Operational Reliability of the Valves

摘要

In the paper is presented the factors that influence the reliability of the valves to can determine the ways of increasing it based on the causes of defects and their evaluation. After many researches was finding that by following in operation the behavior of more than 20 valves from each family, the component element that influences the reliability of the serial system, of the valve, is the stem gasket, and the result of the researches are connected around the fluid leakages from the gland gasket.
