[0048] Reference Figure 1 As shown in the figure. This specification provides a throttle valve failure simulation device.

[0049] The throttle valve failure simulation device is used to simulate the erosion, wear, vibration and noise of the throttle valve under high pressure during actual operation.

[0050] In some embodiments, refer to Figure 1 and Figure 2 The throttle valve fault simulation device includes any one or more of the following: a first medium input component 1, a second medium input component 2, a mixing component 3, a throttle valve 4, and a monitoring unit 5.

The solid-liquid flow meter 52 can monitor the solid-liquid flow rate between the second medium input component 2 and the mixing component 3 and send the solid-liquid flow rate value to the computer device 6. The computer device 6 can generate a solid-liquid flow control signal based on the solid-liquid flow rate value and send the solid-liquid flow control signal to the second medium input component 2 to control the flow rate of the solid-liquid medium input into the second medium input component 2 in real time, thereby realizing closed-loop control of the solid-liquid medium flow rate in the throttle valve fault simulation device.

[0056] In some embodiments, refer to Figure 2 The throttle valve failure simulation device further includes a gas control component 7. The gas control component 7 can be used to control the flow rate and pressure of the gas medium input by the first medium input component 1. The gas control component 7 may include a pressure reducing valve 71, a flow regulating valve 72, and a check valve 73. The pressure reducing valve 71 can be used to reduce the pressure of the gas medium supplied by the first medium input component 1. The flow regulating valve 72 can be used to regulate the flow rate of the gas medium supplied by the first medium input component 1. The check valve 73 can be used to prevent the backflow of the gas medium supplied by the first medium input component 1.

[0057] The gas control component 7 can be connected to the first medium input component 1 via a pipeline to control the flow rate and pressure of the gas medium delivered by the first medium input component 1. The gas control component 7 can be connected to a computer device via wired and / or wireless means to receive pressure reduction control signals, flow regulation control signals, and check valve control signals generated by the computer device, thereby controlling the flow rate and pressure of the gas medium delivered by the first medium input component 1.

The pressure reducing valve 71 can be connected to a computer device via wired and / or wireless means to receive pressure reduction control signals generated by the computer device, thereby reducing the pressure of the gas medium delivered by the first medium input component 1. The flow regulating valve 72 can be connected to the pressure reducing valve 71 via a pipeline to regulate the flow rate of the gas medium delivered by the first medium input component 1. The flow regulating valve 72 can be connected to a computer device via wired and / or wireless means to receive flow regulation control signals generated by the computer device, thereby regulating the flow rate of the gas medium delivered by the first medium input component 1. Check valve 73 can be connected to flow regulating valve 72 via a pipeline to prevent backflow of the gaseous medium supplied by the first medium input component 1.

Mixing component 3 can be connected to check valve 73 via a pipeline to receive the gaseous medium supplied by the first medium input component 1.

[0058] In some embodiments, refer to Figure 2 The monitoring unit 5 may include a gas flow meter 51. The gas flow meter 51 can be used to monitor the gas flow rate between the first medium input component 1 and the mixing component 3. The computer device 6 can send a gas control signal to the gas control component 7 based on the gas flow rate monitored by the gas flow meter 51, thereby achieving closed-loop control of the gas medium flow rate in the throttle valve fault simulation device. Through closed-loop control of the gas medium flow rate, a flow medium with controllable flow velocity can be applied to the throttle valve 4, which helps to simulate the working state of the throttle valve 4 under different flow velocities. For example, the computer device 6 can acquire the gas flow rate monitored by the gas flow meter 51 and generate a gas control signal, which can then control the flow regulating valve 72, thereby adjusting the gas flow rate between the first medium input component 1 and the mixing component 3.

[0059] The gas flow meter 51 can be connected to the flow regulating valve 72 via a pipeline to monitor the gas flow rate between the first medium input component 1 and the mixing component 3. The check valve 73 can be connected to the gas flow meter 51 via a pipeline to prevent the backflow of the gas medium delivered by the first medium input component 1.

