- Abstract
- The article describes a possible mechanism for the occurrence of parametric resonance in adjusting and safety valves with coil twisted cylindrical springs used in the petroleum industry, in pneumatic and hydraulic highways of liquid rocket engines, in centralized city heat and water supply highways. Conditions for providing dynamic stability of oscillatory processes in valves with spring elements are obtained, which reduces risk of valve destruction and, accordingly, associated environmental risks.
