Abstract:
A gas module valve test fixture comprising:a tank having an input port and an output port, said tank being capable of holding a pressurized gas;a pressurized gas source connected by a gas line to said input port;a gas flow controller positioned in said gas line between said gas source and said tank, said flow controller adjusted so as to provide an essentially steadily rising gas pressure in said tank as said tank fills with gas from said gas source;a valve under test connected to receive said gas from said tank output port;a pressure sensor connected to produce a first signal indicating gas pressure between said valve under test and said tank; anda calculator electrically coupled to receive said first pressure signal from said pressure sensor, wherein said calculator uses said first signal to calculate an opening pressure of said valve under test, said calculator comprises a visual display of elements of said test fixture, and said calculator allows control of selected said elements of said test fixture with a computer pointing device.