[0060] In practical applications, the gas flow meter 51 can monitor the gas flow rate between the first medium input component 1 and the mixing component 3 in real time and send the gas flow rate value to the computer device 6. The computer device 6 can generate a gas control signal based on the received gas flow rate value and send the gas control signal to the gas control component 7. The gas control component 7 can adjust the gas flow rate between the first medium input component 1 and the mixing component 3 according to the gas control signal. For example, the gas control signal can specifically control the flow regulating valve 72 to adjust the gas flow rate between the first medium input component 1 and the mixing component 3 to a set flow rate value, thereby realizing closed-loop control of the gas medium flow rate in the throttle valve fault simulation device.

[0061] In some embodiments, refer to Figure 2 The throttle valve failure simulation device also includes a stirring tank 8. The stirring tank 8 can be used to supply solid-liquid media to the second media input component 2. The stirring tank 8 can also receive mixed media flowing out through the throttle valve 4 and supply solid-liquid media flowing out through the throttle valve to the second media input component, achieving the recycling of the solid-liquid media. An opening 81 is provided at the top of the stirring tank 8, through which a set proportion of solid and liquid media can be added. The stirring tank 8 has a built-in stirring motor 82. After solid and liquid media are added to the stirring tank 8 through the opening 81, the computer equipment can generate a stirring control signal to control the stirring motor 82 to operate, stirring the solid and liquid media to obtain a set proportion of solid-liquid media.

[0062] The mixing tank 8 can be connected to the throttle valve 4 via a pipeline to receive the mixed medium flowing out of the throttle valve 4. The gaseous medium in the mixed medium can escape through the opening 81 at the top of the mixing tank 8. The mixing tank 8 can also be connected to the second medium input component 2 via a pipeline to transport the solid-liquid medium in the mixed medium flowing out of the throttle valve 4 to the second medium input component 2. The mixing tank 8 can be connected to the computer device 6 via wired and / or wireless means to receive the stirring control signal generated by the computer device 6, and to start the stirring motor 82 according to the received stirring control signal to stir the solid medium and liquid medium to obtain a solid-liquid medium.

[0063] In practical applications, solid and liquid media can be added through opening 81 of the mixing tank 8. For example, solid media such as sand can be poured into the mixing tank 8 through opening 81, and liquid media such as water can be injected into the mixing tank 8 by connecting a water pipe to opening 81. The computer device 6 generates a stirring signal and sends it to the mixing tank 8. The mixing tank 8 can then start the stirring motor 82 according to the stirring control signal to stir the solid and liquid media to generate a solid-liquid medium. The mixing tank 8 can also transport the solid and liquid media to the second media input component 2. After the throttle valve 4 is eroded by the mixed media, the mixing tank 8 can also be used to recover the solid and liquid media in the eroded mixed media, and the gaseous media in the mixed media can escape through opening 81.

[0064] In some embodiments, refer to Figure 2 The throttle valve failure simulation device also includes a drain component 9. The drain component 9 is used to discharge solid-liquid media. The drain component includes a drain valve 91 and a drain pump 92. The drain valve 91 can be used to control whether to discharge solid-liquid media. The drain pump 92 can be used to pump out the solid-liquid media discharged via the drain valve 91.

[0065] The drain component 9 can be connected to the mixing tank 8 via a pipeline to discharge the solid-liquid medium from the mixing tank 8. The drain valve 91 can be connected to the mixing tank 8 via a pipeline to control whether to discharge the solid-liquid medium from the mixing tank 8. The drain valve 91 can be connected to the computer device 6 via wired and / or wireless means to receive drain valve control signals generated by the computer device 6, and to open the drain valve 91 to discharge the solid-liquid medium from the mixing tank 8 according to the received drain valve control signals. The drain pump 92 can be connected to the drain valve 91 via a pipeline to pump out the solid-liquid medium discharged through the drain valve 91. The drain pump 92 can be connected to the computer device 6 via wired and / or wireless means to receive drain pump control signals generated by the computer device 6, and to open the drain pump 92 and pump out the solid-liquid medium discharged from the mixing tank 8 through the drain valve 91 according to the received drain pump control signals.

