mostly relatively simple, often focusing on a specific aspect to evaluate the wear resistance of ball valves. Some testing devices only use simple mechanical structures to conduct relatively static friction tests on ball valves with a single friction medium under fixed pressure. This method can only obtain the wear resistance data of ball valves under single friction conditions, and cannot simulate the various friction conditions that ball valves face under actual complex working conditions.

[0008] Preferably, a bidirectional screw is fixedly provided at the output end of the motor one, a fixing plate three is provided at one end of the bidirectional screw, and a bottom end of the fixing plate three is fixedly provided at the other end of the slide groove.

[0009] Preferably, the thread directions of the bidirectional screw are opposite, the two ends of the middle part of the bidirectional screw are threadedly connected to the middle part of the slider, the outer wall of the slider is slidably connected in the slide groove of the workbench, and the upper surface of the workbench is provided with a wear-resistant component.

[0010] Preferably, the wear-resistant component 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 component is arranged on one side of the upper surface of the bracket.

[0011] Preferably, the auxiliary component comprises a blower, the bottom end of the blower is arranged on one side of the upper surface of the bracket, and the output end of the blower is provided with an air duct.

[0012] Preferably, one end of the air duct is provided with a mist nozzle penetrating through the side wall of the bracket, a connecting pipe is provided at the bottom end of the outer wall of the air duct, a valve is provided on the outer wall of the connecting pipe, and a water tank is provided 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 fixed plate, the upper surface of which is fixedly arranged at the bottom end of the support leg, a wheel body is arranged at the bottom end of the second fixed plate, a wheel is arranged at the bottom end of the wheel body, a wheel is arranged at 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 method for using a ball valve wear resistance detection device, used for a ball valve wear resistance detection device as described in the claims, comprising the following steps: S1. Device placement: move the test device to a suitable test site, operate the wheel brake to brake the wheel, and fix the device; S2. Install the ball valve. According to the specifications of the ball valve body, start the motor to adjust the position of the clamping block, place the ball valve in the groove of the placement plate and clamp it; S3, parameter setting, according to the test requirements, adjust the electric push rod to determine the friction pressure, set the second motor speed to control the ball valve rotation speed, operate the valve and blower to simulate the corresponding environmental parameters; S4, detection and analysis, start the relevant components to carry out detection, turn off the power after completion, analyze and record the data to evaluate the wear resistance of the ball valve.

[0016] Working principle: Move the device to a suitable testing site through a mobile mechanism, operate the wheel brake to fix the wheel, and ensure stability for subsequent testing.

[0017] When installing a ball valve, the drive assembly plays a key role. The motor drives the bidirectional screw to rotate. Due to the threaded connection between the screw and the slider and the sliding fit of the slider in the slide groove, the slider drives the clamping block to move. 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 placement plate groove and clamped.

[0018] Next comes the parameter setting phase. In the wear-resistant component, the electric push rod is extended and retracted to change the distance between the friction plate and the ball valve to determine the friction pressure; the second motor drives a series of transmission components to rotate the steering wheel in contact with the ball valve to control the rotation speed of the ball valve. At the same time, in the auxiliary component, the operating valve cooperates with the blower. According to the Bernoulli principle, the blower airflow generates a pressure difference to suck the water in the water tank out through the connecting pipe, mix with the airflow and spray out from the mist nozzle, simulating different environmental conditions.

[0019] Finally, we enter the detection and analysis phase, start all relevant components, and put the ball valve into a working state that simulates the actual working conditions under the set friction pressure, ball valve rotation speed and simulation environment. During the detection process, the corresponding sensors are used to collect wear data. After the end, the power is turned off, and the collected data is systematically analyzed to comprehensively evaluate the wear resistance of the ball valve. Overall, the various components work closely together, from installation, parameter setting to detection and analysis, to accurately simulate the operation and wear of the ball valve under different working conditions, thereby achieving effective detection of the wear resistance of the ball valve.

[0020] The present invention provides a ball valve wear resistance detection device and a method for using the same. The device has the following beneficial effects: 1. The present invention can make all surfaces and angles of the ball valve body fully contact with the friction test component by adjusting the position of the ball valve body through the drive assembly and driving the ball valve body to rotate at multiple angles through the motor 2. This means that the ball valve body can be subjected to friction tests at different angles and positions, fully simulating various friction conditions that the ball valve body may encounter during actual use, and obtaining more comprehensive and accurate wear data.

