Abstract

Abstract High performance backpressure valve is critical for the high-pressure fluid control technology. However, the back pressure easily suffers mechanical failure caused by the strong fluid flushing when the back pressure up to 30 MPa. This work used computational fluid dynamics and solid mechanics analysis method to analyze the basic flow and resistance characteristics of a recently developed backpressure valve. The inlet pressure, maximum flow rate, and maximum turbulent kinetic energy of the 2-30MPa backpressure valve decreases with the increasing the valve opening were analyzed in details. There is pressure suppression phenomenon in the valve chamber when the valve opening is less than 6 mm. The fluid-solid coupling results show that the existing structure of the flow channel and valve core seat can satisfy the pressure regulation requirements within the strength range, and the structure of ball spool seat improve the pressure regulation ability.