[0066] In practical applications, after erosion is completed, the first medium input component 1, the second medium input component 2, the mixing component 3, the stirring tank 8, and related pipelines can be cleaned. The computer device 6 can generate a drain valve control signal to open the drain valve 91 and a drain pump control signal to open the drain pump 92, thereby discharging the corresponding solid-liquid media while cleaning the first medium input component 1, the second medium input component 2, the mixing component 3, the stirring tank 8, and related pipelines. After cleaning, the drain valve 91 and the drain pump 92 can be opened again to discharge the remaining solid-liquid media.

[0067] In some embodiments, refer to Figure 2The monitoring unit 5 further includes a sound sensor 53, a displacement sensor 54, a first pressure transmitter 55, and a second pressure transmitter 56. The sound sensor 53 can be used to monitor the sound signal generated when the throttle valve 4 is eroded. The displacement sensor 54 can be used to monitor the vibration signal generated when the throttle valve 4 is eroded. The first pressure transmitter 55 can be used to monitor the first pressure change value generated when the throttle valve 4 is eroded. The second pressure transmitter 56 can be used to monitor the second pressure change value generated when the throttle valve 4 is eroded. The computer device 6 can collect the first and second pressure change values ​​when the throttle valve 4 is eroded. Based on the first and second pressure change values, the computer device 6 can generate a pressure control signal and send it to the pressure reducing valve 71 in the first medium input component 1 and the gas control component 7, thus realizing closed-loop pressure control in the throttle valve fault simulation device. For example, in the throttle valve failure simulation device, when the pressure is high, the pressure control signal can be used to control the pressure reducing valve 71 to decrease the pressure of the gas medium; when the pressure is low, the pressure control signal can be used to control the first medium input component 1 to increase the pressure of the gas medium. Through closed-loop control of the gas medium pressure, a pressure-controllable flowing medium can be applied to the throttle valve 4, which helps simulate the working state of the throttle valve 4 under flowing media with different pressures. The sound sensor 53 can be placed on the surface and / or inside the throttle valve 4 to detect the sound signal generated when the throttle valve 4 is eroded. The sound sensor 53 can be connected to the computer device 6 via wired and / or wireless means to send the monitored sound signal generated when the throttle valve 4 is eroded to the computer device. The displacement sensor 54 can be placed on the surface and / or inside the throttle valve 4 to monitor the vibration signal generated when the throttle valve 4 is eroded. The displacement sensor 54 can be connected to the computer device 6 via wired and / or wireless means to send the monitored vibration signal generated when the throttle valve 4 is eroded to the computer device 6. A first pressure transmitter 55 can be placed between the mixing component 3 and the throttle valve 4 via a pipeline to monitor the first pressure change value generated when the throttle valve 4 is eroded. The first pressure transmitter 55 can be connected to a computer device 6 via wired and / or wireless means to transmit the monitored first pressure change value generated when the throttle valve 4 is eroded to the computer device. A second pressure transmitter 56 can be placed between the throttle valve 4 and the mixing tank 8 via a pipeline to monitor the second pressure change value generated when the throttle valve 4 is eroded. The second pressure transmitter 56 can be connected to the computer device 6 via wired and / or wireless means to transmit the monitored second pressure change value generated when the throttle valve 4 is eroded to the computer device.

[0068] In practical applications, the first pressure transmitter 55 and the second pressure transmitter 56 can monitor in real time the first pressure change between the mixing component 3 and the throttle valve 4, and the second pressure change between the throttle valve 4 and the mixing tank 8 when the throttle valve 4 is eroded. The computer device 6 can collect the first and second pressure change values ​​and generate pressure control signals, which are then sent to the first medium input component 1 and the gas control component 7. The first medium input component 1 can control the pressure of the gas medium it delivers according to the pressure control signal. The gas control component 7 can adjust the gas pressure between the first medium input component 1 and the mixing component 3 according to the pressure control signal. For example, the pressure reducing valve 71 can be controlled by the pressure control signal to reduce the gas pressure between the first medium input component 1 and the mixing component 3 to a set pressure value, thereby realizing closed-loop control of the gas medium pressure in the throttle valve failure simulation device.

[0069] In some embodiments, refer to Figure 3 The throttle valve 4 may include a valve stem 41, a valve cover 42, and a valve body 43. The valve stem 41 can control the opening degree of the throttle valve 4, which helps to simulate the erosion and wear, vibration, and noise of the throttle valve 4 during actual operation under different erosion pressures and flow rates at different opening degrees.

