VALVE BLOCK TEST APPARATUS |
摘要 |
<p>A test apparatus for measuring activation and de activation times of solenoid-operated pilot and air-operated cartridge valves in a valve block assembly for an air-operated IS glassware-forming machine. The test apparatus includes pressure transducers for selective individual connection to the outputs of the solenoid and cartridge valves of a valve block assembly, and an array of electrical switches for selectively energizing the solenoid of a solenoid valve to be tested. A first pair of counters measure activation and de-activation times of the solenoid valve under test, and a second pair of counters measure activation and de-activation times of a solenoid/cartridge valve combination under test. The measured times are displayed in milliseconds at associated numeric displays. A flow meter is connected to the exhaust port of a cartridge valve under test for measuring leakage of air past the seals and seats of the cartridge valve.</p> |
