[0002] As key components, the pressure-bearing performance of pipe fittings directly affects the safety and efficiency of equipment. They must undergo rigorous pressure testing before leaving the factory. Traditional test fixtures are mostly of fixed size, which is difficult to adapt to pipe fittings of different lengths. They need to be frequently replaced or manually positioned, which is cumbersome and can easily lead to poor sealing due to misalignment, causing pressure leakage or reading deviation, affecting the accuracy and reliability of test results.

[0003] Existing testing methods often require manual pressure application or the use of simple tools, resulting in unstable pressure application, poor controllability, and difficulty in accurately simulating actual working conditions. Furthermore, the separation of positioning and pressure detection necessitates repeated disassembly and adjustment during the testing process, leading to low efficiency, especially during large-scale testing. Therefore, to address the aforementioned technical problems, a pressure testing device for pipeline components is proposed. Utility Model Content

By adjusting the spacing of the positioning seats with a screw block to match the length of the pipe parts, when the pipe parts are pushed in, the inclined surface contacts the sealing block and automatically compresses the pressure spring. After passing through, the spring force rebounds and locks the pipe parts to achieve positioning and sealing. Subsequently, the electric push rod pushes the sealing block to simultaneously squeeze the pressure sensor, thereby monitoring the status of the pipe parts under different pressures in real time and realizing the integration of rapid positioning and pressure testing.

[0021] The positioning and sealing mechanism includes a sealing block 15, a compression spring 18, and a telescopic rod 19. The sealing block 15 is slidably connected to the inner side of the second mounting groove 12. The sealing block 15 is used to automatically clamp the end of the pipe part to achieve a seal. The sealing block 15 has a trapezoidal cross-section frustum structure. The inclined area of ​​the sealing block 15 protrudes from the inner side of the guide groove 10. The inclined design facilitates the smooth insertion of the pipe part. One end of the compression spring 18 and the telescopic rod 19 is fixedly connected to the inner side of the second mounting groove 12.

The push block 24 is fixedly connected to the end of the connecting rod 23 and is used to directly push the sealing block 15.

[0024] The working principle of a pipe fitting pressure testing device based on an embodiment is as follows: When performing pressure testing on pipe fittings of a specific size, firstly, the distance between the positioning seat 2 and the push seat 7 is adjusted according to the length of the pipe fitting. Then, the screw 5 is rotated within the slot 3 by turning the screw block 6. Since the locking block 4 and the screw 5 are threadedly engaged, the locking block 4 drives the positioning seat 2 to move towards the push seat 7 until the distance between the two guide grooves 10 matches the length of the pipe fitting. Subsequently, both ends of the pipe fitting are pushed into the space between the positioning seat 2 and the push seat 7, fitting against the guide grooves 10. When one end of the pipe fitting contacts the inclined surface of the sealing block 15, under the action of the thrust, the sealing block 15 compresses the compression spring 18 and moves backward under the guidance of the sliding groove 16 and the slider 17. After the end of the pipe fitting passes the inclined surface of the sealing block 15, the elastic force of the compression spring 18 drives the sealing block 15 to quickly rebound and tightly abut against the inserted pipe fitting. At the end of the pipe component, automatic positioning and initial sealing of the pipe component are achieved. At this time, the electric push rod 21 is activated, and its output shaft drives the connecting rod 23 and the push block 24 through the connecting plate 22 to push the sealing block 15, which pushes the push seat 7 to move towards the positioning seat 2 as a whole. This causes the other end of the pipe component to press against the protective plate 14 outside the pressure sensor 13. The pressure sensor 13 monitors the pressure on the pipe component in real time. By observing the state of the pipe component under different pressure values, such as whether it is damaged, the pressure test can be completed. This device realizes the rapid positioning of the pipe component and the convenient pressure test process.