[0070] The throttle valve 4 can be connected to the computer device 6 via wired and / or wireless means to receive valve stem control signals sent by the computer device 6 to adjust the opening of the throttle valve 4, thereby limiting the upper limit of the flow rate of the mixed medium entering the throttle valve 4. A sound sensor 53 can be embedded in the surface of the valve stem 41 to monitor the sound signal generated when the throttle valve 4 is eroded. A displacement sensor 54 can be embedded in the surface of the valve stem 41 to monitor the vibration signal generated when the throttle valve 4 is eroded.

[0071] In some embodiments, the computer device 6 is further configured to establish a fault diagnosis model for the throttle valve 4 based on information from the erosion process. The computer device 6 can acquire the sound signal, vibration signal, and first and second pressure change values ​​of the throttle valve 4 during erosion, and establish a fault diagnosis model relating the first and second pressure change values ​​of the throttle valve 4 during erosion, as well as the sound and vibration signals.

[0072] Computer device 6 can be connected to sound sensor 53 via wired and / or wireless means to receive sound signals generated when throttle valve 4 is eroded, as monitored by sound sensor 53. Computer device 6 can be connected to displacement sensor 54 via wired and / or wireless means to receive vibration signals generated when throttle valve 4 is eroded, as monitored by displacement sensor 54. Computer device 6 can be connected to first pressure transmitter 55 via wired and / or wireless means to receive a first pressure change value generated when throttle valve 4 is eroded, as monitored by first pressure transmitter 55. Computer device 6 can be connected to second pressure transmitter 56 via wired and / or wireless means to receive a second pressure change value generated when throttle valve 4 is eroded, as monitored by second pressure transmitter 56.

[0073] In practical applications, the sound sensor 53 and displacement sensor 54 can be placed on the surface and / or inside the throttle valve 4 to monitor the sound and vibration signals generated when the throttle valve 4 is eroded. The first pressure transmitter 55 can be placed between the mixing component 3 and the throttle valve 4 to monitor the first pressure change value generated when the throttle valve 4 is eroded. The second pressure transmitter 56 can be placed between the throttle valve 4 and the mixing tank 8 via a pipeline to monitor the second pressure change value generated when the throttle valve 4 is eroded. The computer device 6 can collect these sound signals, vibration signals, the first pressure change value, and the second pressure change value, and establish a throttle valve fault diagnosis model relating the first and second pressure change values, as well as the sound and vibration signals. For example, the average pressure change can be calculated based on the first and second pressure change values, and the throttle valve 4 can be classified into different operating state levels according to the frequency and amplitude of the sound and pressure signals. This yields the frequency and amplitude ranges of the sound and pressure signals corresponding to different operating state levels of the throttle valve 4, thus establishing a mapping relationship between the average pressure change and different operating state levels.

[0074] In practical applications, computer device 6 can also collect the gas flow rate value of gas flow meter 51, the solid-liquid flow rate value of solid-liquid flow meter 52, and the opening degree of valve stem 41 of throttle valve 4. This allows for the direct establishment of a throttle valve fault diagnosis model using machine learning algorithms. For example, the gas flow rate value, solid-liquid flow rate value, opening degree, first pressure change value, and second pressure change value can be used as input parameters for the machine learning model, while sound and vibration signals can be used as output parameters. The model can be trained until its evaluation index reaches a preset threshold, thus obtaining the throttle valve fault diagnosis model. Computer device 6 can also collect these gas flow rate values, solid-liquid flow rate values, opening degree, first pressure change value, second pressure change value, sound signal, and vibration signal to establish a throttle valve operating status database. This database can be referenced and compared during throttle valve operating status analysis to reduce the probability of throttle valve failure.

[0075] As can be seen from the above, the throttle valve failure simulation device provided in this specification applies a mixed medium impact flow with high pressure and high flow rate to the throttle valve through closed-loop control of medium pressure and medium flow rate to simulate the actual operation process of the throttle valve. This fills the gap in the research of related equipment for failure wear testing machines under high pressure, and is of great significance for exploring the erosion wear, vibration and noise of the throttle valve during actual operation and analyzing the working state of the throttle valve.
