Abstract:This paper introduces a external adjust type absolute pressure reduce with equilibrium valve, with simple configuration, small size and low weight,is able to provide a steady operation pressure and effectively meets the performance requirement of mass flow capacity under low pressure.According to its function and performance require,By the load analysis,calculation and comparing of the reducer,derived pressure characteristics and flow characteristics formula,it summarized the effect of inlet pressure(Pinlet) on the outlet pressure (Poutlet) through the parameters of the reduce ,and according to the characteristic,Aim at low pressure and mass flow require, specific plan and pressure reducer parameters(F、f、f活、K1、K2) is given. At last through experiment verify its performance meet the design requirements completely.
