ABSTRACT

Aiming at the air tightness test requirements of a clean Angle valve, an automatic valve air tightness test system based on virtual instrument technology is designed and developed. This system adopts the direct pressure method and the difference pressure method to carry on the redundant design, which makes the system has strong reliability. Furthermore, the system uses LabWindows/CVI as the software development platform, which makes the system has strong expansibility. The actual test shows that the system can realize the automatic detection of the valve tightness.
