Abstract: Aiming at electrically operated water valves for household and similar use, according to the relevant varieties of international and national standards, the safety testing system was developed based on gas-water pressure combined control, water temperature closed cycle and two level pressure vessel technology, which fulfilled the safety testing system featured with water pressure and temperature programmable and pressure dynamic stability for the safety test of electrically operated water valves. The results indicate that the system can complete the safety test for electrically operated water valves accurately and reliably.
Key words: electrically operated water valves; safety test; gas-water pressure combined control; closed cycles; two level pressure vessel
