THE STUDY OF THROTTLE POPPET VALVE STRUCTURE
The velocity, pressure, stream function and velocity magnitude in different case are discussed by numerical analysis and simulation ofthe fluid flow in the throttle poppet valve structure. When radian throttle orifice of the seat is 0.5mm, there is a small negative pressure in a distance of throttle, and air erosion is less than that of no rounded throttle orifice of the seat, and energy is full used. The throttle poppet valve flow coefficient Cd iS gotten in different Renault value Re by experiment and numerical analysis, and the numerical analysis result tally with the experiment result. When Renault value is less than 200, experiment value and numerical analysis value coincide. It showns to be better in small Renault value Ro than that in large Renault value Re.The result by improving orifice of valve seat is helpful and optimizing some design parameters ofthe throttle poppet valve structure.
