Description

Technical Field

[0001] This utility model belongs to the field of thermocouple leak detection technology, and in particular relates to an adjustable flange leak detection tool. Background Technology

[0002] In the industrial production field, thermocouples are key components for temperature measurement, and their quality and reliability are directly related to the stability and safety of many production processes. As an important component connecting thermocouples and equipment, the sealing performance of flanges is crucial. Once a leak occurs, it will not only affect the measurement accuracy of the thermocouple, but may also cause safety accidents. Therefore, accurate and efficient flange leak detection is indispensable.

[0003] However, existing flange leak detection fixtures are not easy to adapt to different flange specifications and sizes. The mounting hole sizes and arrangements of flanges vary greatly and there are many types. It is difficult to design a matching flange for each product for testing. In addition, they are very cumbersome to use, have poor versatility, and low practicality. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable flange leak detection fixture. By setting an adjustment mechanism, it solves the problems of existing flange leak detection fixtures, which are not easy to adapt to different flange specifications and sizes, and the flange mounting hole sizes and arrangements vary greatly. There are many types of flanges, making it difficult to design a matching flange for each product for testing. In addition, they are very cumbersome to use, have poor versatility, and low practicality.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an adjustable flange leak detection tool, including a support block, on which an adjustment mechanism and a detection mechanism are provided;

[0007] The adjustment mechanism includes two rectangular slots formed on the support block. T-shaped sliding grooves are formed on the inner walls of the front and rear sides of the two rectangular slots. T-shaped sliders are slidably connected to the inner walls of several T-shaped sliding grooves. Two square blocks are fixedly connected to the side of several T-shaped sliders that are close to each other. The detection mechanism includes a flange to be tested set above the support block.

[0008] Furthermore, each of the two square blocks is perforated with a bolt, and the two bolts are fixedly connected to the two square blocks respectively. The outer walls of the two bolts are threaded with nuts, and the bottoms of the two nuts are in contact with the flange to be tested.

[0009] Furthermore, a connecting block is fixedly connected to the top of the support block, an annular groove is formed on the top of the connecting block, an O-ring is fixedly connected to the inner wall of the annular groove, the top of the O-ring contacts the flange to be tested, and a cylindrical through groove is formed on the support block.

[0010] Furthermore, a thermocouple sealing block is provided on the top of the flange to be tested, an armored thermocouple is provided on the top of the thermocouple sealing block, and a cold junction lead is provided on the bottom of the thermocouple sealing block.

[0011] Furthermore, a cylindrical block is fixedly connected to the inner wall of the cylindrical through groove, an inner cavity is formed on the cylindrical block, a hollow block is connected to the bottom of the inner cavity, and a mating thread is formed on the outer wall of the hollow block.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting an adjustment mechanism, when installing the flange to be tested, push one of the bolts to make the square block slide in the limit of the two T-shaped sliders and the T-shaped groove to adjust its position to match the flange to be tested. Similarly, adjust the position of the other bolt, then insert the flange to be tested onto the two bolts, and screw the two nuts onto the two bolts respectively until the cylindrical through groove on the annular groove and the sealing surface of the flange to be tested meet the requirements. Stop tightening the two nuts, and the fit of the flange to be tested is fixed, so that it can adapt to different flange specifications and sizes. There is no need to design a matching flange for each product for testing, thereby improving the versatility and practical value of the device.

[0014] 2. By setting up a testing mechanism, at the start of the test, the mating thread on the inner cavity is screwed into the external water pressure source pipe through the hollow block. The thermocouple sealing block is installed on the flange to be tested, and the cold junction lead is placed into the inner cavity of the cylindrical block. Finally, the required water pressure is introduced from the outside through the hollow block. After stabilizing the pressure for a certain period of time, observe whether there is any leakage at the joint point between the product's thermocouple sealing block and the armored thermocouple. This completes the leak detection operation, which can quickly detect potential leaks in the flange and avoid adverse situations such as thermocouple measurement errors and media leakage caused by poor flange sealing, thus ensuring the safe and stable operation of related equipment.

Two square blocks 214 are fixedly connected to the sides of the several T-shaped sliders 213 that are close to each other. Bolts 215 penetrate each of the two square blocks 214, and the two bolts 215 are fixedly connected to the two square blocks 214 respectively. The outer wall of the support block 1 is threaded with nuts 216, and the bottom of the two nuts 216 are in contact with the flange 311 to be tested. The top of the support block 1 is fixedly connected with a connecting block 217, and the top of the connecting block 217 is provided with an annular groove 218.
