Background technique

All kinds of pipeline connection castings are necessary products for pipeline connection. After the pipeline connection casting products are processed, they need to undergo a pressure test. The existing electronic airtight testing machines mostly use manual loading and unloading. When the electronic airtight testing machine carries out the pressure test on several pipeline connection castings at the same time, since the electronic airtight testing machine is only equipped with an electronic pressure detector, it is impossible to directly determine which one is leaking when detecting leakage. It is necessary to change the position and conduct multiple tests to determine the leaking parts, and the detection process is cumbersome; at the same time, the existing electronic airtight testing machine uses several cylinders, resulting in waste of equipment investment and compressed air; moreover, the existing electronic airtight testing machine The airtightness testing machine uses a set of electronic airtightness detection system to carry out the withstand voltage test on the pipeline connection castings, resulting in slowdown, low work efficiency and insufficient use of workshop space. How to improve the detection efficiency of pipeline connection casting pressure test, reduce equipment investment and waste of compressed air, and make full use of workshop space are problems that need to be solved.

After the compression is in place, the air-tight detection solenoid valve is opened to inflate the 6 pipeline connection castings and the 6 electronic pressure detectors. After the pressure is balanced, the air-tight detection solenoid valve is closed. The electronic pressure detector starts to detect the pressure change in the corresponding pipeline connection casting. If the pressure change within the set time is within the specified range, it proves that the workpiece is intact; if it exceeds the specified range, the display of the electronic pressure detector changes from green to red, which proves that the workpiece leaks. After the detection is completed, the compression cylinder automatically rises, takes out the leaking parts, steps on the foot switch of the parts discharge, and the push part cylinder pushes the lower cross bar of the rectangular bracket to automatically push out the castings connected with the intact pipeline, and a detection cycle is completed.
