Abstract:
A safety valve is set up to keep the attitude control system in a safe range．The regu— lator is designed to ensure the regulator orifice to be a critical crosssection in any case．The pressure is decreased through the regulator but it is still much higher than the atmospheric pressure．Because of the swirl and friction，the discharge port of the safety valve maintains a critical crosssection．The pressure and flowrate can be calculated by the convergent nozzle formula．The experiment results show that the mathematical model iS credible．
