Description

Technical Field

[0001] This application relates to the field of sealing testing technology, and in particular to a sealing performance testing device. Background Technology

[0002] Sealing performance testing is a quality control method that verifies whether a container, component, or system can effectively prevent leakage of media such as gases and liquids through specific methods and equipment. Its core purpose is to ensure that the product meets sealing standards under its intended use scenario, avoiding functional failure, safety risks, or performance degradation due to leakage. It is widely used in core industrial fields such as aerospace, automotive manufacturing, medical devices, electronic products, and packaging containers. The quality of sealing performance directly affects the safety, functionality, reliability, and service life of a product. Therefore, sealing performance testing is an indispensable part of product development, production quality inspection, and regular maintenance. Traditional testing devices are designed for specific, single-type workpieces or products, and are insufficient to meet the needs of flexible production and research with multiple varieties and small batches. Utility Model Content

[0003] To address the aforementioned technical problems, this application provides a sealing performance testing device that allows for the replacement of corresponding mounting plates according to different test samples, thus adapting to various test samples and meeting practical needs. The technical solution adopted is as follows: A sealing performance testing device includes a support and a testing tank, wherein a testing cavity with one end open is formed inside the testing tank, and an external connector is provided on the testing tank, and the testing tank is connected to the support. A connecting ring is disposed at the outer edge of the opening; Mounting plate, which is used to fix and install the test sample, and the mounting plate is detachably connected to the connecting ring; A detection component, connected to the detection tank, is used to detect the contents of the detection chamber.

[0004] Preferably, the detection assembly includes at least one first detection component for detecting the pressure of the medium inside the detection chamber, and at least one second detection component for detecting the temperature of the medium inside the detection chamber.

[0005] Preferably, the mounting plate and the connecting ring are sealed together.

[0006] Preferably, a plurality of disassembly components are provided between the mounting plate and the connecting ring.

[0007] Preferably, the disassembly components are evenly distributed around the mounting plate and the connecting ring in the circumferential direction.

[0008] Preferably, the support is movable.

[0009] Preferably, the system further includes a control cabinet electrically connected to the detection component.

[0010] Compared with the prior art, the beneficial effects of this application are as follows: This application allows for the installation and fixation of different test samples by disassembling and connecting the mounting plate to the test tank. This enables the installation and fixation of different test samples by replacing the corresponding mounting plate, thereby making it suitable for different test samples and improving the overall test diversity of the device. This avoids the problem of testing only one type of sample and meets the actual use requirements. At the same time, it can replace multiple tooling sets, reducing the complexity of tooling design and manufacturing costs. Secondly, the control cabinet can collect data (pressure, leakage, temperature) from the detection components in real time. The control cabinet can generate curves (pressure-time, leakage-time) based on the collected data to analyze the leakage rate with higher accuracy. Attached Figure Description

[0013] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0014] See Figure 1 The following is a further detailed description of the sealing performance testing device: It includes a support 10 and a testing container 20. The testing container 20 forms a testing chamber 200 with an opening 210 at one end, and an external connector 60 is provided on the testing container 20. The testing container 20 is connected to the support 10. The external connector 60 is used to connect to an external supply device, which can be a vacuum pump to extract gas from the testing chamber 200 to achieve negative pressure testing of the sample, or an air compressor to supply high-pressure gas to the testing chamber 200 to achieve positive pressure testing of the sample. In this embodiment, positive pressure testing is used, that is, high-pressure gas is supplied to the testing chamber 200, and the supplied gas is nitrogen or dry air.

[0015] A connecting ring 40 is provided at the outer edge of the opening 210. A mounting plate 30 is detachably connected to the connecting ring 40. The mounting plate 30 is used to fix and install the test sample. The test sample can be a sealed container, valve, etc. For example, if the sealed container is a valve, the mounting plate 30 can have a through hole. The valve to be tested is connected to the through hole through its own thread structure. The through hole connects the valve to be tested to the test chamber 200. The test chamber 200 is formed between the test tank 20, the mounting plate 30 and the test sample. The test chamber 200 is evacuated or supplied with high-pressure gas through the external connector 60, thereby realizing the sealing test of the test sample.

