Study on the Stability of Spring Valve Considering the Inlet Pipeline,φ = 90° about valve stability characteristics. The motion of the valve tends to be unstable when the flow deflection angle is close to 90°. Small spring precompression and short inlet pipelines increase the stable operating range of the spring valve.

Modelling the Three-Stage of Creep,e where the strain rate reaches its minimum; (3) the second transition point, that is the transition point between steady and accelerated creep; and (4) the instability point. This research follows the work publish by Crevecoeur [.] and is based on a combination of an exponential and a power law approach to the creep test data of HDPE pipe sample.