[0021] 2. The present invention controls the position of the slider by driving the bidirectional screw rod to rotate through the motor, and can realize accurate positioning of the ball valve body in the horizontal direction. No matter how the size of the ball valve body changes, the distance between the two clamping blocks can be flexibly adjusted, so that the ball valve bodies of different specifications can be firmly clamped, ensuring that the ball valve body will not be displaced during the subsequent detection process.

[0022] 3. The present invention can simulate the friction conditions under different pressure levels by accurately controlling the position of the friction plate and the contact pressure between the friction plate and the ball valve body through the electric push rod. Whether it is the relatively light friction of the ball valve in a low-pressure, small-flow pipeline, or the high-intensity friction faced under harsh working conditions such as high pressure and large flow, a relatively accurate simulation can be achieved by adjusting the parameters of the electric push rod.

[0023] 4. The present invention can simulate a variety of different environmental conditions by using the blower to work in conjunction with the water tank based on the Bernoulli principle. It can create a simple airflow environment to simulate the use of ball valves in well-ventilated and dry industrial pipelines; it can also create a humid, dusty and other complex environment to simulate the various external factors that ball valves face 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.

DETAILED DESCRIPTION

[0026] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Please refer to the attached Figure 1 -Attached Figure 6 The embodiment of the present invention provides a ball valve wear resistance detection device, including a workbench 1, a slide groove 18 is arranged in the middle of the upper surface of the workbench 1, a driving assembly is arranged in the slide groove 18 of the workbench 1, sliders 24 are threadedly connected at both ends of the middle of the driving assembly, a clamping block 13 is fixedly arranged on the top of the slider 24, a cavity is arranged inside the clamping block 13, a motor 28 is arranged inside the clamping block 13, a bevel gear 1 21 is fixedly arranged on the output end of the motor 28, a bevel gear 22 is meshedly connected with the tooth end of the bevel gear 1 21, a double-groove pulley 23 is fixedly arranged on the outer wall of the bevel gear 22, the bottom end of the 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, a pulley 26 is connected to one end of the transmission belt 27, a rotating shaft 25 is fixedly arranged in the middle of the pulley 26, a plurality of steering wheels 16 are arranged on the outer wall of the rotating shaft 25, and the rotating shaft 25 and the steering wheel 16 are arranged inside the clamping block 13.

[0028] Specifically, the driving assembly arranged in the chute 18 of the workbench 1 mainly drives the slider 24 to move through its internal transmission structure. The specific transmission component of the driving assembly is threadedly connected to the middle of the slider 24. When the driving assembly starts to operate, this threaded transmission relationship enables the slider 24 to move linearly along a specific trajectory in the chute 18. Since the top of the slider 24 is fixedly provided with a clamping block 13, 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 the basic conditions for position adjustment for subsequent multi-angle friction tests. In the internal cavity of the clamping block 13, the motor 28 is the power source for driving the ball valve body 14 to rotate. After the motor 28 is started, the bevel gear 1 21 at its output end starts to rotate. Because the bevel gear 1 21 and the bevel gear 2 22 are meshed with each other, according to the characteristics of the gear transmission, the rotation of the bevel gear 1 21 will drive the bevel gear 2 22 to rotate. The double-groove pulley 23 fixed on the outer wall of the bevel gear 22 will rotate synchronously with the bevel gear 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, thereby driving the rotating shaft 25 fixedly connected to the middle part of the pulley 26 to rotate. Since a plurality of steering wheels 16 are arranged on the outer wall of the rotating shaft 25, the rotation of the rotating shaft 25 will cause the steering wheels 16 to rotate. The steering 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 speed, direction and running time of the motor 28, the rotation speed, direction and angle of the ball valve body 14 can be accurately controlled to realize the rotation of the ball valve body 14 at different angles, thereby cooperating with the friction test component to perform multi-angle friction tests on the ball valve body 14.

[0029] By adjusting the position of the ball valve body 14 by the driving assembly and driving the motor 28 to rotate the ball valve body 14 at multiple angles, each surface and angle of the ball valve body 14 can be fully in contact with the friction test component. This means that the ball valve body 14 can be subjected to friction tests at different angles and positions, fully simulating various friction conditions that the ball valve body 14 may encounter during actual use, and obtaining more comprehensive and accurate wear data.

