【Abstract】 A new concept in hydraulic pressure control valves, the obtainable maximum pressure, is established. Based on the theory of clearance flow, the mathematic models of the obtainable maximum pressure are deduced. Through a few simplifications the non-dimensional formulas are obtained. The effects of the main factors on the obtainable maximum pressure are discussed. The concept and the mathematical models provide theoretical and practical instruction in the study of hydraulic pressure control valve and its reliability, particularly, in study of ultra-high pressure and water hydraulic valve.更多还原