[0016] In this embodiment, a detection component 50 is also included. The detection component 50 is connected to the detection tank 20 and is used to detect the temperature and pressure of the gas inside the detection chamber 200. By cooperating with the detection component 50, the gas state inside the detection chamber 200 is detected to ensure that the gas inside the detection chamber 200 reaches a preset value, thereby ensuring detection accuracy.

[0017] This application improves the diversity of the device's testing capabilities by detaching and connecting the mounting plate 30 to the testing tank 20, and by replacing the corresponding mounting plate 30 according to different testing samples to install and fix the corresponding testing samples, thereby adapting to different testing samples and avoiding the use of a single testing sample to meet actual usage needs; at the same time, it can replace multiple tooling sets and reduce manufacturing costs.

[0018] The detection assembly 50 includes at least one first detection component 510 for detecting the pressure of the medium inside the detection chamber 200, and at least one second detection component 520 for detecting the temperature of the medium inside the detection chamber 200. Both the first detection component 510 and the second detection component 520 are embedded in the wall of the detection tank 20, and their detection ends extend into the detection chamber 200 to ensure accurate detection data. In this embodiment, there is one second detection component 520 and two first detection components 510, with the first detection component 510 located on both sides of the second detection component 520. The first detection component 510 is a pressure sensor, and the second detection component 520 is a temperature sensor. The number of the first detection component 510 and the second detection component 520 is not limited and can be set according to actual needs.

[0019] In this embodiment, a plurality of disassembly components 70 are provided between the mounting plate 30 and the connecting ring 40. As a feasible implementation, the disassembly components 70 can be bolt assemblies, and the mounting plate 30 and the connecting ring 40 are disassembled and connected via bolt assemblies. The disassembly components 70 are evenly distributed around the mounting plate 30 and the connecting ring 40 in the circumferential direction.

[0020] In embodiments not shown, the mounting plate 30 and the connecting ring 40 can also be detached and connected by means of threaded connection or other methods.

[0021] The mounting plate 30 and the connecting ring 40 are sealed together. A sealing gasket or sealing ring may be provided between the mounting plate 30 and the connecting ring 40 to prevent gas leakage from the detection chamber 200 between the mounting plate 30 and the connecting ring 40, thereby improving the accuracy of the detection.

[0022] The support 10 is movable to allow for the overall movement of the testing tank 20. Several traveling components, such as casters, can be arranged at the bottom of the support 10. These traveling components enable the flexible movement of the support 10, thereby shifting the testing tank 20 and improving the flexibility of the device.

[0023] It also includes a control cabinet, which is electrically connected to the detection component 50. The control cabinet includes a control panel. The control cabinet is integrated on the bracket 10 and is also electrically connected to the external supply device. Based on feedback from the detection component 50, the external supply device can be controlled according to preset parameters. Data (pressure, leakage, temperature) from the detection component can be collected in real time, and curves (pressure-time, leakage-time) can be generated to analyze the leakage rate with higher accuracy.

[0024] In use, a suitable mounting plate 30 is selected according to the test sample, and the test sample is installed on the test tank 20 through the mounting plate 30. The test tank 20, the mounting plate 30, and the test sample constitute a temporary, sealed test chamber 200 isolated from the outside. Nitrogen or dry air is supplied into the test chamber 200 through the external connector 60. The control cabinet controls the external connector 60 to close based on the feedback from the detection component 50, so that a stable pressure space is formed in the test chamber 200. Within a set time, the pressure change in the test chamber 200 is detected by the first detection component 510 to determine whether the test sample has a leak. The control cabinet analyzes the leakage rate by generating a curve based on the detection data of the detection component 50. After the test is completed, the gas in the test chamber 200 is released through the external connector 60, and then a new test sample is installed.