[0030] Please refer to the attached Figure 1 -Attached Figure 6The driving assembly includes a fixed plate 15, the bottom end of the fixed plate 15 is fixedly arranged at one end of the slide groove 18 of the workbench 1, the top of the fixed plate 15 is rotatably connected to the bottom end of the bevel gear 22, a motor 17 is arranged in the middle of the fixed plate 15, a bidirectional screw 19 is fixedly arranged at the output end of the motor 17, a fixed plate 3 33 is arranged at one end of the bidirectional screw 19, the bottom end of the fixed plate 3 33 is fixedly arranged at the other end of the slide groove 18, the thread directions of the bidirectional screw 19 are opposite, the two ends of the middle part of the bidirectional screw 19 are threadedly connected to the middle part of the slider 24, the outer wall of the slider 24 is slidably connected in the slide groove 18 of the workbench 1, and a wear-resistant assembly is arranged on the upper surface of the workbench 1.

[0031] Specifically, the key parts of the drive assembly are the motor 17, the bidirectional screw 19, and the structures such as the fixed plate 15 and the fixed plate 3 33 that cooperate therewith. The bottom end of the fixed plate 15 is fixed to one end of the slide slot 18 of the workbench 1, providing support and positioning for one end of the entire drive assembly. The bottom end of the fixed plate 3 33 is fixedly set at the other end of the slide slot 18, so that the bidirectional screw 19 is erected in the space defined by the slide slot 18, and one end of the bidirectional screw 19 is fixedly connected to the output end of the motor 17, and the motor 17 is installed in the middle position of the fixed plate 15. When the motor 17 is started, according to the principle that the rotation of the motor drives the rotation of the screw, the power output by the motor 17 will cause the bidirectional screw 19 to start rotating. Since the thread directions of the bidirectional screw 19 are opposite, and the two ends of the middle are threadedly connected to the middle of the slider 24, and the outer wall of the slider 24 is slidably connected in the slide groove 18 of the workbench 1, when the bidirectional screw 19 rotates, based on the characteristics of the screw transmission, the two sliders 24 will make linear sliding movements in opposite directions along the slide groove 18. This movement mode can accurately control the position of the slider 24, thereby driving the clamping block 13 fixed on the top of the slider 24 to adjust the position, and finally realize the change of the position of the ball valve body 14 placed between the clamping blocks 13, so that it can be in a suitable initial position for detection. The top of the fixed plate 15 is also rotatably connected to the bottom end of the bevel gear 22. This connection relationship allows the bevel gear 22 to have a stable support point in the transmission system of the entire device, and it can operate smoothly with the fixed plate 15 as support when it rotates. In the subsequent transmission, the bevel gear 22 cooperates with the bevel gear 1 21 and other components inside the clamping block 13 to further transmit the power, drive the ball valve body 14 to rotate, and prepare for multi-angle wear resistance testing. In addition, the wear-resistant component set on the upper surface of the workbench 1 can interact with the ball valve body 14 adjusted in position by the driving component to jointly complete the wear resistance testing of the ball valve body 14.

[0032] The position of the slider 24 is controlled by driving the bidirectional screw rod 19 to rotate by the motor 17, so that the ball valve body 14 can be accurately positioned in the horizontal direction. No matter how the size of the ball valve body 14 changes, the distance between the two clamping blocks 13 can be flexibly adjusted so that the ball valve body 14 of different specifications can be firmly clamped, ensuring that the ball valve body 14 will not be displaced during the subsequent detection process, and ensuring that the detection work can be carried out stably.

[0033] 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.

[0034] Specifically, the core part of the wear-resistant assembly is the electric push rod 5 and the friction plate 6 connected thereto. The entire assembly is installed and positioned by 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 upper components. The 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 mechanical energy of linear motion. When the electric push rod 5 is powered on and started, according to the principle that the internal motor of the electric push rod 5 drives the 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. The friction plate 6 is installed on the output end of the electric push rod 5, so as the output end of the electric push rod 5 is extended and retracted, the friction plate 6 will also perform linear motion in the up and down directions accordingly. By adjusting the telescopic length of the electric push rod 5, the distance between the friction plate 6 and the ball valve body 14 placed below and the size of the contact pressure can be accurately controlled, thereby simulating different degrees of friction applied to the ball valve body 14.

