[0002] FTIV, or high-pressure tank flow control valve, is a valve that closes without flow. The full name is high-pressure tank flow control valve. FTIV can be opened electrically as needed, and has two mechanical bypasses. Once the pressure in the tank exceeds the preset limit, the excessive or low pressure can be adjusted. In the FTIV production process, the shell structure of the control valve needs to be welded by ultrasonic welding, and after welding, it needs to be tested by testing equipment to detect the air tightness after welding;

[0003] At present, the leakage detection of ultrasonic welding process for FTIV cannot achieve effective docking connection between the valve body and the detection equipment, which leads to reduced detection accuracy due to inaccurate pipeline connection position of the valve body during the detection process. At the same time, since the valve body pipeline and the detection equipment cannot be effectively sealed, the air tightness is low, which is also easy to cause large deviations in detection accuracy.
