[0037] As described in the background, related techniques for detecting valve operating noise involve connecting the valve to a pipe, introducing air into the pipe, and using a noise sensor to detect the noise generated by the air as it flows through the valve. However, this detection method can only detect valve noise generated under normal pressure, resulting in poor reliability.

[0038] Based on this, the noise detection device for pipeline components provided by the present application is provided with a silent chamber, a sealed cabin, a pressurization assembly and a detection assembly, wherein the sealed cabin is provided in the silent chamber. The pressurization assembly includes a pressurization component and an air intake pipe. The pressurization component is provided outside the silent chamber. The silent chamber isolates the pressurization component from the sealed cabin to reduce the interference of the noise of the pressurization component on the detection results. The air intake pipe connects the pressurization component and the sealed cabin. The pressurization component inputs gas into the sealed cabin through the air intake pipe to change the air pressure in the sealed cabin. The sealed cabin is used to connect to the component to be tested, and the sealed cabin can provide a controllable pressure environment for the component to be tested. The detection assembly includes at least one noise detection component, which is provided in the silent chamber and is used to detect the noise of the component to be tested. The noise detection device for pipeline components provided by the present application can detect the noise generated by the pipeline component under different pressures, thereby improving the reliability of the detection results.

[0039] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0040] Reference Figure 1 As shown, the noise detection device for pipeline elements provided in the present application includes a quiet chamber 100 , a sealed cabin 200 , a pressurizing assembly 300 and a detection assembly 400 , wherein the sealed cabin 200 is disposed in the quiet chamber 100 .

[0041] The booster assembly 300 includes a booster 310 and an air intake pipe 320. The booster 310 is arranged outside the silent chamber 100. The air intake pipe 320 connects the booster 310 and the sealed cabin 200. The booster 310 inputs gas into the sealed cabin 200 through the air intake pipe 320 to change the air pressure in the sealed cabin 200. The sealed cabin 200 is used to connect to the component under test 10.

[0042] The detection assembly 400 includes at least one noise detection element 410 . The noise detection element 410 is disposed in the quiet chamber 100 and is used to detect noise of the device under test 10 .

[0043] It should be noted that the pipeline components can be valves such as regulating valves, stop valves, ball valves, butterfly valves, safety valves, pressure relief valves and check valves, or other components, and the embodiments of the present application do not impose too many restrictions on this.

[0044] It is understood that the sealed cabin 200 is disposed within the silent room 100, which can provide a soundproof environment to prevent external noise from interfering with the detection process, thereby helping to improve the accuracy and reliability of noise detection. In a specific implementation, the floor of the silent room 100 can be treated as a load-bearing structure.

[0045] Gas pressure can be generated by providing the booster 310. It should be noted that the booster 310 can be a booster fan, which can be installed on a fan bracket.

[0046] The air intake pipe 320 is used to deliver gas to the sealed chamber 200. By supplying gas to the sealed chamber 200, the pressurizing element 310 and the air intake pipe 320 can adjust the pressure within the sealed chamber 200 to simulate test conditions with varying pressures. In a specific implementation, a mounting hole can be provided in the silent chamber 100, through which the air intake pipe 320 connects the pressurizing element 310 with the sealed chamber 200. The mounting hole is sealed and noise-reducing. For example, the air intake pipe 320 can be made of a steel pipe, which can be supported by a welded bracket mounted on the outer wall of the silent chamber 100.

[0047] It should also be noted that since the sealed cabin 200 is arranged in the silent chamber 100, the sealed cabin 200 is used to connect to the component to be tested 10, and since the booster 310 is arranged on the outside of the silent chamber 100, the silent chamber 100 isolates the booster 310 from the sealed cabin 200 to reduce the interference of the noise of the booster 310 on the test results.

[0048] Sealed chamber 200 is connected to DUT 10 and provides a controllable pressure environment for DUT 10 during testing. By adjusting the pressure within sealed chamber 200, operating conditions at different pressures can be simulated to detect the noise characteristics of DUT 10 under different pressures, thereby improving the reliability of the test results.

[0049] The noise detector 410 is used to capture and measure the noise generated by the device under test 10. For example, the noise detector 410 can be a noise sensor that can collect noise data to help analyze the noise characteristics of the device under test 10 under different pressure conditions. This data can be used to improve device design, optimize operating conditions, or perform quality control.

