Pressure Valves New Symbols Accurately Illustrating Their Transitory Working
Journal Title: RECENT - Year 2011, Vol 12, Issue 33
Abstract
The paper proposes an interpretation of pressure valves used in hydraulic circuits from the point of view of control techniques. Structural models of the pressure valves highlight the classic structure components of control circuits: reference block, comparator, pressure transducer, execution elements etc. Furthermore, original symbols are proposed for the representation of pressure reducing valves to accurately illustrate their function. The new proposed symbols highlight the instantaneous opening of valve spool. Thus the drawback of standardized symbol is eliminated.