[0035] The electric push rod 5 can accurately control the position of the friction plate 6 and the contact pressure between the friction plate 6 and the ball valve body 14, so as to simulate the friction conditions under different pressure levels. Whether it is the relatively light friction of the ball valve in a low-pressure, small-flow pipeline, or the high-intensity friction faced under harsh working conditions such as high pressure and large flow, a relatively accurate simulation can be achieved by adjusting the parameters of the electric push rod 5, thereby obtaining the wear resistance performance data of the ball valve body 14 under different friction levels, providing a basis that is more in line with actual use conditions for evaluating its quality.

[0036] Please refer to the attached Figure 1 -Attached Figure 2 , Attachment Figure 7The 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, an air duct 8 is arranged at the output end of the blower 7, one end of the air duct 8 passes through the side wall of the bracket 4 and is provided with a mist nozzle 9, a connecting pipe 11 is arranged at the bottom end of the outer wall of the air duct 8, a valve 10 is arranged on the outer wall of the connecting pipe 11, a water tank 12 is arranged at the bottom end of the connecting pipe 11, and the bottom end of the water tank 12 is arranged on one side of the upper surface of the workbench 1, a placing plate 20 is arranged in the middle of the upper surface of the workbench 1, a groove is arranged in the middle of the placing plate 20, a ball valve body 14 is arranged in the groove of the placing plate 20, and a plurality of legs 2 are fixedly arranged on the lower surface of the workbench 1, and a moving mechanism is arranged at the bottom end of the legs 2.

[0037] 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. When 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, the air will be quickly sucked into the blower 7 and then discharged from its output end at a higher flow rate. The discharged air is transported along the air duct 8. Since one end of the air duct 8 penetrates the side wall of the bracket 4 and is provided with a mist nozzle 9, the air will eventually be sprayed through the mist nozzle 9 in a specific form and speed to the ball valve body 14 placed in the groove of the placement plate 20, creating an air flow environment of different strengths and directions, simulating the working conditions that the ball valve may encounter in actual use, such as air flow scouring in the ventilation duct. At the same time, according to the Bernoulli principle, when the blower 7 generates a large air flow, the air flow speed increases, and the pressure at its location decreases, thereby 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 at normal pressure. Under the action of the pressure difference, the water in the water tank 12 will be sucked from the connecting pipe 11, causing 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 airflow continuously blown out by the blower 7 will carry the water forward together, causing the water to be blown away to form tiny water droplets. These airflows carrying mist water droplets are sprayed out from the mist nozzle 9 together, and then sprayed around the ball valve body 14 to create a complex simulated environment such as humidity and dust.

[0038] By using the blower 7 to work in conjunction with the water tank 12 based on the Bernoulli principle, it is possible to simulate a variety of different environmental conditions. It is possible to create a simple airflow environment to simulate the use of ball valves in well-ventilated and dry industrial pipelines; it is also possible to create a humid, dusty and other complex environment to simulate the various external factors 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, greatly enriching the types of simulated working conditions.

[0039] Please refer to the attached Figure 1 -Attached Figure 2 , Attachment Figure 8The moving mechanism includes a fixed plate 29, the upper surface of the fixed 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 fixed 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, and a plurality of anti-slip strips 31 are arranged on the upper surface of the wheel brake 32.

[0040] Specifically, the key parts of the mobile mechanism are the wheel body 30 and the wheel 3 at its bottom, and the entire structure relies on the fixing plate 29 for installation and connection. The upper surface of the fixing plate 29 is firmly fixed to the bottom of the 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 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 manpower to carry, this method of moving by rolling the wheel 3 greatly reduces the friction, so that the device can be easily transferred on a relatively flat ground, which is convenient for moving the device from a storage location to a detection site, or flexibly deployed between different detection areas, workshops and other places.

[0041] The arrangement of the wheels 3 enables the entire ball valve wear resistance testing device to have good mobility. Whether moving between different areas within the laboratory or transferring between different places such as factory workshops and warehouses, operators can push the device to the designated location relatively easily without spending a lot of manpower and time on transportation, which greatly improves the mobility and use efficiency of the device and facilitates the flexible arrangement of the testing location according to actual testing needs.