[0050] It is understood that the noise detection device for pipeline components provided in the embodiments of the present application is to accurately measure the noise of pipeline components in a pressure-controlled and soundproof environment. By simulating working conditions of different pressures, the noise detection element 410 can provide noise characteristic data.

[0051] In some embodiments, reference Figure 1 As shown, the detection assembly 400 further includes a first pressure detection member 420 . The first pressure detection member 420 is disposed on the sealed cabin 200 and is used to detect the pressure inside the sealed cabin 200 .

[0052] Specifically, the first pressure detection component 420 is used to monitor the pressure within the sealed chamber 200 in real time. By monitoring and recording the pressure within the sealed chamber 200, it is possible to ensure that the noise detection data is associated with specific pressure conditions, which helps to analyze the noise characteristics of the device under test 10 under different pressures. For example, the first pressure detection component 420 can be a pressure sensor.

[0053] In some embodiments, reference Figure 1 As shown, the boost assembly 300 further includes an exhaust pipe 330 , which is in communication with the sealed cabin 200 to discharge part of the gas.

[0054] It can be understood that the exhaust pipe 330 can discharge part of the gas from the sealed cabin 200, thereby adjusting the pressure in the cabin, and can control the air pressure in the sealed cabin 200 to simulate operating conditions of different pressures.

[0055] Specifically, when the pressure in the sealed chamber 200 needs to be quickly reduced, the exhaust pipe 330 can quickly release gas. By controlling the discharge of gas, the exhaust pipe 330 can achieve dynamic balance of pressure in the sealed chamber 200, providing stable testing conditions and avoiding inaccurate test data caused by pressure fluctuations.

[0056] The exhaust pipe fitting 330 increases the flexibility of the test and can perform noise detection under various pressure conditions without changing equipment or performing complex reconfiguration, making it easy to operate.

[0057] In some embodiments, reference Figure 1 As shown, the exhaust pipe 330 is provided with a regulating valve 331 , which is used to regulate the flow rate of the exhaust gas discharged from the exhaust pipe 330 .

[0058] It can be understood that the regulating valve 331 can accurately control the gas flow in the exhaust pipe 330, thereby adjusting the pressure in the sealed cabin 200, so that the sealed cabin 200 maintains the required pressure conditions during the detection process, ensuring the accuracy and repeatability of the test.

[0059] Regulating valve 331 allows for slow gas release, preventing drastic pressure fluctuations and maintaining a stable pressure within sealed chamber 200, thereby obtaining stable noise measurement data. Regulating valve 331 can easily simulate different pressure conditions within the same test setup, increasing test flexibility and diversity, and improving the reliability of test results.

[0060] In some embodiments, reference Figure 1 As shown, the noise detection device for pipeline elements further includes a controller 500 , which is disposed on the outer wall of the silent chamber 100 , and the pressurizing component 310 , the first pressure detecting component 420 and the regulating valve 331 are all connected to the controller 500 through an electrical system.

[0061] It is understandable that the controller 500 can automatically control the pressurizing component 310, the first pressure detecting component 420 and the regulating valve 331, so that the system can automatically adjust the pressure in the sealed cabin 200 according to the preset test parameters, thereby simplifying the operation process.

[0062] It should be noted that the connection between the controller 500 and the first pressure detection component 420 allows the controller 500 to monitor the pressure in the sealed cabin 200 in real time and make feedback adjustments based on the detected pressure data, which helps to maintain stable test conditions.

[0063] The controller 500 can precisely control the opening of the regulating valve 331 to adjust the exhaust flow rate, thereby achieving precise control of the pressure in the sealed cabin 200 to ensure the accuracy and repeatability of noise detection.

[0064] In a specific implementation, the boost component 310 can be a boost fan. When the first pressure detection component 420 detects that the pressure in the sealed cabin 200 is greater than or equal to the preset pressure, the controller 500 can control the boost fan to reduce the speed to 50% of the rated speed, and control the regulating valve 331 to change the valve opening until the pressure fluctuation in the sealed cabin 200 is less than 1 kPa, and detect the performance of the component to be tested under the preset pressure.

[0065] It should also be noted that the controller 500 can record pressure and operating data during the test process, providing a basis for subsequent analysis and optimization. The controller 500 also allows operators to input test parameters, monitor system status, and view real-time data, improving the operability of the system.

