Description

Technical Field

[0001] This utility model relates to the field of control valve performance measurement technology, specifically to a test system for measuring the performance of an aircraft anti-icing control valve. Background Technology

[0002] In high-altitude, high-speed, and low-temperature environments, aircraft are highly susceptible to icing. For example, icing of instruments can lead to malfunctions, icing of wing surfaces can deteriorate aerodynamic configurations, and icing of air intakes can cause engine blade breakage and wear.

[0003] To prevent these problems, anti-icing control valves and temperature sensors are typically installed in critical areas. The valves open and close based on temperature readings from the sensors, allowing hot air or anti-icing media to protect these critical areas. Therefore, the performance and reliability of the anti-icing control valve directly affect the safety of the aircraft during flight, making it necessary to measure its performance. Utility Model Content

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to fixed connection or setting, detachable connection or setting, or integral connection or setting; they can refer to direct connection or indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0022] like Figures 1-3 As shown, this embodiment provides a test system for measuring the performance of an aircraft anti-icing control valve, including a power control module, an anti-icing control valve voltage measurement module, and a gas source and pipeline pressure control module;

[0023] The power control module comprises a quick-connect connector, a multi-position switch, indicator lights, and a voltage regulator. The quick-connect connector is used to connect to the anti-icing control valve circuit to supply power to the anti-icing control valve. The multi-position switch controls the power supply to different control systems within the control valve. The indicator lights determine the circuit's on / off status. The multi-position switch has four positions: position one is off, position two is one circuit energized, position three is the other circuit energized, and position four is both circuits energized. The voltage regulator adjusts the voltage so that the power control module can provide 12~48V power to the anti-icing control valve.

[0024] The voltage regulator is used to connect the internal 24V power supply and the external power supply. When the multi-position switch 523 is adjusted to position 2, the voltage of the internal circuit is controlled by the voltage regulator; when adjusted to position 3, the internal voltage is controlled by the external voltage and does not pass through the voltage regulator; when adjusted to position 4, the quick-connect connectors 501~504 are powered by the external power supply and do not pass through the voltage regulator, while the quick-connect connectors 505~512 are powered by the internal power supply and the voltage can be adjusted by the voltage regulator.

[0025] The anti-icing control valve voltage measurement module 100 includes an image recognition module and a voltage measurement module. The image recognition module is used to identify the pointer direction, determine the valve opening, and feed back the theoretical voltage to the voltage measurement module. The voltage measurement module is used to receive the feedback voltage of the anti-icing control valve, compare the feedback voltage with the theoretical voltage, and provide the error between the two, which facilitates the subsequent correction of the anti-icing control valve.

[0026] It should be noted that the image recognition module uses existing technology, which utilizes convolutional neural networks to determine the specific value of the pointer opening, feeds back the corresponding theoretical voltage based on the relationship between the given pointer opening and the theoretical voltage, and feeds back the theoretical voltage to the voltage measurement module.

[0027] The gas source and pipeline pressure control module 200 includes a high-pressure gas source, an electric pressure reducing valve, a pressure sensor, a pressure stabilizing tank, a gate valve, a safety valve, a flow meter, and a pressure reducing valve. The high-pressure gas source is connected to the electric pressure reducing valve, which is then connected to the pressure sensor. The purpose of the electric pressure reducing valve is to ensure that the pipeline does not experience overpressure and to maintain the pipeline flow rate. The pressure stabilizing tank is used to stabilize the pressure and is equipped with a safety valve. The gate valve controls the connection between the pipeline and the pressure stabilizing tank, ensuring that when the pressure stabilizing tank reaches the target pressure, the pipeline is connected, allowing the pipeline to instantly reach the required pressure. When the pipeline pressure exceeds the maximum target pressure by 20%, the safety valve opens to ensure pipeline safety. The flow meter and pressure reducing valve are used to ensure the output flow rate within the pipeline, aiming to ensure that the output flow rate of hot air or anti-icing medium is consistent with that of the normal environment.