[0042] Please refer to the attached Figure 1 -Attached Figure 8 A method for using a ball valve wear resistance detection device, used for a ball valve wear resistance detection device as described in the claim, comprising the following steps: 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; S2, install the ball valve, start the motor 17 to adjust the position of the clamping block 13 according to the specifications of the ball valve body 14, put the ball valve in the groove of the placement plate 20 and clamp it; S3, parameter setting, according to the detection requirements, adjust the electric push rod 5 to determine the friction pressure, set the motor 28 speed to control the ball valve rotation speed, operate the valve 10 and the blower 7 to simulate the corresponding environmental parameters; S4, detection and analysis, start the relevant components to carry out detection, turn off the power after completion, analyze and record the data to evaluate the wear resistance of the ball valve.

[0043] Specifically, the entire ball valve wear resistance testing device is pushed by external force through the rolling contact between the wheel 3 in the moving mechanism and the ground, so that it can move on the ground, thereby transferring the device to a suitable testing site. When reaching the predetermined position, the wheel brake 32 is operated, and the brake component inside the wheel brake 32 will be in close contact with the wheel body 30. According to the friction principle, the rotation of the wheel 3 is prevented by increasing the friction force, and the anti-slip strip 31 provided on the upper surface of the wheel brake 32 further enhances the friction effect, so that the device can be firmly fixed at the testing site to avoid accidental movement due to external factors (such as slight vibration caused by people walking, slight tilt of the ground, etc.).

[0044] According to the specifications and dimensions of the ball valve body 14, the motor 17 in the driving assembly is started, and the motor 17 drives the bidirectional screw 19 to rotate. Since the thread directions of the bidirectional screw 19 are opposite and it is threadedly connected to the middle of the slider 24, and the slider 24 is slidably connected in the slide groove 18 of the workbench 1, the rotation of the bidirectional screw 19 will cause the two sliders 24 to slide linearly along the slide groove 18 in opposite or opposite directions, thereby driving the clamping block 13 fixed on the top of the slider 24 to adjust the position. When the spacing of the clamping block 13 is adjusted to a suitable size, the ball valve is placed in a groove in the middle of the placement plate 20 with high smoothness and allowing the ball valve body 14 to rotate in place, and then the clamping block 13 clamps the ball valve to ensure that the ball valve will not be loose or shifted during the subsequent detection process, and can be stably in the detection position.

[0045] In terms of wear-resistant components, 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, and then the contact pressure between the two is determined, thereby simulating the friction conditions faced by the ball valve in actual use under different pressure levels.

[0046] For the part that drives the ball valve to rotate, by setting the speed of motor 28, the rotation of motor 28 is transmitted through the meshing of bevel gear 1 21 and bevel gear 2 22, driving the double-groove pulley 23 to rotate, and then transmitted to the pulley 26 through the transmission belt 27, thereby rotating the shaft 25 and the steering wheel 16 on its outer wall, and finally driving the ball valve to rotate at the set speed, simulating the actual rotation state of the ball valve under different working conditions.

[0047] In the auxiliary component, operating the valve 10 can control the connectivity between the water tank 12 and the air duct 8. Combined with the operation of the blower 7, according to the Bernoulli principle, when the blower 7 generates a large airflow, the pressure difference generated by the airflow will cause the water in the water tank 12 to be sucked out through the connecting pipe 11 and mixed with the airflow, and then sprayed out from the mist nozzle 9. By adjusting the opening and closing degree of the valve 10 and parameters such as the air volume of the blower 7, different environmental conditions such as dry airflow, humid dust, etc. can be simulated, thereby simulating the working conditions of the ball valve in an actual complex environment.

[0048] Start the motor 1 17, motor 2 28, electric push rod 5, blower 7 and other related components, and each component works together according to the previously set parameters. Motor 2 28 drives the ball valve to rotate, and the electric push rod 5 causes the friction plate 6 to apply the set friction pressure to the rotating ball valve. At the same time, the blower 7 creates corresponding environmental conditions to act on the ball valve, simulating the working state and wear environment of the ball valve under actual working conditions. During the detection process of a certain period of time, the wear-related data of various parts of the ball valve under this simulated working condition are collected. After the detection is completed, the power is turned off and the operation of various components is stopped. Then, professional data processing and analysis methods are used to organize and analyze the recorded data. For example, by comparing the changes in wear in different time periods and the differences in wear degrees under different working conditions, the wear resistance of the ball valve is comprehensively evaluated.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