[0066] In some embodiments, a pressure relief valve 220 is provided on the sealed cabin 200 , and the pressure relief valve 220 is used to control the pressure relief of the sealed cabin 200 .

[0067] It is understood that the pressure relief valve 220 can be used to prevent excessive pressure in the sealed cabin 200. When the pressure exceeds a set safety threshold, the pressure relief valve 220 is opened to release excess gas, thereby preventing equipment damage and ensuring the safety of operators.

[0068] It should be noted that the pressure relief valve 220 may be an automatic pressure relief valve 220 to improve the convenience of system operation.

[0069] During specific implementation, a manual valve 230 may be provided on the sealed cabin 200 to further ensure the safety of the test process.

[0070] In some embodiments, reference Figure 1 As shown, a connecting pipe 210 is provided on the sealed cabin 200 , and the connecting pipe 210 is used to connect the device under test 10 and the sealed cabin 200 .

[0071] The connecting pipe 210 provides a channel for delivering the gas in the sealed chamber 200 to the device under test 10, so that the device under test 10 maintains a stable pressure condition during the test process, thereby ensuring the accuracy of the test results.

[0072] During specific implementation, the connection pipe 210 needs to consider sealing and pressure resistance to prevent gas leakage and ensure safe operation of the device.

[0073] In some embodiments, reference Figure 1 As shown, the detection assembly 400 further includes a flow detection component 430 , which is used to connect with the element to be tested 10 to detect the gas flow in the element to be tested 10 .

[0074] It can be understood that the flow detection element 430 is used to monitor the gas flow in the device under test 10 in real time, so as to understand the noise characteristics of the device under test 10 under different flow conditions.

[0075] By recording gas flow data, the noise level can be associated with specific flow conditions, which helps to analyze the causes of noise and the impact of flow changes on noise. The data provided by the flow detection element 430 can be used to evaluate the performance of the element to be tested 10 under different flow conditions.

[0076] It should be noted that the flow detection component 430 can also be connected to the controller 500 through an electrical system. The flow detection component 430 can feed back flow data to the controller 500, and the controller 500 adjusts the operating parameters of the boost component 310 and the regulating valve 331 to maintain the required flow conditions.

[0077] In some embodiments, reference Figure 1 As shown, the detection assembly 400 further includes a second pressure detection member 440 . The second pressure detection member 440 is used to connect with the device under test 10 to detect the pressure inside the device under test 10 .

[0078] Specifically, the second pressure detection component 440 is used to monitor the pressure inside the DUT 10 in real time. By recording the pressure data inside the DUT 10, the noise level can be associated with the specific pressure conditions, which helps to analyze the impact of pressure changes on noise.

[0079] In some embodiments, reference Figure 1 As shown, the noise detection device for the pipeline element further includes at least one silencer 600 , and the silencer 600 is provided on at least one of the intake pipe 320 and the exhaust pipe 330 .

[0080] Specifically, the muffler 600 is used to reduce the noise generated during the gas flow process. By installing the muffler 600 on the intake and / or exhaust pipe 330, the interference of the airflow noise on the detection environment can be effectively reduced, thereby improving the accuracy and reliability of noise detection. For example, the muffler 600 can be a muffler.

[0081] In some embodiments, the detection assembly 400 may further include a temperature detector 450, which is disposed on the intake pipe 320 to detect the temperature of the gas within the intake pipe 320. A pressure sensor and a flow sensor may also be disposed on the intake pipe 320 to detect the pressure and flow of the gas within the intake pipe 320. A flow sensor may also be disposed on the exhaust pipe 330 to detect the flow of the gas within the exhaust pipe 330. A three-way reversing valve 700 may also be disposed on the exhaust pipe 330 to change the direction of gas flow.

The sealed cabin 200 is disposed within the silent chamber 100. The pressurizing assembly 300 comprises a pressurizing component 310 and an air intake pipe 320. The pressurizing component 310 is disposed outside the silent chamber 100. The silent chamber 100 isolates the pressurizing component 310 from the sealed cabin 200 to reduce interference with the detection results caused by the noise of the pressurizing component 310. The air intake pipe 320 connects the pressurizing component 310 with the sealed cabin 200. The pressurizing component 310 inputs gas into the sealed cabin 200 through the air intake pipe 320 to change the air pressure within the sealed cabin 200. The sealed cabin 200 is used to connect to the component under test 10, and the sealed cabin 200 can provide a controllable pressure environment for the component under test 10.