[0028] It should be noted that the pipes at both ends connected to the anti-icing control valve can be replaced, allowing the piping system to be connected to anti-icing control valves of different diameters and connection methods; ensuring the flexibility and versatility of the connection between the piping system and the anti-icing control valve.

[0029] Specifically, such as Figure 1As shown, the connection method of the gas source and pipeline pressure control module is as follows: pressure reducing valve 1 is connected to flow meter 2, flow meter is connected to aircraft anti-icing control valve 3 through pipeline, aircraft anti-icing control valve 3 is connected to gate valve 7 through pipeline, and safety valve 6 is added to the pipeline; gate valve 7 is connected to pressure stabilizing tank 8, pressure sensor 9 is installed on pressure stabilizing tank 8, pressure stabilizing tank 8 is connected to electric pressure reducing valve 10, and the other end of electric pressure reducing valve 10 is connected to high-pressure gas source 12.

[0030] This application relates to a test system for evaluating the normal operation and performance of an aircraft anti-icing control valve when a pressure difference is established on both sides. The test system can provide a 12-48V power supply to the anti-icing control valve and a 0-5MPa air pressure to reproduce the actual power supply and ambient pressure in the actual operating environment of the anti-icing control valve. The test measurement system can measure the anti-icing control valve opening pointer, feedback voltage, and the relationship between the two, ensuring that the voltage value accurately represents the valve opening during actual use.

[0031] Experimental procedure:

[0032] 1. During pressurization of the pressure stabilizing tank: The power and signal lines of the pressure sensor 9 and the electric pressure reducing valve 11 are connected to the pressure reducing valve control system 10. When the target pressure is input into the pressure reducing valve control system 11, the electric pressure reducing valve 10 automatically opens and automatically adjusts the pressure until the target pressure is reached in the pressure stabilizing tank 9.

[0033] 2. During commissioning: The anti-icing control valve 3 is not connected to the pipeline, and the flow meter 2 is connected to the gate valve 7 (i.e., the anti-icing control valve is not connected to the pipeline, while other connections are normal). Open the gate valve 7, and adjust the pressure reducing valve 1 according to the target flow rate and the flow rate displayed on the flow meter 2 until the target flow rate matches the flow meter reading. Then close the gate valve 7. After commissioning, the pipeline should be connected as follows: Figure 1 Connect sequentially.

[0034] 3. Pre-test preparation: For the anti-icing control valve 3 circuit and power control module, set all multi-position switches to position 1 to disconnect all circuits. Confirm that the power supply voltage of the anti-icing control valve 3 matches the control voltage. If they match, adjust the multi-position switches to position 2; if they do not match, adjust them to position 4. The external power supply provides voltage to the anti-icing control valve 3 power supply circuit, and the internal power supply provides voltage to the anti-icing control valve 3 control circuit. The feedback voltage of the anti-icing control valve 3 is connected to the voltage measurement module 5. The image recognition module 4 is used to monitor and identify the valve pointer opening of the anti-icing control valve 3. The image recognition module 4 is connected to the voltage measurement module 5 to feed back the theoretical voltage to the voltage measurement module.

[0035] 4. Preliminary test: After the preparations for the test are completed, power the anti-icing control valve 3 through the power control module, observe the relevant parameters of the voltage measurement module 5 and after the valve opens and closes normally, the test can proceed normally.

[0036] 5. Formal test: Open gate valve 7, supply power to the power supply circuit of anti-icing control valve 3 through power control module, then power control module controls the control circuit voltage of anti-icing control valve 3 to make anti-icing control valve 3 operate, and record theoretical voltage and feedback voltage and the relationship between the two through voltage measurement module 5.

[0037] It should be noted that this utility model does not involve innovation in methods, and all electronic and electrical components involved are purchased externally and adopt existing technologies.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
