Abstract
Description
Technical Field
[0001] This utility model belongs to the field of gas tightness testing technology, and in particular relates to a gas tightness testing device. Background Technology
[0002] Hermetically sealed packaging plays a vital role in protecting electronic components from external environmental corrosion, thereby improving their reliability and stability. In fields such as aviation, aerospace, instrumentation, measurement, and special equipment, due to the special nature of the working environment, electronic components need to have higher durability and corrosion resistance. Therefore, the stability of hermetically sealed packaging has a crucial impact on product quality and performance.
[0003] However, the existing airtightness testing devices require complex preparation before testing, which requires staff to spend a lot of time on precise operations, which is time-consuming and laborious, greatly prolonging the testing time and thus reducing testing efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide an airtightness testing device. By setting up a testing mechanism, it solves the problem that the preparation work before testing is complicated in the use of existing airtightness testing devices, which requires staff to spend a lot of time on precise operation, which is time-consuming and laborious, greatly prolongs the testing time, and thus reduces the testing efficiency.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is an airtightness testing device, including a main pipe, on which a testing mechanism and a connecting mechanism are provided;
[0007] A connecting block is provided on the left side of the main pipe, and a handle is fixedly connected to the rear side of the connecting block. The connecting mechanism includes a connecting ring fixedly connected to the right side of the main pipe, and a threaded sleeve is rotatably connected to the outer wall of the connecting ring.
[0008] Furthermore, a threaded tube is fixedly connected to the left side of the first connecting block, a sealing ring is fixedly connected to the left side of the first threaded tube, a second connecting block is provided on the left side of the first connecting block, the second connecting block is adapted to the first threaded tube, a handle is fixedly connected to the bottom of the second connecting block, a sealing ring is fixedly connected to the inner wall of the second connecting block, and a thermocouple core is provided inside the first threaded tube.
[0009] Furthermore, a valve body is provided on the right side of the main pipeline, and a threaded pipe two is fixedly connected to the left side of the valve body. The threaded pipe two is adapted to the threaded sleeve one. A threaded pipe three is fixedly connected to the right side of the valve body. A threaded sleeve two is provided outside the threaded pipe three. The threaded sleeve two is adapted to the threaded pipe three. A connecting ring two is rotatably connected to the inner wall of the threaded sleeve two. A connecting pipe is fixedly connected to the right side of the connecting ring two.
[0010] This utility model has the following beneficial effects:
[0011] 1. By setting up a detection mechanism, the thermocouple core to be tested can be inserted into connecting block one and then further inserted into the main pipe. Then, connecting block two can be connected to threaded pipe one through the internal threads. After the thermocouple core is stuck between connecting block two and connecting block one, connecting block two can be tightened by handle one and handle two. At this time, under the action of sealing ring one and sealing ring two, the thermocouple core will be sealed to the main pipe. At this time, the detection foam can be applied to the edge of connecting block one, and then the valve body can be opened to inject compressed air from the connecting pipe into the main pipe. At this time, the foam at the position of connecting block one can be observed to determine whether the thermocouple core is leaking. This allows the thermocouple core to be tested to be installed in the device quickly and ensures the sealing of the device, speeding up the preparation work for testing, saving a lot of time, and thus improving the testing efficiency.
[0012] 2. By setting up a connection mechanism, when cleaning is required, the threaded sleeve two can be rotated to unscrew it from the threaded tube three, thereby disassembling the connecting tube through the connecting ring two. Then, the threaded sleeve one can be rotated to unscrew it from the threaded tube two, thereby removing the valve body through the connecting ring one. Similarly, the connecting block two can be unscrewed to complete the disassembly. Then, each component can be cleaned. After completion, the reverse operation can be used to restore the device, allowing it to be disassembled. During cleaning, each component of the device can be effectively cleaned, preventing corrosion of the components and thus avoiding a decrease in sealing performance, thereby extending the service life of the device.
[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
