An Investigation of the Novel Testing Setup for the Dynamic Characterization of Super High-Pressure High-Speed Switch Valves

Abstract

A novel design of the setup for testing super high-pressure high-speed switch valves is proposed that provides more accurate dynamic characteristics and reduces the hardware and energy expenses. After reviewing the traditional setups for testing high-speed switch valves, we introduced the architecture and the working principle of the novel setup. Subsequently, a numerical comparison study is performed to confirm that the novel setup provides the same conditions for testing the switch valves as the common setup. The test rig for the super high-pressure high-speed switch valve was concurrently built to confirm the feasibility of the novel idea. The experimental results demonstrated that the novel setup meets the standard of testing the super high-pressure high-speed switch valves and can measure the dynamic flow rate signal. An overall appraisal of the novel setup is conducted and its advantages and disadvantages are discussed. In conclusion, the advantages of the new design are significant when it is applied for repeatability and durability tests of the super high-pressure high-speed switch valves.
