Dynamic Simulation Research on Deepwater Gate Valve Actuator Based on SimulationX

Abstract

Abstract:

Deepwater gate valve actuator is the power component to control the switch of deepwater gate valve via a hydraulic way. On account of special working conditions and the structure characteristics of the deepwater gate valve actuator, the dynamical model of the deepwater gate valve actuator under the hydraulic control is established considering the damping effects of the flow guide hole, and the SimulationX software is used for dynamic simulation. By analyzing and comparing the simulation results, the feasibility of the simulation is verified. The results can provide reference for the optimization design and dynamic characteristics research of the deepwater gate valve actuator.

Key words: subsea production system, deepwater gate valve actuator, dynamic simulation, SimulationX
