AI Technical Summary

Technical Problem

Existing inflation pressure testing devices require stopping the machine to adjust the sealing head when changing to different specifications of tee pipes. This results in poor versatility, and the mechanical hard sealing can easily damage the pipe fittings. It is also difficult to adapt to pipe diameter deviations, leading to unreliable sealing and low testing efficiency.

Method used

The design employs a sealing component, including a transmission mechanism with a push block, a sliding block, and a sliding groove. The internal threaded block and the threaded rod work alternately to achieve automatic adjustment of the sealing head spacing. It combines rigid sealing with flexible sealing and adapts to pipe diameter deviations through a sealing sleeve.

Benefits of technology

It enables automated testing of tee pipes of different specifications, avoids pipe end damage, and improves sealing reliability and testing efficiency.
